This article explores strategies for packing and unpacking payloads into JPEG images using standard console commands and no external tools or special steganography software. I find it amusing how easy it is to hide arbitrary data in JPEG images that otherwise appear normal! Images with unexpected trailing binary data will be quickly flagged by antivirus systems, or the trailing data will be stripped when the image is re-encoded, but the easy detection of binary payloads in images is somewhat offset by the simplicity and availability of this method, allowing JPEG images to be appended with arbitrary binary payloads on virtually any system. https://swharden.com/blog/2026-03-05-git-activity-merge/ Thu, 05 Mar 2026 01:15:00 +0000 https://swharden.com/blog/2026-03-05-git-activity-merge/ I enjoy gazing at the green squares in my GitHub Contribution Graph as a way to visualize the ebbs and flows of my development efforts over the last decade. However, I’ve been working more in repositories on other platforms (GitLab, Azure, and locally) which are not tracked by GitHub and do not contribute to their activity graph. I sought a solution to reclaim those hard-earned green squares! This page documents how I created an anonymized git activity aggregator that integrates commits across various untracked git repositories into a single private repo that can be used to accurately reflect my total development effort as green squares on GitHub’s Contribution Graph. https://swharden.com/blog/2025-11-16-streaming-pi-digits/ Sun, 16 Nov 2025 19:30:00 +0000 https://swharden.com/blog/2025-11-16-streaming-pi-digits/ This page describes a strategy for calculating pi one digit at a time using a streaming algorithm that does not require floating point arithmetic. Although there are more exotic strategies for calculating pi, this one is surprisingly simple to implement, and it streams the digits of pi infinitely. Before we dive in, give it a try in your browser! TheoryIt has long been known that pi can be represented as the product of an infinite series. https://swharden.com/blog/2025-06-08-sensor/ Sun, 08 Jun 2025 11:38:00 +0000 https://swharden.com/blog/2025-06-08-sensor/ I spent the last few years experimenting with designs for internet-enabled temperature sensors so I could monitor the relationship between my indoor, outdoor, garage, and attic temperatures over long time spans. This page documents my favorite implementations using NodeMCU, a USB powered and programmable Arduino-compatible IoT development board with an ESP8266 WiFi module that can be purchased on Amazon in small quantities for about $5 each. The design presented on this page uses a DS18B20 1-Wire thermometer packaged in a weatherproof enclosure sold in small quantities for about $2 each. https://swharden.com/blog/2025-04-13-evenly-spaced-resampled-segmented-line/ Sun, 13 Apr 2025 16:12:00 +0000 https://swharden.com/blog/2025-04-13-evenly-spaced-resampled-segmented-line/ I recently had the need to convert a segmented line (polyline) with arbitrary node points to one with evenly spaced points. After exploring a few solutions I settled on the following two strategies because of their simplicity and performance. Code on this page avoids trigonometric functions and square root operations to enhance performance. Resampling for Equal Distance Along the Length of the LineSimple linear interpolation may be employed to place points at specific distances along the length of the line. https://swharden.com/blog/2024-12-27-data-smoothing-csharp/ Fri, 27 Dec 2024 15:36:00 +0000 https://swharden.com/blog/2024-12-27-data-smoothing-csharp/ Optimized Simple Moving Average AlgorithmThe simple moving average (SMA) for an array of length N using a window of size W can be efficiently calculated using a running sum maintained in memory. As the window moves along the data, new values are shifted into it by adding their value to the running sum, and old values are shifted out by subtracting their value from the running sum. This strategy reduces the number of operations from approximately O(N*W) to O(N) which offers considerable performance enhancement for applications requiring large smoothing windows. https://swharden.com/blog/2024-09-14-swarmfit/ Sat, 14 Sep 2024 16:00:00 +0000 https://swharden.com/blog/2024-09-14-swarmfit/ This article describes how to fit arbitrary curves with any number of parameters to X/Y data points using C#. The strategy described here uses particle swarm optimization to iteratively work toward an optimal solution. Unlike other curve fitting strategies, the first derivative of the error function does not need to be calculated mathematically, making it particularly useful for problems where the solution landscape is noisy, nonlinear, or completely unknown. Users only need to provide a function and the limits for each parameter, and the swarm will converge on the optimal solution. https://swharden.com/blog/2024-08-24-exponential-fit-csharp/ Sat, 24 Aug 2024 20:09:00 +0000 https://swharden.com/blog/2024-08-24-exponential-fit-csharp/ This article describes how to perform a simple exponential fit using pure C#. Exponential curves which pass through 0 can be described using two variables, so data can be translated into linear space, fitted using a linear least squares strategy, then translated back into exponential space. // These are the data points we wish to fit double[] xs = [1, 2, 3, 4, 5, 6, 7]; double[] ys = [258, 183, 127, 89, 65, 48, 35]; // Log-transform values, then perform a linear fit double[] logYs = ys. https://swharden.com/blog/2024-08-17-github-license-checker/ Sat, 17 Aug 2024 19:45:00 +0000 https://swharden.com/blog/2024-08-17-github-license-checker/ Adding a permissive license to your open source projects makes it easy for others to benefit from reusing your code. I typically recommend the MIT license for most projects because it’s simple, well understood, and allows the code to be used for essentially any purpose. Using code from websites and GitHub repositories without a license is difficult, because as I understand it the default terms are “all rights reserved” by the copyright holder unless explicitly stated otherwise. https://swharden.com/blog/2024-02-19-local-ai-chat-csharp/ Wed, 28 Feb 2024 21:15:00 +0000 https://swharden.com/blog/2024-02-19-local-ai-chat-csharp/ This page describes how I use C# to run the LLaMA 2 large language model (LLM) locally to achieve AI chat, including the ability to answer questions about local documents. I previously described how I run LLama2 locally using Python (and how I use it to answer questions about documents). Although the Python ecosystem is fantastic for end-users who are strong programmers, setting-up the development environment required to run Python scripts can be a challenge. https://swharden.com/blog/2023-08-31-avr-dd-frequency-counter/ Thu, 31 Aug 2023 18:40:00 +0000 https://swharden.com/blog/2023-08-31-avr-dd-frequency-counter/ Modern AVR microcontrollers have asynchronous counters that can be externally driven to count pulses from 1 Hz to beyond 100 MHz. Over the years I’ve explored various methods for building frequency counters typically using the SN74LV8154 32-bit counter, but my new favorite method uses the AVR64DD32 microcontroller ($1.52 on Mouser) to directly measure a signal and report its frequency to a PC using a USB serial adapter. I’m working on a special frequency counter project which builds upon this strategy, but I found the core concept to be interesting enough that I decided to write about it in its own article. https://swharden.com/blog/2023-08-26-spi-flash-audio/ Sat, 26 Aug 2023 20:00:00 +0000 https://swharden.com/blog/2023-08-26-spi-flash-audio/ This project uses a microcontroller’s PWM output to drive a speaker and play audio stored in a SPI flash chip. This article combines what was learned in my two previous articles: play audio with a microcontroller and use a FT232H to program a SPI flash chip which go into more detail about the circuitry and code behind each of these major steps. By encoding audio at 8-bit resolution with an 8 kHz sample rate, 32 Mb (4 MB) of memory is sufficient to store approximately 8 minutes of raw audio. https://swharden.com/blog/2023-08-24-ft232h-spi-flash/ Thu, 24 Aug 2023 19:00:00 +0000 https://swharden.com/blog/2023-08-24-ft232h-spi-flash/ FTFlash is a Windows application for reading and writing SPI flash memory with a FT232H breakout board. I created FTFlash to be an easy to use click-to-run alternative to existing strategies that use console applications, complex python distributions, or custom USB drivers. FTFlash source code is on GitHub and a zip file containing the EXE can be downloaded from the FTFlash releases page. This page demonstrates interfacing a W25Q32, but the strategies described here should work for any SPI flash chip. https://swharden.com/blog/2023-08-22-avr-ice-power/ Tue, 22 Aug 2023 19:45:00 +0000 https://swharden.com/blog/2023-08-22-avr-ice-power/ The Atmel ICE is a development tool for programming and debugging Atmel microcontrollers, but it does not have the ability to power devices under test. Older AVR series microcontrollers could be programmed with inexpensive ICSP programmers that carried a VCC line, but the newest series of AVR microcontrollers cannot be programmed with ICSP. See my Programming Modern AVR Microcontrollers article for information about options for programming these chips using inexpensive gear. https://swharden.com/blog/2023-08-19-speaking-microcontroller/ Sat, 19 Aug 2023 23:00:00 +0000 https://swharden.com/blog/2023-08-19-speaking-microcontroller/ This page describes the technique I used to get a microcontroller to speak numbers out loud. Reading numbers from a speaker is an interesting and simple alternative to displaying numbers on a display, which often requires complex multiplexing circuitry and/or complex software to drive the display. This page describes the techniques I used to extract audio waveforms from MP3 files and encode them into data that can be stored in the microcontroller’s flash memory. https://swharden.com/blog/2023-07-30-summarizing-blog-posts-with-ai/ Mon, 31 Jul 2023 23:09:00 +0000 https://swharden.com/blog/2023-07-30-summarizing-blog-posts-with-ai/ This page describes how I used a locally hosted generative AI to read blog posts I made as a child and summarize them using more professional language. In the early 2000s there was no Twitter, and the equivalent was making short blog posts every few days. Today this website is effectively a technology blog, and although I’m proud to have been blogging for over twenty years, I’m embarrassed enough by some of the content I wrote as a child that I have hundreds of posts hidden. https://swharden.com/blog/2023-07-30-ai-document-qa/ Sun, 30 Jul 2023 09:30:00 +0000 https://swharden.com/blog/2023-07-30-ai-document-qa/ This page describes how I use Python to ingest information from documents on my filesystem and run the Llama 2 large language model (LLM) locally to answer questions about their content. My ultimate goal with this work is to evaluate feasibility of developing an automated system to digest software documentation and serve AI-generated answers to technical questions based on the latest available information. UPDATE: A C# version of this article has been created. https://swharden.com/blog/2023-07-29-ai-chat-locally-with-python/ Sat, 29 Jul 2023 18:30:00 +0000 https://swharden.com/blog/2023-07-29-ai-chat-locally-with-python/ This page describes how to interact with the Llama 2 large language model (LLM) locally using Python, without requiring internet, registration, or API keys. We will deliver prompts to the model and get AI-generated chat responses using the llama-cpp-python package. UPDATE: A C# version of this article has been created. Code on this page describes a Python-centric strategy for running the LLama2 LLM locally, but a newer article I wrote describes how to run AI chat locally using C# (including how to have it answer questions about documents) which some users may find easier to follow. https://swharden.com/blog/2023-05-13-static-site-link-checking/ Sat, 13 May 2023 13:39:00 +0000 https://swharden.com/blog/2023-05-13-static-site-link-checking/ This website is a static site containing thousands of pages, and I recently had the desire to check all of them for broken links and images. Although it would be a tedious task to perform manually, I was able to automate the process using Python. This page describes the process I used to identify broken links and images and may be helpful to others using static site generator tools like Jekyll, Hugo, Eleventy, Pelican, Gatsby, other Jamstack site generators, or hand-written HTML files. https://swharden.com/blog/2023-03-07-treemapping/ Tue, 28 Mar 2023 00:32:00 +0000 https://swharden.com/blog/2023-03-07-treemapping/ Treemap diagrams display a series of positive numbers using rectangles sized proportional to the value of each number. This page demonstrates how to calculate the size and location of rectangles to create a tree map diagram using C#. Although the following uses System.Drawing to save the tree map as a Bitmap image, these concepts may be combined with information on the C# Data Visualization page to create treemap diagrams using SkiaSharp, WPF, or other graphics technologies. https://swharden.com/blog/2023-03-05-dotnet-code-analysis/ Sun, 05 Mar 2023 15:20:00 +0000 https://swharden.com/blog/2023-03-05-dotnet-code-analysis/ This page describes how to use the Microsoft.CodeAnalysis.Metrics package to perform source code analysis of .NET assemblies from a console application. Visual Studio users can perform source code analysis by clicking the “Analyze” dropdown menu and selecting “Calculate Code Metrics”, but I sought to automate this process so I can generate custom code analysis reports from console applications as part of my CI pipeline. Performing Code AnalysisStep 1: Add the Microsoft. https://swharden.com/blog/2022-12-17-avr-1pps/ Sat, 17 Dec 2022 13:09:00 +0000 https://swharden.com/blog/2022-12-17-avr-1pps/ I often find it useful to gate frequency counters using a 1 pulse per second (1PPS) signal derived from a 10 MHz precision frequency reference. However, a divide-by-10-million circuit isn’t trivial to implement. Counter ICs exist which enable divide-by-100 by combining multiple divide-by-2 and divide-by-5 stages (e.g., MC74HC390A around $0.85 each), but dividing 10 MHz all the way down to 1Hz would require at least 4 of these chips and a lot of wiring. https://swharden.com/blog/2022-12-09-avr-programming/ Fri, 09 Dec 2022 23:45:00 +0000 https://swharden.com/blog/2022-12-09-avr-programming/ This page describes how to program Microchip’s newest series of AVR microcontrollers using official programming gear and software. I spent many years programming the traditional series of Atmel chips, but now several years after Microchip acquired Atmel I am interested in exploring the capabilities of the latest series of AVR microcontrollers (especially the new AVR DD family). Currently the global chip shortage makes it difficult to source traditional ATMega and STM32 chips, but the newest series of AVR microcontrollers feature an impressive set of peripherals for the price and are available from all the major vendors. https://swharden.com/blog/2022-11-14-hx710b-arduino/ Tue, 15 Nov 2022 00:30:00 +0000 https://swharden.com/blog/2022-11-14-hx710b-arduino/ This page demonstrates how to read differential voltage from a HX710 ADC using Arduino. I recently obtained some pressure sensor boards from Amazon for less than $3 each under names like 6pcs 3.3-5V Digital Barometric Air Pressure Sensor Module Liquid Water Level Controller Board 0-40KPa that use this ADC. Several years ago I worked on a precision pressure meter project based on an I2C temperature and pressure sensor (MS5611), and now that I see new inexpensive SPI pressure sensor modules on the consumer market I’m interested to learn more about their capabilities. https://swharden.com/blog/2022-11-04-csharp-create-bitmap/ Mon, 07 Nov 2022 18:45:00 +0000 https://swharden.com/blog/2022-11-04-csharp-create-bitmap/ This project how to represent bitmap data in a plain old C object (POCO) to create images from scratch using C# and no dependencies. Common graphics libraries like SkiaSharp, ImageSharp, System.Drawing, and Maui.Graphics can read and write bitmaps in memory, so a POCO that stores image data and converts it to a bitmap byte allows creation of platform-agnostic APIs that can be interfaced from any graphics library. This page demonstrates how to use C# (. https://swharden.com/blog/2022-10-16-psk31-synthesis/ Sun, 16 Oct 2022 23:26:00 +0000 https://swharden.com/blog/2022-10-16-psk31-synthesis/ PSK-31 is a narrow-bandwidth digital mode which encodes text as an audio tone that varies phase at a known rate. To learn more about this digital mode and solve a challenging programming problem, I’m going to write a PSK-31 encoder and decoder from scratch using the C# programming language. All code created for this project is open-source, available from my PSK Experiments GitHub Repository, and released under the permissive MIT license. https://swharden.com/blog/2022-06-23-resample-interpolation/ Thu, 23 Jun 2022 21:15:00 +0000 https://swharden.com/blog/2022-06-23-resample-interpolation/ Cubic spline interpolation can be used to modify the sample rate of time series data. This page describes how I achieve signal resampling with spline interpolation in pure C# without any external dependencies. This technique can be used to: Convert unevenly-sampled data to a series of values with a fixed sample rate Convert time series data from one sample rate to another sample rate Fill-in missing values from a collection of measurements https://swharden.com/blog/2022-05-29-blazor-loading-progress/ Sun, 29 May 2022 16:05:00 +0000 https://swharden.com/blog/2022-05-29-blazor-loading-progress/ Today I created a Blazor WebAssembly app that shows a progress bar while the page loads. This is especially useful for users on slow connections because Blazor apps typically require several megabytes of DLL and DAT files to be downloaded before meaningful content appears on the page.

This page offers a quick look at how to use this new library to draw graphics using SkiaSharp in a .NET 6 console application. The C# Data Visualization site has additional examples for drawing and animating graphics using Microsoft.Maui.Graphics in Windows Forms and WPF applications. https://swharden.com/blog/2022-05-01-dotnet-dataframe/ Sun, 01 May 2022 23:00:00 +0000 https://swharden.com/blog/2022-05-01-dotnet-dataframe/ The DataFrame is a data structure designed for manipulation, analysis, and visualization of tabular data, and it is the cornerstone of many data science applications. One of the most famous implementations of the data frame is provided by the Pandas package for Python. An equivalent data structure is available for C# using Microsoft’s data analysis package. Although data frames are commonly used in Jupyter notebooks, they can be used in standard . https://swharden.com/blog/2022-04-24-github-actions-ftp/ Sun, 24 Apr 2022 16:45:00 +0000 https://swharden.com/blog/2022-04-24-github-actions-ftp/ This article describes how I use GitHub Actions to deploy content using FTP without any third-party dependencies. Code executed in continuous deployment pipelines may have access to secrets (like FTP credentials and SSH keys). Supply-chain attacks are becoming more frequent, including self-sabotage by open-source authors. Without 2FA, the code of well-intentioned maintainers is one stolen password away from becoming malicious. For these reasons I find it imperative to eliminate third-party Actions from my CI/CD pipelines wherever possible. https://swharden.com/blog/2022-04-12-github-badge/ Tue, 12 Apr 2022 23:00:00 +0000 https://swharden.com/blog/2022-04-12-github-badge/ I created a badge to dynamically display stats for any public GitHub repository using HTML and Vanilla JavaScript. I designed it so anyone can have their own badge by copying two lines of HTML into their website. I don’t write web frontend code often, so after getting this idea I decided to see how far I could take it. I treated this little project as an opportunity to get some experience exploring a stack I don’t interact with often, and to see if I could take it all the way to something that would look nice and scale infinitely for free. https://swharden.com/blog/2022-04-06-mystify/ Mon, 04 Apr 2022 18:34:00 +0000 https://swharden.com/blog/2022-04-06-mystify/ This article explores my recreation of the classic screensaver Mystify your Mind implemented using C#. I used SkiaSharp to draw graphics and FFMpegCore to encode frames into high definition video files suitable for YouTube. The Mystify Sandbox application has advanced options allowing exploration of various configurations outside the capabilities of the original screensaver. Interesting configurations can be exported as video (x264-encoded MP4 or WebM format) or viewed in full-screen mode resembling an actual screensaver. https://swharden.com/blog/2022-03-20-github-actions-hugo/ Sun, 20 Mar 2022 22:45:00 +0000 https://swharden.com/blog/2022-03-20-github-actions-hugo/ This article describes how I safely use GitHub Actions to build a static website with Hugo and deploy it using SSH without any third-party dependencies. Code executed in continuous deployment pipelines may have access to secrets (like FTP credentials and SSH keys). Supply-chain attacks are becoming more frequent, including self-sabotage by open-source authors.

Consider the simple task where you want to accept a generic array and return its sum. With .NET 6 (and features currently still in preview), this got much easier! public static T Sum<T>(T[] values) where T : INumber<T> { T sum = T.Zero; for (int i = 0; i < values.Length; i++) sum += values[i]; return sum; } To use this feature today you must: https://swharden.com/blog/2022-02-01-point-in-rectangle/ Tue, 01 Feb 2022 00:10:00 +0000 https://swharden.com/blog/2022-02-01-point-in-rectangle/ I recently had the need to determine if a point is inside a rotated rectangle. This need arose when I wanted to make a rotated rectangular textbox draggable, but I wanted to determine if the mouse was over the rectangle. I know the rectangle’s location, size, and rotation, and the position of the mouse cursor, and my goal is to tell if the mouse is inside the rotated rectangle. In this example I’ll use Maui. https://swharden.com/blog/2022-01-22-spline-interpolation/ Sat, 22 Jan 2022 16:00:00 +0000 https://swharden.com/blog/2022-01-22-spline-interpolation/ I recently had the need to create a smoothed curve from a series of X/Y data points in a C# application. I achieved this using cubic spline interpolation. I prefer this strategy because I can control the exact number of points in the output curve, and the generated curve (given sufficient points) will pass through the original data making it excellent for data smoothing applications. The code below is an adaptation of original work by Ryan Seghers (links below) that I modified to narrow its scope, support double types, use modern language features, and operate statelessly in a functional style with all static methods. https://swharden.com/blog/2021-11-17-ndepend-badges/ Sun, 17 Oct 2021 13:20:00 +0000 https://swharden.com/blog/2021-11-17-ndepend-badges/ Many project websites and readmes have status badges that display build status, project details, or code metrics. badgen.net and shields.io are popular services for dynamically generating status badges as SVG files using HTTP requests.

Images are all JPEG format, but unfortunately they have filenames like DSC_0123.JPG. This means there are many identical filenames (e.g., every folder has a DSC_0001.JPG) and also the sorted list of filenames would not be in chronological order. JPEG files have an Exif header and most cameras store the acquisition date of photographs as metadata. https://swharden.com/blog/2021-10-09-console-secrets/ Sat, 09 Oct 2021 13:15:00 +0000 https://swharden.com/blog/2021-10-09-console-secrets/ Sometimes your code needs to work with secrets that you don’t want to risk accidentally leaking on the internet. There are many strategies for solving this problem, and here I share my preferred approach. I see a lot of articles about how to manage user secrets in ASP.NET and other web applications, but not many focusing on console or desktop applications.

MAUI will be released as part of .NET 6 in November 2021 and it is expected to come with Maui.Graphics, a cross-platform drawing library superior to System.Drawing in many ways. Although System.Drawing.Common currently supports rendering in Linux and MacOS, cross-platform support for System.Drawing will sunset over the next few releases and begin throwing a PlatformNotSupportedException in . https://swharden.com/blog/2021-08-01-maui-skia-console/ Sun, 01 Aug 2021 19:15:00 +0000 https://swharden.com/blog/2021-08-01-maui-skia-console/ Microsoft’s System.Drawing.Common package is commonly used for cross-platform graphics in .NET Framework and .NET Core applications, but according to the dotnet roadmap System.Drawing will soon only support Windows. As Microsoft sunsets cross-platform support for System.Drawing they will be simultaneously developing Microsoft.Maui.Graphics, a cross-platform graphics library for iOS, Android, Windows, macOS, Tizen and Linux completely in C#. The Maui.Graphics library can be used in any .NET application (not just MAUI applications).

Images commonly encountered on the internat are 24-bit or 32-bit RGB images (where each pixel is represented by 8 bits each for red, green, blue, and possibly alpha). Typical image analysis libraries and documentation often lack information about how to work with 16-bit image data. This page summarizes how I work with 16-bit TIF file data in C#. https://swharden.com/blog/2021-06-03-images-in-memory/ Thu, 03 Jun 2021 00:03:00 +0000 https://swharden.com/blog/2021-06-03-images-in-memory/ This page is a quick reference for programmers interested in working with image data in memory (byte arrays). This topic is straightforward overall, but there are a few traps that aren’t necessarily intuitive so I try my best to highlight those here. 💡 See my newer article, Creating Bitmaps from Scratch in C# This article assumes you have some programming experience working with byte arrays in a C-type language and have an understanding of what is meant by 32-bit, 24-bit, 16-bit, and 8-bit integers. https://swharden.com/blog/2021-05-16-python-deploy-ftps/ Sun, 16 May 2021 11:00:00 +0000 https://swharden.com/blog/2021-05-16-python-deploy-ftps/ Python can be used to securely deploy website content using FTPS. Many people have used a FTP client like FileZilla to drag-and-drop content from their local computer to a web server, but this method requires manual clicking and is error-prone. If you write a script to accomplish this task it lowers the effort barrier for deployment (encouraging smaller iterations) and reduces the risk you’ll accidentally do something unintentional (like deleting an important folder by accident). https://swharden.com/blog/2021-05-15-python-credentials/ Sat, 15 May 2021 21:00:00 +0000 https://swharden.com/blog/2021-05-15-python-credentials/ I enjoy contributing to open-source, but I’d prefer to keep my passwords to myself! Python is a great glue language for automating tasks, and recently I’ve been using it to log in to my web server using SFTP and automate log analysis, file management, and software updates. The Python scripts I’m working on need to know my login information, but I want to commit them to source control and share them on GitHub so I have to be careful to use a strategy which minimizes risk of inadvertently leaking these secrets onto the internet. https://swharden.com/blog/2021-03-27-wspr-code-generator/ Sat, 27 Mar 2021 20:00:00 +0000 https://swharden.com/blog/2021-03-27-wspr-code-generator/ WSPR (Weak Signal Propagation Reporter) is a protocol for weak-signal radio communication. Transmissions encode a station’s callsign, location (grid square), and transmitter power into a frequency-shift-keyed (FSK) signal that hops between 4 frequencies to send 162 tones in just under two minutes. Signals can be decoded with S/N as low as −34 dB! WSJT-X, the most commonly-used decoding software, reports decoded signals to wsprnet.org so propagation can be assessed all over the world. https://swharden.com/blog/2021-01-31-xml-doc-name-reflection/ Sun, 31 Jan 2021 13:57:00 +0000 https://swharden.com/blog/2021-01-31-xml-doc-name-reflection/ In C#, you can document your code using XML directly before code blocks.

This change broke some of my PHP scripts because __DIR__ suddenly had a base path that was different than DOCUMENT_ROOT, and the str_replace method I was using to determine the directory URL assumed they would always be the same.

The graphics model logic is entirely C# and the web interface has user-facing options (razor components) to customize its behavior in real time. To render a frame JavaScript calls a C# function that returns JSON containing an array of line details (colors and coordinates) so a JavaScript render function can draw them on a HTML canvas. https://swharden.com/blog/2021-01-08-blazor-boids/ Fri, 08 Jan 2021 22:58:00 +0000 https://swharden.com/blog/2021-01-08-blazor-boids/ This project implements the Boids flocking algorithm in C# and uses Blazor WebAssembly to render it in the browser. Drone birds (bird-oids, or boids) follow a simple set of rules to determine their angle and velocity. When many boids are placed in a field together, interesting group behaviors emerge. Details about the boid flocking algorithm are discussed in depth elsewhere. This article summarizes how to configure a Blazor application to model graphics with C# and render them with JavaScript. https://swharden.com/blog/2021-01-07-blazor-canvas-animated-graphics/ Thu, 07 Jan 2021 21:46:00 +0000 https://swharden.com/blog/2021-01-07-blazor-canvas-animated-graphics/ Client-side Blazor allows C# graphics models to be rendered in the browser. This means .NET developers can create web apps with business logic written (and tested) in C# instead of being forced to write their business logic in a totally different language (JavaScript) just to get it to run in the browser. In this project we’ll create an interactive graphics model (a field of balls that bounce off the edge of the screen) entirely in C#, and draw the model on the screen using an API that allows us to interact with a HTML5 Canvas. https://swharden.com/blog/2021-01-06-new-blazor-net5-project/ Wed, 06 Jan 2021 19:39:00 +0000 https://swharden.com/blog/2021-01-06-new-blazor-net5-project/ When Visual Studio 2019 creates a new Blazor app it defaults to .NET Standard 2.1. A few months ago .NET 5 was released, and upgrading Blazor apps to use .NET 5 has many strong performance improvements. I’m sure a Visual Studio update will soon make this easier, but for now to create a new .NET Blazor app running .NET 5 I use these steps: Create a new .NET core 3.1 Blazor App Edit the csproj file Change SDK from Microsoft. https://swharden.com/blog/2020-12-29-blazor-build-info/ Tue, 29 Dec 2020 19:54:00 +0000 https://swharden.com/blog/2020-12-29-blazor-build-info/ I find it useful to add build date and .NET version to the bottom of my client-side applications.

Join the QRSS Knights mailing list for the latest QRSS news. The QRSS hobby owes much of its success to the extraordinary efforts of amateur radio operators who run and maintain QRSS grabber stations. QRSS grabbers are built by pairing a radio receiver with a computer running software to continuously convert the received signals into spectrogram images which are uploaded to the internet every few minutes. https://swharden.com/blog/2020-10-11-model-neuron-ltspice/ Sun, 11 Oct 2020 22:24:00 +0000 https://swharden.com/blog/2020-10-11-model-neuron-ltspice/ By modeling a voltage-clamp amplifier, patch pipette, and cell membrane as a circuit using free circuit simulation software, I was able to create a virtual patch-clamp electrophysiology workstation and challenge model neurons with advanced voltage-clamp protocols. By modeling neurons with known properties and simulating experimental membrane test protocols, I can write membrane test analysis software and confirm its accuracy by comparing my calculated membrane measurements to the values in the original model. https://swharden.com/blog/2020-10-03-new-age-of-qrss/ Sat, 03 Oct 2020 22:08:00 +0000 https://swharden.com/blog/2020-10-03-new-age-of-qrss/ QRSS is an experimental radio mode that uses frequency-shift-keyed (FSK) continuous wave (CW) Morse code to transmit messages that can be decoded visually by inspecting the radio frequency spectrogram. The name “QRSS” is a derivation of the Q code “QRS”, a phrase Morse code operators send to indicate the transmitter needs to slow down. The extra “S” means slow way, way down, and at the typical speed of 6 second dots and 18 second dashes most QRSS operators have just enough time to send their call sign once every ten minutes (as required by federal law). https://swharden.com/blog/2020-09-27-ecg-simulator-circuit/ Sun, 27 Sep 2020 17:11:00 +0000 https://swharden.com/blog/2020-09-27-ecg-simulator-circuit/ This page describes a simple circuit which produces ECG-like waveform. The waveform is not very detailed, but it contains a sharp depolarizing (rising) component, a slower hyperpolarizing (falling) component, and a repetition rate of approximately one beat per second making it potentially useful for testing heartbeat detection circuitry. In 2019 I released a YouTube video and blog post showing how to build an ECG machine using an AD8232 interfaced to a computer’s sound card. https://swharden.com/blog/2020-09-26-ltspice-mod-files/ Sun, 27 Sep 2020 16:21:00 +0000 https://swharden.com/blog/2020-09-26-ltspice-mod-files/ This page shows how to use the LM741 op-amp model file in LTSpice. This is surprisingly un-intuitive, but is a good thing to know how to do. Model files can often be downloaded by vendor sites, but LTSpice only comes pre-loaded with models of common LT components. Step 1: Download a Model (.mod) FileI found LM741.MOD available on the TI’s LM741 product page.

I favor SciPy’s filtfilt function because the filtered data it produces is the same length as the source data and it has no phase offset, so the output always aligns nicely with the input. The sosfiltfilt function is even more convenient because it consumes filter parameters as a single object which makes them easier work with.

The Wayback Machine is an impressive website that lets you view what a website looked like years ago. As part of Archive.org Internet Archive, this website is truly impressive and holds entertainingly-old versions of most webpages. Just look at Amazon.com in the year 2000 for a good laugh. I started this blog as a child twenty years ago and after seeing what the Wayback Machine pulled-up I realized that it may be best that the thoughts I had as a child stay in the past. https://swharden.com/blog/2020-09-13-leaving-wordpress/ Sun, 13 Sep 2020 18:15:00 +0000 https://swharden.com/blog/2020-09-13-leaving-wordpress/ After fifteen years using WordPress, I’m leaving it for a simpler alternative: flat markdown files. There were several reasons behind why I made the change. First, I was disappointed with how frequently I had to update WordPress (and upgrade my database) to stay current with security updates. Second, I didn’t like how abstract post content was. The text of posts was stored in SQL tables and references to image URLs weren’t easily accessible (posts point to content IDs, the URLs of which were stored in another table), and images and media were scattered all over the filesystem because the default image placement changed several times over the years. https://swharden.com/blog/2019-08-03-usb-frequency-counter/ Sat, 03 Aug 2019 21:15:00 +0000 https://swharden.com/blog/2019-08-03-usb-frequency-counter/ I built a frequency counter with a USB interface based around a 74LV8154 32-bit counter, FTDI FT230XS (USB serial adapter), and an ATMega328 microcontroller. I’ve used this same counter IC in some old projects (1, 2, 3, 4, 5) this time I decided to I design the circuit a little more carefully, make a PCB, and use all surface-mount technology (SMT). The micro USB port provides power and PC connectivity, and when running the device sends frequency to the computer every second. https://swharden.com/blog/2019-07-31-upgraded-amplifier/ Wed, 31 Jul 2019 21:00:00 +0000 https://swharden.com/blog/2019-07-31-upgraded-amplifier/ The design is similar (CMOS buffer driving an IRF510) but I used perfboard to make this one and placed it in an enclosure. There’s no low-pass filter on the amplifier itself, but I put a 30m low-pass filter in-line the coax before the antenna. It’s currently outputting 20PPV into 50 ohms (1 watt).

Stack (average of 13 grabs) 2019-07-30I spotted my signal across the Atlantic. It’s pretty weak, but you can just make out the unique shape on EA8BVP’s grabber in the Canary Islands (4,000 miles away). https://swharden.com/blog/2019-07-26-smt-qrss-design/ Fri, 26 Jul 2019 21:00:00 +0000 https://swharden.com/blog/2019-07-26-smt-qrss-design/ This page documents development of a voltage-controlled oscillator suitable for QRSS. Source code and PCB files are on https://github.com/swharden/QRSS-hardware For QRSS it’s convenient to have 2 frequency shift adjustments: a coarse one to set frequency (~200 Hz), and a fine one for FSK (5 Hz). I began with the design below allowing manual adjustment of coarse tuning, then an external input for fine tuning. Eventually I switched to a design where a single voltage controls tuning (coarse and fine). https://swharden.com/blog/2019-07-21-new-keyer/ Sun, 21 Jul 2019 21:00:00 +0000 https://swharden.com/blog/2019-07-21-new-keyer/ I’d like to use an interesting pattern that takes advantage of both FSK and OOK. I want it to be 5 Hz or less in bandwidth, and I want it to be unique and recognizable in cases where only a few seconds are spotted, but I don’t want it to be so odd that it’s annoying. I came up with something like: Here’s what it looks like on the air: https://swharden.com/blog/2019-07-20-qrss-stitch-and-stack/ Sat, 20 Jul 2019 21:00:00 +0000 https://swharden.com/blog/2019-07-20-qrss-stitch-and-stack/ If the transmitter frequency is stable, transmissions start every 10 minutes, and grabbers are time-aligned to be every 10 minutes, multiple grabs can be averaged together to enhance signal-to-noise ratio. This is called QRSS Image Stacking. To simplify the process of making these images I created a new tool for the job: QRSS Stitch and Stack. https://swharden.com/blog/2019-07-20-qrss-letters/ Sat, 20 Jul 2019 21:00:00 +0000 https://swharden.com/blog/2019-07-20-qrss-letters/ I finished writing the microcontroller code to read the GPS time and only start transmissions when the minutes value ends with a zero. The signal now stacks nicely in 10-minute grabs. Now that GPS and the oven is working well I’ve started sending my call sign (AJ4VD). AJ4VD spotted in Pensacola, FL (W4HBK)First spot occurred while I was actively adjusting the transmission length AJ4VD spotted in Greensboro, NC (WD4ELG) 5x frame stack (mean frame) from the WD4ELG grabber reveals the AJ4VD signal much better, and confirms the GPS timer is working well. https://swharden.com/blog/2019-07-18-ook-and-fsk/ Thu, 18 Jul 2019 21:00:00 +0000 https://swharden.com/blog/2019-07-18-ook-and-fsk/ I got OOK and FSK working together (the S shape in the middle).

The infusion itself was relatively uneventful (a gravity-fed bag of cells flowed into my PICC line for about an hour) but it represents a big day for me and a shot at one day having a healthy immune system. After the infusion the transplant team came in and sang happy birthday to celebrate! While I spent the last week in the hospital focused on getting through chemotherapy to gear up for this transplant day, the next few weeks are focused more on preventing infections and managing symptoms related to the continuing drop in my immune function as my white blood cell count approaches zero. https://swharden.com/blog/2019-03-26-last-day-of-chemotherapy/ Tue, 26 Mar 2019 13:55:00 +0000 https://swharden.com/blog/2019-03-26-last-day-of-chemotherapy/ I just finished my last bag of pre-transplant chemotherapy! As of this morning the doctors said they are pleased with my numbers, and things are looking good so far. Even though the chemotherapy infusions stopped today, my blood counts will continue to drop (to near zero) over the next couple weeks during which I’ll be feeling really lousy. For now though, I feel surprisingly good (my medications are doing a great job of controlling the pain and nausea) and while my blood counts are high enough I’m even allowed to take occasional little walks around the hospital with a mask. https://swharden.com/blog/2019-03-15-proceeding-with-bmt/ Fri, 15 Mar 2019 23:55:00 +0000 https://swharden.com/blog/2019-03-15-proceeding-with-bmt/ A few days ago I got the phone call I was hoping for – We are proceeding with a bone marrow transplant! An autologous bone marrow transplant is a procedure which may give me a chance at growing a new and healthy immune system (capable of fighting the cancer) from stem cells previously collected from my blood. When I first started chemotherapy in August the hope was that it would suppress my lymphoma enough that I could safely proceed with the transplant. https://swharden.com/blog/2019-03-15-sound-card-ecg-with-ad8232/ Fri, 15 Mar 2019 23:50:34 +0000 https://swharden.com/blog/2019-03-15-sound-card-ecg-with-ad8232/ Every few years I revisit the idea of building an ECG machine. This time I was very impressed with how easy it is to achieve using the AD8232, a single-lead ECG front-end on a chip. The AD8232 is small (LFCSP package) but breakout boards are easy to obtain online. Many vendors on eBay sell kits that come with electrode cables and pads for under $20. Sparkfun sells a breakout board but you have to buy the cable and electrodes separately. https://swharden.com/blog/2019-01-02-stem-cell-collection-day/ Wed, 02 Jan 2019 23:22:00 +0000 https://swharden.com/blog/2019-01-02-stem-cell-collection-day/ I didn’t have an out-of-body experience today, but my blood did! This morning a catheter was placed in my left internal jugular vein with two tubes to allow continuous withdraw and replacement of blood as it circulated through an apheresis machine to filter-out and collect white blood cells (leukapheresis). This procedure harvests hematopoietic stem cells which can be frozen and later used used to repopulate my bone marrow after it is destroyed by strong chemotherapy as part of my autologous bone marrow transplant. https://swharden.com/blog/2018-09-13-scott-has-a-new-look/ Thu, 13 Sep 2018 20:55:00 +0000 https://swharden.com/blog/2018-09-13-scott-has-a-new-look/ I decided a while back that I’d shave my hair off as soon as I first noticed it falling out, and that day has come! Almost every day before I go to sleep I give it a little tug and think, “still in there!”, but this morning I noticed it falling out in the shower. By lunch I was getting annoyed as hair kept landing on my keyboard at work. My coworker Jeff offered to shave it off at his place after work, and I couldn’t get it off fast enough! https://swharden.com/blog/2018-08-29-first-round-of-chemotherapy/ Wed, 29 Aug 2018 19:50:00 +0000 https://swharden.com/blog/2018-08-29-first-round-of-chemotherapy/ I started my first round of chemotherapy today! I expect to feel pretty lousy for the first few days after each infusion (the next one being 3 weeks from now), but I’m very happy that treatment has begun. The chemotherapy regimen I am undergoing is called CHOP, an acronym for the combination of drugs used: The C (cyclophosphamide) is an alkylating antineoplastic agent which damages DNA by promoting the formation of interstrand and intrastrand crosslinkages leading to cell death. https://swharden.com/blog/2018-08-24-port-placed-today/ Fri, 24 Aug 2018 11:18:00 +0000 https://swharden.com/blog/2018-08-24-port-placed-today/ I got my port placed today! A port is a medical appliance surgically implanted beneath the skin which is attached to a a tube which goes into a large blood vessel (a central venous catheter, CVC). Instead of poking my arms to draw blood, deliver chemotherapy medication, or inject IV contrast dye during medical imaging, my port can be accessed instead. Update (2018-12-13): A chest X-ray taken today displays my port quite nicely! https://swharden.com/blog/2018-08-16-pet-ct-reveals-progression/ Thu, 16 Aug 2018 11:45:00 +0000 https://swharden.com/blog/2018-08-16-pet-ct-reveals-progression/ In July 2018, after 6 years of careful observation while my disease rested in an indolent state, the lymphoma kicked into gear and started growing rapidly. I experienced an abnormal increase in generalized lymphadenopathy (beyond the level I had come to get used to as normal), and a CT revealed thoracic and axial lymph nodes which were significantly larger than typical. A PET CT revealed high metabolic activity in many chains of lymph nodes, indicating the disease had shifted in its behavior from indolent to aggressive. https://swharden.com/blog/2018-06-06-things-are-starting-to-change/ Wed, 06 Jun 2018 11:45:00 +0000 https://swharden.com/blog/2018-06-06-things-are-starting-to-change/ My first realization that something was changing in the status of my disease came while filming a YouTube video about FTDI microchips. I noticed the cervical lymph nodes on my left side were swollen, took a selfie to assess what they looked like, then kept shooting the video with my body turned in such a way as to minimize the notability of my left neck. For the record here’s the picture, and here’s the video. https://swharden.com/blog/2018-06-03-bit-bang-ftdi-usb-to-serial-converters-to-drive-spi-devices/ Sun, 03 Jun 2018 18:51:30 +0000 https://swharden.com/blog/2018-06-03-bit-bang-ftdi-usb-to-serial-converters-to-drive-spi-devices/ The FT232 USB-to-serial converter is one of the most commonly-used methods of adding USB functionality to small projects, but recently I found that these chips are capable of sending more than just serial signals. With some creative programming, individual output pins can be big-banged to emulate a clock, data, and chip select line to control SPI devices. This post shares some of the techniques I use to bit-bang SPI with FTDI devices, and some of the perks (and quirks) of using FTDI chips to bit-bang data from a USB port. https://swharden.com/blog/2017-12-19-iot-festivus-pole/ Tue, 19 Dec 2017 22:11:17 +0000 https://swharden.com/blog/2017-12-19-iot-festivus-pole/ The Internet of Things now includes Festivus poles! **Festivus is a holiday celebrated on December 23rd, and its customary practices include a Festivus pole, Festivus dinner, airing of grievances, feats of strength, and Festivus miracles. The internet contains a few nods to the holiday, including what happens when you Google for the word Festivus (a Festivus pole is displayed at the bottom of the page). In 2015 I had the honor of gifting the world with the first Festivus pole video game, and today I am happy to unveil the world’s first internet-enabled Festivus pole. https://swharden.com/blog/2017-09-09-hurricane-hack-diy-led-candle/ Sat, 09 Sep 2017 11:27:43 +0000 https://swharden.com/blog/2017-09-09-hurricane-hack-diy-led-candle/ Florida is about to get hit by a massive hurricane, and my home town is in the direct path! I am well prepared with lots of food, water, and communications equipment. While the storm itself is dangerous, part of getting ready for it means preparing for the potential to be out of power for weeks. A staple go-to for light when the power is out is candles. Instinctively people tend to reach for candles and kerosene lamps (in Florida they’re called hurricane lanterns). https://swharden.com/blog/2017-09-02-ps4-controller-hack-adding-auto-run/ Sat, 02 Sep 2017 15:48:22 +0000 https://swharden.com/blog/2017-09-02-ps4-controller-hack-adding-auto-run/ After a long day it can be really nice to have a relaxing hobby to clear your head, and few activities shut down your brain as effectively as video games. However, a newly released video game is physically hurting me as my impulse to move quickly causes me to perpetually click the run button. After a few days of game-play and a really sore left thumb, I decided to do something about it: hack-in a microchip to automatically click the button for me. https://swharden.com/blog/2017-08-20-microcontroller-action-potential-generator/ Sun, 20 Aug 2017 15:12:33 +0000 https://swharden.com/blog/2017-08-20-microcontroller-action-potential-generator/ __Here I demonstrate how to use a single microcontroller pin to generate action-potential-like waveforms. __The output is similar my fully analog action potential generator circuit, but the waveform here is created in an entirely different way. A microcontroller is at the core of this project and determines when to fire action potentials. Taking advantage of the pseudo-random number generator (rand() in AVR-GCC’s stdlib.h), I am able to easily produce unevenly-spaced action potentials which more accurately reflect those observed in nature. https://swharden.com/blog/2017-08-12-analog-action-potential-generator-circuit/ Sat, 12 Aug 2017 23:04:32 +0000 https://swharden.com/blog/2017-08-12-analog-action-potential-generator-circuit/ __Few biological cells are as interesting to the electrical engineer as the neuron. Neurons are essentially capacitors (with a dielectric cell membrane separating conductive fluid on each side) with parallel charge pumps, leak currents, and nonlinear voltage-dependent currents. __When massively parallelized, these individual functional electrical units yield complex behavior and underlie consciousness. The study of the electrical properties of neurons (neurophysiologically, a subset of electrophysiology) often involves the development and use of sensitive electrical equipment aimed at studying these small potentials produced by neurons and currents which travel through channels embedded in their membranes. https://swharden.com/blog/2017-08-02-ttl-triggered-stimulus-generator/ Wed, 02 Aug 2017 21:08:00 +0000 https://swharden.com/blog/2017-08-02-ttl-triggered-stimulus-generator/ I was presented with a need to rapidly develop a pulse generator to take a TTL input and output a programmable output (for now 0.1 ms pulses at 20 Hz for as long as the input is high). I achieved this with a one-afternoon turnaround and the result looks great! This post documents the design and fabrication of this prototype device, with emphasis placed on design considerations and construction technique. https://swharden.com/blog/2017-06-28-controlling-speakers-with-radar/ Wed, 28 Jun 2017 21:56:24 +0000 https://swharden.com/blog/2017-06-28-controlling-speakers-with-radar/ I just finished building a device that uses RADAR to toggle power to my speakers when it detects my hand waiving near them! I have some crummy old monitor speakers screwed to a shelf, and although their sound is decent the volume control knob (which also controls power) is small and far back on my work bench and inconvenient to keep reaching for. I decided to make a device which would easily let me turn the speakers on and off without having to touch anything. https://swharden.com/blog/2017-04-29-precision-pressure-meter-project/ Sat, 29 Apr 2017 13:15:07 +0000 https://swharden.com/blog/2017-04-29-precision-pressure-meter-project/ I just completed building a device capable of measuring temperature to one hundredth of a degree Celsius and pressure to one ten-thousandth of a PSI! This project is centered around a MS5611 temperature sensor breakout board which was small enough to fit inside of a plastic syringe. The result is a small and inexpensive pressure sensor in a convenient form factor with a twist connector (a Luer-Lok fitting) that can be rapidly attached to existing tubing setups. https://swharden.com/blog/2017-02-04-logging-i2c-data-with-bus-pirate-and-python/ Sat, 04 Feb 2017 13:13:44 +0000 https://swharden.com/blog/2017-02-04-logging-i2c-data-with-bus-pirate-and-python/ I’m working on a project which requires I measure temperature via a computer, and I accomplished this with minimal complexity using a BusPirate and LM75A I2C temperature sensor. I already had some LM75A breakout boards I got on eBay (from China) a while back. A current eBay search reveals these boards are a couple dollars with free shipping. The IC itself is available on Mouser for $0.61 each. The LM75A datasheet reveals it can be powered from 2. https://swharden.com/blog/2017-02-02-rotary-encoder/ Thu, 02 Feb 2017 22:48:53 +0000 https://swharden.com/blog/2017-02-02-rotary-encoder/ __Rotary encoders are a convenient way to add complex input functionality to small hardware projects with a single component. __Rotary encoders (sometimes called shaft encoders, or rotary shaft encoders) can spin infinitely in both directions and many of them can be pressed like a button. The volume knob on your car radio is probably a rotary encoder. With a single component and 3 microcontroller pins I can get six types of user input: turn right, turn left, press-and-turn right, press-and-turn left, press and release, and press and hold. https://swharden.com/blog/2016-10-10-raspberry-pi-rf-frequency-counter/ Mon, 10 Oct 2016 02:58:41 +0000 https://swharden.com/blog/2016-10-10-raspberry-pi-rf-frequency-counter/ I build a lot of RF circuits, and often it’s convenient to measure and log frequency with a computer. Previously I’ve built standalone frequency counters, frequency counters with a PC interface, and even hacked a classic frequency counter to add USB interface (twice, actually). My latest device uses only 2 microchips to provide a Raspberry Pi with RF frequency measurement capabilities. The RF signal clocks a 32-bit counter SN74LV8154 ($1.04 on Mouser) connected to a 16-bit IO expander MCP23017 ($1. https://swharden.com/blog/2016-09-28-generating-analog-voltages-with-the-raspberry-pi/ Wed, 28 Sep 2016 22:26:29 +0000 https://swharden.com/blog/2016-09-28-generating-analog-voltages-with-the-raspberry-pi/ I recently had the need to generate analog voltages from the Raspberry PI, which has rich GPIO digital outputs but no analog outputs. I looked into the RPi.GPIO project which can create PWM (which I wanted to smooth using a low pass filter to create the analog voltage), but its output on the oscilloscope looked terrible! It stuttered all over the place, likely because the duty is continuously under software control. https://swharden.com/blog/2016-09-19-hacking-a-cheap-ammeter-voltmeter-to-provide-a-bluetooth-pc-interface/ Mon, 19 Sep 2016 11:46:11 +0000 https://swharden.com/blog/2016-09-19-hacking-a-cheap-ammeter-voltmeter-to-provide-a-bluetooth-pc-interface/ I love analyzing data, so any time I work with a device that measures something, I usually want to save its output. I’ve lately come to enjoy the cheap panel-mount volt meters and current meters on eBay, and figured it would be cool to hack one to provide PC logging capability. After getting a few of these devices for ~$8 each on eBay and probing around, I realized they didn’t output measurement data on any of the pins (not that I really expected they would), so I coded a microcontroller to watch the lines of the multiplexed 7-segment display and figure out what the screen is displaying (an odd technique I’ve done once or twice before), then send its value to a computer using the microcontroller’s UART capabilities. https://swharden.com/blog/2016-09-09-adding-adc-to-microcontrollers-without-adc/ Fri, 09 Sep 2016 03:00:31 +0000 https://swharden.com/blog/2016-09-09-adding-adc-to-microcontrollers-without-adc/ I recently had the need to carefully measure a voltage with a microcontroller which lacks an analog-to-digital converter (ADC), and I hacked together a quick and dirty method to do just this using a comparator, two transistors, and a few passives. The purpose of this project is to make a crystal oven controller at absolute minimal cost with minimal complexity. Absolute voltage accuracy is not of high concern (i.e., holding temperature to 50. https://swharden.com/blog/2016-09-05-vhf-frequency-counter-with-pc-interface/ Mon, 05 Sep 2016 17:34:44 +0000 https://swharden.com/blog/2016-09-05-vhf-frequency-counter-with-pc-interface/ Projects I build often involve frequency synthesis, and one of the most useful tools to have around is a good frequency counter. I love the idea of being able to access / log / analyze frequency readings on my computer. Commercial frequency counters can be large, expensive, and their calibration is a chicken-and-egg problem (you need a calibrated frequency counter to calibrate a frequency reference you use to calibrate a frequency counter! https://swharden.com/blog/2016-08-31-ics501-simple-frequency-multiplier/ Wed, 31 Aug 2016 03:57:50 +0000 https://swharden.com/blog/2016-08-31-ics501-simple-frequency-multiplier/ Today I made a high frequency multiplier using a single component: the ICS501 PLL clock multiplier IC. This chip provides 2x, 5x, 8x (and more) clock multiplication using an internal phased-lock loop (PLL). At less than a dollar on eBay, $1.55 on mouser, and $0.67 on Digikey, they don’t break the bank and I’m glad I have a few in my junk box! I have a 10MHz frequency standard which I want to use to measure some 1Hz (1pps) pulses with higher precision, so my general idea is to use a frequency multiplier circuit to increase the frequency (to 80 MHz) and use this to run a counter IC to measure the number of clock pulses between the PPS pulses. https://swharden.com/blog/2016-08-24-tenma-multimeter-serial-hack/ Wed, 24 Aug 2016 03:08:28 +0000 https://swharden.com/blog/2016-08-24-tenma-multimeter-serial-hack/ I just spent the afternoon reverse-engineering the 72 series TENMA multimeter serial interface, and can now access all of its readings from a standalone Python script. This lets me send all measurements made with the multimeter to my computer in real time (using an optically isolated connection), and eliminates the need for the TENMA PC interface software. In addition to allowing the development of custom software to use measurements from TENMA multimeters in real time, this project also lets allows TENMA multimeters to interface with Linux computers (such as the raspberry pi). https://swharden.com/blog/2016-08-20-breadboard-line-driver-module/ Sat, 20 Aug 2016 19:16:27 +0000 https://swharden.com/blog/2016-08-20-breadboard-line-driver-module/ Sometimes I rapidly want to amplify a signal, but building amplifiers, buffers, and line drivers can be a hassle, especially on a breadboard! It’s important to know how to carefully design build tuned and untuned amplifier circuits, but sometimes you just want to analyze or work with a signal without modifying it by sinking too much current, so being able to rapidly drop in a buffer stage would be a great help. https://swharden.com/blog/2016-08-08-diy-ecg-with-1-op-amp/ Mon, 08 Aug 2016 01:49:24 +0000 https://swharden.com/blog/2016-08-08-diy-ecg-with-1-op-amp/ ⚠️ Check out my newer ECG design: Sound Card ECG with AD8232 I made surprisingly good ECG from a single op-amp and 5 resistors! An ECG (electrocardiograph, sometimes called EKG) is a graph of the electrical potential your heart produces as it beats. Seven years ago I posted DIY ECG Machine on the Cheap which showed a discernible ECG I obtained using an op-amp, two resistors, and a capacitor outputting to a PC sound card’s microphone input. https://swharden.com/blog/2016-07-31-real-time-audio-monitor-with-pyqt/ Sun, 31 Jul 2016 15:21:11 +0000 https://swharden.com/blog/2016-07-31-real-time-audio-monitor-with-pyqt/ A new project I’m working on requires real-time analysis of soundcard input data, and I made a minimal case example of how to do this in a cross-platform way using python 3, numpy, and PyQt. Previous posts compared performance of the matplotlib widget vs PyQtGraph plotwidget and I’ve been working with PyQtGraph ever since. For static figures matplotlib is wonderful, but for fast responsive applications I’m leaning toward PyQtGraph. The full source for this project is on a github page, but here’s a summary of the project. https://swharden.com/blog/2016-07-31-live-data-in-pyqt4-with-plotwidget/ Sun, 31 Jul 2016 07:28:28 +0000 https://swharden.com/blog/2016-07-31-live-data-in-pyqt4-with-plotwidget/ After spending a day comparing performance of MatplotlibWidget with PlotWidget, when it comes to speed PlotWidget wins by a mile! Glance over my last post where I describe how to set up the window with QT Designer and convert the .ui file to a .py file. With only a few changes to the code, I swapped the matplotlib _MatplotlibWidget _with the pyqtgraph PlotWidget. I easily got a 20x increase in speed (frame rate), and I’m likely to favor PyQtGraph over matpltolib for python applications involving realtime display of data. https://swharden.com/blog/2016-07-30-live-data-in-pyqt4-with-matplotlibwidget/ Sat, 30 Jul 2016 23:15:23 +0000 https://swharden.com/blog/2016-07-30-live-data-in-pyqt4-with-matplotlibwidget/ I keep getting involved in projects which require live data to be graphed in real time. Since most of my back-end is written in Python, it makes sense to have a Pythonic front-end. Cross-platform GUI programming in Python is frustratingly non-trivial, as there multiple window frameworks available (TK, GTK, and QT) and their respective graphical designers (torture, Glade, and QT Designer) and each has its own way of doing things. Add different ways to plot data in the mix (gnuplot, matplotlib, and custom widgets) and it can become a complicated mess. https://swharden.com/blog/2016-07-28-opto-isolated-laser-controller-build/ Thu, 28 Jul 2016 02:33:12 +0000 https://swharden.com/blog/2016-07-28-opto-isolated-laser-controller-build/ This page documents the design and build of a small device to interface a modern fiber-coupled DPSS laser with old scientific hardware designed to control mechanical relays. This project involves analog and digital circuitry, microcontrollers, and lasers, and it turned out to be a pretty cool build so I’m sharing the design and construction process online in case it will be helpful for others or even my future self. The existing hardware I must interface is made by Coulbourn Instruments and is essentially just a large multi-channel computer-controlled DAC/ADC. https://swharden.com/blog/2016-07-19-realtime-audio-visualization-in-python/ Tue, 19 Jul 2016 04:44:48 +0000 https://swharden.com/blog/2016-07-19-realtime-audio-visualization-in-python/ Python’s “batteries included” nature makes it easy to interact with just about anything… except speakers and a microphone! As of this moment, there still are not standard libraries which which allow cross-platform interfacing with audio devices. There are some pretty convenient third-party modules, but I hope in the future a standard solution will be distributed with python. I appreciate the differences of Linux architectures such as ALSA and OSS, but toss in Windows and MacOS in the mix and it gets to be a huge mess. https://swharden.com/blog/2016-07-14-controlling-bus-pirate-with-python/ Thu, 14 Jul 2016 00:15:31 +0000 https://swharden.com/blog/2016-07-14-controlling-bus-pirate-with-python/ After using the AVR-ISP mkII for years (actually the cheap eBay knock-offs) to program ATMEL AVR microcontrollers, today I gave the Bus Pirate a shot. Far more than just a microcontroller programmer, this little board is basically a serial interface to basic microcontroller peripherals. In a nutshell, you plug it in via USB and it looks like a serial port which has a command-line interface that lets you do things like turn pins on and off, perform voltage measurements, and it naively supports bidirectional use of common protocols like I2C, SPI, UART, and even HD44780 series LCDs. https://swharden.com/blog/2015-12-23-festivus-pole-video-game/ Wed, 23 Dec 2015 18:24:11 +0000 https://swharden.com/blog/2015-12-23-festivus-pole-video-game/ December 23 is Festivus! To commemorate the occasion, I have built a traditional Festivus pole with a couple added features. To my knowledge, this is the first electronic Festivus pole on the internet. Festivus is a holiday comically celebrated as an alternative to the pressures of commercialism commonly associated with other winter holidays. Originating from the 1997 Seinfeld episode “The Strike”, the traditions of Festivus include demonstrating feats of strength, declaring common occurrences as Festivus miracles, airing of grievances, and of course the fabrication of a Festivus pole. https://swharden.com/blog/2014-04-19-epoch-timestamp-hashing/ Sat, 19 Apr 2014 08:31:53 +0000 https://swharden.com/blog/2014-04-19-epoch-timestamp-hashing/ I was recently presented with the need to rename a folder of images based on a timestamp. This way, I can keep saving new files in that folder with overlapping filenames (i.e., 01.jpg, 02.jpg, 03.jpg, etc.), and every time I run this script all images are prepended with a timestamp. I still want the files to be sorted alphabetically, which is why an alphabetical timestamp (rather than a random hash) is preferred. https://swharden.com/blog/2014-02-27-directly-driving-7-segment-display-with-avr-io-pins/ Thu, 27 Feb 2014 16:19:53 +0000 https://swharden.com/blog/2014-02-27-directly-driving-7-segment-display-with-avr-io-pins/ I came across the need for a quick and dirty display to show a 4 digit number from a microcontroller. The right way to do this would be to use a microcontroller in combination with a collection of transistors and current limiting resistors, or even a dedicated 7-segment LED driver IC. The wrong way to do this is to wire LEDs directly to microcontroller IO pins to source and sink current way out of spec of the microcontroller… and that’s exactly what I did! https://swharden.com/blog/2013-06-23-calculate-qrss-transmission-time-with-python/ Sun, 23 Jun 2013 21:19:59 +0000 https://swharden.com/blog/2013-06-23-calculate-qrss-transmission-time-with-python/ How long does a particular bit of Morse code take to transmit at a certain speed? This is a simple question, but when sitting down trying to design schemes for 10-minute-window QRSS, it doesn’t always have a quick and simple answer. Yeah, you could sit down and draw the pattern on paper and add-up the dots and dashes, but why do on paper what you can do in code? The following speaks for itself. https://swharden.com/blog/2013-06-22-adding-usb-to-a-cheap-frequency-counter-again/ Sat, 22 Jun 2013 20:07:22 +0000 https://swharden.com/blog/2013-06-22-adding-usb-to-a-cheap-frequency-counter-again/ Today I rigineered my frequency counter to output frequency to a computer via a USB interface. You might remember that I did this exact same thing two years ago, but unfortunately I fell victim to accidental closed source. When I rigged it the first time, I stupidly tried to get fancy and add USB interface with V-USB requiring special drivers and special software code to retrieve the data. The advantage was that the microcontroller spoke directly to the PC USB port via 2 pins requiring no extra hardware. https://swharden.com/blog/2013-06-22-crystal-oven-testing/ Sat, 22 Jun 2013 15:14:37 +0000 https://swharden.com/blog/2013-06-22-crystal-oven-testing/ To maintain high frequency stability, RF oscillator circuits are sometimes “ovenized” where their temperature is raised slightly above ambient room temperature and held precisely at one temperature. Sometimes just the crystal is heated (with a “crystal oven”), and other times the entire oscillator circuit is heated. The advantage of heating the circuit is that other components (especially metal core instructors) are temperature sensitive. Googling for the phrase “crystal oven”, you’ll find no shortage of recommended circuits. https://swharden.com/blog/2013-06-10-precision-temperature-measurement/ Mon, 10 Jun 2013 22:25:27 +0000 https://swharden.com/blog/2013-06-10-precision-temperature-measurement/ In an effort to resume previous work [A, B, C, D] on developing a crystal oven for radio frequency transmitter / receiver stabilization purposes, the first step for me was to create a device to accurately measure and log temperature. I did this with common, cheap components, and the output is saved to the computer (over 1,000 readings a second). Briefly, I use a LM335 precision temperature sensor ($0.70 on mouser) which outputs voltage with respect to temperature. https://swharden.com/blog/2013-06-03-realtime-image-pixelmap-from-numpy-array-data-in-qt/ Mon, 03 Jun 2013 22:40:56 +0000 https://swharden.com/blog/2013-06-03-realtime-image-pixelmap-from-numpy-array-data-in-qt/ Consider realtime spectrograph software like QRSS VD. It’s primary function is to scroll a potentially huge data-rich image across the screen. In Python, this is often easier said than done.__ If you’re not careful, you can tackle this problem inefficiently and get terrible frame rates (<5FPS) or eat a huge amount of system resources (I get complaints often that QRSS VD takes up a lot of processor resources, and 99% of it is drawing the images). https://swharden.com/blog/2013-05-19-wireless-microcontroller-pc-interface-for-3-21/ Sun, 19 May 2013 01:32:46 +0000 https://swharden.com/blog/2013-05-19-wireless-microcontroller-pc-interface-for-3-21/ __Here I demonstrate a dirt-cheap method of transmitting data from any microchip to any PC using $3.21 in parts. __I’ve had this idea for a while, but finally got it working tonight. On the transmit side, I’m having a an ATMEL AVR microcontroller (ATMega48) transmit data (every number from 0 to 200 over and over) wirelessly using 433mhz wireless modules. The PC receives the data through the microphone port of a sound card, and a cross-platform Python script I wrote decodes the data from the audio and graphs it on the screen. https://swharden.com/blog/2013-05-09-realtime-fft-audio-visualization-with-python/ Thu, 09 May 2013 19:52:02 +0000 https://swharden.com/blog/2013-05-09-realtime-fft-audio-visualization-with-python/ WARNING: this project is largely outdated, and some of the modules are no longer supported by modern distributions of Python.For a more modern, cleaner, and more complete GUI-based viewer of realtime audio data (and the FFT frequency data), check out my Python Real-time Audio Frequency Monitor project. I’m no stranger to visualizing linear data in the frequency-domain. Between the high definition spectrograph suite I wrote in my first year of dental school (QRSS-VD, which differentiates tones to sub-Hz resolution), to the various scripts over the years (which go into FFT imaginary number theory, linear data signal filtering with python, and real time audio graphing with wckgraph), I’ve tried dozens of combinations of techniques to capture data, analyze it, and display it with Python. https://swharden.com/blog/2013-05-08-realtime-data-plotting-in-python/ Wed, 08 May 2013 16:34:27 +0000 https://swharden.com/blog/2013-05-08-realtime-data-plotting-in-python/ WARNING: this project is largely outdated, and some of the modules are no longer supported by modern distributions of Python.For a more modern, cleaner, and more complete GUI-based viewer of realtime audio data (and the FFT frequency data), check out my Python Real-time Audio Frequency Monitor project.

I respect PIC, but I find the open/free atmosphere around AVR to be a little more supportive to individual, non-commercial cross-platform programmers like myself. With that being said, I’ve had a few bumps along the way getting unofficial AVR programmers to work in Windows 7. Previously, I had great success with a $11 (shipped) clone AVRISP-mkII programmer from fun4diy. https://swharden.com/blog/2013-04-17-tenma-72-7750-multimeter-excellent-for-rf-engineering/ Wed, 17 Apr 2013 22:20:55 +0000 https://swharden.com/blog/2013-04-17-tenma-72-7750-multimeter-excellent-for-rf-engineering/ Update: This page reviews my initial impressions of the Tenma 72-7750. In a later article (TENMA Multimeter Serial Hack) I use Python to interface this multimeter to make it easier to log data and create plots of measurements without using the official (Windows-only) software. I recently got my hands on a Tenma 72-7750 multimeter.

I’m quite a fan of numpy, scipy, matplotlib, the python imaging library (PIL), and GUI platforms like Tk/TkInter, pyGTK, and pyQT, but getting them all to play nicely is a sometimes pain. I’m considering migrating entirely to Python(x,y) because, as a single distribution, it’s designed to install all these libraries (and many more) in a compatible way out of the box. https://swharden.com/blog/2013-04-14-simple-diy-ecg-pulse-oximeter-version-2/ Sun, 14 Apr 2013 16:00:14 +0000 https://swharden.com/blog/2013-04-14-simple-diy-ecg-pulse-oximeter-version-2/ ⚠️ Check out my newer ECG designs: Sound Card ECG with AD8232 Single op-amp ECG Of the hundreds of projects I’ve shared over the years, none has attracted more attention than my DIY ECG machine on the cheap posted almost 4 years ago. This weekend I re-visited the project and made something I’m excited to share! The original project was immensely popular, my first featured article on Hack-A-Day, and today “ECG” still represents the second most searched term by people who land on my site. https://swharden.com/blog/2013-01-06-avr-programming-in-linux/ Sun, 06 Jan 2013 14:51:19 +0000 https://swharden.com/blog/2013-01-06-avr-programming-in-linux/ It is not difficult to program ATMEL AVR microcontrollers with linux, and I almost exclusively do this because various unofficial (inexpensive) USB AVR programmers are incompatible with modern versions of windows (namely Windows Vista and Windows 7). I am just now setting-up a new computer station in my electronics room (running Ubuntu Linux 12.04), and to make it easy for myself in the future I will document everything I do when I set-up a Linux computer to program microcontrollers. https://swharden.com/blog/2012-12-18-my-diy-bench-power-supply/ Tue, 18 Dec 2012 11:30:27 +0000 https://swharden.com/blog/2012-12-18-my-diy-bench-power-supply/ Another thing everybody needs (and has probably built) is a simple laboratory bench power supply. A lot of people use things like modified PC power supplies but I wasn’t in favor of this because I wanted something smaller, lower current, and cleaner (from an RF perspective). My needs are nothing particularly high power, just something to provide a few common voltages for digital logic and small RF circuits. This is what I came up with! https://swharden.com/blog/2012-12-06-single-wavelength-pulse-oximeter/ Thu, 06 Dec 2012 08:13:41 +0000 https://swharden.com/blog/2012-12-06-single-wavelength-pulse-oximeter/ ⚠️ Check out my newer ECG designs: Sound Card ECG with AD8232 Single op-amp ECG I want to create a microcontroller application which will utilize information obtained from a home-brew pulse oximeter. Everybody and their cousin seems to have their own slant how to make DIY pulse detectors, but I might as well share my experience. Traditionally, pulse oximeters calculate blood oxygen saturation by comparing absorbance of blood to different wavelengths of light. https://swharden.com/blog/2012-08-18-geek-spin-attiny44-project-prototype/ Sat, 18 Aug 2012 15:28:38 +0000 https://swharden.com/blog/2012-08-18-geek-spin-attiny44-project-prototype/ Some days you feel like working on projects to benefit humanity. The day I made this clearly wasn’t one of those days. A little over a year ago, I got into a troll war with my friend Mike Seese. The joke, similar to that of rick rolling, was to get each other to unexpectedly click a link to the Hatsune Miku version of the leekspin song. After several weeks of becoming beyond annoying, I decided to make an actual Hatsune Miku which would spin her leek and bobble her head to the techno version of the Levan Polka for his birthday. https://swharden.com/blog/2012-06-24-introduction-to-pic-programming-from-an-avr-guru/ Sun, 24 Jun 2012 20:29:03 +0000 https://swharden.com/blog/2012-06-24-introduction-to-pic-programming-from-an-avr-guru/ I’m not ashamed to say it: I’m a bit of an ATMEL guy. AVR microcontrollers are virtually exclusively what I utilize when creating hobby-level projects. Wile I’d like to claim to be an expert in the field since I live and breathe ATMEL datasheets and have used many intricate features of these microchips, the reality is that I have little experience with other platforms, and have likely been leaning on AVR out of habit and personal convention rather than a tangible reason. https://swharden.com/blog/2012-06-14-multichannel-usb-analog-sensor-with-atmega48/ Thu, 14 Jun 2012 10:42:00 +0000 https://swharden.com/blog/2012-06-14-multichannel-usb-analog-sensor-with-atmega48/ Sometimes it’s tempting to re-invent the wheel to make a device function exactly the way you want. I am re-visiting the field of homemade electrophysiology equipment, and although I’ve already published a home made electocardiograph (ECG), I wish to revisit that project and make it much more elegant, while also planning for a pulse oximeter, an electroencephalograph (EEG), and an electrogastrogram (EGG). This project is divided into 3 major components: the low-noise microvoltage amplifier, a digital analog to digital converter with PC connectivity, and software to display and analyze the traces. https://swharden.com/blog/2012-06-13-resuming-life/ Wed, 13 Jun 2012 10:41:33 +0000 https://swharden.com/blog/2012-06-13-resuming-life/ I’m staring deeply into a large, ominous, empty white text box on my screen as a small vertical text cursor blinks, staring back at me. I faintly remember writing my first blog entry eleven years ago (to the week), as a 15 year old kid typing on a keyboard in the middle of the night. Every time I log-in to write on my website, I see the same cursor, monotonous in its dependable, unvarying appearance. https://swharden.com/blog/2012-04-16-first-diagnosis/ Mon, 16 Apr 2012 21:00:00 +0000 https://swharden.com/blog/2012-04-16-first-diagnosis/ In April 2012 I had some alarming symptoms and visited an oncologist for the first time. Symptoms included lymphadenopathy, weight loss, night sweats. This picture was taken just before my first doctor visit, and I’m in scrubs because I was a dental student at the time (I hadn’t started the DMD/PhD program yet). After several blood tests and two surgical biopsies I was eventually diagnosed with non-Hodgkin’s lymphoma (NHL). More specifically, Lennert’s Lymphoma, a rare lymphoepithelioid variant of peripheral T-cell lymphoma in the not otherwise specified category T-cell lymphomas. https://swharden.com/blog/2011-08-23-we-love-and-will-miss-you-angelina/ Tue, 23 Aug 2011 01:08:43 +0000 https://swharden.com/blog/2011-08-23-we-love-and-will-miss-you-angelina/ As many of you know, my wife Angelina Harden unexpectedly passed away a couple days ago (Saturday, Aug 20, 2011). I’d like to thank all of our friends for their encouraging words. This is an extremely hard time for her family, my family, and me, and I appreciate the outpouring of support and encouragement. Angelina’s funeral was held in Jackson, Tennessee (the home town of much of Angelina’s family and friends from her past) on September 10th, 2011. https://swharden.com/blog/2011-08-14-high-altitude-balloon-transmitter-prototype/ Sun, 14 Aug 2011 18:42:59 +0000 https://swharden.com/blog/2011-08-14-high-altitude-balloon-transmitter-prototype/ It’s been my goal for quite some time to design a simple, easy-to-replicate transmitter for high altitude balloon telemetry transmission. I’m quite satisfied by what I came up with because it’s very simple, cheap, easy to code for, and easy to change frequency. I’d say the most common alternative is a handheld amateur radio transmitter which starts around $60, requires an amateur radio license, and typically output 5W of FM on 144MHz (2m) or 440MHz (70cm). https://swharden.com/blog/2011-08-14-high-school-students-high-altitude-balloon-2/ Sun, 14 Aug 2011 18:36:12 +0000 https://swharden.com/blog/2011-08-14-high-school-students-high-altitude-balloon-2/ Last year a group of high school students, in collaboration with a seminar course on Space Systems sponsored by the University of Florida’s Student Science Training Program (SSTP), gained some real-world experience planning, building, and launching a research payload to the edge of space – all in a couple weeks! Last year’s high altitude balloon launch was covered on my website, and the radio transmitter I built for it was featured on this Hack-A-Day post. https://swharden.com/blog/2011-08-06-ridiculously-simple-avr-mcu-am-radio-transmitter/ Sat, 06 Aug 2011 19:32:44 +0000 https://swharden.com/blog/2011-08-06-ridiculously-simple-avr-mcu-am-radio-transmitter/ I was brainstorming some RF circuits today and I had the desire to create a rapid transmitter/receiver pair that anyone would have around their house. I decided that AM or FM radio would be good since everyone can receive that, and pondered how best to generate the necessary radio signal and modulate it appropriately. After a few LC oscillator designs, I thought about the RC oscillators built into most micro-controllers. I grabbed an ATMEL AVR I had on hand (an ATTiny44A) and checked the datasheet. https://swharden.com/blog/2011-08-05-i-before-e-except-after-hellschreiber/ Fri, 05 Aug 2011 18:52:40 +0000 https://swharden.com/blog/2011-08-05-i-before-e-except-after-hellschreiber/ This post describes a project I designed which transmits strings of data from a microcontroller to a PC’s screen using audio beeping in a special mode called Hellschreiber. Although these days it’s almost exclusively used by amateur radio operators, I thought it would make a cool microcontroller project! The result can be accomplished with a microcontroller and a speaker as a transmitter and a PC with a microphone as a receiver and decoder, or with actual radio equipment (even toy walkie talkies) by transmitting the tones over modulated radio frequencies for long distance communication! https://swharden.com/blog/2011-07-31-pcmicrocontroller-wireless-data-transfer-part-2/ Sun, 31 Jul 2011 22:35:12 +0000 https://swharden.com/blog/2011-07-31-pcmicrocontroller-wireless-data-transfer-part-2/ This is one part of a multi-post project Last week I had the crazy idea of sending data from a PC to a microchip through the monitor, using javascript and a web interface as a ridiculously simple data transfer platform that would work on virtually any computer! While I quickly hacked together the hardware, I struggled with the web interface (I’m a little slow with javascript) and I got a lot of help from people around the internet, especially after my project (and need for assistance) was mentioned on Hack-A-Day! https://swharden.com/blog/2011-07-26-pcmicrocontroller-wireless-data-transfer/ Tue, 26 Jul 2011 22:35:16 +0000 https://swharden.com/blog/2011-07-26-pcmicrocontroller-wireless-data-transfer/ Several days ago I had a crazy idea. I was driving to Orlando to pick my wife up from the airport and it was dark and stormy on the highway and I was thinking about the backlash I got from my Sound Card Microcontroller/PC Communication project, where I used an embarrassingly simple hardware to accomplish the simple task of exchanging a few bytes of data between a PC and microcontroller (in the face of many people who adamantly prefer more complicated “traditional standard” methods). https://swharden.com/blog/2011-07-24-frequency-counter-gen2/ Sun, 24 Jul 2011 17:07:24 +0000 https://swharden.com/blog/2011-07-24-frequency-counter-gen2/ I’m working to further simplify my frequency counter design. This one is simpler than my previous design both in hardware and software! Here’s a video to demonstrate the device in its current state: I utilize the ATMega48’s hardware counter which is synchronous with the system clock, so it can only measure frequency less than half of its clock speed. I solve this issue by dividing the input frequency by 8 and clocking the chip at 12mhz. https://swharden.com/blog/2011-07-16-half-hearted-diy-logic-analyzer-works-a-little/ Sat, 16 Jul 2011 22:52:17 +0000 https://swharden.com/blog/2011-07-16-half-hearted-diy-logic-analyzer-works-a-little/ While trying to attack the problem described in the previous entry, it became clear that a logic analyzer would be necessary. I thought I’d try to build one, and my first attempt was so close to being successful, but not quite there. It records 19 channels (the maximum pins available on the ATMega48 not being occupied by the status LED or USB connection pins) at a rate just under 1,000 samples per second. https://swharden.com/blog/2011-07-11-aj4vd-arsenal-recently-expanded/ Mon, 11 Jul 2011 17:02:33 +0000 https://swharden.com/blog/2011-07-11-aj4vd-arsenal-recently-expanded/ This is a multi-part blog entry added over 2 days of time documenting the progress of the addition of USB to a simple frequency counter. The final result lets me graph frequency over time on the computer, automatically, over days of time if desired. I’m quite pleased at the result, especially considering so little circuitry was required! It looks like this will be a multi-part blog entry. I’m in the process of figuring out how to add USB functionality to this simple device, which will be a fun way for me to express my creativity and think a bit outside the box while gaining some simple electrical engineering experience! https://swharden.com/blog/2011-07-09-sound-card-microcontrollerpc-communication/ Sat, 09 Jul 2011 23:30:44 +0000 https://swharden.com/blog/2011-07-09-sound-card-microcontrollerpc-communication/ _This page describes a method of sending data from a microchip to a PC using pulses of data. It’s an alternative to more traditional serial or USB methods of connectivity. It’s not intended as a solution for consumer products, but rather an easy hack for hobbyists to employ if they don’t have the equipment for other methods. This method doesn’t require any circuitry, just a sound card. The one built in your computer is fine, but I’m using a $1. https://swharden.com/blog/2011-07-08-create-mono-and-stereo-wave-files-with-python/ Fri, 08 Jul 2011 09:22:04 +0000 https://swharden.com/blog/2011-07-08-create-mono-and-stereo-wave-files-with-python/ My current project involves needing to create stereo audio in real time with Python. I’m using PyAudio to send the audio data to the sound card, but in this simple example I demonstrate how to create mono and stereo sounds with Python. I’m disappointed there aren’t good simple case examples on the internet, so I’m sharing my own. It doesn’t get much easier than this!

The chip I chose to use is an ATMega48. The ATMega 48 is $1.40 each in small quantities and comes crammed packed with features. The chip will be quite busy performing many functions, but its main loop will be executed at least every 50ms (required for USB, did I mention I’m bit-banging USB?!). I desire to have a bit of RTC (real time clock) functionality in that I need to precisely measure seconds, although I don’t need to actually know the time or date. https://swharden.com/blog/2011-06-05-permeability-tuned-oscillator-pto-working-nicely/ Sun, 05 Jun 2011 02:21:40 +0000 https://swharden.com/blog/2011-06-05-permeability-tuned-oscillator-pto-working-nicely/ My last entry described my accidental discovery of the PTO for QRP purposes. I breadboarded it and was amazed at the results! I went ahead and built this carefully in an enclosure and the output is wonderful. It’s strong, it’s stable, and it tunes effortlessly over the same range it did before (about 1MHz). The video describes details of the action, and demonstrates the stability of the oscillator by letting you hear it audibly on a nearby receiver. https://swharden.com/blog/2011-06-02-screwy-oscillator-idea/ Thu, 02 Jun 2011 21:18:47 +0000 https://swharden.com/blog/2011-06-02-screwy-oscillator-idea/ Can you believe it’s been almost 3 months since my last post? A lot’s been going on since then, namely the national board dental exam. I’m happy to report I prepared for it and performed above and beyond my expectations on the exam, and I’m quite satisfied. The last few weeks were quite a strain on my life in my aspects, and during that time I realized that I didn’t appreciate the little things (such as free time) that I would have loved to experience instead of studying. https://swharden.com/blog/2011-03-17-qrss-and-wspr-presentation-for-gars/ Thu, 17 Mar 2011 10:15:15 +0000 https://swharden.com/blog/2011-03-17-qrss-and-wspr-presentation-for-gars/ Last night I had the honor of speaking for GARS, the Gainesville Amateur Radio Society. Their club call (K4GNV) is used by the 146.820 MHz FM repeater (the most active in Gainesville). There were a few dozen attendees, and it was interesting to give a lecture on advanced radio topics to a body that had a lot of experience with RF. This group was a couple generations older and a lot more experienced and than the groups of students I’m used to speaking for! https://swharden.com/blog/2011-03-14-6-day-qrss-stitch/ Mon, 14 Mar 2011 16:10:10 +0000 https://swharden.com/blog/2011-03-14-6-day-qrss-stitch/ Has this been done before? I don’t know how useful it is, but I did it just for kicks and it turned out pretty cool. I realized that my strong signal (what is that?!) which is desentizing the the receiver is repetitive by day. Perhaps it’s something at the hospital! Days are 3/7/2011 through 3/12/2011, separated by black lines. Higher resolution image here: Cool stuff.

Simple, cheap, and absolutely useful! … and not to mention big green numbers which make it look more impressive than it actually is! This is my super-simple frequency counter designed to be used for amateur radio, all for about $10. It was a project I developed over the last few months and documented all along the way. It’s finished I guess, so this will probably be the last post about it! https://swharden.com/blog/2011-03-05-spring-break-qth/ Sat, 05 Mar 2011 17:40:56 +0000 https://swharden.com/blog/2011-03-05-spring-break-qth/ So here’s the deal: I’m staying in Orlando, FL at my parents’ home for a large portion of spring break. I wanted to take some radio equipment, and set up a simple antenna to allow me to operate. This post documents what I did, and only time will tell how well my configuration actually works! Let’s start with the video. It summarizes the antenna, and even shows me making my 1st contact with it to a guy in Vermont, and I’ve been getting good signal reports from Europe and South America as well. https://swharden.com/blog/2011-02-20-rf-workshop-launched/ Sun, 20 Feb 2011 00:13:37 +0000 https://swharden.com/blog/2011-02-20-rf-workshop-launched/ The Radio Active Workshop kicked off a couple weeks ago in the engineering department of the University of Florida led by yours truly! Jimmy Lin (an aerospace engineering graduate student) set up the group, and together we’re trying to provide an open environment for engineering students (or anyone who’s interested) to meet, share ideas, and get some practical hands-on experience building stuff. We made gave it a radio theme so it meshes nicely with the Gator Amateur Radio Club. https://swharden.com/blog/2011-02-12-wideband-receiver-works/ Sat, 12 Feb 2011 23:28:56 +0000 https://swharden.com/blog/2011-02-12-wideband-receiver-works/ I demonstrated earlier this week that I can generate a wide range of frequencies using a tank circuit and the oscillator in a SA612. I added a little circuitry and hooked the receiver to my homemade indoor 20m/40m dipole antenna and vwa la, audio emerges! Endless improvements can be made, but it demonstrates the functionality of this simple circuit. https://swharden.com/blog/2011-02-11-first-injections/ Fri, 11 Feb 2011 10:02:44 +0000 https://swharden.com/blog/2011-02-11-first-injections/ Yesterday was the notorious “injection lab” where 80 second-year dental students practice injecting on patients (classmates) for the first time. We all performed 5 injections blocking different nerves, some seemed more invasive than others. It was an interesting day I will probably remember. The photo is of my classmate (Steven) giving his first injection to me! Surprisingly it didn’t hurt as much as I expected. After the event I went to a GARC (Gator Amateur Radio Club) meeting and then to a workshop I’m helping lead in the engineering building. https://swharden.com/blog/2011-02-09-minimal-radio-project-continues/ Wed, 09 Feb 2011 00:18:26 +0000 https://swharden.com/blog/2011-02-09-minimal-radio-project-continues/ I got a big bag of fresh, new, copper clad PC board and I now wish I purchased a big pack months ago! Don’t laugh at me, but I was buying 4’‘x6’’ sheets of it at Radio Shack for about $5 a pop - ouch! I probably purchased 3 boards in my lifetime, but at that price you can imagine how careful I was not to use them. I soldered minimally to them, and only used them for the most important, established projects. https://swharden.com/blog/2011-02-04-frequency-counter-working/ Fri, 04 Feb 2011 21:26:26 +0000 https://swharden.com/blog/2011-02-04-frequency-counter-working/ I’m ecstatic! Finally I built something that worked the first time. Well… on the 3rd attempt! The goal was to develop a minimal-cost, minimal complexity frequency counter suitable for amateur radio. Although I think I can still cut cost by eliminating components and downgrading the microcontroller, I’m happy with my first working prototype. __I haven’t tested it rigorously __ with anything other than square waves, but I imagine that anything over 1PPV is sufficient (the input is through a bypass capacitor, internally biased right at the trigger threshold). https://swharden.com/blog/2011-02-03-prototype-radio-receiver-improving-daily/ Thu, 03 Feb 2011 23:16:55 +0000 https://swharden.com/blog/2011-02-03-prototype-radio-receiver-improving-daily/ This is the current state of my receiver. Unlike earlier designs this one uses NO VARIABLE CAPACITORS! This helps because (a) it reduces cost, (b) makes it easier to build for anyone (it’s hard to hunt down identical variable capacitors), and (c) allows it to be totally voltage controlled so microchip or PC control of frequency becomes trivial. Tuning over the entire 40m band is achieved with 3 LEDs reverse biased acting as varactors (wow! https://swharden.com/blog/2011-01-28-home-brew-transceiver-taking-shape/ Fri, 28 Jan 2011 14:13:33 +0000 https://swharden.com/blog/2011-01-28-home-brew-transceiver-taking-shape/ In the spirit of furthering my knowledge of AC circuity, I’m trying to build a 100% homebrew transceiver. Yeah, QRSS and ultra-weak signal, ultra-narrowband communications is still fun, but it’s not the same thrill as actually engaging in real time communication with somebody! My goal is a transmitter / receiver in a box. The basic features I desire are (1) multiple bands (at least 40m, 30m, 20m), (2) FULL-band coverage, (3) direct conversion receiver, (4) 10W transmitter, (5) digital frequency display, (6) common standard components (nothing mechanical, no air variable capacitors, everything must be easily obtainable on sites like Mouser and DigiKey), (7) SMT capability, (8) inexpensive ($20 is my goal, but that’s a tough goal! https://swharden.com/blog/2011-01-18-a-taste-of-culture/ Tue, 18 Jan 2011 20:47:01 +0000 https://swharden.com/blog/2011-01-18-a-taste-of-culture/ This blog has become too much about electronics. Yeah, electronics projects are good but there’s more to life than electronics! Right now I’m in dental school and… [pause] oh, yeah I don’t want to reflect on that. Let’s talk electronics! I keep planning to eventually write what dental school is like from an honest perspective for its archival significance, but the thought of spending time writing about dental school makes my gut churn. https://swharden.com/blog/2011-01-16-first-homebrew-qso-ever/ Sun, 16 Jan 2011 18:39:32 +0000 https://swharden.com/blog/2011-01-16-first-homebrew-qso-ever/ Today is a very special day, as it’s the day I first made a contact with a radio transmitter I built completely on my own! The plans were copied from no where (although the concepts were obviously learned elsewhere), so it’s somewhat of a unique design (likely because it’s not very good!). I’ll be the first to admit there is MUCH room for improvement, but my goal was to design and build a multi-band transmitter which would produce RF (not necessarily efficiently) at multiple bands by dropping in crystals of different frequencies. https://swharden.com/blog/2011-01-10-40m-junkbox-qrp-transmitter/ Mon, 10 Jan 2011 09:01:20 +0000 https://swharden.com/blog/2011-01-10-40m-junkbox-qrp-transmitter/ I decided to sit down and build something last night, and I’m surprised by how functional it is! Nothing about it is extraordinarily complex, and it’s extremely flexible, accommodating almost any crystal you want to drop in. Although I doubt I’ll use this exact design for a permanent transmitter, it was fun to build and I’ll post photos hoping to inspire others to tinker with RF circuitry as well! The final device worked on 7. https://swharden.com/blog/2010-12-28-full-auto-rapidfire-mouse-modification/ Tue, 28 Dec 2010 01:52:09 +0000 https://swharden.com/blog/2010-12-28-full-auto-rapidfire-mouse-modification/ I did this purely for the fun of it, and am aware there are many ways to accomplish the same thing. I was playing Counter Strike Source (you should buy it and play with me, name “swharden”) and my fingers are really cold from the winter weather, and wondered if I could have a button help with the rapid firing of pistols. I mentioned it on the microphone, and one of the players ("{Ẋpli¢it} shadow") said I should go for it. https://swharden.com/blog/2010-11-29-my-simple-balcony-antenna/ Mon, 29 Nov 2010 14:04:54 +0000 https://swharden.com/blog/2010-11-29-my-simple-balcony-antenna/ I’ve been using a new HF antenna recently with surprisingly good results. Hopefully this page will be encouraging to those in apartments with severe antenna restrictions. I used to operate an indoor dipole mounted on my ceiling which was virtually invisible, but ever since solar panels were added to my apartment roof this antenna is picking up a huge amount of noise. In the past I played with a base-loaded vertical antenna made from copper pipe and it worked okay, especially when on my balcony, but it was bulkier than needed and awkward to store. https://swharden.com/blog/2010-11-28-crystal-oven-experiments/ Sun, 28 Nov 2010 17:06:18 +0000 https://swharden.com/blog/2010-11-28-crystal-oven-experiments/ Now that I’ve finished my 6-channel data logger (previous post), it’s time to put it to the test! I’m using a handful of LM335 temperature sensors to measure temperature, and a 20 Ohm resistor to act as a heater. When 1A of current passes through it, it gets quite toasty! First, I’ll make some temperature probes… UPDATE: Those photos show a partially completed sensor. Obviously the third wire is required between the resistor and the LM335 to allow for measurement! https://swharden.com/blog/2010-11-24-serial-port-temperature-measurement/ Wed, 24 Nov 2010 08:17:03 +0000 https://swharden.com/blog/2010-11-24-serial-port-temperature-measurement/ While working to perfect my temperature-controlled manned experimental propagation transmitter (MEPT), I developed the need to accurately measure temperature inside my Styrofoam enclosure (to assess drift) and compare it to external temperature (to assess insulation effects). I accomplished this utilizing the 8 ADC channels of the ATMega48 and used its in-chip USART capabilities to send this data to a PC for logging. I chose the ATMega48 over the ATTiny2313 (which has USART but no ADCs) and the ATTiny44a (which has ADCs but no USART). https://swharden.com/blog/2010-11-14-improved-mept-enclosure/ Sun, 14 Nov 2010 20:22:38 +0000 https://swharden.com/blog/2010-11-14-improved-mept-enclosure/ I’ve been pretty busy lately, but I drip to the hardware store with the XYL produced a PVC enclosure that looked perfect for my ongoing MEPT (manned experimental propagation transmitter) projects. I didn’t want to buy it (it was a little pricey by my standards, at $6 USD, which is about the total cost of the transmitter!) but the wife convinced me and I’m glad she did! I intended it to replace the styrofoam enclosure I had been using, but I wasn’t thinking clearly and drilled holes in the box and mounted screws through them. https://swharden.com/blog/2010-11-11-deciphering-qr-code-from-radio-spectrograph/ Thu, 11 Nov 2010 15:13:29 +0000 https://swharden.com/blog/2010-11-11-deciphering-qr-code-from-radio-spectrograph/ Although I’ve been ridiculously busy the last few weeks, I’ve been eying some posts circulating around the Knights QRSS mailing list regarding mysterious signals in the 40m band. They recognized it as a QR Code and tried decoding it with phones and such, but the signal wasn’t strong enough above the noise to be automatically deciphered. That’s the original spectrograph as captured by ON5EX in Belgium. It’s a pretty good capture, it’s just not great enough to be automatically decoded. https://swharden.com/blog/2010-09-17-climbing-a-1786-foot-tall-tower/ Fri, 17 Sep 2010 08:40:38 +0000 https://swharden.com/blog/2010-09-17-climbing-a-1786-foot-tall-tower/ When I saw this, I had to share it. … and no, that’s not me! https://swharden.com/blog/2010-09-10-cutting-edge-1960s-oscilloscope-for-the-70s/ Fri, 10 Sep 2010 22:33:26 +0000 https://swharden.com/blog/2010-09-10-cutting-edge-1960s-oscilloscope-for-the-70s/ I’m extremely excited about my new purchase! I found this on Craigslist of all places! It’s a Tektronix 453 oscilloscope from the late 60s in pretty good condition. I’m not going into a bunch of technical details about what I’m using it for, but let’s just say I’m satisfied. The 1khz square wave generator doesn’t function and one of the lights is not working, but other than that it seems to be fine. https://swharden.com/blog/2010-09-09-quantifying-university-network-frustrations/ Thu, 09 Sep 2010 08:06:39 +0000 https://swharden.com/blog/2010-09-09-quantifying-university-network-frustrations/ I’m sitting in class frustrated as could be. The Internet in this room is unbelievably annoying. For some reason, everything runs fine, then functionality drops to unusable levels. Downloading files (i.e., PDFs of lectures) occurs at about 0.5kb/s (wow), and Internet browsing is hopeless. At most, I can connect to IRC and enjoy myself in #electronics, #python, and #linux. I decided to channel my frustration into productivity, and wrote a quick Python script to let me visualize the problem. https://swharden.com/blog/2010-09-07-ultra-simple-way-to-send-data-from-any-microcontroller-to-a-pcs-serial-port/ Tue, 07 Sep 2010 08:37:13 +0000 https://swharden.com/blog/2010-09-07-ultra-simple-way-to-send-data-from-any-microcontroller-to-a-pcs-serial-port/ This weekend I had a need, and I met it with parts I had on hand. Simply put, I wanted to assess whether or not my temperature-controlled crystal heater is doing its job in keeping temperature rock-stable. I wanted to measure temperature by measuring the ADC (analog-to-digital) value at the middle of a voltage divider with a resistor and a thermistor. Using a computer to plot this data, I can see if temperature fluctuates as my apartment AC turns on/off, or if it’s perfectly stable (my goal). https://swharden.com/blog/2010-09-04-vd-labs-makes-it-big-debut/ Sat, 04 Sep 2010 22:36:51 +0000 https://swharden.com/blog/2010-09-04-vd-labs-makes-it-big-debut/ The VD Labs web page has been published! I hope that the new VD Labs page will be a single location where I can link to descriptions and downloads of useful radio, audio analysis, and QRSS-related software. It will eventually be the home of the next (recorded-from-scratch) version of QRSS VD, but let’s not get too far ahead of ourselves! Since I ran out of steam from working so much on QRSS VD, I didn’t think I’d be publishing mush more “useful” software, but this one blind-sighted me. https://swharden.com/blog/2010-08-27-hacking-together-a-crystal-oven-part-2/ Fri, 27 Aug 2010 19:21:25 +0000 https://swharden.com/blog/2010-08-27-hacking-together-a-crystal-oven-part-2/ With the last post’s promising results, I set out to finish my crystal oven prototype and affix it to my QRSS MEPT prototype. If everything works well, I’m ready to publish the final schematic and parts lists! (and make several MEPTs for people who were interested in having one). I’m not confident my approach to the heater was the best, and am already thinking of ways I could have improved on its performance, but I think this just might work! https://swharden.com/blog/2010-08-26-minimalist-crystal-oven/ Thu, 26 Aug 2010 10:40:16 +0000 https://swharden.com/blog/2010-08-26-minimalist-crystal-oven/ So I’m working on building a crystal oven to keep my QRSS MEPT (radio transmitter) at an extremely stable frequency. Even inside a thick Styrofoam box, slight changes in my apartment temperature caused by the AC turning on and off is enough to change the crystal temperature of the transmitter, slightly modifying its oscillation frequency. For a device that vibrates exactly 10,140,070 times a second, even 3 to many or too few vibrations per second is too much. https://swharden.com/blog/2010-08-24-lost-project-revisited-on-hackaday/ Tue, 24 Aug 2010 21:22:37 +0000 https://swharden.com/blog/2010-08-24-lost-project-revisited-on-hackaday/ I somehow forgot about a cool project I made over a year ago! I guess dental school got in the way of my productivity. It’s a little ironic how the last post was about something I made a year ago screwing up, and this one is about something I made a year ago turning out well! Anyhow, the world’s only battery powered microcontroller based handheld prime number generator I made last year (documented here) got some new exposure this morning when it was posted on HackADay. https://swharden.com/blog/2010-08-15-tooth-as-a-radio-receiver-part-1/ Sun, 15 Aug 2010 12:13:39 +0000 https://swharden.com/blog/2010-08-15-tooth-as-a-radio-receiver-part-1/ We’ve all heard the urban legend where someone’s tooth filling picks up radio signals, some versions claim AM radio stations’ music is heard, others that wartime Morse code is heard. Is this really possible? Well, as a dental student and an electrical engineering / RF engineering enthusiast, I can think of no one better prepared to put this myth to the test! Yeah, I’m going to put my money where my mouth is. https://swharden.com/blog/2010-08-11-epic-failure-1-year-in-the-making/ Wed, 11 Aug 2010 07:49:58 +0000 https://swharden.com/blog/2010-08-11-epic-failure-1-year-in-the-making/ My expression is completely flat right now. I simply cannot believe I’m about to say what I’m preparing to say. I spent nearly a year cracking large prime numbers. In short, I took-on a project I called _The Flowering N’th Prime Project, where I used my SheevaPlug to generate a list of every [every millionth] prime number. The current “golden standard” is this page where one can look-up the N’th prime up to 1 trillion. https://swharden.com/blog/2010-08-09-converting-numbers-to-morse-code-with-gcc/ Mon, 09 Aug 2010 07:55:47 +0000 https://swharden.com/blog/2010-08-09-converting-numbers-to-morse-code-with-gcc/ One of my microcontroller projects requires me to measure values and transmit then in Morse code. There may be code out there to do this already, but I couldn’t find it. I’m sure there are more elegant and efficient ways to handle the conversion, but this works for me. Hopefully someone will find it useful! #include <stdio.h> //Morse code numbers from 0 to 9 char *array[10] = {"-----", ".----", "..---", ". https://swharden.com/blog/2010-07-22-idea-vdfsk-modulation/ Thu, 22 Jul 2010 12:39:54 +0000 https://swharden.com/blog/2010-07-22-idea-vdfsk-modulation/ My goal is to create a QRPP (extremely low power) transmitter and modulation method to send QRSS (extremely slow, frequency shifting data) efficiently, able to be decoded visually or with automated image analysis software. This evolving post will document the thought process and development behind my Frequency Shift Keying method, vdFSK. Briefly, this is what my idea is. Rather than standard 2-frequencies (low for space, high for tone) QRSS3 (3 seconds per dot), I eliminate the need for pauses between dots by using 3 frequencies (low for a space between letters, medium for dot, high for dash). https://swharden.com/blog/2010-07-14-high-altitude-balloon-transmitter/ Wed, 14 Jul 2010 08:05:46 +0000 https://swharden.com/blog/2010-07-14-high-altitude-balloon-transmitter/ SUMMARY: A small group of high school students taking an AP class for college credit launched a high-altitude weather balloon with a small payload. In addition to a video transmitter and GPS transmitter, they decided to include a simple transmitter built from scratch. This is the story of the project, with emphasis on the simple transmitter's design, construction, implementation, and reception (which surprised me, being detected ~200 miles away and lasting the entire duration of the flight! https://swharden.com/blog/2010-07-12-coders-block/ Mon, 12 Jul 2010 22:36:03 +0000 https://swharden.com/blog/2010-07-12-coders-block/ I like the idea of writing a set of tools for scientific frequency analysis (more than just turning audio into images), and I keep starting over re-coding things from scratch. I develop too much, too quickly, and half way in I get overwhelmed and mentally blocked. I do it to myself. I’ve taken about a week off and will continue to take a few more days off to reset my mind. https://swharden.com/blog/2010-06-28-fighting-to-make-gtk-glade-and-python-play-in-windows/ Mon, 28 Jun 2010 09:46:26 +0000 https://swharden.com/blog/2010-06-28-fighting-to-make-gtk-glade-and-python-play-in-windows/ These screenshots show me running the Py2EXE-compiled script I wrote last weekend on a Windows 7 machine. Additionally there is a screenshot of the “Add/Remove Programs” window demonstrating which versions of which libraries were required. https://swharden.com/blog/2010-06-27-python-script-with-gtk-gui-compiled-with-py2exe/ Sun, 27 Jun 2010 23:16:05 +0000 https://swharden.com/blog/2010-06-27-python-script-with-gtk-gui-compiled-with-py2exe/ This is a total hack, but it works. I spent all night jumping through hoops to get this thing to run on Windows. The problem is that I designed my previous UI in a version of GLADE which is newer than that supported by Windows. It looks like it’s not backward-compatible, so I have to re-design the GUI from scratch using an earlier version of GLADE. I’ll probably stick to GTK version 2. https://swharden.com/blog/2010-06-26-spectrograph-ui-made-with-glade/ Sat, 26 Jun 2010 19:03:05 +0000 https://swharden.com/blog/2010-06-26-spectrograph-ui-made-with-glade/ While continuing to investigate my options for the new version of QRSS VD, I re-visited Glade, the GTK GUI designer. In short, it lets you draw widgets (combo boxes, scrollbars, labels, images, buttons, etc) onto windows and then makes it easy to add code to the GUI. I *hated* the old QRSS VD development because of the ridiculously large amount of time I had to spend coding the UI. Hopefully by migrating from TKinter to GTK - while it opens a whole new can of worms - will let me add functionality rapidly without hesitation. https://swharden.com/blog/2010-06-24-fast-tk-pixelmap-generation-from-2d-numpy-arrays-in-python/ Thu, 24 Jun 2010 21:29:29 +0000 https://swharden.com/blog/2010-06-24-fast-tk-pixelmap-generation-from-2d-numpy-arrays-in-python/ I had TKinter all wrong! While my initial tests with PyGame’s rapid ability to render Numpy arrays in the form of pixel maps proved impressive, it was only because I was comparing it to poor TK code. I don’t know what I was doing wrong, but when I decided to give TKinter one more shot I was blown away – it’s as smooth or smoother as PyGame. Forget PyGame! I’m rendering everything in raw TK from now on. https://swharden.com/blog/2010-06-24-detrending-data-in-python-with-numpy/ Thu, 24 Jun 2010 08:38:52 +0000 https://swharden.com/blog/2010-06-24-detrending-data-in-python-with-numpy/ ⚠️ SEE UPDATED POST: Signal Filtering in Python While continuing my quest into the world of linear data analysis and signal processing, I came to a point where I wanted to emphasize variations in FFT traces. While I am keeping my original data for scientific reference, visually I want to represent it emphasizing variations rather than concentrating on trends. I wrote a detrending function which I’m sure will be useful for many applications: https://swharden.com/blog/2010-06-23-insights-into-ffts-imaginary-numbers-and-accurate-spectrographs/ Wed, 23 Jun 2010 22:21:00 +0000 https://swharden.com/blog/2010-06-23-insights-into-ffts-imaginary-numbers-and-accurate-spectrographs/ I’m attempting to thoroughly re-write the data assessment portions of my QRSS VD software, and rather than rushing to code it (like I did last time) I’m working hard on every step trying to optimize the code. I came across some notes I made about Fast Fourier Transformations from the first time I coded the software, and though I’d post some code I found helpful. Of particular satisfaction is an email I received from Alberto, I2PHD, the creator of Argo (the “gold standard” QRSS spectrograph software for Windows). https://swharden.com/blog/2010-06-20-smoothing-window-data-averaging-in-python-moving-triangle-tecnique/ Sun, 20 Jun 2010 22:12:03 +0000 https://swharden.com/blog/2010-06-20-smoothing-window-data-averaging-in-python-moving-triangle-tecnique/ ⚠️ SEE UPDATED POST: Signal Filtering in Python While I wrote a pervious post on linear data smoothing with python, those scripts were never fully polished. Fred (KJ4LFJ) asked me about this today and I felt bad I had nothing to send him. While I might add that the script below isn’t polished, at least it’s clean. I’ve been using this method for all of my smoothing recently. Funny enough, none of my code was clean enough to copy and paste, so I wrote this from scratch tonight. https://swharden.com/blog/2010-06-19-simple-python-spectrograph-with-pygame/ Sat, 19 Jun 2010 21:53:25 +0000 https://swharden.com/blog/2010-06-19-simple-python-spectrograph-with-pygame/ While thinking of ways to improve my QRSS VD high-definitions spectrograph software, I often wish I had a better way to display large spectrographs. Currently I’m using PIL (the Python Imaging Library) with TK and it’s slow as heck. I looked into the PyGame project, and it seems to be designed with speed in mind. I whipped-up this quick demo, and it’s a simple case audio spectrograph which takes in audio from your sound card and graphs it time vs. https://swharden.com/blog/2010-06-15-simplest-case-pygame-example/ Tue, 15 Jun 2010 08:29:03 +0000 https://swharden.com/blog/2010-06-15-simplest-case-pygame-example/ I’m starting to investigate PyGame as an alternative to PIL and K for my QRSS VD spectrograph project. This sample code makes a box bounce around a window. import pygame, sys pygame.init() #load pygame modules size = width, height = 320, 240 #size of window speed = [2, 2] #speed and direction screen = pygame.display.set_mode(size) #make window s=pygame.Surface((100,50)) #create surface 100px by 50px s.fill((33,66,99)) #color the surface blue r=s.get_rect() #get the rectangle bounds for the surface clock=pygame. https://swharden.com/blog/2010-06-12-insulated-mept-stable-signal/ Sat, 12 Jun 2010 09:18:14 +0000 https://swharden.com/blog/2010-06-12-insulated-mept-stable-signal/ While it may not be perfect, it’s a whole lot better. Below is a capture from this morning of my signal (the waves near the bottom). Compare that to how it was before and you should notice a dramatic improvement! The MEPT is inside a metal box inside a 1-inch-thick Styrofoam box. Very cool! https://swharden.com/blog/2010-06-11-failing-o-scope-bah/ Fri, 11 Jun 2010 17:12:36 +0000 https://swharden.com/blog/2010-06-11-failing-o-scope-bah/ My oscilloscope decided to die on my right as I finally was able to view my 10 MHz waveform. I used a piece of coax with a load at the connector to the o-scope, and ran the coax to my test points. It was beautiful! … and lasted about 30 seconds. The culprit seems to be a failing “focus” knob. My images had been getting blurrier by the day, and now it’s completely black unless I twist pretty hard on the focus knob. https://swharden.com/blog/2010-06-10-qrss-receiver-works-barely/ Thu, 10 Jun 2010 23:27:40 +0000 https://swharden.com/blog/2010-06-10-qrss-receiver-works-barely/ I completed work on my first RF receiver, and for what it is it seems to work decently. It should be self-explanatory from the photos. It’s based around an SA602. As with everything, I don’t plan on posting schematics until the project is complete because I don’t want people re-creating junky circuits! It’s stationed at the University of Florida’s club station W4DFU and its spectrograph can be viewed in real time from the QRSS VD - Web Grabber - W4DFU page. https://swharden.com/blog/2010-06-09-minimalist-radio-receiver/ Wed, 09 Jun 2010 23:42:00 +0000 https://swharden.com/blog/2010-06-09-minimalist-radio-receiver/ Now that my minimalist QRSS transmitter is mostly functional, I’m shifting gears toward building a minimalist receiver. These are some early tests, but I’m amazed I managed to hack something together that actually works! Once it’s finished I’ll post schematics. For now, here are some photos. This receiver is based upon an SA602 and although there *IS* an op-amp on the board, I actually bypassed it completely! The SA602 seems to put out enough juice to make my PC microphone jack happy, and those cheap op-amps are noisy anyway, so awesome! https://swharden.com/blog/2010-06-07-qrss-vd-image-assembler/ Mon, 07 Jun 2010 23:20:18 +0000 https://swharden.com/blog/2010-06-07-qrss-vd-image-assembler/ This minimal Python script will convert a directory filled with tiny image captures such as this into gorgeous montages as seen below!

My o-scope’s backlight hasn’t worked since I got it (for $10), so I soldered-up a row of 9 orange LEDs (I had them in a big bag) and hooked them directly up to a 3v wall wart. In retrospect I wish I had a bunch of blue LEDs… but for now I can’t get over how well this worked! Compare it to the images a few posts back - you can really see the grid lines now! https://swharden.com/blog/2010-05-28-aj4vd-gator-spotted-in-essex-england/ Fri, 28 May 2010 19:31:10 +0000 https://swharden.com/blog/2010-05-28-aj4vd-gator-spotted-in-essex-england/ It’s so awesome that such a small device can send such a low power signal so far away! Anyhow, the title says it all. Special thanks to G6AVK’s “part time” grabber for capturing this awesome series. That’s a 4356.4 mile trip on USB power! ha! https://swharden.com/blog/2010-05-27-aj4vd-gator-chomps-its-way-into-belgium/ Thu, 27 May 2010 21:38:03 +0000 https://swharden.com/blog/2010-05-27-aj4vd-gator-chomps-its-way-into-belgium/ Yeah, that’s over 4,500 miles away! The following image was captured from ON5EX’s QRSS grabber in Belgium! Amazing. I don’t have the equipment to measure its power output, but it’s running on USB power and I’d assume it’s putting out less than 100mW. Very cool! https://swharden.com/blog/2010-05-27-aj4vd-gator-spotted-in-ma/ Thu, 27 May 2010 11:24:17 +0000 https://swharden.com/blog/2010-05-27-aj4vd-gator-spotted-in-ma/ That’s over 1,00 miles on a few milliwatts! The transmitter is the ridiculously simple one pictured below. I’m blown away! It was seen on running QRSS VD software! Awesome!! https://swharden.com/blog/2010-05-26-pushing-and-pulling/ Wed, 26 May 2010 07:42:39 +0000 https://swharden.com/blog/2010-05-26-pushing-and-pulling/ I found a way to quadruple the output power of my QRSS transmitter without changing its input parameters. Thanks to a bunch of people (most of whom are on the Knights QRSS mailing list) I decided to go with a push-pull configuration using 2 pairs of 4 gates (8 total) of a 74HC240. I’ll post circuit diagrams when I perfect it, but for now check out these waveforms! First of all, this is the waveform before and after amplification with the 74HC240. https://swharden.com/blog/2010-05-24-solar-powered-qrss-beacon/ Mon, 24 May 2010 07:47:01 +0000 https://swharden.com/blog/2010-05-24-solar-powered-qrss-beacon/ Haray! I’m making awesome progress with my QRSS transmitter design. Because my current transmitter (previous few posts) was randomly freezing-up (likely due to the oscillator stopping its oscillating due to being overloaded) so I moved the oscillator from in-chip to an external oscillator. It’s been made small enough to fit in an Altoids tin, and I already tested it with the solar panel and it works! Awesome! Here are some photos. https://swharden.com/blog/2010-05-22-first-qrss-spot/ Sat, 22 May 2010 22:47:03 +0000 https://swharden.com/blog/2010-05-22-first-qrss-spot/ I’m so excited! This little transmitter I made and programmed to transmit my call sign (AJ4VD) and a picture of a gator got its first spotting tonight! I’m so excited. It was reported by W4HBK in Pensacola, FL. It’s only 300 miles away, but it’s a start! I’m keeping my fingers crossed and maybe someday soon I’ll hear from Europe. https://swharden.com/blog/2010-05-22-debut-of-the-aj4vd-qrss-gator/ Sat, 22 May 2010 18:41:54 +0000 https://swharden.com/blog/2010-05-22-debut-of-the-aj4vd-qrss-gator/ I re-wrote the code from the previous entry to do several things. Once of which was to make a gator rather than a fish. It’s more appropriate since I’m planning on housing the transmitter at the University of Florida. To do it, I drew a gator in paint and wrote a python script to convert the image into a series of points. I’ll post it later. One thing to note was that size was a SERIOUS issue. https://swharden.com/blog/2010-05-19-debut-of-the-aj4vd-qrss-fish/ Wed, 19 May 2010 19:58:16 +0000 https://swharden.com/blog/2010-05-19-debut-of-the-aj4vd-qrss-fish/ Finally! After a few years tumbling around in my head, a few months of reading-up on the subject, a few weeks of coding, a few days of bread-boarding, a few hours of building, a few minutes of soldering, and a few seconds of testing I’ve finally done it - I’ve created my first QRSS transmitter! I’ll describe it in more detail once I finalize the design, but for now an awesome working model. https://swharden.com/blog/2010-05-17-simplest-qrss-transmitter-ever/ Mon, 17 May 2010 11:13:52 +0000 https://swharden.com/blog/2010-05-17-simplest-qrss-transmitter-ever/ Success! Amid a bunch of academic exams, psycho-motor tests, and other crazy shenanigans my dental school is putting me through, I managed to do something truly productive! I built a simple QRSS transmitter with an ATTiny44A microcontroller clocked by a 7.04 MHz crystal which generates FSK signals and modulates its own frequency by applying potential to a reverse-biased diode at the base of the crystal, the output (CKOUT) of which is amplified by an octal buffer and sent out through an antenna. https://swharden.com/blog/2010-05-10-generate-luts-with-python/ Mon, 10 May 2010 22:31:46 +0000 https://swharden.com/blog/2010-05-10-generate-luts-with-python/ I wrote a script to generate and display LUTs with Python. There has been a lot of heated discussion in the QRSS Knights mailing list as to the use of color maps when representing QRSS data. I’ll make a separate post (perhaps later?) documenting why it’s so critical to use particular mathematically-generated color maps rather than empirical “looks good to me” color selections. Anyway, this is what I came up with: https://swharden.com/blog/2010-04-27-rachmaninoffs-bookmarklets/ Tue, 27 Apr 2010 22:09:04 +0000 https://swharden.com/blog/2010-04-27-rachmaninoffs-bookmarklets/ What a hodgepodge of topics my life has become. Yeah, dental school has been rough lately (finals week was last week), but I’m hanging in there and trying to be creative nonetheless. I’ve been dabbling in video motion tracking last week, and am contemplating attacking a project involving a lot of video shooting/editing and possibly some 3D work. It must have been almost 10 years since I last used 3D modeling software! https://swharden.com/blog/2010-04-03-microcontroller-clocking-a-transmitter/ Sat, 03 Apr 2010 23:19:37 +0000 https://swharden.com/blog/2010-04-03-microcontroller-clocking-a-transmitter/ __I shouldn’t claim this idea as novel. __After googling around, I found another person who’s doing the same thing, and now that I read his page I remember reading his page before, which is likely where I got the idea in the first place. I want to give him credit and hope that my project can turn out successfully like his! http://clayton.isnotcrazy.com/mept_v1. __Here’s my idea: __ The core of any transmitter is an oscillator, and in simple transmitters (like QRSS devices), it’s often a crystal. https://swharden.com/blog/2010-03-20-impeeded-progress/ Sat, 20 Mar 2010 16:53:11 +0000 https://swharden.com/blog/2010-03-20-impeeded-progress/ Spring break is over and dental school classes have resumed. An unexpected side-effect of spending all of spring break working so hard on my QRSS VD software project is that when I resumed dental school, I actually feel more relaxed. It’s like spring break was my period of intense work, and the rest of dental school is my “break”. It makes me a little disappointed though - I feel like dental school isn’t pushing me very hard, and I don’t feel like I’m learning or growing like I could be. https://swharden.com/blog/2010-03-16-w4dfu-gator-seen-in-canada/ Tue, 16 Mar 2010 12:29:29 +0000 https://swharden.com/blog/2010-03-16-w4dfu-gator-seen-in-canada/ I don’t have long, but the picture speaks for itself.

So far I’ve made a few dozen contacts in Morse code with my humble little setup (~20 watts of power, direct conversion receiver, indoor homemade antenna). The photo shows some QSL cards I’ve gotten. Anyhow, my apartment manager decided that my apartment needed to have solar panels added to it. https://swharden.com/blog/2010-03-09-captured-overseas/ Tue, 09 Mar 2010 18:01:16 +0000 https://swharden.com/blog/2010-03-09-captured-overseas/ While working on the spectrograph software I’m trying to complete this spring break, I happened to capture a cool signal from Italy. IW4DXW was sending some cool signals that I captured around 10.140 MHz. See how his call sign is written “visually” on the spectrogram? I thought I’d post it because it’s an encouraging sign that my software is going in the right direction. Also note the numerous QRSS FSK signals around it! https://swharden.com/blog/2010-03-07-dynamic-image-generation-with-python/ Sun, 07 Mar 2010 18:47:00 +0000 https://swharden.com/blog/2010-03-07-dynamic-image-generation-with-python/ I’m working on a software project and I’d love the startup screen to be unique. I want the splash image to be generated programmatically. I have to generate it from the script, but how can I reliably print text on an image with fonts vary across operating systems? Keep in mind many OS’s don’t have “arial.ttf”, or no truetype fonts at all! First, I created a 2D binary array to represent the alphabet using pixel fonts such as this as a reference. https://swharden.com/blog/2010-03-06-brewing-excitement/ Sat, 06 Mar 2010 23:49:08 +0000 https://swharden.com/blog/2010-03-06-brewing-excitement/ Wow, I can’t believe I took-on such a massive challenge this week! Ironically I’ve worked harder and learned more in the last 4 days than I have over the last 9 months of dental school. This is an incredible feeling of accomplishment. My program, coded from scratch, polls the sound card continuously and makes extremely large spectrographs. It’s not finished, but it’s working. I’m impressed! The image above is the actual-size display of the image below. https://swharden.com/blog/2010-03-05-animated-realtime-spectrograph-with-scrolling-waterfall-display-in-python/ Fri, 05 Mar 2010 22:51:21 +0000 https://swharden.com/blog/2010-03-05-animated-realtime-spectrograph-with-scrolling-waterfall-display-in-python/ My project is coming along nicely. This isn’t an incredibly robust spectrograph program, but it sure gets the job done quickly and easily. The code below will produce a real time scrolling spectrograph entirely with Python! It polls the microphone (or default recording device), should work on any OS, and can be adjusted for vertical resolution / FFT frequency discretion resolution. It has some simple functions for filtering (check out the de-trend filter! https://swharden.com/blog/2010-03-05-realtime-fft-graph-of-audio-wav-file-or-microphone-input-with-python-scipy-and-wckgraph/ Fri, 05 Mar 2010 16:30:37 +0000 https://swharden.com/blog/2010-03-05-realtime-fft-graph-of-audio-wav-file-or-microphone-input-with-python-scipy-and-wckgraph/ I’m stretching the limits of what these software platforms were designed to to, but I’m impressed such a hacked-together code produces fast, functional results. The code below is the simplest case code I could create which graphs the audio spectrum of the microphone input. It seems to run fine with about 30+ FPS on my modest machine. It should work on Windows and Linux. I chose not to go with matplotlib because I didn’t think it was fast enough for my needs in this one case. https://swharden.com/blog/2010-03-05-smoothly-scroll-an-image-across-a-window-with-tkinter-vs-pygame/ Fri, 05 Mar 2010 08:49:00 +0000 https://swharden.com/blog/2010-03-05-smoothly-scroll-an-image-across-a-window-with-tkinter-vs-pygame/ The goal is simple: have a very large image (larger than the window) automatically scroll across a Python-generated GUI window. I already have the code created to generate spectrograph images in real time, now I just need a way to have them displayed in real time. At first I tried moving the coordinates of my images and even generating new images with create_image(), but everything I did resulted in a tacky “flickering” effect (not to mention it was slow). https://swharden.com/blog/2010-03-03-viewing-large-images-with-scrollbars-using-python-tk-and-pil/ Wed, 03 Mar 2010 19:56:55 +0000 https://swharden.com/blog/2010-03-03-viewing-large-images-with-scrollbars-using-python-tk-and-pil/ __I wrote a program to display extremely large images in Python using TK. __It’s interesting how simple this program is, yet frustrating how long it took me to figure out. This little Python program will load an image (pretty much any format) using the Python Imaging Library (PIL, which must be installed) and allows you to see it on a scrollable canvas (in two directions) with Tkinter and ImageTk. The above screenshot is of the program viewing the image below: https://swharden.com/blog/2010-02-07-simple-diy-stealth-apartment-antenna-for-20m-and-40m/ Sun, 07 Feb 2010 17:49:49 +0000 https://swharden.com/blog/2010-02-07-simple-diy-stealth-apartment-antenna-for-20m-and-40m/ I don’t want to spend lots of money for a HF antenna, and even if I did my apartment complex wouldn’t allow it! This is my story, and while I’m no expert I hope that sharing my experience will help encourage others to try crazy things in the spirit of invention. A friend loaned me a Century 21 HF CW-only transceiver which puts out ~20W. As far as an antenna, I was limited to what I could build. https://swharden.com/blog/2010-02-02-converting-ascii-text-to-cw-morse-code-with-linux/ Tue, 02 Feb 2010 10:58:54 +0000 https://swharden.com/blog/2010-02-02-converting-ascii-text-to-cw-morse-code-with-linux/ I wanted a way to have a bunch of Morse code mp3s on my mp3 player (with a WPM/speed that I decide and I found an easy way to do it with Linux. Rather than downloading existing mp3s of boring text, I wanted to be able to turn ANY text into Morse code, so I could copy something interesting (perhaps the news? hackaday? bash.org?). It’s a little devious, but my plan is to practice copying Morse code during class when lectures become monotonous. https://swharden.com/blog/2010-01-30-rainy-mornings-and-boring-bicuspids/ Sat, 30 Jan 2010 13:41:59 +0000 https://swharden.com/blog/2010-01-30-rainy-mornings-and-boring-bicuspids/ Dental school is taking a lot of time away from me. I try my best to compartmentalize dental school into a chunk of my schedule (a massive chunk), trying to use the rest of the time to spend with my family (wife) and when she’s at work work on electronics (which seems to be radio these days). A few weeks ago I took the final amateur radio license exam and received my Amateur Extra license. https://swharden.com/blog/2010-01-01-cej-qrss-and-life-recontemplation/ Fri, 01 Jan 2010 18:33:50 +0000 https://swharden.com/blog/2010-01-01-cej-qrss-and-life-recontemplation/ QRSS uses extremely simple radio transmitters at extremely low power to send an extremely slow Morse code message over an extremely large distance to extremely sensitive receivers which are extremely dependent on computers to decode. While you might be able to send a voice message across the ocean with ~100 watts of power, there are people sending messages with milliwatts! The main idea is that if you send the signals slow enough, and average the audio data (fast Fourier transformation) over a long enough time, weak signals below the noise threshold will stand out enough to be copied visually. https://swharden.com/blog/2009-12-10-hf-cw-on-the-cheap/ Thu, 10 Dec 2009 23:44:15 +0000 https://swharden.com/blog/2009-12-10-hf-cw-on-the-cheap/ This is a project I intend to work on over Christmas break. I’m wondering if I can make a simple HF transceiver capable of working any HF band by driving a Pixie II CW transceiver with a SI 570 digital programmable oscillator. Here’s what my pixie II sounds like on 80m.mp3 and 40m.mp3 with a strong antenna. Preliminary work demonstrates a functional receiver powered by a crystal. I don’t think the currently-configured digital oscillator is putting out enough power to run the circuit, but it’ll take more time to get that up and running. https://swharden.com/blog/2009-12-05-dental-school-is-boring/ Sat, 05 Dec 2009 21:00:00 +0000 https://swharden.com/blog/2009-12-05-dental-school-is-boring/ This is an AI Generated Summary Many of the blog posts I wrote when I was young are no longer available on this website.

Today I propose a semi-efficient way to generate such logs utilizing PHP to determine page load data (time, user IP, requested page, referring page, user client, etc) and SQL to save such data for easy retrieval later. https://swharden.com/blog/2009-07-26-pysquelch-a-python-based-frequency-audio-activity-monitor/ Sun, 26 Jul 2009 00:22:12 +0000 https://swharden.com/blog/2009-07-26-pysquelch-a-python-based-frequency-audio-activity-monitor/ I’m pretty much done with this project so it’s time to formally document it. This project is a collaboration between Fred, KJ4LFJ who supplied the hardware and myself, Scott, KJ4LDF who supplied the software. Briefly, a scanner is set to a single frequency (147.120 MHz, the output of an active repeater in Orlando, FL) and the audio output is fed into the microphone hole of a PC sound card. The scripts below (run in the order they appear) detect audio activity, log the data, and display such data graphically. https://swharden.com/blog/2009-07-23-transition/ Thu, 23 Jul 2009 21:00:00 +0000 https://swharden.com/blog/2009-07-23-transition/ This is an AI Generated Summary Many of the blog posts I wrote when I was young are no longer available on this website.

Although I’m planning on improving the software (better menus, the addition of sound, and implementation of a more efficient algorithm) and hardware (a better enclosure would be nice, battery/DC wall power, and a few LEDs on the bottom row are incorrectly wired), this device is currently functional therefore I met my goal! This device generates large prime numbers (v) while keeping track of how many prime numbers have been identified (N). https://swharden.com/blog/2009-07-01-summers-end-is-nearing/ Wed, 01 Jul 2009 09:40:43 +0000 https://swharden.com/blog/2009-07-01-summers-end-is-nearing/ My favorite summer yet is reaching its end. With about a month and a half before I begin dental school, I pause to reflect on what I’ve done, and what I still plan to do. Unlike previous summers where my time was devoted to academic requirements, this summer involved a 9-5 job with time to do whatever I wanted after. I made great progress in the realm of microcontroller programming, and am nearing the completion of my prime number calculator. https://swharden.com/blog/2009-06-30-prime-schematics/ Tue, 30 Jun 2009 12:25:14 +0000 https://swharden.com/blog/2009-06-30-prime-schematics/ Here’s a schematic of the prime number calculator I’m working on. Last night I finished wiring all 12 shift registers for the primary display, so now it’s time to start working on software. Notice that we have a lot of pins free still. This will be advantageous if I decide to go crazy adding extraneous functionality, such as fancy displays (LCD?, 7-segment LEDs?, VFD?, all 3?!) or creative input systems (how about a numerical keypad? https://swharden.com/blog/2009-06-29-field-day-2009/ Mon, 29 Jun 2009 14:05:32 +0000 https://swharden.com/blog/2009-06-29-field-day-2009/ Last weekend was field day, a disaster simulation / competition for amateur radio operators. In a sentence, people are encouraged to make as many contacts as they can around the world (earning points) using emergency radio preparations (battery and solar powered radios, temporary antennas, etc) for a full 24 hours (2pm to 2pm). I spent the time with the UCF Amateur Radio Club who set up big antennas in a grassy field on campus. https://swharden.com/blog/2009-06-24-reading-writing-and-flipping-bits-in-c/ Wed, 24 Jun 2009 15:28:07 +0000 https://swharden.com/blog/2009-06-24-reading-writing-and-flipping-bits-in-c/ Bitwise programming techniques (manipulating the 1s and 0s of binary numbers) are simple, but hard to remember if you don’t use them often. Recently I’ve needed to perform a lot of bitwise operations. If I’m storing true/false (1-bit) information in variables, it’s a waste of memory to assign a whole variable to the task (the smallest variable in C is a char, and it contains 8 bits). When cramming multiple values into individual variables, it’s nice to know how to manipulate each bit of a variable. https://swharden.com/blog/2009-06-19-reading-pcm-audio-with-python/ Fri, 19 Jun 2009 09:08:33 +0000 https://swharden.com/blog/2009-06-19-reading-pcm-audio-with-python/ When I figured this out I figured it was simply way too easy and way to helpful to keep to myself. Here I post (for the benefit of friends, family, and random Googlers alike) two examples of super-simplistic ways to read PCM data from Python using Numpy to handle the data and Matplotlib to display it. First, get some junk audio in PCM format (test.pcm). import numpy data = numpy.memmap("test.pcm", dtype='h', mode='r') print "VALUES:",data This code prints the values of the PCM file. https://swharden.com/blog/2009-06-18-pysquelch-frequency-activity-reports-via-python/ Thu, 18 Jun 2009 22:59:01 +0000 https://swharden.com/blog/2009-06-18-pysquelch-frequency-activity-reports-via-python/ Update: this project is now on GitHub https://github.com/FredEckert/pySquelch I’ve been working on the pySquelch project which is basically a method to graph frequency usage with respect to time. The code I’m sharing below listens to the microphone jack on the sound card (hooked up to a radio) and determines when transmissions begin and end. I ran the code below for 24 hours and this is the result: __This graph represents frequency activity with respect to time. https://swharden.com/blog/2009-06-13-ucf-tailgate-june-2009/ Sat, 13 Jun 2009 17:14:08 +0000 https://swharden.com/blog/2009-06-13-ucf-tailgate-june-2009/ This morning I woke up at 4:45am, hopped out of bed, and raced to the university parking lot for field day. It’s pretty much a flea market with an emphasis in ham radio and associated electronics. This is a panorama of the parking lot the tailgate was held in, taken from the roof of a parking garage at about 9am. The UCF ARC (the amateur radio club which sponsored the event) is stationed under the white tent. https://swharden.com/blog/2009-06-12-python-powered-frequency-activity-logger/ Fri, 12 Jun 2009 17:42:32 +0000 https://swharden.com/blog/2009-06-12-python-powered-frequency-activity-logger/ __I’m often drawn toward projects involving data analysis with Python. __When I found out a fellow ham in Orlando was using his computer to stream a popular local repeater frequency over the internet I got excited because of the potential for generating data from the setup. Since this guy already has his radio connected to his PC’s microphone jack, I figured I could write a Python app to check the microphone input to determine if anyone is using the frequency. https://swharden.com/blog/2009-06-08-mcppng-nearing-completion/ Mon, 08 Jun 2009 21:00:00 +0000 https://swharden.com/blog/2009-06-08-mcppng-nearing-completion/ This is an AI Generated Summary Many of the blog posts I wrote when I was young are no longer available on this website.

I want to make a prototype which is far smaller and simpler than the final version but lets me practice driving lots of LEDs (30). I expect the final version to have around 80. Also, the heart of this project is an ATTiny2313 microcontroller, and for the full version I’d like to use an ATMEega8. https://swharden.com/blog/2009-06-02-timing-is-everything/ Tue, 02 Jun 2009 21:00:00 +0000 https://swharden.com/blog/2009-06-02-timing-is-everything/ This is an AI Generated Summary Many of the blog posts I wrote when I was young are no longer available on this website.

Summary: The author of the blog post is guessing that they could perform 1,000 divisions per second on a computer display and would take approximately 3472 days (or about 9 and a half years) to complete 300 billion divisions using this method. https://swharden.com/blog/2009-05-30-1102/ Sat, 30 May 2009 18:22:58 +0000 https://swharden.com/blog/2009-05-30-1102/ In my quest to build a hardware-based prime number generator I built a rapid prototype to assess how quickly primes can be found with an 8-bit microcontroller. There is a lot of room for improvement, but the code works. Instead of messing with tons of little LEDs, this design displays numbers on an LCD. Interestingly the library to run the LCD takes up about 90% of the memory of the chip leaving only a handful of bytes to write the prime calculation code in! https://swharden.com/blog/2009-05-27-exhaustion-steering-and-primes/ Wed, 27 May 2009 10:28:19 +0000 https://swharden.com/blog/2009-05-27-exhaustion-steering-and-primes/ I’m completely drained of energy. I visited my wife’s family in Tennessee last week. I left Thursday and came back Tuesday (yesterday). I drove a total of 2,180 miles. The drive to Humboldt, TN (the destination) and back is only 1,658 miles. That means that I drove over 520 miles over the 3 days while at my destination. That’s about 174 miles a day. At 50 MPH average speed that’s about 4 hours in the car. https://swharden.com/blog/2009-05-20-graphing-computer-usage/ Wed, 20 May 2009 08:44:57 +0000 https://swharden.com/blog/2009-05-20-graphing-computer-usage/ I enjoy writing Python scripts to analyze and display linear data. One of my favorite blog entries is Linear Data Smoothing with Python, developed for my homemade electrocardiogram project. I installed a program called TimeTrack.exe on my work computer. It basically logs whenever you open or close a program. The data output looks like this: "Firefox","Prototype of a Digital Biopsy Device - Mozilla Firefox","05/19/2009 9:45a","05/19/2009 9:45a","766ms","0.0" "Firefox","Dual-Channel Mobile Surface Electromyograph - Mozilla Firefox","05/19/2009 9:46a","05/19/2009 9:46a","797ms","0. https://swharden.com/blog/2009-05-19-audio-and-video-on-an-atmega88-microcontroller/ Tue, 19 May 2009 20:49:40 +0000 https://swharden.com/blog/2009-05-19-audio-and-video-on-an-atmega88-microcontroller/ At least 99% of my blog entries contain original content I created. However, I was so impressed by something I stumbled upon tonight that I absolutely cannot resist sharing it. It’s a project which aims to output audio and video simultaneously from a single microcontroller. The author’s site has all the details, but if you watch the video below you’ll be amazed. (Just get through the 30 second narration at the beginning) Apparently the guy rendered video in horizontal lines from the software and outputted audio signals between horizontal lines! https://swharden.com/blog/2009-05-17-attiny2313-controlling-a-hd44780-lcd-via-avr-gcc/ Sun, 17 May 2009 20:27:44 +0000 https://swharden.com/blog/2009-05-17-attiny2313-controlling-a-hd44780-lcd-via-avr-gcc/ After a day of tinkering I finally figured out how to control a HD44780 display from an ATTiny2313 microcontroller. There are a lot of websites out there claiming to show you how to do this on similar AVRs. I tried about 10 of them and, intriguingly, only one of them worked! I think the problem is that many of those websites show code for an ATMega8 and I’m using an ATTiny2313. https://swharden.com/blog/2009-05-15-removing-textile-from-wordpress/ Fri, 15 May 2009 17:56:32 +0000 https://swharden.com/blog/2009-05-15-removing-textile-from-wordpress/ I realized that the C code from yesterday wasn’t showing-up properly because of textile, a rapid, inline, tag-based formatting system. While it’s fun and convenient to use, it’s not always practical. The problem I was having was that in C code, variable names (such as delay) were becoming irrevocably italicized, and nothing I did could prevent textile from ignoring code while styling text. The kicker is that I couldn’t disable it easily, because I’ve been writing in this style for over four years! https://swharden.com/blog/2009-05-14-php-generated-accesslog-is-a-success/ Thu, 14 May 2009 13:33:22 +0000 https://swharden.com/blog/2009-05-14-php-generated-accesslog-is-a-success/ A few months ago I wrote about a way I use PHP to generate apache-style access.log files since my web host blocks access to them. Since then I’ve forgotten it was even running! I now have some pretty cool-looking graphs generated by Python and Matplotlib. For details (and the messy script) check the original posting. This image represents the number of requests (php pages) made per hour since I implemented the script. https://swharden.com/blog/2009-05-14-simple-case-avrpc-serial-communication-via-max232/ Thu, 14 May 2009 11:00:19 +0000 https://swharden.com/blog/2009-05-14-simple-case-avrpc-serial-communication-via-max232/ I recently had the desire to be able to see data from an ATMEL AVR microcontroller (the ATTiny2313) for development and debugging purposes. I wanted an easy way to have my microcontroller talk to my PC (and vise versa) with a minimum number of parts. The easiest way to do this was to utilize the UART capabilities of the ATTiny2313 to talk to my PC through the serial port. One problem is that the ATTiny2313(as with most microcontrollers) puts out 5V for “high” (on) and 0V for “low” (off). https://swharden.com/blog/2009-05-12-random-junk-inda-mail/ Tue, 12 May 2009 11:49:58 +0000 https://swharden.com/blog/2009-05-12-random-junk-inda-mail/ I placed another online order to DigiKey yesterday. They have virtually every electronic component available for next-day delivery. How awesome is that? The frustrating thing is that I’m always trying to get my order in before 6pm CMT so that my package will ship same day, so I rush, and I always forget something! It never fails. 30 minutes after I place an order, I always remember something else I wish I’d added to the order (to save on shipping). https://swharden.com/blog/2009-05-07-proofing-scientific-literature/ Thu, 07 May 2009 15:10:22 +0000 https://swharden.com/blog/2009-05-07-proofing-scientific-literature/ Man, what a long day! Work is so tedious sometimes. This week I’ve been proofing scientific literature using Office 2003 with “track changes”. I make changes, my boss makes changes, I make more changes, and it goes back and forth a few times. I wonder why office 2007 is so bad. Does anybody truly like it, and find it to be a significant improvement upon 2003? … or Vista over XP? https://swharden.com/blog/2009-05-04-barebones-transmitter-test/ Mon, 04 May 2009 22:09:13 +0000 https://swharden.com/blog/2009-05-04-barebones-transmitter-test/ I put the transmitter from the previous post to the test. I changed the circuitry a bit though. I kept the oscillator (50 MHz) is now continuously powered. I programmed the ATTiny 2313 microcontroller (using PWM output) to send an oscillating signal to the base of a transistor (NPN). In this way the microcontroller PWM output didn’t supply power to the oscillator, but rather grounded it. I got a big boost in range this way. https://swharden.com/blog/2009-04-30-a-foot-in-the-qrss-door/ Thu, 30 Apr 2009 09:26:40 +0000 https://swharden.com/blog/2009-04-30-a-foot-in-the-qrss-door/ I’ve been very busy over the past couple weeks. Last Thursday my boss approached me and asked if I could work over the weekend. He wanted to complete and submit a grant by the deadline (Monday at 5 pm). To make a long story short I worked really hard (really long days) on Friday, Saturday, Sunday, and Monday to accomplish this. Monday afternoon when it was done (at about 4 pm), after which I went home and collapsed from exhaustion. https://swharden.com/blog/2009-04-20-diy-morse-code-keyer/ Mon, 20 Apr 2009 14:20:00 +0000 https://swharden.com/blog/2009-04-20-diy-morse-code-keyer/ Over the last couple weeks whenever I had the time I’d work on creating a little Morse code keyer. After a few different designs I came up with the winner. Basically it just uses a bar of aluminum which rocks on a metal pin. Thumb-screws on each side of the balance point (fulcrum?) can be adjusted to modulate the distance the paddle has to go down to be activated, and how high the paddle goes up when released. https://swharden.com/blog/2009-04-15-scott-is-now-licensed-kj4ldf/ Wed, 15 Apr 2009 21:00:00 +0000 https://swharden.com/blog/2009-04-15-scott-is-now-licensed-kj4ldf/ This is an AI Generated Summary Many of the blog posts I wrote when I was young are no longer available on this website.

My wife and I both took our technician exam last week, and this morning I discovered that our call signs have been processed. I’m KJ4LDF, she’s KJ4LDG.

The idea is still in the earliest stages of development, and I further research the idea (for example, I don’t even know if it’s legal) but it’s a cool idea and I want to try it. I know I’ll learn a lot from the project, and that’s what’s important, right? So, here’s the idea: I want to build an incredibly simple, low power radio transmitter that broadcasts data on a fixed frequency. https://swharden.com/blog/2009-04-09-hdd-leds/ Thu, 09 Apr 2009 00:00:00 +0000 https://swharden.com/blog/2009-04-09-hdd-leds/ I was poking around the internet looking at various ways people made smooth-fading LED circuits and I came across the site of a guy who did something pretty creative that made me smile. Before I got too far, I wanted to mention that I saw a ton of plans involving fading LED intensity utilizing 555 timer ICs, but for my purposes a series capacitor before the LED should do fine. Here’s the site which documents the project. https://swharden.com/blog/2009-04-06-i-spotted-an-airplane/ Mon, 06 Apr 2009 21:00:00 +0000 https://swharden.com/blog/2009-04-06-i-spotted-an-airplane/ This is an AI Generated Summary Many of the blog posts I wrote when I was young are no longer available on this website.

Yesterday I went to SkyCraft, early this morning I posted a schematic diagram of a basic circuit concept for a radio/microphone interface box with tone generating functions, and this afternoon I finished its assembly. It’s hacked together, I know, but it’s just a prototype.

This is the most basic circuit I’m currently using, designed using two quad op-amps. I’ve produced some surprisingly good ECG traces and even identified an arrhythmic heartbeat. Currently the device is limited because you have to be attached to your computer, I’m working toward making it a mobile device (powered by a 9V battery) which records voltage data to a minidisc recorder . https://swharden.com/blog/2009-01-30-the-internet-was-moved/ Fri, 30 Jan 2009 21:55:01 +0000 https://swharden.com/blog/2009-01-30-the-internet-was-moved/ I’m working late in lab (as usual) and I went to open Firefox (my default web browser), so I clicked Start and selected “Mozilla Firefox” at the top (where your default browser usually goes in XP).

It’s unlikely. Upon analyzing ~20 minutes of heartbeat data (some of which is depicted in the previous entry) I found a peculiarity. Technically this could be some kind of noise (a ‘pop’ in the microphone signal due to the shuffling of wires or a momentary disconnect from the electrodes or perhaps even a static shock to my body from something), but because this peculiarity happened only once in 20 minutes I’m not ruling out the possibility that this is the first irregular heartbeat I captured with my DIY ECG. https://swharden.com/blog/2009-01-20-diy-ecg-improvements/ Tue, 20 Jan 2009 00:53:00 +0000 https://swharden.com/blog/2009-01-20-diy-ecg-improvements/ ⚠️ Check out my newer ECG designs: Sound Card ECG with AD8232 Single op-amp ECG Instead of using a single op-amp circuit like the previous entries which gave me decent but staticky traces, I decided to build a more advanced ECG circuit documented by Jason Nguyen which used 6 op amps! (I’d only been using one).

It doesn’t flaunt the capabilities of PyGame for game design, but it was a cool concept because it’s very 3D-ish and is done by mathematically processing anti-aliasing splines at impressively high speed. https://swharden.com/blog/2009-01-16-diy-ecg-progress/ Fri, 16 Jan 2009 12:41:40 +0000 https://swharden.com/blog/2009-01-16-diy-ecg-progress/ ⚠️ Check out my newer ECG designs: Sound Card ECG with AD8232 Single op-amp ECG Last night I finished building my DIY ECG as a prototype (I finally got the circuit off the breadboard and onto a plastic sheet).

I’m a software guy (or at least I know more about software than circuits) so I’d rather record noisy signals and write software to eliminate the noise, rather than assembling circuits to eliminate the noise in hardware.

I ran into a snag for a while though, because whenever I loaded data from a text file it wouldn’t properly decompress. https://swharden.com/blog/2008-11-22-run-ubuntu-live-cd-from-a-usb-drive/ Sat, 22 Nov 2008 15:36:16 +0000 https://swharden.com/blog/2008-11-22-run-ubuntu-live-cd-from-a-usb-drive/ I accidentally nuked my laptop’s 80G hard drive this morning (D’OH!) while shuffling around partitions.

I looked around, but I guess blank CD-Rs aren’t something that’s standard in molecular biology laboratories. https://swharden.com/blog/2008-11-17-linear-data-smoothing-in-python/ Mon, 17 Nov 2008 18:50:10 +0000 https://swharden.com/blog/2008-11-17-linear-data-smoothing-in-python/ ⚠️ SEE UPDATED POST: Signal Filtering in Python def smoothListGaussian(list, degree=5): window = degree*2-1 weight = numpy.array([1.0]*window) weightGauss = [] for i in range(window): i = i-degree+1 frac = i/float(window) gauss = 1/(numpy.exp((4*(frac))**2)) weightGauss.append(gauss) weight = numpy.array(weightGauss)*weight smoothed = [0.0]*(len(list)-window) for i in range(len(smoothed)): smoothed[i] = sum(numpy.array(list[i:i+window])*weight)/sum(weight) return smoothed Provide a list and it will return a smoother version of the data.

My system’s back up. I reformatted my main workstation (the one with five monitors) and started loading gentoo on it a few days ago.

I stumbled upon a forgotten URL on the Wayback Machine that shows some of my earliest surviving marks on the internet. It was scraped on in Aug, 2002 when I was 17. This website made use of “cutting edge technology” of the day (like transparent iframes) which only worked on Internet Explorer (not Netscape or America Online’s built-in browser). I remember making a big point about this because I wanted to brag to my friends about my “mad website skillz” but some of them thought my site was really bad and I later learned it was because it only worked in Internet Explorer. https://swharden.com/blog/2001-10-26-the-edge/ Fri, 26 Oct 2001 12:00:00 +0000 https://swharden.com/blog/2001-10-26-the-edge/ Hi 👋 2003 Scott here! I stumbled upon a forgotten URL on the Wayback Machine that shows some of my earliest surviving marks on the internet. It was scraped on in Oct, 2001 when I just turned 16. The page has a JavaScript fly-out menu but none of the links point to pages that were archived. I don’t recall if “the edge” meant anything, other than a “branding” phase I went through briefly as an internet-surfing kid. https://swharden.com/blog/2001-06-17-geocities-hardentechnologies-2/ Sun, 17 Jun 2001 02:37:11 +0000 https://swharden.com/blog/2001-06-17-geocities-hardentechnologies-2/ Hey looks like I wrote the previous section today… weird… oh well. here I go! Today I started researching and I was all bumbed out because Yahoo! changed their ad policies for the personal home pages. It used to me that they could put a geocities ad at the bottom of the page (like a full size banner) and it would stay there. Your only other option was to accept the annoying “ad square” at the top right of the screen. https://swharden.com/blog/2001-06-16-geocities-hardentechnologies-1/ Sat, 16 Jun 2001 02:37:11 +0000 https://swharden.com/blog/2001-06-16-geocities-hardentechnologies-1/ Well I’ve been playing for a few days on the format of this website. I want it to be really “fresh” and “new”… I want it to be really easy to the eye and simple to navigate, yet really complex coding. I want the new internet user to say “this is nice” because it’s so simple and the web designer to say “this is nice” because it’s so complex. It’s a challenge for myself I guess… Through a frustrating series of events I lost the news I was keeping :o( so I just have to start with this one I guess… so far I only have this page done. https://swharden.com/blog/2000-02-29-goldeneye/ Tue, 29 Feb 2000 12:00:00 +0000 https://swharden.com/blog/2000-02-29-goldeneye/ Hi 👋 2023 Scott here! I stumbled upon a forgotten URL on the Wayback Machine that may be the oldest preserved trace of my life on the early internet. The page seen here was archived on Feb, 2000 when I was 14 years old. I probably created this website using Microsoft FrontPage (the 1996 version). Earlier versions of this website had a blue water tiling background, but after watching The Matrix (on VHS, lol) I was inspired to redesign it with green text on a black background.
