Voltpeek – Vim-inspired oscilloscope software

In plain words

Voltpeek is PC-based oscilloscope software controlled through Vim-style commands, designed for headless operation with custom oscilloscope hardware. Built for electronics enthusiasts who want a simpler alternative to traditional oscilloscope software, it offers convenient waveform capture and image saving without complex menus. The accompanying hardware provides 7.5MHz bandwidth and 62.5MS/s sampling, suitable for basic debugging and measurement tasks. The software prioritizes streamlined command-line control over cumbersome graphical interfaces.

In the maker’s words, at launch

This is software for my headless, PC based oscilloscope, which is controlled entirely via commands similar to the Vim text editor. I built this because I liked the idea of headless oscilloscopes; I always have my laptop around when I’m working on electronics anyway, and it’s very convenient to save images of captured waveforms. However, I found the software for off the shelf models to be annoying and cumbersome to work with. In my experience, this holds true both when opening the software and connecting to an attached oscilloscope, and when adjusting the scope settings using menus and buttons. I have also built my own oscilloscope hardware for use with Voltpeek. The specs are nothing to write home about (7.5MHz BW, 62.5MS/s), but they should be adequate for some basic debugging and measurement tasks.

  Eigendrum - Draw any shape and hear what it sounds like as a drum▲243

  Hi HN, I built Eigendrum, a web tool that solves the 2D wave equation for arbitrary shapes so you can hear what they sound like as drums. How it works: * Solves -∇²u = λu using finite element analysis (Kφ = λMφ) on a triangle mesh. * Validated to <0.1% error against closed-form solutions for circles (Bessel zeros) and rectangles. * Sound model factors in strike location, Rayleigh damping, and mallet width. * Includes Kac drums I & II to demonstrate identical sound spectra from different geometries. * No frameworks, build steps, or dependencies. Repo and tests:…

  I spent 6 years building a ridiculous wooden pixel display▲1,145

  I built the world's most impractical 1000-pixel display and anyone in the world can draw on it. It draws a single pixel at a time and takes 30-60 minutes to complete a single image. Anyone can participate in the project by voting for the next image to be drawn, and submitting images. https:&#x2F;&#x2F;kilopx.com&#x2F;

  Kitten TTS – 25MB CPU-Only, Open-Source TTS Model▲1,003

  Kitten TTS is an open-source series of tiny and expressive text-to-speech models for on-device applications. We are excited to launch a preview of our smallest model, which is less than 25 MB. This model has 15M parameters. This release supports English text-to-speech applications in eight voices: four male and four female. The model is quantized to int8 + fp16, and it uses onnx for runtime. The model is designed to run literally anywhere eg. raspberry pi, low-end smartphones, wearables, browsers etc. No GPU required! We're releasing this to give early users a sense of the latency and voices…

  I was curious about spherical helix, ended up making this visualization▲865

  I was wondering how I can arrange objects along a spherical helix path, and read some articles on it. I ended up learning about parametric equations again, and make this visualization to document what I learned: https:&#x2F;&#x2F;visualrambling.space&#x2F;moving-objects-in-3d&#x2F; feel free to visit and let me know what you think!

  The current sky at your approximate location, as a CSS gradient▲788

  For HTML Day 2025 [1], I made a web service that displays the current sky at your approximate location as a CSS gradient. Colours are simulated on-demand using atmospheric absorption and scattering coefficients. Updates every minute, without the use of client-side JavaScript.
