Voltpeek – Vim-inspired oscilloscope software

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…

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.

Voltpeek is a command based PC oscilloscope software. Voltpeek works with the NS1 headless oscilloscope hardware and firmware . To give Voltpeek a try with just the Pi Pico, the NS0 firmware is also available. By command based, we mean that everything in voltpeek is controlled and adjusted via command instead of click and drag or text entry like many other oscilloscope softwares that run on PC. For example, the scale command will put the oscilloscope/software in adjustment mode. The horizontal and vertical scales can then be adjusted using the h , j , k , and l keys. ctrl-c or esc will put the software back into command mode. As may be obvious, this is inspired by the Vim text editor.…from github.com

  • Multi-monitor KVM using just a USB switch2024 · github.com · ▲397

    Simple KVM lets you control multiple PCs from one mouse, keyboard and monitor(s). It is similar to Haimgel's display-switch (https://news.ycombinator.com/item?id=29608967), but it provides a GUI which hopefully makes it a bit easier to set up. It also supports hotkeys which effectively lets you alt+tab between computers. I was surprised by the star-to-download ratio (55:400) on GitHub, so I thought I'd post it here as it might be useful to someone. Feedback welcome! Thanks, Fidel

    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 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://visualrambling.space/moving-objects-in-3d/ feel free to visit and let me know what you think!
