MouseDiag

MouseDiag: Free Mouse Test & Diagnostic Tools

What it does

Free mouse test online. Diagnose clicks, scroll wheel, sensor tracking & polling rate in 60 seconds. Browser-based, no download needed.

Test your mouse online for movement, left click, right click, middle click, double-click behavior, scroll-wheel input, and browser-observed mouse event rate. No download required. Use the interactive testing area below to check common mouse inputs in real time. Follow the instructions above. Move, click, double-click, and scroll inside this area to test your mouse. A mouse diagnostic test checks whether your mouse is sending common input events to your computer and browser. MouseDiag lets you test pointer movement, left-click input, right-click input, middle-click input, double-click behavior, and scroll-wheel activity from one interactive testing area. This can help you narrow down…from mousediag.online

  • 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:…

    Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…

  • I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes&#x2F;sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.
