What it does

Free browser-based hardware tests for your mouse, keyboard, and audio. Run a double-click test, keyboard ghosting test, spacebar CPS test, stereo audio test, and scroll test — no download required.

Free, browser-based diagnostic tools to check your mouse, keyboard, and audio. No downloads, no sign-ups — just instant results. Detect a failing mouse switch by catching unwanted double-clicks that happen within milliseconds of each other. Press multiple keys at once and see exactly which ones register to find your keyboard's rollover limit. Mash the spacebar for 10 seconds and measure your clicks-per-second speed and switch responsiveness. Play a clean tone in only the left or right channel to confirm your headphones and speakers are wired correctly. Scroll up and down to check for skipping, stuttering, or a jumpy scroll wheel encoder in real time. Not seeing the diagnostic you need? Let…from setuptester.com

  Clipto MCP▲655

  Hey HN, We recently built Clipto. It’s a tool that lets you search over terabytes of video, audio, and images on your computer, without relying on the cloud. Motivation: we probably all had this similar experience, we know a moment exists in a video or audio, but finding it takes hours scrubbing the timeline. You can send all the media to process in the cloud, but it’s slow, expensive and raises privacy concerns. So we decided to build our own on-device media search engine. How it works (high level): 1. We ingest video, audio, image; normalize formats via ffmpeg; run content analysis to…

  Simple algorithm and color space to generate diverse skin tones▲627

  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…
