Device-Test

What it does

Device-Test is a free browser-based toolkit for checking microphones, cameras, screen sharing, displays, keyboards, speakers, network status, and device sensors. Every test runs locally on your device, so camera, audio, location, sensor, and diagnostic data is never uploaded to our servers. It works without an account and gives focused, real-time feedback before meetings, recordings, classes, or device handoffs.

Free online tool to test your microphone, camera, and screen. Check if your devices are working properly before meetings.

Quickly test your microphone, camera, and screen sharing capabilities. Make sure everything works before your next meeting. Test your microphone input with real-time audio visualization and volume levels. Preview your webcam video feed and check camera quality before meetings. Test screen sharing capabilities to ensure smooth presentations. Check your screen for dead pixels, bright spots, and backlight bleeding with solid colors. Test every key on your keyboard with visual feedback and progress tracking. Test click, scroll, and reaction speed across five focused modes. Test your MIDI controllers with a virtual piano and real-time event logging. Test your speakers with tone generator, stereo…from device-test.com

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  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…
