Hey there! I made a little app that lets you to calibrate your turntable by putting on any record and tapping a button. It's called Grooved and it uses your phone's microphone to see how fast your platter is going, almost like magic. You can see what it looks like in action here: https://twitter.com/OKatBest/status/1795453042994680148 The app itself is free without ads, subscriptions, or trackers. It's a tool I built for myself, and I just thought someone else might want to use it too. I have never seen this technology being used before, all other apps require you to…

Racketmeter lets badminton players measure string tension using the sound frequency produced when tapping the racket strings. It's 100% free, works in your browser on mobile and desktop, and requires no sign-up or installation. I built it to solve a personal problem. I started playing badminton regularly in 2016 and quickly learned that players often ask stringers to string rackets at specific tensions (like 22 or 26 lbs). But after a few stringing jobs, I began to feel like the tension was inconsistent. Other players told me they just tap the strings and go by ear where "sharper sound meant…

I’m building a robot that can track nerf darts and shoot them out of the air. I’ve worked on other projects in robotics and object tracking (perception for self driving cars), but this has a whole different set of challenges. Nerf rival rounds travel at over 100 feet per second and shooting them out of the air requires aiming systems that are precise to less than half the width of a human hair and timing precision of 600 times faster than the blink of an eye. This is the first part of the series of me building the project (and my first video!) so I’d love to hear what you think!

Hey everyone, OP here. Wanted to share a bit more about Hooper — I started building it with a good friend of mine six months ago. We play a lot of pickup together and were arguing about who has a better jump shot and ended up hacking together an app to settle it The way Hooper works is you can record yourself using the app and ideally a tripod (optional). The app will track everyone, whether its a solo practice, a 3v3, or a 5v5. We think there’s a lot of stuff out there for basketball drills but what we really wanted Hooper to be for is actual game play. That means, it can do things like…

I played a lot of Valorant and got mad, so I made an aim trainer that analyzes your raw crosshair movement to explore your raw motor and perceptual weaknesses instead of scoring scenarios. It also chooses sens and difficulty as part of the tasks, and makes playlists that are optimal difficulty for you to learn and progress faster!

Heya. I created a flexible collision engine for broad detection in C that's also pretty fast. Personally that's my best, so I wanted to show it here. Although... still not as fast as DragonEnergy's one that supposedly handled millions of agents bouncing off each other every frame on an old i3, haha. I hope I get better at this! He set the bar pretty high for me. I was considering including some small function that tries finding the nearest entity, although I think it might be better to simply use query for that matter. Perhaps in the future I will get a good idea of how to do that more…

I built this game to test out the MediaPipe hand-tracking API. Play brick breaker using your webcam + hand movement -- levels get progressively harder with faster speed / smaller paddle. All processing is done in real-time within your browser. This project is built using javascript, html canvas, and mediapipe hand tracking. This game is free and open source, offered under an MIT license. Github repo: https://github.com/collidingScopes/manual-brick-breaker Hope it's fun for you -- would love to hear feedback and suggestions for improvement.
