我把摄像头变成了乐器：从手势识别到 Web Audio，分享 5 个真正踩过的坑 最近做了一个有点不一样的浏览器小项目：用摄像头识别双手动作，再把手的位置和姿势映射成和弦、音高、音量和音色。 不需要安装软件，也不需要麦克风。打开网页、允许摄像头后，就可以隔空演奏。 项目地址：[GestureSynth.me]( https://gesturesynth.me/) 建议使用最新版 Chrome 或 Edge 。摄像头画面只在本地处理，不会上传。 ## 真正难的不是“识别到手” 最开始我以为，只要 MediaPipe 能返回手部关键点，剩下的事情就是把坐标转换成音符。 实际做下来发现：**识别出一只手很容易，让它变成一个“能演奏”的控制器才难。** 摄像头每一帧都会返回一组手部关键点，但这些坐标会轻微抖动，偶尔还会丢失。如果直接把原始坐标连接到音高或者音量，听起来会非常不稳定。 最后形成的处理链路大致是： ```text 摄像头 → 手部关键点识别 → 提取手掌位置、距离和手势 → 平滑、死区和状态保持 → 映

💖 I built my first app — K-pop Creator Hub! It’s made for K-pop fans and I’m constantly improving it. I’d love to hear your feedback and ideas. Every suggestion helps make it better! 🔗

It's 3 AM. You're mass-producing spaghetti code with an AI copilot and your lo-fi playlist died two hours ago. "3 AM Code" fixes one of those problems. AI-generated on in about 60 seconds, powered by GPUs from the GamerHash AI network. Vibe coding deserved a vibe anthem.

I built the Mandarin learning tool I wanted for myself, then got carried away polishing it into a real product I've been learning Mandarin for a couple of years, and I wanted my reading practice to actually match the words I was studying. Graded readers are great, but they're not related to the spaced repetition practice I'm doing in Anki. So I built a small tool for myself: it generates short stories and sentences from the vocabulary you're working on (the HSK 1-6 collections

Built and shipped my first web app before my CSE even begins! 🤯 I don't know how to code (yet), so I used @Lovable to turn my idea for Sonora Rhythm into reality using just prompts and logic. Check it out: 🧵👇
