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

Just launched "Blue TAO CODE" at . My goal is to create a user-friendly front-end to $TAO. You can now Code, chat, create videos, images, music, search, and do fake AI detection. And there's a "FUN" page with projects created using CODE or other subnets. Check out Xagram and ratemaxxer. With Code, you can have the AI create code and you can also deploy code to production. I am paying 1/250th the cost of Claude Code. So have at it!

I built this trendy site inspired by @ybhrdwj , @s4tr2, and others; all credit goes to them. This is pretty much vibe-coded. I have also added my region bus uncle's playlist😎; check it out. Website:

I built a task manager that replaces priority levels with a hard cap on what "now" means Hey r/SideProject -- I built this for myself because every task manager I tried had the same problem: everything felt high priority. The core idea: instead of High/Med/Low (which fails because everything feels high), you get three buckets -- Now, Next, Someday -- and a hard cap on how many items "Now" can hold. When it's full, adding something new means consciously swapping it for something alread
