I built a hype almanac — a countdown calendar for everything you're waiting for Twenty-ish years ago I built a little tool just for myself to track release dates of video games I was hyped about with a funny js hype graph. I love to be able to look fw to things in my calendar. So I rebuilt it properly this time (vibe-coded the whole thing) and figured I'd share it: hypanac.com (hype + almanac -- back to the future) What it does: One calendar for everything you're looking forward to — ga

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

Vibe-coded this, I’ve been listening to blues a lot lately while coding.
