I have rebuilt the Markdown to PDF converter on You paste your text or Markdown, you get a properly typeset PDF back, and your AI agent can do the same over MCP or a plain API call. No sign up, no key, free. Had built this a long time back as a fairly basic thing and then left it alone, and over the last few weeks I could see a rise in traffic. Took a fresh look and found that lot of it was not rendering. Headings below a certain level were being dropped, nested lists were coming out flat, and code blocks were losing their formatting. What is there now: - Page breaks where you want them, using :::pagebreak::: on a line by itself - Tables, nested lists, task lists and code blocks all render properly - Greek letters, maths symbols, arrows and the rupee sign come out right - Emoji and symbols do not break the render - Plain dot txt files keep their line breaks Live tool at API & MCP docs (humans): API & MCP docs (AI)

Built a free tool site to help my brother study — now has 100+ tools, would love feedback My brother's in high school and needed something more visual to study chemistry, physics, and math, so I used Claude to build him a simple site with interactive calculators and visualizers. I'm not a programmer or from a tech background, so without AI this wouldn't have happened, at least not this fast. It ended up helping him a lot more than I expected, so I kept expanding it, added a bunch of other

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
