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

Built a free toolkit that grew into 5 sites, 200+ tools, no signup required I started this a few days ago to build a free invoicing tool for freelancers because everything I found was gated behind a signup wall or a "free trial." It turned into a small portfolio of 5 sites, each aimed at a different kind of solo operator: Ledgerline: invoicing, contracts, and tax calculators for freelancers Rentline: rent increase letters, late fee calculators, and lease guides for landlords Sellerline:

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)

做了个托管 PDF 的二维码工具 最近老婆一直在抱怨给老外传 pdf 文件很麻烦，之前一直是走邮件附件。麻烦在于文件一改就得重发一遍，对方手上可能还留着旧版本，来回确认到底看的是哪一版特别费劲。 想着不如给她生成个二维码或者短链接，文件更新了直接换后面的，链接不变。搜了一圈现成的工具，试了几家都有点别扭。有的免费能生成，点下载却要注册。还有的会在扫码后的落地页上放广告，但那是发给客户看的东西，不太合适。 干脆自己做了一个： https://qrcodeforpdf.app 传个 PDF ，出一个二维码和短链接，扫了在浏览器里直接打开，不用下载也不用装 App 。文件可以随时替换，码和链接都不变，已经发出去或者印出去的都还能用。不注册就能生成和下载，PNG 和 SVG 都没有水印，应该是比较完美的，刚好也作为自己的一个小项目，也欢迎大伙们试用给建议，逐步优化！
