Design electronic circuits and PCBs in your browser with KiCad, no installation required.
ViktorEE · HN
KiCad, a PCB EDA suite is now working in a browser, you can try it at the link, there's a demo project or you can bring your own. Firefox is best, Chrome is good, Safari is "working". We’re Emergence Engineering, a dev shop from Hungary, mostly working with rich text editors, CRDTs. PCBJam started as my (Viktor, CTO, ex-electrical engineer) hobby project but as time went on I put more and more energy into it, and a product started shaping up in my head, in the last few months we’ve started to focus on this project a bit more, and this is the first MVP~ish result. This project is a ton of fun, ton of learning, ton of improvements over improvements: - I thought there must be ways to emulate the PCB canvas OpenGL code on the web. And yes, there are a lot of ways, all of them very buggy. Turns out it’s faster to just write WebGL code that works with KiCad’s Graphics Abstraction Layer if you add the right intermediate debugging steps. I (with Claude) implemented the features and compared

building in public: a tool to practice real work instead of courses saw so many people finishing courses and collecting certificates like they're collecting pokemon cards. So we built something that closes the gap between "i finished the course" and "i can actually do the work" it's tasklearn.app , you get real industry tasks, you attempt them, you see how far you actually get. no videos, no tutorials , just the task itself and ai feedback on what you did. learning th
