I’ve been using Windows as my daily use lately despite I have been using Mac/Linux for a long time, but I keep running into all sorts of issues, so I’ve been fixing them vibe-coding with Claude. I’m gonna dump all that stuff on This blog is fully automated with Claude Code, from coding all the way to reporting. It’s nothing special—anyone could do it—but it’s actually pretty fun once you try it. The only annoyed is that it burns through tokens like crazy. Most of the tips are pretty interesting, so I hope you find them useful.

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
