Design electronic circuits and PCBs in your browser with KiCad, no installation required.
ViktorEE · HN

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

Access free mental health tools and psychological resources in a privacy-focused, login-free platform.

I’m a psychologist, not a developer. Over the past few months, I used Google AI Studio to build Psycurate.com Why? The digital mental health space has become exhausting—too many great tools are buried under aggressive monetization, mandatory tracking, and corporate bloat. This website wants to be an accessible alternative. What Psycurate is about: * Privacy First: A space specifically for tools that respect the person using them.
