Show HN: I'm cataloging open source electronics

https://www.openappnote.dev/
1•zciwor•1h ago
GitHub's search is a great resource for software development. Being able to search an obscure function implementation and see 100s of examples in code is immensely helpful.

I've been exploring how to make something similar for electronics. To be able to search for a part number and see 100s of subcircuits using that part in context would be just as helpful.

As GitHub has become a home for a lot of open source electronics, the challenge is two fold: (1) search git repos by part and (2) build a universal ECAD visualizer (most people just upload the design files).

Happy to hear how others might approach the visualizer problem. Representing schematics and layouts across ECAD formats is... messy.
