Show HN: I'm working on cataloging open source hardware designs (opens in new tab)

When starting a new hardware design, I often find myself pulling up familiar boards (like Adafruit or Sparkfun's dev boards) almost as often as the chip's application note. A full reference project provides useful context, like which voltage regulator they used or how a USB port is wired.

But, it's kind of an awkward process because I'll have to download the design files from Github and open it in the native CAD software (Eagle, for example). Plus, there's no easy way to search for a specific electronic component in Github and find relevant designs.

I've been toying with how to solve this. I'm thinking of a "Dribbble for electronics". A searchable, visual way to explore open source hardware designs without jumping between browser and ECAD.

I made a script to crawl Github for open hardware designs, then generate a schematic and interactive BOM for each design. Now, you can (hopefully) search for "ESP32"[1], "WiFi"[2], or "Bluetooth"[3] and browse relevant designs to view in browser.
