This was a fun weekend project. It's not perfect, and I probably ended up spending more on the parts than I would have buying a pre-made one, but I'm really happy with how it turned out. I used an Arduino ESP32 board so it can connect to my pc via Bluetooth, and also included a rechargeable LiPo battery so it's completely wireless once charged. Still need some labels. Thought I'd share in case anyone was thinking about trying this on their own instead of buying!
