Nice work! I got into electronics with infrared remote decoding and ESP chips, so this was a bit nostalgic and fun to read :) Making a PCB is the next step, and it's quite easy to get started with KiCAD, especially if you're just mounting header sockets to pop in the various boards you're using. Good luck!
