After 7 months, 3 iterations, and about 12 hours straight of coding I finally got this project together! It's a pico-powered Pomodoro study timer. About a year ago I learned about the Pomodoro method of pacing study/work sessions and fell in love. I had issues with the ones on web pages because I couldn't take them with me on my brakes and the mobile versions cost money, so I decided to spend triple that on making a physical timer dedicated to the Italian tomato timer gods. I do plan to add more functionality down the line so stay tuned.
Nearly all parts can be found on Adafruit and there's a parts list on GitHub with links.
Any chance you have a schematic or wiring diagram?
