I hope this is right?

I’ve never actually done circuitry that involved looking at and copying datasheet schematics before, so I hope that’s right.

This is a watch! It uses a charlieplexed grid of LEDs, which means only one LED is on at a time, but human persistence of vision makes it look like many are on. There’s also a clock and an accelerometer, and the whole thing is run by an ATtiny. So I’ll have to go refresh c++ later.
