Finished wiring!

Oh the horrors of 4-layer pcb. I fixed up an error with the accelerometer footprint and added a copper pour, so that should make the IS31 chip happy.

Looks kinda like the night sky, which I like.

Added these little guys (pioneer 9, pioneer 10, jupiter icy moons explorer) because there’s a webcomic that I like

I have to do my homework now xd

I used the terminal easyeda2kicad to get 3D models and finally configured them right! dot wrl files don’t do well on KiCad. Also checked off the shipping reqs and filled out the BOM, so off we go

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.
