I'm pretty proud of my weekend project. This is a 7-channel, 300mA solenoid driver based on the Teensy LC designed to fit nicely inside of an enclosure.

I wrote up a tutorial for how to make it render well with EagleCAD - Fusion 360 integration. It's a bit of a hack, but worked great once I got the hang of it! Credit for the Teensy LC model goes to https://grabcad.com/library/teensy-lc-1#! which I imported directly as a f3d file to keep the beautiful board decal.
