RaspberryPi0W with eInk display beer tap handle (IoT tap handle)

This is a beer tap handle that encloses a Raspberry Pi Zero W outfitted with a 104x212 pixel eInk display. There's a cutout in the side to plug a microUSB cable into the Pi to power it, whenever you need to ssh into it to update the display. Pi and display slide in via the top, and the included cap snaps right on. Walls are 4mm thick to (try to) handle the force of the occasional stuck tap. You'll need a 3/8"-16, 1-1/8" long threaded coupler and a 3/8"-16 bolt all available from Home Depot (
