Etch A Mouse (Rotary Encoder Mouse)

thingiverse

This is a straightforward project for seasoned solderers that serves as an excellent introduction to QMK for hand wiring custom mechanical keyboards. It can be assembled just like the picture shows, or you can use it as a fun breadboard project. If you'd rather change the firmware and compile it yourself, you'll find the necessary files here: https://github.com/BiscuitsOnTheFloor/qmk_firmware/tree/encoder_mouse/keyboards/handwired/etch_a_mouse
