Handwired keyboard
A keyboard assembled with a handwired switch matrix in a 3D-printed case.

Wiring a keyboard matrix
I wired the rows and columns with 22-gauge solid-core wire and 1N4148 diodes inside a 3D-printed case. The work took roughly 14 hours.
This project was soldering practice and an exercise in keeping a repeated wiring pattern organized across the whole keyboard.
