I made this Claude Code keyboard as a fun, lighthearted project to keep on my desk at work. In addition to this 3D print you will need 3 mechanical keys and your choice of micro controller that supports USB output. I am using a esp32-s3-supermini and have made the keys map to the “yes”, “yes, always”, and “no” keys.

I have soldered the wires directly from the keys to the microcontroller. It’s a simple setup: One side of each key connected to the ground pin, and the other side of each key to their own GPIO pin. Claude should be able to help set up the code for your specific microcontroller once you have it wired up!
