Nobody asked for a crab keyboard…
So obviously I built one.
In this video, I design and build a tiny 4-key media controller shaped like a crab — complete with claws and eyes that control your music. Volume, play/pause, skip, rewind, and fast-forward… all with just four keys using smart combo inputs.
This project covers the full process:
Sketching the concept
Vector design in Inkscape
Designing the PCB in KiCad
Creating the case and keycaps in FreeCAD
Slicing models in Ultimaker Cura
3D printing with easyPETG by 3DJake
Soldering, battery management (LIR3032), and final assembly
This little crab runs on a rechargeable coin cell battery, uses direct wiring, and fits everything into a compact custom PCB. Cute on the outside, clever on the inside.
