I took up this personal project in my garage from ideation to production after coming across it on Amazon. The idea was the make a mini keyboard with 5 of my most used keys: Space, Enter, Escape, Shift, and Delete.
IDEATION:
I wanted to have one long row with 5 keys so the case design would be a stacked acrylic concept that would house the PCB and Arduino that would connect to the standard MX Cherry-style keyboard switches.
Initial Sketches of the 5-Piece Keyboard Design
3D Printed and Laser Cut Parts for the keyboard.
Arduino and Coding the circuit.
Final Result of the 5PK.
