Why Build This?I use Raycast almost every day and wanted a dedicated one-key keyboard for it. With various micro controllers, key switches, and a 3D printer in hand, creating one seemed straightforward.My goal was to design a keyboard that looks good and is simple.Full article instruction on my website.MaterialsFor this project, you will need:Components:1 Arduino Pro Micro1 Mechanical keyboard key switch (blue or any other type)Wires1 LED1 200 Ohm ResistorUSB A to Micro USB cableTools Required:3D PrinterSoldering iron Design ProcessI used Fusion 360, which is free for personal hobby projects, to design the 3D model. It took several iterations to find the right shape and size for comfort and to fit all components.
