So, I made a keyboard

The document provides step-by-step instructions for building a keyboard from scratch. It lists the necessary tools like a soldering iron, parts like keyswitches and diodes, and gives guidance on laying out the keyboard, soldering the components together, and configuring firmware. The document also describes the author's experience building several prototype keyboards and shares photos of the progression from early models to more polished designs.
