Building a keyboard from scratch
The document outlines the process for building a keyboard from scratch. It discusses selecting and obtaining the necessary tools and parts, including a microcontroller, switches, wires, and case materials. The document guides the reader through designing the keyboard layout, circuitry, and firmware. It also shares the speaker's experience building multiple prototype keyboards through an iterative design process. The goal is to demonstrate that building a custom keyboard is an achievable project that allows for creative hardware design and customization.
