I started by building a programmable mechanical keyboard based on this macropad tutorial (see link). If you want to simplify it somewhat, replace all the microcontroller circuitry (oscillator, capacitors, USB interface, etc.) with an Arduino, and use through-hole diodes. It's a really cool feeling to finish your design, order custom PCBs from jlcpcb, do a bit of soldering, and end up with a useful, working keyboard. https://wiki.ai03.com/books/pcb-design/page/pcb-guide-part-1... |
