Building a giant USB three key mechanical keyboard

Glen Akins shares his latest build the giant three key USB keyboard:

After seeing this giant mechanical keyboard at Adafruit, I decided I had to build my own. Adafruit made theirs out of wood and used one of their Python-compatible microcontroller boards. I wanted a sloped top on my keyboard. I also wanted to check out what was new with Microchip’s USB device stack. I decided to build my keyboard out of aluminum and use a PIC18 microcontroller.
