Supercoder 3000

A four-button keyboard for professional programmers

Simon Burkhardt



I stumbled upon this cool little keyboard once. The so called Supercoder 2000 air cooled keyboard for professionals. I thought it would be a fun idea to build one myself.

The Arduino Leonardo, respectively the Arduino Pro Micro is the perfect choice for this tiny project. It's ATmega32U4 microcontroller supports USB HID mode. This makes the keyboard application the easiest thing.

As far as I can tell, my keyboard is much smaller, has no "air cooling" integrated and four instead of just 3 keys. I mean even the best programmers do typos every now and then...

Dear lovers of mechanical keyboards, pay close attention. The Supercoder 3000 uses mechanical Cherry MX blue switches. You can order them on ebay for a relatively cheap price.
