A month ago [Andreas] started playing Starcraft 2 again. As he was not comfortable with the default hotkeys on a normal keyboard, [Andreas] decided to build his own.
He started by salvaging keys from an old keyboard he had lying around, then 3D printed the case you see in the picture above to fit them. The keyboard electrical design is a simple matrix and it appears that he etched the PCB himself. To provide the required USB connectivity, the Atmega8U2 was chosen. It comes with a pre-programmed USB bootloader that [Andreas] chose to activate when the left key is pressed at the system startup. The HID class was implemented using the LUFA-USB Framework and the final product is definitely good looking.
All the files required to duplicate his design can be found here. You can also checkout another starcraft keyboard and an ergonomic keyboard that we previously featured.
