The firmware is written by K3NG http://radioartisan.wordpress.com/arduino-cw-keyer/ . The firmware has all the features of Winkeyer by K1EL and some more. Can be used with most contest loggers.
Oscar does not supply the Arduino, I had to buy an Arduino Uno on eBay. The arduino is the "engine" of the project. The assembly time was hardly two hours an a little bit. It took a whole day to source the enclosure and drill all the holes.
