Electronic:
Microprocesor: Atmel 16 (aka Arduino, but I prefer DIY versions because the comercial Arduino is 3 times more expensive) Two step motor with self developed electronic circuit.
Software used for programing: Bascom AVR free edition. Can be easily passed to Processing, if required. (it´s nearly the same code)
Raider:
For the exhibition I need a video projector that has a high contrast and displays black as much black as possible (maybe one with the DLP technology). Further on I need a DVD Player. If you don’t have one left, I can also bring my Player.
