Cool as !

Im in the process of doing one myself, heres my first prototype made from a commercially available knock down/reset (wanted to see how they worked), an old epson printer, 2 servos, bits and bobs. Its controoled by an arduino which is basically a micro controller board which is programmed from a pc and then can run as a standalone or pc controlled. The one in the vid is manually controlled via switches etc at the end of a long cable.
I have a wireless module and the idea is that the target part can either run on its own, maybe a set of "program modes" or can be remotely controlled from a pc/lappy/pda which could then log peoples scores, have more variable "games" etc.
Hope you like it, sorry about the crap quality vid but had phone in one hand and controls in the other !
