I've done a similar thing with my Guitar Freax Guitar, but modded it so it can work on Guitar Hero... All fine and dandy, but the button's are all different colours, so I went and added a Green, Red, Yellow, Blue and Orange LED in the side of the neck... Only thing is, the LED's tend to get slightly warm, Causing me to believe that there is too much power runnig through them... The Blue is very dim now and the Yellow looks more orangy...
Any one know where to get 3.3v from the pins of a Joypad? I don't have a multi-meter so's I can't check
