So is that to say I am suppose to have 3 power supplies? would anything bad happen if i chose to use one one anode and one cathode? if there is only one power supply I don't see how the number of pads helps it draw current.

any of the interface's would work. the actor will be typing on a key board but it can be a prop key board and the controller can be operated off camera (if need be). i would prefer to have a certain set of numbers pop up, then cycle randomly, then end on another certain set of numbers. i have a lot ...
