Yeah I was going to say you may not want to use the USB port out of a computer. I think they typically only take 5 volts. I'm pretty sure the circuit board in the picture that fk1022 posted is what allows that to use 12 volts. You may fry something.

 

hey fk1022 that looks awesome man. By chance do you know if its possible to do something similar with an auxillary input so i can use my ipod??

 

i really have no idea ramslt
