ok what i want to try to do is, create a circuit that uses the parallel port to control my CCFL and fan voltages. I dont care about the software I can get that to work. But I need a circuit that will take the information from the parallel port, have a molex connection for power, and outputs of 1 or 2 molex connectors for CCFL's, and 1 or 2 molex connectors for controlling the fan voltages plugged into it.
I would like to be able to have software say, apply 7v to fan A, turn on the CCFL's, and apply 12v to fan B, and to be able to turn them all off, or all on (full power).
I know this is possible, but I am terriable at electronics.

Thanks for your time.
