I'm trying to come up with a way that I don't need to use a resistor attached to every LED like a lot of people use. The internet has some plans how to wire them with LM317 voltage regulators and one resistor.
If I can get this design to work, I can use my 12 channel light pattern generator to hang 36 or 48 lights off the controller with 12 resistors/lm317's next to the controller. It might give me more room in the brain but I'm just speculating at this point. Besides, I just fried a few LED's and the LM317 so I'll order more from Allied electronics and do more lighting experiments next week.
The radio shack electronics learning center has been helpful.
