I have actually only started testing it with one 4-LED board. If you go to the flickr (http://flic.kr/s/aHsjzsbo73) photos you will see what the setup currently looks like.
Do you think just the four LEDs would need an external power supply? I have no problem with adding one. I've had to do so with my other projects.

I there are 4 capacitors and 4 resistors in the design. The photos from flickr show that much better.
I appreciate the help. As I said, i'm much more of a programmer than I am an electronics tinkerer.
