Externally powering LEDs so Arduino doesn't fry

I also wanted to point out that, if you had been more helpful in my threads, i may not have found the charliecube. I found it while I was looking around for different LED cube designs, because the one I was working on was being so difficult. Its still not done, I have some parts to test out, to see if they will do what I need, but meanwhile, the charliecubes have been built, documented, measure (to the best of my abillity), and I've even modified one to be a "safe" version.

In a strange sort of way, your lack of help, has contributed to the development of this resistorless RGB LED cube. Thanks buddy!
