Using Pots to make LED's produce all colors

[StevenF]

I was just thinking that someone could use one of those fanbuses, like the one at PCMods, to control LED brightness. If one had four strands of LED's in series: red, green, blue, and white; theoretically one could adjust the pots to produce the entire color spectrums as well as extra brightness with the white. What do you guys think?

An interesting idea. I'm not sure how well LED's dim. I wouldn't use a fan bus as they deliver too much power and can blow LED's. Go with a simple pot you can get at Radioshack. And to get color mixing you would have to have each LED on it's own pot. Also you'd only have to use the three primary colors red, blue, and green (yellow is a primary for paint not light). As for getting white, well that depends on how well your LED's are matched in light output, corect color saturation, and how close they are togeather. Even if you do get white it won't be as bright as a white LED. But as wow factor it could be a cool case mod. Let us know how it turns out.
