For a while, I've thought it would be cool to have a lightsaber with a blade that changes colors. And not like I hit a switch and it switches from one color to another, I mean constantly cycling through colors. So for a while, I wasn't sure how I'd be able to do something like that. Well about 2 weeks ago while I was moving things in rooms that were about to be repainted in the house, I looked at a color changing light I bought from Walmart several months ago and had a "palm-to-face" moment.
It the same as this one but displays a different effect on the wall.

Here are some pics I took after I opened the light up. The board inside controls the LEDs perfectly for what I want. Power is gradually put into and out of each LED in a constant rate to product a nice cycle of red->orange/yellow->green->light blue->blue->purple. But since I'm still learning this electronics stuff, I thought some of our resident electric gurus could give me some advice and help in this project.
I figure I may be able to use one of the RGB Rebel stars in place of the LEDs there. And I'm not sure about the voltage and all that the board could handle. From my experience, most LEDs run on a forward voltage around 2vdc or 3vdc. But this plugs into a wall socket, which should be 120vac. So the board must be changing the ac to dc(like an inverter for EL, but opposite way around) and bringing down the voltage, right? And I'm not completely certain about what function some of the parts on the board serve. I think the black cylinder part is a capacitor, and I know a resistor when I see one, but what about the blue thing and the rusty brown thing?
Any help you guys can give me would be greatly appreciated.
