For a schoolproject I am making a light armature and one of the requirements was to work with RGB led's. My idea was to make a reflective surface that can move in a wave-ish sort of way (I've already got that working with servo's). And let bright LED's reflect off it onto the walls & ceiling.
I've looked around to find some bright enough LED's and came across 3W RGB LED's, I've been trying to make them work with a PC power supply and mosfets but I can't find a good guide to start with. Currently I'm just powering them directly through the PWM and changing the colour with 3 potentiometers, but they're just not as bright as I want it to be. I'm also just trying out 1 power led just to test out, I figure they will be even dimmer when I connect a couple of them?
