The microcontroller is just a PICAXE-8 i had sitting around, a complex micro isn't needed for this application. with suitable firmware, the lighting could be controlled via RS-232 in real time. What do you think?
Neat, but increase the DPI of your schematic so you arent missing some of the lines. What was the heatsink you used? Just chop up and old one you had around?
Click to get the full sized image. The LED's heatsink is from a low-end GPU of some sort, cut down into a kind of triangular shape.
You seem to have some air trapped in your watercooling. For what reason did you choose to use the 12V supply for your luxeons when they all have a forward voltage less than 4V?
There's no watercooling installed, only the radiator. A short hose connects the two radiator hose barbs to prevent any water trapped in the rad leaking when the case is carried. You could use 5V or any voltage for the Luxeon's, because it's current regulated as you can see. By using 12V, you could put 2 or 3 series LED's on each channel with no hardware modification.
hehe... I'm still used to IE having the little finger over all links... *mutters on about firefox making him look like an idiot* Do you PWM the brighness, or do you just have each LED on or off?
PWM, so it's like a flashy fading sequence. I'll try and get a video up in future. I'm not sure what the voltage overhead in the LM317 circuitry would be, i guess it can't be much more than 1.5V, so yes, 5V would probably give 3.5V at least across the LED's, and would probably remove the need for a heatsink on the regulators. I might try that.
