Over the weekend, I took my previous rats nest design and turned it into a more professional design by etching copper clad, drilling holes and assembling it. I've design it to run 5 sets of 1w leds for my ten gallon as a test tank. I wanted to have 6 cool white, 6 warm white and 3 blue. This controler is using Atmel ATMEGA328-PU microprocessor. I'm planning on loading Arduino bootloader on the chip so I can upload new programs to it easily. What I've done, anyone can easily replicate using Arduino Uno rapid prototyping board from Radio Shack. You would need a uno prototype sheild, 510 mosfet resister and 10k ohm resisters. (Note: Sparkfun.com has good tutorial on using mosfet with arduino) The reason I've chosen to make a custom design is to cut costs because I have so many tanks. If you have a one or two tanks, Arduino Uno would be a better choice. I hope to get a little more development on the controler over the 4th. If anyone is interested, I have a copy of the arduino lightning code used is this video
