Well, I started up working on my LED fixture. Right now I am using an Arduino UNO as a controller, a real time clock (RTC), and controlling about 80 LEDs. I might end up adding a temperature probe as well to have the Arduino monitor the water temperature as well. However for now I am only going for the lights.

This is where I have the sample circuit wired up on a breadboard. I am using two power supplies, one for the controller and another one for the LEDs. I was going to use a power supply from an old printer but it will only allow me to run about 21 LEDs and I need quite a few more than that.
