'Heat resistant', meaning it it won't fall apart. It's call welding epoxy, I had it laying around. I felt the aluminum and it does feel warm so it's doing its job.
Ok, more pictures...
Here are the different color stages.. The arduino is running a clock and will trigger these events.
I'm treating this tank like a stage and these are stage lights, making this dramatic and such.
it gets triggered at 08:30:00
sorry for the blurriness.
a close up
it's cool to see red shadows.

I don't think it's all that bright but it's a low tech tank. Also the power supply isn't supplying enough amps but it's safer this way.

I didn't wait around all day to take these pictures.
I wrote a program in Processing
, a java lite type application. As you can see from the screen, I use this to sync my computer's time to the arduino. And I made switches (buttons on the screen) to turn on the lighting events so I don't have to wait around. When there's a power outage or if I unplug the arduino, the time is wiped out. All communication is through a usb connection.
Overall, I'm digging this RGB LED. The colors on the fish are enhanced. I have some chili boraras in the tank and they pop out like fire! or red hot chili peppers.
