So, I went to Ebay and purchased 30 LED's for around 15$ Canadian. Very cheap for Ultra-bright LED's, especially blue ones.
I cut a piece of Schedule 5 poly tubing (mainly used for general water piping) in half. The first use I had for this was to be an air-ator for the tank (notice all the small holes). When that didn't work, I figured I could still use it for something.
Along comes my moonlighting idea. Rather than spend big bucks for something from the LFS, I figured, I can do this myself for way cheaper. And I did!!.
I had a 'walwart' hanging around that would work, one that delivers 12 Volts. I bought the parts to make a fading circuit I found on the net. From work( I work in electronics manufacturer) I got some small pieces of proto-board to mount the parts for the circuit.
Once done, I put the LED's into the cut tube, soldered tham and then wired them up. The following is all the results I have.
The black box in the photo is the control box to control the fading speed of the LED's, from slow to very fast, or constantly on.
All I do is put the tube in the area where my flourescents are. The effect is great! There was no way I could get the system on film working with the tank, that's why its on the couch! My digi-cam would not pick the light up, but believe me, it is fairly bright, and very neat to have!
