I bought some RGB 5mm 8kmcd LEDs off ebay, arrived in the mail friday. They have a viewing angle of 25 degrees. Got it hooked up and realized how cheap they were. Each color points off in a different direction. With the LED sitting on the table, the color spots on the ceiling are about 2-3' feet from center to center between blue and green, red in the middle. With a color fading script on the arduino-based controller "Ardweeny", the colors don't blend at all, except for where the color spots intersect. But its not a clean mix like I've seen in videos on youtube, and the separation of color is really obvious in fog.
Somehow, I need a cheap solution to getting the LED to point in a single direction, and have the colors mix evenly. Right now my best idea is to use a reflector, like out of the older style flashlights, something fairly narrow. Of course I cant find any, so my only thought is to melt and form plastic from plastic bottles into the appropriate shape, maybe get a mold of some sort to help. But I'm thinking attempting to melt the bottles aint the best idea, even if I do it outside. And of course I dont mean melt into a completely liquid shape, but soft enough to mold.
I'd need about 50 reflectors or whatever, and I don't want to spend a whole lot of money on this. I'm trying to get a nice clean spot beam effect, that shows up nicely in a fog. Does anybody have any ideas that could help?
