I got this idea last year from a couple different things, one was this rope lightdecoration at the Illini Union courtyard cafe that continuously changes colors. The other was from this huge bright LED sign at Irving Park and Sheridan in Chicago that is at some mechanic that uses the sign to advertise his parking spaces for Cubs games. I made this with Red, Green, and Blue LEDs, so I can make any color of the rainbow. This is done the same way your TV or computer monitor works, Red+Green=Yellow, Red+Blue=Purple. I threw in some ultraviolet LEDs in hopes they’d be nice like a black light but they’re more violet than a black light.Go to index 1 of 2 if you want to see more technical pictures.
