Cold cathode art piece controller

[Andrew] built a light box for an exhibition last year that displayed different colors statically. After showing it off, it went unchanged but future improvements remained in the back of his mind. Recently, he pulled it out again and hacked together a controller to drive the colors individually.
He’s actually reusing some of the hardware he built for a different project. At its core is a PIC 16F628 that actuates the lights using relays. In this case, only four of the eight on the board are used to control red, white, blue, and green cold cathode tubes. The video after the break shows the device randomly rotating through different patterns. This is a nice start to making the piece more interactive and we can image adding web-controlled color changes, or perhaps some Daft Punk inspired functionality.
I’m actually shocked that I liked the effect, nice work.
