Christmas lights color organ

Home Music

Game programmer Jack Kern took time out from coding pixels and turned his house into a holiday color organ using Processing

This is my first attempt at a computer controlled light show for our Christmas lights. Everything was DIY including the software which I wrote in Processing ( Simple wiring using parallel port output to switch some 120v relays. Only 8 channels, 1500w per channel max. Next year I’ll be trying for many more, dimmable, LED’s and DMX control of our RGY lasers!

Definitely looking forward to next year’s yuletide laser-blast fest! [Thanks to Creae Digital Motion for this one]
