You’ve likely seen impressive sequenced Christmas lights in videos before. Very often, though, these setups use proprietary systems. Here, Processing makes it quick and easy to code lighting effects in a friendly, open-source environment. And, naturally, if you think you might want to do something like this and don’t want to wait for Christmas 2009, I can imagine quite a few other interesting lighting applications.Creator Jack Kern describes the project:
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 (processing.org). 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!
