DIY HACK – PC controlled Christmas lights

This has been around for awhile but it’s a good DIY Hack on how to control Christmas Lights using
your PC.

My main goal was to have a small box that would easily control many Christmas light circuits from one parallel port. I specifically wanted to use the parallel port so I could easily plug it into any PC. I did not want to have to open up PC cases and remove boards every time I wanted to use a different PC. I also did not want to pay $400 for a 192 output digital IO board and cables when I could make something to handle more circuits for less money. The box needed to be expandable with the addition of a little more hardware. Lastly, I wanted to prove to myself that I could do it.
