Parallel port relay for playing with real world gadgets!
I've finally connected a relay to my parallel port! I got the circuit design from here. I can use the relay to control almost anything in my house. I have combined it with my gesture recognizer to allow me to control things with a laser pointer! Its fun. Using this with motion detection could also be a good idea. The computer would turn on lights whenever it senses motion. Anyway, check out the video above. I'm controling a table lamp with my computer. 
I guess I could've connected upto eight relays, but I wanted to keep it simple. Besides, I might end up using a bluetooth relay board later on (or maybe even X10). :)

amazing work.........dat's automation...at it's real best....
Keep on doing this great work..
Sweet you could (its been done before) control lights as a windows visulisation (diffrent lights turn on and of in time to music. Althought you would probally need to use opto-isolators.
Cool idea! :)
yes opto interface is the best method to protect parallel port.
i made a opto based relay board to switch on spindle for my CNC milling.

Cool. You could control your lighting from batch file commands when you are about to start a game up. You know, ... dim the room for action, lol.
