Parallel Port Lighting Control

["Mark McCall" <lists@xxxxxxxxxxxxxxxxxxx>]

Hacked Gadgets brings you schematics and photos of Raphael Assenat's
home
built, opto isolated lighting control system...

"I had been thinking of controlling my room lighting using my
computer. I
bought some triacs and opto couplers to do this. I drew the schematic and
built a prototype. Everything worked well. When I was wondering in which
case to use, one of my friends suggested that I could use my computer
switch
box."
