Screen Saver Power Switching


This is another power control hack along the lines of the serial controlled power outlet. Instead of only managing a printer, [Brent] uses the IO lines of the parallel port to drive some SSRs in order to turn off all of his peripheral devices – think lamps, speakers, scanners, etc. He posted the whole thing over on instructables.

  1. Worked for a company that did something similar in 1985. using S100 based computer to control a machine. Used a parallel port (Printer port)send a binary word To the port ie 10001101. each 1 on the output turned on a device, each 0 turned off. Easy to implement, worked great.
