(...) Thanks a lot, Dean! Total electrical isolation is a good idea to achieve what I'm planning to do. I am trying to switch circuits of various Voltages (a 12V circuit at the moment in the form of an IR beamer). Do you have any information on both (...) (22 years ago, 28-Aug-02, to lugnet.robotics)

You certainly could use the optcoupler out of a computer mouse, but that wouldnt be the best may to do it. They wouldnt be designed with this application in mind, so you might fry the phototransistor if you used too much current, or too high a (...) (22 years ago, 28-Aug-02, to lugnet.robotics)

(...) In my "LEGO Mindstorms Interfacing" book published by McGraw-Hill I devote whole chapter (Chapter 4) on Electronic Switching techniques. I describe both input/output switching techiques using npn and Power MOSFET transistors to control RCX and (...) (22 years ago, 28-Aug-02, to lugnet.robotics)
