| | | | I use a laser diode to send voice signals in my class. I modulate it with a transistor and set it so approximately 3 volts DC is dropped across tht laser diode. I would recommend at least a 100 Ohm resistor in series with the diode. It is polarity (...) (26 years ago, 8-Feb-99, to lugnet.robotics)
