I would be interested in any schematics you would be willing to give up, maybe even a little theory behind operation. I must admit I am lacking quite a bit in the communications area. Thanks, Joe Hoffmann E-Mail jhoffman@it.sait.ab.ca (...) (26 years ago, 4-Dec-98, to lugnet.robotics.handyboard)

That will only allow one half of the conversation. I suppose you could run with two kits, one receive, one transmit, both tuned to different frequencies. Another suggestion might be one of the cordless, battery operated intercom system units. Most (...) (26 years ago, 4-Dec-98, to lugnet.robotics.handyboard)

Has anyone used Apple computer microphones with their robots. The mic seems to have a left and right channel. It has a circuit board inside the case. I don't what the circuit actually does.

That's a hard one because you have to have sufficient gain from the robot microphone to hear someone 2 to 8 foot from the microphone. Usually communication equipment limits their microphone gain on purpose to exclude background noise. You have to (...) (26 years ago, 4-Dec-98, to lugnet.robotics.handyboard)

The Polaroid Sonar board requires a supply voltage less than 7 volts.
