Yes, that is what I'm trying to do. I think that this would eliminate interferance. Though the price is tethered operation. I guess it doesn't really have to be a coax. It can just be an RCA A/V cable right? Or how about a single wire! ---...--- (...) (25 years ago, 4-Aug-99, to lugnet.robotics.handyboard)

I've been using the Miniboard to send and receive IR messages among other things. I find that the board is right on the edges of being fast enough to generate the 40KHz carrier and thus, I don't use it that way. Rather, I use the Miniboard to (...)
