I've been thinking about how I might replace the RCX's IR communication with
something that doesn't require line-of-sight, eg using RF. I'm not much of an
analog hardware guy so I thought I'd ask about the feasability of it first...
I'm considering replacing the IR tower with a serial RF transceiver connected
to the serial port of the PC, eg along the lines of
http://www.connectionlab.com/elmo/ (which uses the Handyboard instead of the
RCX). On the RCX I'd have a similar circuit but the serial in/out connected to
an IR LED and phototransistor directly in front of the RCX's IR window to
convert the serial RF signal into a serial IR signal for the RCX. Sound
reasonable? What sort of pitfalls should I look out for?
Thanks,

| (...) This sounds complicated. I'm not sure if I'd want to go hacking into the RCX, but if you have an idea and a good idea of how to make it work, more power to you. I'd just like to point out before you get started that the infrared communication (...) (23 years ago, 16-Jan-02, to lugnet.robotics)

| There are devices sold by Radio Shack/Future Shop/etc called (i think) "remote extenders". Basically, they have 2 pieces. 1 is an infrared receiver and radio transmitter, and the other is a radio reciever and ir transmitter. I think they are one-way (...)
