Perhaps a near-IR LED with a 555 and a 9V battery would work for the
"transmitter"? Somewhere I have some plans filed away for something
similar. Depending on the output of the LED, and sensitivity of the IR
transistor used by the detector circuit, you might not be able to key
while making a turn, but then how often would you need to do that?
