Adam, I used the one off of http://www.lirc.org/receivers.html Works
great. I had a problem finding the reciever ic locally and went with
one of the Panasonic ones. Got it from digikey. The one issue I had
was figuring out which pin was which on panasonic one, but I used some
aligator clips to make figuring it out easy enough. I did not need a
microcontroller.
For the transmitter circuit, build the "simple" one on the transmitter
page. You only need one resister, one diode, and one ir transmitter
diode. All in all about US$1 worth of parts. I tried to build the
"improved" xmitter circuit 2 or 3 times and never got it to work.
