Made this thing for my old IPAQ 110. Didn't work back then, doesn't work on my n900 now(used wav files from http://www.rtfms.com/episode-4-turn-...sal-remote.htm )

oo and this will make a transmitter only! , not receiver, so it's useless for n900 since we already have one.

The best solution would be to buy one of http://www.lirc.org/html/table.html#@hw-usb
those and compile module for n900.
