What's involved in making an infrared transmitter and receiver that
could be used for an audio link over 4 - 5 metres, such as is used for
remote headphones. Mono would be a good start, but stereo would be
even better.

I'd like to build something along those lines. Are the IR components
readily available, and is any special focussing of the IR beam
required?

Could someone give me a steer to a web-site(s) that might contain info
on such a project.

Thanks MikeN
