I looked over the lirc stuff last night after reading your mail and
noticed this, then tried plugging the eye into my mic socket - the plug
is slightly smaller :-(

my electronics skills are probably not up to that...
buy a pre-assembled one

I found this last night, read through it and decided that I wanted the
internal EPIA model. Unfortunately, Thomas' write up says that this only
works for 5v COM2 ports, whereas mine appears to be 12v - so I have
mailed him to ask him whether he has a solution to this.
or get hold of a USB IR receiver.
I'm trying to keep everything within the case, which has a nice grille
at the front behind which I intend to position the eye.

If its changing a plug, I am probably up to it. Reverse engineering a
circuit is way beyond me !!

I see - the homebrew receiver definitely seems to be the way to go. I've
got a number of remotes at home that I could use...
Thanks for all the guidance, it is much appreciated.
