IR tunnel?

[avallk]

We have a stereo unit in a closet - just because it was the best place
to put it. It's out of the way and works great. One problem however,
in order to control it, we need to keep the door cracked. I have been
looking at the IR repeaters and IR to RF units and none seem to work
great, unless you want to pay more than we do. Does anyone know if
there is something that we can use to repeat/tunnel the signal from
one side of the wall to the other? I thought about using a piece of
fibre, but that didn't work. The unit we have is an Onkyo TX-8011. It
is pretty amazing how little space is needed for the signal to get
thru. Not that I would install something this size, but would
something like a sun tunnel work? How about a peep hole, light you put
in your door to see who is on the other side? Prefer to do something
non-electronic.

Thanks
Ken

The Xantech's work well and are as reliable as anything else
in optically and/or electrically noisy environments. It's
important to keep in mind that *many* modern devices cause
optical noise in the range of remote control carriers, including
especially plasma and LCD TV's, and some modern lighting
dimmers.

Don't mean to scare you off your project, but just a head's-up
that the receiving sensor may very likely need to be sited
after some experimentation. Don't stick it down and drill
extra holes without some testing. The Xantech IR emitters
light up a nice bright red when excited, to help!

Me neither. Would be a fun project for somebody with a bunch
of fiber optic tubing laying around, and a fair amount of
time and energy.

Off the top of my head, I'd guess that the toughest part
would be making the intake manifold.

All the best fortune,
