I have the
Silverstone LC-10-M case, and it comes with an IR receiver built into the VFD
on the front of the case. Unfortunately, it is USB header IR which I
understand does not work with LIRC. My motherboard does have an IR
SIR/CIR header. I was wondering if anyone knows of or has a built a USB
to IR header adapter ?
I suppose I would
still need a USB pass through as well to drive the actual VFD
display.
Thanks,

Receiver
I use the motherboard irda port,
in SIR mode. Works like a champ. Almost the same field of effectiveness as my
TV, which could probably be improved if I got it closer to the smoked glass
front.
I built the darn thing from a
simple IR receiver (Radio Shack 276-640) and two capacitors (10uF and 100nF)
between VCC and GND. It's on a small perf board, but if you're clever with
your soldering, it could be done without. The hardest thing to come up
with the the cabling. I happened to find some scrap from work, but you may
have to find something that can be chopped up to plug into the motherboard
irda header. Check your motherboard manual for the pinout of the
header.
I looked briefly on Maplin's
website, but was unable to find a good equivalent for the IR recevier. It's a
pretty generic part, though, so one would think that somewhere in the UK there
would be something close to this. Of particular importance is the operating
voltage (should be wide) and the center frequency (around 38kHz). It's
basically made to receive IR signals from a home remote
control.
After that, it was just a matter
of turning the port on in the BIOS (replaces a serial port) and
adding the following line to make.conf before I built lirc. (Mine is a Gentoo
system. For others you'll want to figure out the proper way to build
it.)
LIRC_OPTS='--with-driver=sir
--with-irq=3 --with-port=0x2f8'

[mythtv-users] Internal IR Receiver
Has anyone implemented an
internal infra red receiver for use with lirc? I want to have a unit
internally housed in my myth box, modifying the front of the case to allow
the signal through. Anyone achieved this or know of a site with some
information on parts required? I�m in the UK, so I guess maplins will be a
source of parts for such a venture.
Cheers
Rich
