Re: [mythtv-users] Internal IR Receiver

[Shane Hetzel]

Rich,   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'   -Shane         ----- Original Message ----- From: Richard Holroyd To: mythtv-users@mythtv.org Sent: Wednesday, February 02, 2005 9:48 AM Subject: [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 This message has been checked for viruses but the contents of an attachment may still contain software viruses, which could damage your computer system: you are advised to perform your own checks.
