This version is much more portable. The key is the In & Out connectors.  This allows for me to move an IR PCB from case to case and only requires the construction of a new cable for input and output.  In these images I created a Out connector that will accept the 3/32" jack for the bundled Hauppauge IR Reciever. The PVR-250's are in the backend so the IR modules are usless bacause the backend is in my closet.  With this little mod I can now use the Bundled IR Receiver on my [http://www.mythtv.org MythTV] Frontends.<br>

Homebrew rev 3

I got tired of making a custom IR Receiver for every case/mobo combo, so I came up with this. This version is much more portable. The key is the In & Out connectors. This allows for me to move an IR PCB from case to case and only requires the construction of a new cable for input and output. In these images I created a Out connector that will accept the 3/32" jack for the bundled Hauppauge IR Reciever. The PVR-250's are in the backend so the IR modules are usless bacause the backend is in my closet. With this little mod I can now use the Bundled IR Receiver on my MythTV Frontends.

Hauppauge IR Pinout

If you are like me and have your Hauppauge Tunners in your backend, then the included receiver doesn't do you much good.
Fortunately you can use the included IR receiver along with the above LIRC Homebrew Serial device.
