I have assembled another Jeenode and and an Infrared plug:
It appears to work fine with the ir_repeater Jeelib example. I now have to make it work with my LG TV, LG AV Receiver and Virgin TiVo box, so that I can use it with OpenRemote. I did this with my previous version, so it should just be a matter of using a different Arduino library.
This version has two LEDs on it. I am hoping that I can point one at the TV, and the other at the receiver and TiVo box.
