Has anyone here built (or bought) an IR transmitter/receiver for their PC? I was thinking about this today, and there's a couple things I'd like to do. 1-I'd like to be able to capture the signals from my individual remotes for backup purposes. I use my Sony learning remote for everything, and I was worried that if I ever needed to reprogram it, the original device remotes would be lost or not working (or just hard to find). If I could capture the signals though, then theoretically I could reprogram my remote by just having the PC retransmit the IR data. 2-I have a Creative Nomad Jukebox 3 that has a built in IR receiver, but Creative has since stopped selling the IR remote. I'd like to be able to control this with my learning remote, and figured that if I could get a transmitter for my PC, then I could either find the codes online, or experiment with different combinations to try to determine them myself. I'm tempted to just try to build my own from parts from the electronics store, but that seems like it might be more effort than it's worth (especially if I want to build something like a USB interface), especially if there's a readily available commercial product that does what I want. Has anyone ever tried anything like this before?
