Synapses:

I had an idea to create a desktop widget that can send the IR commands needed to a Nikon DSLR so that you can use the remote shutter. That one came true and its very neat.

I since then started to mess with Irreco and QTIrreco and wanted to see what using the N900 as a universal remote is like.

Problem: None of the 3 TV's in my house are in the remote database and there are no similar devices so I cant add the remote commands.

Solution: Add them manually to the N900 and then if you wish upload them to the database for others to use.

Problem: The N900 only has a IR transmitter, not a receiver, but it dawned on me, many of us already have an IR receiver device and we already know how to connect it to the N900!

Follow along with me, the Nintendo Wiimote, the front of that remote has an IR camera and can read sources of IR light, so I am pretty sure it can also read the signals sent out from a remote device. If that is the case we just need to create some kind of program to interpret the signals and then be able to save them to a file/database so that we can use a "learning mode" with the N900 to teach it the commands of any remote you have.

The wiimote already pairs with the N900 via Wiicontrol, so while we may have a long ways to go at least this is the idea and concept. Anybody think its possible?

I've been thinking about how to get around this problem myself recently. If that can work, that's a good idea.

Interesting idea. It is probably worth talking to the upstream lirc people (https://lists.sourceforge.net/lists/listinfo/lirc-list) to get their ideas about using a Wiimote as an IR receiver.

Ir commands come at ~38khz. I seriously doubt that a wiimote camera can capture more than a few hz.

Also iirc the IR image can't be accessed directly on the wiimote, just the relative (spatial) motion.

That was my only concern as well, but did not know if that was due to current limitations in how the wiimote is programed to work or the hardware.
