Well, my friend is currently borrowing my Nintendo Wii otherwise I'd already be on top of this!
The idea is that the Wii's Sensor Bar has 10 IR LEDs (I don't know their exact 'brightness'), 5 on each side of the sensor bar that is covered with the black glossy plastic. It emits IR so that the Wiimotes can calculate their orientation easier and not have to rely on the accelerometers completely (mostly for instantaneous position/orientation rather than over time).
Anyhow, I was curious if the sensor bar would set off a laser false on any of the top RDs. I'm assuming it would since a TV remote can and I'm going to assume that 10 of these (more than likely) 'brighter' IR LEDs surely could.
What I am getting at is that Nyko sells a wireless sensor bar for the Wii, which I assume has the same concept except it uses batteries instead of a direct wire to the Wii itself (however, this could be a relatively easy electronics project if you don't want to shell out the gross amount of cash). Although I've already entertained the idea of putting that on the dash and seeing how many RD owners get a false and freak out, but the idea was could that also serve as a really really makeshift jammer?
I'm sort of ignorant of how laser jammers work other than (from my understanding) they overload the response back once they detect incoming IR.
