Is this how a wiimote works?
A friend gave mii a broken sensor bar to try and fix (just for the hell of it). I took it apart and was surprised to see that the only thing in it was several IR LEDs and a couple of resistors. My theory is that the sensor bar is not a sensor bar at all but more of a transmitter/light source for the wiimote. If the wiimote is the IR receiver and moves the cursor on the screen based its position according to the source it would then have to transit that data back to the wii via bluetooth. Is this correct? This would explain how the wireless sensor bars work and why sunlight messes with my cursor when shining at my wiimote.
