Wiimote sensor?

[Oehr]

you just need 2 infrared emitting sources. those sources can be a two candles or simply two (or more) infrared LEDs(powered by batteries or usb).

here are some links:

the wii sensorbar doesnt "sensor" anything. it just emitting infrared and the infrared camera build into the wiimote detects the two glowing lights. thats all.

you only need a bluetooth stick to connect your wiimote to the pc.
