Wii Sensorbar

That black ugly thing you have to put on or unter your tv is called sensorbar. That’s why I thought it would have some kind of sensor in it. But, it doesn’t. I opened one today. All that it is is some infrared leds and a couple of resistors. It’s just two infrared lamps. All the recieving is done in the wiimote. You could put two candles onto your tv and  it will properbly work in short distances.So how does this work? The wiimote recieves the two beams of infrared light and depending on how much light it gets from one side it calculates it’s relative position. It doesn’t care if it’s candles, open fire or a so called „sensorbar“. The sensorbar has special leds with a high infrared ouput so it works best and over large distances But you could use something else or build your own sensorbar, for example if you brake yours. Or, if you have friends over for some competition build a little infrared spot you turn on when you’re not the one playing. I guess you’ll win any game.
