When the cat chewed the cable to the sensor bar of the Wii console, a man has discovered that he can simply replace with two candles. The sensor bar is connected to the Wii, but only to the power supply as well activates two infrared LED. These LED used by controls to determine their position in space, and then send this information back to the Wii. So if you have two independent sources of infrared radiation, you can easily replace the bar. Waxes emitting infrared radiation and just operate as an LED.
