Now that we know that the Nintendo Wii “sensor bar” doesn’t actually sense anything, rather just provides an infrared point of reference for the Wii-mote, it seems like it would only be a matter of time before we’d see a cordless variant.
For those of you who don’t want to run a cable from your sensor bar to your Wii, or want to place your Wii at some distance from your TV, the $25 Wireless Sensor Bar provides a battery-operated alternative to the version that ships with Nintendo’s console. The replacement sensor bar runs for about 48 hours on a single Alkaline 9V battery. An LED indicator lets you know when the bar is turned on. The manufacturer claims a 3 to 8 foot range, which is in keeping with Nintendo’s spec (although my own tests have shown that the stock Wii-mote /sensor bar combo works pretty well from greater distances, especially in a dark room.)
