The sensor bar isn't actually a sensor, just two IR blasters that the cameras on the wiimotes use for positioning.

You can use any two sources of infrared light instead!

The sensor bar is ACTUALLY not two IR blasters, but two sets of 5 commodity IR LEDs!

Before I knew this I had someone pull out their lighter and point the remote at it when our sensor bar died. Took me a little bit to figure it out.

I blame Nintendo for calling their "2 lights bar" that doesn't have any sensor a "sensor bar".

If I were to place you on a team in my company, I'd more likely place you in engineering than marketing :)

It's a bar that the sensors need to find. It's not optimal but it's a fine use.
