I'm always trying to figure out smart ways of using what I got. And I just added a neat indication of how many Wii Nunchucks are connected. And, I'm doing this by blinking the red LED. It will blink one time quickly when one Nunchuck is disconnected, and blink two times quickly if both are disconnected.
Quite neat and not so intrusive. Especially useful when in use and all of a sudden one Nunchuck might not work or if there is some other odd things going on. If the red LED blinks you can see that a Nunchuck is disconnected. The device shouldn't send any data for that Nunchuck if it is disconnected now though, so that shouldn't be a problem either.
Use your exercise tool such as a treadmill and a computer to enjoy exercising!
