I'm currently working together with some friends on a school project, which involves setting up a working wiimote whiteboard.

We have already connected it to an adapter so it runs off the mains, but now our wiimote behaves strangely:

Connecting via bluetooth works okay, but when I start the wiimote software (the one by Johnny Lee, v0.3), the wiimote emits some kind of screeching sound, which only stops when I disconnect the wiimote's bluetooth connection completely. Does anybody have any idea what has caused this strange behaviour?

Testing it with batteries is a bit difficult now, but the problem definitely didn't occur when it was battery powered.

The adapter is set to 3 V, but we'll check it with a voltmeter next time.

Though come to think of it now, it might well be possible that the Wiimote we've got is in fact a fake, which might also explain the low FOV; in that case we'll try to get a new, original one, so it won't be worth bothering with this problem.

Thanks for the help anyway.
