    This is something I built a while ago. I don' think there is anything similar on the web..

    If interested in more details on construction etc. just ask :)

    I had in mind to add a position detector with an optical sensor (found in old computer mice) but I never implemented it.

    It would be interesting if someone is to add an automatic switching circuit ;)

    This seems to be new. Has it ever been done before?

    The idea came to mind after I saw the simple compass on floating corks etc.. science experiments. :)
