    Hi All,

    I'm trying to figure what this component is and where I could get some
    of them.

    It makes a sound when it's shaken as if there's a small bit loose
    inside, I think it's probably a motion sensor of some kind.

    Any thoughts?

    What is the function of the hardware?

    Could this be a tilt switch? Did the board come out of an arcade game?

    It came out of a GPS / Bluetooth reciever, I think it's a motion/
    vibration sensor of some sort, to save battery, ie when it hasn't
    moved for a certain amount of time the unit will shut off. It probably
    generates a closed circuit when the ball(or whatever) inside moves and
    touches off 2 different terminals.

    Can't seem to find any examples of them on the web though.

    A lot of this stuff is custom made in Asia. In that case it would be
    next to impossible to find a datasheet.

    You say "probably". If the device just consists of four terminals and
    a rolling ball, then surely it wouldn't be too hard to confirm this
    with a multimeter?
    I searched for "rolling ball" and "motion sensor" and found this:

    I find the references to "test circus" and "rang of pin" a bit of a
    worry, though. :)

  7. Far more disturbing is the picture of two cloyingly sweet adlanders posing
    inanely in the picture on that site. Is the Western love affair with folksy
    advertising for EVERY last little thing so grossly out of hand that we are
    seen by China and the far east as shown in that ghastly parody? If so, it's
    time it stopped. I don't mean them. I mean us. Pass the sickbag, please.

    I find that Chinese web sites have an annoying preoccupation with
    Flash. They need to understand that visitors come looking for
    information, not entertainment. Or have I got it wrong?

  9. No. Although, if the pictures are informative it can help. Language is
    often a problem even where translations exist. Pictures and tables of data
    are usually like music in their ability to cross borders and language
    barriers. Can always do those with GIF's HTML, and JavaScript though.
