    How's this for a project for someone clever.
    A picaxe with a GPS and transmitter that fit's into onto a dog collar
    which transmits its position back to a reciever, so when your dog runs
    off you can find it easily. Could also be used with kids in shopping
    centers or attach it to cars or motorbikes to find them if they're
    stolen (depending on the range of the device), Could even work through
    the mobile phone service maybe.

    Commercial mobile phones with gps are available now - great idea and
    parents feel more secure knowing exactly where their kids are

  3. OK you can receive GPS locations.

    How will you transmit the coordinates back to base?

    If you are out side GSM mobile phone range - how will you transmit... if
    your little doggy runs off in the country side.

    How far will the transmit power need to go (distance)?

    Hw often will you transmit the coordinates?

    How long do you want the battery to last?
    (range, Tx power, Tx duty cycle and battery capacity will effect the battery

    What is your target price for such a device?

    It's very easy to have an idea ... but much harder to put in to practice....
    with all the practical factors.
