    Every year, Shelly the tortoise gets lost or manages to escape the garden.
    It can take days to find her. I would like to build a locating device so
    that I can track her down.
    The basic requirements are:

    a) that the 'transmitter (transponder?) on the tortoise is as small as

    b) that it can be made by an electronics numpty. I have basic soldering
    skills, and can eventually work out a circuit diagram.

    Can anyone point me in the right direction?

    There are tons of these on the web. Just google "rocket tracking
    transmitter" or "model airplane tracking transmitter". There are many
    circuits and kits available.
  3. Why not just paint her bright green?

    I did think of putting an led on her so I could search at night - but she
    has a tendency to bury herself in the undergrowth - hence I'm going down the
    raidio route.

    Thanks for that Richard, I have looked briefly at these - but the ones
    I've seen so far seem too big for a single Kilotort.

    How big is Shelly?

    About 20cm (8") long - perhaps15cm wide (6"), 10cm (4") high, weighs 1Kg.

    Glue a key finder on her back.

    Good call DF! I think this is the best idea. You will need to take the
    responder apart and waterproof it. I gets around the problem of battery
    drain since these devices draw no power until activated. Plus it will
    take a minimum of electronic knowledge.
  10. Try seeking some advice from the New Zealand Department of Conservation
    which uses these things to keep track of kiwis and native parrots. You will
    find their web site easily enough. Then start emailing.

    Green? Notwithstanding painting a tortoise's shell is very very bad for
    the tortise, if I _could_ find safe tortoise paint, I'd go for blaze
    orange. ;-)

    Then, you can find her at night with a black light. ;-)

    They must be veeery small then 'cause I've never found one in the many kiwis
    I ate. And now they track my shit?

    I know you guys were tracked, especially abroad, but I thought they use your
    cellphone for that.
