radio tracking a tortoise - HELP!

Mar 05, 2006 13 Replies

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 possible.



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. richard

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.

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. Richard

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.

They have everything from plans to complete units.

Good Luck! Rich

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. ;-)

Cheers! Rich

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

;o)

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