When I used to watch Blue Peter hibernation involved putting the tortoise in a cardboard box full of newspaper and putting that in the garage for 3 months. Looking at the program records a number of tortoises died in hibernation and knowing what we know now, that’s not surprising. There’s a lot more too it than putting the animal in a box and hoping for the best.
To successfully hibernate the tortoise needs an exact temperature range as well as regular checks. Higher than 10c at the tortoise will wake up and must promptly be removed (or starve). Below freezing will kill the tortoise. So with the weather being what it is a more precise method is needed than the box/garage.
A popular solution at the moment is to use a fridge set to the ideal temperature of 5c. Fridges, however are large and expensive and using the food fridge is not recommend for hygiene reasons. So I’ve decided to build a custom tortoise hibernation box using the Ar
duino microcontroller. Not only will this be able to control the temperature but with a network shield I’ll be able to have the system email me when the temp moves outside thresholds.
Tippy isn’t being hibernated this year, it’s best to own the animal for a year so you know it’s 100% healthy. So I have plenty of time to build and test the unit. My plan is to use a thermal couple to monitor the temperature with a Peltier/heat sink & Fan arrangement to cool the box to 5c. A standard Ethernet shield will provide the email capability.
First task is to buy the hardware and search the internet community for existing projects that I can adapt to my needs. I also have Jame, a professional physical computing nerd to help me out with the code.
This should be a fun little project with a real world application.
