Build your own GPS pet tracker with TinyDuino

If you’re a pet owner, then you know that there is no worse feeling than losing your beloved animal. If you’re a pet owner, then you also may find yourself wondering from time to time as to what they do all day. Fortunately, this DIY GPS collar will not only allow you track the whereabouts of your cat remotely, but can log its GPS coordinates as well. Meaning, you can download its location whenever you feel like doing a some pet-snooping.

Recently published on MAKE Magazine, Ken Burns shared his GPS cat-tracking collar, built around the ATmega328P based TinyDuino platform. The system is powered by a small, lightweight battery and equipped with a fairly “power-hungry” GPS and microSD card, each of which are enclosed inside an old Tic Tac container.

According to Burns, a small slot was cut into the case in order to allow the cat collar to slide through and the GPS module to sit on the back of a cat’s neck, optimizing antenna reception.

In terms of software, the Maker notes that he used an Arduino sketch running on the TinyDuino, which captured the raw data from the device and writes it to a text file on the microSD card.

“Pop out the microSD, put it in your computer, and you can open up the file in a program like Google Earth and see exactly where your cat was during the day, complete with timestamps.”
