This GPS Dog Collar by Adafruit Tracks how far your Dog has Walked. This is great to make sure your dog is getting a healthy amount every day. It is based on a small microcontroller board, a GPS module and a cool OLED display. Becky Stern shows us how she put together the project in the video below. That ribbon material that is used to make the electronics look nice is quite interesting since it has 2 metal wires built into the outside edges, I am thinking that it would make a great way to run power to the project in a new design.
