Tyranny of the Arbitrary

Hardware

This project aims to recreate a simplistic version of a fitness tracker. Instead of being made for humans, however, this device is designed to be worn by a dog. The garment is a collar made from fabric and garment interfacing. The collar is constructed in such a way that two the two pieces of fabric are sewn along one of the long edges and can open like a book. The LilyPad and accelerometer are sewn to the inside of the “book” and are connected via conductive thread. When worn, the top flap is folded over the electronics, and snaps to the other piece of fabric to provide protection. In order to record the data collected from the accelerometer, a Sparkfun OpenLog with a micro SD card attach to the FTDI connector. Data is stored on the SD card as a text file. At least this is how the hardware setup is supposed to work. There were some problems recording data to the OpenLog. Sparkfun customer support was not able to help me resolve the issue. Sparkfun was kind enough to test another OpenLog and sent it to me. However, I was unable to record data with this hardware as well. As such, the LilyPad was connected to a computer via the USB cable. Data in the serial monitor was copied to a text file.
