A belt that buzzes north

This repo contains Arduino code for a wearable compass, consisting of a belt with a number of mobile phone vibration motors mounted along its circumference. As the wearer moves around, the motor closest to magnetic north buzzes. According to this WIRED article, through the miracle of brain plasticity, this will give the gift of an amazing sixth sense of direction.
