A clone of North Paw, an anklet that tells the wearer which side is north using vibrating motors, was built in 2011. 8 vibrating motors from Motorola phones were inserted into plastic tubes, the tubes were inserted into a fabric strip 1 2 and the entire think with strapped electronics is worn on an ankle. No further experiments regarding orientation etc. were carried. As of 2015, there is some interest in replicating the experiment.

The hardware is a DIP AtMega328, TPIC6C595 shift register and HM55B magnetometer. It was my first MCU design and better things could be built today (starting with SMD parts for example).

Status

Prototype built and working, available in brmlab showcase. The battery is dead.
