My wife is a huge fan of all things Harry Potter so I decided to make a Weasley Clock for her. Tasker collects location information based off connected WiFi networks and posts that to the particle.io API to set the pointer locations. As is traditional on Reddit at least, finished product first.
A coaxial servo motor controls two custom made clock hands to show the physical location of family members.
Two servo motors control independant shafts that are coaxial with eachother.
Motors wired up to the motor controllers
Motor controllers wired up to the Photon
Testing on a stand in clock face while I try to figure out what to use
