All the printed components were assembled. Long #6 (4mm) bolts and nuts were purchased to install in the bolt holes to erect a cage. Nuts were arranged to hold the lid at a precise distance above the bottom. This distance was enough to give the spinner space and allow it to rock back and forth when it faced north or south. In addition, the hemisphere on the lid kept the

The assembled unit was carried for an entire day which had a lot of walking. No haptic feedback was expected or received but the unit served as a conversation piece. The black/orange/brass look and moving parts intrigued peoples' attentions. There was a lengthy conversation with a physics teacher who enjoyed the thought exercise. Carrying the device and playing with it in a pocket helped to stimulate thoughts for the next phase. The movement is good enough to go ahead with the feedback portion which will be a new lid with a larger hemisphere and a screw hole so a metal screw can impact the metal magnets. The next revision of the spinner will also have a groove in the top so the protruding screw can pass around the spinner. Previously the thinking was to put the groove in the bottom but the top seemed the obvious choice after carrying it for a day.


To do:
  • Make handheld haptic compass
  • Make compass work from pocket or necklace
  • Miniaturize
