Styles which relied on feedback from a screw tapping on the magnets turned out to be problematic because exposing the magnets meant that the magnets were harder  to support.  The screw was always coming from the top or bottom,  exactly where the magnet support was needed.

Several ideas were appealing but the design to try next was one which was similar to a hanging bell. The idea was that the magnet spinner would rock on a pivot like before except it would collide with the enclosure when it faced north.  This version would still used the keyed post and spinner.

Sketch of new design

After sketching everything and seeing the design on paper it seemed possible that the magnets would be exposed to the post,  which could be made of brass,  and collide there instead of the enclosure. Glass was one possible material for the enclosure so tapping metal on glass, in the same spot, would likely cause damage in a short amount of time. The colliding post method should also for testing without an enclosure. Building a brass post in the correct shape will be a new challenge.

To do:
  • Model colliding post compass spinner
  • Print spinner
  • Build brass post
  • Make handheld haptic compass
  • Make compass work from pocket or necklace
  • Miniaturize
