2024-06-11 (Tu) GrinderCompassMKIII Cage concept sketch

The previous compasses relied on the relatively heavy spinner banging into a light obstacle because it would not restrict the spinner's movement. The problem is that tapping something light provides little feedback. The new revision may allow the spinner to collide with an outer shell and keep spinning.

The concept was similar to a microphone shock mount where the central hardware, the magnet spinner, was suspended by elastics. The magnet had a cage with cleats outside to catch the elastic. The outer cage had internal cleats to catch the elastic, and when they sat 45 degrees apart, the cages should be nested without touching. I have not drawn the feedback hardware or spinner beads in this sketch.
