I have focused on attaching a pendulum to the spinner, which may be backward. A pendulum can unbalance the compass, adding unnecessary complexity to the most sensitive component. I conceptualized a way to use the spinner as an "anvil" and strike it when it faces north. Writing about that idea just now reminded me that my design is flawed because it can hit the south side of the magnet. I guess that is a win for journaling, but I spent a day designing a flexible "hammer."
I designed a spring-loaded mount to wobble a brass machine screw, and when the magnets passed nearby, ie, facing north, they should collide with a metallic twang. I shortened the sides and top of the spinner enclosure to expose the magnets since their force would hold them in place.
New parts in CAD
I cut the mounts, but they were fragile. I broke a couple of them but managed to make a pair of the 10-degree model, which held a plate nearly parallel to the spinner's path. I did not do a good job scaling because they were too tall for the enclosure, stuck out too far, and held the machine screw too high. I will need to revise the spinner if I continue with this design.
Not a perfect fit
