I had a revelation about why I got so much interference from the pendulums. Seeing them in action made it clear in a way that was difficult to visualize without a physical model. I kept designing swinging arms that extended above the spinning compass so they generated a lot of momentum before striking something when facing north. The problem was that with such long arms, the pendulum could smack the case at any angle.
I revised each part. I started with the spinner, which would use some new rectangular magnets I received. The right angles made encasing them a different battle since I needed to hold them from all sides, whereas I could secure a stack of cylindrical magnets with two flat wood pieces. I resized the interface layers and caps based on the previous work. The most fun was creating pendulums. I ranged from centrally balanced to one requiring a nut and bolt to keep it oriented.
