I assembled the new parts, starting with the case. This time, I made it two levels high since I do not have long pendulums. I may expand it later because the rectangular magnets can stack without wasting space, unlike cylinders. I built a spinner, but I forgot to add an axle. I could not find a brass rod in the correct thickness for this revision, but I included a steel nail that will interfere with the magnets but should be OK for this trial.

I hung the three-spoked pendulum off the side, but there was too much friction for something so light, and it is balanced, so it does not want to spin. I should focus on unbalanced models and reducing friction.
REV4 assembled for testing
