Pendulums continued

I finished the pendulum with the wooden balls.Of course Version II wasn't the last,the record player arms were still used though.So you might call it VII.3.I didn't knew if I should point the arms downwards or upwards,so decided,can you guess?,to have one upwards and the other one downwards.
I used one,big,solar panel to power both circuits.In the pendulum bobs are 3 1/2 " diameter magnets each.
