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.

So it seems I've hit the magbot pendulum phase of my projects with 2 being build right now and a couple of ideas floating around in my head........
The most recent one started out as an all wooden one: a few weeks back I bought some wooden balls to be used as pendulums.Then I thought it would be interesting to use the wooden balls as a reoccurring part in a magbot pendulum.Version1 was: a large size ball on a stand,a wooden dowel inside it and at the end a medium size ball,then two wooden arms with small size balls at the end and
But I found out I hadn't enough material to build this(the aim always being to use recycled parts as much as possible)and one arm just didn't look right.
So,enter Version 2:up to the medium size ball it's the same as V1,the two wooden arms are replaced by the arms of a record player stylus.With the advantage that they have a nice bend.
