Copper and brass magbot pendulum

This pendulum is in the making at this moment.The wooden base came from an old amplifier,on it will be a stand made from copper pipe and brass fittings.The electronic circuit will be housed in a small aluminium box which sits next to the stand.
I'm planning to make this with three different pendulums:a string,a chain and a solid rod.
Edit,May 14th,it's ready!:
