This particular schematic's not finished yet; jt is just a regular low-powered transformer able to oscillate from transistor, output from jt goes to power the coil which kicks the magnet. Circuit to coil's open by its own transistor when magnet passing by the coil; it's a common schematic for 9V battery powered "kickers".
Tiny circuit is a couple transistors and capacitors to pick up some juice from coil, open tr-r, and to kick magnet while its flying by.
Yes its very interesting about how long its running; after power to jt is switched off the pendulum making couple even more intensive swings and slowing down to running level from its bttry. Seems like after jt switched off some more back emf getting into cap giving a little more voltage.

This is very interesting. I am very curious about the circuit.

great work, 5 stars!
could u post a circuit of this?

The battery will run down and it will stop. You can try the same experiment with a charged capacitor.

It surely will, same like capacitor will discharged.
But...if you do it in pulse mode, giving enough time to recharge the cap it may lead to somewhere.

This back emf staff's very intriguing thing...

Nice demo, how long does it run for?

Interesting demonstration. What is the tiny circuit board between the pendulum and the JT?
