Two screws on the bottom

 

Inside view

The leaves

Some tin weights. Tin is now about $20 a kilo. In 40 years economical world supplies will run out and the price will rise.

 The coil

The solar cell showing over 1 volt. This is hard to do with only two hands. One is after all holding the camera.

 

The capacitor to store up charge till the pulse is sent to the coil to make the leaves move.

Here is everything all together.
