Zamboni pile
The Zamboni pile (also referred to as a "Duluc Dry Pile") is an early electric battery, invented by Giuseppe Zamboni in 1812.
A Zamboni pile is an "electrostatic battery" and is constructed from discs of silver foil, zinc foil, and paper. Alternatively, discs of "silver paper" (paper with a thin layer of zinc on one side) gilded on one side or silver paper smeared with manganese oxide and honey might be used. Discs of approximately 20 mm diameter
to deflect the leaves of an ordinary electroscope. By bringing the terminal knobs of the pile near each other and suspending a light brass ball between them, Zamboni devised what was called an electrostatic clock. The device is so named because the ball oscillating between the knobs looks like a pendulum.
In the Oxford Electric Bell experiment at the Clarendon Laboratory at Oxford University, the terminals of what is believed to be such a pile are fitted with bells that have been continuously ringing since the device was set up in 1840. Note
