The machine photographed above is a reproduction of Nicola Tesla's early 1893-1899 High Frequency Electrical Oscilator designs. These machines are table top power supplies capable of transforming low frequency 120 volt alternating current or 3.3 volt direct current into high voltage high frequency impulse currents in the order of a quarter million volts at threehundred fifty thousand cycles per second while drawing no more than 1/40th of a horsepower.
This table top power supply is a useful instrument for experiments, and explorations in induction, capacitive, particle, plasma, x-ray, laser, heating, electrolytic and transmission physics.
The aim of this project was to reproduce the famous sheet of light photographs demonstrated and photographed by Nicola Tesla over 125 years ago (shown below). The photographs above are the first color reproductions of those origional photographs.
Voltages measured typically range between 125,000 to 150,000 volts with nothing attached to the terminals. With careful tuning of the knob and apropriate capacities fastened to the terminals, 250,000 volts is achievable.
