  | Pancake Tesla Coil Operated with Carpentier Style Interrupter: Electric Autographs
This coil was producing snake-like strobing negative discharges 4-5" long, interposed with very distinct branching positive discharges 3" long. Current consumption: 100 watts at 110VAC. |

  | Lichtenberg Figures in Crookes vacuum
These figures are unfortunately unclear due to the near
impossible circumstances of trying to photograph them -
they were created using a burned out Edison bulb with
a straight filament. The filament heavily bombarded
was spinning around the tube, and when it hit the glass
formed rapid moving Lichtenberg Figures.

 | Tesla Oscillator for Ignition Purposes:
Patent 609,250
A Tesla Coil for igniting gas engines - a "Tesla" ignition coil. |
 | Tesla Oscillator with Mercury Interrupter:
Patent 609,248
This patent utilizes a liquid-to-liquid "make", with an insulating
disk used to separate the liquids for the "break" duration. |
 | Tesla Oscillator with Mercury Interrupter:
Patent 609,247
This patent utilizes liquid-to-solid interruptions of a
centrifugal ribbon of mercury to make and break contact
with a fan blade. |
 | Tesla Oscillator with Mercury Interrupter:
Patent 609,251
It's not perfect, but these still took forever to draw! |
 | Tesla Oscillator For Producing Ozone
Here are some 3D renderings I made of a famous Tesla Coil. |

 | Powerstats!
We've recently acquired 3 large 3-phase variable transformers. ("Variacs" type transformers, manufactured by Powerstat)
Divided they form 3 single phase autotransformers. We need only
1 unit, the other two are FOR SALE! |
  | Reproduction Thompson Plaster Spark Gaps
These gaps are unique in that they are stationary, yet adjustable through the use of a sliding arm that short circuits the number of gaps not wanted in the circuit. They are ideal for voltages from 3,500 - 25,000V or more. |
