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.

Frank found a real gem here! He won't tell me when he gets
it up and running, because he knows I'll fly there and will never leave!! |

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. |
