Jacobs Ladder
A Jacobs ladder is an arc that forms between two upright electrodes that are wider at the top. The arc starts at the bottom and rises with the heat of the arc becoming progressively larger until it “breaks” at the top. It then reignites at the bottom to start over again.

High Voltage Halo Effects
High voltage halo effects are done with a long exposure of a rotating spark with a colour filter.
Here are some of the effects that are produced by long exposures in a similar manner to the Eye of Sauron effect but not using a Tesla coil.
The photo above shows the “Sombrero” . Well it was meant to be a crown really. Note the reflection in the stainless steel ball which shows the sombrero as well as the flash and my wife and son operating the equipment.
Note that as in all my photos there is no “photoshopping”. The pictures are all single shots and effects are produced with long exposures. Here’s how this one is done:
The HV supply I wired to a rotating setup that holds the electrodes.
The electrodes which will rotate around the ball (or my head) and on a long exposure with appropriate orange filter which is removed before a flash to give “normal” lighting for my head.
The photo above shows the effect off a higher current changing the bright sparks into a flaming arc. I should add that the whole sensation is a bit strange. The ionic wind and charge accumulation on my hair means I can feel exactly where the electrode is.
The photo above shows an ‘electric kris’. The kris is an Indonesian curved dagger.

Solid State Variac
A variac is a variable transformer used to supply adjustable power for many projects and is invaluable. They are also expensive as they are large and heavy. Here, I explore the solid state option which may be preferable in some situations.
