This is a multilayer Tesla Coil. It is a still uncompleted unusual Tesla project. It is a spark gap driven air cored resonant transformer, i.e. Tesla coil.

Tesla in the Moonlight
Ain’t this just like “the cow jumps over the moon“? A simple shot of Tesla coil sparks framing the full moon in the background.

Exploding Easter Bunny
This is the high voltage vaporisation of an Easter Bunny’s aluminium wrapper. If you are sqeamish, look away now. The Easter bunny meets 50,000 A might be a suitable title.

Ball Lightning
Ball lightning is the collective name given to a luminous ball that has been reported anecdotally often in association with natural lightning.

Briefcase Tesla Coil
Tesla coil in a briefcase. This is my latest easily portable mini coil which gives 2-3 inch sparks. These are great fun and are generally safe due to the low power.

Xmas 2007
Merry Christmas! This is a single photo from a Nikon D70s digital camera and is a 91 second exposure of a real functioning Tesla coil and is the result of perhaps 50 hours of preparation. It is cropped but otherwise completely untouched. It is not, repeat not, photoshopped. It does however achieve the result using special effects which I will explain.

My First Tesla Coil Discovery
My first TC was ‘discovered’ while running a spark spectroscopy project (above) in high school 40 years ago. This used about 10 kV from multivibrator excited dual ignition coils through 10 turns of an air cored radio coil to quench it. The other end of the 130 turn coil developed a corona visible in the dark spectroscopy room. It was a truly amazing sight.

My First Tesla Coil
My first Tesla coil using a neon sign transformer with a ferrite cored secondary giving 2 inch sparks. I developed this idea with an old transformer from a dumpster which in retrospect was an old unpotted NST (neon sign transformer). I used a single static gap with a 12 inch ferrite cored coil of 11 primary and 100 turns secondary giving 2 inch sparks with 26 small ceramic capacitors with 2 strings of 13 x 10 nF at 2.5 kV each. It ran nicely for about 20 years! This photo is a mock up with most of the original parts.
I developed this from my first “Tesla coil” discovery while doing a spark spectroscopy project. Years after I made it I heard that Tesla had beaten me to that discovery by quite a few years! This photo is a mock up with most of the original parts.
It now has new life as a Jacob’s ladder.

Nitrogen Laser 3
I have made a third much smaller nitrogen laser but with higher power and it can be fired a lot faster.
