This is the second and largest Tesla Coil I have built. I should definitely mention all my friends who have also helped in the construction of this coil (and Quantum One): Craig Weirich, Chris Crumbliss, Joe Miller, Garrick Daft, and myself (Tristan Stewart).
I
now have video clips of the coil running
| These were shot in my small apartment at the time, with only the AC outlet ground. I connected a non-working floor lamp to ground for a distance reference. This was before I got the GE Potential Transformer; instead, I was using a bank of 5 NST's for a total of 12kV and 240mA. And also used a 120BPS SRSG. | |

| First run, about 3/4 power on the variac, lamp placed 40" away from toroid. | Second run, near full power, lamp is 48" away. |

more new pictures I dug up

| Here I am sitting by the coil (double exposure). | An outdoor run that didn't perform as well, but still made decent arcs when the ground rod was 3' away. | A 1/2 power run with a pop can placed on top. I thought the name on the can was appropriate. |
The original pictures of the coil:
I apologize, these pictures aren't that large. I will have to re-scan them in, as I originally made this website years ago before high speed internet was common.
Well,
here it is!
I
am sitting by the coil so you can see approximately how big the coil really
is.
It's time for some sparks!
Here is a few shots of the coil
ready to run in the garage.
A good view of Quantum One.

Primary coil.
Coil Specification:
Primary Components:
-14400V Potential Transformer
(rated at 1500VA)
-safety gap
-.04uF 40kV Pulse Capacitor
-20 turn primary coil, #8AWG,
close-wound, tapped at 16 turns, flat spiral
-rotary spark gap
Secondary Components:
-6"PVC coil form, #28AWG enameled
wire, 24" winding length, polyurethane coated
-two ground rod(3' long each) buried and
connected with #6AWG
-toroid: a 8"x21" steel stovepipe
toroid with two 4" diameter aluminum ducts wrapped around the outside.
Original Configuration For the video clips at the top of the page there were a few differences:
-using 5 NST's for a total of 12kV / 240mA
-using a Synchronous Rotary spark gap w/ 1/8" tungsten electrodes, 120BPS
-using a 6" flexible aluminum toroid
