Pictures from builders using Nut's & Volts
Halloween article.

Taking good pictures of sparks is difficult,
but you guys have done it again!!!!
The classic "bolt" of electricity when the
coil is run with a neon sign transformer. The bolt you see is usually
thick and quite loud.
Note that despite the increased power from
the NST (as opposed to the smaller input transformers mentioned in the
article) the spark length did not increase with this coil exponentially.
However, as you can see, the character and energy of this spark is a whole
new animal!
I lost the address of the talented builder
who constructed this coil. I'll post it as soon as I hear from him
again.
This coil was built by Robert
C. Powell (rcpowell@swbell.net). As you can see, the PVC form was
extended, and the coil was built to be cleverly concealed beneath a table.
As "Trick or Treaters" approached, the coil was fired arcing sparks to
items on the desk and to the candy!
I'm told that the high frequency "skin effect"
was also used to the delight of many "Trick or Treaters" as well.
:-)
This coil was built using the
Nut's & Volts article as a starting point, however using the software
and ingenuity builder Terrill Spotanski (Spotanski.Terrill@tci.com)
added a torroid and other touches to the design. Look at those BEAUTIFUL
streamers in the close up shot! Great photo Terrill.
