Powering a Oudin/Tesla Coil using
an X-Ray Transformer, Part II
Do not attempt experiments on this
page, it is extremely dangerous to casually experiment with voltages of
The purpose of this page was simply to prove that it can be done.
Last week I did an interesting experiment with a Pancake Coil, X-Ray
Transformer, and .006 mfd cap.
This week I am doing similar experiments, but at the extreme limit of
things: .001 mfd capacity.
This is similar to two small Leyden Jars, and the experiments replicate
those done a century ago with
6" induction coils / Leyden Jars for powering small high
frequency frequency apparatus.
Two doorknob caps (.002 mfd) in series. 4 series tungsten spark
gap (set from 1/2" - 1")
The gap mounts in holes on top of this X-Ray transformer. They are
9" between centers. This puts the spark gap in parallel
with the transformer and the two caps in series with the Tesla Coil
Having such a small cap size really limits the ability to make an
efficient coil, but this is just a test to see what happens...
First test is 286 turn Tesla/Oudin Coil. P:S turns ratio is approx
24:1. Resonant frequency 1130 kHz
Next experiment is done with Pancake Coil placed approx 6"
above a flat ribbon primary of 15 turns.
Turns ratio is approx 12:1
Resonant frequency around 915 kHz.
