My Tesla Coil.

Thank you Ray


There's nothing special about that freq., it was just what I had calculated originally
But it turns out my equation was for a monofilar coil of the same length.
So my actual frequency will be different.


I'll probably end up scoping the coil with a signal generator to find the SRF
Tesla gave us the math, I remember reading it but I'm not up to searching
through all the patents and papers again.


so, with the spark gap tank circuit you are basically using pulsed A/C?
radiation really isn't my main concern, this coil should be in the ultrasonic range.
besides a spark in open air
radiates all types of light, sound, xrays


I am kind of curious the difference though,
as many of the plug and play coils you see are using logic timers or a transistor switch circuit.
I haven't really looked into what the circuits are doing. I assumed they just were a/c at the SRF.
V/I designed for the desired output. But I could be wrong. They may be pulsing it similarly.

Here she is
Took about 7 hours of hand winding each turn
total wire length: 2000 ft (1000/1000 bifilar)
Coil height: 30 inches
Coil diameter: 3.5 inches
Total # of turns: 2000 (1000/1000 bifilar)

Choosing the Toroid materials has been the most difficult part so far....
(admittedly I have yet to build the driver)

Engineering the coils was just some boring math
Coiling it was a B.....


But there are so many options for a Toroid
And none of them are what I want....


So.... of the options, I chose to go with the AC flex-duct
As it has great success


Going back over Tesla's mandates,
I have gone with a 4" flex tube, extended to a 10,5" Toroid.


I'll mount it later tonight (once I engineer a mount)
and upload a photo


My goal is to build a batter operated driver for this thing
So it's completely portable.


Tesla Coil car alarm? Fun day at the park? Demonstration piece?
