Hi MX100, Yes I have build a few, I've built small 12 volt mosfet switched continuous wave transformers, receivers as well, and I have a spark gap TC as well, it will be getting a small make over soon, increased power and lower frequency.

Here's a few clips. Keep in mind the Spark gap coil is a three coil design and has only 38 turns on the secondary and 180 turns on the extra, about, I don't remember exactly,
there is only one primary turn, two pipes in parallel, and this is a high frequency spark gap coil, most spark gap coils are much lower frequency, mine is 750 Khz.. This coil is tuned to about light speed "apparent" propagation.  Transformation ratio alone with 6000 volts input and considering the 1:220 transformation rate should get me 1.3 million volts potentially, and that is without resonant effects considered, but it leaks off well before that happens. The secondary and extra coils are made from 1 mm magnet wire so the entire oscillating section of the coil has only a few ohms resistance, the coil is medium to high "Q" in my opinion.

I am much less technical than TK is, I rely a lot on feel, but math is very important, if i could do the math better I could get better results with less effort.

Spark gap Morse transmitter. That message was received up at the house clearly "breaking" into the Am radio broadcast on a regular portable radio receiver.
http://www.youtube.com/watch?v=oeDaA7zhD4w

I had a case where a friend reported that my older 12 volt transformer was interfering with his car radio from about 5 kilometers out. It was only using about 6 watts of power but out of tune, the continuous wave not tuned in at that particular time, different experiment. It affected his radio right up to my door and stopped when I turned off the transformer.

With a clean continuous sine wave only one frequency is affected. Noisy wave forms affect a lot of stuff. Any switch mode stuff does a similar thing, HF transients I think.

So we can imagine what a high power spark gap coil does to the radios. hehehehe


Solid state low voltage. I have quite a few video's investigating the continuous wave transmission effects.

Basically I have done several hundred specific informal experiments with resonance in a few applications.

Looking awesome !

Have you ever heard/readed about putting voltage in coil, which speeds up the hertz.
When you bring down the hertz you get more volt out then in ?

1.) Also I wondered, as there is no clear answer around, when you transmit and receive energy with the Tesla Coil (hot current) do you receive hot current, or mixed current or cold current ?

2.) Did you ever tried/thought converting 1 coil with Tesla's arial system (static energy) ?
3.) Perhaps once had a occurrence of a 'ball of lighting' going trough the room for X second(s) ?

4.) Are you perhaps familiar with plasmoid which can be created with very high voltage's ?

5.) Forum wise question, there isn't a function to see which topics are started by a user unlike more common forums ?
Is it disabled or module not added because its SMF ?

I personally haven't but I read a lot of it.

Sincerely

Honestly I am unable to answer most of those questions, I don't subscribe  to "hot" and "cold" current, there is conduction current (like through and/or around wires)  and there is
displacement current like through the plates of a capacitor.

I do get more voltage from a receiver coil when doing transmissions yes, but never more power and never more energy. I can use a Tesla coil to receive environmental energy for free yes.

I can use one to listen to the radio without any local power source and I can use one like a detector connected to the ground with the output coil scoped and see the disturbances created by an approaching storm or other sources.

For me a Tesla coil is a piece of experimental equipment. They can be used for many things.

I think Utkin is full of it and Don Smith was a fake I also think Tariel is a faker.

A Tesla transformer can only transform or utilize energy that already exists. I don't discount that maybe a transformer could maybe collect environmental energy during a transmission and increase the efficiency, maybe from a cell phone tower, radio transmission source or any other source that is compatible. I am yet to see any proof of over 100% efficiency. But I do see a lot of misunderstandings and miss quotes of Tesla, as well as people making claims for Tesla that he did not make, out of context quoting is rampant.

My advice is spend a year or two studying resonance and build some coils, operate them and you will see for yourself, it's not something that can be explained in a post.

Start with the basics, build two identical air core resonant transformers and tune them to each other and then go from there. Beat frequencies can be created which is the difference between the frequency of two coupled transformers, a "beat" frequency wave form can have a higher amplitude than either of the parent waves but it is simply an addition kind of thing.

I guess my point is there is not one person who will show openly a significant amount more energy out than is provided by the operator, video's cannot be believed unless the device is independently verified.

I can get free energy from a Tesla transformer (resonant air core transformer) but only what is around and able to be utilized.

I going for a NST this week, and I wonder since most NST are simply solid state and thus not adjustable.

1.) If I put a control unit INFRONT of the NST (to adjust the current that goes towards the NST) will I be able to tune my NST voltage's ? I think yes, but want to ask for sure.

2.) Also you stated you use magnet wire, but magnet wire is same as normal wire you get out of a 220V cable instead of the thick plastic it comes with a very thin layer insulation right ?

3.) In a Tesla coil, u can't have enough capacitors ? Or you need to calculate it as it may overcharge ?

4.) Have you, or anyone here, noticed any difference between a normal winded secondary coil, and a bifilar secondary coil ?
If so what are the differences ?

5.) I never readed anything really about tesla pancake coils in Tesla Coils, why is that ? (Yes I assume that they are incompitable of not effective for what they needed for, but again why ?).

6.) What type of coil you used ? Pvc or acrylic ?

Also TinselKoala sended you a PM about a yt vid of you, could you please respond or make you're findings public here ?

Sincerely all.

So, I am building a (huge) Tesla coil


I have calculated the desired frequency to be ~492kHz
(491.78kHz)


does anyone know of a simple oscillator that can be tuned to this?


Also, is a spark gap “necessary”?
Or is this simply remnants of an old-world convenience?
I.e.: an modern a/c oscillator by itself could run the primary

Ok, I answered the spark gap question


No, we don’t need a spark gap.
That’s just an old way of controlling frequency
There are many Tesla coils that operate straight
from a signal generator.


So, next issue:
Every reference I have found shows coils being wound with
only ONE wire!!!!!!  I don’t understand this.
Tesla Clearly wrote about why we should construct this device
using Bifilar coils.... for both primary AND secondary!!
So, this is what I am doing.


My next question is:  how to wire it up?
My assumption is to connect the top most wire to the top load
and bring the bottom of that winding back up to the top of the 2nd winding.
(should the return lead be positioned away from the coil?)
There is little reference to people making bifilar secondaries.
Any help here would be great.
Also, since the field is doubled, how does this change the inductance equation?
Which, in turn, changes the SRF of the coil....

Any of you Tesla Coil owners using a Bifilar secondary?






BTW:
If enough people owned Tesla coils, and we standardized some set of frequencies
We can build our own wireless power grid.

;D then take the suppressors out of your vacuum cleaner and see what it does to your tv sound and video then try your radio!  ;D ;D ;D ;D ;D
There are many Tesla coils that operate straight from a signal generator.
that's not a real Tesla coil ass your using the transistor to turn the coil on and off like a sine wave a spark gap or interrupter would pulse it and jam everyone's radio reception in close proximity  :o   ;D ;D

Fun ainit !

(491.78kHz)
What is so special about that frequency?

does anyone know of a simple oscillator that can be tuned to this?
use a crystal and devide it down as close as you can to that frequency ie divide by 2 then use a shift register and knock off bits easy but you will have to use logic a micro will just keep falling over.

Also, is a spark gap “necessary”?
Or is this simply remnants of an old-world convenience?
well if you don't use a spark gap how do you charge a cap and then dump iy across the secondary coil
you could use MOSFETS but they are expensive if you blow them up IGBT#s have losses across them at lovw voltage like bipolar transistors and charge time will change coil frequency and resonance.
I.e.: an modern a/c oscillator by itself could run the primary

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.

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?
