Nice link.
By the way, i proceed without matching the NST to my main LC circuit.

I plan at utilizing one of Tesla's suggested circuits for great undiminnishing resonance. (see below)

The NST will be rectified and feeding the C1 cap for firing at a rate 500 times per sec via the spark gap (say) while the large Cp will resonate freeley (whether the spark gap fires or not) with Lp.

I Choose this because the resonace is quite SHARP, according Tesla saying. By making a huge L1 (0-300uH) i will have extensive tuning capabilities.
My L1 is a bucket 10''+ in diameter with 50 turns of tinned copper 1.5mm wire.

Which book is that from? Interestingly enough I was working on a circuit similar to that last night without the spark gap and lower L . It seems to display some parametric qualities and with the right combinations of L and C can really accumulate high amperage in the tank.

Its Tesla's Colorado Springs notes...

Actually no parametric resonance in play here... only quite large Q and enormous amperages (as far Q permits). According Tesla's testimony, the jars comprising the Lp part broke down frequently due to heavy loading.

I suggest you read the whole book. It a breath of fresh air...

...

Down to that circuit, the L1 in my case will be 100-300 uH and C1 around 8-20 nF. The Cp will be 200-500 nF and Lp 4-5uH.
From the setup readily is seen that when the spark-gap fires, the LpCp is seen as a short cut and does not affects much the L1C1 part much (if at all).
By regulating the L1 here, we can match the L1C1 and LpCp to have some resonance frequencies..

Thus we can ping the LC part with a voltage that defined by the spark-gap and have as much current as the Q of the tank LpCp permits.. Perhaps kilovolts range at tens amps is quite feasible!

Thanks for the book lead, I ordered a copy of it and should have it by next wednesday. I've been working with a 2000 page book with all tesla's lectures and patents in it, it's an old one with a 50's copyright, I've barely scratched the surface with my experiments so far. Still learning....

I will be excused to deviate a little from Don resonance devices and discuss about Tesla coils functionality.

From my reading Colorado notes so far, it becomes clear and many times stated that the coils were destined to be reciprocating electric current pumps from ground-to-toroid and vice versa.

Tesla's nightmere was the distributed capacitance of the resonating inductor as this dissapears most current movement inside the coil and not to its terminal locations, i.e. toroid to ground.

I was puzzled a bit. What does he meant current from toroid to ground. I thought that tesla coils since resonantors and since producing stationary waves, at bottom a maximum current occurs whereas it is a voltage anitnode. And opposite. At toroid almost no current should flow at all but voltage should be maximum...

Question: if that was the case, then how we can justify the fact that the toroid capacitance (one plate capacitor atcually) is charged if not current?
Obviously there is a current...

It is becoming obvious that the stationary wave is about voltage and not current. Current should be uniform (if not distributed capacitance existed) so at top as in bottom of the coil.

I explain. Imagine you have two caps. On the one side of the TC is the one-plate cap hence toroid or sphere of e.g 50pf capacitance and at the bottom of the TC is shunt connected a bigger cap say 500nf of low voltage...

Let the coil resonate... the bottom cap will be seen as a short and would not impede coil's function. By applying standard cap's maths, you will see that more or less if distributed capacitance was not in play that the amount of charge contained in both caps should be the same. (hence amps in and out)

The one of 50pf will be charged at 500Kv and the other at 50 volt. But despite energies, charges should be the same... some 25 u-Coulomb. Supposing we have a resonance frequency of 100 Khz, that means the caps are filled twiced per oscillation, then we get a number of 5 Coulombs oscillation per sec or 5 amps.. (more or less)

....

Bottom line, i think the above point is quite firm, and amperage is irrelevant from stationary voltage (at resonators) and is commonly depended by ohmic resistance of the oscillator, etc...

Nothing magicall actually

[h2ocommuter]

Capacitor choises?

h20,

Hey man! those are of DC type propably.. Everyone must give carefyle note on note the fact that the capacitor needed for a high Q tank circuit must possess certain properties.

namely to be able to work at intended RF (50-200 Khz) frequencies with minimum heating, possessing good Dv/Dt characteristic, etc.

those mentioned (32uf, at 5Kv) are NOT suited for LC tank circuit. Actually there are only for storing energy and used in pulsed circuits.

...

The only way to make my own of the required quality and capacitance is to make a MMC bank like tesla coils.

OMG thank both of you for getting me pointed in this direction.
for some reason I did not see the continued thread posts.This topic still leaves me a bit in the lurch, but I will try to figure the AC/DC capacitor thing out.

I started another thread @ OU. Not that I am bugging out of here, I simply wanted to find a place where I could post findings that were concentrating arround the plasm globe research only. Building DS Plasma Globe


I have posted a few videos showing my progress, the latest is about capacitor charging times and how my circuit is behaving. I am searching for a configuration that will be closed including the IT where I do not need to manually discharge the capacitors to make it pulse.

I have posted other videos showing the dischartge Amperage. I have blown the ammeter so further testing will continue on this subject asap.

HF currents experiments

I was experimenting today with my re-constructed Solid-state Tesla coil like, or "Kacher" version 2.0

I wanted to make some measurments concerning my newly arrived HV HF diodes purchased from e-bay. Diodes tested and found "OK" working at 400-600 Khz.

Some interesting observations were made and some Myths busted. My observations are that my Kacher lights its lamps by the use of ground via capacitative coupling, hence it required ground for the oscillation of currents.

By using an induction coil at the bottom of it and fasten a lamp, no particular lighting I observed. from estimations, the current of my Kacher, is 0.2-0.3 amps at its base (stronger) of relative small voltage.

Battery charging was tried via the diodes and worked, but diodes (10 KV 1amp) tend to overheat despite the fact that little curent charges the battery...

The Myth busted was regarding the "cold electricity properties and in water lighted bulbs". I must say that even though relatively small voltage exists at bottom of my kacher, it bites... so no absolutely cold. Anyway, i conneced an halogen lamp to L1 and the other point to a ground and submerse it to water
.
The bulb continue to light normally, (or slightly diminished) and was NOT shortcircuited by tap water's conductivity. My fingers were also in the water quite safely..

This confirms and demistifies Karl Paulsness hairpin or even Ed Gray demonstartions. HF currents are not like the LF ones. It is not radiant energy. Its just currents of high frequency.

You should have connect Colorado Notes with Tesla interview Nikola Tesla On His Work With Alternating Currents -- Chapter IV

Does someone bought complete book "Tesla presents series" ? I would love to read it yet it costs too much (with shipping costs overseas)

[boguslaw]

"This [Fig. 36] is a form of break which I developed in working with alternators. I recognized that it was of tremendous advantage to break at the peak of the wave. If I used just an ordinary break, it would make and break the current at low as well as high points of the wave. Of this apparatus I had two forms; one in which I drove the break right from the shaft of the dynamo and the other in which I drove it with an isochronous motor. "

Oh,silly me...you are not listening.... why am I wasting my time ?

[baroutologos]

I listen...
Dear Bogus theorizer! tesla as explains in his patent 568.180 and contrary to many contemporary teachings, the breaking of the CURRENT was made at the peak of the CURRENT wave and not closing the circuit at the peak of the EMF.

thus, the stored inductor's energy of the transformer/alternator was captured as a high EMF / current spike by the capacitors (like discharging a coil in a cap).

This way was an useful one for stepping up alternator's voltage.

don smiths circuit

Hi all, regarding Don Smiths circuit - neon transformer to two diodes and then into L1/cap. circuit.
I followed the circuit from Patrick Kellys site Chapter 3 pages 39 to 48.
There is no spark gap in the main circuit as suggested by some contributers that one should use here.
The only spark gaps are supposedly for over-voltage protection to ground.
Has Patrick mis-presented the circuit in error do you think?
My L1 coil checks out at 7.8 microhenrys.
This is extremely small.
Total impedence of coil and resonant cap. for 35 kcs is only 2.5 ohms !!
Is anyone else getting a voltage build up on this near short-circuit coil/cap.?
If so, how did you accomplish this?
What is your voltage here?
mlurye - you reckon 200 kcs is the resonant frequency.
Don says he uses 35.2 kcs.
How do you reconcile these two totally diferent frequencies??

Never trust any of Smith´s verbal component value statements.
He gets the voltage of the NSTs wrong in different speeches and also he sais that his primary side caps are 10 or even 15 kv caps , when you can clearly see that there is 4000 V DC written on them.

35 kcs is most likely the operating frequency of the NST. I recall him saying that in one of his lectures and this value sounds reasonable for such an NST.

As for the the (resonant) frequency in all his lectures and books together he sometimes states Mega (!) Hertz or 200.000 Hz, where 200.000 Hz seems more likely.

[baroutologos]

Wehave an enigma here.

Don SMith is a dotard old man! His theories are highly incosistent with his sayings. Even the part specs are read wrong from time to time. Actually Don, apart from the mysterious and suspicious suitcase presented at the Tesla conference (1992?) never has shown any device at work.

The thing becomes a little more complex, when you have the clear presentation of Tariel Kapanadze, showing an excess energy from the earth using Tesla methods (as DOn) and according to Partick Kelly, Kapanadze gives attributes to Don Smith!
Either they have both something (our bet) or nothing and fool us around.

We bet in something, and since they would not tell, Tesla study is a must coupled with experiements in that direction.

This is IMO the hard, yet most "efficient" road to go. This should be a collective effort from skilled experimenters and researcher and result should be shared also.

Yes, the thick coil and large caps, seti in parallel seem like a dead short. But still they are a LC. Find their resonant frequency and tapped them until best results are obtained. You should expect with fine high Dv/Dt, loss Diss. Fct. caps that the voltage can (?) rise to KV value and amps to tens. The Q factor on this circuit rests only in the Low Resistance and frequency, since Inductance is minimum.

Actually they are two general "ways" for achieving resonance at given frequency. High inductance, small capacitance and vice versa. The high capacitance, small inductuance is the lossy type due to heavy amperage flowing the circuit. Still it is the model prefered by the "notorious" DOn Smith and as it seems from Tariel Kapanadze.

Intensive experimenting is a must
