Building DS Plasma Globe

[h2ocommuter]

OK here is the process proposed by DS for my particular IT.

I will explain it in total.
What I am going to ask of the professional EE's is a direction about how to choose the right description for my cap bank values when ordering these parts.

When using this LC calculator, http://www.whatcircuits.com/lc-resonance-frequency-calculator/ the last sentence is precisely the explanation DS had so many times referred to when using freq's above 20K Hz.
With this calculator insert the L and T and it will give you the C value. These Measurements align exactly with the Nomograph in the electronic tables and formulas he suggested to use for setting the timing of your application.

The circuit diagram is from NT as Don said to use it to finish your device.


Using this link you will read the curious question about changing freq. changed by using a resistor, "in so many words". http://www.kpsec.freeuk.com/components/vres.htm
Rheostat
 
This is the simplest way of using a variable resistor. Two terminals are used: one connected to an end of the track, the other to the moveable wiper. Turning the spindle changes the resistance between the two terminals from zero up to the maximum resistance.
Rheostats are often used to vary current, for example to control the brightness of a lamp or the rate at which a capacitor charges. 

Many difficulties occur when trying to incorporate a resistor into a closed circuit as you all  know. what Don has done is by leaving the spark gap in the circuit the closed circuit will not short itself out. thus allowing the magnetic occurrence to flow in the circuit.

I do not expect any grief just yet. I on the other hand would like some help choosing the in depth criteria for my capacitor bank.  Expert EE's Wanted!

I will be more clear with my findings about the variables as stated by DS. I admit I have not figured it out.
Here are three scenarios I want to try.

# 1. 120 CPS = 60 Hz with It = .1352 H shows a 95 ohm resistor giving us a 13 uF cap.

# 2. L-2 =12.55uH with Globe naturally cycles at 22,525 Hz with a 4 uF cap and a 1.9 ohm resistor.

# 3. Required CPS for 240 Volts = 1.7 MHz using the .01255 uH L-2, a .13 ohm resistor and a .07 uF cap

With these variables inserted into the homograph or the previous calculator will show the three tests I want to measure.  This stated, the resistor is emitted.
The capacitor types is where I am having trouble understanding.
Electrolytic, mica, oil filled , paper, omg there are so many choices. I would be wasting my money if I didn't ask.
I can waste my money on testing but not on stupid ignorance.
I have humbled myself can someone help me choose?

What I have done is using the proposed circuit from DS acquired from NT is, use it for the plasma globe.  Nothing perfect yet. but I have accomplished sending magnetic flux through the IT.
This is preliminary testing; this configuration pumps an unknown DC pulse through the IT. It inductively excites the output side where I have this wired into a circuit breaker box, receptacle, and a normal light bar.  This is all on the test stand.

I have made some observations that may clear some abstract peculiarities up. Although no definitive choice has been made I have chosen to analyze the NT circuit. Here is what I find.

Through many tests; I have concluded that no magnetic readings can be obtained without a spark gap.  As there is more than one type of SG, I have chosen to build both types. (With and without earth grounding). These two SG have micro adjustments so, a myriad of intensities can be obtained. With the earth grounding SG, I use 316 SS because it has nearly no magnetic attraction. I should continue with these advantages. You can vary the gap to where the spark is barely able to jump and this causes less Tesla. Closing the gap will emit more Tesla. Note, The ambient + or - values are not easily readable with my Gauss meter. So at this point I am satisfied with this meter. Furthermore, The freq can be adjusted in the same manner; less didstance faster commute. more distance longer commute.  POW. play on words!
Now the positioning of the SG is pretty important. Being that it is next to the IT. And I should mention that this is an air gap, not a earth grounding SG as pictured. 

As things go , I will hypothesize that using an earth grounding will absorb a certain type of ambient background energy; probably more neg, and the air grounding will absorb the less negative ambient energy.

@h20,

Let me start out by saying that I watched your vid's and I am impressed, keep at it!

Are those resistor plugs? Thought I would ask since that might skew your results if they are.

A few thoughts to share with you...

Why not use a few pieces of iron bar (round stock) for the electrodes instead? grab some 1/4" or 3/16" stuff from home depot.

Have you thought about adding another coil into the design? the DS design shows a centertapped coil (transformer) just an observation. Plenty of variable to try I am sure. I am trying the replication of DS's design using a tesla coil instead of a NST. I will see how that goes.

Good luck

@ Starcruser,

I don't feel the need to deviate much from the written directions for the plasma globe.
What I am validating are the initiations DS has put forth in his literature.
NOI, no offence intended, The centertap aircore coil or the centertap neon sign transformer are for other various devices.
The only drawing, video or lit. about a centertapped transformer is the suitcase output transformer. "as far as I can find". I have turned my IT around so I can pump it through the centertap and see if the respective more neg. and less neg. will collect from the respective SG's
The plugs are not resistor plugs, I chose plugs for mounting ease, and longevity. these off the shelf parts, and are virtually indestructible with the pressure I am driving them with. I think.
If I have major problems I will fab what you are suggesting.

I have wound two other coils that seem to work less effective but when I get a circuit working to its optimal I change out the coils to see if another will outperform the one I am using. I have stacked them up working at the same time and the results are there too. So realistically there is plenty of room to find more energy if that is desired.
I can validate 1/2 of the output in Tesla's' DS insisted were emanating from the globe and my meter is hammered. So I am sure this globe will put out 400 mG. Lets remember that equates to 40,000 RMS.
My IT will only accommodate 12,000 RMS max. so I need to hold the ponies back to a small 30 % of the overall possible.

What I am doing again is validating what DS has proposed, are the laws of our universe. Physical unequivocal absolute laws.
This will be the objective if you want to reproduce any of these devices. IMHO.

We not only must find the magnetic resonance but be able to manipulate it at will.

(Any spark gap will build massive !!!! magnetic eminence. This magnetic value is pulsed through the IT and there it is, the pulsing of that magnetic value through the IT in the proper dimensions is all we need. to power the system. )
My conjecture and understanding from what DS has proposed we do.
