increasing L2 cap
« Reply #425, on June 18th, 2022, 10:02 AM »
In the hope of tuning the resonant frequency down to a subharmic of L4

I changed the c2 tuning cap of L2 from 117nF (which already is big)
to more then 500nF.

and it doesn't tune down. it just stays resonant at around 185kc/s

since the parallel cap of L3 is only 6 or 7 nF the difference between primary L2 amd secondary L3 is to big.

When L2 and L3 are tuned by more equal size caps they both influence the resonant frequency.

I tried making The c2 (L2 primary) cap smaller, but naturally the frequency then only becomes higher, and thats not what I need.

I also loaded L3 again (instead of L4) which showed a bright lamp, I haven't calculated the power, but did write down the input vs output.

It slightly detuned the whole system, so that's another task.

but first I need to create a higher voltage load so the resonance can do its work better.
I plan to series connect a couple of 230V Halogen bulbs.

Also I want to use a different bulb to burn away the impulse energy to make clear how much energy is in there.

unifilar l1 l4
« Reply #426, on June 18th, 2022, 11:01 AM »
impulse is to slow, nit giving enough current amplification in the secondary.

only yhe primary and secondary should be bifilar.

the L1 and L4 should be unifilar.
a quicker extra coil, for a quicker impulse that is higher in voltage.

4 equal coils,
2 bifilar, L2 and L3
2 unifilar by paralleling their windings (instead of series)

Also the 15 mm is to close. the frequency is to high.
coupling also works fine at 25mm, which I tested way back.

coils with thinner wire. for more windings and
lower res frequency.

the caps are working good up to 100kc/s

I made an impulse burner for comparing

I reduced the outside windings of L4 to get it faster.
I removed all the caps parallel to L1.

to my surprise I saw L4 as a pure sine wave without ripple, so I added more capacity parallel to L3 to tune down,
and then the ripple appeared on L4.
I measured it to around 400nS for a half wave.
which is almost exactly the speed of the impulse of the L1 coil. no caps needed!
perfectly tuned by intuition. now how do you teach that to someone on YouTube...
its an Art.

Now I still need to show the displacement current amplification of L3 current.

To do this I need a more loose coupling between L2 and L3. so only the displacement current is kicking L3.
and not the magnetic current from L2

the impulse being much faster now is easily 3.5kV again (at lower frequencies).

placing the coils further appart will also lower the frequency again which is good.

going to. make new coils. as the current ones are in epoxy.

power from ground
« Reply #430, on June 24th, 2022, 05:40 AM »Last edited on June 27th, 2022, 02:49 AM
So if power comes from the ground, and I need the L3 secondary to be grounded...

I tested before to see If I could get a DC charge in the cap, and that worked, but L3 wasn't grounded half of the time due to the diode/cap.

So... I use 2 diodes and 2 caps, to create DC, placed between ouside rim of L3 and earth ground

edit:
as a variation, the diodes can also be placed on the ground side of the caps.

and I keep seeing the l4 extra coil placed on top of the L3 secondary. instead I use pancakes that are coupled.

I see the pumping action comes from the extra coil which has voltage and current in phase.

so L4 produces a alternating ring torroid/vortex ring.

normally these rings want to move through the ambient medium (effortlessly as longitudinal motion).

but the ring is now fixated around L4, so now instead of the ring vortex, the ambient medium is being moved around the the coil, and this is the pumping action. this is why the aerth responds. the ringvortex sucks in aether currents out of the earth and pushes Aether currents back into the earth.

this works together with the displacement currents of the L2 L3 coil cap which power the ring vortex.

Since the coupling of L1 and L2 seriously decreases the input power, and the coupling of L2 and L3 is loose, the impulse that drives the system is produced much cheaper than the aether current flow that results from the resonant oscillations.

first test with rectifying ground was not effective. I used a load. and wonder if I should first let the voltage build up inside the caps, before loading it.

tuning L2
« Reply #432, on July 4th, 2022, 07:57 AM »Last edited on July 5th, 2022, 03:00 PM
L1 by itself produces impulses, and very efficiently, as the impulse energy is captured into the cap at the drain again.

So by itself it is a very good primary. it produces current and impulses. perfect!

So why then use L2?

L2 increases the power draw.

L2 is made series resonant, and recieves the impulse from L1. but with being series resonant, it can also produces massive currents.

So that makes sense.
high currents with high voltage impulses.

until now I thought, I should bring the current down in L2, so that the loose coupled secondary L3 would not drag down L2 from the load, by magnetic induction.

something to consider...

So the question becomes,

should L2 have high currents combined with the HV impulses?

edit
L2 is needed to ger LMD resonant mode in L3.
large capacity on L2 gives best displacement current from impulse.

reversed L4 extra coil
« Reply #433, on July 6th, 2022, 03:05 PM »
I flipped L4 over (close coupled to L3 secondary)
And reverse connected it, inside of L3 to inside of L4, ouside rim nnot connected of L4 extra coil.

Tuned L3 for max current again, needed 8nF parallel for that.

Now current in L4 is higher than in L3, but ground current is lower. 1.8A
I needed to temper my power supply down, as the L3 caps started sparking over (probably at the switches).

Still I had around 9 A in L3 and L4

Doesn't make sense, I see nno differnece, I will flip L4 back againn, and reconect it.

Tuning L3 for max current still is amazing to see.  I reduce the capacity, frequency goes up. And the currennt goes up. So not what is expected. But I understand this is current amplification, by the displacement current of L2 impulse.

Made a new switch today with my new PCB's. still a few mistekas that need correcting, but the board is very quick. 330ns impulses, that was 390 ns before with the same coils

L3 phase shift
« Reply #434, on July 6th, 2022, 04:18 PM »
When L3 cap is to big, the impulse is post (right) of V max L3.
when to small it is pre left.

when given the right cap (around 17nf) the impulse is on Vmax L3. and thats where I want it.

but when I then measure current on L2 (impulsed primary) it doesn't look as a sinewave at all. the cap is very big 117nF or something like that.

So L2 does need tuning.

I measured ground current, almost zero.

impulse is fast and high voltage. L4 profuces perfect sine, with slight ripples.

very hard to see if impulse is to fast (to slow doesnot give l4 ripple).

also played with distance. current amplification is less when to far away. still vague

Re: Radiant coil capacitor
« Reply #435, on July 8th, 2022, 05:49 AM »
Ok I tuned L3 for max current with only 4nF parallel.
then I tuned L2 vor max current, which behaves  strange.

the L2 current is sort of "dipped" and only when I detune the becomes high again.

I recorded it for review.

I now have the distance between L2 L3 set to R, the inner hole radius which is big.
that's also why the frequency is relatively low from loose coupling around 154kc/s

L2 has 32.8nF im series
L3 4nF parallel

I need to change the distance again, and retune and see what happens. compare it.

tried loading L3 again, and now its not even nlightinng up the lamp, only showing 50mA DC from rectified L3.
which does make sense as the parallel capacity on L3 is now much smaller, it should also deliver less  current/power

So tuning L3 must be done while loaded? and then look again for max current? oh man... I feel lost again.

But it looked so good without load. The ripple on L2 is completely gone.

definitly not there yet...

back to the old coils
« Reply #437, on July 10th, 2022, 02:58 AM »
tuning the impulse to the extra coil is hard.
I had 4 new equal size coils, but I could not see the ripple on L4 clearly anymore.

without proper tuning there is no real earth  pumping action.
Altough I have my doubts about that also.
my current probe was also registring high currents outside of the circuit (in mid air)

I guess the circulating displacement currents are picked up by the current probe. so maybe it needs extra shielding with ground.
I even consider using copper tape.

My newer better current probe (500kc/s liniear up to 100kc/s) was overheating, so I returned it for repair. apparently Pintek has an older and newer version PCB, so I hope to get an upgrade.

I picked up my old coils again, in epoxy, and connected it. before I had good results without L2 being tuned, so now I need to see again if it works. First I need to see if the L1 impulse and L4 are tunable again.

then I wonder if a single diode rectification from the L3 L4 series connection might work, with the other side of the dc cap to ground.

ground current can be measured away from the system to be sure it is real

My current probe  needs shielding...
96A pp

it was placed on top of the coils.
in green with 20A/div the current measured

I wonder if this normal behavior for a current probe.

maybe it is due to the displacement current being pumped through the coil hole, and the probe?

Extra coil needs inductance not capacitance
« Reply #439, on July 10th, 2022, 11:14 PM »
L4 Extra coil needs inductance not capacitance

so NOT a bifilar coil it has higher charged capacity.

L3 secondary has amplified current, from displacement current of L2 primary impulse.

So L3 has high current and voltage.
L4 can bring the voltage up (dielectric field movement) by having mostly inductance and less capacitance.

bifilar coils also have mutual inductance between its 2 windings, so a solonoid shaped L4 extra coil combined with the pancake secondary L3 might work best.

but field shaping comes to mind,
so maybe a thinner gauge wire with much more windings in pancake shape.

or... pancake bifilar series connected but not Tesla style, instead series connect both the inside rims or outside rims.
although that also does not have much inductance due to counter rotation of the windings /fields.
it is seen in the kapanadze coils, although they are solenoid not pancake, the trick. is the same.

I now use 0.75mm2 which is as low as I want to go. but I have it tesla bifilar.
best would be equal mass single layer 0.75mm2 with wider outer diameter.

more inductance less capacity.

Tesla also needed more windings as more inductance has more inertia, has more volume of aether captured.

Colorado Springs notes
sept 19 1899

Various arrangements with oscillator and extra coil for most powerful disturbances.
....
diagram 4 seems the best
...
fig 1 only increases pressure(voltage) at end
....
fig 2 and 3 vibrations through the ground are intensified by the extra coil...
in all cases it has been found important to have the 2 systems vibrate in SYNCHRONISM.
...
what is the best length to give the wires?

(fig 4 shows condensor parallel to. secondary)

with both 1/4 wave length the action is not the most intense.
with the extra coil 1/2 wave length and the secondary 1/4, they both cooprrate on the condensor producing on the ball a much greater pressure (voltage).
...
it is found best to make extra coil 3/4 wave length and the secondary 1/4...
thank you Master!

so... odd harmonics, but not even full octaves between L3 and L4 should bring the effect?

and currents running up and down both directions? and since we have 2 kinds of currents, this is possible?

pure octave harmonics keep their end nodes in the same place

no....

hmm I have to start looking at the earth ground as a capacitor plate, and the extra coil inside rim open end as a capacitor plate.

series parallel resonance
« Reply #442, on July 13th, 2022, 01:52 PM »Last edited on July 14th, 2022, 12:42 AM
L3 is parallel resonant with C3
L4 is series resonant with C3
if tuned correctly
L4 then has the same frequency as C3 and thus L3

thats why the frequency of L4 can change to that lower octave.

and with equal sized L3 and L4 coil that is easy as they interact with the same capacitor.

since Parallel resonance wants to pump the capacitor from both ends, it might be that adding series resonance to one side of the cap, the other end of the cap also wants to pump (which is earth ground)

the impulse induced displacement aether current moves into L4?

evostars

no earth ground needed?
« Reply #443, on July 14th, 2022, 03:11 AM »
Tesla also showed the secondary with a two extra coils connected im series at both ends of the secondary.

That could make it possible to work without earth ground

unbalance by extra coil
« Reply #444, on July 14th, 2022, 06:19 AM »
with the parallel resonant secondary L3 and the series resonant extra coil L4 using one and the same capacitor (c3)
the c3 capacitor is disbalanced by L4 and thus is balanced at its other plate, by the earth. which by itself is also a capacitor plate (forming a capacitor with the ionosphere)

So could the energy/power come from a harmonic of this planet capacitor that already is vibrating, using a harmonic?

L4 extra coil definitely needs large inductance to create the disbalanced.

my tests with equal sized coils made that clear.
the test with larger inductance L4 was much higher amplified.

I wonder If I could use 2.5mm2 for L2 L3 again and a 0.75mm2 coil for L4.

Re: Radiant coil capacitor
« Reply #445, on July 15th, 2022, 03:21 AM »
if L4 is series resonant with C3, it still has a loose end, maybe a large capacitor to ground or even grounding it directly might work,
but that is just for quarter wave operation.

open ended It could also work as half wave resonance. with a node in the middle of L4. and both it ends resonating (180 out of phase)

but tesla said 3/4 wave. Whould he have meant, 1/4 for L3 secondary and 2/4 for L4 extra coil, together 3/4?
that makes sense.

So, half wave resonance for L4. twice3

VNA

I have ordered a VNA
vector network analyser.

after seeing the work of adrian Marsh, am-innovations.com
it has become clear it explains and shows much of what I now see.

each coil also has a parallel mode besides its series mode.

with the series parallel resonant secondary and extra coil we should be able to tune both the series and parallel modes, with the single tuning capacitor.
IF the extra coil has the right dimensions.

VNA makes this visible.

Re: Radiant coil capacitor
« Reply #447, on July 23rd, 2022, 08:25 AM »

so from this video, there are parallel modes of high impedance and series modes where the impedance is lowest and phase shifts.

coupling the primary and secondary, shifts the frequency into a lower and upper frequency.

with a balanced mode the power tranfer from primary to secondary is optimal

What I now wonder, is can we join the parallel and series modes, by using the extra coil. I think this should be possible.

a VNA has it's limitations. I for example do not think it will work with series tuning capacitors, only with parallel, so the primary cant be read this way.

but the secondary with extra coil, and parallel tuning capacitor can be measured. this is rather complex as there are multiple resonant modes

made a connecter for the VNA and coil.

I wonder If I could measure series resonance of the primary, by TX connected to outside rim
and inside rim connected to series cap, and then to series ground.

I have to be careful not to exceed the max voltage, if it works differently than expected

series fed, can only work with parallel shunt tuning cap to my understanding.

parallel fed, should work with series cap but... how to test this safely without blowing vna?

VNA was sold out!

I realised I already have the parametric excitation working.

by the impulse on L2 The L3 is amplified in current.

normally the excitation is twice the frequency, but that would demand another impulse on the primary L2 that is positive voltage.
I tried to achieve that with the half bridge, but found out it can't work due to the diodes passing both polarities.

So the magic now is only to tune L4 to L3.
whereby L3 is 1/4 wave length and L4 is 1/2 wave length.

so I should make a new L4 which has more windings, from twice as much wire.

then Tune L1 again so the impulse matches L4
and then again tune L3 for max amplification.

back to rolling coils.
