Thanks for the tips Lynx and Matt.
I bought a Creality CR-10 mini 3dprinter. not realy mini, just a bit smaller. 30x22x30 cm build space more then enough...

pretty special, 55W 230V halogen light starts to light up.

L1 is removed from the stack, onl;y L2 and L3 are stacked (coupled) non reversed.

C4=54nF C6 (over L3) is 10nF
Without the lamp (load) over L3, F=114.20  0.72A  28.4Vdc (lowered for C5, it got hot from to high voltage). L3 shows 550Vpp (very high)  this is shown in NEWFILE184
700V discharge in L2!!!
L3= 570Vpp
l2 = 170Vpp without discharge, only sine


newfile 185 is the same setup, but with the lamp connected parallel over L3. 0.74A 28.4Vdc F=109.2kHz
L3=325Vpp (rather high!!!! with a load!!)
Rather remarkable, because normaly with resonance, the lamp wont burn at all, and the sine over L3 would be a flat line.

Must be some current produced here.
Hi evostars

Very nice experiments and promising results really !!

What is your best result till now ? I refer to monopolar (unipolar) nanopulse amplitude of votage and current in collector L3 coil ?

Great Tesla told us about huge power he had released from disruptive capacitor/s discharge, but never told us the real role of his pancake bifilar coils except they are excellent voltage boosters due to their intrisic capacitive nature. I think we should correct our view points in sense he had thought about coil-capacitors or precise pancake-capacitors in form of bifilar windings and their disruptive discharge/s.

In my oppinion radiant effect is a result of microscopic quantum resonance - Rimily Avramenko Fedorovitch term. Further i think there has a place of unknown Aetheric compression/decopresion process in nano (pico) scale time domain. It is well known fact that Archimedean spirals very similar to Tesla pancake coils, are used for compressing gases, why not Tesla pancakes for electro-magnetic compression/decompression of Aether.

Something like this - interaction of two counter winding coils


One remark about coil's mass equivalency - Tesla's term. This give us further implication about virtual (floating) ground mass equivalency (similar number of sub-atomic sub-etheric) particles play role in radiant transition effect. So if mass of both double coupled - double  interacted coils should be the same, it show us same rule should worth for virtual ground which twist around continuous polarity change.

Second remark is resonant frequency ratio between L3/L2 coils took place around phi golden ratio. fr(L3)/fr(L2)= 1.618. Knowning that  Archimedean spirals were based on Golden Phi Ratio, there is no surprise that disruptive resonant effect was ruled by same golden section law.

Best regards and good luck in newest experiments

I checked source and gate voltages to see if the mosfet switches properly. It does. +10V when on, negative some volts when off. nothing wrong here.

Tried several frequencies of series resonace of L2 again, with a 24,4 ohm resistor parallel over L3.
I noticed the increased resistance (before it wa 4.1 ohm) did increase the frequency of L2, when using the same value of C4.
This can be explained, by a larger part of the voltage of L3 is tranformed into current by the larger resistance.
The 24 ohm resistor is 3x  8 ohm resistors in series. one of them is only 5W rated, and gets hot (!) So current is produced.

I tried tuning in the frequency with max current. It varied between 0.6 and 0.8 V measured over the current probe.
This time i didnt ground L3 as it produced a more clear undistorted voltage.

the max of 0.8 volt was somewhere between 131 and 149 kHz This is the same result as I noticed before, with the 4 ohm resistor.  Since I dont have a decent current probe. I guess I will proceed in trying to get L3 resonant at 149kHz, by adding parallel capacitance.

I wrote every measurement down, but since its so crude, (I really need a decent current probe) I will not take time to write it all down here.

luckily, now the resistor is in place, the frequency of L2 is stable when I add capacitance to L3.
I wanted to dial in 149kHz, but then the inductive spike/back EMF still appears in L2.
I need a clean sine in L2 with only the disruptive discharge, and without the back emf spike. This happens when I tune higher, so I will add some more capacitance to C4.
Re: new oscillator circuit shared By Nelson Rocha

Without ground to L3 the voltage of L3 is much higher, as it appears a inphase copy of L2.
Grounded it is much lower in voltage. but for tuning, this appears to be more correct.
Re: new oscillator circuit shared By Nelson Rocha
« Reply #157,  »
I will reverse L3 again, as the sine goes to the opposite direction when the discahrge in L2 occurs. So its not constructive but destructive for the sine of L3.
Re: new oscillator circuit shared By Nelson Rocha
« Reply #158,  »
hahaha reversed L3 but with no result, the phase is now reversed, but the dip in the sine is also reversed...
current draw is also the same. so reversing seems totally useless. I rather would have the coils line up with their windings, but I'll leave it reversed for now, as logic showed before, it was best when reversed.

So the only thing now is tuning L3 to max voltage, so we get the max power (current X voltage).
That 5W 8 ohm resistor will get even hotter then... it is already hot...

NASTY got zapped.
good I had a separate circuit braker installed, only the work bench went out. So thats good to know. It works!

I touched the Led light. I removed the lens to make it more broad. the 2 pins connecing to the the leds are bare naked I guess I touched those, as the system wasnt running.

My right hand is grounded (for protection agains electro radiation from the coils) and I touched the led with my left hand, got a good shock. felt like DC. Probably a capacitor discharge... pfew... never new those IKEA leds run on such high voltages...

A small resistor over L3 is basically a shortcut, resulting in low voltage high current.

I now have 24 ohm and 30 volts. not much, so i will make a larger resistor. of 100 Ohm.
I remember the lightbulb also was around 93 ohm when off.

I'll measure it again, and will try to make the same resistance.
this I do because when the lamp gets hot the resistance changes, and therefor the resonant frequency.

The 24 ohm resistor is 3 8 ohm resistors in parallel, ...
You do mean series right?  Otherwise you'd have 1 / ( 1/8 + 1/8 + 1/8 ) or 2.67 Ohms.

May I suggest a gas oven igniter:



The resistance still changes somewhat similar to a lamp, but not nearly so extreme.  Also very useful for discharging big caps or caps with very high voltage without melting wire and initiating that uncontrolled reflex to jump.

Another option is to get you a small spool of Nichrome wire so that you can have pretty much any resistance you want just by moving a non-insulated alligator clip around.  Wind the Nichrome wire on a stick of ceramic or high temperature glass rod.

tnx Matt  yes series
I have a hot air blower based on wire. maybe I'll rip it out
Re: new oscillator circuit shared By Nelson Rocha
« Reply #163,  »
I found my air heater. it works on heating wires.
got two coils series resistance is 111 ohm. perfect!

If I can tune it properly and it does heat up, I can connect the fan to the 230V mains and cool the wires.

that would also heat up the lab...

would be nice

nice connecter the heating wire straight to the coil. kept the ventilator intact so it can cool. inserted a thermometer to be able  to see a rise.

measured quick:
discharge now at 232 kHz with c4=15nf and c6=6nF
frequency is now slightly higher than before, due to the higher 111 ohm resistance

added 22 nf to c4 making it 37nF frequency dropped to 212 kHz.
i had expected it to become much lower.
So the resistance must be keeping the frequencies high.
Will also add more to c6
Re: new oscillator circuit shared By Nelson Rocha

no.... nelson said, when the load connects the frequency jumps up... pfff dont know what to expect. Ill just keep playing.
keep an I on the resonant voltages

made a new L1 coil.
more inductance, less resistance. this for a better negative boost converter

18.8 mH 0.3 Ohm
about 3.5 meter 1.5mm diameter soft copper enamelled wire

around a FT-240-43 ferrite ring diameter 61.0 mm u=850 AL=1075
bought from vandijkenelectronica.nl for 9.95 euro

it also fits inside the L2 coil so I might even couple it and see if L2 reduces current draw (as it normally does)

I removed all WIMA fkp1 caps again, as the seem unable to deal with the inductive spikes. Replaced them with WIMA MKP10 caps again. These always gave great results. The problems I had on lower frequencies are probably because, I started adding larger caps that were not MKP10.
Ordered more MPK10 caps for tuning.

D1 shows the L@ discharge in yellow and the blue unloaded L3 coil(grounded).
0.44A 23.2Vdc  L1 (toroid) is not coupled  F=117.93kHz C4=56nF (MKP10) C6=10nF C3 and C2 are open, c5=11.2uF

When tuned to higher frequencies, the inductive spike quickly appears again. Its still a mystery to me why it is gone. I assume the L2 resonance should be able to absorb the inductive spike energy into its resonant fields...

C5 isnt ideal, I need bigger caps that can deal with higher DC voltages. now its 2x 22uF 500V caps in series, but they are old (from an old fender hotrod amp). I remember these being bad.. will order new ones.

ordered 4 22uF 450V caps for C5  will make a series parallel setup giving 900V 22uF

The several hundred volts of dc always quickly faded away, and I guess it is due to the high internal resistance of C5. So now that will be replaced, I will have to be even more care full with the high voltage stored in side the capacitors.
new info from Nelson Rocha
« Reply #172,  »
Nelson showed his new circuit. looks like he reused some of his old parts.

What I noticed: L2 and L3 can be step up, but also can be step down. He showed step down voltage, which he called step up, as the current is increased. This means, L2 Has many turns, L3 has few turns (but ticker wire)

He also uses L3 in th middle of the stack, which makes sense. one side gets to see L1 (magnetic field) the other side L2 (series resonance with discharge).

L2 reduces the current draw of L1 when coupled (and working). 12V 0.62A uncoupled 0.25A when coupled. thats 0.36A less current draw.

All coils were clockwise. L3 had no capacitor, so this is pure to find the max current. Later will be tuning L3 for max voltage resonance and power.

He connected a car headlight to L3 and it lit up bright. he used his hands, so no high voltage. He also used another coil on top of L2 (3 coil stack) and used a bulp to light it up. So L3 can be inside and outside of the stack as long as it sees L2.

The " floating ground" is simply a battery that powers the pulse generator. So that mystery has been solved...
The car battery acts as a floating ground, as the source turns negative from the back emf.

MOST important:
It looks like C4 is a big capacitor. and C5 is the series resonant capacitor!!!
he pointed out the cap that is series resonant, and its near the power supply and mosfet, and C1....

Until now I made C5 large, and C4 tuned the series resonance... but it seems to be reversed.

I might need to make a NE555 timer, that can work on some batteries to connect to the floating ground, but for now Ill keep using the pulse gate drive transformer.
Re: new oscillator circuit shared By Nelson Rocha
« Reply #173,  »
Did some quick tests. Finally making more sense.
C5 indeed is the series resonant tuning capacitor. made c5 56nF
C4 charges up from the inductive spike of L1 with negative voltage, and when the mosfet turns on again, its quickly discharged to zero again.
 I made C4 0,2uF  which gave a slow negative charging until the mosfet discahrgs it quickly again.

It seems the negative discharge is fed back into the power supply when the mosfet turns on. This is dependend on th Rds of the mosfet. So a quick turn on and turn of but also a low Rds on will give best results. IRFP460 is what Nelson uses for this.

frequency is also much lower, 75 kHz.  but it is depended on C5, so I will play with it more and see how it al turns out.

I use the new toroid coil for L1, and the 111 resistor without capacitor on L3. The resistor gets warm.

So... need to build a new L3 coil with fewer windings thick wire. I got that...

Enough work ahead. Feels GOOD!
