@timmy

The zener diode will limit the voltage coming out of it to the specs of the diode and dose stabilize the output but limits the voltage,I am not sure that is what you are looking for , i was thinking of using some my self but to limit the voltage to recharge a battery or feed back to the system .

HOW THE CIRCUIT WORKS

" The transformer is configured as a BLOCKING OSCILLATOR and the cycle starts by the transistor turning on via the base resistor.
This causes current to flow in the main winding. The other winding is called the feedback winding and is connected so that it produces a voltage to turn the transistor on MORE during this part of the cycle.
This winding should really be called a "feed-forward" winding as the signal it supplies to the transistor is a positive signal to increase the operation of the circuit.
This voltage allows a higher current to flow in the transistor and it keeps turning on until it is saturated.
At this point the magnetic flux produced by the main winding is a maximum but it is not expanding flux and thus it ceases to produce a voltage in the feedback winding. This causes less current to flow into the base of the transistor and the transistor turns off slightly.
The flux produced by the main winding is now called collapsing flux and it produces a voltage in the feedback winding of opposite polarity. This causes the transistor to turn off and this action occurs until it is completely off.
The magnetic flux continues to collapse and cuts the turns of the main winding to produce a very high voltage of opposite polarity.
However this voltage is prevented from rising to a high value by the presence of the LED and thus the energy produced by the collapsing magnetic flux is converted to light by the LED.
The circuit operates at approx 200kHz, depending on the value of the base resistor and physical dimensions of the transformer. "

that's how it works, as simple as that. no puzzle at all.

nope there is far more to it 

need a link .... 

check out my  6 freq controller thred 


ist...

when you all get it right you will scare the shit out of your selve if not get electurted in the process...  BE WIZE....

it is this

BALANCED RYTHMIC INTERCHANGE  for the millionth time .....   

when you get it right you will discover speed does not matter ...  keep the dam thing way out of resosnance!!!!!!!

ist, i've told you a million times not to exaggerate

i've read your thread. sorry, there is nothing of substance there, no circuit diagram, no pictures of circuit, no video showing operation of circuit, nothing, save some cryptic and enigmatic references to some puzzle that you claim to have solved but won't/can't demonstrate and we should just "figure it out" or "get it right". all of this is from you, the guy who didn't believe it when i lit a fluoro tube with an AA powered inverter circuit. in fact you didn't just not believe it, you called it a fake in not so many words. this behavior makes your 'advanced' knowledge extremely suspect. you can lay it all to rest by taking the time to actually post the components needed and each step taken or better yet, a circuit diagram for your 6 freq controller. if you want to contribute with substance, great, we are all for that. mumbling something in enigmatic, cryptic half english does no one any good and only serves to clutter this thread.

@all
First of all this is going to be a long answer, as many posters have asked me questions.

@jeanna,
Testing equip, I had to go without to get this stuff as I could see we (I) really do need it.
Is ithe waveform complex, no not really, its just good to be able to see it on a cro and the frequency meter (I made a boo boo it should have been KHz not MHz, sorry all)
Thanks for the http www pat 2 pdf org, I see Mr Mag has provided the patient whilst I was putting in zzzzzzzzz last night.
(well I gotta sleep too, even if it's upside down to you lot) 

@mk1
Yesterday I took a yellow torid off a PC SM power supply and stripped the wires, rewound it the way I thought and put it aside to sleep on.
I noticed you posted the right way to wind it, lol, oh well, I live and learn, thanks for the post mk1
see photo0194.jpg

MrMag,
Thanks for posting the 381970.pdf for us all, TA.
I will have to put it aside and print it out when I get a printer that works, mine decided to blow a hole in the flexable membrane that runs to the printhead. The Canon PIXMA MP760 dosen't seem to like doing book size runs lol.
BTW I have ADHD, does this disqualify me if I fall short sometimes? My grammer is not perfect, and you should see my spelling, its actrocious, and my maths is dreadful eg 10+10=1000. 

@pirate (bill),
I don't know much about maths, amps or frequency, there are others here that are better than me, (way way better) but my way of thinking is this.
DC voltage is just a volt output, it is a constant flow of electrons.
if we begin to alternate this constant flow, or twist it upsidedown, backwards and forwards, it turns into AC, if we do it fast, it becomes 50Hz in australia or 60Hz in USA (etc). If we make it go faster and faster and faster, funny things happen to it, it seems to behave differently, than if it was just a steady voltage. This is what is happenning in the JT. Then someone mentioned "radiant energy", so is there actually 2 different lots of electrical energy? Wel that is my humble opinion, and as I am not a electronics tought expert I can only know what I have picked up.
Amps I think is the amount of push the electrons have behind them.


@ ist
I love your little quips and smilies, but behind them I can see you know a great deal more than you are letting on. hmmmmmmm
I can see you are steering the forum this way or that, guiding us (as we all are in our own ways).

I spent about 3 weeks reading Ironheads forum (HHO), now here is similarities between JT and Ironheads forum, but you have to read it all to find what I meen. (resonance frequencies is the key to all this).

@ amigo,
Thanks for pointing out my mistake, (big bite of humble pie here lol) you are right, I had miss read the instrument, (it even had a green LED lit up on KHZ like a bright lighthouse ha ha) It is just on 20years since I used a cro properly, (im rusty) and have no experience at all of using a frequency meter, I am constantly learning, and a new instrument takes time. I decided to buy these instruments as I knew I would need them to replicate peoples ideas they come up with on this forum and the Stubblefield forum. (just commonsence).
I suppose it's a bit like joining wires together, we can twist the bare ends together, and it will work, or do a better job by soldering them.

@timmy1729
Darlington Transisters, someone mentioned, plonk it in the circuit, if it dosent work, change it around or swap the polarity.
If that dosent work, try making a darling transister yourself, use 2 geranimum transisters instead. I think they have a lower turn on base voltage.

Phew, this was long, teach me to go to sleep...........lol

@ all

My first double jt. Base on tesla pat. and replication of photo0194.jpg.

This is the unit that uses a pnp and npn transistor , at first there was 2 led on it one on each side now replaced by the 2n4007 diodes
With only on jt connected both led lighted , first on powered and second by induction.The red green blue and yellow winding are like the picture on earlier pages and have each 12 turns like the picture,copper coils there are 2 of 48 turns going on 180 degree 2 times so back and forth.
Each side gives me 30 volts.

@electicme

How many turns did you manage to put on it seem to be good for the secondary (4 pickup coil) .
