when a paper contain more occult and suppression theories then provable scientific faqs, i call it a novel...

Nop disregard that one , if its not for you , but the other ones are still worth reading.
But honestly , fiction doesn't really exist , and the occult by definition is secret , and only for the ruling class of this world,
Don't take my word for it, the truth will not be televised , quand radio can , raconte des mensonges au nouvelle de 6 h , c'est pas facile de comprendre , ou de savoir la verite . Meme la soit disante mytology grec , quand Platon et c est solide platonique son't en avance sur nos technologie et compreention moderne, et que la republique est aussi une vraie description du monde moderne , la verite n'existe plus . La verite est quelque chose de personel .
Si tu veut commence par quelque google video sur la fleur de la vie. Aussi fait des recherche sur bohemian grove,
Apres , on parlera si tu le desir . Mais regarde ces video seulement si tu est pas trop religieux , si non ca peut t'affecter.

I found this one, the coil could be put on a toroid , this should work on 1.5 volts . it could be a way to have a single kicking coil, leaving more room for more pickup coils or we could do a dual circuit so two coil in a pull push config.

MK1,
Thanks for that fabulous book. I will be reading it all day 514 pages. Tesla speaking to audiences demonstrating his ideas etc. Much was normal back then and forgotten now. It is so amazing that they were setting up experiments to watch the sparks and wonder at them. Fabulous. He also has named names of those who described alternating currents before him. Very nice. Thank you.

Quickly,
Thanks Jim, MK1 Bill  and anyone else for the appreciation.

@Dog812,
In series you need more volts. That is the reason lighting 25 of them or OMG 58 in series is significant. It shows a strength in the system that is not needed in a parallel arrangement.

In parallel if you have one that is more "open" to current it will take it and the rest will suffer and, I think??, it could blow because it is getting too much.

I am not sure if one going out will kill them all at this higher frequency we are using on the secondary of the jtc.

My guess is that if you take the time to make sure none are much brighter than others you will be ok. Maybe make tester with a very high high resistor (150 ohm) and 2 batteries on a breadboard and just pop in all your leds 2 or 4 in parallel and see how they look in comparison. Maybe you could make one like that for all in one HH. Get the resistance so high you can only see a dot of light. That ought to be an easy way to check for even-ness.
Maybe throw a red in series first to make the whole string behave for the test.

Anybody else with a good and easy way. ?

@AK,
I am not sure how to accomplish what you are wanting. If you put the cap in there you seriously lower the voltage spikes, for one thing. And anyway, where could you apply the probes to see what you want to see in oscillation? Between the base resistor and the battery neg? Between the bat pos and the tap? Through a resistor?

Also, have you looked at the mag-amp. MK1 has periodically presented us with mag-amp links. You can more easily find these on Bill's circuits thread. I have seen them there.
The mag-amp makes oscillations without a transistor. It uses a cap and pot in parallel together between 2 toroids.
(I will be playing with this but have not yet.)
It does it by means of a relationship between 2 cores and 4 coils and different rates of magnetic flux. It is something I need to come back to . I am not able to think in those terms yet.
Butler winding web site has more details. I think MK1 has posted the link in the other thread too.

OK, I'm back to 1894 and Tesla giving a lecture.

syl,

@all

I think this is what Jeanna is taking about , crating a pulse from resonant circuit made of one resistor and one cap.

[jeanna]

Oh this is cool

Remember how I noticed a reciprocal relationship between frequency and volts?
But, it was surely not linear like ohms law. and it was definitely always going in the same reciprocal way.
It never reversed that part.

In the lecture I am reading NT refers to this and proposes a 'law' which he has not proved and which he says would be very difficult to prove. (No kidding. without a scope - very.)

light and heat from a spark, which I would perhaps consider to be watts?
so, substituting watts for light and heat from a spark:

W=F x V²

W= watts (or pico watts)
F= frequency of oscillation perhaps in Hz because this is what he was using
V = volts

EDIT: On further thought, not watts, but something that has the same or similar effect but is NOT watts. ( - I like this idea.)

Anybody who wants to try that today before I get a chance, have at it!

EDIT ADD
this is too sweet. We already know his sentiments but this is so hopeful. I put it here because we are fulfilling his goals now in this century on this forum.


... "We may be producing a practical illuminant on these lines. We would then be simply using burners or flames, in which there would be no chemical process, no consumption of material, but merely a transfer of energy, and which would, in all probability, emit more light and less heat than ordinary flames.
