Joule Thief

[stprue]

lookey loo..

I just got 5 toroids and 1 rod.
They range from the size of a nickel US for the eyes to I think 2.4 inches for the mouth. Hi flux and higher flux u=60 and u=125 the big one is u=125
The rod is for a stubblefield generator. I will someday make just one more with this at the core.

edit add
@MK1 these are pale green in their real color.
@Altrez. wow. good going!

Jeanna those toroids look similar to the ones Hazens1 is using, did you get them from the same site?

[stprue]

WOW

you can tell when I get out of work can't you?

@all

Long time no post.

This is a schematic of a self charging Joule thief. The  battery runs the JT and the JT charge the battery back some points below its original starting voltage maintaining a balance indefinitely.
But if you add an LED it does not light.
It does not discharge the battery either.

Can you test it?
If it works as stated.
Can you improve it to work with a pickup coil that uses the same energy used by the original circuit and at the same time lights something?

I know that you have done it. I mean the pickup coil that uses no more energy than the one spent by the original JT and lights something for free.

Thanks in advance and congratulations to all that have had a successful replication of any kind of joule thief from this topic.

Looks interesting

Do  you   have  a working model ?

I  will play  with it  when I have some time  .......hopefully this weekend

Thanks for  sharing  it

Ac is more complex than just flipping polarity . there are three components to ac . Ac can carry thousands of different Frequencys at one time . The Most Common are one frequency . the sine ,the square and the trapezoid Waveforms. It can be made to Slow down or speed up . Ac can emit electromagnetic radiation in high Volume . Ac Is not By any Means Fully disclosed by Electronics theory. There is Undiscovered properties remaining in Ac that are not yet reviled .The Third Component Is Modulation . and that in it self opened more possibilities for this type of power . their is Fm am UHF Vhf microwave  and all these can be mixed or multiplexed on one wave of an ac signal . etc  Ac can be modulated to a wide spectrum of the electromagnetic wave band. therefor it is unique and a part of the JT Discovery ..
Gadget

AC is a modulated DC
it can be an amplitude, frequency, modulation and both.
the rate also be modulated and mixing is possible

i don't deny the AC waves complexity. there are infinite possibilities of shapes and rates variations.
but it still is a "tweaked" DC

can you give example of this : ?

Ac Is not By any Means Fully disclosed by Electronics theory.There is Undiscovered properties remaining in Ac that are not yet reviled .

the only things that are "undiscovered" about AC is its interactions with various materials that are not commonly used(read as "have not been tested yet").

@theNOPMy intent was to clarify a statement so that the people here may better understand what is happening in their circuits, the only thing I can offer is what is known as "common knowledge" in physics. For instance it is common knowledge that the electric and magnetic fields are the mechanism for energy transfer in a conductor not electrons, the electrons moving are an effect that occurs after the fact it is not a cause of an Alternating Current. If we want to understand Alternating Currents I think we should make an effort to understand "what" it is fundamentally. It is also common knowledge in physic's that the electrons move from the negative pole to the positive pole, this is called "electron notation" which corrects Faraday's mistake in thinking they moved from positive to negative. The negative pole is negative because that is where a majority of the electrons reside and these electrons have a negative charge. As well the "hole" analogy is a myth, there are no "holes" it is a bad analogy which is continually repeated in high school textbooks for the sake of simplicity.
I believe these facts do matter, how can we hope to succeed in understanding the nature of the circuits we build when much of what we have read in outdated textbooks amounts to an "urban legend" in this supposedly modern age.

i agree with everythings you wrote.
your intent was not misunderstood by me.
i am even happy to read your explanations.

i did not remembered the exact way electrons were moving relative to the polarity, that is why the remark and question mark about the holes.

even if the electrons movement come after the fact, i think it is still usable for the sake of describing that the flow goes from one side to the other then back to the start.

the holes myth came about for 3 reasons.
-guys like me, who were teached with the "holes" stuff, for the sake of simplicity as you said, talking about them without mentioning one basic fact, forgetting that not everyone had the same education.
see below.
-the student not paying attention at a critical moment.
-or an omition of the professor.

my prof teached us that the holes were not actually real holes. Duh!

they are "places" where electrons have a pre-disposition to go for start orbiting an other atom.
this is not the real explaination.
it is what i made out of what i was teached about it.

there is a reason for teaching us the holes stuff, the complexity.
a knowledge that is not critical unless you intend to do physic recherches.

thanks for you post, that reminded me my old time.

@all
there are a few other things like that, that are only fully teached to those who take advanced physic classes.
even for an electronic technicien or EE, it is not required to know the exact process that make the electrons move to do a good job at repairing or creating new circuits.

unless doing physic researches, those knowledges are not needed.
it is wrong to say that those knowledges are not available, because they are.
you only have to search for the right things by theirs names.

note that those are theories, not laws.
the direction of the electrons, or, of an electric current are use in multiple laws formulas, but it is rarely needed to know the underlying process of how that direction is established, it is enough to know in whitch direction it goes.

regardless of the direction convention you choose.
it is either the reality or it is its mirror reflexion.
it is a paradox because even if it is a mirror reflextion, it is still the reality.
when you look at yourself in a mirror, is it you or something else ?
there is nothing in the reality that is not also in its mirror reflexion and there is nothing that is in the mirror reflexion that is not also in the reality.
i think that it is the reason why nobody fully rectified Faraday mistake about electrons direction.

No,
I don't remember who it was that posted it... was it altrez?
http://www.cwsbytemark.com/
Their server seems to be down today.( I kept it in my bookmarks for parts and it won't come up). Just save the link for now and look later.

These are more expensive,  but the permeability is way less than what the site Hazens posted quotes. u=60 and u=125 Who knows ?

They are a greenish color and are called chokes. I think it is where MK1's toroid may have come from. Or something like it. These cost 35 but the shipping was 12 so $47 all together. I waited to know I couldn't get the cheaper kind from other sources to work as strongly as MK1.

I will let you know. I am sure you know that by now!

@jesus,
I would like to make your circuit mostly because it is so clear, but I don't want to make it if you have not tried it yet.

I am being overly cautious, maybe but I do not want a battery to explode in my face because I am giving it 100 times too much because I am making a little mistake with a diode.
