Joule Thief

[Koen1]

@Mark/MK1, @MrMag, and a little wave to Pardon

Well it looks like MrMag has hit exactly the same snag as I did.
Transformer theory does state that one primary with N turns
with 10 secondaries with equal number of turns each, is similar to
having one N turn primary and one 10N turn secondary.

So you see, MK1s claims of getting out 120V 10A in each secondary
seems entirely contradictory to transformer theory, which states
each secondary much see only 10% of the total voltamps, and in
total all secondaries together must see a total of 100% the input.
Minus losses of course, but that aside.

This is exactly what had me confused (and is starting to get me confused again );
MK1 seems to have been claiming to get the full input energy from each
seperate pickup coil, while I have tried and just don't see that happening in
my little experiments...
... what I see in my experiments seems to be exactly what transformer theory
states: when I use 1 primary JT and one "pickup" coil, I get out almost exactly
what I put in, which is almost exactly what the basic JT puts out without pickup coils.
When I use multiple pickup coils, the output per coil drops. When I decrease
the number of turns per pickup so that the total number of turns for all pickups
combined is equal to the original number of turns on a single pickup coil,
and I wire them together, I effectively have a single pickup coil again and this
puts out exactly that same power.
I do not see that every pickup coil puts out the full input power individually.
I see them put out a total that is equal to the input.

So Mark, I am not out to debunk you or anything but I still am quite
amazed at the output you are getting.
I just don't get it.

Do you think it has something to do with the core material you are using, perhaps?
I am just fishing for possible explanations here...

Kind regards,

Yeah,
I just tried another one.

115v on only one secondary wire makes this my best jt toroid.

I clipped a 24 inch alligator clip to the other side of the wire while the scope was reading it, and let the clip rest on the floor, and the volts shot up to 237v.

Maybe I am the only one that missed this, but if not... there it is!

Jeanna I have also noticed the effect of touching the coil and seeing the voltage go up . Its producing a strange reading much like  a Fugi circuit being read with a dmm . Goes crazy reading voltages from it . Possibley due to Very High Frequency or maybe Rf ? ,I'll try and wrap it with Al foil then ground it say at the screw on an electracial outlet wall plate . .

@koen1

I never claimed 120 v 10 amp ? You guys are really good at not making any attempt to understand, what i am saying.
Its just real sad...

@all

Now that we can get so high voltages with a single AAA battery. I was watching a video from @lidmotor about a LED box he made that utilizes the swap switch idea from @kubikop.

I made a composition of the circuit mixed with @gadgetmall's tank (pot and cap).
And after understanding the way the switch swaps the battery I thought that we can create if it has not been created already, a commutator to do the same thing automatically or a very well done and simple enough flip flop situation, that will swap the batteries all the time while the motor or circuit is running.

In this case it is a Joule thief circuit. But it can be used with a pulse motor after attaining the desired inexpensive on parts and on voltage or current used circuit.

also we can just use it as @kubikop designed it and switch it every day.
Any opinions, ideas?

Hmm well okay maybe you didn't actually claim getting that output,
but when MrMag posted the following:

Lets say I have a transformer that has a 1:1 ratio. This same transformer has 10 secondaries on it.

What I am saying is that if I feed in 120V at 10 amps, each secondary will have 120V at 1 amp.

What I think you are saying is that the outputs should be 120V at 10 amps each.

Is this what you are trying to say?? Maybe I lost something.

you did reply:

i think all coil will have 120 10 amp each.

So indeed you did not say you are getting that as actual output in a working JT,
but you do seem to be suggesting this is what is happening in your JT setups...

And all I am saying is, exactly what I have been saying for a while now,
that when I test that with my own JT, what I see is exactly what MrMag describes
and is exactly NOT what you describe.
The reason this has me somewhat confused and frustrated is that I really want to
replicate that disproportionally high output that you describe, but I haven't seen
a single hint of such disproportionally high output in any of my own tests.

You guys are really good at not making any attempt to understand, what i am saying.

Well I find that a bit insulting to be honest.
I've been trying to understand how you get that disproportionally high output for quite some time,
otherwise why do you think I keep bringing it up? I can assure you I do not do it because it gives
me pleasure to keep whining about the same subject... although I admit it may look like it does
I went quiet and stopped bringing it up for a little while since nobody seems to be able or willing
to say much about it that makes the thing understandable, and in fact nobody else really does claim
such disproportionate output, apparently.
But now that it was brought up by MrMag again, hey why not revisit the weirdness.

Its just real sad...

Well, from my perspective it's more frustrating to hear you repeat the same story about
a disproportionally high output which does not appear to accord with transformer theory
nor with my own experiments.
I am trying to understand what you are saying and so far it does not appear to make sense.
This is not due to unwillingness on my part. I want to believe.

But hey, if it is impossible to make us understand what is apparently a clear picture in your mind,
and if this results in you becoming frustrated or fed up with my replies,
then perhaps I should just shut up, conclude that you are apparently magically seeing output
that nobody else sees, and stop worrying about what seems to be a very interesting discrepancy.
I don't like to do that because I prefer to understand things and this is something that does not compute.

At the moment, however, it seems like we're in a sort of stalemate, where you keep repeating
your view which involves an output of N times the input with N pickup coils, while I and MrMag now too
keep repeating that transformer theory says input and output energy must be equal and there is
no magic multiplication of the output by increasing the number of coils. That is clearly not getting us
anywhere.

I don't want to upset you or anything so I shall try to refrain from posting anything regarding this
stalemate.
If you feel like trying to explain what you do see and I am apparently missing, I am all ears.

Kind regards,
Koen
