MK1:

Thanks.  You raise some good points here.  I was hoping to "tap" into the coil via induction to fill one cap.  I have to be careful as these SCs (supercaps) are only rated for 2.7 vdc.  2 of them together might handle the 6 volts, but it is still pushing it a bit.  I need to get more of these little boogers, maybe some at 5.5 vdc.  I have to wait for more $$ to come in.
When I get more time, I will try to catch up to you and the others with the secondary windings, etc.  I just need an entire day to experiment with all of this.

PS  I gave you and all of the others here a "+" for the Karma thing.  If it were really like karma, for every "-" someone gives, it would come back to them as a "-" as well.  Inverse for the "+".  I don't take it personally because I think it is kind of dumb.  We all have much more important stuff to do.

@Mk1,

At the risk of ostracization for mixing with someone with as few karma smites as yourself , might those 3 frequencies be dc, magnetic, and cold electricity ?

@Bill,
Thank you for doing that and timing it. I do like the idea to use a supercap as the ultimate rechargeable battery.

Some idea on what to do next ,we will need so see how it works when it is feed by a pickup coil , maybe making a special one just for it with as many turns then the jt coil to get the initial impulse back, the real big problem i see so far is to feed it 1.5 volt because i have made experiment with higher voltage on the regular joule thief and at 3 volt you get a 40% lost in energy(it could be limited at input but the jt output about 6 volt at the led and would need to be down at 1.5 in the cap) . But if you only take as much as given it may be enough to get resonance, self resonance.If we can get it to resonate we could tap that energy real easy .

Remark on the TPU unit, it needs 3 freq , its like 3 note make a cord on a piano or guitar we should think of that when tuning it.

MK1,

Could you provide some closer details on that 40% loss of energy, please?

I have been repeating last night's breadboard jt experiment only I am starting at the edge of the board. I just took a break before I continue.

I want to add the bit about polarity. It is such a strange thing.

I wound the first turn of the secondary and saw nothing. no light... so I turned the led and it lit brightly --this is the free hanging led, mind you, not the one that is part of the jt. I will give more details later, but since I am breaking, I took the chance to say this.

I made the decision to have the leds of the secondary start on the neg side so I wound this first wire of the secondary the other way around.

I would not want to say cw or ccw because this changes if you put your observer's eye on the opposite side, but the other way makes a difference,

It is a cool mystery.

Anyway, about the tpu thought. I decided a few minutes ago to use smaller multiple secondaries and see how it goes with 15 more lights. I'll be done with 15 more lights tonight if not more. I'll let you know, of course.

Thank you,

jeanna

@Cap-Z-ro

I have had a lot of tough on those same question and my conclusion are, magnets and and electricity are the same it is just the angle you look at it, they are 90 degrees apart, but are the same thing , If you have energy in a solid state it is impossible to see unless it is agitated , So if shake the hell of that energy you will see its potential.Freq is a wave , a speed , a sound , if you get the right maths like guitar a major cord sounds like it fits note (but sure a augmented cord would work better, since it is more symmetrical), but with more volume but it took only the energy from 3 single note.The issue then is tuning the cord so that the toroid vibrates, if the core is under magnetic stress it will show its potential, each toroid core as a freq depending on its size and composition.

To me so far dc seems ok since switching it on and off you get the same as a effect as ac up and down , Not switching will not work since it only transmit its energy when the field collapses.

So lets make them sing.

Then the pickup coil are details.

@ jeanna

I made some experiment with the regular jt with a 1.5 volt source and a 3 volt , with the help of the pickup coil and bridge diode I tested the effect of voltage on the output and it was lower on the 3 volt then on the regular 1.5 volt , that means that the resistance at higher voltage would need to be adjusted , but since it would be then constantly changing its real hard to do.So we need to feed it a lower voltage but as many electrons or more but at 1.5 volt, As i can now see since your last night experiment that 1 turn is really powerful and we can put many of those.


@all

Magnet are magic , but you know that since you are a kid. Show me electricity a will magnets.
