Joule Thief

[jeanna]

@ist,
I am going to work on the lower right corner of that secondary today.

I am not sure what you are asking about extra long.

They just go off to the right and never end. (Maybe that is what you are asking about?)

Today I will be splitting the wire on the bottom into a Y.  Well from the picture it will be --< .

Then from that, which has 2 wire ends, I will add an inductor and some leds. I have not found a cap that helps with this setup, so I may not use one and just use the inductor.

I plan to keep the 10 series leds in the place where they are.
They are there to show me what is happening to the toroid.
If the lights brighten or go dim on that set, then I know I have done something to the toroid.

So, I do not know if I answered your question.
Feel free to take the picture and mark it up.

I believe this circuit is what we all should be using.
We can toss the little box... Well, it is fine over there using the battery and running the basic joule thief.

Thank you,

jeanna

im not sure how that works yet

 

altho i think it may work   i dont know how to put my thoughts to words right now on that ... 

sorry

i will try at some point but i have not done ANY expairments with the close couppling effect yet ..

ist!

but it works cuz the flow in the wire .. and another being close to it as i understand .. weather it is a 12vdc battery and 2 wires .. there is potencial in the wires all the time weather the circuit is closed or not ..  ;)so if they were fairly close there would be interaction i think one could tap ...

and yet not drain much at all from the source .. i saw this in the way you left the wires long on the secondaries ..  plus i have had some chats in the past with a few people bout this kind a thing ..

but i have not tryed it ..

@ stprue

Jeanna has been assuming that the MK design provides better performance than a regular solenoid coil. My test have not shown that to be true, but I am only one experimenter. ...

... I am still looking for some experimental evidence that the MK design produces better results than a regular solenoid coil but no one seems to want to do a direct comparison test.

If the MK design is better, I would like to see some tests showing how much better it is.

Hi xee2,

I actually have a shoebox full of the ones made in the solenoid fashion that do not work. I can't do much testing because they are so miserable.
There is one test you could do on your setup to see.

Make the solenoid go past the middle point and see what happens.
I made this kind of thing over and over. I first saw slayer make one this way, then hazens, then hazens again, and again one more time. Finally I had sworn off making them this way when you got the big toroid. 80 turns turned on a 4 watt fluro. very wonderful.
Will 300 turns triple this? will it increase after it crosses the center line?

I think stprue came up with a good solution in his latest wrapping design.
Maybe it is finished, or will be today.
Then we can see.
In examining the tesla patent about that winding, it became clear to me he used 2 separate secondaries and made 2 separate circuits from them. He never even tried to combine the 2 sides into one circuit. Well, I haven't seen it yet, if he did.

I agree with your frustration in not having anything to compare these things to.
Your solenoid showed that my assumption of having a better result with a more wavelike high frequency shape was not at all correct.
What you did is very valuable. - and I thank you for it.

After I am too tired to proceed today I will go through my notes and give you my data on these solenoid coils, but I really thought I had, all over this thread.
It was the reason I kept getting no results.

Bye the way, I am getting 160v on the one from yesterday and it will not light my little neon.
It also seems more 'reported voltage' is needed to light the neon as well as the fluro.

thank you,

jeanna

@Jeanna

Yes the coil is half done but looking at it before I stopped working last night I noticed that once again the primary looked to be while wound correctly, like it was going to mess with the rotation.  I have made up my mind though, and I will finish this one anyway.  If it doesn't work I will wind the primary ( this should really be plural) in the mk2 fashion and maybe backwards, we will see!!!

what about a 30 v jt to power a fet to switch it in that time .. with a higher voltage and amprage mimicing the same as the small coil in a big one .. ? 

it will probally work as a good timeing and tuneing device .. 

to control a bigger one .. to use as output ..

agin  i do get lost in the million posibilities and ways of doing all this .. 

you could do this with MOTS... RINGGGGG them with a fet in 2 TIME PHASES ..  AND 2 FREQS..

collect from the mots then neo zap it to a cap or a  100W LIGHT BULB......

hummmm

ist!


i just drew a picture of this on paper last night ...  if my drawing was not so messy i would post the drawing .. but ..  im not going to as i have not built it yet .. 

besides mk1 might want to do this ... but the mk2 coils were bifillar both of them 1 was npn other pnp in sync ...  wired in revirse of 1 another .. but both wound the same way ..

agin 1 million ways ...
