Joule Thief

@all,
Introducing the SOP4 Toroid JT.


OK you all have heard of single Phase, Double Phase, and 3 Phase, Hear is my 4 Phase
Special Out Put Toroid 4 which I will call it SOP4 for short.

I wound this just a couple of days ago.
It consists of a standard JT exciter coil/s and the the primary output coils are like this.
I have not connected it to any other component as yet.

I cut 4 wire strands 3 meters long, (3 yards approx), then wound the 1st output coil on the JT.
Then after sore fingers, I put the other 3 wire strands in a batt powered drill and zoomed them up, into a single one, (should have done this with the other one).

Then I wound the zoomed coil on top of the 1st coil.

This makes the 4 seperate coils as the output coils.

Next I plan to connect all of one of the 4 ends together, similar to a "star" winding configuration.
BTW, there willl be another source of energy at the combination point, but it will be less than half of the other ends, it is "floating" energy.


The other "free ends" will be connected to my "Bridged Array" which consists of 8 diodes.

Jim

It  looks like we think alot alike




I have a couple  solonoid  coils that I made  quite a while  back .........before  the  NS  earth  battery  thread .
I have one  coil with  4 pairs  of wire and another one with 6 pairs .
My plan  was to   drive   one pair  with  a signal .
another pair or 2 was to be resonate circuits .
One  pair would be used as output .
My theory is ....... you can;t  tap all of the energy ........   you have to tap it indirectly  and leave enough   to let it keep ringing .

I never  got it working .
I  still think it is possible  .........this was one of my first  tries at buildinig

Oh yea !! I would try a 2n3055 with this one . I have one that has been running for a week now on 3055 . its running 5 20kmcds leds and one 115 kmcd and one 100k mcd . they are turn down a bit but the battery life is doing great for 2n3055 . resistor is 100 k cap 104  . now i dont have your baby there im running a normal jt with 30 turns and 80 turns for the jt . running the lights off C E no secondary .
Cant wait to see this one fire up Jim .

It may change the frequency. You have a frequency button on your meter, don't you?

jeanna

I have 2 meters that have  frequency now .........but neither of them have  high frequency .....  if I remember right just  up to KHz
I have not used  that feature much .

I was thinking we/you could use one of those fuji transformers that has 1700 turns in one of these tests.I have always assumed when you say flyback that you mean the same thing as back-emf.
I am asking just to be sure.

that is a good  idea ...it might allow me to  use   smaller  coils for flyback too.

yes ......  flyback  pulses and back  EMF   .......same thing .

So, you put the new coil in with not a series connection as much as a connection to the tap - wherever the tap is, and this makes the whole thing oscillate.

Am I getting there?
In my mind there is one wire left without a connection.

For flyback I am using  a simple  series connection .
With my multi  tap  coil  I am pretending that the  windings that  are  not  connected  are  just not there .   
In reality   they may  be  active  .....but I think  that  the majority  of the  signal will be from the  connected  windings .
I am just trying to get into the right ballpark ..........a coil made up  for the specific   JT would have to be tuned anyway .


Just thought I  shoule   clarify a little .
I said I was using  a simple  series connection .
I have been using my  LM coils  for the most part .......  I have been  hooking   one   side of them   in series with the  load .....  sometimes   I connect though the  secondary side ......sometimes that side  chokes the pulses .....   so I  connect which  ever works .
I then connect the other side    for  feedback to source

There is no extra  wires ....... 

all the  flyback  coils are in series  ......all the   feedback are  in parrallel  with 1   diode  for each coil


I  have one  coil that I tend to hook up  first for  feedback .
it has  2 full  coils of the  #22  radio shack wire  on it  (bifiar ).. ... it  is  good for feedback   .....and not to bad for flyback
even though  this coil  is  half   and half  it is still hooked up  exactly like the others .....flyback in series  ..... feeback  in parrallel

@all

And???

This is what I see Nathan Stubblefield did.
He always seemed to have his generators in pairs.
I see them as a twisted pair of one copper and one iron wire we called the 5 and 6, twisted like the center tap of our joule thief.
Then these 2 were connected to another twisted pair of the other one.
And there was always this globe thing on the top (which is what I believe to be the sparkler. Inside like a vangegraf on the inside making the make and break.) He said you must never do anything with them... (the red and blue on the bottom and the top = 2 sets of these sparklers which equate to our transistor as in the C and E in the JT circuits)

And it was the secondaries that produced all the effect.


YEAY!

How does it perform?

@Jeanna


Real well !

the loading effect is greatly reduced , i am still tweaking , this is part of a bigger circuit that has 5 toroid , i am releasing it in part the dummy was the second part , the mk the first . When i give them they are independent , and useful on there own , but they all work together.

Floyd Sweet and Lester Hendershot also used it , i wonder about Marks ?
