This is  what  I call a long wire JT

The  JT coil is nothing more than  about 6 Ft of  twisted pair wire .
The  first  picture is   just  the  longwire JT  lighting  a single LED

The second picture is   the same  wire with few  wraps  of it around  a toroid .  The  secondary of  the  toroid is powering the LED array .

The 3rd picture  is  of the same  setup  with  2 more  toroids  with both of these the   secondarys   are being used for   feedback .

The  toroids I used for this were  not wrapped  just for this  test.
I removed the primary windings   and  wrapped  a few turns   of  the longwire JT  where their  primarys  had been.

About   using heavy  or light  wire.

I find that with my JTs  wire guage  is not  very important on the primmarys.
I  do not  push the limits of the primarys
I intentionally   keep my  transistor biased at  well under  half power  so that it runs  cool.


If    you think you might  need  heavier  wire for your secondary ........ I suggest   you use several  smaller  wires  wrapped  as one .   It gives you many more options   
The  windings can then  be used all in parallel  series parallel or  in series .........or separately

It took me a while to  understand   how to use it ...........but   now that I have thought about it a while .......there  is a bunch of  ways   you can use  a wire once you get it pulsing .

Is this really 101?
-----

I have made a picture of 4 toroids wound in various ways.
This is just to share the size and variety possible.
I did not include the enormous 3 1/2 inch one.
On the top left is one wound in the "normal" fashion. The black and white are the primary bifilar.

On the upper right is an example of one that is hard to use experimentally because it is all the same color. I cannot tell the primary bifilar from the secondary without a magnifying lens.

On the lower left is my favorite.
This is 0.5 inch and the other day I was able to wind it to produce enough to light a neon or a string of 32 christmas lights. 172 volts.

The lower right shows the medium 5/$1. I found the best tuning for it is 5T to the base and 6T to the collector.

Both the toroids on the right show a little trick that helps when the secondary wire is so thin it doesn't want to stay in a breadboard, or it breaks. Solder a short piece of 24awg telephone wire to it and it works... until it breaks off.  ;)

j

Jeanna

Yes    that is the name .

If it ends up meaning  anything depends on the whole  group

It may look like  I am  only trying to show  people what I have done .
That is not the point .
The  reason for  this  thread is to try to  get people up to speed .
I can not teach  people what I do  not understand .

I can show people what  I know and  try to get them to think ......that is the  best I can do.

If this  thread is  to be of any real help to  others   we  will need  others  to share  some of what they know ......  Others  have did many things  I have not done .........I will  not  try to explain any of those things because I do not   understand  them  well enough .

gary


Edit

for  this  thread   to  be of much help we will also have to keep the posts like this one to a minimum.   
Most of the posts  should  have the intent of  helping someone  understand  something about   a JT better .

i have over 2500 pictures  of coils and such i have wound scope shots all that stuff
im just a little too left handed to have it all neat and tidy ..

air core
iron core
copper core
feroite
steel ie screw nail .. whatever ..

i have built all of thease ..

they all work it is almost impossible to not build 1 that works lol

i even used all steel wire the darn thing still worked

ill round up some pictures .. of odd things i have done and add them in this thred 

all are basic jt's  if you go air core on a solder spool you can go iron wire center pickup.. then you go tesla hair pin!! bridge the gap out to the cap ...    :D lmao

and bang it slower .. power right off garden wire ..

the thing is you cant go wrong .. 

i have used silver wire all diffrent gages .. and many many cores every colour ...

magnets no magnets  1 2 3 freq rappid seccussion  random wild ..

npn pnp 

i colud literly go on and on ..  all work the same ...

here is a picture of my accidental tesla mini jt...

displaying radient spark from 1 wire ..

rectified and here is the youtube video ...

quick cold charge!

db107 bridge

ist!  i forgot to mention this can be dubbled for output .. this is only 1 side and i can put as many as fit on that core ..  however i so desire ...

was over 500v till the kick back from the cfl ;) fryed it ...

here are a few 2 freq scpoe shots from a basic jt this is what happins when you intrurpt a jt ..

running at its natural freq!  8) :o

basic jt scope shots

ist

see my FAST CAR... jumpping across the screen?   this is a 2 freq RECONNECT ON SCOPE  8) 8) 8) 8) :P

Hello all,

WOOOOOW, so nice JTs!

And not 1 pf of stray capacitance.

Maybe a bigger diameter of your cores with coils?
