it is repaired .. that was odd ...

anyhow .. looks like garys secondary is feed back ... 

perhaps ...

Albert,

Mail me your JT drawing in a bigger size that was in your document.
I will update the word document and mail it back to you.

Alex.
Done . I have a zoom button so it ZOOMs right in on that little pic . I could not for the life of me figure out how to enlarge that dang tinycad drawing with the information in the bottom right SOO i just sent you the diagram .

@Gary,
Thanks, I will stand by and watch.
I am not clear how you are using the external thing and how it is called a secondary if it is external??



Jeanna

Look at the  the 2 first pictures  you posted for me.

The  first one is called  Candy Cane
The second one  is called Candy Cane2
The only difference in the coil is the 2 extra windings that I added  AFTER all the other windings  were done ........and after I had  written down  all the voltages I  had got  from the original  windings  .

What wouldl you call  these new windings ?
I called them external  .....because they are external to the original  windings and core

In the 3rd picture   you will see a simplified  version  ......it only has  2 windings ........the primary is  a brown and white twisted pair ... it spans several toroids . .
The  secondary   is the orange wire  that I called  external 
I did not have enough  space in the  center to add more  wire to the secondary  .......a bigger  toroid is needed


hope that this helps


gary   


IST  no feedback ........yet

Thanks Gary.
I guess it is just called the secondary. That is unless it is the one that is connected to the transistor which would make it the primary.
I believe that the secondary is what it is even though it encompasses all those toroids.

My conical is not as much a secondary as it is another coil in series, because it only has a few wires wrapped around the toroid, and the rest are going off to who knows where as a 2 wire cone.

Both of these are pushing the boundaries of our definitions and I want to stay on top of them, because I know I will get confused and eventually lost if I don't.
So, thanks for the explanation.

Jeanna

here is something else to stay on top of

:)

This  is a different configuration  of  my candy cane  coil
Like  my  candy cane coil  the primary  of this coil  spans several toroids . ( brown )
The secondary  goes through  the centers of all the toroids  but does not wrap around any of them .

The  secondary   ( orange ) originally  put out 50 V measured  with a small cap and a bridge
I tried  lowering  the  voltage  by  increasing   the base resistor .
I had to add 18K to get my pot to a workable range so I could hit 2.5V
At that power setting  the ultracap did not charge   

I  did not  take reading and  figure out  how much the ultracap was going up per minute .......but with full power this coil  was charging faster than candy cane3 did the other night . probably  because of  a larger  secondary 

The  green coil  is there to  experment  with feedback ...... This coil  did not  have much power     I might have got the  windings the wrong direction 
With other  feedback experments  this coil  would light up my LED array very brghtly

Wow ! that took a lot of time to do . It is running on 1.5 right ? Nice design and i might add that's quite original !

@all


Gary , nice , out of the box thinking unless you are making a small hadron collider ...

Be careful not to open a wormhole.

All my thinking is out of the box thinking .......... I never could afford a box to put my  thinking in


:)


Gadget    yes   its 1.5 v

What I wonder   about this coil ...  If I used big enough   toroids  and  a  large secondary ....... could   the secondary work off of  E field only?
As it is set up   this coil may  or may not  be using  the E field.

In order to reduce diodes losses,  maybe they can be joined in parallel up to 2-3 items?

WELL SIR GARY

NOW ITS ON!

i mean that in a good way bro .... lol

i have something im gonna try .. but  just similar to what you have but i will step up the origonal jt flyback  and dump to external secondary then to your loop   

im gonna build it  right now ... 

and i will make  basic mk2 jts.. so i can FEED 2 CORES FROM 1  to BOOST VOLTAGE HIGH FAST ..

is

i made a 16 turn twisted pair cat5 1" goldmine as a supply ...  took a pic ..

the design soooooo fits the pic ... lol
i will likely make 3 like showen then each a mk2 jt  or even a 1 with 2 windings like the w core ..

i guess we will see what i end up with lol

Great video Pirate!  Everything was explained well!  Looks like you're getting lots of light out of that CFL.  Is it a 13watt?

im  makeing a basic jt as showen 16 t

im scopeing the out put ... i have noticed some intresting things....

WILLIAM

i will add the video ..  im getting nice peek to peek spikes ..  over 100v  as i tune it ..  i can go for verry high freq .. or verry high volt .. at a lower freq..  if i HEAR THE JT ... IT IS RUNNING FAST ..

if it is silent i have high volt spikes 

that turned out awesome bill!  : )

im makeing a few videos ...   in my first video i will show you HARMONICS ... ON MY SCOPE!

the harmonic bands are located on the PEEKS OF MY SPIKE... in this such unit ... you can CLEARLY SEE THEM!  lol

Thank you.  No, this is a 9 watt (40 watt light equivalent, according to the box)  I have some more work to do.  I think I can get it much brighter with a little tweaking, but we will see.

Thanks bro.
