AC from Joule Thief Secondary/pick-up

Hi Jeanna . Nice Drawing with those little coils do you want this to produce more voltage ? then if Yes we need to add a tank circuit . if you don't mind can i take your schematic and add to it

I was hoping you would...
The little coils is a paintbrush on photoshop. Imagine my delight to find that! One click makes a perfect circle and a line makes a coil. Changing the 'font size' changes the diameter. cool.

. the next thing is multiply the outs, which one  ? all of them need higher volts ? Ac and or Pulsed dc or rf  ?

All of them, but one at a time for now, otherwise it is a jumble.
My preference is to start with a tank in one place then move it on to other places.

The tanks can be straight cores, or they can be additional jt cores.

Very Busy even thought I'm retired

yes, well now you have enough time to be really busy!!

Thanks Gadget,
I added one more jt core last night and read some readings on meters.
This is going to be very interesting.

I want to clean up the glyph of the toroid a little so it can be used and expanded by people.
In its formal normal config it would have 5 wires.
I want the possibility to clearly add more secondaries off the one coil glyph  too...
so it is clear that it is toroidal, and it is a transformer etc.

Oh good, I am glad you like the drawing. I am glad you are still here.

OK here are 2 glyphs to use.

Feel free to change them for yourselves.
Even make suggestions... etc.

Jeanna thank you for the description, I will make another attempt at making the MK.  You didn't make mention of the cross overs though!  So I don't actually cross over any windings either outside or inside the diameters of the coil, right?  Looking kinda of like an XXXX  I'm guessing!


It needs to look like this //////////up and then returning ////////////////////down?

I thought I did?
Oh well sloppy cutting, I guess.
Yes there has to be a crossover.
Make it on the inside as we talked before. I think there is a pic of a blue toroid somewhere that makes it easier to see the cross over.

I think really what will happen will be:
\\\\\\\\\\\\ up and /////////// down, but when you do them make every effort to be ||||||||| on the outside.
That way the XXXXXXX will be on the inside where you have less room and an overlap is better anyway.
That ought to scramble anyones brain who has not tried to make one yet!

I missed your post. I am sorry it took so long to answer.

ALL OF MY COILS WOUND IN THE MK1 CONFIG CROSS ON THE INSIDE ... 

IST!

If anybod has good pis'c of this winding please post for me

I will retry a very simple one to make sure I have it right.  Not too long ago I made one with 26gauge mag wire.  I made it exactly as you describe it.  Going up when I got to the top I checked to make sure it was producing voltage which it was I believe like 70 or 80 volts, which considering I hadn't gone back down yet and it was only one side really good!  I wound back down crossing over on the inside and remaining lllll on the out side and crap results!  After throwing it and yelling a few choice words I began unwinding the back down windings and I watched the voltage go up.  It looked like the way I was winding back down was canceling the winds up. Anyway I will try again!
