Joule Thief

]Is it the same way as the Joule thief coils are connected?

Definitely not this. The up and down takes care of the switch back.

I still have the same question.
How do I connect the two pickups in series?

No, Or maybe, but  just make them and see.

I believe series is right, the part that you will not encounter until it is finished and right in front of you is that when you finish going up then down the first time, you see that what used to be cw has turned to ccw. Then your head begins to spin. So, Mark is right, (again!) just make the 2 pick ups then test each pair for the best voltage then solder them together.

I say this because even if you were to keep it straight while making the MK1, which I did, you will have a much more difficult time with the MK2 and then exponentially from there because with each new increase, you will have 4 wire ends to put together.

Plus, I believe, not sure, the better voltage from the MK2 comes from some added induction in some wires and it is not necessarily the best to keep them in series. I am not sure.

Later, I have a thought about keeping track of them so we WILL know, but for now, lets begin.

If anyone is not ready to commit real wire to this, it is possible to mock it up with string. Just to see what happens and how much wire to cut to not waste any etc. I like string.

Here is the promised graphic.

We need now to get the best pickup coil connection in order to get the most output.

from what i make of the right most toroid, you are showing a end to end connection.
it must be end to start

the middle toroid
the arrow is confusing, the arrow should be on A1
B2 should be ending under the toroid like A1
the way i have build it, all coils start and end the same, the arrow should be on the J labeled side.

i find it simpler not to end all the wires at same region of the toroid.
each coils start and end at it begining and are easily identifiable.


same here:

Yes, theNOP,
It is true.

The A1 and A2 on the drawing should be reversed.
EDIT: no that is wrong the drawing is correct.
thank you,

The A1 and A2 on the drawing should be reversed.

i have not noticed that, but now that you are saying it.
yep, that also.

Jesus

First the jt coil are used in the regular jt circuit way, you connect them if it doesn't work then connect one of the coils the other way around.

Now the pickup coil are not connected to the circuit in any way , once you are done making a mk type pickup coil you can if you chose connect them in series , i usually test the 4 ways they can be connected since i don't always start on the same side of the toroid.

To charge caps they do not need to be connected in series , on the mk8 i charge 16 caps fast without serial connection
if i do connect them in series i will only have 8 cap charged faster higher . is it more , i cant say .

First build and tune .
