Joule Thief

OK I made a start.

I connected the primary [ end of one and beginning of the other.]

The numbers 1234567 do not apply to the primary so I just drew the connecting lines.

In dark red, I drew the first side only of the pick up; It is coil J and it has wires #1,#4. (I am planning for the MK2 so I am going to keep these letters and numbers the same as they will be in the MK2 if I do it right!  )

Let's see how this goes.

Thank you Lady Jeanna !

That is going up winding counterclockwise and winding down counterclockwise.
Is the other side going up winding clockwise and coming down winding clockwise too?

if it is so, then only thing we need to be sure of is the directions of winding of the two primary coils and start replicating !

There is a drinking bird, and a drinking bird...

one of them is a funny thing that operates on evaporation, and another is an electrical circuit which pops at a given interval.

I would post a diagram, but my desk is a total disaster...spring cleaning is imminent.

OK Jesus,

Yes, It is woundjust the same as the MK2 before it is cut. The wires are #8, I am pretty sure. And it is coil number K
I took it back and made a change.

I guess you want to call the wires cw and ccw because we can know what we are talking about?

If you start to wind it, you see that when a cw wind turns back and goes down, it changes to ccw. If you keep the turning direction the same but reverse the progression of the winds, the cw turns to ccw. It is the reason it only matters for us to be able to talk about them.

I keep MK's drawing close so I get it right.
The split primary wires want to loosen up a lot so it is good to tape them down a little.

looks good to me.

Thank you @Lady Jeanna !

I will continue tomorrow drawing the whole thing for review by you and the other members.
The next thing is to get the accurate connections to be made among the coils.
