Great job Rosphere. It looks like wrapping these coils is going to be a real challenge, and we thought the TPU was hard LOL.

@Rosphere

That coil is a work of art! Can't wait to hear how it works!

BTW what film is your avatar taken from?

Acerzw

Thank you, gentlemen.

My current avatar is a scene from, "It's a Wonderful Life."  Jimmy Stewart plays George Bailey who has just found himself in Pottersville, instead of Bedford Falls, to see what life would have been like if he had never,... shared his energy secrets.  Everybody buys their energy from Mr. Potter.

I may be off on a few details.

It probably makes no difference which way I wind.  I can always switch the wire leads on one coil

I agree here. I think I remember in the video Robin mentioned the flow was opposite but the coils are wrapped the same way. I know it?s a lot of work wrapping those coils and hats off to you for the great work. If once you connect it up and play with the sines and there is no affects then perhaps as a last attempt someone could try wrapping a different coil a different way. But that is up to your own discretion Rosphere, use what your intuition dictates.

In Marko's Videos he talks about XYZ vectors.  1 and 8 are the x axis, 4 and 5 are the y axis, 2 and 7 are the z axis.  Now if you look at how the coil is wound you can see 1 7 4 and 2 8 5 vectors.  The 174 vector is plus and the 285 vector is minus.

I'm not sure about what you want to do with the second opposing winding that you are going to wind, would you be so kind to detail?

Hello, Roberto.  I hope that you are well.

Yes, It is difficult to describe with words alone what my question is regarding the winding of the second wire.  Since I am at work now, I have no time to make and post a drawing for clarity.  Referring to the figure that bocas posted above, I already have the red wire wound as shown (1 7 4, 1 7 4, 1 7 4,...) and my question is about winding the green wire.  There are two ways to wind the wire along the green path; to start-off winding over the top of the form (2 8 5, 2 8 5, 2 8 5,...) or to start off winding under the bottom of the form, (2 5 8, 2 5 8, 2 5 8,...).

Some have advised to wind the green wire in the same direction as the red wire and I can reverse the current if need be.  But this little voice inside keeps telling me to wind in the opposite direction.  I can not discern if this little voice is the voice of success or the voice of failure.  If I do wind in reverse and it turns out to be wrong, will swapping the current flow also work in this case?

I think the winding difference has to do with the direction of current flow from one wind to the next along the perimeter.  Perhaps I will make some detailed drawings showing what I mean after work today.  My issue is really quite simple, yet difficult to describe.  If you were in the same room with me and I had my coil in hand then I could show you what I mean in less than thirty seconds.  Perhaps I should make a short video clip.

Rosphere--more later

wow Rosphere. that looks like a chore to build. Sure is preedy tho. Nice to see you around again.

Hello all,

@Roberto

use at least 10 wires in paralel and wind the 2 coils in same direction. Make then 1 ECD control and pulse this little TPU.

A warning: your scope probe should be NEAR the output, not connected.

Otto

Here it is.  More later.  Off to work again.

1 more idea go get rodin 

I emailed him through his youtube account to come here, but I doubt he has time.    We'll see.
