Successful TPU-ECD replication !

[gn0stik]

Wattsup, the inside diameter of the large ring should be such that the wire loop is 6" in diameter.

The OD of the small loop should be such that the diameter of the wire loop is 4".

The coils should be wound directly onto this form to achieve the wing shape as mentioned by otto and ronotte.

As far as the diagram goes, not sure what you mean.

Thanks for your reply.

If the CC should be wound directly onto the ring, then we must consider that cOmster's replication is not per Otto spec and the distance (air gap) between his coil and ring could cause a decrease in transfer potential.

I guess that when we see Ottos CC's with the side flanges, we all assumed that the coil was wound on a core and slipped into place on the ring. This is a major difference. Geez could have saved me hours of grief in trying to find the right core with the right diameter.

So that answered one of my questions. Thanks.

In terms of the diagram, is it possible for someone to draw the mosfets with the three connections and show which one goes were. Not a circuit diagram but more of a pictorial.

@cOmster

Great video of your tests.

If we use the same frequencies as Otto, the TPU must be built exactly the same with the same coil and ring lengths, etc. Since no-one will be able to make the exact same replica, (although we will come very close), the frequency will have to change to reflect the resonance of the particular rings and coils.

Also, when using one frequency, it's easy enough. When you have the first frequency and introduce the second, you will probably have to readjust the first one also since the second introduced frequency changes the dynamics of the whole tpu. Again when two frequencies are found and you introduce a third frequency, you will have to play with the first two again because the third frequency will change the dynamics of the first and second. Once all three are adjusted to work on your particular TPU, you should see Ottos results.

This may be why your bulb decreased in intensity with the third frequency. You may have to work with the second and first again with all three working. Resonance is when all three frequencies work as one. Once you have found your resonance, this should be repeatable on your TPU, every time.

Wattsup, I know there appears to be a spool there but if you look closely at ronotte's doc it becomes apparent that those are simply pieces of cardboard to aid in forming the edge of the coil, and it is, in fact, wound directly onto the ring and tube..

Lindsay pointed out that my coils were wrong yesterday, after I had wound them for the second time. Ack. Here's some quotes from their doc.

This setup is shown in the next picture for
the 6? ? 4? ECD. In the Fig. you will note: the 2 Mobius collector loops one inside
the other (glued to the side of a silicon hose used as support & shape), the
3 small transformers 120? apart, the heat sinks & Mosfets put near the loops,
the wing shaped solution for the coil support.

And...

This was the time when Otto did post on Overunity Forum the ?Wing approach design?
for the shape of the Control coil & and a practical approach for implementing & positioning
of the collector coil itself.

So I don't know how much this will effect the operation, but in order to compare apples to apples we need to build as they did. So, here's a pic of my 6" ring. (no 4" shown) This is my third and final winding of my controls. (unless someone else finds something wrong with them.) If you think winding is a bitch, try unwinding a bifilar coil to rewind because you don't have enough wire to redo it from scratch. Yuk.

Like the purple tape? I thought it was a bit dull looking so I added a bit of color.

So Lindsay, hope this one's ok.

Rich,
yes I think so..
I have my collector 90 deg to yours as this was Ottos first method ..the doc stats either way..just so we know one difference here.
I am usung non conductive black fuel hose..another difference..

As long as we know differences they shoud be of assistance us..
Of course it is not very likley that 2 will be the same however we do it.

How far have you gotten Lindsay? Have you noticed the effects otto has? Rotational field and all that with this setup?
