I wanted to try the double back non inductive coil, as a core.
You Smoky believe that there is no driving the core and you may be right this, and all the stuff is accomplished by bucking coils + a third coil.
Now I wonder what to do with Bruce's theory, and if infact its an undriven core.
Theres much experimentation, for a machine. Many many designs.
I think you missed it.....
It has little to do with the bucking coils.
That’s just his way of amplifying it to make it usable.
Something Stiffler should have spent more time on.
The receiver is on the outside.
That $&88 in the middle could just as well be wired off to the side as an external circuit.
Make 4 pancake coils. Two are 2x the size of the other two.
Follow Stiffler’s instructions and tune one to a freq. you can produce
Either with a signal generator or a timer circuit, etc.
Use that one as your reference, and wind/unwind the other pancakes until
they all spike at that tune.
Next drive the One big coil from the signal.
Put a cap across the other and sandwich it between the smaller ones.
Now bring the coil you are driving close enough for the stack to pick it up.
what you do with that output it up to you
You will need a capacitance and an inductance to get it out of there without
destructively interfering with the stacking signal.
You can do this in pretty much any way you choose.
think of the two toroids in the middle as being a 4-coil transformer
Even though it has two separate cores, the math would basically be the same if
it were all one inductive mass.
In reality there is a difference between the two, which it is my understanding that
this causes an inefficiency. because they are sloppily wound.
(and a subsequent beat freq. arising from the difference)
it really doesn’t matter.
The way SM is doing that is storing it in caps between the coils to form a tank and
Kick it back to the receiver.
they weren’t all bucking coil dual toroids. And half the time he covered up the middle circuit.
probably because it was too simple to show anyone.
You’d think at least some of these would be replicators at least grew up with a crystal radio kit....
We’ve lost and forgotten more than we could ever teach our children.....
