Agentgates´s TPU setup with strange wavehill hump

[Mannix]

@watts up ,
exactly! too easy to change the effect and the correct starting point .lets see what Tony saw..then move on.
It not like it is expensive to build

@ gadget
that generator of yours could be gold (acording to SM) for this  but do  a better coil .. you know that.

@nightlife

Down the road a bit for certain , but for now who gives a rat's where it comes from?

If it is a means of remote power extraction its still fantastic!
None of the other inventors could completely justify its source .We just might find out .
Im not setting up in a bare field just yet. I like the hole explanation ..just for now though.


@tony
Thanks again for your sharing and do try to not let the negativity get to you whatever the various outcomes people get.
It would not be the first time that something was difficult to replicate due to yet unknown influences and abilities.

What a great find you made , I can almost see the tornado effect just looking at this thing , I do expect the right way to harvest the holes as you well put it ,another challenge.

I used a post tube that is 80 mm ..an A4 paper sheet fits the circumference exactly so marking it out is much easier using the paper with marks on it . come to think of it whatever the size cut a sheet of paper to the circumference and away you go!


Many dis-used cable reels have a nice former inside some heavy cardboard some hdpe (plastic)

I will fire this up tomorrow with various generators , wave shapes and voltages

On a very side note (from a PC hero without any testing skills):
_{I am sure some of you thought already about changing the 45 degrees later on.
I was thinking of a variable angle toroid, which would have a plastic ring on top and also at the bottom (for holding the primaries), and these two could be twisted independently from eachother, connected with a plastic rod in the middle of the toroid. Of course, the upper ring would go a bit up/down, in order not to damage the primary winding.
In other words, the primaries would be sitting on these twistable rings, while the secondary would be still on a PVC/toalet paper  .
Thus, you could tune the angle while the device is turned on.}

Tony,

Attached is my proposed 4017 circuit.

Alex, the resistors R1, R2, and R3 are *extremely* low in value.

The base-emitter junction will have so much charge injected into it, that it will take an eternity to pull the charge out again.

I detest using bipolar transistors if it is at all possible to use FETs, even if this is what Tony wishes for the time being.

In any case, the base drive resistors should be more like 100k or higher, and have a small ceramic capacitor in parallel to help in emptying the base-emitter charge when the drive signal transitions negative.

Until the "mass circuitry" is eliminated as SM says, I would suggest using a shift register rather than a decade counter.  More on this later.   In the meantime, for circuits, consult my 2007 post at
http://www.overunity.com/index.php?topic=2582.msg38506#msg38506
to see the advantages of using shift registers over decade counters.

Earl,

Those are bipolar transistors so there are no charge.
The circuit will perform OK. I made the circuit as it
is because that was what Tony wanted.

Negative.  You are totally incorrect.  It is well known in EE that bipolars need injected charge into the base-emitter junction in order to be able to turn on.  In order for a bipolar transistor to be able to turn off, all this injected charge must be removed.

This is why every experienced EE uses base resistors of appropriate value.  A low-inductance capacitor in parallel with the base drive resistor is not optional, it is a *MUST* in order to increase speed of both turn-on and turn-off.

To further increase your knowledge of BJT, you may refer to
http://ecee.colorado.edu/~bart/book/book/chapter5/ch5_6.htm
where it says:
"As long as significant charge is still stored in the base region, the collector current will continue to exist. Only after this excess charge is removed, will the base-emitter junction capacitor be discharged and the BJT be turned off. The removal of the excess charge can take a significant delay time labeled as td,2 on the figure."

I have observed with an oscilloscope probe in my hand how too low a base drive resistor will cause an unbelievably long turn-off time in a BJT.
