@ Mannix,
Thanks.
I added another question while you answered my questions. Let me repeat that one: Do you have one or three primary coils?

@teslaalset

Don't use your PG in pulse generator mode, use it in square wave generator mode and set it to a fix 50% duty cycle. 50% gives the best output signals (what you saw on my scopeshots).

33 ohms may give you lower input current than necessary. So if it's too low, please adjust it to lower resistance. With that coil configuration your input should be around 100mA 200mA if you want to see positive results. When you have completed the 3 coil drive it will rapidly fall below it.

IMPORTANT

I will write it multiple times again but I hope this time everybody will read it.

1. I noticed that many of you're trying to use PG instead of square wave generator. Expect the best results at 50% duty cycle. Below or above you will get worse results. (in some cases 10% adjustment may bring improvement, but don't vary it, leave it on fix 50%)

2. Frequency: no need to go to high frequency range. Stay in a FIX lower range (e.g. 100Hz or 1kHz). It is not a radio device.

The video you've posted is embarrasing but also extremely funny. All those coils have exactly the same problem and I am wondering if any of you were able to expect serious results.

When I cleaned up Stefan's I will also send you photos of my poorest devices with far better results and you're going to hit a hole in the wall with your head how simple they are.

This thing surely pushes something like dc around in a circle, in one direction around the unit

Yes and if you put a load on it should not show significant drop on the peak voltage.

Lindsay did you save your previously opposite wound coils? If so, what do they show? Thanks

Mannix

Are you saying that you are pulsing the outer wraps, the ones we were thinking were the secondary output?
And you are seeing dc on what we thought was the primary?
And if your scope is not hooked up while seeing these "visualizations", I fail to see how you can determine dc, let alone see accurately what is happening. For all we know, the capacitive form of not physically having the probe on the test point, could be out of phase.
I dont see why a scope cannot be hooked up. There has to be a way to make a resistor network to protect the probe from this dc or crazy large pulse.
I suppose we will wait for Gates.

Hello Altair,

I have answered many of these questions but I agree with that there are too many posts and the noise level is also high in this topic to find the answers. So naturally I will repeat it to make sure everybody has understood everything. Later I will make a FAQ to these questions and use it a signature in my posts to make your life easier guys.

could you tell us more about your theory, what are we trying to accomplish here ?

We are building an electron accelerator. Each primary coil passing a wire at multiple points with some picosecond delay that creates an extremely fast electron flow in the secondary wire.

Is there an optimum wire spacing ?

I didn't find optimum spacing yet, only minimum spacing which is 2x of the diameter of primary wire so far. It doesn't mean that you get worse results below it, but it means I didn't try it yet so I don't want to nod for now.

Is it preferable to have more volume inside the windings, ie thicker tube, or thinner is better?

I increased the tube diameter on my coil to make me easier to place the 2 more wires between the first one and guarrantee that they will not make an echo if they are too close. The wall thickness is not important, only to make the whole thing hard enough to work with.

Would it be preferable if the secondary was on the inside ?  Or totally enclosed by the primary?

No, I didn't observe difference in operation. If you wind one with secondary first, you only need to make sure it will be far enough from the primary wires running INSIDE the tube because that may cause disturbance. (we dont know more specific about this, need to be verified later)

I wind the present coil with secondary firs because I use a very thick secondary and don't want to damage the thin primary (as I did recently).

Is the sequencing of the 3 phases important?  1-2-3, 1-2-3 ect...  or 3-2-1, 3-2-1 etc...

Very important quesion, as probaly it makes difference. For a few hours I can not verify this. (My glue is bonding very slow and I am still sticking ) If you have the opportunity please try it in 1-2-3 and 3-2-1 sequence, also change positive and negative and please share us your results.

Is the steepness of the leading and trailing edges of the signal important?

The slower rising/falling edge gives lower back EMF. Please use a current limiter resistor on your primaries (15-22ohms) that will make soft rising/falling edge and make your device voltage driven instead of current driven.

What is the effect of pulsing 3 phases with overlap compared with DC current?

If you pulse one primary, you will have to receive smoothly rising peak without back EMF oscillation. The pulses will be very far from each other, but by increasing the frequency you can get them very close to each other. The minimum distance you can achieve between the pulses is about 1/3. So the output pulse will be about 33% duty cycle. You can not get them closer by changing the frequency. But if you fire the 2 more primary you can fill those gaps with created new pulses and decrease the input current. The optimal input current is about 100mA or 200mA depending on your configuration.

Are we trying to create a vortex in the aether?

No. We are "sending" electrons in a primary wire that OCASSIONALY passes another wire (secondary). When you have low amount of intersecting points over the secondary wire, you will trigger the electrons to flow spontaniously in the secondary in one direction. The primary then going inside the tube where does not meat other obstacles (secondary wire) and can earn some speed (some psec) and coming outside again to pass the secondary wires as close as possible.

In this manner the secondary wire will provide DC current.

When you will drive the 3 coils, please make sure you start it from low frequency and increase it slowly as the spikes will come closer and closer. If they rapidly merge your coil may blow up.

My last scope shots that shows 3 spikes was driven at ONLY 87Hz and the duty cycle of the 3 output pulses were ~50%.

What is a particle accelerator?

Particle acceleratior in a regular form is a device that creates flow of particles in a medium. Usually in vacuum where the low weight particles don't hit resistance. In the normal CRT TVs there is a particle (electron) accelerator that creates a stream of electrons in a thin beam. They hit the surface of the screen and light fluorescent dots on it. another unit in the TV moves this particle beam in a "zig-zag" pattern from the top to the bottom that makes the beam able to scan the whole area of the screen.

In this device we don't create electron beam in vacuum, rather we do the same thing in a conductive medium. Since copper is a very good conductor, we can create the same high speed electron beam right in the medium and use the beam as energy.

If we had guidelines, we could probaly unite our forces, and synergystically add our ideas.

Yes I agree with that.

Keep up the good work.

I am on it.

One simple question:

How do you connect your oscilloscoop probe?

I connected mine with the ground lead to one coil connection and the signal lead to the other coil connection.
Would be good to know if you did exactly that as well.

Oh, sorry. I have forgotten to answer that question.

I have tried both ways, it doesn't make any difference, even with load on it.

That's why you are here right?
To show us how it's really done.....
I sugest you bring it on.

Yes marco. Thanks for pushing me it is vital. Please make a bot repeats your comments every hour.

Well,
I tried 50% duty cycle signal as low as 75 Hz, increased the primary peak current from 300 mA to 600 mA. It's a no go.
Next, I will make a new coil with 45 degrees single winding primary to see whether that will work for me.

[update]
Yes, I tried switching the polarity of the primary.
Yes, I tried turning the coil setup upside down.
Yes, I tried a 32 ohm load to the secondary coil.
No go, guys.

Below some details of my failing coil, just for the record.
Primary coil wire : 0.2 mm
Secondary coil wire 1.52 mm, 3 windings
