Buy me a cigar
I have a couple of questions please?

How does the probe work? Is it directional? Will it be reading the flux from both sides ( placed between the gap )

Is there a method to calibrate the probe using known electrical formulae?

Cheers Grum.

How does the probe work?
It has charge carriers that are deflected sideways by Mr Lorentz in a slab of semiconductor., just like we are trying to do in the fuel ring (but circularly and with fast electrons). This is also known as the Hall effect.

Is it directional?
Yes, it is sensitive only to the perpendicular component of the flux. (perpendicular to its surface).

Will it be reading the flux from both sides ( placed between the gap )
Yes, the magnetic flux has to penetrate the sensor (go through it) for it to work.  It is not a probe that reads on its surface.

Is there a method to calibrate the probe using known electrical formulae?
Yes. You would have to build two Helmholtz air coils of very precise dimensions and connect them in series and apply a very precise DC through them, and put the probe exactly in the middle between these coils.

Yeah, but how many ampturns are needed to turn that flux in the gap by 90°  now ? 8)

I am printing a new coil former which should house these 530 turns of 0.8mm wire so i can make some measurements again.

Verpies,

You can also do calibration with a reference magnet.  There are a few low cost ones available on ebay with +/-2% accuracy.  Tighter tolerance references are available at higher cost elsewhere.

Still waiting on that patent.  Do you have a title, number, link, or any other clue that would let me search for it?

You are absolutely correct but Grumage asked for a method that "uses known electrical formulae".

I promise you, I will post it here.  I just have it on a computer that is in another house.

Verpies,

Thanks, I'll try to be patient.  I am anxious to read the patent as it seems you are talking about some sort of nucleonic transformation/decay (dare I say transmutation?) that causes the nucleus to emit fast electrons (instead of high energy photons).

I would think that with all the spectroscopy research over the years, using NMR, EPR, ENDOR, etc., someone would have captured an anomaly related to a nucleonic event that released fast electrons and that there would be many papers published on the subject.

Please let me know if I am still not "getting it".

What time zone are you in ?
Check the link in my post mentioning that patent, tomorrow.

Verpies,

I'm still trying to wrap my head around where the fast electrons come from.  Something related to nucleon modification just seems a bit of a reach.  How does one remove or modify a nucleon without that being a high energy event involving the emission of high energy photons or particles?

I can possibly envision a fast nucleus flip that causes orbital electrons to be ejected, but outer shell electrons are relatively low energy, and ionization within a conductor would likely be extremely brief or involve few or low energy electrons.

Ejection of inner orbital electrons would be much more energetic and would not require nucleon modification.  Possibly flipping the nucleus fast enough, and perhaps with some shielding provided by outer orbital electrons having coupled to (resonated) with the nucleus, there may be some mechanism that would allow some inner shell electrons to be emitted and act as you suggested in your previous post.

I'll have to wait for the patent.  I am both intrigued and befuddled...

Verpies,

TZ is EST.

It would be more obvious and a bit easier to find if you could post the link in a new reply.

Thanks,

Latest vid from Andrey245, looks like Aluminium has a mayor potential.
It looks like a Bunk kind of setup.

Yes, what does "Bunk" mean in this context ?
In English, the word "Bunk" does not have positive connotations.

The Russian title of the video states: "Bunk mania".

Maybe, maybe not.

He is not doing these experiments methodically. Just tries random things like some members of this forum.
What is the thickness of the aluminum roll ?  Diameters ?
What fields is this foil subjected to ?  Magnitude, direction, frequency, type?
( these are not questions to you Ape )

I find it curious that the bulb lights up only after he disturbs the wire junction with a screwdriver, like  a "kick-start".  Most electronic oscillators do not do that but there are some that do.

No I mean the " Bunk" setup..

https://youtu.be/BmyOjsjzHi8?si=Kg3ferTG-Q5eJLOz

What I do know is there are 2 pieces of foil.. 25:75  length scale and a thin NiChr sparkgab in between.

Oh, you mean this.

The topic of this thread is "Установка Бунка & Гуглодрома" which translates to "The device of Bunk and Guglodrom", which must be the names/nicknames of the authors.
If you keep reading that thread the Bunk persona is also sometimes called "Bob" or "Wow".

   It means that it is a replication of what a guy named "Bunk" has shown. His forum, or TY name is Bunk.
   
   Ape:  I once tried to connect a single 120v grid phase line to a 50w bulb, and then the negative end of the bulb to my earth ground line. This was to see if the house meter could be fooled. And it did light the bulb, but would not light a 100w one. So, maybe try a smaller bulb. like 25 to 50w, doesn't have to be a halogen bulb.

  I have also tried just using my Kacher to light normal old style bulbs, through the rest of my grenade device, and earth ground but, without the PP being on. And the bulbs lit, as well. Up to partially lighting a 100w bulb, just from the Kacher, and with yoke/grenade all normally connected, but without the power on. I have a video of that, if interested. It is something like Andrey's video, but, using the Kacher only, to power through the grenade, to power up some bulbs, instead.
    The screwdriver kick start, was how some of the Joule Thiefs had to be started as well.

Yes, I believe your rigth.

...or a slotted tube made out of one sheet of foil wrapped on some carcass.

Where do you see a sparkgap in this video?   How do you know it is made out of NiCr ?

Another thing that I have noticed in this video is that the mobile left and middle low-turn coils are wound oppositely (CW and CCW) and they are connected in series (so their magnetic fields are bucking) and the light bulb is connected in series with them, too.

I don't know Andrey uses a SG.

Yes the output coils are connected as you say.
Could they be electrostatically being charged as if it was magnetic induction the bulb would have no voltage.

Mathematically speaking, the incandescent bulb's brightness depends only on the current flowing through it, according to P=i2R.  There is no voltage in that equation!
I would like to see the shape of current flowing through this bulb. This is easy to do with a current sensing resistor  (and even easier with a clamp-on probe).

If you know how to ask him a question, at least ask what his frequency is.  In Russian: "какая у тебя частота ?".
If you feel really brave you can also ask him about the shape of the current waveform.   In Russian: "Какая у тебя форма электрического тока, проходящего через лампочку?"

I dont think something will come up as Bunk himself is not on the forum for a long time.
Therefor I can see if there is something available.

I did not mean to ask Bunk but Andrey245.

If the power supply is supplying 10ma @ 32VDC then it is not enough to light an incandescent bulb like that.

The only way is that his primairy coil is not as we think it is... sounds wierd but could it be coax and connected as a cap.
Else this kacher config would easily draw 15Watts
