Some tests on mono and bifilar coils

[MileHigh]

Conrad:

Your scope can do all the mathematical operations including squaring a waveform.  Pretty impressive, it's all so simple when it comes to the guts.   It's possible it's just a motherboard inside the box running Linux.  So it's possible to generate some interesting waveforms.

Your transformer should work fine on the ferrite rod but it will have less power transfer capability than the equivalent toroidal core.

Gyula:

Thanks for crunching the numbers.  The lady is exposed!  I remember the "delayed Lenz effect" craze about two years ago.  Farmhand spotted it also.  But to make a better case you need real numbers.  It's a pity that this basic measurement was not done very often.  I don't watch many YouTube clips anymore but I don't recall seeing anyone making the power measurements on a delayed Lenz effect clip.

Without the load, the high dissipation was "insured" by continuously maintaining the resonant high AC current circulating in the LC tank by induction from the rotated magnet, the induced voltage across the tank was 22.8 V RMS, while in the loaded case the induced voltage was only 7.6 V RMS (the 100 Ohm attenuated the LC tank) so inside the tank the circulating current was also less, (loaded Q, induced voltage and circulating current in an LC tank are interrelated of course).

Exactly, and I have one thing to add.  There were comments about no load with the signal generator driving a parallel LC resonator and the pick-up coil as an LC resonator when you connect a capacitor.  They are not the same circuit at all.

Farmhand:

I posted before how myself and Poynt were on a thread with Thane looking at one of his new setups.  To put it bluntly, it was yet another nonsensical magnetic circuit.  Also, he clearly did not have 'it' - the ability to demonstrate competence and knowledge in analyzing his setup and using his equipment.  I was a bit shocked.

I also suspect that the 'big reveal' about the 'delayed Lenz effect' may be the mechanism behind a lot of his older clips from four or five years ago.

Hi everyone,

Thank you Conrad for starting this excellent topic and sharing your research results.

I would like to share a video I made today of a Bifilar Toroid I am presently testing since I am presently also testing the benefits of Bifilar coils.

Link to video demo: http://www.youtube.com/watch?v=cQe49jH_3lA&feature=youtu.be

Please note an error in the video, I keep saying the time division in micro seconds when it's mostly all in milli seconds.

Also, please use the link below if you wish to comment about my video so not to create confusion in Conrad's topic.

Quote from Farmhand,


"The BiTT is another nice piece of sillyness. Claiming 1000 times OU with less than flea power and drawing lines on the scope.. Pffft. What a scammer. The piper will come for his dues from Thane, and all the other scammers. I'm surprised NASA allowed him to use their responses to his emails and demo's mentioned to be for them  for so long. If I was them I would have forced him to remove any reference to NASA from his you tube page and his website ect. They look bad enough without associating with scammers like Thane.

In my humble opinion Thane probably paid  the Overunityguide entity to do the tests and post the results and tests that he did for him, a true shill was Overunityguide. No sign of him before or since and no other subject was touched on by him.

It's time Thane was outed, as the body of evidence showing he is actively lying to push his agenda is substantial and damning in my opinion.

How much time and experimenter effort has he caused to be wasted ? And how many people has he put in danger trying to replicate his lies ?

To Thane, come and post in this thread. And explain to us why we should not denounce you as a scammer or a misinformation agent".


@Farmhand,

This is some pretty damning language coming from someone who appealed to sensitivity towards others in my case. Thane's an acknowledged inventor with excellent academic credentials and deserves at least the minimum degree of respect you demanded from me. You performed one experiment that I'm aware of, with a cockney accent! Thane's BITT transformer has been replicated by numerous respected people. Get off your throne!

I wound two helical coils, one monofilar and the other bifilar.

Coil parameters:

10 mm Ferrite core or air core, length 50 mm
length of coil former 50 mm
length of winding 42 mm
19 layers, ~160 turns each layer, ~3000 turns (~1500 bifilar)
monofilar: tap between layer 8 and 9
bifilar: tap between layer 10 and 11
paper between each layer
0.22 mm wire diameter

DC resistance 77 Ohm

inductance air core L = ~48.8 mH  (100 Hz)
inductance air core one wire of bifilar L = 12,2 mH (100 Hz)

inductance Ferrite core L = 357 mH  monofilar, L = 367 mH bifilar (100 Hz)
inductance Ferrite core one wire of bifilar L = 92,5 mH (100 Hz)

The monofilar coil is wound a bit tighter (more tension during winding) than  the bifilar coil, therefore the diameter of the bifilar coil is about 2 mm greater than the diameter of the monofilar coil (which seems to explain the ~3% higher induction of the bifilar coil with a Ferrite core)


I also made a 1:1 transformer for the function generator:

FERROXCUBE - CLI-ETD49 - CLIP
Farnell Order Code: 105778 (order 2 clips)

7 layers, ~16 turns, ~110 turns bifilar
0.8 mm wire diameter

DC resistance 0.4 Ohm
inductance 34.7 mH each of the two 110 turn wire windings

I will do some tests soon.

Greetings, Conrad

I measured the self resonance and the self capacitance of my new monofilar and bifilar coil (see photo and other parameters in my last post):

self resonance monofilar air core          101 KHz (harmonic square wave 33.7 KHz)
self resonance bifilar air core                9.3 KHz (harmonic square wave 3.1 KHz)

self resonance monofilar Ferrite core   38 KHz (harmonic square wave 12.8 KHz)
self resonance bifilar Ferrite core         3.35 KHz (harmonic square wave 1.1 KHz)

http://www.1728.org/resfreq.htm  (calculator: Hertz, MilliHenrys --> Farad)

self capacitance monofilar air core                    5 pF (scope probe 1 pF in series)
self capacitance monofilar Ferrite core              5 pF (scope probe 1 pF in series)

self capacitance bifilar air core              6 nF (scope probe 1 pF in series)
self capacitance bifilar Ferrite core        6 nF (scope probe 1 pF in series)


The difference in self resonance and self capacitance are big in these new coils (in comparison with the pan cake coils).

I attache all coil parameters as PDF-file.

Greetings, Conrad
