Great video, 5 stars!

This opens up a lot more possibilities for us I believe.

I can't wait for my large toroids to arrive.

Hi stprue.

That is a very clear video.
Great going!

I was reading about dimmer switches last week, and
I was fascinated to read that the more modern less heating kinds are designed to alter the angles of 2 inductively coupled toroids to each other.
It looks to me as though this is what you are doing.
Since you are putting the juice into the system through one and changing distance etc of the coupled toroid, then rectifying it into the jtc.

I do not know if this is true, but also since it only works at or above the 2AA voltage level I wonder?

thank you,

When you tune it to it's resonances (coils that is) it can go as low as 1.2 volts.  I make vid's quick so nothing is ever fine tuned!  Pirate  this is just the beginning..with Dr. Stifflers stuff and our stuff we have a lot of things to learn.

you kno this resonance is not all of it ...  sheesh

here is another simple  design ...  i guess i will build this too

i just wish you would understand what im say in

it is just like a pulse motor ...  lol

then you spinn so fast that it feels gyro ...  but it is only twisting super high speed ..

then use that to control collector ..  it does not need to be bifillar ... can be air core

ill build it ... so you can see what i mean ..  and as  well i have pancake designs too

ill build a few more coils ... and show what i mean ...  pulse coil and trigger coil colpase to collector ... 

w

here is a pic of the required materials for this build ...  should be a great 12vdc unit ..
6" pvc sch40 core ... same white #8awg 1000v 90 amp collector .. then i have a spool of 1000 feet solid 12 awg 600v so  im not even sure the mass thing matters so much in thease designs ... as how they are designed .. but they will take some playing to get ripping great but thats the fun in it ..

soi changed my mind ...  im useing 28 gage wire 8 coils 29.1 grams each all wound same dirrection around ring ... i will wind 1 trigger coil ..   i will build 1 useing 12 gage too as it is less work and can handle much higher voltage ... this one im building will run from a aa no prob .. and it will have some high inductance i would think ...  223.3 grams of 28 gage as primary pulse coil ..

@all

Jadaro ,helmholtz coil , we could make jt core coil out of copper like you did,
i made one a while back worked great .
Now what would happen if we made a second core coil like helmholtz coil , but the second one with a tank circuit on it , matched to the jt freq.

I've done this, with the prefab inductors, it's not the best results, but, a custome build would be a better option.  I think that finer wire could be used for the voltage gain.  Also, making the secondary the same size as the coil to collector would be a wise option..  the coil to base could be small, insignificant even, as it's the current which switches on the base? ( yes / no ).

Anyway, the coil to base could be placed somewhere in the coil to collector and the secondary could be placed in-line.

I've just acquired an old pc monitor - it's huge, i'm hoping it has a decent transformer in it.
