I am looking  forward to  seeing  how this  works out .


Do  you have any links  or anything  on  stuff along this line ?
What you  were talking about  sounds kind of like a project  I have been thinking  about for  a while .

After  thinking about it for  a while  .......I decided  to  tell you   about my  ideas  about  what  you seem to be   doing .

I had  this idea  close to 8 years ago .... I am not sure I am  much closer to getting it buillt than  I was  then .

I can see  how   it works .......but I am not  very good at  building.

Just  to be clear  I am   adding a picture  of the coil  I am talking  about .

My  original  came to me when I was  thinking of making  a Tesla coil .
I was  looking into  making a spark gap .
I did not like what  I saw .
All the  larger  Tesla coils  used  a motorized  spark gap  for  faster quenching.
I read that when  a Tesla coil is  working  well   you should hear  an UNEAVEN  sound .

This  stuff it all  wrong ............but it is the way all the  Tesla coil  sites are doing things.

A Tesla  coil  requires  that the  primary  be tuned to a specific  frequency and the   secondary  be tuned to  a harmonic  of that   frequency .

A spark  gap  in a Tesla  coil is a   way to  make  the energy  transfer  between  coils in short  bursts .
It  also makes sure    you have a very high  rate of change .

If  the speed of  a  motorized   spark gap is not timed  with  the   harmonics  of the  primary and secondary     you may have  a coil  that makes big  sparks ........but it is not really  a Tesla  coil ........because  a Tesla  coil is  about  resonance.



OK .... I will  get off my soapbox   






If   a   specific  core   was added  to the inside of the   coil  pictured ......  It could  work as  a spark gap .
It would also be very similar to a Mag Amp.

The  whole thing would have to  be  carefully  built .
At low power   it would   act as a normal  coil .
The flux from the  coil will  flow though the core .
At  some power level ......  the core will  go into saturation.
After  saturation    the core will no longer   hold  all the flux ............
Then    .....BANG ........ it   jumps to  the next level .

A  thicker  core  or higher  permeability  core  will  raise the  power level  required for the  jump .
Unfortunately the  coil  will only work  at  one specific  power level .
Adjusting the  number  of windings may be  a way of  partly  adjusting   the  coil for  different power  levels ........but in general  the core  itself  will  set the power level .
An  air core could  be used   for low  power .....  but I am pretty sure that the bang comes from  storing   flux  in the  core .

The  space  between  the  core and the secondary   will  be important .
Without  the space  the    flux may jump  to soon ........ To much  and   it will be hard to  pick up  much  charge .

IN theory ........ if  a thin  core  with a winding   inside of it    was placed in  the space  between   the   primary  core and the secondary .
A signal   applied to this   winding  would  attract  or repel the flux in the core ..
We  would have  an inductive  triode.
Also ........  if the  grid coil  was  powered by  a steady  current  it should  make the  coil  act   like a  rectifier .


So far  I have not   got  results that  I am happy  with ........but  in a couple of tests I did  end up  with  a coil that also  worked  as a voltage divider .
The voltage  applied  would stay in the  original  coil  up to a certian  voltage .......above that  voltage would  show up in the secondary .
This  alone   could  be worth developing ......it could  be used as  over voltage protection  for  some of  our circuits .

well gary do hang round thease parts ..  as im only working on overunity.com no where else on the net ..

but as soon as i get moved .....    

we all gonna get moved ... 

lol

so i will be building fully this unit public on overunity ...  along with all my other half finished units ...

i left them behind not because they dont work ..     i never compleated much of my work .. yet ..

not at all cuz it does not work ...  but the time to build them compleatly was not right ... 

the time to finish ALL OF MY WORK HAS COME !! 

and each and everyone is welcome to join in ...

would really like to have an expo next summer at the beach ...   but i dont want to be the only one there .....

peace

w

still moveing ..... 

gary sir you never cease to amaze me .... !!

im glad your here ... and 8 years ago AWESOME.

i call this my work but HONESTLY ITS EVERYONES WORK 

AS I GAVE ALL MY WORK  FOR PUBLIC USE ..

I have like 30 diffrent ways to build that coil

how bout garden wire ...  bailing wire ...    hummmmm

i would wind it on a 4 rib unit and rectify the garden wire or send that to the NEO ZAP..   i got an old movie some where on ou of this or a varient of it ...

lots of ways

another you could try is the MAC trick ...     alum 1 turn  based on surface area rectify it ... 

another key to this coil showen is pnp switching and diode blocking it from returning to the switch so it colpases in the EATHER  and when it DOES CUZ IT WILL it charges up near by metal objects so be wize ...  ya know door handles tools ....  that kind of thing ....  IM NOT JOKEING .....

agin when im done the shift!!!   then i will build picture and video lots of TOYS...

Hi,
sorry, I did not yet read all the latest posting, have to catch up soon.

Great work in this thread !

I just was in a "Building-Shopping-Mall" the other day and
saw these new higher power LEDs that now have a very
comfortable warm white light, almost as warm as halogen lamps.

Maybe some of you can get some and post some
videos how you light up these LED bulbs.
The light is very nice for the eye..
Not anymore the cold white, but warm white light.

Here I found some on Amazon:

http://www.amazon.com/Brightest-MR16-3x1-5-LED-White/dp/B001GV22Q2?tag=ruhleben-20

http://www.amazon.com/Surface-Mount-White-Light-Module/dp/B001GH0FE2?tag=ruhleben-20

and here is a video which shows the difference between cold white and
warm white LEDs:

Hope this helps.

Maybe someone will find a way to run them off an earth battery
with such a brightness ?

Good luck.

@all

I conducted a test to see why i can light led in both polarity from my secondary.

Ok first the mk1 split jt coil , will light both way regardless of the secondary design , meaning going one way or up and down.

Now when i tested my scalar jt, i get a strong voltage in only one direction , lighting a led in only on direction.

So i made a up and down secondary (pickup coil) regular mk pickup coil , and got the leds working both ways .

Conclusion the mk1 design is really design for dual polarity work , from the plit jt and the up and down secondary.


I find this so cool since it works exactly how i imagined it...


Mark

Btw , my scalar jt has 16 turn bifillar jt coil and i got 50 volt from a 21 turn up down pickup coil, and that is on a toroid i considered bad.

Here are 2 videos to see how the LED future will be,
if the prices still come down:
