im on it however my cam boards are not fugi ...  but they are what i have been useing all along and are a decent sized transformer ...

i would expect the same or similar results... 

we shall all see 

cant wate to build my plastic ring ...  ya know .... i put the rest on hold 

ist!

but this will be a great power supply 

kinda need that first ... ya know

@all

Some tough on the future, The limit are our imagination , find other uses for that power, we got light and power to generate rotation great for generating more power,but we need to think about other application that's the creative part.

At some point we will need to regulate the out coils power to 60 cycle to use on other application.

There have been many different technology used in the last 200 years , all have limitations , that is part of the fun, its a puzzle , find a way to use all of them together for there best application, we will be surprised of the outcome.

Also the time factor, cycles needed to get certain flow needed for good load application some sense need to be made there.

A voltage doubler or get the hv down ? Do we really get the the same amps in as out if we take the hv back down to 1.5V ? Time ?

Could we built a 1.5 v to 12 volt variable transformer , to kill dead bat around the house when they are no longer at spec voltage?

@gadgetmail

you keep working on what you got . Ok ?

Oh good. OK 

@jesus,I am sure many folks out there, way more than we know, are studying your drawings. You are clear and your captions are right there and...

But the REAL BIG value comes from the discussion that happens when you are unsure or when the 'designer' is making a correction. This draws attention to the point of importance and makes it very clear. So, please continue with this extra contribution. It is very valuable.

And so, in that light, I would ask you to change 2 things, if you would.
Please correct the 680pF to 68pF on those base caps.

The other thing I think is because there is a pictorial element to your schematics, the secondary is actually going through the center of the toroid, but the drawing shows it going around the whole thing. I tried it the other day, and I cannot honestly remember what the results were so I will do it again later, but the thing is that it is going through the center right now and in all the results posted so far. So, please would you make this change too?

EDIT: In fact you get nothing by wrapping the secondary around the outside across the center but not looping through it. I just did it with 3 wraps and there was not even a flicker.

Thank you,

jeanna

@All
@ thanks but DON'T STOP DOING WHAT YOU ARE DOING  because of my work . . We need the test you are doing Jeanna .on the Jt . I just helped get the current down . Continue on .

Looking at the Fugi it looks like there is a heavier  gauge wire wrapped around the transformer about 10 or 11 turns // I want to get a toroid to do what that transformer Does  and do it with a JT . Then I want to Help Mk1 and IST on the mag amp cause what i see is it needs a pure dc source like a fugi charged cap circuit maybe  and an ac source like a Darlington circuit  JT  maybe .. .. Ramblings of a Mad Scientist   Maybe ?


Naw ...  I'm gone for a while to eat and take My Meds

@ jeanna 

If you are still trying to make a low current JT I suggest you try the 2N2222A transistor snd make a toroid with 10 and 40 turns.
