PUT THE BOTTLE DOWN CUZ .... you dont want to miss out .........


WHERES ALBERT HE SHOULD BE SHOWING UP SOON ..... 


BTW DID YOU CATCH MY OTHER EYE WINKING AT YOU ALL ....   

BOTH ONLINE NOW ......    ALSO FOR THOSE THAT FOLLOW MY GROWTH .... IM SHRE THERE IS A FEW ....  LOL   

I HAD TO GROW MY BRIAN FOR EXTRA STORAGE .....  LOL     

DO YOU KNOW WHY ..... ?

@Jim,

gary
Q2 = if you feed the output into a bigger transformer, from a smaller transformer, you will not get a hi output, swap the transformers around then you will get more.
BUT, take the different size windings into consideration, if you push too much through smaller transformer windings, then it will get warm, just keep an eye on it.

I guess this is the reason the fuji transformer on the lower tier is the big one with 1760 turns.
Thanks Jim, that is valuable info.

The circuit (w/ the 12v dc car lamp) is important information too, thank you.

@All, does anybody know the numbers of turns in the MOT? (I am wondering what should be expected from this.)

@Wilby,

I would like to add a little bit to what was said yesterday.

We examined our transformer numbers a while ago.
We all are getting much more than the regular transformer numbers would predict.  (Often the difference is 5 times more.)

The fuji AA first level transformer has 1760 turns on the secondary. (ref jesus drawings etc)
This is way more turns than any or our toroids need (thank the toroid?)

Here is a little example from my family of toroids  ...

It has a bifilar with a total of 22 turns on it. (evilmadscientist design)

Way back in January, I happened to notice that I could light a led from the single secondary wind around this. After some studies I learned that 4 turns was plenty bright, and I turned a secondary of 16 turns and lit 30 leds with a combination of series and parallel connections.

This uses volts from the series connections
and
amps from the parallel connections.

The normal transformer math on this does not really work.

For starters, the secondary is a step-down transformer no matter how you count the bifilar. (as 11T or as 22T) When the 1.2 voltage from the battery is figured, well...

The other part is the amps part.
The volts are being drawn from the battery to operate the transistor. At that voltage the transistor is able to provide the amps needed to light the lights.

So, in a 2N3904, the volts of .7v is needed and about 20-30mA should be needed for each light at full brightness.

Even as I have noted in my candles, when a super-bright led uses 5mA and is still quite bright,
the total mA used for 30 lights lit at that brightness should be a minimum of 150mA drawn from the battery.

And, this is simply not the case.
Not only that, we have even seen amps draw decrease with the addition of lights.

I don't know if any of these numbers surprises can be seen from a straight transformer. I know much of this is caused by the bifilar primary, and the bemf of the switching transistor.

If you would like to experiment with a few of yours, I would be very happy to see the results of your tests. They would sure be easier to wind.

Thank you again for bringing this up,

jeanna

@MK1,
About adding a magnet to a joule thief toroid...

My first joule thief, which I made in the winter of '07'08 was made on a toroid-shaped ferrite magnet. It worked, but not as well as some others, and after a week it gave out.

It seems, the magnet had done something to the silicon transistor, or to the doping, or something.

I reused that transistor just to be sure, and it worked fine, but I had to take it off the magnet and wait a while.

BTW, it was this experience which gave me the impression that the 3904 was not as good as the 2222. But what was really happening was something to do with the magnet.

I do not know if it is correct to say that the magnet had "saturated" the transistor, but it was a sort of saturation effect.

So, please keep a magnet stuck onto a toroid joule thief for a week or 2 and let us know if it changes your joule thief operation.

All information on this is very helpful.

thank you,

jeanna

there is a relationship between the materials .... 




a harmonic relationship ....

ist!

same as the earth and the SHOCK YA! ROCKS..

Thats right, you get more current out of a single layered coil.
The more single coils you put on, the lower the voltage you get back out of each coil.

perhaps I should have said, if one big secondary coil output is 256v, then you decide to replace it with 4 smaller coils, each of the smaller coils = 64v. each coil had 65 turns on it.

Well, thats how it worked out for me.

yes, you can view current behave like this.
but current depend on a few things.
a sure thing tho, you won't have more current then you can put in.

for AC/pulse DC you have the coil's impedance and coil's configuration.
for DC, you have the coil's resistance and coil's configuration
it can be multi layered but in that case you must use the proper method for windding it.
looping from start to end of the coil's form, go back to start whitout looping,
then loop to the end again.
repete this till you have no more wire left to wind.


yes, if 200 turns give you 100volts and you make it in 4 coils you will get 100 volts out of them.
but if you connect to only one of the 4 coils you won't measure 25 volts on it.
since the impedance of only one coil is smaller, the voltage you will measure will be higher.

@Xee2
To make the neon brighter

Raid the parlor, grab about 4 - 6 ft of alfoil and stick the "free" end to the sheet of alfoil, then lift the alfoil as high as you can in the aeither.

See if the neon gets brighter the higher you push up the alfoil.

you can also use capacitor(s), it is the same thing.
