Hi Mike,

Many thanks for your interesting results. However, may I kindly repeat my question on your method of measuring those DC input and output voltages and currents?  I mean whether you use two meters at the same time: one voltage and one current meter? 
For instance in your first post you wrote: "I started with 16 turns primary, 4 turns secondary which gave me 7vdc 12ma and 42ma draw from battery."   Here you meant the 7V was measured across your load when your load consumed 12mA? And the 42mA at the input was measured when your load was drawing the 12mA? 
The same question would go also to your measured data with your third coil tests you had referred to also in your first post here.
These measurements are important to clarify because this is the only way to avoid misunderstandings.

Regards,  Gyula

 
just thought i would post some interesting results,

i started fresh with  a different iron powder toroid.
i tuned this similar to the way described by Mk1 on page 306
but without a pickup coil and aiming for highest ma rather than volts

also, i wind the third winding with the same amount as turns as the primary,

16 turns primary  - 4 turns secondary
                            11vdc          15.9ma

third winding                                                     10uf cap from diode to emitter

16 turns               16.87vdc      22.34ma        without cap
                           11.59vdc      39.2ma          with cap

32 turns               23.6vdc        17.5ma          without cap
                           11.3vdc        38.1ma          with cap          at this point i also get  -> 4.12vac

48 turns               28.45vdc      17.26ma        without cap
                           10.75vdc      33.6ma          with cap                                               -> 5.7vdc

i will be adding more turns tonight to see what happens.

i found it interesting the more turns i added the lower the vdc i got and the higher the vac.
i am going to have to find an online store where i can buy some better toroids to try this on.

must go read the past days post now.

@all

I wish to say that my machine first lost internet connection, Then began saying when rebooted that the hard disk did not exist.
Then it began to sound a beep at regular intervals, after a while it began to sound a continuous beep and that was it for the machine.

It took me a long time to save the harddisk's information with another machine and to install another motherboard. I must mention here that for to get the internet working again was a real hard job. After I got the internet working I had to download the motherboard drivers and they were incomplete. The motherboard is a used motherboard I bougth long time ago on ebay.

I must now begin to read all the information that has been posted in all the threads I am following now and hope that my machine does not do the same thing again.

LIKE I SAID MANY TIMES 


this is my 7th computer..... 

this has cost me a great deal   not only the materials to build the hundreds of things i have .... the time ... 

but it dosent matter ......   i will keep at it

keon1

let me ask you    what will be when you charge a cap.........   does this increase your AMPARAGE?!?!?!?!?!?!?

now

lets say i have 30 feeds ....  from 2 dead aa batteries ....  now what will be if i put 30 cam caps on my output ....  then i used a switching device to systematically drain them .... but at a speed that THEY ARE ALWAYS FULLLLLLLLLLL   HUMMMMMMMM

or if SOMEONE CAN EXPLAIN HOW AND WHY CAPS SELF DRAIN.....

AND WHAT CAPS WOULD BE THE BEST SUTIED FOR THIS .....   I WOULD EXPECT THE LITTLE GREEN CAPS WILL WORK FINE FOR THIS

the ones you find in a cfl driver.....

now also take note to MY OUTPUT FREQ......   LETS SAY I PUT IN TO MY COIL ... 1KHZ @1V 

AND IM RETURNED 52KHZ @110VDC ...   EVEN  IF THE OUTPUT WAS ONLY 2 MILIAMPS TO LIGHT A NEON  ....  CUZ THE HIGH SPEED THERE IS AN INCREASE .............................................

PLUS X 4 OUTPUTS....   so what porpus does the cap serve.....  does it transform the high freq to pure dc?!?!?!?!?!?!

if it does then ..... 

LOL

we shall see.... 

IST!!

the way i see it ..........

i should be able to isolate the source compleatly from the out put except for the use of the input engery to make a magnetic feild ...

to do this you want to be able to light leds  from your secondaries ... and the jt led should stay on.........    i was able to do this ... 

once this is achieved ...  we then will need 2 secondaries .... for 1 full wave bridge rectifer ....  and the leds should stay in place so you DONT PULL FROM THE BATTERY ON THE SECONDARIES... 

YOU WILL PULL YOUR NEG FROM THE BATTERY FOR THE JT FLYBACK LED... ...   BUT YOUR SECONDARIES ARE COMPLEATLY IDENPENDENT OF THE SOURCE ......   IF YOU USED THIS   ANY OTHER WAY IT WILL ACT AS A TRANSFORMER FROM THE SOURCE ON THE OFF CYCLE ...   THERE IS NOTHING WRONG WITH THIS BUT IT WILL DRAIN BATTERIES ...

I DONT WANT TRANSFORMER ACTION ....  I WANT THE FREEEEEEEEE STUFFFFFFFF

[innovation_station]

so i guess it is time to look inside the toroide.... 

what happins on a micro scale ...

the electrons are converted to magnetics in the jt coils ...  180 deg from 1 another ... ok  so the first coil gets it power  the second is choked down .... so it flows slower through the windings ...   

so in the toroide it flows both ways...   neg and pos or n and s  but as the first feild traveles around the ring in magnetic form ...it slams in to the choked coils traveling magnetic feild ....   they cross....   and then is intrupted .... the colapse then happins ...

so it is a timeing thing ... hence varing the restance of the second coil....  changeing the freq.... 

when the colaps takes place ... it back flows out ..... to all that is there .....

then we rectify it cuz it is actually cold electricty

the rectifier   is a flipper ...     cold to hot!!!!    hummmmm   

and caps love cold juce....     

they are TRANSLATING DEVICES    SO IS A BATTERY BUT AT A COST.......




ill save the rest for the next 400 pages ..... lol 

ist!

THIS IS A        BUILD IT...  SHOW IT ....  EXPLAIN IT .... SHOW        THEY USED TO CALL THIS SHOW N TELL.....

lol       DID YOU LIKE THE IST COMEDY/REALITY  ACT     

DATA BOOM!!   LOL

added a few pics of mk2 6pac

Thanks for the tip, but i had already gone through that.
look like it is a chipset ic that is at fault.


@Pirate88179
great idea you had there with the schematic tread.
know that it have already helped someone, me. 

TheNop:

Thank you, I appreciate knowing it has helped.

@ Jesus:

Sorry to hear about computer problems.  Seems like there is a lot of that going around.  Best of luck to you with it, I know it can be very hard sometimes.

@ IST:

I think your theory went over my head.  I am going to have to go back and re read it.  Thanks for posting it.
