Joule Thief

@ Mk1

My toroid is not form gold mine ...

So its hard to comment .

You must have a very high permability toroid to get 1000 volts with only 140 turns. I can not think of any other explanation.

@all

I just got burned buy my jt twice , the second time was mo make sure i wasn't imagining things . Humm

@ Mark:

Sounds like an RF burn...your frequency must really be getting up there.  Be careful man.

Umm Hi everybody,
I was just watching the Lindemann movie again.

I have the patents downoaded and before I watch it again I will study them more closely since the movie is so blurry.(like my scope shots)

So, xee2 yes and no.
I am not wanting to force the direction from the secondary.
I want to use an inductor and ground one wire but there are 2 other wires or at least one more wire I need, I think.

So, I am thinking of splitting the 2 secondary wires like a Y.
Remember the amazing 1300 volts gadget got a while back? (yes, bill just mentioned it this morning) he did this by making 2 wires out of one side of the secondary..
That may be enough, or I may need another on the other side.

I had this interesting result 2 times. They are related but I am just starting to get how... from P Lindemann.
I most recently rediscovered that if I put a secondary wire in the middle of 3 leds (diodes- maybe I am forcing the direction) the lights are all much brighter and they do not effect the other array using the other secondary which is a separate loop on its own.
The picture for this is the most recent pic next door.

The other related one is that when I was playing with this part of the 2 tier (before I straightened the drawing out) I had the secondary in the middle place of 2 leds and I removed some wire and the leds stayed lit with only one wire.
I am sure these are related.
I have not been able to repeat this, although I did make a drawing at the time.


@Mark,
It may be that it is necessary to use a spark, but everything that P.Lindemann says can be done to some degree with the very sharp pulses we are getting with our joule thief pickups/secondaries.
I am hoping I just need to get the connections and probably the wire length right.

Ian middleton told me about the 1/4 wave last year. I don't think it will be too hard. The waves are pretty long and 5-8 feet is right in the place of 1/4 of something... I don't remember what, but I have a link and will return with this info in a bit.
EDIT
If the applet is right, 2 meters is 1/4 wavelength for around 38MHz. I think that is what the MK1 is since it starts with about 2 meters folded...etc right?

wow we are on!!

OK I will repost that drawing here since we are all here.

ha my job is much bigger than you can imagine .. 



hahahahaha... 

nice mark .. i was starting to wonder as i finished my last coil 20 turn x 12  and my results were poor ... 

like 175 v from a aa   so it is a turn thing ..   i had 120 turns ..  on the one i was getting  410 from 

it was a 10 to 1 turn ratio..   

btw

stew

i got some HEATER RINGS TO DEVOLOP ...    ILL JUST USE 1 OF MY HUNDREDS OF DESIGNS ...

I SAID PISS ON THE FLASH LIGHTS AS THE GUY BUGGED AND BUGGED ME  SO NOW ..  LOL 

he will have to devolop his own junk ... lol 

ist

ps mark ..  get a MICROWAVE DIODE.....

and for my next ring ill build mk1's hv unit .. on a 1" black ring to see what i get for results ..

It seems pretty obvious to me now....that torroid perm and flux make all the difference in output after seeing mk's results and mine on almost exact design.  I wonder how Hazens1 new torroides are working out???
