Joule Thief

[rensseak]

@ rensseak

I have no experience with them. Do you have a part number to recommend?

EDIT: Seems like good idea. But, I am suspicious about semiconductor being able to take repeated sparks. They may only work a limited number of times. The data sheets do not address this.

best is, just google for TVS-Diode

i dont know how it will behave in fast switching circuit and even the gas discharge tubes you are useing is not designed for what you will use it.

what a mess they make the rockets....  FOOLS ... LOL

WHY NOT  CHARGE A CAP AND DUMP IT AND BLAST OFF LIKE ALI SAID YEARS AGO NOW ....

LOL

KINDA LIKE A RAIL GUN ... LOL

BUT NO WE WOULD RATHER DESTORY THE PLANNET ... WITH THE EXAUST FROM THOSE JUNK TOYS...

but lets keep the real smart ones poor too... 

that way it will never go any where right !! 

lol WRONG 

ANYONE BUILD MY SELF RUNNING RINGGGGGGGG YET 

IST!

WELL ILL KEEP AT IT PUBLIC UNTIL I GET FUNDED     TRY ME

so i have 2 surface mount 3.6 v nicad rechargeables from the shake flash lights i got the db107`s from

i will put both 3.6v 40mah batteries off the super cap .. i could then use the voltage divider ..  and drop it to 1.2 x 3 feeds at 80 mha to recharge the aaa 300mah solar battery ..  or i could take the output of the 3.6 v batteries and feed the curcuit as showen

start from a aa charge a aaa for 20 seconds  remove the aa or the STARTER  allow the ring to run on the aaa 300mah till you have enough in RESERVE to allow the ring to run on its own ...

and if it will not run i have 9 more outputs i could use a few more as feedback ... or i could put the aa STARTER  on a 1 min pulser ... 

like i said if i had super caps ....  LOOK OUT! 

ist

btw i changed my feedback winding config to grab from both sides of the jt    lol

i decided to REDO  my curcuit on a bigger board ...  so every connection and wire can bee seen and traced with ease ...

but i had to take apart an older unit for the board  to build it on ...  so thats where i go today ...

ill mount all rechargeable batteries on the board .. recovery and driveing jt voltage devider ... the whole story ..

BTW, I believe you may be the very first person in the world, who has ever seen the output of a stubblefield coil on a scope, when Nathan was alive, there was no scopes. Lucky you.

Thanks Jim,
I had forgotten about that file.
Now there are 3 ways to read a NS generator with a scope.

I have used my NSgenerator as a joule thief and read off its secondary.

I have connected my NS gen to the ground and read through the tens which were to be left alone(, and I always thought he had a spark gap there, but could never prove it).

And the other day, I have connected my NS generator to nothing but Radiant waves being produced by the joule thief. I read those from the secondary too.

It is way too hot today to hook up the antenna to my geodesic dome frame. It is all galvanized pipes and stands 12 feet tall. It should be safe enough but it should have enough mass going on to bring in something. So, when this heat wave passes I will add a copper wire to my NS gen and see.

I am curious to see if this is a good landed receiver.
Since it is a good radiant receiver, it may also be a good radiant sender.

But the little joule thief circuit seems to be a very good sender.
Remember, he always seemed to use them in pairs. I think this is part of the plan.

_= wire maybe acting like antenna.

There is at least one pic of the above configuration.

I plan to do something like this, trouble is all my coils are different and I bet they need to be the same. So, for now, I will use a scope to probe for answers.

Thank you,

jeanna

@all

i ran across a link that I have never seen before. Someone might of posted it already. Its http://jnaudin.free.fr/html/overtep.htm It looks like a JT sorta. Its listed as a simple way to prove OU and also has some scope shots.

That is very cool, I have never seen that before.  That is our own Stefan Hartman, owner/moderator of the OU forum. (In case you didn't know)

Those scope shots do look familiar.
