Joule Thief

Hi all

I made further test with my air core coil JT, and i need your help.

Here under i enclosed the last shematic in comparison with Xee2 last one.

By accident i separeted the primary (5 turns) coil from the 60 turns secondary and i got better results on my neon bulb.

So i made different test and i could decrease the resistor down from 470 k to 2.2 k. Than i could reuse the 2N222 a transistor.

Than i could tune the lightness of the bulb by separating more or less the primary coil  Amazing !

But my great question to you is HOW DOES IT WORK with the neon bulb connected to a very small antenna and it lights very brightly ?

And how is it possible to get scope trace without the crocodile probe connected to anything ?

Excuse me to be ignorant but i have always understood that there must be a path for the current to go back to source  and it seems not to be the case here ?

I enclose here some pix

1  shematic with modif

2 small loop antenna (red wire) and scope probe installement

3 Coils separation for tuning (notice the distance with the spacer)

4 scope trace of the scope only (without neon connected)  p to p voltage at 366 volts

5 scope trace with neon connected

What's happenning here ?

Thanks

Nice going Woopy

If your using more than 3v try disconnecting the resistor from the transistor base after it's started.
It should keep running and lower the current intake quite a bit.

Your neon lights from the small antenna your using.
It exites the environment around it and the energy comes in from both ways.
You should be able to light the neon by holding one lead of the neon and hold it up by the coil.

I'm not sure if you seem my last video but it will light a big flicker light thats like a neon and FL tubes with no wires.

Here is the video if you havent seen it.

Also a bigger coil will work better for you.
Mine the L1 coil is 4.80 mH and the L2 coil is 5 uH.

And how is it possible to get scope trace without the crocodile probe connected to anything ?

There is a connection through the air by capacitive coupling between two wires that are acting as plates of a capacitor. At these frequencies power can be transferred through very small capacitance values.

Have you tried using less than 5 turns on your primary coil instead of moving it away?

here is 1 for ya .. 


whats going on here ...  ??   i charge a cam flash it blinkes a neon ....  yay!  i take the battery out of it ...... 

the neon still blinks...  how?  why ?   i pulse the god damm thing it speeds up ...  why ? how?

i take a  feed out to a supercap it charges it ...  how?  why?  i then feed back the god damm thing .. it is now self running how god damm hard is it humans ?

why how why how.   

go to school .. 

i got my grade 10   rickey!

W 

wont be long we will be sueing many !!

all the little #UCKERS  that stole my work ... 

THE LONGER I SIT NOT BEING PAYED FOR MY WORK THE BIGGER I BITE YOU ALL !

; )  WATCH ..

ever see a pissed off god ?

sometimes ...  i think it is best i destory my creations .. 

this is one of those times ..

too bad i had hope for humans .. i fought her 13 years ..

1 reason i did what i have the dream to have a life ... and spend the time with my children  wich i see bout 4 times a year on avarge ..  the fucking gov took them away ...  so fuck em !

i got the worlds biggest gun ! 

but they all stole ...   so i burn em all

first i burn your wallet out of your pocket ... 

next ...    well thats your call !

W

the choises i make dirrectly effect this entire planet!  no body wanted to market a stupid simple goddam flash light and pay me ...  so  ..  now i guess you will not use my work to benifit yourself .. as i will sue and win hands down ! 

it will be settled b4 it goes to court! 

: )

how long is my list ?

?

1800  pattends ...  yikes ..
