Joule Thief

[sparks]

    Transistors have a certain amount of capacitance.  When this capacitance is matched to the inductance of the torroid a series resonant circuit is produced.  Voltage can move through a circuit without current.  The current will be impeded by the inductance of the torroidal primary winding while the voltage will not. Voltage has said to have lead the current.  The voltage now resides in the capacitor independent of the current flow through the inductance.  The inductor mass has resisted current while it was unable to resist voltage. Take a piezo buzzer and feed it through a highimpedance transformer secondary.  The buzzer will not sound.  Now parallel connect a capacitor across the transformer or the piezo.  The buzzer will sound.

i have a winding style .. i showed a few years ago now ... at least a year and a half ..

anyhow im gonna rewind that today in a torrous form

it is a torrous pancake lapped and layored about a copper core ...

my jt coils in core  wound similar ... are vhf and then some ... lol

ist

oh yea bifillar speeker wire ... im a gonna TUNE THE MASS it might be a big coil ... we will see

my COLLECTOR  is 10 ' 8ga 1000v rated .. 90a   233.3 grams for colector coil  control will be the same x 2

i will see how it goes ...  7" loop 5 turn collector  it will be 16 ga speeker wire looks like i need 68.61 feet of bifillar copper speeker .. wire .. yikes ..  im a be busy ..

each strand is = mass to collector collector is cold return from fly back of jt .. control is the jt .... hummmm

a pump?


in all this thinking ... i got an even BETTER  winding configuration .... and i dont want to talk about it .... lol  naw i kidding ...  i do have a better config yet ... ill just have  TO BUILD EM ALL  ...

Suggestion for how to compare bulb brightness. Put bulb vertically on magazine or newspaper and take photo in dark room. The area lit up gives an indication of brightness.

a better way would be to lay the bifillar speeker wire sidways as you wind it so it pushes aginst the next layor ..

ya know... lol the last layer of the pancake pushes the next .. then the following lap layed on top that .. continue laps till wire is used ..

ill build and take picures ...

w815  you could split it about 2 cores ... and get a spin seperator ... if i choose to build it as such....

and then recombine it across the room on 9 .. lol    yes ... why couldnt i ?  im trying to find the answer why all of this is IMPOSIBLE ..  lol  i have not found an answer why this can not be done ..........

if anyone should TRY ANYTHING  im sedjusting ... i reccomend you think long and hard ... AND KEEP YOUR DAMM HANDS BACK... 

try a non liveing thing first ....  not ... your self!!  AND I DO MEAN THAT!

you were born in a month ...  and concieved 9 months prior ... what stone must you have .... ?

w

first pic materials
second  the collector coil
3rd tuned mass to mass collector to control

[innovation_station]

how about the 369 ac unit....

how about 2 pancakes .. and a feroite core .. reconnect happins on 9 in the collector coil.. 

i have 1000 ways to the same .. answer

hummmm

w

so gadget ...  how long can the jt can power box run 2.6vdc  down to .5v drawing 2 amp .. ?  how long will 1 charge of a cap last drawing 2vdc 2amp?  is better worded

here is a picture of the first layer in this simple style
