Joule Thief

[jeanna]

Hi everyone,
I am interrupting a test to report this.
It is about adding a cap across the base resistor and looking at the voltage drop way way down.

I am getting better and better at understanding what I am seeing on my scope so I understand this better and here is what my scope is showing for the difference without a cap and with a cap.

with all the usual and no led, just the bjt without led
_~~~~~~~~|_~~~~~~~||_~~~~~~~~|_~~
the scope reads this and reports 65volts. but the little wave at the bottom is around 6 or 7 volts. see below:

now with the cap and still no light

_|^{`~~</sup>|_|<sup>`~~}|_|^{`~~</sup>|_|<sup>`~~}|_

the scope reads this and reports 7.7 volts.
It seems the cap can see and smooth out the spikes and incorporate them in the wave. And the scope calls it voltage and shows it. I know the folks with schooling in EE and folks who own scopes know this, but I want to verify it and make this little php drawing for the rest of you. Now back to the kitchenlab!

MK1 that is a nice explanation. carry on with that please. I am beginning to understand a little.

Hi everyone,

Gary was able to email this to me. it is his

Hi everyone,

Gary was able to email this to me. it is his
LM1 lighting his  Array

from gary

Thanks  Jeanna


This LM 1   was made  with  a  spool  of  radio shack red wire .    300ft  #30 magnet wire
I simply  sanded the enamel off the ends  and added a primary   (8 turns )

No  toroid ......although  a 1 inch  toroid  can fit into the  center of the spool to raise the  permeability 

The  LED array is   out of a LED floodlight  that  is designed to  replace a 45 watt  floodlight .     It has  60 LEDs
I measured  working voltage of this array  when I first got it .
It  was running  at   83 V   
In the  picture  if I remember right it was running around 40 V 
With no  load  the  voltage of  this   coil was  about 250V

here  is a little theory that I have  been  working on for a while








Infinite  power  VS  greedy power.


Nature is  never greedy .
Nature it always infinite.

Power  is part of nature ......therefor it  is infinite.
We have been taught only how to be greedy  about power.
We  have been taught this so that the  greedy  can  keep profiting   by our use of  their power.

How  does infinite  power work ?
Just look  around you .
Take  the sun for  example .......the energy it radiates is innfinite  for all practical purposes.
All that  energy   goes out into space and  it heats what ever  it   comes in contact with .
This  energy heats anything that  it comes in contact with without effort  ...... without  draining  the sun

If   we had  unlimited  technology  and   tried to be greedy   about the suns energy and  tried to extract  all of that  energy from the sun itself .......what do you think the result  would  be?
It seems to me that the act of   taking all  the energy would   put an end to the sun  very  quickly /

Same thing with a  flame .
If  we  try to  extract all the heat  from  the  flame  itself ......the flame  goes out .
If  we  capture the heat a little  distance from the flame  we can  have  heat for  a much  greater time .

With  a  transformer ........ we  create  a magnetic " flame "    this   magnetic  field   affects   everything around  it .     
If    we   try to tap this  magnetic  field   right  where  it is  created   we can  only   get out  what  happens to be there at that moment .
We   put out the flame  by taking   away  the heat .
If  we back off a bit ........ loosly  couple  the  pickup coil   we can  collect  energy  without  putting out the  flame .
I believe that this is what  Jeanna  and others have been doing   when they light lots of LEDs  from  secondarys . These  secondarys  are  partly  isolated   from the  magnetic field  ( the flame ) 
Isolating   the  secondarys  even more  should   produce  an  output  with even less  draw  from the  souce .

We have been taught for many years that taking the energy right from the source is the only way that is possible .
We have been  taught  that   for economic  reasons ......in other words greed .

It IS easier   to tap the energy right at the source ..........but it  is  also foolish .
WHY should  we kill the energy   just to use it ?
We have to remember this  every step of the way .
It  should be possible to  extract  energy  in a string  on pickups . ...........IF  we are not greedy .
If we try to take to much  at any  given point .....the  whole system colapses and we gt nothing .
To  use  infinite energy always protect  the source ......always protect  the flame .......at every step  of the way .

MK1 that is a nice explanation. carry on with that please. I am beginning to understand a little.

In my previous explanation i think i have reversed the poles. Edit not really since the field and the coil opposed .

Now that is a one coil setup but think with 2 or 3 coils , try to see the field direction and see attracting field or repulsing one.
