Joule Thief

[altrez]

So, Altrez,

Have you ever put these multiple pickups together in a parallel connection to see what the scope says?

I sure would like to know before you achieve full battery charging what the scope tells you that each coil has for frequency and volts and if you put them together in series- I think that is the one you did?- and in parallel - again frequency and volts.

I realize it means taking some connections apart, but I sure would like to know.

thanks,

jeanna

I will get that information for you this weekend jeanna. I will also get some readings with my LHR meter for the coils.

Hows things going on your end?

@Bill,
Ohh, but you have already have done something remarkable, in fact several.
This forum testifies to that itself.

@ Jim:

Thank you.  I swear, if you had one of these big supercaps, there is no telling what you could run down there.  I believe credit should always be given where it is due.  Anything I have been able to accomplish here is only due to the help and ideas of others.  Soon, hopefully, I will come up with something totally original but even then, it will be because of what I have been able to learn here.

Now, on to the EB-Monstercap-JT experiments.

Bill, you have introduced me and others here to the Joule Thief, your Earth Batteries, the Super Capacitor, and thats for starts, the first time I ever saw a LED powered by the earth was from your setup, and I was hooked, line and sinker.

Yep, I could do with one of those new fangled hoodickie wach-a-ma-callits 650SC.

Just  don't  give up .
Keep playing with it  .
It  worked  for me .....so there is something  there .

Have you  tried going back to the start ?
Building it   one piece at a time ....... and  checking   how it is  working  after  each piece

``````````````````````````````
My  charger actually lost  a little  voltage   today
I checked the  wires  and  found  a couple of mistakes . ......it is a wonder that it charged at all 
I  think I got  it fixed .........now I have to let it run for a while and find out if  it keeps charging  or  poops  out again

Thank you @resonanceman !
How it has been going?

I will build a new toroid coil and start from step one.

@Altrez,
I suddenly got it, the penny dropped.
 
OK, this is what is going on, the reason why the JT can charge the single battery, and it is so simple.

The fully charged 1.5v cell when connected is just like a starter motor, it cranks up the Joule Thief, then the Joule Thief begins to run, when it is fine tuned, the Joule Thief, becomes like a Battery (but physically it isn't, only energy wise), it takes the place of the 1st battery, because it has a higher energy output, so the real battery becomes the recharge battery to soak up the overflow of energy from the Joule Thief.

If the Joule Thief cannot achieve more voltage and current, that the Battery is putting into it, then this will not occur, it willl just be a standard Joule Thief.

To see if your Joule Thief can be a OU device, place a capacitor of about 10uf at 6.3v DC accross the 1.5v Battery, start the Joule Thief, then remove the Battery, if the Joule Thief continues to run, without the Battery, you can then say it is a successful test.
 
Did that make sense? this is why extra LEDs can be made to light at the same time.

As I understand   it there is more  going on here .

I beleive that  the basic JT is mostly making  flyback pulses .
It makes a pulse .......and then shuts down for a second ......the  pulse ends  at the battery ........where  it is either used  to charge the battery or used before  it charges the battery for another pulse .
REMEMBER the battery is a CHEMICAL possess .....it takes  a specific  time for the charge or discharge to occur .
I have tried several times to  switch to a cap while  running  a JT that was  charging the battery  .    I have not got it to work so far .

What I am seeing with my self  charging  JT is that to charge the same battery  the JT must be running very slow ....... the battery being a chemical process  can not  charge and discharge at the same time ......so  you have to give it enough time to do one then the  other .
I don't  have the  equipment to find exact numbers  but   a ballpark  number is  2 flashes a second may be about max for  charging and discharging the same  battery at least that is about where it seems to  die out for me .


That seems to be the reason that  I can't  just   leave   my  charger JT alone  and  let it run ........as  it charges the   frequency  rises .......and eventually it stops  charging .




As far as running lots of LEDs off of  different  secondarys  .....I think that is  a whole  different  ball game .
Current  teaching  is something like  if you have a transformer  with 2 equal secondarys  the  current from the input  will be divided between those secondarys  .......end of story . ( edit .... for the skeptics ....... I  know  that there are losses such as eddy  currents  in any transformer ....  we are not talking about losses here .  )

In real life it is not quite that simple .
I believe that ALL the electrons  in ALL the  atoms near  the  primary  are affected ........      A MRI makes  images  of living  tissue  by affecting the  atoms  to change spin then  mapping  how long it takes them to return to normal .      If  the magnetic field   of the MRI is  affecting  the  spin of ALL the atoms .......wouldn't  a smaller  magnetic field  do the same thing  on a smaller scale ?
I have some theorys  that I don;t  have time to try to explain now .......but I  believe that    the people  that have driven LOTS of  LEDs   with secondarys  are  just tapping into  a larger  section  of  this  electron movement .

@Altrez
Well done sir.

Jim,

I normally always have a cap in that spot already its just really small so I did as you asked. And well it sorta worked! This is how it went.

With the Cap in place I pulled the main battery I was still producing .003 mV with out the battery! With the battery however its over 200mV. The Cap would produce .002 to .004 recdified DC voltage.

The way I test is to attach a meter to one of the Bridge rectifiers. And watch the voltage. Its a heck of a lot lower with the cap but it is a constant with the same sort of voltage spikes.

I am not sure if this is making any sense but like I said it sorta works. There is a lot of EMF floating around here in my kitchen so it is more then likely that the cap is simply picking that up. And with out REAL voltage being produced from the cap 2 volts or more. This test can only be labeled as inconclusive.

I did find out however that if I leave the big cap hooked up with the main battery and a blocking diode It will charge the cap up to the spiked voltage I am seeing on my setup. And that I find very cool.

So this is what I did next. I put the big cap back in place with battery. And let it catch the spikes. It charged up to over 550mV. I took the cap out and tested again and it was true the cap was charged to 550mv.

So why does that excite me you might ask? Well that proves to me at least that the main battery is catching an extra charge from the "back EMF???" toroid somehow. 

-Altrez

If you can find a capacitor with a volt rating which is closer to 2 volt, I think you will have a better result as the JT output wont be struggling to keep it topped up while the battery is out of the circuit.

This was my theory on why a single battery could be recharged, and you have proved it with your experiment, well done Altrez.

Goodnight all, I am tired
I'm hitting the sack.
