Joule Thief

[altrez]

@all

I have a made new circuit called a "Bucking Joule Thief". I took a 3" in diameter toroid and placed two JTs across from each other using the same toroid. I then added at 90 degree angles two pickup coils with ac-dc rectifiers and caps with blocking diodes on each. I manually turned on one jt then the other. I did this 12 times. The caps on the pickup coils grabbed a slight charge "3volts" and the JTs did not seem to drop in voltage.

This is very easy to test.  You can see that effect. So if you think about it. If you grab the back emf. and then also have useful work "Charge caps" its a really cool effect

Its a bucking effect playing off two different back emf fields. Interesting to say the least.

Hello anyone !!!!

Please will someone answer me...

Has anyone been able to make a Joule thief powering either LED's or a very bright light bulb, 
bright enough to fully light up a room completely where the whole room is lit bright ?

please show me...

Just to let everyone know my Bucking Joule Thief results are getting better. I do not have any fancy drawing program so I will see if I can find someone who might be kind enough to make a drawing for me. However first tests are in:

1.05 Starting volts on battery A and 1.16 on battery B. I then added two pick up coils at 90 degrees to the JTs and 180 to each other. I used photoflash caps 120uf 300v caps and a 1n1004 blocking diode on each. starting voltage was empty.

I then ran the circuit and manually switched back and forth. After 1 hour the starting battery's where at 1.13 and 1.22 and the caps had collected 30 volts on 1 and 14 on the there other.

The are a few things to remember the switching is by hand at this point. You have to have blocking diodes on the JT battery when they are in what I call Receive mode.

This does seem to work and I did notice extra energy on the circuit. I think the back-emf is what is kicking the batters up on voltage. And I do believe that they would need to be ran for 30 to 50 cycles like this before they would hold that charge.

However they are charging and doing real work at the same time. Its a simple circuit that should be easy for anyone to replicate.

What do you guys / gals think?

In this test I have two wireless tower's.The first one is 16" away from the main coil and the second one is 29" away.
The first one has 40 led's on it and the second one has 20 led's.
First I have it running off the cell phone charger then I also show it running off a 6v sla battery.

Here is the video.

That is a pretty tall order for something powered by a used 1.5 battery.  However, with the lights I, and others have made and shown here, if you run several of them at once, depending on the size of the room, it gets to be pretty bright.  I can use rechargeable batteries and recharge them from the EER or one of my Bedini chargers for free so no cost there.

I had three of my lights running at the same time the other night and my room was pretty well lit.  Jeanna's light with the globe she fabricated does an excellent job and I would bet 2 or 3 of them would light a room nicely.

But, as of right now, I don't have any single lights powered by 1.5 volts that will do that, and I don't recall anyone else having one either, although, as usual, I could be wrong.
