Joule Thief

[gadgetmall]

@pirate . thanks i read it and i posted during before you posted i got a warning on my post before i posted ..SHEEEEESH .. yea im going to use anything i build . they will have to fight me for it !i want what you want . to use and share what me make .
@Jim
   Had the same problem . I got me one of those Live Traps .Macdonald's and other restaurants use them  you wind it up ,put some peanutbutter in the hole and the next morning you got a hotel full of Mice . It will catch up to 25 per wind . If you ask me what i do with them all i can say is i have a friend that dont have to but snake food anymore   

As far as the WOLF RATS  are concerned the cat is scared of them as they are as big as her .. 22 takes care of them ..they don't come round no more ..

Looks Nice ITS

You should be able to use just one of the coils as the joule thief.
Then use the others coils as slaves off the transistor of the JT.

When I tried it with mine it didn't seem to draw much more power.
And the other coils still put out a Lot of power.

@jeanna

Is it this what you meant with your explanation?
Feel free to do any changes to the graphic.

@jesus,
My graphics software is still gone, so I will leave it to you to mod your pic, if I may.

BTW thanks for posting the evilmadscientist pictures of making a joule thief little toroid style. It helps, I am sure.

!- the rectifier diode is only used to measure the rectified voltage coming off the single turn. It may be what you mean, but I want to be clear that the voltage going into the array of lights is NOT rectified.

1a- so, the drawing of the single wind around the hand wound toroid should perhaps show that without the diode bridge, the secondary feeds to the array of lights.

     Does that make sense?

2- The led you call blue or white is the one I removed after I was sure the circuit was working.

Thanks for making this drawing.

(I have even lost the original of that which I posted in december.)

@ all

The reason i posted the earth battery is  it is a jt.Yes many worked on Stubbulfield but none got it to a useful voltage,There is magnetic factor to raise the voltage , most a have seen are jokes sorry! But we can do better now.

It takes the galvanic voltage and pulse the magnetic core with a pickup coil on it for output.The jt to transistor are needed because earth gives us some nice ac .
