Joule Thief

@xee2

You got that right , but if you don't use a diode bridge and use them in a closed loop with anything you will kill efficiency buy sending voltage the wrong way, the toroid is like a bucket of water always full and the joule thief make a wave in it we need to only pickup what falls to the ground , syncronyzing the pulse will yield bigger waves more output, if we sent what falls to ground in in f**ks it up adding opposite waves.

But yes you will see some ac .But not everyone check ac and dc reading.

The double jt could most likely give us a lot more when tuning the pulses .

@all

I dont know but this thread is going too fast for me to follow.
I will do my best to read each post. There are 88 pages now, maybe when I come back there would be a 100.
Thank you all for sharing the information.

Happy new year!!

VERY NICE.

Thank you for being so clear.

I used my little torroid jt which has 10 bifilar winds and wound 40 times around that starting and stopping at approximately the same place using 30 gauge mag wire. (red mag wire from radio shack) The total length of this secondary was only 40 inches, so I  threaded a yarn needle (fat-big eye-not sharp) and sewed my way around.  HA!

Jim, you must be a weaver or a sailor to come up with the excellent suggestion to make a bobbin. very nice.

Anyway, I am only getting light from the secondary.

Did I miss something? do I need to just use  the secondary to get more than 1 light?

Is it that I am using the 1Kohm resistor?

HELP!

thank you,

So i assume the secondary (pickup and 3rd coil) , you can connect a led to it it will light, but preferable to use 4 diodes lets say 1n400x

Like on the picture , connect the secondary coil to the ac (little waves like in the bucket) side of it and the led to the dc (+ and -)side.

So we will be using rectified ac, which is now dc with a better wave configuration (Like the guy said in the 1st video) and hence, make use of all the available energy.  Excellent.  Thank you for the bridge rectifier drawing.  I was never clear where to tie into them, or where the output was.
