Joule Thief

[slayer007]

This is a basic joule theif circuit done with a big coil.
The coil I used is a trifilar coil.
It has a 23ga. bifilar winding 750 turns.
Then a 21ga. 450 turns wound on the out side of the two 23ga. windings.
With an iron core.
The + is the start of the coil and the - is the coil ending.

The interesting thing is when its running to place a magnet on the front of the coil.
Then it really takes off and you can hear the coil screeching.

@All

3 days away is to long to much reading to do.

Welcome to every new posters , those of the energetic forum people sharing there forces , that's the way i like it! Some of you have posted real important things in the early pages , but the nature of the forum you need to repeat  really feel free to , the learning curve for some is steeper then others , all your experiments are important , even if it takes a month before get the significance of it.

Really there are now so many people thank without missing anyone , you are all needed never forget that!

@all

I have made a 3 core jt it works but out from core one is regular second one it starts dropping a and the last core has about 2/3 of the first core output ,on this first try i only connected each side of the cores in series, this was only to see results and it is not the optimal way to do it but it works.I got decent voltage from all 6 pickup coils 20 volts and up.

@Slayer007

It works with only one magnet ?A second in reverse polarity at the other end of the core doesn't work?
