Joule Thief

@ dog812

Wire diameter is not critical. Basic secondary circuit is as follows.

In this case the 27 turn coil would be used for the secondary. See jeanna posts for more info.

@renseak,
This is interesting that you can do this.
Please tell us the amps draw from that array.

Also, is there anything else that is different from the regular jt circuit in that? If so please supply the information.

@xee2,
I approve of your suggestions for the terminology and thank you for making it so clear. Now, if you go back (sorry) and add the joule thief light in its standard position between C and E and name it so, this will be perfect. Do you agree?

Also thanks for such a good drawing of the split jt wires.

@all,
Isn't it a worthy idea to always include the components (including number of lights and their arrangement) and amp draw/volts produced if known on anything you are posting as result?  This is such a long thread with so many contributors, it really helps me to have this information all together in one post.
