Using varistor instead of pot. to autom. adjust res. in joule-thief for bat.life

Sorry, I missed everything here I guess...

I'll take a closer look tomorrow, but that schematic is asking for a redrawn, badly drawn schematics brings a lot of confusion and just redrawing them makes things much more clear!

Distelzombie:
Well. Not much to change there. I don't know why you think it is badly drawn.  ???

I just removed the unnecessary switch that was there for testing purposes. If you have a simulation program I also uploaded the LTspice file, including the transformer I made for it.
Distelzombie:
Sry. I realized I had too many custom parts. I changed the SPICE file to work in stock LTspice. Schematic is still the same.
JS:
I will check it later, my LTS is a bit rusty as I usually use other tools, I'll see what I can do.

The placement of the parts inbschematics is quite a big deal, at the univ just by redrawing simple circuits as teachers gave them to us I got my bodys to understand it quite better, even if I got it as it was drawn. I haven't put much attention to yours yet, just a quick look to understand what's going on but not enoght to modify it to what you want.

Possibly I was unclear, the datasheet circuit replaces the whole joule thief circuit.  I believe the implication is that the average led current is roughly constant and the frequency fast enough to not be flickery.
