POIT:

Nice job on the mA's.  That is decent.

thanks

An issue with it is that the salt in the water settles at the bottom of the glass after a while, and when this happens the voltage drops off and the mA drops down significantly, the water becomes less conductive and thus the chemical reaction between the copper and galvanised screws become less.... is there any ways I can fix this? make the water and salt stay mixed.. Sea water might be a solution?

Boil the salt water solution and use it when cold.

You could possibly use some type of cloth like cotton and wrap it. A few copper pieces could also be flattened with cloth in between,and then wrap cloth around that. This should hold the salt in better.
Dont know if this would work. Wrap cloth around the copper,then a layer of aluminum foil,then another layer of cloth. Dont know how long the foil would last or even if it would boost power.

Robbie (Kooler) !

It would be very helpful for newcomers (and also for people like me who try to advance their knowledge about the Joule Thief circuit and its derivatives)  if you could post your best JT-circuits here again .

You probably did show everything in this thread (or elsewhere) before, but it is so hard to find in the very many posts.

I also would like to ask other people (who are still around) to post their best circuit. There must be some five to ten good circuits around (hidden somewhere in this enormous heap of messages). Asking people to read through the thread from the beginning is kind of rude, because 90% of the posts are rather social and Freudian instead of technical.

Conrad,
I missed Kooler's more perfected circuit too.
I found it on his yt video and snapped a screen shot.
Here it is but without the very intriguing inductors he just mentioned.
