A big hello to all mankind! Visit my youtube channel to 
and find various interesting things on Electrical ~ Mechanical and Electronic ~ Technology...
 
Buying one helps my research tremendously,
 helping me get all the supplies I need for the future.
Super Efficient Joule Thief to steal all the last energy from AA battery 
"works from 0.6 volts to light up 10 leds / 10mm" and without any Toroid coil. 
 
In half operation it lasted illuminating about for (170) hours with those bad non-branded battery
 
A joule thief is a minimalist Armstrong self-oscillating voltage booster that is small, 
low-cost, and easy to build, typically used for driving light loads.
It can use nearly all of the energy in a single-cell electric battery, 
even far below the voltage where other circuits consider the battery fully discharged; 
hence the name, which suggests the notion that the circuit is
 stealing energy or "joules" from the source. 
The term is a pun on the expression "jewel thief": one who steals jewelry or gemstones.
 
 
Ηow to operate it
 
There is a "green" power potentiometer rotary switch. To operate the device and 
to increase the intensity of the Leds! 
 
Use all your old ΑΑ batteries to discharge them completely and 
you will have light in times of emergency...
NOTE
 
Maybe there are small differences in electronic components 
and materials (like bigger batteries etc) due to device enhancement for the buyer's benefit!
