This is my Hand Crank Supercapacitor Joule Thief

New Prototype circuit.

It is a very high efficient JOULE THIEF based circuit. 
It has a Supercapacitor and it can light for over 30 minutes with only 35 seconds!
of hand charge to power the 10mm super bright Led.
The power consumption ranges from 0.003mA to 0.025mA & the voltage from 0.25mV to 2.7volt.
It is adjustable in brightness via a potentiometer to meet your personal needs.
 
 
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" potentiometer is to increase the intensity of the Led! 
and the blue crank is to turn and charge the super capacitor.
 
 
 
NOTE
 
Maybe there are small differences in electronic components 
and materials (like bigger batteries etc) due to device enhancement for the buyer's benefit!
