Joule Thief. Amazing Hand Heat Energy. 0,1 volt part 3
A Peltier element delivers a small voltage up to 2 volts, when it is cooled on one side and heated on the other. Heat from my hand gives only 0.1 to 0.2 volts.
I have to start the Joule thief with my soldering iron, so it goes into oscillation.
Note that the red led are connected between Collektor and Basic. It gives much more light in the LED
Normally leds are connected between Collektor and Emiter, it is bad.
Input 0,1 volt, output 1,8 volt
