Peter MiĊĦenko mail
What is it used for? It is used to suck all the remaining energy from a not completely dead battery to illuminate the LED. Or just as simple LED driver to powering a white LED from a low voltage source. AA battery Why did you make it? This is unique device with an on board coil. I wanted a true, original joule thief but without winding toroid transformer What are some special features? I replaced toroid transformer with PCB etched dual coil
