Mini back-EMF system with coil oscillation circuit even can reach over 20V from 1.5V battery. But still no amperage…
Mini back-EMF system on the base of the joule thief with a transistor as a switch. Diode and capacitor added to schematic. 1.5V battery has 1.26V before connection (LED does not lights) and 0.92V during connection (LED lights with 3.04V). No OU though.
Because of enormous production of heat in previous setup (breaking contacts simple can’t withstand it) scaled down schematic to 6V battery, made mechanical switch running independently from 1.5V battery (on this scale it’s easy to adjust and maintain),…
Another setup for Back EMF system, now with 12V battery, one flatbar coil on transformer core, independent breaker system and 120V household bulb.
Back EMF circuit (on the basis of single transformer coil) but applied to 6V battery can light 12V bulb or develop up to 70V capacitor charge and retain the same battery charged. Instead of relay I’m using 12V solenoid coil breaking the circuit (in a w…
