Simple DC to AC inverter using step up mini-transformer

An interesting circuit using mini step up transformer, TIP41C NPN Transistor, and 240 Ohm resistor. The transformer consist of 2 Phase Primary and 1 Phase high voltage secondary - using the TIP41C as the switch to oscillate the AC signal to step up the voltage. In this video shows how it can step up 3.7 volt DC battery (18650) into 400++ volt AC to power up an LED bulb rate at 220 volt @ 3 watt.





This is very good circuit that can light up the bulb even at 0.8 volt (800 mili-volt) - can be useful for those who lives in remote area.
