today in this video i have shown how to make a 220v to 3.7 v Transformerless Battery Charging Circuit. Please note the circuit is not isolated from maims so don't touch any naked wire in this circuit when the circuit is plugged in.
Parts list:-
105j / 450v pf capacitor
1M resistor
1N 4007 diode
470uf / (16-25v) capacitor
5mm green LED
330Ohm resistor
This video is educational purpose only.High voltage can damage your life. Some works can be dangerous. and for that, you don't risk and damage your self. I am professional in my work. So without knowledge don't try this.
