220v to 12v without transformer
Hello friends, today in this video I have shown how to make a 220v to 12v converter circuit. Please note, this circuit is not isolated from mains so don’t touch any naked wire in this circuit when the circuit is plugged in.
If you want to increase the brightness of the led use 10W led and 2.2uf ceramic capacitor in place of 1uf. This capacitor must be rated 400v or above.
