AC light flashing power lamp using SCR

This circuit uses a half cycle of AC power Voltage , for feed give with AC Lamp. The part again a half cycle that go to give with capacitor C1. For build voltage to feed reach a pin G of SCR. When arrive at the dot at firing angle SCR will lead the electric current and let Current at still remain again a half cycle. This change reach at AC lamp make lamp stick can wink. By capacitor appraise 100uF 50V, R1 equal to 2.7K , R2 = 22K , R3 = 3.3K , VR4 = 100K use for fine the speed in winking of Lamp. D1-D2 number HEP R0053 ,SCR number GEC106B1 , which set up on let off the heat with.
