Laser anti theft circuit (PCBWay.com)
This circuit is a simple laser anti theft alarm with SCR, laser, LDR and a few other components.
When the theft body cut the laser beam, the buzzer turns ON and latch (stay ON) until the Reset button pressed.
I designed the PCB in the shape of tiny house (my YouTube channel logo)
