Its my first post , today i am posting about " how can you make your own Laser Security System", its very easy and cheap, you could find many of the components at your home , the mechanism is very simple, a laser beam guards your stuff , if some one tries to touch your stuff the beam is broken and the buzzer beeps you could even connect a camera on the place a buzzer so that a picture is also clicked, you just have to solder the switch to the place where the buzzer is jointed, and its made.
