The laser hits the light sensor, which registers a certain value. When something interrupts the laser, the value drops and the buzzer starts producing sounds. If key 1 is pressed three times on the ...

Sometimes security doesn’t need to be overly complex to be effective. Instructables user [1234itouch] recently built a simple laser tripwire alarm that can be mounted virtually anywhere, complete with ...

Abstract: Aiming at the disadvantage of current anti-theft alarm technology for substation perimeter security, a novel laser alarm system based on ZigBee is proposed in this paper. The alarm system ...

The Gun Operated Alarm Clock was a good conceptual design, but the Laser Target Alarm Clock has two things that its predecessor lacks. First off, it is vastly more challenging (and therefore annoying) ...
