We need safety and security for our valuable things, to protect our property simple and robust security alarm circuit designed by using commonly available components. We know the LASER (Light Amplification by Stimulated Emission of Radiation) light has high strength-focused light rays, in this project we have used that laser ligh...

Laser Alarm System Trigger V2
By: Tyler Le
This is the second model of the receiving end of a DIY laser-based alarm system. The first one will not be published. Also, this circuit has been tested on a simulator [http://www.falstad.com/circuit/] and it seems to work great.
This alarm will normally have a laser shinin...
This is a device that cuts anything that breaks the laser line. Once the photo resistor (PRA, PRB) detects no laser (LD+, LD-) , the motors (M1A, M1B, M2A, M2B) will start to spin. The motor shafts are connected to sharp blades that cuts. C2 is normally charged, when the device is triggered, C2 will discharge through the electromagnet 1 (EM1A, EM1B). The electromagnet 1 will release a sharp metal...
