Menci alarm produced schematic circuit diagram
The alarm circuit operates as follows: When the power switch SW1 is turned on, the alarm system becomes active. If a magnet is brought close to the spring, the magnetic field attracts the spring, causing the dynamic and static switch...
laser trip wire circuit
A replication of the Afrotechmods laser tripwire circuit utilizing a simple laser pointer, an IRF244 MOSFET (most NPN transistors would also suffice), a few resistors, and one light-dependent resistor (LDR).
The Afrotechmods laser tripwire circuit is an innovative application of basic...
Laser Power Supplies
Construct universal power supplies, including low-voltage power supplies for operating electronic equipment. The designs include single- and dual-voltage regulated supplies, an all-purpose adjustable version, and battery pack regulators. A helium-neon laser tube requires a high-voltage power supply for operation.
There...
Laser beam Sensor
a more complex detector circuit which turns the relay on for an adjustable period of time. When the beam is broken, the LED goes on, your effect is powered, and capacitor C1 begins charging. As C1 is charging, the transistor...
Stabilizing a laser discharge current
The circuit employs a free-running push-pull DC to DC high voltage converter to generate the required voltage for the laser plasma tube supply. The supply voltage (Vc) of this converter is regulated by a switch-mode power supply to maintain a...
Automatic Room light Control With Bi Directional Visitor Counter
The objective of this project is to create a controller-based model that counts the number of individuals entering a specific room and activates the lighting accordingly. This is achieved through the use of sensors that detect the current number of...
Field disturbance sensor-alarm
The change in ambient light triggers the alarm by changing the resistance of LDR1 and LDR2.
The circuit utilizes two light-dependent resistors (LDR1 and LDR2) to detect variations in ambient light levels. LDRs are passive components that exhibit a change in...
Security-door-ajar-alarm
The TL3019 device activates, or goes low, when a south pole of a magnet approaches the chip face. In this example, there are five doors, each equipped with a magnet embedded in its edge, with the south pole facing outward....
Complete SS Laser Power Supply Schematics
This chapter contains circuit diagrams for several power supplies designed for pulsed solid-state lasers. These include units suitable for driving the widely used Hughes ruby and YAG rangefinder laser assemblies, one utilizing the flash from a disposable pocket camera, and...
