LASER LINK COMMUNICATOR
As before, there are two sections: the transmitter board and the receiver board, both powered by a separate 9V battery or a fixed voltage power supply, depending on your needs. The transmitter board has an electret microphone module at one...
toy laser gun
A broken RC car remote shaped like a pistol was discovered in a toy box, leading to the idea of modifying it into a toy laser gun. A cheap laser pointer was also available for the project. Unfortunately, pictures of...
A simple TTL modulated diode laser
The circuit measures distances using a modulated laser. It features a fixed voltage regulator (7805) that provides a stable +5 V source, followed by an LM317 adjustable voltage regulator to supply exactly 3 V to the diode laser module, as...
automatic laser poweroff circuit
Here is the automatic laser power-off circuit schematic. This circuit features a visible power indication. In this case, the ground is connected on one side.
The automatic laser power-off circuit is designed to enhance safety and efficiency in laser applications by...
LASER Transmitter/Receiver
In the transmitter schematic, a ballast resistor is not depicted because most small laser power supplies are typically equipped with an integrated ballast resistor. However, variations in power supply designs may require the addition of an external resistor.
In laser applications,...
disassembled key chain laser
A new user expresses interest in lasers and has purchased an inexpensive red laser pointer and LED light combination keychain.
The red laser pointer and LED light combination keychain is a compact and versatile device that serves multiple functions. The red...
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...
Laser Beams and 555
A laser trip wire that activates a camera. An ambient light sensor from Vishay, the TEMT6000, operates as an NPN transistor connected to a 555 timer in bistable mode. The output is directed to a logic inverter for quick visual...
Complete SS Laser Power Supply Schematics
This chapter contains circuit diagrams for various power supplies designed for pulsed solid-state lasers. These include units suitable for driving the widely used Hughes ruby and YAG rangefinder laser assemblies, as well as one utilizing the flash from a disposable...
