Help with Laser Alarm Circuit
A new user has recently discovered a Laser Alarm System and has decided to explore this project.
The Laser Alarm System is a security device that utilizes laser beams to detect unauthorized entry or movement within a designated area. The fundamental...
Scoobas Solution Sensing Tactic
This document serves multiple purposes, primarily to document the methods employed by a Scooba robot to detect: a) the presence of an acceptable cleaning solution being delivered to its pump, and b) the excess presence of used solution collected off...
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...
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, one utilizing the flash from a disposable pocket camera, and...
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...
Home-Built Nitrogen (N2) Laser
The nitrogen (N2) laser generates extremely short pulses of light (lasting a few nanoseconds) with a typical intensity of 100 kW in the near ultraviolet (UV) range of the electromagnetic spectrum, specifically at 337.1 nm. Despite its impressive capabilities, the...
NC visible laser modulation driver circuit
The laser tube drive circuit typically incorporates a photodiode that generates a laser beam proportional to the intensity (optical power) of the current. However, this type of photocell is generally slow and unable to track modulation effectively, particularly for peak...
Diode Sensor For Lasers
Laser-receiver circuits must bias their avalanche photodiodes (APD) to achieve optimal gain. Unfortunately, an APD's gain depends on the operating temperature. The circuit controls the operating voltage of an APD over a large temperature range to maintain the gain at...
