In this project, we create a joystick-controlled laser by connecting two servos to a joystick and using this setup as a pan-and-tilt controller for a ...

In this fun project an ultrasonic distance sensor is used to detect a “target” (i.e., a person, a cat, a burglar, etc.). The Arduino illuminates (blasts) the target using an inexpensive laser diode ...

Instructables member Patrick Panikulam has created a versatile wireless Arduino pen plotter and laser engraver, powered by an Arduino UNO microcontroller and offering a work area of 200 x 162 mm ...

A multi-institutional team of physicists and engineers has developed a laser-based radiation detection system that operates from as far away as 10 meters and perhaps farther. Their research is ...

Escort's newest radar and laser detector takes a page from the Valentine One book, with arrows to tell you where the threat is coming from. Read more at Car and Driver.

One of the essential parts of any home security system is a door detector that lets you know when a door opens. Over on Adafruit, they show you how t ...

And into the arms race between ever-more-sophisticated radar technologies and the devices designed to detect them enters Escort’s new Max 360 radar and laser detector, which the Ohio-based ...
