We can use them to cut things, create laser light shows, and also as a rangefinder.[Ignas] wrote in to tell us about [Berryjam’s] AMAZING write-up on creating an Arduino based laser rangefinder.

We've developed numerous Arduino modules for various fields of teaching. Each section is divided into kindergarten through 6th grade and 6th grade through 12th grade. While some of these modules can ...

Powered by an Arduino Uno, this laser tripwire alarm project works much like those in movies. There's a tripwire — made up of a laser directed at a light sensor — that's placed ... a Bluetooth module ...

This high-precision module for air monitoring, developed by Renesas, includes seven sensors, an airflow fan, algorithms, and ...

The main parts are an Arduino Pro Mini clone, a BMP180 sensor and a Nokia 5110 LCD module. A standard 9V ... by enclosing the hardware in a custom laser cut acrylic box. The result is bigger ...

Laser scanning technology for building security applications utilises the time-of-flight method, in which a sensor emits a pulse that is then reflected by a target, if present. The time required for ...

The SHSLab is a powerful and comprehensive wavefront measurement solution from Micro-Epsilon. Developed by Optocraft GmbH, a ...

Pixel Voltaic, a spinoff of University of Porto, has launched a laser system to hermetically seal glass-glass and glass-steel perovskite PV modules up to 30 cm x 30 cm. The company’s technology ...

The best laser printers on the market are the ones that consistently deliver pages of high quality at lower printing costs than the competition, without causing you headaches. I know because my ...

microstructures based on laser speckle grayscale lithography. The RCA microstructures were used for fabricating highly sensitivity flexible capacitive pressure sensors. These sensors proved to be ...

When the first laser and inkjet printers for PCs arrived—in the mid-1980s—each could print only in monochrome, and their respective advantages were obvious. The differences are more nuanced ...

Both sensors measure rate of change; they just measure the rate of change for different things. In practice, that means that an accelerometer will measure the directional movement of a device but ...
