Lasers are some of the coolest devices around. 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 ...

Instructables user [PenfoldPlant] is a big fan of indoor rock climbing, and while watching others make difficult climbs, he has often wondered if he could follow the same route up the wall.

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 laser pointer. The following is excerpted from the ...

A smart laser tripwire system built with Arduino that detects motion or interruption of a laser beam and triggers visual and audio alarms. Includes IR remote override control and an LCD screen for ...

Jon Bumstead has created an awesome Arduino powered 13 note midi harp after receiving funding from the optics group Spectra at Washington University in Saint Louis. Watch the video below to learn more ...

Abstract: A novel feedback system has been developed in order to mechanize laser ablation processes such as laser cleaning. This is aimed at improving the safety and productivity (cleaned area/time) ...

Two LDRs are placed such that they sense light from different directions. The difference in light intensity from the two LDRs is measured. Depending on which side is brighter, the servo motor rotates ...

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 and ...

Laser cutters are great DIY tools, but they're pretty expensive. If you'd prefer to build your own, Instructables user SilverJimny shows you how using an Arduino. The build here uses an Arduino along ...
