The control system is build around the simple Arduino shield shown to the right, which uses simple 74 series logic to send TTL control signals to the laser diodes used in his rig.

Some people have all the luck. [MakerMan] writes in to gloat tell us about a recent trip to the junkyard where he scored a rather serious looking laser cutter. This is no desktop-sized K40 we&#8217… ...

Thorin Klosowski 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 Arduino laser microscope is capable of providing 1300x magnification and attaining a resolution of 65,536 pixels (256 x 256) in an area of .05 x .05mm.

That’s when I saw several instructables (Laser Tripwire Alarm, Arduino – Laser Tripwire Alarm System, and Super Easy Laser Tripwire, among others) using a laser tripwire.

If you're looking for clever ways to repurpose any of the old CD or DVD players that might be scattered around your house, we ...

There are approximately a zillion DIY laser engraver tutorials on the Web, but of all the homemade builds we've come across, this one from Instructables user MichielD99 is definitely one of the best.

In this video, we take you on a fascinating journey into the world of robotics with the "Create Your Own Robot Spider" guide, ...

The purpose of this module is to create a cat toy that moves a laser with random motion. We will then use a potentiometer to control the speed of the laser. It ultimately provides a good introduction ...

Arduino has found its way into yet another musical device. I came across the 'UFO' while in Berlin. It's a MIDI controller that lets you compose music or control synthesizers by waving your hands ...
