This is a project I made in 2015 and now publishing. The core of the Project is a hardware made out of two CD drive stepper motors an mechanics, two L298 motor drivers and an arduino Mega. The one ...

What is a CNC Laser Plotter? CNC stands for computer numerical control. The Arduino CNC laser plotter moves its parts in accordance with the instructions it is provided in order to draw a desired ...

An impressive persistence of vision laser projector built using an Arduino and a hard drive case has been demonstrated by a DIY enthusiast. The device uses a circular array of rapidly spinning mirrors ...

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 ...

Once, long ago when magazines still existed, I bought a copy of Popular Mechanics. Inside was a guide on how to build a robotic lawnmower. Now this was back in the 1980s so it wasn’t a very complex ...

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 ...

There’s nothing fun about a Sisyphean task unless you’re watching one being carried out by someone or something else. In that case, it can be mesmerizing like this Arduino-driven kinetic sand table.

Abstract: This study presents the development of a LASER power controller using pulse-width modulation (PWM) technique for the 3-axis computer numerically-controlled (CNC) LASER Machine. This includes ...
