Makers looking for a desktop laser cutter and engraving machine, might be interested in a new project which has launched over on the Kickstarter crowd funding website this week to create, Mr Beam. Mr ...

A laser projector creates a light show that seems to be coming from dozens of laser beams. It only needs a single laser beam to create the effect because the beam is diffracted as it emerges from the ...

A lot of the DIY laser engravers and cutters we cover here on Hackaday are made with laser diodes salvaged from Blu-ray drives and projectors, which are visible lasers in the 400 – 450nm range ...

Every laser cutter enthusiast eventually pops the question: how on earth do I align an invisible beam that’s more-than-happy to zap my eyeballs, not to mention torch everything else in its path? We ...

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 ...

A fiber-coupled module featuring a working operational beam and optical red aiming beam. Well-suited for many medical applications as well as range-finding, illumination systems, and industrial ...

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 ...

Self-balancing propeller beam using Arduino, MPU6050, and PID control. This project is a self-balancing beam system controlled by Arduino using a PID algorithm and an MPU6050 IMU sensor. It maintains ...

The PMH laser-diode module is specifically designed to address the need for high-speed beam modulation up to 100 MHz. The device is capable of 2-ns rise and fall times and exhibits a propagation delay ...
