If your Blu-ray player has gone from being the centerpiece of your home theater to a dust-collecting ornament, here’s a project for you. Doctor Volt recently published a post explaining how to transform a Samsung BD-J5900 Blu-ray player into a laser scanning microscope. One of the main advantages of a laser scanning microscope over optical…
In this project we will see a table football that detects the goals from both doors and displays the result on an android tablet. The circuit is very simple: an Arduino Mega detects goals through two photoresistors and two laser diodes. Arduino sends the necessary data to the Android tablet via the USB connection. More…
This instructable explains how to make an anemometer from an Arduino Uno R3, two VL6180X laser distance modules, and a section of plastic drain pipe or similar. Processing3 is used to display the wind speed and wind direction. The wind direction is independent of the pipe dimensions. The sensitivity to wind speed depends on the…
Lasers have always intrigued me. I have two Helium-Neon Lasers (gas discharge, not solid state), one red the other green. I also have several laser pointers. I like lasers. Several years ago I came across an instructable that showed that you could take the narrow beam of a laser and spread it out into…
In this project we will see how to make an anemometer (instrument for measuring wind speed and direction) using an Arduino Uno R3, two VL6180X laser distance modules and a section of tube made of plastic or similar materials. We will also use Processing3 to display wind speed and direction, the latter being independent of…
Lasers are awesome. Glow-in-the-dark surfaces are, too. As seen here, Justin and Brett were able to combine the two into an excellent drawing machine made from scrap materials and discarded wood. Their device uses a pair of gearmotors under Arduino control to actuate a rack-and-pinion gantry system over a canvas painted with phosphorescent powder. A…

MotionPro 6600 is a new motion controller development board for any electronic project with moving parts such as milling machines, robots, mechanical arms, sliders or moving part machines. Designed for any application or project that uses stepper motors for fine motion control, the motionPro 6600 has been created for makers, developers and enthusiasts building : –…
It allows us to detect the presence and passage of an object thanks to the combination of a laser diode which emits a light ray and a phototransistor which detects reflected light. Robotics applications and industrial control systems normally make use of optical systems in order to detect proximity and passing of objects,…
By making use Raspberry Pi, we created an easy to build 3D scanner to be used for the acquisition of three-dimensional models via a video camera and a laser 3D printing keeps on establishing itself, mostly thanks to the availability of more user-friendly 3D printers and price drops. Those who use a 3D…
MichielD99 is a 16 year old Belgian teenage maker. It is amazing that, with the tools and materials available today, a young person, really any person, can create something as sophisticated and professional-looking as this laser engraver. To drive the machine, he used an Arduino UNO with two NEMA-17 stepper motors and stepper motor drivers…
May the Force be with you! Great project dedicated to all of us born in the “Star Wars saga” years. If you dreamed to be a Jedi or a Sith, now you can purchase on Kickstarter the spare parts to build your own laser-sabre and all the accessories to be a perfect cosplayer! Still 10…
