The YouTube channel DIY Builder has published and created a DIY Arduino laser engraver which is powered by an Arduino Nano development board and is fitted with a 200-250mW 650nm Laser Module. Check ...

One of the great things about home automation is that it’s limitless. Whether you add more smart locks, toss some smart light bulbs into lamps, or add another smart thermostat to your home, it’s ...

TheMIDInator MIDI controller has been created by Switch & Lever using an Arduino Mega with its 54 digital IO and 16 analog pins to provide a wealth of inputs enabling data to pass onto a digital audio ...

In this fun project an ultrasonic distance sensor is used to detect a “target” (i.e., a person, a cat, a burglar, etc.). The Arduino illuminates (blasts) the target using an inexpensive laser diode ...

In this Arduino project, I show you how to build a simple servo laser tower controlled from a smartphone app called Blynk. This is ideal for making a toy for your cat or dog. #ArduinoProject #CatLaser ...

The creative adventures with ATtiny series microcontroller are awesome if you know how to play them. ATtinys — especially the ATtiny85s — are all around us, and by using one, we can shrink the size of ...

Researchers have developed a new way to control and manipulate optical signals by embedding a liquid crystal layer into waveguides created with direct laser writing. The new devices enable ...

Engineers create something out of nothing, and no where is this more apparent than in the creation of customized computer hardware. To make a simple MIDI controller, you need knowledge of firmware ...
