In this Arduino project, I show you how to build a simple servo laser tower controlled from a smartphone app called Blynk.

We can use them to cut things, create laser light shows, and also as a rangefinder. [Ignas] wrote in to tell us about [Berryjam’s] AMAZING write-up on creating an Arduino based laser rangefinder.

If you’re interested in building your own laser sky effect generator, you’ll need a few key components: an Arduino Uno, a laser module, mirrors, motors to spin the mirrors, a photoresistor, an ...

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.

You'll need an Arduino, of course, and you'll also need a pair of laser pointers, a few servos and motors to make the lasers move as time passes, and of course, the IKEA BLANDA salad bowl ...
