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.

The sensor uses a laser diode and a photodiode to detect and count particles, while a fan moves air through the system.

A new Arduino project has been posted to the awesome Instructables website this week providing details on how you can create your very own Arduino laser pinball machine.

Teledyne e2v has announced a family of CMOS image sensors for 3D laser triangulation – for use in applications such as distance measurement, profile measurement and high resolution physical inspection ...

Laser Blaster Last Updated: 7/27/18 Teaching Standard: 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 ...

In a chamber of dense, artificially created fog, the system was able to discern objects sitting beyond the limit of human visibility.

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 ...
