Since the laser diodes only put out one wavelength of light, the beam bends but does not split or diffuse.

The control system is build around the simple Arduino shield shown to the right, which uses simple 74 series logic to send TTL control signals to the laser diodes used in his rig.

Light fidelity (Li-Fi) is a widely adopted form of wireless communication that uses optical energy to verify device ...

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.

Called RLD90QZW8, “original technology allows Rohm to reduce the temperature dependence of the laser wavelength to just Δ11.6nm – 0.10nm/°C”, said the company. “This makes it possible to narrow the ...

The Arduino illuminates (blasts) the target using an inexpensive laser diode mounted on a servo motor. Interesting applications of applied math include computing distance based on sonic travel time, ...

Mr Beam is a laser engraver and cutting machine which is powered by the Arduino platform and is capable of cutting paper, foil, cardboard, foam rubber, foam board, felt, leather and even chocolate ...

The laser diode outputs can tolerate voltages up to 10 V to make it possible to use laser diodes with a high forward voltage. In addition, power control for the laser diodes is performed by ...

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 # ...
