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.

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

2 * Arduino Uno or similar. (anything with an analogue read pin will probably work) LDR (light dependent resistor) 10k ohm resistor a laser diode Using the wiring diagram, assemble the circuits for ...

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, ...

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 Arduino Uno Laser Diode Module emits a focused beam of laser light. It typically includes a laser diode and a driver circuit, allowing precise control of the laser output. Used in applications ...

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 ...

This paper adopts Arduino DUE and Raspberry Pi for organic light emitting diode (OLED) lifetime measurement. Using digital-analog converter (DAC) port of Arduino DUE output voltage to control the ...

A German project has revealed 400W infra-red laser diode bars for welding metals. “About 10 years ago, the best laser bars achieved a power of 200W with an efficiency of about 63%,” according to Osram ...
