A laser projector creates a light show that seems to be coming from dozens of laser beams. It only needs a single laser beam to create the effect because the beam is diffracted as it emerges from the ...

This is to ensure the projector is not randomly turned on or off when the Arduino is reset. You must toggle the amplifier's state to turn the projector on or off after Arduino reset/startup. The green ...

An impressive persistence of vision laser projector built using an Arduino and a hard drive case has been demonstrated by a DIY enthusiast. The device uses a circular array of rapidly spinning mirrors ...

The only required electronics are a small projector and a single photodiode. ... This is a very simple hack: an Arduino sits inside a 3D-printed case that holds a big, red button.

I have a shinp DMX 50mW projector that uses a Nuvoton 40 pin IC to take DMX in, a microphone input for ‘beat detection’, drives 2 stepper motors, and controls the laser via ttl driver board input.

Ben Purdy apparently kept his imagination nimble and, with the help of a projector, a piezo element and an Arduino (of course), turned a plain ol' box into a real life Minecraft block.
