Arduino test code is run to see if the sensors are working properly, with built-in LED flashing when the sensor is triggered, ...

Fidget toys are everywhere these days. A particularly popular type simply puts some keyboard switches on a plate to provide a certain type of clicky satisfaction. [wjddnjsdnd] took that concept a ...

Abstract: Compact homodyne laser diode interferometers (HLDIs) can not only be applied as an instrument for off-machine measurement, but also be integrated into an equipment as a sensor for on-machine ...

Abstract: High precision time-of-flight based light detection and ranging (LiDAR) system needs compact ultrafast pulsed lasers, such as gain-switched semiconductor laser diodes, which have the ...

A cartridge-based console project that blends Arduino fundamentals, retro gaming nostalgia, and modern maker tools.

Laser wire scanners have been used for ion beam profile and emittance measurements at the Spallation Neutron Source linear accelerator. Due to propagation distances exceeding 100 m, reliable ...

Ultraviolet-B (UV-B) semiconductor lasers are highly sought for medical, biotechnology, and precision manufacturing applications; however, previous UV-B laser diodes were limited to pulsed operation ...
