POSITAL’s high-performance IXARC optical rotary encoders are now available with EtherCAT communications interfaces. EtherCAT (Ethernet for Control Automation Technology) is a special form of ...

Here’s a fun build from [RootSaid] that is suitable for people just getting started with microcontrollers and robotics — an Arduino-controlled two-wheeled robot. The video assumes you already have one ...

You know how you can feel when someone is looking at you? Thanks to a person detector, [Michael Rigsby’s] little robotic light switch also knows when you are looking at it. As you can see in the video ...

A transistor that operates with photons rather than electrons is often heralded as the next step in information processing, but optical technology must first prove itself to be a viable solution in ...

Optical physics is the study of the fundamental properties of light and its interaction with matter. This includes classical optical phenomena such as reflection, refraction, diffraction and ...

Researchers at the ArQuS Laboratory of the University of Trieste (Italy) and the National Institute of Optics of the Italian National Research Council (CNR-INO) have achieved the first imaging of ...
