A diode allows current to travel in only one direction. With that in mind, [Alex] built a mechanical diode that will only allow gear rotation in one direction to be transmitted through the system.

The history of the diode is a fun one as it’s rife with accidental discoveries, sometimes having to wait decades for a use for what was found. Two examples of that are our first two topics ...

The PCI clamp diode limitsthe voltage to a level that doesn’t harmthe input, and the resistance value limitsthe current to a safe level that doesn’tharm the PCI clamp diode. This approachworks well in ...

A diode is a device that allows electric current to flow in only one direction, from its anode towards its cathode but not the other way around. There is plenty of online material explaining diode ...

Recently, ‘Liquid crystal display (LCD) vs. organic light-emitting diode (OLED) display: who wins?’ has become a topic of heated debate. In this review, we perform a systematic and comparative ...

The four-layer diode was the key to William Shockley's plan to revolutionize AT&T's phone system. It was a great device in theory, but not in practice -- at least not at the time when Shockley ...

Examining the superconducting diode effect Date: October 2, 2023 Source: ARC Centre of Excellence in Future Low-Energy Electronics Technologies Summary: Scientists have reviewed the ...

Claimed to be the first-ever “magnetic field diode”, a device in which one wire coil can transfer its magnetic field to a second coil, but not the other way around has been created by Jordi Prat-Camps ...

It might better be described as a ‘nearly ideal diode controller’ as it draws some current from the output circuit when no input is connected – 147μA if a 12V battery is connected to the output in the ...
