[Peter] is calling this a “long lines relay” after old AT&T microwave technology, but it is essentially two Heltec modules set up to operate as Meshtastic nodes, where one can operate as a ...

Before today, we probably would have said that scratch-built relay computers were the sole domain of only the most wizardly of graybeards. But this impressive build sent in by [Will Dana] shows ...

Relay sockets accept electromechanical switches in which the variation of current in one electric circuit controls the flow of electricity in another circuit. Relay sockets are made of metal or ...

Advances are being made by the Science & Technical Research Laboratories on broadcast-wave relay technology with a view toward constructing a relay station broadcast-wave network at a low cost.

STRL developed this camera and has continued to enhance it. In this issue, a millimeter-wave mobile camera system for sports relay broadcasts by using the example of a golf program will be described.

The primary objective to the trader, and the aim of this dedicated page, is to identify the presence of the most destructive and thereby profitable wave formations, be they a third wave or a C wave.

Like gasoline-only generators, dual-fuel models convert fuel into electricity, but since they run on either gas or propane, they are more versatile. Dual-fuel generators vary in quality ...

A CPU chip that contains two distinct processing units that work in parallel. IBM introduced dual core Power 4 CPUs in 2000, followed by Sun and HP in 2004 and x86-based Pentiums in 2005.

Wave washers, also referred to as wave springs, are wavy metal washers designed to provide a compensating spring force or absorb shock when under load. Many design variations have evolved to best ...

A sound wave is a vibration that travels through a solid, liquid or gas such as the air or water. A loud sound has a large amplitude, a high pitched sound has a high frequency. Musicians and ...

In November of 2020, a freak wave came out of the blue, lifting a lonesome buoy off the coast of British Columbia 17.6 meters ...
