[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 ...

Interesting article – I particularly like the chained SSR/Relay gambit, but as a side-issue it’s interesting to note that counterfeits are so prevalent that we now sort of design around them ...

He thought the best response was to devise a device that could read faint signals. The galvanometer, first invented in 1802, was a means of detecting electric current. It consisted of a needle ...

Galvanometer optical scanners also called Galvos or Galvo scanners are motorized mirror mounts and systems used for laser-beam steering or scanning applications. They are ideal for moving small laser ...

Thermal overload relays are protective devices. They are designed to cut power if the motor draws too much current for an extended period of time. To accomplish this, thermal overload relays contain a ...

THE electro-capillary machine of Lippmann and his capillary electrometer, besides the capillary electroscope of Werner Sieinens and the electro-chemical relay of Wheatstone are all illustrations ...

An attacker exploiting the security issue could relay NTLM authentication to Active Directory Certificate Services (ADCS) to obtain a user certificate for further domain authentication.

There’s no mistaking the 2015 Citroen Relay for anything else on the road – you can thank its huge chrome grille and bright, but optional, LED daytime running lights for that. You could also ...
