When we think of relays, we tend to think of those big mechanical things that make a satisfying ‘click’ when activated. As nice as they are for relay-based computers, there are times when you don’t ...

With a few mouse clicks you can easily purchase Solid State Relays (SSRs) online. Or you can make one at home with a handful of different electronic parts. The question is– should I buy it or make it ...

“You could’ve done that with a 555 timer.” But what if all you have on hand is an ESP8266? [TechColab] needed to control a solenoid valve with a short pulse via a solid-state relay (SSR) but found ...

Hybrid relays are changing the way we think about switching inside electronic circuits. By combining the fast response of solid-state components with the reliability of mechanical contacts, these ...

Electromechanical relays for testing products ranging from automotive engines to thermocouples are readily available, low-cost devices you can use to route signals originating from almost anywhere. It ...
