Recently, [Manuel] did a post on making logic gates out of anything. He mentioned a site about relay logic. While it is true that you can build logic gates using switch logic (that is, two switches in ...

The project is designed to provide low voltage start to induction motors. This is achieved by using star to delta conversion. Star/Delta starters are probably the most common reduced voltage starters ...

If you work on cars you’ve probably heard of relays; in fact, we often cover using relays in our tech articles. Following detailed instructions to wire one can work, but understanding what makes them ...

A relay module is an electrical component. Various industries use this circuit board that houses one or more electric switches or relays in different circuits and electrical projects. Relay boards are ...

Most test setups need only positive voltages to power the device under test (DUT). Some devices require negative voltages as well. Test voltages aren’t always fixed, though. Their value and/or ...

The 1-Wire Net, or MicroLAN (by Maxim-Dallas), is a simple way to connect slow devices (such as sensors, relay drivers, switches, and so on) using simple components. These components contain the ...
