The control circuit in Figure 1a allows you to manually adjust the power delivered to a load. By changing the setting of potentiometer R 3, you change the phase angle at which the thyristor (Q 3) ...

The circuit was designed to produce a timing scheme that will provide a longer span of time to become activated. LM555 – a highly stable device for generating accurate oscillation or time delays with ...

Measuring extremely high dc voltages of 10 kV or more usually requires a suitably equipped high-voltage ohmmeter or a digital multimeter and high-voltage divider, along with the proper safety ...

The product marketing teams over at APC by Schneider Electric were kind enough to point out to me yesterday that THEY, too, have introduced surge protector this year that is endowed with power-saving ...

You have a timer and clock in just about every single device out there these days, but if you want to build you own, Instructables user GeraldF6 shows you how to do so with a Arduino. The project here ...
