The Hartley oscillator is basically a frequency generator circuit where the oscillation frequency kind of hangs on what’s happening in a tuned circuit. That circuit involves capacitors and inductors, so […]

This circuit is essentially a straightforward heater or light dimmer controller and it comes packed with components that help suppress radio frequency interference (RFI) and includes a snubber network. Let […]

Almost every light dimmer available at typical electrical supply stores can only handle a limited amount of electricity. The power handling capacity is typically a few hundred watts. A power […]

Commonly dry run circuits mostly rely on water detection, which renders the designs quite antiquated and laborious. In contrast to these concept, the subsequent one relies on either load or current sensing […]

When there exists no water in the tank and zero water is flowing out of the pipe plug, the pump motor could be equipped with an efficient dry run protection […]

Six NOT gates from the IC 4049 may also be used to create a completely automatic version of a motor dry run protection circuit as seen below. This setup should operate […]
