In this Design Idea, we look at how electromechanical relays display hysteresis behavior that is surprisingly similar to the solid-state Schmitt trigger circuits, and how they can be used for many similar applications...

TinyCharger is an ATtiny25/45/85-based, single-cell Li-ion battery charger with selectable charging current limit (100 mA - 1000 mA) and an OLED display for monitoring...

Some years ago, back in 2005 to be specific, the project was a power supply for a low Earth orbiting satellite. Part of our digital circuitry involved some logic gating using Exclusive-OR...

As a youngster, I saw some really old radios; the kind that occupied highly-polished wooden cabinets the size of a refrigerator. When those old radios were made, permanent magnets were not all that powerful, and they were quite costly...

Diodes Incorporated introduces the PAM8907 piezoelectric sounder driver, for maximizing sound pressure level delivery from a ceramic/piezo sounder...

A universal problem in battery-operated devices is the threat of damage when an end user (never an engineer) inserts the battery backward. You can avoid damage by inserting a single diode or by using a diode-bridge configuration, but those fixes waste power and reduce the supply voltage...

It is not often you get to write a title like the one above. The main methods of generating electricity have been know for years, decades or even centuries...

Air pollution is the presence of excessive amount of unwanted & harmful solid and gases substances in the air. Cause and Effect of Air Pollution Recently, many cities in the world have encountered rapid urbanization...

This circuit increases the repeatability of noise test setups by providing reference points in the noise-vs.-frequency output generated by the network analyzer...

Contactless washbasin taps that can dispense water without the risk of communicating diseases can play an important role in the battle against the COVID-19 virus...
