Although it dates back to the early days of the Marconi Company in the 1920s, the Franklin oscillator has remained a ...

In this video I’m showing how I’ve built a very simple battery backup circuit for my home alarm system. The circuit charges a 12v lead acid battery and in an event of a power loss, it transfers the ...

Although it dates back to the early days of the Marconi Company in the 1920s, the Franklin oscillator has remained a relatively obscure circuit, its memory mostly kept alive by ham radio operators who ...

An LM555 timer paired with an NTC thermistor makes a simple, configurable ON/OFF thermostat for heating or cooling.

We concluded part 2 of this series by starting to write node and loop equations for a five-resistor Wheatstone bridge circuit ...

Abstract: This study proposes a low-cost passive LC circuit-based temperature-measuring sensor network. The network allows for locating a position where an overheating event is occurring. The network ...

Abstract: In conventional WPT systems, soft switching is achieved by utilizing the reactive current generated by the resonant network. However, this reactive current circulates throughout the entire ...

This paper presents a novel design of an X-band (812 GHz) 4-bit monolithic microwave integrated circuit (MMIC) type true-time-delay (TTD) line for wideband high-resolution imaging radar applications.
