The circuit was intended for monitoring and measuring the fluid level or content in a storage tank or reservoir by providing visual display with an audible alarm that can be switched. Light Emitting ...

A display decoder is used to convert a BCD or a binary code into a 7 segment code used to operate a 7 segment LED display. Here we design a simple display decoder circuit using logic gates. A display ...

[Hales] has been on a mission for a while to make his own diodes and put them to use and now he’s succeeded with diodes made of sodium bicarbonate and water, aluminum tape and soldered copper. By ...

KENOSHA, Wis. — Snap-on Tools, a subsidiary of Snap-on Inc., has debuted the Digital Display Circuit Tester (EECT400), designed to take the guesswork out of voltage readings, the company said. The new ...

Snap-on’s Digital Display Circuit Tester (EECT400) is designed to detect voltage, ground and circuit integrity. An LCD display provides the circuit’s voltage value, while a backlit LED indicates red ...

For those needing a method to capture a light pulse and even color, the circuit in the figure may offer a solution—without investing hundreds of dollars. Although typically employed as a display, an ...

In circuit development and testing, it's often necessary to display more channels than today's oscilloscopes provide. One simple solution is to trigger several oscilloscopes in parallel. However, a ...
