It’s late at night. The solder smoke keeps getting in your tired eyes, but your project is nearly done. The main circuit is powered by your 13.8 V bench supply, but part of the circuit needs 9 V. You ...

The design of the project consists of a few simple electronic components to create a metronome device that can be used as an invaluable practice tool for musicians. The term metronome refers to ay ...

Many electronic projects require the use of a small audio amplifier. Be it a radio transceiver, a digital voice recorder, or an intercom, they all call for an audio amp that is small, cheap, and has ...

AMOEBAS are smarter than they look: their bodies can store rudimentary memories. Now a team of physicists has built a simple electronic circuit that behaves in a similar way. When amoebas are ...

This file type includes high resolution graphics and schematics. Rechargeable nickel-cadmium (NiCd) batteries are widely used in consumer electronics because of their high energy density, long life, ...

Amoebas are smarter than they look, and a team of US physicists think they know why. The group has built a simple electronic circuit that is capable of the same “intelligent” behaviour as Physarum, a ...

Biodegradable printed circuit boards are being tested for use in wireless communication technologies, through a collabora ...
