Simple Sound Processor presented here is an ultra-simple circuit module suitable for almost all basic electronics and microcontroller projects. For example, this module can be used as a front-end in ...

This below circuit is a easy handsfree telephone receiver system. This doesn’t have dialing circuit so, it’s not a total phone replacement circuit, but it’s just only a loudspeaker system (i.e, phone ...

When working around mains voltages, it can be useful to know whether a given circuit is live or not. While this can be done by direct connection with a multimeter, non-contact methods are available ...

When looking for things to write about, there is nothing we like to see more than well-documented schematics and code available for download. In the case of schematics, we realize that they can be a ...

We all carry supercomputers in our pockets and use dozens of electric gizmos every day but rarely stop to marvel at the magical act of flicking a switch. Use your ordinary conducting and extraordinary ...

A software tool and a systematic wet-lab procedure proven in practice are an advance in the design and construction of circuits made of DNA. Electronic circuits are found in almost everything from ...

Neural microcircuits consisting of a few neurons and their interconnections are small enough to be understood more completely than larger neural structures, whose complexity quickly becomes ...
