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 ...

Every now and then a remote control acts up. Maybe you are trying to change the channel on your television and it’s just not working. A quick way to determine if the remote control is still working is ...

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 ...

The versatile phase-locked loop (PLL) allows multiplication of a reference frequency with an operating frequency that ranges from “DC to daylight.” A PLL is overkill for some applications, however, ...

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 ...

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 relatively simple circuit invented by researchers at the University of Texas could let smartphones and other wireless devices send and receive data twice as fast as they do now. This circuit could ...
