This resource provides clear explanations of how switching regulators work and how voltage boosting is achieved efficiently ...

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 ...

Have you ever needed to power a 12-volt relay in a circuit but only had 6 or 9 volts available? This simple circuit will solve that problem. It allows 12-volt relays to be operated from 6 or 9 volts, ...

I will be talking about single-series (1sXp) cell configurations, for a simple reason – multiple-series configurations are not something I consider myself as having worked extensively with. The single ...

Lighting a string of LEDs at a constant brightness requires driving it with a regulated current. A boost converter is commonly used to step up the voltage to a level high enough to bias the LEDs on ...

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 ...

Using simple components such as oil, salt water, lipids and proteins, plus routine genetic engineering techniques, it is possible to create simple nanofluidic ...

This circuit was designed to meet a medical application’s requirement to drive a laser diode with reasonable precision and a minimum of components and footprint (the device is now in clinical trials).

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 ...
