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 ...

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 ...

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 ...

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

If you cultivate an interest in building radios it’s likely that you’ll at some point make a simple receiver. Perhaps a ...

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 ...

The circuit in this Design Ideauses a simple comparator circuitto make a power-on time delay for anautomotive rearview camera. Automanufacturers typically power reverse-viewcameras from the ...

This file type includes high resolution graphics and schematics when applicable. In some situations, it becomes necessary to drive a MOSFET (or IGBT) with a voltage that’s lower than its ...

The fruit fly brain has long been used to study how neural circuits self-assemble. Credit: Hiesinger et al. / Cell 2005 Think the rat’s nest of cables under your desk is bad? Try keeping the trillions ...
