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 ...

One of the problems encountered thus far with 3D-printing circuits with conductive filament is that it doesn’t really bond to anything, let alone solder, so how does one use it? [mikey77] wrote an ...

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 ...

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 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 ...

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 ...

Figure 1 gives a simple circuit for the PUSH ON, PUSH OFF function with only a few inexpensive components. In this design, the output is connected to the input of the gadget when you press the push ...

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

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 ...

An on-chip circuit that can produce up to six microwave photons simultaneously has been created by researchers in France and Germany. Gerbold Ménard and Ambroise Peugeot at the University of ...
