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 ...

Testing relays and their circuits in vehicles doesn’t always require a trip to the bench. With a few simple tools and ...

Andy recommends favorite resources for basic op amp circuits and includes a portion of TI's AN-20. Test your knowledge with ...

That circuit, which consists of three neurons and their feedback projections, has a simple task: to detect motion in the chicken's field of view.

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. The circuit ...

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

The circuit is a simple transimpedance amplifier that converts the device under test’s (DUT’s) IDS into an output voltage (Fig. 1). O p-amp U1A maintains the DUT’s source voltage at 0 V.

The solution is simple – either connect a charger externally, or short-circuit the OUT- and B- with something metal (I often add an external button), but it’s annoying to deal with.

Figure 1 Simple circuit to indicate a low battery. For this application, the LED proved to be a decent reference diode. It has a temperature coefficient that tracks fairly well with that of Q1, and ...
