We’ve always been fascinated by things that perform complex electronic functions merely by virtue of their shapes. Waveguides come to mind, but so do active elements like filters made from nothing but ...

Have you ever looked at a small development board like an Arduino or an ESP8266 board and thought you’d like one with just a ...

In PCB design, design for manufacturing (DfM) is all about correcting mistakes after reviewing a PCB layout. We then devise corrective actions to fix those mistakes and improve procedures to make ...

When considering the long term reliability of a PCB, you must take into account the vias that you have on your board. While an invaluable and essential part of board design, vias introduce weaknesses ...

As the world is becoming increasingly virtual and software is replacing hardware, electrical and electronics engineers are trying to ride the same bandwagon with their tool of choice, PCB (Printed ...

Most circuits that require current loss detection use expensive isolation amplifiers. This circuit solves that problem with a simple and low-cost method to detect current loss of 4-20 mA. To view the ...

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 Design Idea in Figure 1 indicates a low-battery condition in an audio test instrument that is powered by four AA cells. As the instrument was otherwise an all-discrete design, this same approach ...
