How creative are you when you make your circuit boards? Do you hunt around for different materials to use for the board? As long as it’s an insulator and can handle the heat of a soldering iron, then ...

A simple and convenient way to interface 2 relays for switching application in your project. This relay driver boosts the input impedance with a regular BC547 NPN transistor (or equivalent). Very ...

Almost every electronic device you've ever held in your hand has some sort of printed circuit board (PCB) in it. PCBs are an essential part of modern technology, but they're a little inflexible, ...

Anyone who’s spent significant amounts of time salvaging old electronics has probably wished there were a way to take apart a circuit board without desoldering it. [Zeyu Yan] et al seem to have had ...

Tossed circuit boards are about 20% copper, a much larger fraction than the roughly half a percent in copper ore mined from the ground. That percentage, plus the growing mounds of global electronic ...

Looking to cut down on the electronic waste produced by traditional printed circuit boards (PCBs), engineers from the University of Glasgow and Jiva Materials are collaborating to develop more ...
