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 ...

If you’ve ever tried to build a printed circuit board from home, you know how much of a pain it can be. There are buckets of acid to lug around, lots of waiting and frustration, and often times the ...

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, ...

Printed circuit board (PCB) was introduced as a replacement for bulky wiring circuits almost a century ago. Today, it’s the core of the electronics industry, supporting the latest designs like IoT, AI ...

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 ...
