Have you ever needed to power a 12-volt relay in a circuit but only had 6 or 9 volts available? This simple circuit will solve that problem. It allows 12-volt relays to be operated from 6 or 9 volts, ...

With so much analog-circuit design being done by automated tools and circuit-performance analysis done with tools such as Spice, it may seem anachronistic to actually go through a basic circuit in ...

This simple 4093-based audio peak detector from December 2004 monitors music and turns on a small light when the sound gets ...

So, I'm pretty handy with a soldering iron to put together stuff, but I have little to know idea of how to go about figuring out how to build a circuit. I mean, I know what a resistor does, and a ...

AutomationDirect announces the release of a new White Paper, “Basic Pneumatic Circuits”, which discusses common pneumatic circuits that can be used alone or as building blocks in larger pneumatics ...
