Performance under transient loads has become the most important specification of voltage regulators used to power a wide array of products whose current demands vary quickly during operation. Testing ...

Combining Cor Van Rij's JFET test socket with two DMMs, a current limiter, switches and a wall wart yield a simple, accurate ...

Snap-on’s Digital Display Circuit Tester (EECT400) is designed to detect voltage, ground and circuit integrity. An LCD display provides the circuit’s voltage value, while a backlit LED indicates red ...

This simple circuit tests speakers, microphones, transformers and voltage. It’s basically a very low frequency oscillator that produces extremely short ‘fruity’ pulses. The type of sound produced is ...

Many tools can be used either for good or for evil — it just depends on the person flipping the switch. (And their current level of mischievousness.) We’re giving [Callan] the benefit of the doubt ...

The newly cloud-connected Leviton Load Center features intelligent circuit breakers that you can control or monitor from your phone. Originally hailing from Troy, Ohio, Ry Crist is a writer, a ...
