The simplest of fan-control schemes an on-off switch is simple but inefficient, because it provides more cooling than necessary most of the time. When The simplest of fan-control schemes — an on-off ...

Mechanical relays continue to enjoy a growing demand and so far can't be replaced by solid state relays (SSR). Compared to SSRs, the lower cost, contact resistance and the galvanic isolation of ...

The traditional way to control the output of multiple LEDs is to dedicate a pulse width modulation (PWM) controller to each LED and use the controller to transform the input voltage to a current that ...

Every day engineers design products that employ single-phase induction motors. Speed control of single-phase induction motors is desirable in most motor control applications since it not only provides ...

Doing more with less in electronics often means improving power density. One of the new areas garnering attention involves applying a variety of advanced modulation techniques, including PWM and space ...

[hedgehoginventions] wrote in to share a little modification he made to his video card in order to keep it from overheating during strenuous 3D tasks. Having swapped out the stock cooler on his Nvidia ...

However, not all innovations are equal and nor do they follow a constant upward trend. Instead, their evolution takes the form of an S-shaped curve that reflects their typical lifecycle from early ...

In this session of Logic Noise, we’ll be playing around with the voltage-controlled oscillator from a 4046 phase-locked loop chip, and using it to make “musical” pitches. It’s a lot of bang for the ...
