Let’s be honest, commercially-available soldering fume extractors are cheap enough that you probably don’t need to build one yourself. But it still makes for a good starter project, especially if you ...

Withclosed loop speed control, the fan controller ensures that the fan isrunning at the desired speed by measuring the actual speed and adjustingthe duty cycle accordingly. Here the host specifies the ...

ROHM Electronics’ BD62xx Series of H-bridge driver ICs offers designers a simple upgrade path to PWM speed control using either analog or digital inputs. The drivers provide a TTL-compatible interface ...

San Diego, Calif.—ROHM Electronics has introduced an H-bridge driver IC line, offering designers a simple upgrade path to pulse-width modulation (PWM) speed control using either analog or digital ...

When implementing cooling solutions for electronic equipment, system designers are confronted with a complex set of variables. The cooling requirements are typically dynamic, and ambient temperatures ...

This post is a quick sequel of my previous article jam-packed with my personal experiences and observations while I was fiddling with standard 4-wire PC cooling fans. Today I will be talking about the ...
