[Stephen Woodward] is familiar with digital potentiometers but is also familiar with their limitations. That spurred him to create the PWMPot which performs a similar function, but with better ...

I'm trying to dim LED strips, approximately 30ft in length, with hand controls. I've found that regular potentiometers (those sold by Adafruit) max out at about 0.2 W. For whatever reason, the Red ...

The circuit described here is a switching 12-V, 10-A power supply whose topology is that of a conventional single-switch forward converter (Fig. 1). To derive the pulse-width modulation for its switch ...
