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 ...

In many system applications, it becomes necessary to adjust a switched-mode power supply (SMPS) output voltage within narrow limits in order to remove tolerances and drops in the power path, verify ...

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 classic potentiometer (pot) has been used successfully in electronics system designs for decades: its strengths and weaknesses are very well understood. But what if the pot were able to be ...
