You’ve got an apparently simple design requirement on your latest AC-line powered project: provide a distinctly illuminated indicator to show that the unit is plugged into the line and that power is “on,”...

What’s going on at Intel, the largest beneficiary of the U.S. push to onshore chip manufacturing?...
This design idea revisits another: “PWM power DAC incorporates an LM317”. Like the earlier circuit, this one implements a power DAC by integrating an LM317 positive regulator into a mostly passive PWM topology...
A previous article suggests that most digital output waveforms follow a nearly Gaussian profile. Let’s test that theory...
Capturing transient analog signals with a microcontroller normally involves adding a full-fat peak-hold circuit as an external peripheral. This novel approach minimizes that extra hardware by using a µP’s ability to switch its pins between analog and digital modes on the fly...
This design idea takes an unusual path to a power-handling DAC by merging an upside-down LM337 regulator with a simple (just one generic chip) PWM circuit to make a 20-V, 1-A current source...
Which step best approximates the digital signals you work with every day? The piecewise-linear step starts with a jerk, mindlessly follows a perfectly uniform ramp, and smacks hard into its upper limit. Real signals don’t do that...
The original application of the circuit was to locate coins, but it applies wherever you need to locate metal objects...
Vishay Intertechnology introduced two new IGBT and MOSFET drivers in the compact, high isolation stretched SO-6 package...
Toggle, slide, push-pull, push-push, tactile, rotary, etc. The list of available switch styles goes on and on...
