After a brief break, I found myself revisiting latching relays—not just as components, but as puzzles waiting to be solved.

Here’s a nostalgic vibe of an awesome analog chip from the 1990s era that’s still making an impact in audio designs.

The remote variable resistor functions as a voltage-controlled resistor whose resistance changes based on an applied voltage.

A software suite powering oscillators and clocks claims higher time synchronization accuracy than quartz-based solutions.

There are many options when you need to splice wires. In addition to formal two-piece connectors, there’s the widely used ...

A capacitor measured with a $100 handheld multi-meter can give a substantially different result than the same capacitor measured with a $10,000 LCR meter. That same capacitor measured with two ...

One of the issues that beginning electronic engineers must grasp is the concept of impedance and impedance matching, epically with respect to transmission lines, cables, and connectors. This FAQ ...

The first installment of this two-part series focused on debugging brushed-DC motor systems. Now the second installment will share some tips for stepper motor systems and provide general bench testing ...

The tips and tricks when testing motor-driver ICs on the lab bench can help engineers reduce time spent on evaluating and prototyping motor systems. The first installment of this two-part article ...

There is a lot of demand for the tiny speaker in smart glasses and smartwatches to be even smaller and lighter. However, the century-old micro-speakers built around a dynamic driver, coil, and ...

How does the circuit operate? It's simple: the input signal charges the hold capacitor, and the diode prevents the capacitor from discharging. The input op amp, in conjunction with the capacitor, ...
