Measuring dynamic currents with an oscilloscope is challenging, but this updated differential current probe makes it simple ...

With loudspeakers, an important parameter is the frequency at which their cones resonate. This clever Arduino-based tester ...

Benchtop EMC testing: why ferrites barely help, how to split common- vs differential-mode noise, and the two-inductor fix that works.

Almost all commercially available microphone amplifiers draw their power from a 48V phantom power supply. If this is unavailable or unsuitable, the solution is to build a self-powered amplifier.

Elektor’s book, Apple Macintosh, explores the machines that reshaped personal computing — from the 1984 original to today. Packed with photography and engineering insight by Giovanni Becattini, it’s a ...

ESP32-E22 Wi-Fi 6E is Espressif’s first tri-band Wi-Fi 6E co-processor, adding dual-mode Bluetooth and offloading protocol ...

Precision picoammeter webinar on picoamp current measurement, leakage and noise control, plus automated I–V sweeps with ...

Machine learning enables real-time PCB defect detection using a FOMO model on a Raspberry Pi. Learn how with this ...

Most PC “mic” inputs are pretty average for noise and distortion, and they’re usually mono. Plus, they can’t properly take balanced, pro microphones that often need 48-V phantom power. This ...

Why this is still worth your time: an oscilloscope is one of those tools where small misunderstandings compound into bad ...

HFM FPGA Module Standard arrives with solderable and connector variants, aiming to cut board redesign time and vendor lock-in ...
