Simple shorts sniffer
Recently, frequent and favorite contributor Nick Cornford gave us a cool and novel acoustic-interface design for a super sub-ohmmeter capable of audibly sniffing out defects in PWBs: “Tuneful track-tracing.” Figure 1’s design shamelessly nicks Cornford’s concept. It stretches the resistance sensing range by a few decades, thus spanning single-digit milliohms to double-digit ohms. This adds […]

Bluetooth Privacy Risks Grow as Denmark Issues Government Ban
The Challenges with Bluetooth Bluetooth has been a fantastic technology for devices across many industrial sectors, ranging from consumer products that love it thanks to its ease of use, ability to connect devices like headphones and speakers, to industrial systems that use it for low-power communication during initial setup of devices. Furthermore, its use as […]
Earthing Systems and IEC Classification Explained
Earthing (grounding) systems are a fundamental part of low‑voltage electrical installations, directly influencing fault current paths, touch voltages and the speed and reliability of protective device operation. They determine whether an insulation failure results in a quick protective trip or a dangerous shock hazard. This article explains the IEC 60364 earthing arrangement notation, compares TN‑C, […]

Probing a USB analog audio adapter
How do engineers squeeze all the necessary circuitry (and what is it?) into one of these devices, and do so this inexpensively? With the demise of analog audio line out, headphone (output-only), and headset (adding mic-in) jacks in modern electronics devices—computers, smartphones, tablets, and the like—alternative methods of connecting analog audio sources and destinations are […]

Bourns Unveils High Volt GDT for High‑Energy Surge Protection
Bourns has introduced the GDT225HE Series, a new family of high voltage, high energy gas discharge tubes (GDTs) designed for demanding surge protection in power and energy systems. These GDT circuit protection components target lightning‑prone, high energy environments where conventional protection elements alone may not provide sufficient robustness. The series combines high surge current ratings […]
