Building a Wi-Fi Router Watchdog

Dev created a watchdog for a Wi-Fi extender using a Raspberry Pi Pico. This monitors Wi-Fi connectivity for his smart home lighting system, which would require a reset twice a year due to rapid power interruptions.

Holiday Hangover Hardware Hacking

Having too much cheer during the holidays? In this month's article, Colin offers a diversion from the jolly season by urging developers to retreat to the basement to brush up on hardware hacking skills. He shows how a low-cost Raspberry Pi Pico and a TP-Link Tapo C200 smart IP camera could become the next automated bird deterrent or a home automation server.

Performance Bottlenecks in Embedded Linux Solutions Analysis, Identification, and Mitigation

Good performance is a requirement for every technology, and system designers rely on operating systems to ensure fast and smooth transitions in critical applications. Fortunately, Pedro writes, the embedded Linux OS offers ways for finding, analyzing and mitigating performance bottlenecks so embedded systems can deliver the speed and efficiency that end users expect.

Datasheet: Microamps Per Megahertz Ultra-Low Power MCUs Minimize Current Consumption

How do chip makers differentiate if many ultra-low power MCUs on the market feature the same processor core? The peripherals and different power states offer various ways to manage current consumption down to microamps per megahertz.

Smart Home Lock Down Matter Provides Security Blanket

As more devices in the smart home connect to the Internet, they become increasingly vulnerable to outside attacks. Developers can now add the latest security measures to their Smart Home devices through Matter.

Basic Pulse Circuits

In part one of a three-part series, Wolfgang wrote how basic pulse circuits help digital circuits, such as embedded boards with ARM processors, deal with pulse trains or bursts of pulses from the outside. In Part 2, he dives into enabling flip-flops, timing parameters, and synchronization, design tasks needed to capture, detect, and filter pulses.

From Maxim's RS-232 to WeMos ESP32: So Much to Do, So Little Time

The Elite College Students Who Can't Read Books - To read a book in college, it helps to have read a book in high school.

Nicholas Dames has taught Literature Humanities, Columbia University's required greatbooks course, since 1988. He loves the job, but it has changed. Over the past decade, students have become overwhelmed by the reading, College kids have never read everything they're assigned, of course, but this feels different. Dames's students now seem bewildered by the thought of finishing multiple books a semester. His colleagues have noticed the same problem.
