Delays to PCB production almost never first arise during the factory processing stage. Hidden risks that slow down progress are already planted weeks earlier in CAD files, in small details that no one stopped to examine closely. A typical process often unfolds like this: Your circuit design passes simulation tests, …

Here's the thing nobody tells you before a company relocation: the address change is actually the easy part. What catches most businesses off guard is everything else, the ripple effect on planning, people, and yes, your budget. Whether you're a CFO trying to protect the bottom line or an HR …

The ESP32-S3 is one of Espressif's most capable microcontrollers, combining Wi-Fi, Bluetooth Low Energy, USB support, a large number of GPIO pins, and hardware intended for signal-processing and AI workloads. However, taking full advantage of the ESP32-S3 requires understanding which GPIO pins are available and which pins have special functions. …
Read More »PID Tuning Calculator: Calculate Kp, Ki and Kd
PID tuning can be one of the most difficult parts of building a feedback control system. Even when your PID code is correct, the controller will not perform well until the proportional, integral, and derivative gains are properly adjusted. This PID tuning calculator uses the classic Ziegler-Nichols closed-loop method to …

Have you ever connected to Wi-Fi at a hotel, airport, or coffee shop and had a webpage automatically appear? That webpage is called a captive portal. Captive portals are normally used for perfectly sensible things such as accepting terms of service, entering login credentials, or configuring an IoT device. We're …

Becoming proficient with systems models is much like mastering any technical skill. Formal training delivers the raw knowledge. Active practice, guided by an expert, helps you turn that knowledge into competency. And a mentor who can course-correct your earliest forays, and help you identify priorities, is invaluable.
Read More »10 Network Performance Problems IT Teams Should Detect Early
When payroll stalls, a video call starts breaking up, or a cloud application takes several seconds to respond, users usually describe the problem in simple terms: “the network is slow.” For IT teams, the real challenge is determining what that complaint actually means before a small problem becomes a larger …

We are done with a few basics on PIC microcontrollers. Now it's time to learn how to load a program to the device itself. There are, in fact, plenty of circuits that can load a HEX file to a PIC microcontroller. Older programmers used the classical RS-232 and parallel ports, while …

The ESP32-S3 Mini, often sold as the ESP32-S3 Super Mini, packs a surprisingly powerful ESP32-S3 microcontroller into a board only slightly larger than its USB-C connector. Despite its size, the board gives you a dual-core processor, Wi-Fi, Bluetooth Low Energy, native USB, PSRAM on some versions, and enough GPIO pins …
