Acromag has released the XVME-6800 6U VMEbus single board computer for embedded systems in defense, aerospace, scientific research, industrial manufacturing and transportation applications. The board uses Intel’s 11th Generation Tiger Lake-H Xeon® W processor with 32GB DDR4 ECC memory, NVMe solid-state storage, dual gigabit Ethernet on the front panel and backplane, USB, serial, video, audio,…
In this project, we’ll build a “smart” restroom door system using PNP and NPN transistors, where simple switching logic replaces software. The design avoids apps and Wi-Fi and instead relies on solid engineering fundamentals. The aim is to design a low-cost, fail-safe solution that detects occupancy, controls indicators, and automates utilities with minimal components. Let’s…
This tutorial series covers embedded system design using MicroPython and the NodeMCU development board. Throughout the series, you’ll learn embedded programming with MicroPython, along with how to interface different I/O devices, sensors, actuators, and other components with the NodeMCU board. In the previous tutorial, we learned how to interface analog sensors with NodeMCU, including potentiometers,…

Artificial intelligence (AI) is already in production use across electronics design and manufacturing, but its maturity varies widely by application. Machine-vision inspection and design-optimization tools do reliable production work today, while many newer generative and agentic tools still need close review from experienced engineers. The variation matters because AI isn’t one technology. The type of…
