Infineon Technologies AG has introduced a 27 kW three-phase power supply unit (PSU) reference design for AI server racks and systems based on the OCP Open Rack V3 specification. The design supports 311 to 528 VAC input, reaches peak efficiency above 98% at 480 VAC and 50% load and provides a power density of 116…
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…
In the previous article, we covered how the I2S protocol works, from its three wires (BCLK, WS, SD) to the clock arithmetic that ties them together. We also looked at the one-bit delay that trips everyone up and the controller/target and transmitter/receiver roles. That’s the foundation for everything that follows. In case you could use…

The central test is whether a robot’s safeguards still protect people when the information they rely on is manipulated. Safety and security teams can begin by tracing the inputs behind each protective decision, challenging them, and revisiting the evidence as the robot changes. They can start with these five questions: What does each protective function…
If you’ve ever scrolled through an ESP32 datasheet, you’ve probably spotted the term I2S sitting among the peripherals. You might have reasonably assumed it was a typo for I2C. It isn’t. The “I2” in both names does stand for the same thing (Inter-Integrated Circuit), but that’s where the resemblance ends. I2C is a slow, addressable,…
Welcome to the Engineering Deep Dive: Highlights & Technical Questionnaire This collection outlines key engineering challenges on our Electro-tech-online forums across multiple domains—including power electronics, motor selection, PCB manufacturing rules, circuit simulation, and RF…
UM 3561 is an excellent Siren generator IC widely used in Toy applications and Surveillance systems to generate different tones. It a ROM (Read Only Memory) IC which can be operated in 2 pen cells and it functions normally down to 2.4 volts. Using only a few components, it is very easy to construct a…
