With the increasing power requirements of Artificial Intelligence (AI) processors, server power supplies (PSUs) must deliver more and more power without exceeding the defined dimensions of the server racks. This is driven by a surge in energy demand for high-level GPUs, which could consume 2 kW or more per chip by the end of the…
The ESP32-CAM is a widely used development board for embedded vision applications. It combines the ESP32 microcontroller with an OV2620 camera module, and the ESP32 itself comes with built-in Wi-Fi and Bluetooth capabilities. Previously, we created a video streaming server using the ESP32-CAM to troubleshoot potential operational issues with the module. In this project, we’ll…
In the previous tutorials, we discussed two passive properties of electronic components, resistance and capacitance, and their electronic components, resistors and capacitors. Passive components are unable to generate energy, but can store or dissipate it. We’ve already learned about the electrical properties of resistors and capacitors, including how they affect the current and voltage in…

Toshiba TCWA1225G RF SPDT High-Power Antenna Switches feature Toshiba’s original CMOS process for RF transmission path switching circuits. The switches offer a high-power input and a single-pole, double-throw (SPDT) transmission path. The TCWA1225G series provides a built-in GPIO control interface for easily controllable switching. The switches are housed in a compact 1.9mm x 1.9mm WCSP…
Spy gadgets, once exclusive to professional espionage, are now widely accessible and affordable for everyday users. Today, such devices are commonly employed in personal security, surveillance, private investigations, and sting operations. They also serve practical personal needs, such as monitoring pets, children, or elderly family members, recording lectures and meetings, and documenting events. Various spy…
Additive manufacturing or 3D printing is more affordable than it’s ever been. Although some hobbyists buy a printer for crafts and to experiment with, it’s also an excellent engineering tool for innovative electronics or robotic projects. Typically, printers offer complimentary 3D models or free downloads that are ideal to start with. Eventually, you’ll likely want to…
Road safety is a critical concern, with driver fatigue and distractions among the leading causes of accidents. In this project, we’ll devise a smart system using Arduino UNO and a blink-eye sensor to monitor driver alertness. If the driver shows signs of drowsiness, the system takes proactive measures to prevent a potential accident. This includes…
