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…
This project is a Light gradient sensitive Robot with Solar charging capabilities, in other words it seeks out the light to charge itself. It accomplishes this behavior with a set of Four Light sensitive Photo Resistors in voltage divider circuits. The Arduino unit reads the four values which correspond to the intensity of the light received by the sensors through its analog read pins. It then applies a high voltage across a reed switch which completes a circuit between a 9v battery, and two Toy Motors, resulting in turning or moving towards the light.These motors were not able to be activated directly with the Arduino, if you get small enough motors, the switching portion of this project may be omitted without loss of functionality. If any of the four Photodiodes is registering much higher than the others, it detects which Photodiode is receiving the heightened signal and turns or moves in that direction for as long as the heightened signal is being received.
As its name suggests, long-range wide-area network or LoRaWAN technology is widely used for long-range, low-power communication in Internet-of-things (IoT) applications. In this article, we’ll guide you through the process of connecting an SX130x 868M LoRaWAN Gateway Module to a Raspberry Pi 4 using hardware attached on top (HAT). This setup creates a LoRaWAN gateway,…

The MLCCs are available in C0G (NP0), X5R, X6S, X7R, X8G, and X8R…
Smartwatches are popular wearable devices that are divided into two broad categories: phone companions and fitness trackers. The phone companion acts as an extension or mini clone of the wearer’s smartphone, staying connected via Bluetooth. Common features include email notifications, calling, messaging, social media integration, calendar management, music control, mobile payments, and voice assistant functionality. While certain…
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…
Smart technology refers to devices and systems that use advanced computing, connectivity, and data analytics to enhance functionality and efficiency. Devices such as smartphones, watches, and appliances connect to the Internet and one another via the Internet of Things (IoT), allowing for real-time data exchange and remote control. One innovative application of this technology is…
