Raspberry Pi Compute Module 4 has been one of the most popular hardware from the manufacturer with its ever-increasing carrier boards. Chinese embedded electronic device manufacturer Edatech has released a new industrial box, CM4 Nano, built around the Raspberry Pi Compute Module 4...

Espressif introduced the ESP32-C3-WROOM-02 system-on-chip past year with options between the onboard PCB antenna and the external antenna connector. Adafruit has taken the lead to unveil an ESP32-C3 based developer board supporting Wi-Fi and Bluetooth Low-Energy wireless communication....

Storage requires critical consideration when building a data management and network project, especially to manage unexpected network growth. This is the reason behind the Pintry-X2 - Network Attached Storage (NAS), released by hardware Engineer Cezar Chirila to help network engineers...

Introduction Quality of air in enclosed places, especially homes are in recent times, thankfully, becoming a prominent source of concern because of its severe health implications, and several home automation and safety companies are stepping up to the plate, developing smart and...

The stereo audio amplifier project shown here is capable of delivering typically 40W per channel continuous average output power into an 8Ω load with less than 0.1% (THD+N). The project is built using an LM4766 chip from Texas Instruments, The performance of the LM4766, utilizing its...

This is an under-speed sensor module that provides an audible warning and signals output when the speed of a machine is below the set point. The module can be used in applications such as Engines, Machines, Sports machines, Fitness Equipment, Speed of the machine or engine can be...

The project presented here is a low-cost solution to control high-power brushed DC motor speed and direction. Traditional DC motor controllers are based on solid-state circuitry known as H-Bridge. Here we have made an H-bridge configuration using high current 2 x relays which can handle...

The project presented here is a low-cost easy to use DC brushed motor direction controller with fast-brake, the project was built using two 12V Relays, 2 x BJT transistors, and 2 x tactile switches. The two LEDs are provided to display the motor direction, 2 tactile switch controls the...
