The project presented here is a dual AC to DC output linear power supply. This power supply provides low ripple low noise DC regulated output. Usually, transformer-based linear power supplies are considered very bulky and inefficient, but this power supply still is very important for...

This is an Infrared Remote controlled motorized potentiometer controller. It's an open-source project built on the Arduino platform and compatible with Arduino IDE for custom programming. The project consists ATMEGA328 microcontroller, IR sensor, L293D motor driver, ALPS Motorized...

This is a complete microphone signal conditioning project. Designed primarily for voice-band applications, this project provides amplification, limiting, variable compression, and noise gate. User-adjustable compression ratio, noise gate threshold, and two different fixed gains...

The project described here is a high-efficiency dual BTL class-D audio amplifier with single supply operations. The project was built using TDA7491LP13TR from ST. The low profile PCB design can fit in a small area, operating power supply 9-12V DC, Project supports single-ended or...

The project described here outputs 12V DC voltage from the input of 230V AC. The output current is up to 100mA.  The project is based on BM2P129TF chip which is PWM method DC/DC converter with a built-in 650V MOSFET. BM2P129TF contributes to low power consumption by built-in a 650V...

This is easy to build and very useful project for hobbyists and students to learn and create OPAMP-based projects. The project accommodates a single OPAMP in the SOT23-5 package. The project provides the user with multiple choices and extensive flexibility for different applications...

This is Arduino compatible hardware that can control a single DC motor speed, direction, and brake using an RF remote control. The project is based on an ATMEGA328 microcontroller, H-Bridge DC motor driver chip LM18201, NRF24L01 RF module, 5V Regulator, 3.3V regulator and other...

This is an Arduino compatible open-source hardware that includes 1 x joystick, NRF24L01 RF module, Atmega328D microcontroller, 3.3V regulator, power LED, function LED, and other required components. This board can be used for the development of various applications such as Gaming,...
