DIY Hand Crank Generator Using DC Motor – Real-Time Voltage & Current Display


In this video, we demonstrate how to make a simple yet effective hand crank generator using a DC gear motor. This homemade generator produces electricity just by manually rotating the shaft. It’s a great science project for students and also serves as an alternative power source for small devices.

We used a DC gear motor as the main component for generating electricity. When the motor shaft is turned by hand, it converts mechanical energy into electrical energy. This generated power is displayed in real-time using a digital volt-amp meter, which shows both voltage and current readings.

To make the setup more user-friendly, we added a toggle switch for easy control. The wires are neatly arranged and color-coded for clarity. The motor is mounted in a way that makes it easy to rotate by hand, ensuring smooth operation during demonstration.

As you’ll see in the video, turning the shaft immediately generates power, which is visible on the digital meter. This proves the generator is working efficiently and can be used practically to power small electronic components.

This project is perfect for school science fairs, DIY enthusiasts, and anyone who wants to understand the basic concept of electricity generation. It’s low-cost, educational, and made using easily available materials at home.
