In this exciting DIY project, we’ve created a fully functional automatic machine gun prototype using simple household items and basic electronics. Whether you're into robotics, science models, or creative inventions – this video will inspire and guide you step by step.

The machine is built on a cardboard base, featuring two high-speed rotating wheels powered by DC motors. These wheels act as the firing mechanism, launching small objects (like paper balls or beads) at targets – in our case, a pyramid of paper cups.

We've used a gear motor for the ammo-feeding system, which automatically pushes projectiles into the spinning wheels. A push-button switch controls the mechanism, making it easy and fun to operate.

All the components – including the toggle switch, wires, battery, and motors – are connected cleanly to a simple circuit, allowing smooth and reliable operation. The build requires no advanced tools, making it a perfect project for students and hobbyists alike.

In the demo section, watch as the machine gun fires and knocks down a stacked tower of Nescafe paper cups! It's not only satisfying but a great example of motion, force, and mechanical design in action.
