Build a Simple Hand Crank Flashlight

Learn how to build your own hand cranked flashlight. This device incorporates a few ordinary components like a stepper motor, a crank mechanism and an integrated electronic voltage stabilizer circuit. Operating the crank mechanism by hand simply initiates the generation of electricity through the conversion of physical power first to a mechanical level. It is generated into electricity due to the action of the rotating copper winding within a magnetic field arranged inside the stepper motor. We've provided the entire circuit idea.
