DIY wind-powered cellphone charger
۱۶-year-old Thomas from Poland has created a device that uses wind energy produced by a simple bike ride to generate the necessary power to charge a cellphone. In his Instructables page, Thomas shared the step-by-step on how to assemble the portable wind-powered charger. This simple and ingenious device, that anyone with basic electronics knowledge can put together, lets you save energy and money, using your bike trip to charge your Smartphone, tablet or camera.
The base component of this device is an old CPU fan which can be obtained at little or no cost. This fan works as a wind turbine that converts the kinetic energy of wind into mechanical energy.
