😏 This project I had made as part of my college science exhibition.In this ,with a pen I have attached a DC motor at the top on top of motor there is a fan attached and two battery cells are attached to it by connecting the wires to them,and then at the tip of pen there is an LED light and there is a on and off button to it so whenever the electricity goes you can just take that pen switch on the fan an light and do your studies sincerely.#-Link-Snipped-#
