The main aim of this project is to design and construct a touch powered by shaking. A renewable energy flashlight comprises a housing and a barrel located within the housing. A wire coils wraps around the barrel, between the barrel and the housing. A magnet oscillates within the barrel when the touch light is shaken, generating an alternating current in the coil. Two spring at either end of the barrel causes the magnet to recoil when the magnet strikes the springs. An electronics assembly within the housing includes a capacitor for storing charge, a rectifier connected to the capacitor, and means for conducting current flowing in the coil to the rectifier, to charge the capacitor. A LED is connected to the capacitor by means of a switch, and lights up when the switch is turned on. This torch will be mostly needed in the rural area where there is scarcity of Electricity and because its cheap for them to purchase.
