Dynamo charger for smartphone

The main purpose of this project is to create a renewable energy and apply it to charger devices. The renewable energy that been used in this project which is kinetic energy. When the bicycle in motion state, it will create a kinetic energy. Dining the process of kinetic energy, it takes the dynamo to spin and produce electricity. As the bicycle stop, it also stops the flow of current. The dynamo energy is attached at the tyre. The USB is the main output for charger smartphone. The charger is ON when the bicycle is moving. As the dynamo is attached at the bicycle, it can still supply the electricity even in a small amount of voltage. This project is quietly the same as the previous senior’s project. The main source is two dynamos. Both only can supply about 8V to 9V range from 12V. Both dynamo in turn each other to produce electricity from kinetic energy. The project aimed 5V fixed because this amount is suitable and not complex for a single smart phone.
