Abstract/Artist Statement

Our project's purpose is to use a bicycle wheel as a power source for a 5V direct current (DC) USB output at 5+ mph. This device must have a rechargeable battery. It must be mobile,mountable, and able to withstand jolts and vibrations. It must display charge rates, be operable in most local weather conditions, and power a headlight while moving. We will have a live demonstration of our project, showing the power/charging ability of our device. The design of this power system consists of a dynamo, a rechargeable 9V battery, an Arduino microcontroller, and two voltage conversion /regulation circuits. An essential piece of our project is a bike dynamo. This device easily mounts onto a bicycle and converts the wheel movement into alternating current (AC) electric charge. With the addition of the rechargeable battery, the bike dynamo is a useful tool. Our circuit design first converts this voltage to 9V DC for charging the battery, and then to 5V DC for a USB port. We will also be purchasing equipment for weather protection and shock absorption.
