Ergonomic fast battery

=Project overview=

Background
Bicycle dynamos are nothing new, but charge-while-you-ride technology has improved by leaps and bounds in the last few years.These days you can charge just about any device that uses USB power using your own physical exertion, including smartphones, tablets and rechargeable lights.

Problem Statement
The intention of this project is to build a straight forward human powered generator from a used bicycle and use it to charge our phone. This project help us develop engineering skills while learning about a clean way of generating electricity.

Deliverable & Specifications
1.Charge smartphone fast.

2.Portable and reliable cel1phone charging

3.Ensure enough power and steady voltage.

Goals
designing a phone charge that uses power generated from the bicycle. A normal phone usually use 5V charge and a USB. So our goal is to able generate electricity from the bicycle that can give an out put of 5V by using a USB output. As a group project, we have pinpointed our design constraints, we divided the project as 3 parts: generator, DC-DC converter(to constant the variable input), battery. And we will focus on designing the DC-DC converter.

Current Regulator Testing
The dc-dc converter work as a current regulator to charge our capacitors. For this current regulator, an SPI slave port is provided to allow a host to configure its output limits and enables. So, we select using an Arduino to drive it, and we could get any voltage and current output in its working region. This is our coding loop,we communicate with the current regulator by arduino.
