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
Design a charge device that can fast charge just about any device that uses USB power using your own physical exertion, including smartphones, tablets and rechargeable lights.

deliverable&specifications
charge smartphone fast.

portable and reliable cellphone charging

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. =budget= =design=
