Circuit design for solar battery charger

Closed Paid on delivery

Hi there, we are working on a new solar battery charger for phones. The form factor of this charger will be unique, but the circuitry behind will largely mimic the many products that are already on the market.

The scope of work would include:

1) Component selection (there is a lot open source documentation on this, so this task shouldn't be too difficult).

2) Creating one functional (but ugly) prototype (+ mailing us a working prototype)

3) PCB layout

I'd like to communicate through skype calls and have you mail us a prototype. So ideally you'd be located in the U.S.A.
