Step 3The Right Stuff:
The muscle:
Searching on ebay I can across a dynamo charger made for black berry cellphone. The Dynamo chargers cost 5 dollars shipping included (Ebay's seller info :Elec.expert)
The brains:
On a local trip to TJ max I ran across a Griffin USB charger and bought it for this project. This item has great body lines and is very small, that is what sold me on this item . The Griffin Charger can also take a range of power input, so cranking does not have to be at a constant rate. You can use a 7805 Voltage regulator to do the same, but why reinvent the wheel if somebody has already built it for you?
