Step 2The Options:
Options are good. Looking online there are many ways to build a dynamo charger. Some good and some bad. (very very bad) Here are some of the best options:
1) Dynamo charger plus an Any volt micro step up step down voltage regulator (picture below). On Ebay there are many windup chargers for prices as low as $2.50 shipped.
Advantage:Low cost and easy to buy. Micro Any volt is a great little circuit that can take 2.6-14 volts and step up/down to 2.6-14 volt output.
Disadvantage:Some are poorly made and have bad electronics.
2)Dynamo Charger plus 7805 voltage regulator.
Advantage: Cheap and easy to build.
Disadvantage: Excess electricity is made into heat and has to be dissipated with heat sink. (hot hands?) Have to build a 7805 regulating circuit. (Google 7805 voltage regulator for more information)
3)Dynamo Charger plus USB Car Charger
Advantage: Very easy to build, All parts can be bought locally. Two wire connection
Disadvantage: Cases have to be modified to accept each other
Option one is the best in my option, But due to back orders I was not able to build this model. In this instructable I will guild you to building the easiest of the options, Number 3 and hopefully post the others in a later edition.
