Introduction: Ultimate 10 Watt USB Bicycle Generator
This Instructable is on how to create an Ultimate 10 Watt USB bike generator system combining dynamo and solar energy! It combines my previous Instructables for Solar USB Charger and Bicycle Solar/Dynamo USB Charger + Tail Lights with a new SivaCycle Atom dynamo wheel generator :

Simply attach the SivaCycle Atom to the rear wheel and connect it to the solar rear rack. I had to remove the SivaCycle battery because it would not work in parallel with my Power Core battery. My Power Battery does a better job with managing power spikes up to 1.3 Amps to the storage battery and the ability to pass excess energy through to the USB device. I used a Charge Doctor that I bought off Adafruit to measure the power output - http://www.adafruit.com/products/1852
This combines .8 Amps from the SivaCycle Atom and up to 1.2 Amps from the solar panel at 5 Volts for a maximum of up to 10 Watts system output! This is great to create consistent energy while riding so that even when stopped at a stop light, the solar panel still generates energy and while riding under a dark tunnel or bridge, the dynamo still generates energy! Riding out in the sun will combine the energy of both generators for maximum output!
