I have a bicycle trailer that has a dynohub, it generates from 6v 1a to 12v1a depending how fast I'm going.
So I want to make a charger for a smartfone that swicthes voltage to the fone itself rather than the usual other way round where the fone negotiates and requests a swtch in voltage, the other thing is traffic I will be starting and stopping a lot so the power willbe up and down a lot.
Is there any info available for adaptive charging, I;m sure an arduino would do the trick with the right info.
