Hey. Thanks for replying
Thanks Nigel for clearing up the concept on Alternators and Dynamos. So are bicycle "dynamos" in actual fact alternators or dynamos producing DC?
I do have knowledge on how alternators/dynamos work - concept on electromagnetic induction
and
Some other basic circuitry like resistors, semiconductor diodes (Wheatstone bridge), etc
I will break down what i exactly want to do in this DIY project
1) I would like to use dynamos/alternators (not sure which one to use yet) attached to the wheels of the bicycle to induce an emf
2) The voltage induced need to be used to charge a battery pack (Uncertain on which one to use - Li-Ion, Li-Poly, Alkaline)
3) The battery then needs to discharge to a USB Hub where there are multiple USB ports.
4) Appliances with the standard USB charging interface like mobile phones etc can be plugged into the USB ports to get charged
Its my first time doing something like this so i need help with details of components i will need. I can understand circuit drawings but i do need help in how to set this up and what i specifically need to get.
Thank you so much for your time
