This is an electricity question so I figure someone here could help.
The new ipod, santa brought, no longer works with my old ipod dock. Apple has changed the pins and charging voltage of the new ipod so, while the old docks will play music, they won't charge your ipod while doing so.
My question is this. I figured I could resolder the pins, on my old dock, to correspond to the pins which charge the new one. The old ones were fire wire, and the new ones usb.
The main problem I see, would be that fire wire's output was 12v whilst usb is 5v. So if I resolder the pins, I need to first introduce a resistor into the circuit to lower the voltage. At least that is my idea. Granted, my understanding of electricity, is limited to the experiment set I bought at radio shack, for me and my daughter, a few months ago. Which has been a ton of fun by the way.
I know the other problem I am going to run into is amperage. The difference in amperage between the two. I am not sure what the difference is right now but I am digging to figure that out as well. I will post more as I figure it out but does any one have any preliminary suggestions to point me in the right direction.
So some initial questions:
Is it possible, using a resistor, to step down voltage from 12v to 5v?
Is it possible to step down the voltage as well as the amperage? Is it possible to step down the voltage while boosting the amperage?
Thanks for the help!
