I one of those folks who knows enough to be dangerous. I have a good
grasp of a lot of basics, but I'm missing a fundamental piece that's
really important for a project I'm doing.
I've built a nice little FM transmitter kit which I'm putting in a nice
wooden case which will have an iPod dock on it. The transmitter works
great. It runs best on 12V.
The iPod will charge at 12V. This, of course, could be a really nice
way to both be broadcasting and charging at the same time. That's my
intention.
I see the iPod will take 12V on the firewire power connectors, and it
says "1A Max".
The basic piece of information I'm missing is: I want to supply ample
power to the iPod and transmitter. Do I need to worry about supplying
too many amps? Is amps just a measure of what the device will draw
and/or use? And how can I know how many amps the transmitter is using?
And I ask all this fearfully, knowing that I may not even be asking the
question correctly.
Can anyone help me understand this, or point me to someplace I can
figure this out?
Thanks much!
P.S. I already have some nice links to simple voltage regulators to
help know I'm getting the right voltage there.
