I have a project in mind where I put a Pi into an old radio along a small amp (e.g.), or similar. The only problem is I'd like to only have one power lead to the whole thing.
The amp takes a 12V input lead, and while I see it's possible to power the Pi with 12V, is it advisable in this case to power both from the same source? Even if it is, would it have a significant effect on audio quality if I did? Is all of this a terrible idea and should I be doing it another way?
