Am I likely to find a source of 12v inside a CD boombox?
I'm planning on building my own kitchen under-cabinet stereo using parts from an old boombox and a CD-ROM drive. I've been looking at 'ibles like this
for inspiration. I know that the CD-ROM drive will require both 5v and 12v input, and I don't expect to have much trouble finding 5v (or something higher I can drop down with a 7805). What I'm concerned about, though, is finding 12v.
Eventually I'll be poking around in there with a multimeter, but I was wondering if anyone can tell me if it's likely that the existing CD player in the boombox would have run on 12v, or something lower.
