Depends on who's doing it.  Unless I'm much mistaken, the original inquirer
basically doesn't know anything about power supplies.  What's "simple"
(note that that's the word I used) for such a person isn't the same as
what's simple to somebody who designs switching regulators for fun. :-)
Yes, if you're willing to spend a little while learning about power-supply
design, it's no big deal -- but that's not the question that was asked.

While I have been accused of being an AI program, I deny that vigorously
vigorously vigorously [INFINITE LOOP DETECTED, RESET BEING PERFORMED...]
[Oops. :-)]  Really, I'm just me. :-)

As for why I'm here, I'm not a zoologist -- I run the computer facility here.
How that came to pass is a much longer story.
