analog regulator would be a slam-dunk level 4 solution.

But surely it doesn't matter David? There is nothing critical in
there, it's just a display. As long as the voltage is within the
processor's operating window, that is surely good enough?

It is between four and five Yuan. Four Yuan at the local market will buy
what four dollars will buy in the US (as long as you are not
buying imported goods).

You forget that this "Fluke.L" guy's first design replaced three
diodes with wire jumpers to save the cost of three diodes. The
builder is cheap beyond all reason. To a guy who'd replace diodes
with wire $0.78 must seem like a fortune.
I'd use a 3.3 volt reg also but in China 78 cents is what?

Because a real regulator costs more than 3 diodes and when you already have a
5V regulator, the 3 diodes work fine.
