[time-nuts] Re: Long Duration elapsed time display

[Dana Whitlow]

Does it need to run off internal batteries on a single charge?  Or  is it
OK for it to require
AC line power?

How about a cheap old smartphone with a stopwatch app installed, powered
from a
wallwart USB charger.  This should keep running despite power failures,
provided they
don't last too long.
