Is this a clock that was already built and you have been modifying
for
lower current use? or is this a clock that you designed from the
ground-up for low current

the simplest, one-package
solution.
Am I wrong here? Am I missing something?

In an effort to build a low-current nixie clock,
I tried using all 74HC parts. That works great,
but there are still the (6) 7441, or 74141 TTL drivers.
How about this idea? When the clock is running on
the backup battery with no line power, what if 5 volts
Vcc were to be removed from the
10 matches
