A bit off-topic, and not really anything very original, but a nice small
project for a rainy Sunday afternoon to give your old meters a useful
second life.
Now here's an idea. Take one nixie based frequency counter and couple it
with a programmable frequency generator. Drive the generator by a micro such
that it generates frequencies in the correct sequence of steps to show the
time on the counter. If you used a 24 hour clock it would take the highest
frequency of 235.959MHz or 125.959MHz for a 12 hour clock. You could even
generate an overflow condition, causing the neon/led to light, as the am/pm
indicator, depending on the range of your nixie counter. What's more you
still have a working counter and sig gen when you need them. Just need to
set the gate time to 1s and set the display to hold.
