P.s. Modern day "digital" clocks, at least the ones that derive their
operating power from a wall outlet, such as the clock radio on your
night stand for example, also use the mains power line frequency for
their time base. Ira.

Leaving aside the issue of how much accuracy you need, there are a few basic
strategies -
1. Find a good clock source that can be used to supply the CPU clock (1s to
10s of MHz).
2. Feed a high quality 32768Hz clock to your micro and use that as the
timebase.
3. Find some other time sou

I am in love with these tubes since I've seen them for the first time

If driven 1:6, you will notice a definite flicker if you squint and look

The situation has been this way for several months. Probably it is one

I have only 10 IV-4s that are my only hope to make my very own FLW.

I would not bother with the starting price. List a set of four at $USD 1

Hi,
I'd love to acquire some of the also-lovely CD66 nixies with the fine mesh

John, you might want to look for the Siemens ZM1242 as well, it is very
similar to the CD66.

Out curiosity, do you think that this zeal to purchase rare tubes extends

Hi folks,
I also do not like the digits of the CD47 so much. They are somewhat
special, of course, but personally I like the digits of the British
GR10-series best, i.e. GR10G, GR10J and GR10J/F. It is a shame they were
only made with 3cm digit height.
Then again, the F9020(AA) has quite nic
