It perhaps the old story it is difficult for
non-continental Americans have opportunities to
buy valuable time-nuts equipment such as e.g.
Hewlett Packard Vintage Digital Clock Model 115BR-HO8 seen on ebay recently
To temporary cheer up (?) myself I found (and
bought) available on local (European) market nice
COPAL flip-clock with witch is identical to that
one shown on an ended ebay auction
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=230590647002+
I refer to only for purpose of image of the
clock, so please forgive me link to auction on ebay.com
As the clock mentioned above has very nice
seconds dial I revisited outstanding pages:
http://www.leapsecond.com/pages/atomic-nixie/
Well it is nice solution presented, but I would
like ask you what would be from time-nuts
perspective simple (the simplest ?) solution to
drive such 50/60 Hz clocks without to much
overweighed stuff (and of course without
modifying the clock itself addig e.g step motor etc, etc).
As an overweight I would consider driving from
industry function/arbitrary generators and nice
but pretty rare and expensive on European market HP 6827A.
Let us suppose I have Thunderbolt (I really have
one) as a time/frequency source, but any other
time-nuts recognized frequency source should by
sufficient for the fun to drive old 50/60Hz stuff
with the highest precision available (and for
fun, comparable to www.leapsecond.com solution,
modulo cesium/hydrogen clock). It would be very
nice to see correction for leap seconds as well :-) :-)

Cezary
