$1500 for 7.
You will find cheaper on ebay when they appear.
I'm interested in your project though.

Put me down for one kit too please.
Thank you, Michail

Just be aware that there is sometimes a startup issue with smartsockets. This
is something I have experienced myself and others have reported it also. This
results in a mangled display. Usually removing and restoring power will cure
the issue. Sometimes it might take a couple of tries. Once in o

I have 3, make an offer.

Tribute to the medical-evacuation mission, alternates between DUSTOFF and
MEDEVAC, various timers for keeping track of certain events. May add an
extra tube and add clock and weather functionality as well.

I think I see where you're going with this... Power up the smartsocket 5V
right to left? If the delay is too large won't the same thing happen?
Won't the tubes already turned on start the enumeration before the first
tube is ready? It seems like maybe the initial delay before starting the
enumera
Thanks Mike! That's a good idea; all about the little details right?

Does anyone have any leads (or is willing to sell) nixie tubes with smooth
tops? I am looking for tubes in the same form as IN-18 but want something
other than an IN-18.
I know about tubes like NL-900, NL-5440A, or B-5441A, but I haven't found
any listings for them in particular, would be open
Perhaps this is too obvious, but what about the ZM1040/ZM1042? Jens

Thanks, good point! I found a listing or two on ebay (though the ZM1042
there seem like it actually might be a ZM1040 with the orange washed off,
sparse results in any case). I'm might grab some, but I'd be interested in
sourcing some other tubes as well.

This is a stock clock with IN-18's. I have another set of these electronics

HI Nick,
I know you have mentioned that before, but I really don’t think anything
else is wrong. As I said I have another one of these with 566M tubes and it
has worked flawlessly for 8+ years. Those electronics are in a similar
enclosure with less ventilation. And this is the second set of el

I have one of these clocks too and it fails every three years or so on average.
It’s all down to C6. Sometimes just F1 fails and other times the inductor L1
goes short circuit as well.
The Equivalent Series Resistance (ESR) of C6 goes through the roof, causing it
to effectively be a capacitor in
There's a number of anomalies here. The 7805 has no reverse bias diode and no
100n output cap to prevent oscillation (read the data sheet). Is the 7805
running hot? Some 7805 variants require these, some don't.
R6 has about 180V across it - is it rated for that? There may be RF oscillation

You've described my experience with this clock to a "T". If I hadn't made a
custom enclosure around these electronics and its 'unique' tube spacing, I
would abandon it in a heartbeat and substitute NixiChron electronics, but
this would basically require building a whole new enclosure. It was my
Michael, I have to comment on the logic here.
You say you have one that is quite OK and seem to use that fact to rule out the
effects mentioned by Nick. Actually, I consider that the parasitic oscillations
