Yeah you could drive the counter with a frequency generator circuit or
something similar to display time. If it works I would try to preserve the
originality of the whole unit!
Showing time could readily be accomplished with an ESP, Arduino, or similar
for 10 bucks in hardware.

I doubt they will sell. If the asking price was low $200s or high $100s
with a best offer option, he could probably sell for $140-$170 a tube and
do so quickly.
He can take his $260 + shipping 7971s to the afterlife as far as I'm
concerned.

Maybe the high voltage supply is tapped out; just not enough current for
all 4 tubes at once. Or the high voltage is a bit low and causing
inconsistent ionization across tubes. It could also be a combination of
both where the power supply voltage drops when the tubes are brought up,
and the last
Talk about outrageous. Someone should lowball him. $400. Because that's
what it's actually worth (just the tubes).

That could be mercury condensate. I've seen it on a few JAN (mil

I would say the HV5530 is the best all around driver nixie IC. It comes in
a 44 lead quad flat pack or J lead plcc, the latter of which can be placed
in a plastic socket that is thru-hole soldered onto the board. It is driven
like a regular shift register (like the 74HC595). Shift in 32 bits, each

While inflation and supply (or lack thereof) are reasons for price
increases, a lot of it is a handful of sellers trying to fix the market
(especially with regards to recent 7971 auctions). Take a look at the 2
tube auction currently underway. 0 feedback seller, same 6 feedback bidders
as previous
I'm getting the impression that the same 3 people keep cooking their own
auctions on 7971s. Remember the 10 that sold in pairs on the display boards
late last year? Several auctions have popped up on what appear to be the
same tubes. Moreover, the same low feedback accounts keep bidding up every

The holding force is pretty snug. I think the 7971 has a pretty strong base
but it's always important to be careful and insert a tube with straight
pins slowly. I gyrate the tube slightly while gently inserting to give all
the pins a chance to line up. Then I push it straight in without worrying

I guess we'll find out how well this was implemented. From what I can tell
the pinout on the tube looks like a Male 1mm DIP arrangement with a
standard 2.54mm pitch.

I would be dubious about the 15 year warranty, but we'll see how responsive he

people who are into nixies are because they like nixie tubes and not because
they are out to scam people in a boutique market.

You can buy these smart sockets individually. They are pretty well

arduino.

If you're using IN8s I would suggest searching for some fine grid tubes; I

If I had to fix this, I would try taping the tube to a piece of wood and
knocking the wood against a hard surface. This way you can still transmit a
shock to the tube without directly smacking the glass.

Surely someone had to have discovered this, but it is just taken as fact in the
few references I find. Not that I'm doubting that mercury does indeed extend
tube life, but I have to wonder who first happened upon this.
I've seen references and claims to this fact, but never an explanation of the
