It's an IN-14.
I have a running version of this exact same circuit, I built into a
Christmas ornament, been running perfectly since I powered it on, on
December 23rd. I looked at my old files, and this is identical, and still
this one is acting buggy. I'll mess with it again tomorrow, and let

What is the purpose of the 330ohm resistor on the +5v of the 74141? I
thought maybe I've been using it wrong all along and popped open my copy of
the TTL cookbook.. Nope, nothing in there about current limiting the 74141.
Mike's right, give us a schematic. :)
While I was in the TTL cookbook, I hap
Got a schematic ? Am I hearing correctly, that your using the exact
same circuit ? In the past it worked, but now its acting flaky. Same
nixie tube type and everything ?
Did you read the pinout correctly last time, but get backwards this
time ? Usually the number advance clockwise as viewed from
The other problem is, some of them don't display at all. I know I have the
Anode correctly connected ( I can see the ceramic insulator at the base of
the pin, inside the bottle) the only digits that light up, are 2, 3, 6, and
7, but those should be 0, 1, 2, and 3. Pins are all connected properly

Using a Picaxe( takes program fine, so thats working) the HVPS is

working, it changes numbers at the right time, it just displays the
wrong numbers.

I second this suggestion. In my experience, the ebay "resolution center"
is awesome. It will get the immediate attention of a good seller that
hasn't gotten back to your attempts at contact.. and it will give you a
method for resolving issues with bad sellers. For example:

Grief! I haven't heard that for 30 years. Great man.
Littering. They all moved away.

Hi Everyone,
Just an update on my nixie offerings;

Some B7971s have 'smeared' nipples, consequently, the holes on my

It may well be correct
I was going to keep my mouth shut on this thread, but a las, I just had to
flog the dying horse once more ;).
No rose colored glasses here. Except for the PDP 8E in HS, I was fortunate
enough to cut my teeth on micros. The 6800 in fact using a derivative of MDOS.
I remember the pain quite well,
Laurence, I hear your frustration and disappointment. I hope you get
satisfaction from the seller.
I have seen these displays and been tempted, so thanks for the warnings.
