Cameras lie. Photos
Drat, and double drat. I was really hoping I had some defective tubes
here. they look pretty and purple in the dark, but not so much with the
lights on.
Oh well, I'll stick to neon, and nixies I guess!
Thanks!

There are neon-based regulator tubes available. However, the gas mixes varied
depending
If anyone is interested, I have (5) B7971 dual driver boards, the
Ultronics style, available for the nominal price of $25 plus shipping.
The sockets have been removed, but the rest of the components are
there.
As always, I'm open to trades.

Hi folks,
given the thoughts in a different threads, I was curious what techniques
you use to photograph Nixie tubes.
I am currently sick of my digicam, I am seriously thinking of purchasing
something real, along maybe with a light tent? Any ideas?
Looking forward to hearing your

As a hobbyist, would the Cortex chip be a good platform for learning. I
know everyone hypes the Arduino environment for beginners but I would prefer
to go with something different. I assume this MCU would not be overkill for
a nixie clock design? I know these are used in devices as the

Thanks Adam,
It seems that Stanislav Pechal's code is used by others as a starting point
for some of these clock designs. I appreciate the information and can learn
the basics. The code is pretty compact and has the basic features. The
display multiplexing was something I wanted to get a

As with many Nixie tubes, the sockets can be the hardest part to find.
Fortunately you can get pin receptacles that work fine, as do DB

My single piece of advise when choosing an AVR programmer is to make sure
that it is compatible with AVR Studio.
A cheap DASA programmer or the USBTiny are great programmers, don't get me
wrong.. But you're stuck dealing with them commandline from AVRdude.. I've
got better things to do
Hey can you email me pics, I'm potentially interested.
I'm doing a 7971 projects in the Ultronics style (i.e. lots of them as an
alphanumeric display) I'd love to see them up close and I love to buy stuff
like that.

Having spent some time photographing the IN-18 blue dot phenomenon I
can say that it is a matter of balancing the ambient (or flash) light
with the emitted light. If getting up close it is a good idea to
manually set a small aperture (high F number) and using a longer
exposure so the depth of
Just what exactly causes that phenomenon? I've had a few IN-18's over the

Lots of speculation on the blue dot.
I don't think anyone has come up with an absolutely answer. Just
guessing, etc.
I have sold hundreds of the IN-18. I used to consider the blue dot as
something I wanted to get rid of in my stock; however, I have changed my mind.
Now, I have about

Yes of course. There is only one right answer.
