If you have the book Electronic Counting Circuits by Dance, a lot of his
trigger tube counter circuits use Z700 U tubes. These are 4 lead trigger
tubes with the primer electrode for consistant firing even in darkness.
So if you want to build a trigger tube clock this may help. I have found

Hello Nixie friends,
Thanks for all your requests to the CD47 Nixie clock project.
I know I did not update my page since some years, but my (small) clock
production took away all my spare time.
To show you how far the project is here a short video:

I'll take two and a spare set of tubes, please.

Damn! Those tubes are MASSIVE, and so is their power usage!

Hi,
We're experimenting with making our own nixie tubes in our shop. I was
planning on making the cathode out of stainless steel, but was
wondering if anyone had any advice about the best material to use.
Would it be better to try to find something rare-earth coated, or
isn't it necessary?
Also, i
Well, isn't this a hoot? Nearly another month has passed with no
watch. Along with an ignored message here and and yet another ignored
email.
So much for David's website claim of warranty repairs, or a new watch
if unrepairable.
I'm sorry to post this on the list, but I'm a bit frustrated as he

As far as the best material goes, I don't know if I could answer that
one. I started experimenting by modifying existing Nixie tubes. I
took a few cheap Russian tubes and broke off the seal. I tried
replacing the neon penning mixture with Argon to change the color.
The biggest challenge I faced

This is a situation between you and David. There is no need to air
your issues here. No need to publicly disparage David and Cathode

Clearly I was worried about my watch.
Another member suggested I post a message here to see if I could get
some sort of response since email didn't produce any results.
I have no knowledge of his business nor what his workload is. My only

Terry, what other recourse does mort have than to post here? If he
wasn't getting responses from david, there's really nothing else he
could have done. I'm glad that his watch got shipped, but come on, as
he said, it seems there was not enough communication going on. I would

LOL.
I seem to remember nickel from somewhere, but I'm probably wrong.
Isn't it in a datasheet somewhere? Maybe some manufacturer has some
old internal memos/datasheets they wouldn't mind giving up nowadays if
you emailed them.

Nice clock! I assume that the tiny circuit board under the clock is a
big switching power supply.
No. Power supply here:

See you have the microwave detector on the front - is that working ok?
Yes, it alredy works.
Presume you're using the big SMPS for this?
No, the most power need the tubes. But the PSU is overdimensioned (of
course - you know Germans like it overdimensioned)

I used to do neon signs so I understand your problem of getting a low
enough pressure. For the best vacuum you need a backing pump and a
turbo pump, sometimes called a molecular transfer pump. Neither are
cheep. Of course neon tubes use a MUCH higher voltage.

I think that if I was going to go down the road of making homemade Nixies,
I'd contact the guy that wrote this:
