Never, but based on my ebay experience (about 10 years of regular buying

There are a few issues with paralleling supplies that are not explicitly
designed for that mode of operation.
Imagine you have two voltage sources in parallel. The smallest difference
between the two would cause current to flow from the higher source to the
lower source. Depending on the control

I feel like PIRs are a must on most nix clocks. Why burn up tubes when no

For older stuff that doesn't have PIR compatability built in, you can

Hi all,
Since discovering the joy of nixie tubes a few years ago, I have learned a

kits and from scratch.

product, or briefly discussing what a

I've seen similar partial illumination on other tubes like 8971s. I think
that could be more than cathode poisoning, possibly outgassing. Hard to
tell unless you try reviving the tube with higher than normal current.
For over $3K USD it ought to be flawless.

ground would typically be around 80. These devices are overkill as far as
voltage goes but again, they replace so many components it's almost a no
brainer. Unless of course you want the aesthetic of 60 transistors on your
board.

I've been using a few of the microchip high voltage serial to parallel
converters in a number of projects. They are great and reduce component
count significantly.
Here are some of the major differences with the devices I've used for nixie
applications.
All the following are 32 bit (controlling
Hi all,
I have a friend that is looking to purchase a few ZM1350's. I know PV's
stash dried up recently. He is prepared to make very fair offers.
If anyone wants to turn some stock into $$$ please PM me.
Thanks,
Kevin

I get the impression the guy has no idea what it is. Just googled nixie
tubes and thought they were hot and all worth $$$.

Awesome work Mahdi. Those are some huge boards to mount up all the tubes in
one row. Must be nice to just sit there and admire the glow. Did you do
your own high voltage power supply?

The item description is equally ridiculous.

For that price he better guarantee it works! I understand the premise of a
market economy but that price is simply greedy.

You could add an MPSA42 for each extra decimal point. Or use a chip with
more outputs like any of the Microchip HV series (5522,5530,5523, etc).

If you are concerned about corroding contacts, I think a spartan amount of
conductive electrical grease would suffice to them safe from the elements.
Conformal coat can get messy very quickly. Plus, if you ever wanted to
replace a tube it might be even more of a bear as things might get stuck.
Thank you Jon. It's a labor of love!

The extra board is an NRF24L01 dongle. I plan to use this radio for
wireless accessories planned for the future, such as a motion sensor and
remote control for the menu system. Since the ESP32 has WiFi/Bluetooth on
board, the microcontroller's internal radio will be used for getting NTP to

Mahdi,
Initial post with details and schematics is here:

Mahdi, I've been working on the software but I can put up a draft about my
progress with schematics and board layouts. I'll share the link here as
soon as it is up!

Thank you! I like your custom zm1350 designs as well. Took some inspiration
from here and there to fuel the creative process.
