OK, all of the obvious culprits have been ruled out so now we have to
consider weird things.
Wish you had a schematic, but it's not mandatory.
1. With your scope, do you see similar on/off times at the base of each NPN
'predriver' ? It should be in the milisecond range. Trying to rule-out the
Transistors arrived today --- I swapped in a new PNP and still no dice.
Since the tubes have individual anode resistors, I remain at a loss as to
what the problem is. Waveforms did not change.
On the working tubes, I can see the voltage drop across the anode resistor
as the tube lights. No suc

Hi
Maybe the seller bid on his own tubes with a different account to raise the
price and got greedy?
I never understood how people plan on making money on eBay if they only put 2
pictures...
There isn't even one where you see them working!

Hi Jonathan,
Thanks for sharing!
Jürgen's clocks (nixiekits.eu) use scrolling to switch between time and date. I
find it a nice feature since it uses the digits in the tubes more evenly in
addition to the anti cathode poisoning routine.
I like clocks with 2 "dots" for each separator column. Thi

Andy,
I don't know about that. I find it takes less effort to set a clock than it
takes to configure a network device. It also takes less effort to ensure that
you haven't crete a spambot if it's not connected to the Internet.
That said, I do believe in ntp for setting the time on our univers
This is not completely a firmware feature but a clock for this day and age
should be able to connect to my wifi, and then use ntp for time setting. A
challenge to make it easy for the user to set up since you have limited
display/input capability, but it could be as simple as allowing the user to

*Jonathan* - Are you running in an Arduino environment, or is the AT328
essentially standalone ?
I'm planning to switch to Arduino for my current/future projects, so this
is definitely something I'm interested in.
One thing I suggest is a 'scramble table' that allows you to handle

Hello Jonathan.
First of all, thank you for sharing your work.
While I grew up surrounded by RS232 cables, the serial setup sounds not
practical and user friendly.
In a couple of my firmwares I hardcoded DST changeovers for 100 years (eats
up 100 bytes): you only need to reset the clock at a know
Hi
I know a lot of people here have assembled kits or build there own clock.
For driving nixies there are not too many different ways. Since im more
"builder" than "programmer" i want to make a firmware thats really good,
and use the same firmware for all my future clock projects, so i don't n
