Zitt, that sounds like a fun project.
I have only looked at your schematic for a few minutes, so I may not
completely know what is going on.
The first this I see that I do not understand is here I see the opto
isolator. As I understand it, you are planning on running the leds
through it.

You could maybe regulate the nixie current (instead of using LEDs) so
the active display is brighter than the inactive one.
Hadn't considered. Truth be told; I saw the LED back lit clocks and
basically thought it was a cool idea.
Maybe I'll do that on Rev2.

I do not believe anybody has suggested 50/50 copper sulphate/table salt yet.
For my first try, I was going to try a concentrated solution of ferric
chloride and voltage with stainless as the anode and cathode.
I do not know how it will come out.
I'll also go grab some copper sulphate to give
Ahh, found some nitric acid.
The 6 molar solution should do nicely.

Well I have a BFA dual majors in Ceramics and Printmaking. I can't ever
remember any of my friends having discussions about circles striving to be
squares etc. For the most part we were normal people and not pretentious
at all, of course we were in Ada Ohio, far away from the big city art
scenes.
Hi,
Is it a kf-16 to threaded hole connection? Send me photos and description,
I am making some parts for my system currently, so I could make that for
You.
