Nixie clock, Z5730m tubes

Hi,I started this project because I always wanted a nixie clock, I'm a HAM radio operator and in June I visit a flea market and it was there where I found a old circuit board with 10 nixie tubes, 8 times numerical and 2 alpha numerical.This was a cheap buy, I paid 15€ for the whole lot.Now the challenge to find the hardware and software, been looking at several projects I came by this posting, https://www.hackster.io/whitebank/make-nixie-clock-with-arduino-in-mdf-wood-case-3ef66d

For me this was the way to go.Testing the nixie tubes,

Making a test circuit on a breadboard,

Starting to develop a circuit board for the Z5730m tubes, had to do it from scratch no libraries available.

Testing the nixie tube board,

Next was developing the driver board I planed to place the boards in a small housing.

I own a 2D milling machine, I use it for outline milling circuit boards.

Next make a dummy housing in order to see if my plan could be workable.

Developing the housing, using triplex 3mm thickness.

The 6x nixie tube holes are milled with my home-brewed Proxxon MF70 CNC machine.

Testing the housing, if all fits properly.

Next challenge, painting the housing full gloss black.It took me more than 8 layers of primer and black paint!

Insert the boards and nixie tubes.

The end result was super.
