I know it is not but it looks like a soviet bomb.
Good job people.
-
Great job. The only thing I would suggest is to frost or paint the clear plexiglass so that you can't see the wires. other than that, this is 100% cool.

But will it blend?

@SunsetRon Big help thanks. What level of skill in solder do I need to have?

These nixie tubes are IN12 russian and for those who want to make a similar clock, minus the ring of neons, you can buy the pre programmed Atmel 40 pin chip from ALL SPECTRUM electronics. It's not a kit just the chip along with the easy to follow schematics; I have made about a dozen of these in both 4 digit and 6 digit time. The chip cost about $15.00, six tubes $5.00 each all other related electronics, another $20.00. It took me about 15 hours to make my first one.

The board is a custom build. It has a 40 pin atmel and 10 ttl chips for the twisted ring counter logic. Each neon is buffered through MPSA42 xistors. Has a 1F supercap for time backup to 18 hours. Also has a temperature compensated Xoscillator with software time correction making accurate to less than 1 second per year. There are 1400 jumper wires connecting everything together on a solderable perf board. PS for low level logic is a lambda switcher and there is a custom high voltage supply
