biNixie clock - preview video

I have finally produced a working firmware for my own implementation of a two-digit clock using two Burroughs B5092 Nixie tubes from late 1960's. The biNixie Clock. It uses

• an Arduino clone,
• a lumos.sk high-voltage PSU,
• K155DI BCD decoders and
• a DS1307 RTC for timekeeping.

It works from 12Vdc. Each tube anode has an independent variable resistor to set luminosity.

I need to complete the circuit and firmware with a couple of (hidden) buttons to set the time and a proper wooden housing.

I will release the Arduino firmware after tiding up the code.
