A little demostration of my clock built around 4 soviet IN-14 Nixie tubes (found 5 in the local auction, but one of them was cracked :-(
Clock is made of an ATmega8535 MCU, 4 KM155ID1 IC's (soviet ceramic version of 74141). Software flashed in MCU is currently unfinished - it lacks setup mode and calendar... After power-up and reset it always counts from 12:00, 23 April 1982 =) Do you know what happened this day? =)
Clock is interrupt driven from 32768Hz watch crystal.

Maybe when I finish this project, I will post source code and PCB's somewhere.
Power supply schematic and PCB was taken from:
