    Nixie-tube driver board for my nixie-clock. 2x PCF8574 8bit i2c I/O expanders and 4x K155NA1 russian SN74141 clones.
    Also transistors to drive 2 neon(glim)-lamps.

    Project folder on my server:
    http://ketturi.dy.fi/Galleria/main.php?cmd=album&var1=nixie-clock%2F&var2=

    Next AVR board and more coding. (I can't get RTC to work, tried 2 chips and rewiring everything on protoboard)
