This is a Nixie clock on processor PIC16F84. Tubes Z566M and Z567M were used in this project. The whole device is closed in wooden (oak) housing, which can be home made – glued and painted with varnish for parquet.
The clock works properly, it has a battery backup.
Scheme can be found at LINK. The clock was made on two PCBs connected together (header) and screwed by screws M3/20.
