Yes I can, but there are no schematics, I've directly developed PCB. So I can post gerber files for it. It uses 16F887A chip, DS3231 for timekeeping, UC3843 with external mosfet for HV generation and also there are 30 pieces of MPSA42 transistors, which drive nixie tubes. Here how assembled PCB looks. (16F887 not installed in socket).
