BCD Nixie Module Project. Fran writes -
Old School Side Project: I wanted to create a universal BCD controlled nixie display driver that could be made into a simple module for any application. Here for demonstration I have breadboarded an automatic counting circuit with a 555 wild clock triggering a BCD output up/down counter to act as a driver for the separate high voltage transistor control/switching board and nixie display, with complete low voltage regulated and high voltage supplies. All vintage parts too. Enjoy!
