First Shared Project!
This is a simple 2-Tube breakout for socketed IN-12a nixie tubes. It is designed for each tube to be driven by a K1551D1 driver. The four inputs (A,B,C,D) of each driver is then routed to a SN74HC595N shift register. The Latch, Clear, Clock and Data pins of the 595 are externalized by pin connectors.
Input voltages are at the top of the board. 170 V, 5 V, and GND are expected. Please note that the 4th pin is not used. I also added resistors before the anodes of the tubes. At 170 V a 56K Ohm resistor should limit the current to 3 mA (.51 W, so use a 1 W resistor to be safe).
