Driving Nixie Tubes is not a trivial task but I believe I have a good solution that needs to be turned into a HAT compatible with Raspberry Pi computers.

The project is to create a 4 or 6 digit Nixie HAT that is as simple to use as plugging it into the Pi and starting a simple Python program.

The project is heavily based on a modified Arduinix board that I used in my previous project - https://hackaday.io/project/16467-raspberry-pi-zero-nixie-clock

Schematics have been drawn and uploaded.

I am currently designing the PCB and will place an order to see if my design works.

    I have drawn up the schematics for V1 of the HAT. See them in the files section of this project.

    Currently the HAT is not official because it doesn't have EEPROM.

    I will add EEPROM and make this into official HAT when I have the basic functionality working.

    Up Next: drawing and ordering PCBs!
