Hi everyone, My name is Kevin, and I've recently developed a nixie obsession. This seems like the place to be for those who are obsessed with all kinds of glowing tubes! Also, I'm currently working on a project to make a 10 digit display from NL840 tubes, with dots and a plus/minus NL843 tube (primarily for a calculator). It is driven by four Microchip HV5530 serial to parallel converters and an arduino (12v to 3.3v logic level shifter of course). Here is a quick demo video I've made of testing the display (haven't quite figured out the software yet; first time!):
https://www.youtube.com/watch?v=468QV6E7rm4 Currently, I've found myself getting stumped with the software aspect of driving these four daisy chained HV chips. They are essentially 32 bit shift registers back to back, for a total of 128 bits. Some of the outputs are not used too, please see the pcb (I didn't make a traditional schematic). If anyone can see my bitbanging code that was used in the video (https://github.com/verrucktmechaniker/nixie-calculator/blob/master/bitbang_test) and my board layout image (https://postimg.cc/LnKstKLh) and make sense of how to control this, that would be awesome! I definitely plan on releasing this project as a step by step do-it-yourself once I get some help and figure out the software/control side of things!
