Hi all, Group noob here, about to start build on a few different types of display using Nixie tubes and ESP32.
Planning to use K155ID1 initially (as I have a bunch) with some IN-12 and IN14 tubes but want to also try HV driver such as the 5812 or 5530 so would welcome any comment on which is the best one to go for or an alternative. I don't intend to multiplex. Any driver would need to be DIP or PLCC. Have spent many hours looking at the schematics and designs of others, I'm grasping the basics but one frustration and evident gap in my knowledge is how to pick / calculate the correct component and its size or rating for anything other than the most basic circuit. For example, with a 180v supply, calculating the anode resistor for a tube based on the datasheet is straight forward enough as the maintaining voltage and current are known. When looking at something like the HV5812, many seem to use a 60 or 70V zener diode with a resistor to keep below the max for the chip but how do you determine the current needed for the driver, diode and load to be able to calculate the current limiting resistor? The diode datasheet is simple enough but I'm lost with the sheet for the HV5812. Thanks. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
