However, that's not what you want to do, so: The slight problem I see with the chips you have is that they have negated BCD outputs. You'll have to get some TTL NOT gates (e.g. 7404). Unless you want to go "full-retro" I'd use some opto-isolators for driving the anodes. Have a look at the schematic on page 11 in the Arduino based clock I have - it doesn't get much simpler than this. http://www.open-rate.com/Downloads/NixieClockV8InstructionManual.pdf Ian On Friday, 19 June 2015 22:55:55 UTC+2, wb9jfr42 wrote: Has anyone built a clock using MM5309 or 11 chip with nixie tubes Using BCD to a 74141 but don't seem to be able to multiplex i would like to use the chips that i have had for many years Thanks jerry -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
