Hi, I just bought an old Nixie clock design by "Karlsson" that uses a 1pps signal generator from what looks like a standard electronic clock with hands, I also found this "inner look" at another Karlsson clock that confirms what my clock contains more or less : http://www.nixie.dk/~jthomas/autopsy.html
What I wonder now is if anybody has hooked up a DS3231 with a small microprocessor to set it to output a 1pps signal on its output? The current 1pps generator has a big spread in time so it is sometimes one minute ahead and sometimes a minute behind but it also drags behind every day and I'd like to do the simplest update to the circuit and I couldn't find anything simpler with better precision than the DS3231 and then program it to output 1pps - if you have another idea on how to do this I'm all ears! Using a frequency divider on the 32KHz output would also be possible but I couldn't find any small chip that divided that right away. I don't have good GPS reception in my apartment, otherwise I would have used a small GPS-unit. /Martin -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
