Hi, I am thinking of building a nixie tube counter that counts from 0-60 counting up every minute. I am going to use 2 4017's to do the counting but I am stuck on what to use for a suitable pulse generator that would create a pulse every minute to make the counter count up. Would a 555 timer work for this? or am I going about it the wrong way? It doesn't have to be accurate it is just for display. Any hints or help would be appreciated.
Thanks, Tom Waymouth
Since a 555 would be extremely inaccurate, how about wiring an optical or hall-effect switch to the second hand of a real clock?
Google for the many nixie tube clock designs on the web.
Have a look at

void _-void-_ in the obvious place
Look at the 4060 oscillator/divider chip.
Thanks everybody the links and hints have been very helpfull
Since you'll have 6.3VAC, rectify it and turn it into a 50/60Hz pulse stream then divide to suit.
Cheers.
