I don't remember that one in particular, but it sounds like something you'd find in "Elementary Electronics" magazine. I subscribed to this magazine for years and quite enjoyed the construction and theory articles, but didn't bother with the extensive CB radio coverage. http://americanradiohistory.com/Elementary_Electronics_Master_Page.htm <http://americanradiohistory.com/Elementary_Electronics_Master_Page.htm> I scanned the six issues from 1972 but didn't see any minitron (or numitron) clocks. I'd guess projects like that would be a few years later, when clock chips became commonly available to hobbyists. - John -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
