Now that the mains (in the UK at least) has no guaranteed long-term accuracy (UK does not subscribe to UCTE), it makes far more sense to use a 4060 & a 32,768Hz watch xtal - that gives you a 2Hz output that you can use a latch to divide by two to 1Hz - much more reliable... or to use a DS3231 for even greater accuracy... I spoke to mike about this clock some years back at a UK Teslathon - that's when he commented about not doing a design like this nowadays - he's a serious professional engineer (have you seen his massive polychromatic UFO flying over Rio de Janeiro & Gdansk? http://www.dezeen.com/2008/07/15/ufo-by-peter-coffin-and-cinimod-studio/) Nick -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
