would accept it on their wall — even with a power cord hanging from it. the clock can be built in either inch or inch diameter versions, depending on the nixie bar graph tubes used. while my first kit was a geekier design using technology for the clockworks to be more in line with those of the tubes,

. it sports a f capacitor for maintaining the time when there is no power. once fully charged, the capacitor will keep the time for a month or two with no power. because the clock only has hands (tubes), to determine the exact minute that the clock is on takes counting the blades on the 'propeller,'...
