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,

on the larger tube; and pin is an auxiliary cathode. the tube is driven by always having v on the anode, then pulling the cathode to ground through a resistance. a transistor is used to vary the resistance and hence the amount of current that flows through the tube. the higher the current, the longer...
