Nixie Clocks

George has recently developed an interest in Nixie tubes and has enjoyed building some into clocks. Jenny's first question was what is a Nixie tube? Well these devices were introduced in the early 1950's and are a form of numerical indicator using wire numerals that glow in neon gas - the whole thing being encased in a glass envelope, in a similar manner to a thermionic valve.

A voltage of 130 - 180V is applied to the required numeral, which glows a pleasing orange red colour.
