Of course I knew the orange-colered single-digit tubes from olden times. They were installed in different electrical measuring instruments like frequency counters and millivoltmeters. Many amateur radio transceivers were eqipped with these tubes and of course control cabinets for the automation in the industrial sector.
But over the time they was forgotten especially the "hype" about the new light-emitting diodes controlled the interest.
Once, at the end of the year 2016 while I was visited a nice colleague for a hifi-sound-check I saw SHE! A clock, equipped with these tubes. It was love at first sight. I became aware that her name is "nixie". How romantic! Since that day "nixie" stick in my head.
At the beginning of the year 2017 I had 4 nixie-devices and they will not be the last.
I do not know of an other electrical component which is able to illustrate particle physics and electrical technology in such a simple manner. Furthermore the nixie-tubes are a real three-dimensional display. The watching of the "numbers change" is so beautiful as the first snowfall in winter.
