Free Elektor Article: Nixie Bargraph Thermometer


Nixie tubes are always fascinating. Nowadays they are mostly used for clock displays, such as the project in the May/June 2016 issue of Elektor. The ‘Nixie’ bargraph tubes for analogue readout in the form of a column of light are less well known. Strictly speaking, they are not Nixie tubes because they do not display numerals, but they have the same warm retro allure because they are also filled with neon gas. The thermometer described here uses a Russian IN-9 tube and is a nice alternative to the usual clock projects.
