What are 'Nixie' - tubes?  Nixie tubes are the LED indicators of the past. In the 1950's, 60's, and early 70's, there were no LED or liquid crystal displays.

So, neon gas filled tubes were used to display numerical data. These Nixie tubes were commonly found on scientific equipment, counters, voltmeters, control panels, etc. Nixies feature a characteristic warm orange glow. Having been widely replaced by newer display technology, Nixie tubes are no longer mass produced, which explains their price today.

Digital Nixie clock kit K8099 displays the time in either 12 hour or 24 hour formats on four Nixie tubes. The pictured kit enclosure is not included but is available separately.

This is an electronic kit rated skill level 4 (fairly advanced). User assembly of components and soldering is required.
