Evil Mad Scientist Laboratories has a fantastic Nixie tube take-apart article and photo set —
Don’t you just love nixie tubes? They glow with a lovely neon color and have gorgeous stylized numbers– something you can’t get with a dot matrix– or even sixteen-segment LED or LCD display.
Recently, we disassembled a well-loved tube when there was a photogamer challenge to break something, and so we had a chance to peek inside and look at how they are made.
Warning: This article contains graphic images of the dissection of vintage electronics which may be disturbing to some viewers. (No working nixies were destroyed in the making of this article.)
