It is a hand made one-of-a-kind nixie tube necklace! It’s a little large but where are you going to find such an unusual necklace? It is more of a novelty item but still can be worn to special geek events or wherever you like (not in the rain, please)! We have taken a genuine vintage Russian nixie tube and created a necklace with it! It is a Russian type IN-19V Symbol Nixie tube from the cold War era. It will display a plus (+) or a minus (-) symbol which is user selected via a switch. I suppose this could be used to select the user’s gender or whatever you choose. There is space to mount a cabochon or whatever you like on the front acrylic surface. The front is made of shiny black acrylic and the rear removable cover is black polystyrene plastic. The body is oak finished in clear lacquer. The size is 2.25 in. square by 1.25 in. deep minus the tube. The necklace is adjustable and adds a geeky touch.
It is battery operated and has a power switch to turn off the display when not in use. The battery should last for at least several hours if left on. Go to a party and dazzle your friends with this unique item! At night it really looks cool with its orange glowing neon symbols. Not only is this unique it has potential to eventually be a collectable item since these tubes have been out of production for many years and the prices seem to keep increasing.
High voltage is supplied by a high efficiency switching power supply powered by the included replaceable CR123 Lithium battery. The tube Is a Russian type IN-19V manufactured in the 1980 to 1990 time period that have a beautiful orange glow that most likely were originally destined to be used in Russian military equipment. Nixie tubes, unlike other vacuum tubes, do not have a filament. This has two major impacts on the operational characteristics of the device. Nixie tubes produce very little heat, and as such, do not require the kind of ventilation that other vacuum tubes need to function. Also, the tubes operational lifetime are greatly extended past that of regular vacuum tubes.
So why not be the first on the block to own something as unusual as this item? This is a perfect gift for the special geek on your list!
