Nixie tubes make for fun projects but the fun can’t start until you get your hands on the hardware. Well, [Dieter’s] got you covered with his one-stop repository on Nixie tubes and where to get them. We know that Woz’s watch isn’t currently available because of a lack of tiny tubes an obsolete accelerometer. Ladyada’s Ice Tube Clock depends on a rare 8-digit VFD tube. But you can get around parts obsolescence by adapting these designs for an available replacement. So when you take on the Dekatron Timer or a Bottled Nixie Clock you’ll know where to turn for the goods.
Update: Our mistake about Woz’s watch. It wasn’t a tube shortage that put it out of production.
