Building A Giant Vacuum Tube Smart Lamp

Vacuum tubes are pretty, which is why they’re often showcased externally on

Vacuum tubes are pretty, which is why they’re often showcased externally on exquisitely-expensive home Hi-Fi hardware. But if you just want to gaze at their beauty without making any noise, why not build this vacuum tube lamp from [Noel Törjék] instead?

[Noel] got into some creative reuse with this build, with the main body consisting of a bell jar and wooden bowls. The internal structure is then created from jar lids, wire, metal sheeting, steel rods, and galvanized wire mesh. Simple modelling techniques are used to assemble the internal parts of the "valve," including the grid and the electrodes and so on. As for light, [Noel] employed a ZigBee LED driver that he could control over his smart home setup via a Philips Hue bridge.

The final result looks like an extra-large tube. Anyone who knows what it is will spot that it's not a real one, but they’re also exactly the audience that will appreciate it for what it is. Everyone else will probably just think you’ve taken an interest in strange art-deco replica lighthouses. It's not the first time we’ve seen replica valves around these parts, though, and we’re sure it won't be the last!
