[Autuin] wrote in to share a few things he’s put together using spare vacuum tubes he had sitting around. With no other practical use for the tubes in mind, he fiddled around and came up with a couple of items that could be neat to have around the house, depending on your style of decor.
The first item is a vacuum tube night light. While the tubes were not originally built with the express purpose of putting out light in mind, they do happen to throw out a nice warm glow when plugged into a suitable power supply. [Autuin] mounted one in a wall wart, driving it at double the rated voltage, which provides a decent amount of light.
His second creation is similar to the first, but meant for your tabletop rather than your wall. He stuffed a vacuum tube into a candle holder, added a power source, and called it a day. The vacuum tube candle actually looks pretty nice, and with a bit of tweaking could easily be made to behave like a candle as well.
The final item he shows off is a vacuum tube flash drive. Little more than a carefully hollowed out tube with flash drive guts inside, it is more suited as a permanent fixture than as a portable storage device. Even so, we think it looks pretty cool.
Have you done anything neat with old vacuum tubes? Let us know in the comments!
