Today is a good day to be a LED, MAKE Flickr photo pool member Funnypolynomial writes – “I’ve had a thing for tubes (aka valves) since I was a kid. They made me thing of mini futuristic alien cities under a dome. I got some on ebay and mounted them on a plinth to make some mysterious object. Then I thought “Wouldn’t it be cool if they GLOWED?”… The LEDs shine up through the holes in the project box and make the tubes glow. “ – Link.
