Introduction: USB PEN DRIVE STORAGE CONTRAPTION
I have many old vacuum radio tubes laying around and I love the look of them glowing (as they would in an old radio) but not having an old radio I put one on top of a pen drive which has an unusually nice pulsing glow and there it was! Exactly what I wanted. The housing is made from an old electrical test box (gutted) and various bits of junk I had lying around (see description at end of video). Breaking open the pen drives is tedious but necessary to achieve maximum light output. I may build another one!
We have a be nice policy.
Please be positive and constructive.
