The other day at uni I saw a sight to make many here weep: a skip bin (or what others on this board would call a "dumpster") piled full of computers and electrical goods. The psychology department had decided to do a little cleaning. Here's what I scored:
A 500VA UPS in seemingly fine condition. (Someone from the department also vouched for it. Who examines the head examiners?)
Eight HDDs, four of okay size (~3GB)
More floppy disks than I'll ever need
A 55VA transformer
A coil of .25mm enamelled wire
Some computer power cords
Some lightbulb thing (more on that later)
What I could have scored (with a ute and tools):
Any computer since the Acorn Electron, and all associated parts
Tape decks
Monitors and TVs
Video cameras
A broken CRO
Stepper motors
Invertors
Etc
As I said, I was almost reduced to tears. Students were turning up and calling their mates. Some guy called it Geekmas. A small team of computing students were gutting all the computers - you know, PC PSUs, 44x CDROM drives, keyboards, everything. There was easily a few thousand dollars worth of stuff if the psychologists had bothered to sort it all. Insane.
The ID challenge? That's the lightbulb thing. I saw it and thought, hmm, that'll look cool with HV in it. Looking at it later, it's obviously a HV device of some sort. One of the leads is insulated and there is no direct contact between them. Otherwise it's the same size and shape as a normal lightbulb.

Happy Geekmas! It looks like a big neon lamp, so it would probably make a very nice plasma globe. It may well have a built-in ballast resistor so you can plug it into an ordinary 240v lamp socket. BTW, we also call dumpsters "skips" and university "uni" here (in the UK)

I remember watching on discovery about a guy in the U.K. who put lights and a motor in a "skip" and actually registered the thing. Back OT... Nice lightglobe!

Its definitely a neon bulb. Even shape is standard and not much unusual.
It is filled with low pressure neon and should glow orange when powered with several hundred volts, and as previously stated it may have resistor already built-in.
