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.

What is it?

Does it have the usual connectors? ie bayonet/screw fitting?
I take it by the phrase "ute" that you are in fact australian.

Awww, I don't know if tasmania really counts... tsk tsk... ;)

It's not a blacklight or anything is it?

Yes, I am Australian. On this topic, how widespread is the abbreviation, "uni", for university? (Here "college" means secondary high school.)

Edit:
Blackplasma: I haven't tested it at all yet; UV source did occur to me. I should find the time to stick some HV onto it this Easter break.

Looks like a standard gas discharge lightbulb, propably neon or argon. I think they were used for nightlights and stuff like that.

Link2 Look around here under discharge lamps.

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)

If it is vacuumated (no inert gas inside) could be some physics tool to demonstrate the thermoelectric emission.

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.

Yep, it's a neon. I worked that out as soon as I got out of my theoreticist armchair and plugged it in.

It's funny; I've actually got loads of little neons that look just like it. I was completely thrown by the lightbulb shape.

Wow! So pretty... (The happy-snap digital camera doesn't do it full justice.)
