Scrounging for Fun and Profit

When Bruno Bauer inherited Zebra, a retired 2-trillion-watt pulsed-power machine...
Man, I wish my rich uncle would die and leave me a 2-trillion-watt pulsed-power machine!
He purchased it for just a few hundred dollars from the lab which had been clearing out their parts warehouse. It took him a few months to get it working again, but a few weeks ago I was present when he performed his first successful "atom smashing" in his upstate New York backyard.
A glorious experience, to say the least.
Got Rhinos?
Think about it for a second. A whole new season of junkyard wars... With nukes...

Atomic batteries to power! Turbines to speed!
research scientists scrounge around for stuff?
It makes perfect sense, i know a few researchers who go out every weekend to scrounge for some Dewars.
Little tip to junk lovers everywhere: Every physics department has a room or two that they don't use for anything. What happens is that equipment that no one needs gets stashed there and forgotten. I've dug up everything from high precision mirrors to fiber optic by the yard, and bits of machined metal I couldn't identify but thought looked cool. It helps if your department hasn't redecorated and refurbished its digs in a long, long time.
Scrounging and scavenging equipment is a vital skill for all experimental scientists. It's usually more along the lines of finding the unused goodies that somebody has stashed in the back of their lab than finding the expensive stuff described in the article, but everyone without military-class bugets learns to do it. (Actually, I'll bet that even the best funded darlings do a lot of scrounging, too) Figuring out how to use the components is sometimes a bit of a trick, but there are few things as fun as finding a pile of junk and figuring out how how those components are going to help your next project.
There's no point in questioning authority if you aren't going to listen to the answers.
Anyone else see potential for Laboratory Wars?
there are no stupid questions, but there are a lot of inquisitive idiots
"If you get a 100-kV power supply built in 1950, chances are you'll be happy. There is continual improvement, but no quantum leaps. Computers are the most useless--they are right up there with disposable diapers in landfill."
Oh, how true that is. And it applies on a personal level. I have a basement full of computer crap to prove it. I thought "Oh, I'll put them together and make some usable systems for a local charity." BZZZTT! The local charities won't even take anything less than a P5 or pm601 system. They say 486's and 040's cost more to test than they can sell them for. Frankly, it's hard to find a place to dispose of them.
But peripherals, cable and infrastructure stuff? That's a different matter. I picked up three fiber transceivers from Value Village a month ago for $5ea. Ditto ($7) for a HP Deskjet 1600 (the big 9ppm postcript color inkjet w/jetdirect). IMHO, local thrift stores are great for this sort of stuff IF you don't get sucked into buying more stuff to fix the great deal you got.
Looking for little stuff like power adapters, modems, printers, etc? Head for the local thrift store. Looking for wiring or shielding? Check out industrial supply places (like Pacific Iron & Metal in Seattle, where you can get castoff spools from the local telcos). Looking for bigger infrastructure bits? You can get rackmount cases, cable, sensors, and all manner of interesting bits directly from telco salvage units, places like re-pc, or if you're nearby, places like Boeing Surplus
A little time spent doing some smart looking can save a lot of cash. Otoh, A lot of time looking can be a huge waste. You just gotta know when to stop and pay retail.

That if you don't scrounge, then, well... you are just a wannabe geek.
Here in Phoenix, AZ - I scrounge on everything (hell, just yesterday I managed to obtain a couple of old PCs from my work - nothing of great interest in them, but the cases are nice - they were headed for the trash, from what I understand). I have several sources - both in the "pay-as-little-as-you-can" to "free-for-the-taking":
1. My work (free old junk)
2. Apache Reclamation and Electronics (cheap small and LARGE junk)
3. Electronic Materials and Computers (E^3) also known as Elitech (sometimes get ripped off here)
4. Dave's Computers (still checking this place out - owned by a guy who got shafted at E^3)
5. Some place on 9th Ave and Madison (Westech or something - want to check this place out soon)
6. Global Recycling (still need to check this place out - they are only B2B, so need EIN or something)
7. Equipment Exchange (behind BOB on Grant or Lincoln - great place for strange and big manufacturing stuff)
8. There is also a metals company off of (Washington?) across from Greyhound Park that is cool
For everything else - late night Friday/Saturday runs through dumpsters! Behind Nortel, Honeywell, many business/industrial office parks - great fun. Just bring a flashlight, some gloves, and throw a few boxes in the truck (to tell security guards you are moving and looking for boxes - most of the time they will leave you alone, or at worst, ask you politely to leave - don't hassle 'em, don't stick around - just apologize, thank them, and LEAVE).
I remember one time near Metro Center finding a stash of old computer equipment, another time behind a Honeywell finding some old minicomputers and terminals, and a big winchester drive (all the stuff was too big to even THINK about lifting). One time over at a Nortel my friends and I found some kind of telephone equipment rack - we grabbed that real quick. Another time we found a bunch of Narcotics Monthly magazines (funny thing, this was in a business park - not sure WHY these were there, unless some PI had an office there).
For the rest, there is always online retailers of used/surplus junk (I have a ton of links, too many to list here). Of course, the final place to check is Ebay.
Great fun buying and finding used stuff...

--and nobody's yet proposed taking charge of it for the sole purpose of world domination? What's wrong with these geeks??
The things I would do with a petawatt laser combined with, say, a small collection of orbiting satellites simply boggle the mind....
When I was in high school me and a buddy of mine helped the chemistry department head "inventory" the stock during a big move. We got everything under the sun. Unfortunately, we found out that some of the containers were mislabelled, and nearly blew our heads off opening a can of ether.
Just a warning that scrounging isn't risk-free.
