Where Can You Buy Jumpers?
tekrat asks: "Here is a
wacky question, and one I'm sure has frustrated millions of us
hardware geeks. While we're moving towards jumperless motherboards, a
good deal of them still require that we fiddle with jumpers to change
things or when we upgrade. Or perhaps we're adding an internal SCSI
drive and need to set it to a particular ID. Nevertheless, through
the years, those little jumpers have come in a variety of sizes, all
of them microscopic enough to easily get lost on the living room
carpet. Without scavenging existing hardware, where does one go to
obtain jumpers? I haven't been able to find anyone who sells them, and
that makes me curious as to who even makes them for the motherboard
or drive manufacturers. If anybody knows who sells a package of
various-sized jumpers in a pack of 100 or 1000, please point 'em out
and you will have my eternal gratitude."
I always just rumaged through severely decrepid and archaic computer parts and ripped the jumpers off of them. Go through your old hardware and rip the jumpers off the parts you know you'll never need.
If you live in a world like mine, your locally owned computer store will have a whole box of jumpers, motherboard offsets, Y-adapters for power and the like. I was a good customer, so they would just let me rummage for the little bits I needed.
Right at the top of the page. It took me 15 seconds on google to find it.
If tits were wings it'd be flying around.
...of course it became way obsolete over time, and I scrapped it, except for the still-useful jumpers.
You could've hired me.
I have always just ripped apart old hardware in my deep, dark closet of oboslete and obscure hardware, but, if for some reason you need to short a circuit and the poles for the jumper are just too close or too far away or too thick or thin or whatever for your recyled jumpers, you can always wire-wrap the poles together. You can get a nifty little tool at RadioShack to do this with and it will make you feel good and geeky. If you don't have at least one closet filled with a half dozen 386's and parts from a PDP11's tape drive or something like it, you have not yet mastered the ways of the force, young Skywalker.
It is a very interesting question, though. I bet they're made by the same fine folks who labor over those little plastic houses for monopoly games. I hear they're financed by Fannie Mae Micro.
I've got many (working) 8088 through 80486 class machines out of it, as well. The ones that didn't work, or simply had no use to me, I tear down for components, including jumpers. From doing this, I've got two drawers full of useful expansion cards, a rack of hard drives, an armload of 32-bit x86 processors, and more jumpers than I care to count. :)
Not to mention spare keyboards, internal cabling, power supplies, monitors, printers, and modular cases. All of which come in just as handy for me as those little jumpers.
Just go to the local Mom and pop computer part/repair store. They probably have 10,000 sitting in a bowl in the back

I know for a fact that the Portland (Willsonville) Oregon Fry's has a variety of sizes of jumper. They are a good resource, if you happen to have one in your area.

SeaGate SCSI drives perhaps? They use these REALLY TINY jumpers that you practically have to use tweezers to handle. However, check your old pile of Quantum and Maxtor hard drives. Quantum Lightning and the older Maxtors (my 800MB one used them) used the two types of tiny jumpers like are used on some SeaGate SCSI drives.
:)
Your local mom&pop shop probably has thousands of them. I stopped by one that was oging out of business and they gave me a small box (about the size of the ice bucket in your average freezer, which is what I'm now using) full of various sized computer screws. They probably had the same thing only with jumpers

Go to www.cyberguys.com they have jumpers and every little computer screw you could imagine
I have ordered from them many times and have always gotten goo service
I haven't seen jumpers for sale in a lot of places, so I just collect them from old motherboards and whatnot before I toss them in the garbage. It's easy to build a collection that way.
I have a feeling that jumpers won't be around for much longer anyways, since everything is moving towards being software-configurable (PnP and whatnot)

here is 100 for 4.99

I want to find a place that sells sexy electronic components, neon-colored jumpers, clear-plastic power cables. Think Ikea, think iMac... I want it for some costumes and to decorate my Bicycle for critical mass (I have blinky lights, I have EL wire, I just need some damn sexy wires!)
Where oh where?

Assuming you want .1" jumpers:
In the lower right hand corner of P65. or in the lower left of P66
other sizes are available too.
Mouser probally has them too.
Web site leaves nothing to be desired, including visual searches for the thingamajig you have no idea what to type in a search field for.
Before I part with'em: two pennies weigh ~4.996+/-0.014g, have a zinc core, and the face of Lincoln. You can keep 'em.
You can cut & bend a staple to the appropriate size, if it's a real emergency. I wouldn't recommend this even for a short-term solution, though, unless you're really desperate.

Most of us have equipment we can loot for jumpers (old 2x CD-ROMs, 20MB Hard Drives etc), but your best bet is really a local ma-and-pop shop and just offer $5 or so for some mismatched jumpers they've got in the back. You'll get more than you're likely to need (even if you're paying 2x retail), and you might just make a friend

/.'s motto should be abandoned as crap. News for Nerds, etc? Uh, no. I'm a traditionalist, so my vote for the new slogan is "Slashdot: Natalie Portman, Naked and Petrified!" Or something.
gotta go, grits in my pants are getting cold.
Computer show and Sale, travels around, comes into each area about once a month. I got little packs of them there for about a dollar for 10. Depends on the vendor I'd guess. http://www.marketpro.com/

A Few Hundred = never having to buy jumpers again
... as time goes by we will need increasingly fewer jumpers (demand side) Whilst conversely as you retire those old servers the supply side will increase in the short to medium term.
.... a draw full of jumpers .... heck some people sweet LEDs of so why no jumpers.
.... this a supply and demand situation as mentioned in the original post
So if he takes out a small loan of say 100 jumpers then he can pay the loan back at a rate of say 20 jumpers per year with an interest rate on the loan of 10% per annum.
...been there done that
All the people saying "use a search engine" in more or less civil tones, shut it !
I'm interested in the questions that get asked here. I wouldn't have thought to ask this one, and it's nice to see the answers - if you think the answer is self evident, move along.
Google et al will tell you a lot, but they won't tell you if the supplier is any good - that's the sort of insight that Slashdot is good at giving.
This sort of "Use a search engine, don't ask here" is the sort of unfriendly BS that will drive new people away from any site. We all have the occasional stupid question.

15 seconds? What's the matter with you? Don't you know how to type? Or are you stuck with a 14.4 modem, you poor bastard?
Ask Slashdot has reached an all time low!
I like the narrow-interest questions too. But that's not the same thing as "I'm totally clueless, tell me what to do," questions. These belong on bbs-style sites or USENET.
Nothing is more stable. Well, except for some other things.
I bought over a hundred off of EBay just the other month!
Seriously, doesn't anybody even do the most basic of searches anymore?
