Making Stuff Out Of Broken Computer Equipment?
Class Act Dynamo writes "Recently, my keyboard stopped working, so I bought a new one (nice cordless number, really excellent). I was about to throw the old keyboard out when I thought it would be interesting to take all the keys out of it and turn them into refrigerator magnets in order to have a simple 'megnetic poetry' type of thing going. As the fumes from the industrial strength glue went to my head during this project, I began to wonder what other types of craft-type projects people had undertaken with their unusable old perpherals and such. Then I began to wonder why there was a purple octopus on my couch. I decided to ask slashdot readers the first of these questions."
What about the good ol' Celeron Paperweight?
Because purple octopi like to watch TV too.
And yet half of the answers will be to the second!

I've got an old pentium 2 or so that I use to hold papers and notes on my desk. Then there's always the fun RAM keychains and motherboard clipboards I've seen around.
I've discovered a remarkable proof, but this margin is too small to contain it...
out of old HDDs http://afrotechmods.com/cheap/hdspeakers/hdspeaker s.htm
My cousin has made many, many things. She has turned old hard drives into clocks, PCB from old AT motherboards into a giant table, and AT motherboards (this time with all of the components left ON the board) into clocks as well. She has made various other things that I can't think of at the moment.
Her website, including links to some kickass PC mods that she had done, can be found here.
Listen to my experimental-industrial-techno!
I make computers out of them.
Computer cases with clear sides make great hamster cages! Just make sure to file down the really sharp stuff. Add some tubes from case to case and papow! You've got your first Hamster-powered cluster.

a classic use for old computer bits is making them into jewelry- things like capacitor earrings, pendants made out of those little copper-wrapped magnets, pins made from colorful heat sinks and interestingly-patterned chips.
They make good refirgerator magnets, as well. And if you're patient, you can make your own motherboard clipboard.

The original, classic broken computer mod is probably still the best place to keep your purple octopus. Various references are available.
Breakfast served all day!
I distinctly remember seeing someone selling "RAM Buddies" at a local art fair around here awhile ago. They basically took that really old ram chips (the one that used rectangular sockets), bent the pins outward, and stuck eyes on the front and a tail in the back so they kinda resembled little caterpillars.
is the one they put the printer to in Office Space.

I suggest finding a microwave you don't particularly value and put your motherboard in it. If that doesn't entertain you enough, a light bulb can have an entertaining reaction.

A friend of mine a while ago would make neck chains out of old HyperSPARC and SuperSPARC processor modules, ala Flavah Flav from Public Enemy.
yeah, HDDs are the most useful eq.
they can be used as ashtray, weapon... and working one can be used to store some data on it too.

The answer is three weeks.
Three weeks until your girlfriend gets sick of asking you to clean up the overflowing pile of old and unused components that's steadily taking over the office. Three weeks until you come home and find your monitor decorated, in a most Martha Stewart-like fashion, with superglued sticks of RAM and old CPU's.
Message recieved.. loud and clear. Over and out.
Back when I worked in the computer room at K-W Surplus (please excuse the horrid website, it isn't mine) we took this box of old 486DX chips and glued them onto the ends of these long thin plastic pencils. They made excellent back scratchers. We sold them for $0.99CA I think.
I stuck them to either side of the flap of skin between my nostrils. Going to the doctor to get neodynium magnets removed from your sinuses isn't fun.
I use my ex-speaker magnets for finding lost metal items.
My ex-cabinet houses 3 birds.
I use my earlier corrupted HD for slicing soft items after making some big changes in its circuitry.
I have mounted my CDROM's tray on wall, cut out a piece of plastic artistically and now it holds abt 10 pens, a cup of water, and upto 5 CDs, all separately in diff slots.
First of; I make my living buying discarded computer stuff and reselling it. A lot of this stuff is broken and gets trashed. When I do have time I tend to strip the stepper motors out of disk drives and printers as well as the printer guides for CNC / robotics stuff. UPS batteries are an excellent power supply.
However mostly I use discarded equipment to put a working system together again which can be used for all kinds of things: If you are handy with linux you can make excellent routers; web servers, media servers, a TIVO, CNC control equipment out of the oldest stuff.

haha! I did the exact same thing, though it wasn't a mac, it was an old 386. The ram was only 256kb in size! I remember we tried to install linux on it back in 99 or so, but even though it had a dozen or so sticks in it, it didn't meet the 3mb of ram minimum - so on the keychain it went!

I've been working on a project for a few months now, utilizing parts from old drives. I'm time deficient of late, but I'm hoping when I finish a current work project, I'll have more time.
All you tinkerer nerds out there, if you haven't looked into BEAM robotics, look into it. You can utilize a good deal of junk electronics.

When will I end this grieving ? When will my future begin ?
I once had similar ideas for reusing the bits out of all the old PC's that collect around me (mostly P233's and desktop cases, for some reason, but I've got a PS/2 hiding somewhere).
:-)
Was going to use the old fans to make sure airflow went through my PC and even throughout the wooden cabinet that my PC is in so that it wouldn't get too hot.
Or:
Actually once crafted a primitive noise baffle for the exhaust fan from a PC by using an empty 5.25" casing and some defunct floppies arranged so that the air would zig-zag through the 5.25 case (off of a CDROM if I remember rightly, with the bits taken out).
Or:
The metal casing of an old PC is good for keeping all those ADSL routers, printer server boxes, ethernet hubs etc. that are on 24/7 but just get in the way when you're rereouting cables.
Bung them inside an old desktop case (even mount them in the drivebays or whatnot), run all the cables through the PCI backplates and power them off the inside of the power socket (even room for a power strip with a few "brick" power adaptors in there). If your stuff needs 12 or 5v, you could even run it direct off of the old PSU, I suppose.
That way, one box and plug powers all the silly peripherals but you haven't got millions of wires tangling and twenty brick adaptors stuck to the wall.
You can move the bits inside around so that you can see the LED status of things from the drive bays etc., can power from the power supply, can even re-use the PSU or case fans to make sure they have adequate cooling etc.
Or:
Some people try to hide their computers in their furniture (e.g. wooden cabinets/cupboards/desks), why not go the other way... convert the front of a desktop case to become a fold-open drawer or storage area.
Or:
See how many LED's you can fit onto the outside of an old PC case so that you can have that authentic "Star Trek" feel. Bonus points for them actually working, extra for flashing effects etc.
Or:
Build a race track using old PCI cards as barriers, upside-down motherboards as the floor and the balls from mice as the "cars", like blow football, only more geeky.
A hot air paint stripper will surface mount components even more easily but it's hard to use surface mount components.
I think many people neglect to realize that the computer components were designed to operate in a closed box and to have very little direct contact with people. There is plenty of lead and other nasties in these components that I certainly wouldn't want to handle them frequently or for that matter my kids. Now things like keyboard key are obviously safe, but motherboards are another thing.
Since you're only using the keys from a single keyboard for your fridge magnets, a question arises: what's the longest english word that only uses each letter once? How about the longest sentence?
I'm sure I've seen "toys for girls" that look just like my MS wheel mouse. I'm sure it can't be that hard to plug in a vibrating motor and some batteries. If you make it a wireless one you could even use a caddy to charge it. And the best thing is that you don't have to worry about someone finding it in your desk draw. You just say it's an old broken mouse. Kill two bird with one stone. Hell you could do it and have it stay as a fully functioning mouse too.
A local (for me, local = Des Moines) band (long disbanded, alas; they were quite good) used broken terminals as a backdrop for a performance. They weren't hooked up to anything (save the outlet, of course), but they were sufficiently fried that the CRT traced a pattern on the screen with no input at all.
a classic hack (i don't know who first thought of this) is to take a handful of 128k macs and line them up and run software to display the time of day, one digit per screen. you can get arbitratily complex, with or without seconds, with a screens for the colons (flashing or not), date, networked or not, dali morphing, etc.
I once made a necklace our of a dead mac mouse... just fed the end that normally attached to the computer back into the mouse case, and voila!
On a dare, I wore it out one night (while still in college). I took it off when a hot girl asked me why I was wearing a medic-alert necklace.
Other then the tried and true practice of using toasted CDs as coasters, a friend of mine found old processors (of the socket 370 variety) made an excellent comb for his goatee.
At a computer place where I volunteer, they hand out old RAM chips cut in half as key chains. They slide the ring though the holes where the memory would click into place and slap a sticker with their name and phone number on the back. A big bowl of them sits on the front counter and the majority of people who come through take one.

In school i was always the geek, the odd one out etc...
Just check http://djsmiley.blogdns.com to see.
Sometimes i would play on this fact and i 1st made a keyring out of some old ram i found in the computer room. (now i find its been done before =[ )
Then, i found a LARGE ISA card and stuck that on a keyring, to take the piss. The 1st years were loving it, til i hit one of them over the head with it and split it in half =/
Over time this story of this keyring got around, with people asking to see it... Eventually i got bored and dumped it.
Then i saw hackers (the film people, the film!) and decided i wanted a new keyboard, for some cheap pc i brought of a friends uncle, i had 2 cans of spray paint... I just forgot to mask the letters off. So then i ended up with a keyboard, only i could use... It became the most "bling" necklace ever, as i walked into 6th form waring it around my neck!. (using the cable as a string).
This was the high light, but i also decided after we tried to fix the school computers (taking them apart and putting the working parts in the same one), and finding it still didn't work, that if i took lots of NON-working parts, and placed them in a broken machine, it might just work...
how ever it just got attacked by the mobs and left on a bus somewhere.
So, paint your keyboards and go hang out on the west side...

I found out that printers, especially those made by Lexmark, make very functional doorstops.
I purchased a lexmark printer last year and it turned out that they didn't make win XP drivers for it. I called tech support and they told me that I could use my printer if I reverted back to win ME or earlier.
Having no use for the printer, I affixed an appropriate sign to it expressing my discontent with lexmark and used it as a doorstop. It worked well for propping the door open a few inches, the flex of the plastic helped to bounce the door back so it wouldn't hit so forcefully, and best of all, whenever I was pissed off, I could just kick the printer against the wall.
Break the mindless monotony!
You can wire up a joystick and a few buttons to be used to interface an old keyboard into a MAME Machine's arcade control panel.
Harddrive magnets are great. In fact, they are rather expensive, and quite strong!
Even better, if you have a broken CD/DVD-player, you can extract the electric motor. It's a high-quality product. A lot of people convert them into small, high-performing engines on R/C aircraft. This is one example

Making stuff out of broken computer equipment in nothing. Back in my day, we were making computer equipment out of broken stuff. And we were grateful! Seriously. Have you ever made hundreds of NAND gates out of broken TVs and radios from the junk yard and used them to build a huge binary calculator? With multiplication? You might laugh, but in my opinion that was something to be proud of.

I built a 4 color marble sorter out of two stepper motors from 5-1/4 inch drives, a photo-sensitive cell and some PC software driving parallel port inputs and outputs. It won $150 in a engineering contest at Auburn University.
Commonsound Collective (see 4MS section) has a line of DIY stompbox effects you can build in the privacy of your mad scientist laboratory.
4MS specifies electrical junction boxes as chassis since they are cheap and durable. I've always found them a bit too tall so I use dead hard drives for the chassis instead.
They do require a bit of grinding but the RF shielding seems to be far superior to junction boxes.
I recently pulled an old SCSI drive out of one of 3 dead DG Aviions I have (which make fantastic speaker stands, by the way) and have it all cleaned out to make a Noise Swash.

Recently I took apart several old 2.4 gig full height hard drives and recovered the magnets. These guys are extremely powerful and will cause injury to fingers if careless handling two of them at the same time.
Anyways I found them to be very good stud finders as they will quickly locate the screws or nails hidden in drywall and are powerful enough to hold themselves in place.
I have taken two of them and fashioned a small clip on top and pulled a chalk line between them. This arrangment is great for creating a nail line.
Also a placed one in a small pocket in my electrical tool holster. Then fasteners and small parts stay attached to the outside making them very accessible. In fact, when working on something I just throw the small parts in the general direction of the pocket with the magnet and they stick.

One time my cousin Walter got this mac stuck in his ass. True story. He bought it at our local mall, so the whole fiasco wound up on the news. It was embarrassing for my relatives and all, but the next week, he did it again. Different mac, same results, complete with another trip to the emergency room. So, I run into him a week later in the mall and he's buying another mac. And I says to him, "Jesus, Walt! You know you're just gonna get this mac stuck in your ass too. Why don't you knock it off ?" And he said to me, "Brodie, how the hell else am I supposed to get the one button mouse out ?" My cousin was a weird guy.
Out of curiousity, what nation's currency do you use, such that this would work? I believe the Dutch and Canadians use at least some magnetic coins. The coins that currently clank in my pocket are American, however, and are all non-magnetic.

You've got a point there. Many don't realize that once magnets get to be a certain strength they get dangerous--even something comfortable enough to otherwise carry around for curiousity value. Imagine this embarrasing scenario: You carry around a neodymium magnet around in your jeans pocket and wander into the subway and brush up against the steel turnstile and CLANK! There you are!

That was the turning point of my life--I went from negative zero to positive zero.
I've had ideas for things to do with dead hardware, but I dont have enough of it layin around. Where do you guys go to find good stuff when you have a project in mind? Right now I'm think I need some dead hard drives, which I could probably find if I jumped into a computer shop's dumpster. But it'd be nice to get my hands on something larger than a 3.5".
Install pegboard to entirely cover one wall of your computer room or office.

Amiga joystick? On parport interface. Etc, etc...
I actually took an optical encoder from an inkjet printer and used it in my thesis work.

Good luck!)

Platters from dead hard drives make really cool sounding wind chimes. They also develop an interesting patina after a little bit of outdoor weathering.
cut the cables off, put them both behind the rear tires of a front-wheel-drive car. roll car back onto keyboards, engage emergency brake tightly so rear wheels stay locked over the keyboards. put car into gear, slide around and do donuts on your new plastic "car skates".
Wasn't really me, but I laughed my ass off reading the story. :)
I have a friend who used some hard drive magnets in the gas tank of his '65 Mini so it would collect all the bits of rust and metal to it instead of feed them through the pump and clog up his fuel filter. Mind, it would have been better to replace the tank...but hey, it's cool.
I work on different art projects, and one of my current projects involves using parts savaged from chucked out PC's, printers, montiors, and the like.
My carrying structural element is a plastic milk bottle, common down under.
Out of all this and with the help of a black marker, I create little Milkbottle People (old CD's are great for ears).
I wanted to make people smile, when they see them. Thinking especially of kids. Then at night I go around, and hang them up in different places. Trying to integrate the Milkbottle Person, with its environment (e.g. make them look at something specific).
In another project, I use broken bits of circuit board to draw portraits. This is more difficult, and to be honest, I haven't managed to create a satisfying object yet.
I have also used the discs of hard drives, to create a mirror for a geeky friend of mine, who needed a little mirror for shaving.
Last but not least, I use the empty cases to build my shelves, desks, and other non-secific-use objects (coffee table, morph, laptop table, morph, lamp stand,...). Besides the fact that I don't have much money to my disposal, I can't be bothered with worrying about my furniture every time I move. Which I seem to be doing a fair bit.
I like to make containers to hold my chips out of my old wireless antennas. I also like to cook my noodles with some of the other old computer parts.

Actually, the English system for pluralization is quite simple compared to many languages. We do in fact have a fairly regular pluralization scheme. There are several exceptions to the simple -s/-es pluralization, but take a look at some other languages. Latin has 5 different declensions, each with their own pluralization. Even with this many classes, there are still exceptions. German pluralization is very complex. Nouns may pluralize with -n, -en, -e, -er, or by remaining the same (there may be even more, my German is a bit rusty) based on the ending, and sometimes involves a vowel shift somewhere else in the word. Old English, like these other languages, had several noun classes with several pluralization schemata. It is only due to the Normal conquest in the 11th century that Middle English and Modern English are as simple as they are in this regard. English during the Norman occupation was a language of the common people, with Norman French being the language of court. This led to a lot of simplification in the language. The words that have irregular pluralization are generally the result of one of two scenarios. If the word is Germanic in origin (as are all of the examples you gave, as well as many more: child, sheep, deer, fish, ox, etc.) then generally is has kept a version of it original plural because it was so frequently used. Each successive generation could hear the "proper" plural frequently and emulate it, while being corrected by their parents if they improperly pluralized it. This would not happen as frequently if a word was not used as often. We can see this even now. We are much more likely to know that the proper plural of child is children than we are to know that the proper plural of matrix is matrices. The other branch of irregulars are words that were imported from another language, such as octopus (Greek in this case). I don't think that the person (or persons) who corrected the pluralization of octopus were doing so to make fun of the individual who pluralized it as octopi. I know when I found out that the plural was octopodes, I was highly entertained, and told lots of people about it, because it is one of those instances where many of us (myself included, in this case) try to sound educated by using the "proper" plural instead of saying octopuses (which is a totally acceptable plural, by the way), and it turns out that octopuses would have been closer to correct. We just overgeneralized a rule that applied to Latin loan words and used it with something that is not from Latin. Also, I disagree with your suggestion to strike all irregular plurals from the English language. Language is a free-flowing thing. For years, countless people have tried to change language to suit them and what they see as logical, it just doesn't work. If you were to succeed in your vision there, we would not really be speaking English, but rather a created language based on it. But don't worry, we seem to be moving closer to regular pluralization. A lot of the acedemic imports from Greek and Latin are at least beginning to get -s and -es endings. Children and feet are probably going to be around for quite a while, but time will probably regularize many of the less-frequently-used irregulars. OK, now that I am done with that frightfully long and very off-topic soliloquy, let's get back to using computer parts in innovative ways.
Dear AC,
Thanks for the tip.

The real danger with strong neodymium magnets is that they are both brittle and extremely magnetic--as a result if you accidently let two of them stick together, they can sometimes attract with such force that they shatter and send thousands of poisonous shards out at high speed. Hence the reason why you should always wear hand and eye protection when handling them. You should also avoid handling them if their protective coatings are broken as the rare-earth metals are extremely toxic and easily absorbed via mucus membranes.
Impossible, just another way of saying really hard--given sufficient time, all problems are solvable.
Personally, I've made an aquarium from an old monitor, and countless clocks from 3" and 5" HDD's. I've also made a few photo frames from old laptops. Usually I end up giving them to friends and family since they're sort of first to request. I've also made the (already mentioned) keychains from ram chips, but I can't think of what to use all the HDD magnets for. I also have a ton of HDD, misc PCI, and MB PCB's that I can't decide what to do with. I've seen cufflinks on Thinkgeek, and clipboards a few years back, but I hate ripping off all the components from the boards...

My gf likes to pull apart old computers. She wears ram in her hair (on a head band), and has installed a cpu fan in a pair of pants (rigged up to work with a battery). Those pants also have a number of resistors stitched down the seam as a binary representation of the asci characters: 'V', '=', 'I', and 'R'. She is currently working on using old motherboards (and other components) to create body armour.
You can make quite interesting ancient-Egyptian-looking (sort of) necklaces out of various resistors. Packages of new ones, to be had cheaply at the Shack, are better for this purpose than recycled ones.
We have a Mac-Quarium here in the house, created by my son. All I can say is that it's a mixed blessing. If you decide to build one, cultivate the friendship of the person who cuts your glass for you--you'll be seeing a lot of him. It has leaks despite the best prescribed adhesives. It also won't accommodate the heater, filter, and aerator needed for any sort of interesting tropical fish, so you're pretty much limited to a goldfish or two.
I believe ours has become a Mac-Terrarium for that reason.

In Soviet Russia the insensitive clod is YOU!
Ferrous metals aren't neccessary to the demonstration of inductive braking. The relative motion of the coin to the magnets induces eddy currents in accordance with Lenz's Law. The eddy currents generate their own magnetic field opposed to that from the magnets, causing the inductive braking effect.
With strong magnets like those found in harddrives, the effect is quite pronounced with a simple coin.
Please refer to this article for more information and links.
Doesn't matter. Magnetic braking is caused when conductive material is moved through a magnetic field. The induced current causes a resistive force in the moving metal, slowing it down. This works very well even in completely nonferromagnetic material such as aluminum.
Magnetic braking is in fact used in vending machines to slow coins by just a certain amount, to test against slugs. Wrong alloys will be slowed too much or not enough; either way, they can be rejected.
See question and answer #14 here for more details.

Handicam's in the US use NTSC. Most laptops use a propritory digital parallel interface. Most are VGA and above. They DON'T use the slow television sweep speeds. Unless they used a scan converter, broke out RGB analog and converted it to RGB digital, I doubt anything as simple as connecting the output of a camera to the input of the LCD display happened. Using a portable DVD player with a video input would be more believable. Getting consumer NTSC video into a laptop display has never been an easy patch.
Better night vision can be had with an IR sensitive monochrome security camera and IR LED floodlight. Find a camera with a removable IR filter or one without one made for IR use.

For one, you can take a moto-tool and cut a straight slot in the head of the screw, then use a flat screwdriver in your new slot to remove it. This is a lot of work but on a frozen screw it's effective.
For another, you can usually grab the sides of the screw head in a pair of needlenose pliers and rotate it out. This is especially true of the hard drive lids, and is my preferred method (since I carry a needlenose on my belt.)
For another, you can sometimes wedge a flat bladed screwdriver right in between the points of the star shaped head (tipped at the appropriate angle). If the screw isn't extremely tight, this is fastest, but you run the risk of damaging the screwdriver if it is tight.
I typically loosen all the screws with the pliers first, then spin them out with a flat blade.
Finally, remember that it's just a broken old IBM DeathStar drive. You don't have to be kind to all the pieces. Use a screwdriver as a pry bar and separate the sheet-metal lid from the aluminum drive housing. Make a hole big enough for a pair of pliers to grab it and the lid will tear out of the way fairly easily.
