Harddrive Speakers
paranoidia writes "Ever get annoyed by the loud noise your harddrive makes? I bet you never thought of actually using that to your advantage. A friend here at CMU actually took 3 broken hard drives and got them to spin at certain frequencies outputed by his computer. So in the end, three harddrives are actually now speakers! There are videos and a few pictures with explanations onto how he did this wonderous thing."
first post suckas!
Damn jews will be the end of civilization. We must destroy the black-hearted race before they steal everything.B>
His drives don't play music, they play along with music, and don't even sound that impressive at that. It is creative, though, I'll give him that.

Wow, I'm glad I got up this morning and rushed over to my machine to check Slashdot and see what the latest important news in the OSS/FS world...only to find it was a few harddrives making noise :-/
Now we have the SLASHDOT effect! :)

The 10K drives in my G4 and the 15K drive in my SGI Octane are pretty loud, but it kinda makes sense... faster spinning SCSI drives have never been known for their whisper operation, more like a jet engine.
That said, most of my other drives in my Windows and Linux PCs are fairly modern 7200 RPM drives. My two newest Maxtor and Western Digital drives are so quiet that I sometimes forget they are spun up. Almost cool to the touch, too.
Now if only 7200 RPM drives would come with 7ms seek times. Heck, the drive in my O2, a 7200 RPM SCSI Seagate Barracuda ST318416 from almost 2 years ago has an average seek of 6.0ms with a max full seek of 10.5ms... a good 3ms faster than the fastest 7200 RPM IDE drives of today.
Umkay, I listened to that Matrix (sound) ... i couldn't hear anything but a *schhiiereiiiereiri* sound!? Yeah I know, my sound deamon is simply not good enough ...
IMHO, some people have got too much free time.
Life sucks.
Well, instead of going for the first post, like I should have, I decided to pull the pics and txt and a vid or two from the website. I submitted them to HardOCP.com since they are down with these cool ass mods as well. Its up to them to post it but if you go to check it out and its dead or gone, try HardOCP.com. No gaurantees as of yet.
If neither work - bookmark this page and come back in a week. It is well worth the check out. Its amazing.

I cant stand computer noise anymore. Maxtor and WD drives are almost quiet enough, but as you point out they are seriously lacking in latency. IDE isn't that great bus either (no disconnect ability). Desktop computers also have a problem with noisy power sources as well.
Anyway, I finally . A totally silent laptop is the way to go.
The owls are not what they seem
I remember the program that played "Bicycle Built for Two" on the 1541 disk drive motors. Sound quality sucked, sure, but DAMN, that was cool.
Ah memories of my Disk II swirl in my head. I recall someone wrote a program to swish the stepper motors in a way approximating the sound of intercourse.
I'll bet this dude's school is going to have a bone to pick with him and slashdot, 10 different meg-sized DivX movies. "Uhh. Look at the server activity, Bob" "OH SHIT!!"
I wonder if you can scratch the drives :)
Seriously though, out of complete ignorance, does this work in a similer fashion to vinal record players?
I also once wrote a machine code program that polled the cassette player read-bit (dont remember specifics anymore) and changed the background color and clicked the audio for every bit change. It was pretty cool to play your tapes "digitally" on a C64.

I had a maxtor hdd refusing to spin up and it was making funny beeping noises.
I thought that the harddisk came with speakers, but later on realised that those "beeping" sounds were caused by the coils!
I hope he knows that if he touched those PLATTERS he's going to DIE!
Those platters are HIGHLY TOXIC, otherwise they wouldn't lock them away in those air-tight drives!
You know, I love telling that to computer newbies. Someone told me that a while back, and it was so funny I had to further propogate the rediculous myth. I'm amazed how many people fall for it.

Does this "DJ Afroman" have anything to do with Afroman the drug dealing rapper? Download some of his songs on Morpheus, specifically Crazy Rap, and you'll see why I'm concerned with the legality of hard drive speakers.
Okay, this seems like an appropriate place to post my bewildered question :)
Is this really for real? I for one have had an opportunity to use a vibrator, and while I did notice that the pitch changed depending on how much resistance was applied to.. well, while I could change the pitch, I can't imagine that I would ever get a chord. Ever. Or emulate a french horn or a 120-piece orchestra.
So how the hell is he getting "Star Wars" out of those things? Is it really possible that vibrator, used by the most skillful hands imaginable, could be made to play "Invasion of the Gabber Robots" during foreplay, funny robot voices and all?
Three pitches, I could easily buy - some kind of cheap MIDI substitute. Human voice? Someone has to explain this better. If my girlfriend's vibrator starts talking to me, I'm ending it. Well - I guess that would depend on what it said.
"Beware he who would deny you access to information, for in his heart he deems himself your master."

Here's the discussion you wanted anyway: Symphony for Dot Matrix Printers. If I remember correctly, there was a second Slashdot story posted about this site - either a duplicate or a Slashback article. Finding that is left as an exorcism for the reader.
I thought the recent article about the souce code for the Linux kernel being read over the radio was the dumbest possible techno-gimmick possible. Obviously, I was wrong.
Reminds me of a simpsons ep i saw a few days ago, marges old boy friend is now a millionare b/c he invented a modem that converts the old analog squeeks into easy listening music.
Carpe meam simiam!
I am actually shocked whenever I here a noisy, clicking hard drive, even though I know it is the norm. I never buy anything but the cheapest Maxtor I can find, and they don't make any noise I can discern over the computer's fan. Why PC manufacturers use anything else when Maxtor is usually the cheapest is beyond me.

Didn't those disk drives contain their own processors? I recall hearing they were often programmed to format disks very quickly, so I guess they could be used to play those tunes while the C64 works on something else.

Anyone remember the Gadaffi virus on the Amiga? It was rumoured that it played strange tunes using the drive stepper motor. The info on it here backs this up, but I've never seen the virus in action... anyone care to elaborate?

Yup, but it was of course not really healthy for the drive. :)

These tunes got so popular at least in swedish computer mags that they gave *huge* program listings in the mag with literally tons of DATA statements, like
110 DATA 201, 34, 129, 123,
etc. Of course since it was the only way to program in machine code from BASIC... *shudder*

We have a kickass connection here. I would be very surprised if /. took it down. Half the eastern cost bandwidth at one point or another passes through CMU. Cert is here, too.
Yeah, they had thier own processor, but they were NOT fast at formatting a disk, it took about 80 seconds, then you had to flip the disk over and format the other side (if you were so inclined to use double sided disks).
Oh, and copying a disk was lots of fun, considering that the memory could only hold 64K chunks at a time, and the disk held about 180K per side, I think (it was measured in blocks rather than KB back then). You had to keep switching the disks back and forth to make a copy of a full disk.

Well. You do realize that regular speakers only work by vibration, don't you? You get sound out of these the same way you get sound out of single speaker cones, by moving them through each individual sound wave.

I know the head in a floppy drive doesn't work the same way as it does in a hard drive, but I wonder if there's enough similarity to get the same effect? My FDDs seem to die more often than my HDDs so I'd try it with one of them before I take apart my hds
BTW- Yes the slashdot search engine is a steaming pile of shit. They really should buy one of Google's fine products or something.

Someday, I'll have a real sig.
Ok, a Beowulf cluster is multiple COMPUTERS (or at least partial computers) that are linked together to do distributed computing. A RAID Array is multiple HARD DRIVES linked together to emulate one large hard drive with redundancy. There's a big difference.
I don't know...a Dolby Digital EX or a DTS sound played through 6 sets of these could be cool (and über geeky)...don't know about the ".1" though. I think you'd have a hard time finding a hard drive head driver that could produce that low of a frequency!
-James
We used to do this with our Commmedore 64 floppy drives, or at least something close. You could control the and make it play a crude melody.

Didn't those disk drives contain their own processors?
Yes, they had an on-board CPU and RAM so it was possible to run custom programs on the disk drive. I had one disk-copy program that worked this way; it would automatically copy disks from one drive to another, without involving the main computer (the drives were connected by a daisy-chained serial bus, so you could even unplug the computer from the drive chain once you'd uploaded the program).
Yes, if you insert the right stuff into the job queue.

There was a program called "drivemusic" that made the internal floppy drive play the "Condor Pasa" tune. IIRC it basically moved back and forth the head using some sort of pulse width modulation. Sounds incredible, but that marvellous machine gave the developers complete (and incredibly responsive) control of its underlying hardware.
A Beowulf Raid 5 Orchestra of these things!
The sound being produced is not the related to the noise some hard drives make. He's not spinning them at particular rates to get different sounds (which would only allow him to produce one frequency per platter anyway). He's vibrating them, just like regular drivers. Still a cool waste of time, but not the least bit what the posting indicated.
His site has loads of other goodies such as this (stupid mods) or again this (really cheap mods)
Back in my C=64 days, I remember finding this program that played a song ("sailing, sailing, ..." if my memory serves me correctly) using the motors on the C=1541 disk drive. Pity that just a few runs of the program would trash the drive. Ah, nostalgia!

... the amiga is so old that a HDD would be the size of a small suitcase. Yet this dude says that it's the smallest drive.
Don't ask me, I was too skint to have an Amiga with a hard drive, or even an amiga with a floppy for that matter, I had to stick to the spectrum (and the tops-20 machine at college - only 3 people allowed to use emacs at once otherwise it'd kill the machine!), but maybe this is a typo or this is a little bogus.
So: how big WAS the amiga hard drive?
Note to ACs: I won't mod you up, even if you are being funny or insightful. So take a chance! It's not real life!
wait so im confused.. is the music really coming from the hard drives or is this a joke...
He even did a hack(parody) on slashdot.
From what I can see the drives are not spinning at all, he is just using the voice coil of the drives as a speaker.
just for the record, this is probably the most fucked up thing I've seen in a while !

I bet this technology could be used to move a cone of paper or other stiff material, which would move a large air mass and create clear sound vibrations, thus reproducing sound...
Nah, too crazy...
Seriously this is very cool and reminds me of the folks who put an AM radio next their Altairs (or whatever it was) and ran different instructions to create different frequency interference, thus creating music.
What I'd REALLY like to see is the microwave interference from a GHz PC fucking with a cordless phone or something, making it ring....could it be done?
Back in 1982 or so, I remember pr0n software for the Apple ][ that used the floppy drive (O, the irony!) for the sound effects. Same principle: it did it by moving the head (hee-hee!) back and forth.
And the brethren went away edified.

"I guess it would help if I said what this is. Well, for all you cheap guys who have never played Doom before, this is my rendition of a scene from the final stage of Doom II.

It is constructed in 3d out of cardboard, and has circuitry such that when I push the monitor power button things light up. And yes that is my beloved Donna in the background of the first picture."
I used to do this about 8 years a go with old 5 1/4 floppy drives that i scraped. or just use a steper motor from anything.
I was bored in the 6th grade and took to hooking stuff up to my stereo. onetime i hooked up a laser diode it was cool for a couple min before i turned the volume up to loud and fried it.
I used to hook leds, motors, laser diodes and nearly anything i could find to my stereo. The stereo died a year or so later turned it on one day and smoke was comin out of it. Not something i would recomend todo with anything that wasnt bought at a gragesale for 20$ but interesting none the less....

Way back when, the printer us poor students were using for batch job print outputs was an HP Corvalis mumblemumble (can't remember the exact model name). IIRC, the printer was not a dot *matrix*, but a dot *line*, i.e. it was a row of pins that ran the width of the print line. No moving heads, part of the whole line would be printed in one shot. (If the mylar guiding band slipped off its control gears, your 200 page listing would be condensed in this black block 2/3rds of a page long.)
(Ouch. Bad description. But bear with me.)
Anyway, we all noticed the different pitches the printer would make depending on what was coming out. We all could make the beginning of a print job and the breaks between the different sections (jcl, code listing, code input, code output, billing info, end of print job -- more or less) without even looking at the printer.
So, one day, some smartass spent the whole weekend typing this weird HP-2000 BASIC(1) program that was that did not make any sense (mostly PRINTs)... But, when ran, made the printer screetch out Beethoven's 9th!!!
I wonder how long it took him to figure out what line pattern mapped to what note.
Hey, why print the Mona Lisa or Einstein's head (remember those old ASCII posters? Boy, was there a hot trade of the card decks to output those!) when you can litterally print music?
---
(1) The college used an HP-2000 as a front-end for the mainframe. If not using punched cards, you'd be typing your stuff on an ADM-3A's hooked up to the '2000 using some homebrew line editor to enter you job (jcl, source code & program data) and then used some magic program to submit it to the 3033 (? or was it a 370?) that was doing the actual processing.
What, just like you don't have to do with 'diskcopy a: b:' from a DOS window?
Would have been a lot nicer if they'd used base64 ...
It's not the platter spinning that's gonna give you any sound. It's the actuator!! The thing uses a VOICE COIL for atheist's sake!

Come on, man. Having sex with a girl is something almost every guy does, dozens of times over his lifetime. It's kind of like, I don't know, getting drunk, or eating a really tasty manicotti - fun! pleasurable! but mundane.
Now listening to the theme to Star Wars emanating from your girlfriend's nether region with the help of a wonderful piece of technology you've ingeniously turned into a speaker using only your amazing dexterity and skill - that's something almost no one ever gets to experience in an entire lifetime. I'm not even sure it could be done. Maybe with a lifetime of meditation and dedication to Zen?

First, I could/would never do this, so congratulations. However, it does sound (I know, your microphone sucks) like there is a lot of the normal whirring and clicking of a hard drive laid over the music. Have you given any thought to cancelling this noise out, by perhaps writing something that would play a constant (or variable with rotation speed) noise opposite the humming?

An engineer who shall remain nameless (cuz I just know what'll happen here if I bring up where I know him from - the Coleco Adam - and yes, there were some very cool things about that machine for its day)
Anyway, he was charged with a program that would make sure the floppy drive was operating before doing other things, so to put it thru its paces, he had it access tracks in the correct order (and therefore musical pitches based on spin) to play "Mary Had A Little Lamb" - hear the tune - everything's OK!
That - um *feature* didn't make it to 1.0 though.
"Win treats sysadmins better than users. Mac treats users better than sysadmins. Linux treats everyone like sysadmins."
Years ago, say in the early and mid 80s, Texas Instruments made a line of computers called Explorers, derived from the Lisp Machine of MIT AI Lab fame. The engineers at TI were pretty sharp, and had a good sense of humour, too. Upon power-up, the Explorers would go through a battery of self-tests which included (emphasis for relevance to the current story) seeking the heads of the *running* disk drives at audio frequencies to create a rising tone followed by a falling tone: whoooeep-wheeeou. I was at MIT at the time, and TI gave us a heap of these machines since they used the NuBus, which our group (Real-Time Systems , headed by Prof. Steve Ward) had invented. We were all a little suprised when we heard them make that noise, but became, in truly geeky fashion, completely impressed once we figured out how they did it!

Having sex with a girl is something almost every guy does, dozens of times over his lifetime.
Dozens of times over a lifetime, eh? Yup, I'm at Slashdot all right.
Ianal, and I realise that some quite clever engineering would be needed in terms of timing and frequency, but being a writer and not a physicist I can't think of any reason why this wouldn't at least reduce noise, if not negate it completely.
So, will somebody who actually knows stuff respond and flame me for being an idiot and making suggestions on topics I only have a marginal understanding of?

If I recall, the 1541 had a 6502 and 14kb of ram. That was ironic, because I used it with my VIC-20 "computer" that had a 6502 and 3.5kb of ram.

Try it! It makes a really nice analog whirrrrrrring sound.
oh god, I laughed so hard now i'm crying and people are looking at me funny, why do I insist on visiting /. in public places!!
Well, after viewing this, I just HAD to try it out. =)
:)
I grabbed an old scsi maxtor 200 meg drive, and began ripping its guts out.
Now, this old drive is kinda clamshelled inside of the case,
with the heads, actuator, platters, and motor all in a case within the case.
I probed and probed the connectors on the ribbon cable attached to the heads,
Finally I found two with low enough impedance to be the coil for the actuator.
Next I grabbed some old 20AWG crap speaker cable and soldered it onto the the ribbon cable.
After checking again with the multimeter to make sure there were no shorts I hooked it up.
To my amazement, it actually worked!
After a few seconds, I could feel the drive getting quite hot.
So I grabbed a tiny heatsink I had lying around, and thermal epoxied it onto the exposed part of the.. err.. voicecoil
Much cooler now.
As for the sound, the quality of this "speaker" is quite poor.
Its alot like listening to overdriven headphones from across the room.
Then again, at some high frequencies, it actually rivals my Dynaudio home thearter speakers.
Simply amazing!

A ScanJet 4c (I think) we got back in 1994 had a Jukebox.exe program on the driver disk. It's been a while, but I believe it let you play MIDI files on the scanner stepper. Quite clearly, too. I think they yanked the program later on, though, I've never been able to find it again.

WTF? U dont wanna come to CMU... I've been here almost 2 terms and I wanna get out! leeeeeeeave!!!
Now it would be something if we could use those Zip drives that died the "click death".
A looooong time ago, at a college not too far away, 1/2 inch tape drives were in very common use. The capstan motors were capable of small movements and could be reversed quickly. IBM had a demonstration set up at one of our E-Days programs with a paper speaker cone mounted on a small stick. The stick was clamped to a capstan and they had a program running to play quite acceptable quality music. IIRC, they could even control the volume. Since this was over 30 years ago, I don't remember all the details but I was impressed at the time.

If you have a close look at the label (see here or here: sorry, couldn't find larger pictures), the last character is slightly different from the first (it does not have the oblique little dash like the first, so it is not a ``1'' digit).
OTOH, all the Commodore user documentation reported it as 1541...

Among other things. Here at the U of Wisconsin - Madison we use use them as sleds.

Do you even know anything about perl? -- AC Replying to Tom Christiansen post.
My next science fair project was building a multiplatform (Apple II, TI 99/4, Vic20, Atari 400, TRS-80 models III and II) network over cassette drive cables and RS-232 serial ports for the purpose of playing games, sharing and printing formatted documents with hyperlinks, and accessing incompatible peripherals. I narrowly missed advancing to the international science fair on that one, probably because it was ahead of its time.
The judges two decades ago didn't like to admit they knew nothing about computers-- the comments I got were along the lines of "the ability to use computers is a good skill but does not constitute science unless it presents something new or investigates something less trivial," writing off my creative ideas and all the code I wrote as just the way people use computers. A decade later, the same idea was no longer called "trivial," but "the single most important technological innovation of our generation."
Go figure.
True!
Weren't older Hard Drives called "Voice Coil"?
I also recall that the giant early Hard Drives were really large, and one older computer terminology dictionary referred to Hard Drive Racing (HDR)!
It said that the washing machine-sized drives could be made to move by precisely controlling head movement, to the extent that programmers conducted 'races' across the floor of the room.
Anyone who used such equipment confirm this?

they had the symphony of dot matrix printers. i downloaded the mp3's. it was interesting at the very least. i don't think they used the printers to make sounds (like this kid did with the hard drives). i think they took the printer noises and mixed them to produce a musical piece. the printers weren't the "speakers" they were the musical instruments, like in a real orchestra you've got violins and horns and stuff. hope this helps.
please me, have no regrets.
Nope, I was wrong. The 1541 had 2kb of ram according this.

But you could do it by running an audio signal through main coil.
