Turning Dead Drives into Speakers?
An anonymous reader writes "Why pay 500$ for Klipsch's latest speaker system? You can make something that looks way cooler for the price of a DIY amplifier and some HDDs out of a dumpster. It doesn't sound quite as good but who cares!"
Next week we'll show you how to turn a laundry basket and a speak & spell
into your own segway.
I can't find the story for the life of me, but I know it was on Slashdot a long time ago. (Does anybody else think Slashdot's search engine is a pile of crap?!?!? Of course Google wasn't much help either, this time.) Anyway, the last article was actually about using printers to play music (remember now?) but either in the story or the comments, it was also mentioned that it could be done with hard drives (and had been done for years). Pretty cool, yeah.. What about picking up the Van Eck signals from your monitor on an AM radio? That was pretty cool. Anyway. Yeah. I do some tinkering with robotics, and if you pick a bad frequency for PWM (Pulse Width Modulation), your motors will scream and whine as they act like speakers. You can use frequency modulation to make them play music and stuff too. Useless, but kinda fun to show people that don't know squat about electronics... ;)
The streets shall flow with the blood of the Guberminky.
you mean $500, not 500$.
Been there, done that. GOTTA be a better way to check for stuff thats been reposted.

Hmmm, I rather liked this mod, after having read it here. I even mentioned it about a month ago in some thread about DJ's and hard drives, having recalled reading it here. To find the link to this wondrous dupe, I simply pressed ALT-F2 from KDE, typed `gg:hard drive speakers site:slashdot.org`, and the very first hit was the article.
