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."
