The Hard Drive Clock
GearCrave caught this one on http://www.heise.de/. Since we’re not multilingual, it was painful to try and read the specs on this amazing custom clock built from an old hard drive. So sayeth Heise.de:
“Und so funktioniert das Ganze: Der Synchronmotor, der die Magnetplatten antreibt, rastet in 16 Positionen pro Umdrehung stromlos magnetisch ein. 12 Positionen werden dabei als Stundenanzeige genutzt, nach 12 Uhr muss der Motor 5 Schritte weiter laufen, um wieder bei 1 Uhr weiterzumachen. Der Schreib-/Lesekopf, der mit einem Schrittmotor angetrieben wird, rastet ebenfalls stromlos magnetisch ein.”
Roughly, that’s telling us that this cool-looking hard drive clock uses a synchronous motor to turn the magnetic disks, which rotate to 16 positions per revolution. There are 12 hour positions (duh) but the whole thing has to move five steps ahead to tell the time past 1 o’clock.
You know, it’s funny. All this has us thinking about how digital displays threaten to render the phrase “o’clock” obsolete unless we manage to keep using timepieces with hands and faces. Like this one…
