that’s a big ol’ “f u” to digital forensics
Is not fair!! We invented this device first, we want an indemnification for our invention. jojojo
Ok, this looks legit awesome. I’ve taken apart a fair number of HDDs in my day, but never tried to turn them into something useful. This is something I will definitely try.
Although, on second thought, I can’t imagine it gets very much torque. Maybe good for little grinding projects, but probably not useful for anything serious, like sharpening gouges or sanding larger projects.
Yup, tried building one, no torque at all. I believe it could have thrown those sparks in the pictures, but only for about half a second before the motor seizes.
You would use a light touch to sharpen a knife like that anyway, so I’m not sure a lack of torque would be very problematic.
Did you try it with higher voltage? I know the consequences aren’t good, but it might give enough power to make it practical.
Thanks, zimboptoo, I was also so excited and you have spared me the grief. I’ll keep wondering what task a lightly loaded spinner could do, though. Perhaps some sort of fine polishing, with a stand to hold the object?
Probably the easiest way is to go the other way–put power of some sort on the shaft to get electricity out of the motor. A hamster wheel was mentioned, but you’re not going to get much useful power out of the motor, regardless.
I’ve also seen drive platters retasked as Tesla turbines:

That depends on whether you consider downloading CP an error.
haha
you might as well destroy your whole computer then.
Abby can still find it.
or Penelope Garcia.
At that high speed, the friction and heat developed will burn the temper right out of the steel, rendering it useless as a cutting implement. I had to educate my wood shop teacher on that fact some 20 years ago when he sharpened chisels on the bench grinder. That’s why powered sharpeners are low-speed and usually water-cooled.
I see no sign of a cooling bowl, so you’re probably right. I’ve seen the water cooled ones, they do look like a good investment for someone doing lots of woodworking.
You can use a bench grinder, but you need to make light, small cuts so you don’t overheat, and have a small bowl of water nearby to dip it into. Seen my dad sharpen wood chisels like this(quick way to get rid of really bad nicks and such before a final honing), though last time I saw he was just touching it up, and used a whetstone.
Looks like he’s adjusting his files the manual way.
Both on and off the drive.
“Hello Diane. You have spent your life not caring about anybody else than yourself. Now, it’s time to redeem yourself and realize how important is life. Use that CD drive to sharpen that knife and get the key to door from your eyeball socket before poison fills the room. you have 60 seconds.”
Well hello Jigsaw. Unbeknownst to you, I am a practicing contortionsist and magician. I always have a spare key in my “cheek”.
When do I get the cake?
The cake is a lie
My daughter’s hamster’s hamster wheel squeaked. Oiling the “bearings” did not fix. So: split open a dead HDD, glue the wheel onto the motor spindle, glue the whole assembly onto the wall of the hamster’s habitat, et VIOLA! no noise! Unfortunately she went to college before it occurred to me to add power to the thing. Yeah, hamster centrifuge!
(better yet: somewhere on the web there’s a design for a high-efficiency generator based on a hamster-powered wheel.)
The hamster went to college? Or your daughter?
Ooooh! Post that one!
Awesome!
Format C? I’l show you “Format C”!
I had a bunch of old hard drives (some dead, some working) that needed the data destroyed on. So I used one of the working ones to spin the platters and a old screwdriver to do the grinding. Then we just dumped the platters in the trash when we finished. I doubt anyone could manage to read the data.
Bringing new meaning to defragging a file.

=))))
i’ve taken apart a few old maxtor hard drives. with their heads removed they dont seem to spin down so i stacked them with platters from other small capacity hard disks and they make excellent gyroscopes
I LURVE IT!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Why didn’t I think of this?
