Salvaging magnets from a defective HDD

[@jp040759]

I do this all the time. Those super strong magnets are impressive.

I built an alarm clock out of CD4017 decade counter ICs and the alarm uses a hard drive actuator arm striking a bicycle bell, so that's one thing you can build with these.

I use those plattors to coffee cup tray :D And magnets I use to hold crews for project machine.

[@basroos_snafu]

Fair enough you're salvaging the magnets, but what are you going to use them for? Making a MagLev scale model?

[@notnecessary7730]

For the fridge of course.....

[@DrCassette]

These are indeed some good whiteboard magnets, powerful enough to not constantly fall off like the normal whiteboard magnets often do :D

[@basroos_snafu]

@@DrCassette Now I want a fridge too...

[@benbaselet2026]

At work we usually throw them up high to steel surfaces and then let someone wonder how the hell we are ever supposed to get that thing off from there.

[@basroos_snafu]

@@benbaselet2026 Then I might as well have a ceiling mounted fridge.

I have had an interesting experience with magnets from hard drives. After using them for a while the lost significant amount of their magnetic properties. Not sure if that the case with all of them.

[@DrCassette]

Did you drop those magnets, or were they exposed to vibration, or extreme heat? That could have demagnetized them.

[@fgtujhxf85]

@@DrCassette I cant quite remember, it was quite a long time ago.

[@benbaselet2026]

New ones have such puny little magnets. Proper 15krpm SCSI drives from 15 years ago have waaay beefier ones :-)

[@DrCassette]

However, those magnets are best left in place as those old SCSI HDDs apparently are quite valuable now ;)

[@thedude8046]

Are those 🧲 strong?

[@DrCassette]

Yes, these are NIB (neodymium iron boron) magnets, they are very strong.

I dunno, something about this video attracted me to it. 🙂😃😅🤣😄😂😆😁
