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.

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

@notnecessary7730 3 года назад

For the fridge of course.....

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

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.

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 3 года назад

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

@benbaselet2026 3 года назад

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

@DrCassette 3 года назад

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