Stir plate from an old Hard Disc Drive

Hi all guys,

did anybody try to make stir plate from an old hard drive. I was thinking of removein one of the plates and put magnets on one of the remained plate.

How will you bypass the electronics to force a constant seek/read so the platters constantly spin? A power source is the easy part. Problem is that the platters are not always spinning. Hard drives made in the last ~10 years have power saving built directly in to the Circuit board on the bottom of the drive.

I'd be interested to see one though. I love to combine hobbies!

Well, as I have seen, there are two types of of hdds concerning motor type. Older types use motors with four wires which are no that hard to run as I have seen. The idea is to use custom as simple as possible electronics to drive motors. The only doubt I have is what if spinning rate is to high.

5400RPM is likely too high, but the electronics control this. If you bypass the electronics, you may be able to control the speed.
