Step 4: Hard Drive

OK, believe it or not you can do alot with a old hard drive. If you have gave your best efforts to try and fix it and its completely dead you can try some of these-

1. Make it into a clock-
Yes the disc out of a hard drive actually makes a pretty good clock and it looks cool.

See HERE

Or if you think your really good, try this one!

See HERE (If you dare)

2. Use it as a fake
Now you can impress your mates with your USB hard drive thats actually made out of memory sticks.

See HERE

3.Turn it into a rotary input device-
Thats basically a wheel that you turn that controls your computer

See HERE

4. Make a tesla turbine
A tesa turbine is a thing that converts air and water motion into eletricty.

See HERE

5.Make a really strong fridge magnet
In hard drives there are super strong magnets...These make great fridge magnets!

See HERE

6.Make it into a safe
This ones pretty simple; gut a hard drive and store stuff inside it

See HERE

7.Simply Use It as a Coaster
Self-explanatory. But the only thing I would say is that if you have a USB cup warmer you could take the heating plate out of it so it would keep your drink warm!

See HERE

You missed 1 aspect that I've had fun with on my old drives, the strong magnets. There are a lot of things you can do with the magnets from a hard drive (I believe someone on here posted one called "the mother of all fridge magnets"). Never underestimate the usefulness of a strong magnet.

I was just sitting here looking at this (going 'wow') with a dead hard drive in my hands. Of course, being a 12 year old boy without tools or resources, i couldnt do anything here. Then i had the decent idea (or at least i thought so) of using it as a hair comb b/c of the little spikes. When i tried it, it actually kinda worked! So, because i was too lazy to make an instructable about it, and partly because it wasnt that instructable worthy, i'd like to give the idea to you, perhaps to even edit in into this 'ible. anyways, your choice, just thought it was a good idea. Great job!

A great article. I found that the hard drive platter inner hole diameter is 24mm and appears to be the same as a standard rubber plumbing washer. This provides an easy way to fix platters to a surface, for example a simple solar reflector http://mr-ives.blogspot.com/search/label/solar

because the washers are a snug but flexible fit, and because they are deeper than the disk thickness, you can fine tune the disk tilt . Hence you can focus in a set of platters to concentrate their reflection at one point. You can also unclip the platters for cleaning

Does anyone know how to interface a HDD just so I can get read/write access without using a microcontroller, just glue logic??

You could put the drive in an extra drive bay in another computer. Or you could get a hard drive enclosure, and place the drive in that, then connect the enclosure to another computer.

You will have a microcontroller somewhere, right? Actually I can imagine a 'dumb' recorder that will record sequentially over a disk in raw data until the disk is full.

I do not know how practcal that would be; you'd be building a state machine anyway I'd think. http://en.wikipedia.org/wiki/AT_Attachment has pointers to the documents. ATA is simple, but what about error recovery etc?

Nope, I don't have a microcontroller and I don't know to program one, I really wanted to just use glue logic.

hook it up to a computer running ubuntu root in and your good to go. I've done this with a few old hard drives I've had lying around

Know how to use arduino now but still haven't worked it out yet...
