Western-Digital WD Caviar 32500 2550MB [external link]When you pick up junk computers, you get a lot of parts that you can't really use, but are hard to throw out. Small hard drives are the most difficult thing to get rid of. When they still work you keep them around thinking someday you might need just 2 more gigabytes. When you find one that is broken, you still want to do something with it. They look so interesting inside, mostly because its the type of thing you are not supposed to open. So make a clock out of an old broken hard drive.

N.N. [external link]Using old HD Magnets to boost fuel efficiency and clean water? Once out of service, hard disks are taken to have a remaining value similar to that of a brick. If you have one disk that you can take apart, you may salvage some powerful magnets. Here is how and what you can do with them. Would you have thought your magnets can do work similar to a $90 fuel-saver or a $300 device sold for water treatment? With surplus magnets, such experimentation costs very little, but if you invest into the devices, you may be biased to justify the expense.
N.N. [external link]Have an old hard drive that no longer works? As long as it still spins up chances are you could build a clock out of your old hard drive! You will need some electronic knowledge, some common electronic components and a bit of patience. Videos of the clock in action available.
N.N. [external link]A normal hard drive clock would be using the disc as background plus the regular hands for hours and minutes, or you could lift the lid of the hard drive and drill a hole all the way through the engine and all and then mount the regular hands. Here is wall clock that only shows pieces from hard drives, no plastic hands there.
N.N. [external link]Anatomy of a Hard Disk Drive: here is a disassembled a hard drive to show you the main components you will find on a hard drive.

Misc. HDDs [external link]Hard-Disk Sound System: why pay many $$$ for the latest speaker system? You can make something that looks way cooler for the price of a DIY amplifier and some HDDs out of a dumpster. It doesn't sound quite as good but who cares!
Misc. HDDs [external link]Did you know you could build a speaker out of your old hard drive? Well as a matter of fact, a harddrive uses the same technology for its arm as a traditional loudspeaker. Just apply the right waveform and it will produce sound.
Misc. HDDs [external link]Harddisks have a pair off very strong magnets in it, Unfortunately, they are placed on a metal plate for fixing them in the drive. It's very hard to remove them from the metal without breaking the magnet. But if you know the trick, it's very easy.

Misc. HDDs [external link]Here's a project that uses some of those dead hard drives you've got lying around: build a 15,000 RPM Tesla Turbine using hard drive platters.

The fluid spirals inwards and is exhausted through ventilation ports near the center of the disks.

HDD Eyez [external link]ON/OFF blinking hard-drive LED can get quite annoying sometimes or it doesn't seem to fit the overall theme of the case or a project. Why not make it smoothly fade in and out when there is some HDD activity? These following steps will show you how to do just that easily and with only small amount of money. In short: We receive pulses from motherboard's HDD LED header. We get the pulses by removing the wire that goes to the original HDD LED and replace it with our own wire that leads to our circuit.
