This is a 2.5" HDD clock I made from a dead external hard drive. I used a 2.5" drive instead of a 3.5" drive as in the UK it is very hard to find clock movements that have a long enough spindle to go all the way through.

This is my first instructable and I am 14, so any constructive criticism or comments are encouraged. I am entering the battery powered contest, so be sure to vote for me!

Step 1: The Parts and Tools.

The parts needed are:
1. Any 2.5" HDD
2. A clock movement, long enough to go through your chosen Hard Drive.
3. Hands for the movement.
4. An AA battery.
5. Old RAM for a frame (optional)

1. Torx t8 and t7 screwdrivers (for the drive casing and fasteners).
2. A small philips scre driver (for the drive PCB).
3. A pair of pliers.
4. A 1/8" pin punch. (for the dismantling the motor)
5. A rubber hammer. (for the pin punch)
6. A drill and 7-7.5mm metal bits.
7. Glue for the frame (optional)
8. Bolts for holding the frame (optional)

Step 2: Dismantling the drive.

You need to unscrew all the screws on the casing and PCB with the drivers, then unscrew the platters and remove them, put the in a safe place, unlikely to be scratched. Move the read heads out of the way to remove the platters, there may be a plastic or rubber stop in the way, next to the magnets in the corner, remove that with pliers.

Step 3: Drilling the holes.

You will have to put the drive in a vice, PCB side up, and use a center punch and hammer through the center to the motor, to remove the top part and core.
Chose a drill bit the same size or 0.5mm bigger than your movement spindle. Remove the top of the motor from the motor, with pliers or fingers, drill down the center, do the same with the other side of the motor, on the casing with the copper coils.

Thanks for the comments, I have added an extra step on how I added a frame for the clock made from old RAM modules.

Wow, well done good job! Especially as you are 14. It's a clock worthy of any IT geeks desk! (I'm nearly 34 and wonder if my soon to be attempted version will come out anywhere near as good!)
