Here's Instructable on how to recycle old computer Hard Drives into very original looking WALL CLOCK.
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Materials and Tools Needed
Tools that you will need for this project are:
1. Drill - I would suggest small DREMEL type drill with bench press.
2. Some Drill bits
3. Kit of Screwdrivers, type and gauge of screwdrivers may vary depending on Hard Drives you use.
4. Small Pliers
1. Old computer hard drives, preferably 3.5 inch. The more you can source the better.
For this particular project I used 12.
2. Standard basic quartz clock movement, you can buy this at local electronics shop such as Maplin in UK, or butcher some other wall clock. For this project I have chosen to buy part as it only cost 2.99GBP
Step 2: Disassembling Hard Drives
First of all you have to undo screws as shown in picture below, after that you'll be able to remove one or two shiny disks (platters) and some thick aluminum washers.
Underneath you'll find Hard Drive Motor, this usually attached to HDD case using 3 screws.
You can also disassemble Actuator Mechanism, there are 2 very powerful magnets for your future projects.
Step 3: Assembly
First of all you have to assemble solid base, for this I have chosen to use Hard Drive Motors.
Join the motors as shown in the pictures to form desired shape of your clock.
I have created a circle, since it's most common shape of the wall clock.
To create the "face" of my clock I have used aluminum washers or spacers that separate hard drive platters. To join them you'll need drill press and small gauge drill bits.
So, hole in each washer and join them using small self-drilling screw as shown in the picture.
The rest is in your hands, create shapes you like, use as many rings as you have, the more you use For my clock I have chosen actually reflect HOURS using rings. For 3AM/PM I've used 3 rings, for 6AM/PM 6 rings and so on....
Step 4: Fitting Quartz Clock Movement
To attach QUARTZ CLOCK MOVEMENT I have used hot glue. Of course before sticking anything into place you have to measure things accordingly.
I have also sprayed quartz movement with silver car paint...
Step 5: Finishing Touches and Setting TIME
The last thing you have to do is attach clock arms and set the TIME :)
