This Instructable shows you a new way of repurposing obsolete technology to make a cool looking fridge magnet that can also be used as a wall decoration/stud finder.
Step 1: Find an Old 5 1/4 Floppy Disc Drive From an Old PC.
The component we are looking for is the Stepper Motor coil assembly.
Step 2: Time to Deconstruct This to Extract the Coil Assembly
Start by releasing the plastic clips with a screwdriver or some other tool such as a paper clip etc.
Separating the metal covers is made easy with the tool I posted previously, alternatively you can use any slim prying tool . Once you have the covers off, you will need a #0 philips screwdriver and a #1-2 philips screwdriver to expose the stepper motor.
Step 3: Remove the Board That Powers the Disc Stepper Motor.
Use a Flat/Standard Screwdriver to remove the top of the stepper motor. Make sure you are carefull to stay away from the stepper coil assembly as you pry the cover away. I find that the cover and the Circuit board has to be destroyed to remove it.
Step 4: Extracting the Coil Assembly 2
The First picture shows that the circuit board has been broken. This picture also shows that the stepper coil cover assy has been destroyed . In the second Picture you can see where the #0 philips screwdriver is needed. Pic. #3 shows the Stepper coil assy. on it's own.
Step 5: Stepper Coil Assy... Meets K Razy Magnetism.
There will be three thin enameled wires that connect the Coil assy. to the circuit board. Tear the coil assy. away from the circuit board. Then add a high powered magnet to the center and stick it wherever you want.
Step 6: Wall Deco's
Just an example of how these look stuck to the wall.
