On Habré lately there is a lively discussion of floppy disks. And I just excavated my handmade at home. The device is about 6 years old, so the CD is so filthy, excuse me =). Components:
Disks 3.5 - 3 pcs.
CD - 1 pc.
Some copper wire
Super glue
Scotch
Diskettes are transferred to read-only mode (to free the hole). Are fastened among themselves by flexible copper wire. The design is glued to the super-glue to the CD (now it is better to use purple DVDs :). The tape is sealed with a hole in the CD, so that pencils or pens (screwdrivers) do not fall out.
