Step 1: Meterials

i use meterials from printer,hdd,cd rom.

1,2 are from a 2.5'' hdd

3 is from a cd rom

4 is from a printer

Step 2: Disk Holder

  • place the ball bearing to the axis (must be fit perfectly)
  • add instant glue carefully
  • place (the other thing with the screw) (must be fit perfectly)

Step 3: Bearing Holder

  • place the motor
  • make a paper mold and fill it with hot glue (attention to the ball bearing)
  • place off the paper mold

Step 4: Cover

  • screw 4 screws (adjust the right height)
  • place 4 magnets at the top off the screws
  • find a nice plastic for cover and glue it with hot glue to the magnets

Step 5: End

  • connect it with a power supply.
  • the motor must run opposite the disc's screw

this runs on 32v (printer's power supply/motor)

    i would guess that the melt glue that is used to hold the axis would get warm from friction and get out of shape?

    A more heat stable solution in the same spirit is some self setting silicone rubber perhaps, (or a piece of acrylic with a hole drilled).

    Otherwise I like the project a lot. Good job!

    Nice idea, though a simple gear would help to lower and hide away the motor and while you are at it, a suction fan underneath the board to avoid the dust getting everywhere would make it just perfect.

    one problem i had last year was cutting the same width a few times, a few holes to mount a guide (a metal piece you'd mount a cd drive with in a pc does the job) helped with that.
