  • I have two ideas on how to make it work.

     

    DIRECT DRIVE MECHANISM (Sony Walkman Disk Drive)

    1. Use a single motor with a 3D printed gear to drive smaller gears attached to the Nipkow Disk shafts.

    2. The gears ensure that the Nipkow disks remain in sync and at constant speed as they rotate.

    MANUAL TUNING W/ ANALOG MAGIC EYE

    1. Use two motors to run each Nipkow Disk independently.

    2. Add an LED/Photodiode to the bottom of each Nipkow Disk in order to control a RED or GRN LED.

    3. As the outermost hole passes the LED/diode, it will cause its respective RED or GRN LED to flicker.

    4. The LEDs flicker frequency will illuminate a specific portion of a color gradient printed on a transparency above it.

    5. This will create a needle effect, allowing the speed of both disks be adjusted with pots.

    6. The motors can also be disabled momentarily, with a button press, to allow one disk to fall behind and hopefully sync.

    7. Then it will only be a matter of bringing the needles together and to the center of he indicator.
