Introduction

  • Similar to a CNC Turntable, but optimized for display/photography/photogrammetry use
  • Less torque and rugged than the cnc version, but as precise
  • Perhaps make it have white, green, and black "finishes" / plates/covers for matching backdrops?

Industry Standards

Genie

  • Geneie 2 ~300USD
    • Specs:
      • Genie Mini II Panning Motion Controller - USB Type-C to Type-A Charging Cable - USB Type-C to Type-A Female Cable - 1/4"-20 to 3/8"-16 Thread Adapter - Micro Fiber Cloth - ***Instructions - 8" Aluminum Turntable Platform - Black Background Disk - White Background Disk - 10' Shutter Extension Cable - 1/4"-20 to 3/8"-16 Thread Adapter - Micro ***Fiber Cloth - Instructions - Syrp 1 Year Limited Warranty
      • Load Capacity: Panning Load: 8.8 lb (4kg)Tilting Load: 6.6 lb (3kg) Centered
      • Maximum Speed: 360 Degree in 33 Seconds
      • Minimum Resolution: 0.005 Degree
      • Camera Mounting Screw: 1/4"-20 (3/8"-16 Bushing Included)

Existing Open Source Designs

Minimum Viable Product

  • Standard Mounting Screws
  • Make the mounting point a module?
  • "dumb" spin at a certain rpm mode
  • Remote Control Mode
  • G-Code Based mode (especially useful as a 3d scanner)
  • Small form factor?
  • Use either a nema stepper, or a hobby servo?
  • 0.005 Degree Resolution or better

Basic Design

Shell

  • 3d printed, then post processed, then painted?
  • Also modular for different colors? (or make a shell outside the structualshell for this??)

Control Circuitry

  • A Stepper/Servo Driver (only needs 1 channel)
  • IR Remote in?
  • Bluetooth/wifi in
  • USB (preferabbly usb-c)

Motor

  • Need to find max res of a stepper (driver dependant isn't it?)

Bearing

Gearbox

  • A simple gear reduction (planetary gear?)
  • Not 100% needed but could improve precision (?), and would slow speed which may be useful
