SkyTracker

Code and design files for a motorized barn door tracker for night sky photography.

Hardware

Status:

  • Current mockup should be workable assuming the stepper motor does not change as the design progresses.
Concerns:
  • Vibration induced by stepper motor.
  • Coupling of stepper motor shaft and threaded rod.
  • Power requirements of stepper motor could lead to a last minute stepper motor change.
TODO:
  • Measure T-nuts, make sure holes in mounting boards are the correct size.
  • Waiting on circuit for the following information:
    • Circuit mounting constraints (Size, mounting holes, power supply)

Circuit Design

Status:

  • Not started.
Concerns:
  • Power consumption of stepper motor, need to create designs to determine alternatives and solutions.
    • Power consumption vs. torque, how much torque is going to be required to lower the camera?
    • Stepper vs. Servo w/ regards to vibration?
  • Power supply battery vs. AC Power, Wattage being consumed by steppers for possible deep cycle battery -> Power Inverter or DC-DC power supply -> Stepper motor supply.

Software Design

Status:

  • Not Started.
Requirements:
  • Drive stepper at a set rate to match sky rotation
  • Quick move modes for moving platform up & down
