Star Tracker

Provided source code, inventor CAD files (student licensed) are available. An Excel sheet to calculate the rotation speed table is also included, useful if other dimensions, threads, or motors are used. The stepper driver is powered directly with 5V from the power bank, bypassing the power input pins. My experience indicates that a Polar Finder Scope is not necessary, at least for wide-angle shots. One-Button Control: Simply plug in the USB cable. Press the first button to rotate to the initial position and start tracking. Press the button again to return to the initial position and continue tracking.
