Equatorial camera motor mount

thingiverse

This is my state-of-the-art astrophotography tracking system, a precision traveling equatorial mount that rotates its turret with unparalleled accuracy. The turret rotates 360 degrees in exactly 23 hours, 56 minutes, precisely matching the sidereal day. The ball bearing groove requires careful preparation - it should be filled to the brim with precisely 4.5mm metal balls from a BB gun, and then secured in place using the small plug provided. At its heart, this system relies on a powerful 28BYJ-48 stepper motor that operates at 5 volts, paired with a sophisticated driver circuit based on the highly capable ATTiny-85 microcontroller. To achieve optimal performance, it is essential to print the turret with robust supports. Similarly, when printing the PCB-cover, it is crucial to use supports for the upper rim - simply flip the model upside-down and print as normal. For those interested in delving deeper into the system's inner workings, I have made the code and electronics available on GitHub at https://github.com/lboclboc/CameraMotor.
