Tracking gear for astrophotography. Works for small focus lengths. Compatible with most common tripods. It was a test of FDM printer possibilities...
Note: I've reached more softness, building simplicity and small weight in this project.
prokladka_*mm.STL used warm-gear tense adjustment. Big tense causes waving of all gear. #include <AFMotor.h>// Connect a stepper motor with 200 steps per revolution // to motor port #2 (M3 and M4)AF_Stepper motor(200, 2);void setup() { Serial.begin(9600); // set up Serial library at 9600 bps motor.setSpeed(5); }void loop() { unsigned long last_time_point, diff; int step_period = 755; last_time_point = millis(); while(1){ diff = millis()-last_time_point; if(diff >= step_period){ motor.step(1, FORWARD, MICROSTEP); last_time_point += step_period; } }}AFMotor.h is Adafruit Microstep motor library from https://github.com/adafruit/Adafruit-Motor-Shield-library
