Slide & Pan
This project uses two stepper motors to create smooth cinematic motion for capturing video or timelapse photography. You can use it to automate both trucking and panning for beautiful compound camera motion. It features a 1.3in TFT screen for displaying a user interface and a rotary encoder for controlling the stepper motors.Â
It's powered by an Adafruit KB2040 running CircuitPython. The TMC2209 stepper motor drivers offer smooth and silent micro stepping.Â
The software features a mode for capturing timelapses and a one shot mode for filming video.
DIY Motorized Slider
3D printed parts support two pieces of aluminum extrusion. A timing belt and pulley wheels are used to slide the carriage along the profile offering about 16 inches (40cm) of travel. A second motor is dedicated for panning offering a bit over 180 degrees.
A custom PCB reduces the amount of wiring connecting the microcontroller, TFT display, buck converter and two stepper motor drivers. It runs off a 12V AA battery pack making the build portable for filming outdoors.
Crank It!
Use the rotary encoder to set the start and ending positions of the panning motor. A 3D printed rotary handle lets you crank the motor making an intuitive interface for setting the panning stepper motor.
This learn guide assumes prior experience with electronics, 3D printing, mechanical engineering and videography. It is not recommend for beginner makers but is achievable with patience and the willingness to learn new skills.
