In year 2012 i have completed a modular motion control for moving and mounting your camera in versatile ways. Optimized for using with DragonFrame (Dzed). I implemented simple projects for light control, or motion effects during frame capture in your stop-motion animations. Motion Control "Step2Go", is a simple way for low-budget motion control with a hardware box, "Frame Control" - that control step and direction of 8 stepper motor.
