Overview
Designed and built an electronic device that produces smooth motion time-lapse photography by precisely controlling camera movement over a programmed duration. The device allows the camera to pan or track across a scene while capturing frames at set intervals, resulting in a fluid cinematic time-lapse effect.
Design Goals
- Smooth, consistent motor movement to prevent jerky footage
- Configurable speed and duration for different shot lengths
- Compact and portable enough to use in the field
- Low cost using off-the-shelf electronic components
Build Process
The device uses a stepper motor for precise angular control, a microcontroller to manage timing and step sequences, and a custom-built chassis to mount the camera and motor assembly. The electronics were designed to be battery-powered for outdoor use.
Key design challenges included minimizing vibration during motor steps, ensuring the camera mount was secure under load, and programming smooth acceleration and deceleration curves to avoid abrupt movements at the start and end of each shot.
Results
The finished device produces smooth, professional-looking motion time-lapse footage. It has been used for landscape photography, capturing sunsets, cloud movement, and long-exposure night scenes.
