Linear and Rotational Actuators
This project page describes prototype linear and rotational actuators. They can be used for any purpose that requires slow movement of light-weight hardware.
We will explore using the actuators for timelapse photography. For this application, an Arduino will alternate between moving the camera a small step and triggering the camera shutter.
After some further development and testing, we will sell a kit version of this project.

Assembly instructions
This was just a prototype. We haven't produced a final version yet, but hopefully will in the future. At that point we'll provide assembly instructions. Contact projects@manylabs.org if you have assembly questions.
