In order to do this I will need to
- develop a menu controlled selection to switch between the two modes of the controller.
- add a connector to control a stepper motor.
- Build the stepper motor into a device that controls the rotation of a turntable.
I may just build the controller into the base of the device with a dial to set the amount of rotation before snapping a new picture. Doing this will keep the software simpler with no need for a menu to select between modes.
Doing this will allow me to place a small object onto the turntable, and then take pictures of that object from a wide variety of angles. I plan on taking dozens of pictures from a low angle, resetting the camera to a higher position and taking another set of pictures from that angle.
Then I will have to manually upload the photos to a service that will stitch them into a single 3D model. Such as autocad's 123D service. Hopefully someone will develop a package possibly based on hugin in order for we open source people to build our own 3D models in house without depending on a service that could someday start charging serious money.
