i designed this pan tilt head in the course of my bachelor thesis for media-informatics at Vienna University of Technology
The goal was to get highest angular precision for long-term timelapse photography. The device achieves a accuracy of 0.092° for tilt and 0.101° for the pan aixs. It is IP44 designed and should resist strong weather conditions if sealed accordingly.
video showing the development process: https://vimeo.com/93193071
The pan tilt head is driven by 5V stepper motors and controlled with a python program running on a raspberry Pi, the Websoftware used in the video is the work of David Lung and can be found here: https://bitbucket.org/lung/imscam
The payload for 5V Stepper motors is max 330g (10cm axial distance). If more is needed use 12V Steppers (payload unknown).
if you are interested on more details or the full thesis, fell free to contact me at [email protected]
The 3D files were specially designed to be printable on low end customer devices. The first prototype was printed with a portabee classic (500$ printer)
the second prototype was printed with a uPrint SE from stratasys
The 30x17 axial bearing and the marquardt microswitch are crucial parts for the project. If you can´t find them somewhere near you contact me.
The normal radial bearings 8x12x3,5 shouldn´t be that hard to find, look for RC car bearings.
The small axial bearing does not need to be exactly the given dimension, its on the bottom, so it can vary in outer diameter and height.
For the SMD Taster you have to cut 2 of the 4 pins and solder a cable to the others, than glue it in place. Use a long and thin cable, or it will touch the gears. The marquardt switch just snaps in place.
