360° pan 180° tilt head for webcam and small DSLR

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]
