Arduino, Raspberry Pi, NoIR camera module and 2 servos combined to a nodal point pan and tilt photsphere cam. Arduino and Raspberry Pi Python scripts are finished and it's working. After capturing the pictures I stitch them in Hugin to an equirectangular panorama and upload it to Google's photo-sphere.appspot.com to add the metadata to watch it later with the Google viewer.
Currently I am waiting for some parts from China, especially a longer flat cable for the cam. The pan servo has to be replaced by a 360 degrees servo. And I need some cheap cut / pass filters: IR cut, IR pass and UV pass filters, to be exactly. Since some filters are really expensive I am going to try to obtain woods glass.
