Differential pan tilt

thingiverse

Inspired by https://www.thingiverse.com/thing:2005695 at the search for a pan tilt meachnism that could give my USB- Fan a swaying motion. So that thing works quite satisfiying although the clearence between the cogwheels could bee improved if it has to bee more acurate.For my purpose it is ok. Ther are many phantastic pan tilt versions existing at Thingiverse but mostly they need to many additional parts like ball bearings etc. Here just one M4 bolt and Nut + one M5 bolt is needed. You will find all the needed files for the Arduino and the print. File 00 shows all in assembled order and is not printable. Controlled again is it via the smartphone and the remoteXY-app as it did with the satfinder device. All the electronic parts that you need, can be found in the electrical overview or the fritzing file. Update 25.07.22 : Arduino code : Bugfix- some Positions were skipped at the Autoplay mode.
