Hello everybody, Maybe someone can help me to solve this engineering problem. How you will see on the photos I need to add this little potentiometer to the big gear. It will give me the information about the position of big gear(the biggest with the hole inside). Off course it is better to instal this potentiometer inside the box, but it can be all so outside. So maybe someone has a great idea? Thank you very much! P.S. Sorry for the big size images!
