Enctest
I made this project as a side quest for a company. It was used in the production for fast and reliable testing at the end of line.
I got a 1 (A) for it and was finished one semester early. It is a test utility that can test motor encoders. After my prototype was finished I worked for a firm for who I developed it further and produced a small series. It is now used in the industrial production and quality assurance. The work for my graduation consisted of the prototype, a 50 page theoretical document and a user manual. 
This is an encoder module mounted on a DC motor.
