  1. A very cool project

    by Francesco on June 25, 2012

    In my opinion this is a very cool project!
    As an educator in Measurement Science I see it as one of the better choices to teach measurement and feedback control theories topics in many experimental laboratory classes.
    I can't wait to have my first osPID to experiment by myself and to give it to my students and see what they will be able to do with it!
