Abstract

A good opportunity for hands-on activities, both at school and at home, is represented by experiments conducted by means of easy to find materials or devices recycled from old and no more working household appliance (as a dc motor can be). These kinds of activities keep a special appeal and attractiveness together with a great teaching value, because pupils can repeat experiments at home proving to their parents their new acquired skills and competencies. In this work a dc motor, derived from an old video recorder, is interfaced with a PC to measure efficiency in conversion from electrical to mechanical energy.
