The development of a low cost profile measurement system suggests ? because of the feature low cost ? the use of an open source control system. In this work, the authors combine a commercially available compact disc (CD) pickup head, the National Instruments NI-PCI 6221 data acquisition card, and a PC running RTAI Linux. The setup is used to scan along a CD and measure the distance between tracks. The setup will be used in a lab course by students to get to know rapid control prototyping systems and open source alternatives to expensive industrial systems.
