In my raids, I often come to projects where old CD-ROM or DVD-ROM drives are exploited (yep: round about year 2000 is old). Especially the stepper motor, which moves the read head, is used in projects where, for example, the self-construction of a CNC station is concerned. French translation: CD-ROM avec animation vidéo intégrale ayant été primé/récompensé/distingué.
