Simple film to sound device

16mm sound-on-film visual sound patterns

To test the sound-on-film-strips I will be making for my new project “Visual Sound Patterns”, I made a testing device. I used a piece of film from another project since it has alternating black and transparant frames, which will work to create some sound.
In the end the best way seemed to replace the hand crank I made earlier with a drill, but it works..
