Didactic instrument created using the direct current motor and the gear system of the cd player to open and close the CD tray. The motor is used as an electrical generator, and coupling it to an oscillator circuit created with a 555, resulted in this manual electronic accordion.
it does not have any type of batteries!, the sound comes from the cycle of energy transformation.
Linear (open and close CD holder) → Circular (Gear system) → Electric (Dynamo) → Sonorous (Speaker)
This Instrument makes it possible to reuse disused or discarded objects and stimulates reflection on the creation, transformation and use of energy.
