Pédale de sustain pour clavier numérique
- *Description du projet : Mon projet est de construire une pédale de sustain pour un clavier numérique yamaha.
Une pédale de sustain est la pédale du piano permettant de continuer de jouer la note pendant un certain temps lorsqu'on relâche la touche. Sur un clavier numérique, il semblerait qu'il s'agisse d'un simple interrupteur relié à un jack 6.35 mm. j'ai donc designer la pédale sous OpenSCAD pour ensuite la découper au laser. Puis pour faire interrupeur, je relie un fil sur un vis sur la pédale, juste au dessus d'une plaque en métal sur le support, elle même reliée a l'autre fil (photos à venir). Ainsi lorsque la pédale est enfoncée la vis entre en contact avec la plaque ce qui ferme le circuit. Pour le retour de la pédale lorsqu'on la lâche, j'utilise simplement des élastiques. Matériel utilisé : * Un jack 3.25 mm * Un adapteur jack 3.25 vers jack 6.35 * Visserie M4 * Quelque élastiques Codes openSCAD des différentes parties :**
