Default Cutiuta muzicala electronica

Salut,
doresc sa multumesc tuturor celor care fac posibila existenta acestui site, am invatat foarte multe lucruri citind articolele si postarile de pe forum.

Revenind la subiectul acestui thread:

As dori sa achizitionez o cutiuta muzicala care, in momentul deschiderii ei , sa poata reda o portiune dintr-o melodie ( maxim 20-30 sec. ). Probelma e ca as vrea ca eu sa pot pune/incarca portiunea de melodie in respectiva cutiuta.
Am tot cautat pe internet asa ceva dar nu am gasit decat cutii muzicale mecanice .
Asadar , poate cineva sa ma indrume catre un site sau sa ma ajute sa "construiesc" o asemenea cutiuta ?
Pentru ca nu am gasit pe internet sau in magazinele din oras ( Brasov ) asa ceva, ma gandisem sa folosesc o cutiuta pentru inel si sa pun in interiorul ei ,electronica de la un mp3 player zen stone plus pe care il detin. Iar aici intervine a doua problema : nu ma pricep la electonica si nu stiu cum sa conectez butonul play de la player cu deschiderea cutiutei.

Sper ca se intelege ce am scris mai sus.

Multumesc!

Asa ma gandeam si eu...

Nu-i niciun electronist din Brasov activ pe forum sa ma ajute cu problema de mai sus ( contra cost bineinteles ) ??

Este vorba de o portiune dintr-un mp3 sau tot mp3-ul .

Atunci ai nevoie de de o memorie pentru piesa, de un decodor audio si de un mic microcontroller. microcontrolleru iti trimite piesa de la memorie la decodor. S-ar mai putea pune un amplificator mic, depinde insa de ce ai nevoie.

@ hellfish

M-ai bagat in biblioteca .

In lipsa cuiva care are poate face asa ceva, as ramane la ideea mea de mai sus legata de mp3 player. Player-ul are incorporat si un difuzor, asadar as putea sa-l las fara carcasa si sa montez doar partea electronica a lui intr-o cutiuta obisnuita pentru inel .Dar , cum am spus mai sus , nu stiu cum sa conectez PCB-ul player-ului la un intrerupator .

Multumesc.

L.E. fizic mp3 player-ul are un buton pentru play. Nu stiu cum arata electronica lui pentru ca nu vreau sa-l desfac decat daca gasesc pe cineva sa ma ajute.

Daca e cu buton atunci ai putea folosii ceva ce iti da un impuls ca sa-ti porneasca cantarea, daca e cu touch e mai naspa.
