Hai salut! Revin in electronica dupa o vara intreaga de leneveala si fara nici un circuit, si as vrea sa-mi mai aduc aminte cate ceva, ca am uitat tot. Ma gandeam sa-mi construiesc, pentru distractia noastra la scoala, un 'interfon', sa comunicam mai bine in galagia de acolo. Doua microfoane, doua seturi de casti... Pot face 2 preamplificatoare pentru microfoane care sa scoata un semnal destul de puternic pentru casti? Stiu ca e problema cu impedantele... Dar am uitat cam tot.As vrea si eu o schema (nu foarte complicata, va rog, ca mi-e cam somn :smt003 ), pe care s-o dublez, sa-i pun 4 mufe, o baterie, o carcasa si s-o iau maine la scoala. :prayer:
