VU-metru cu VFD

Recommended Posts

Am pe acasa un VU metru VFD si as dori sa-l folosesc . Singura problema e ca nu stiu cum si cu ce sa comand display-ul, ca sa functioneze ca un VU-metru. Am pus si o poza cu el (scuzati calitatea dar altceva nu am avut)Aveti niste idei?????

Identificati terminalele filamentului, alimentati la 3-4v dc pana se vede filamentul rosu-visiniu (filamentul este format din niste fire subtiri, 3...4 la numar conectate la capete in stanga-dreapta afisajului.Identificati anodul unde trebuie aplicata tensiunea inalta (minim 15V). Prin conectarea la masa pe rand a terminalelor segmentelor acestea se vor aprinde.

Ala e balonul de la casetofonul deck Iauza 221, filamentul e la 6,3Vca si se poate comanda cu integratul de la Kastan, mai putin digitii de contor. Daca pui un plastic fumuriu peste el nu se va vedea decit partea de vu-metru.
