cd player din cdrom
« on: February 25, 2009, 12:18:25 PM »
am gasit pe site schema de aici: http://www.electroniq.net/ro/other-projects/90-cd-player.html
nu sunt insa si valorile pentru piesele folosite, si cum nu ma pricep prea mult, mi-ar fi necesare.

inca o chestie, am un mp3 player portabil cu alimentare la 5V; daca as folosi schema de aici: http://www.sminntech.com/images/7805datasheet.gif, ar fi de ajuns pentru a-l pune pe masina?

In prima schema Diodele sunt 1N4007 , C1 si C2 sunt de 1000uF /25V  , condensatoarele C3 si C4 sunt de 470 uF/25V .
Transformatorul trebuie sa fie cu priza mediana si sa aiba urmatoarele tensiuni in secundar :12-6-0-6-12V .
In cazul in care doriti sa conectati un mp3 player puteti utiliza schema de mai jos si sa mai adaugat la iesirea regulatorului un condensator de 470uF .

Regulatoarele de tensiune necesita montarea pe radiatoare adecvate pentru disiparea caldurii .

I think this is a common thing that everyone should know him. I think that everyone should read.
