Sursa atx-curent si tensiune variabila

Recommended Posts

Guest Silviu Cocoloș

Intentionez sa modific o sursa ATX ce o am de la vechiul calculator.M-am inspirat de la un video de pe youtube.O sa folosesc 4 binding posts,unul va fi ground,unul +3.3V,unul +5V,si unul +12V.O sa mai trag un fir care scoate +12V si un ground,pe care o sa le leg la un modul step up step down converter,dupa o sa aplic inca 2 binding posts separate de cele 4.Am sa folosesc un display de tip multimetru ( cu ampermetru si voltmetru) ,am sa modific putin modulul in sensul ca am sa folosesc potentiometre clasice (de 200k si 500k) pe care am sa le aplic pe carcasa langa binding post-uri.De asemenea un comutator (firul verde plus cel negru) ca sa pornesc sursa,precum si un led cu rezistor care indica starea.Pareri?
