Guest vladuz Posted January 15, 2005 Share Posted January 15, 2005 Vreau sa alimentez un aparat la 3V de la portul USB sau serial. Imi trebuie neaparat 3V, 2.9 minim 3.0 maxim, ~290mA. Sa zicem ca asta s-ar putea face, dar cum fac un switch on/off din software?Deci, un rezultat final ar fi genul: o comanda, alimentarea e on, o comanda, se stinge alimentarea. E posibil, si daca da, cat mai multe detalii va rog.M-am gandit: alimentare cu un zenner de 3V de la molex(sursa), si control din pararel si serial? Dar.. cum? Multumesc. Link to comment
Guest vladuz Posted January 15, 2005 Share Posted January 15, 2005 http://www.electrokits.com/electronic-k ... ers/43.htm Asa ceva cred ca este ce vreau eu, ma rog, nu asa de complex dar ceva foarte asemanator. Uitati si un PDF cu o schema, e usor de facut? http://electronickits.com/kit/complete/elec/ck1601.pdf Link to comment
