Chci se zeptat ohledne napajeni hracek jako v pripade teplomeru po ethernetovem kabelu. Mam tu pekny 31V (3A) spinany zdroj ze starsi HP tiskarny. Teplomer by mel v sobe napr. DC-DC menic MC34063. Rad bych, aby mel DC-DC menic i nejakou ochranu proti prepeti (kdyby hlavni zdroj odesel aby to neodneslo vsechno co by na nem bylo povesene).
