About

Interesujesz się elektroniką albo programowaniem? Dobrze trafiłeś! Znajdziesz tutaj zarówno proste projekty analogówki typu zasilacz regulowany, jak i bardziej skomplikowane projekty cyfrówki takie jak karta graficzna. Nie zabraknie tu też czystego programowania oraz porad serwisowych! Disclaimer: Układy pokazywane na niektórych filmach pracują przy napięciach niebezpiecznych dla zdrowia i życia! Pamiętaj, żeby w takim przypadku zachować szczególną ostrożność. Nie ponoszę odpowiedzialności za ewentualne uszczerbki na zdrowiu.

Video Description

W tym odcinku zajmujemy się naprawą zasilacza regulowanego Votlcraft VSP 2405 o łącznej mocy 400W. Wstępne uruchomienie zasilacza okazało się dość efektowne, i zaraz po nim musieliśmy przejść do usuwania pierwszej usterki. A na czym dokładnie polegała usterka i czy było ich więcej, dowiecie się, oglądając odcinek!
