前幾天半夜1點多在北宜公路上迷路,
靠著僅剩1%電力的手機 GPS定位+離線地圖 才平安回到家,
這個驚險的經驗,讓我想在車上加裝USB供電。
上網看機車USB供電套件一個600多元,
因為我是本科系學生,
做過一些電子電路和MCU自控應用,
知道主要的電路零件其實不到50元,不願花600多元只買美美的塑膠殼,
但還有是有些地方輸車行:
1.鑽孔等外觀沒辦法弄得美美
2.對機車電系不夠了解
目前想來自己土炮機車USB供電,
完全從頭搞的話,就要自己焊7805與USB接頭,
不過太麻煩了,我應該會買車用的12V to 5V來做
因為怕雨水和其他外力破壞,目前打算先裝在坐墊下,
克服雨水問題的話就可以裝在龍頭附近
目前只要解決以下這兩個問題,我應該可以土炮出一組不美觀但實用的USB機車電源
a.請問SV-MAX坐墊附近有來自電池的12V電線嗎?
b.發電機經過整流後的最大值是多少呢?
