hello guys im new to the forum i am working on a project solar usb charger i know that there have been simular post before . i have drawn up a very simple schematic i haven't wired anything yet. if someone could check it for me just to make sure i have no problems thanks Brian
i have a few worries about my current schematic draft
1 that the switches are wired correctly and that it is possible to get solar and voltage readings
2 i wanted a way indicate that the solar cell was getting power so i am looking at getting a 9v pre wired led so i dont have to use resistors but if the solar cell is 9v and the led the same 9v will any power go to the rest of the circuit?
i know i could use a regulator and resistors..but what would be the best way to go about having an indicator that the led is getting power
i am using
a car charger usb with 34063ap1 chip.. so the voltage will be relegated correctly (i think)?
9V 3W Mini Solar Panel (cell)
led indicator
2 1N914 Schottky Diode
9V Volt 300mAh Ni-MH Rechargeable Recharge Battery
2 switches
voltage meter

i will attach schematic below
thnaks again Brian
