problem part 2

 because current too low to charge the cell phone, this circuit need more current because current from the solar panel too low.

how to solve?

need to change the solar panel? using  a bigger solar panel with high power?

need to buy another solar panel to make it more current? series it?

new battery

rechargeable battery. 6V. 1500mAh. Ni-MH.

all specification is what i really want for my project. but this battery too difficult to find and too expensive compared to other because it is rare.

problem

first, i'm using battery non-rechargeable to test the circuit. then, i change into rechargeable battery. when going to buy the battery, the 6v was to difficult until one shop have it. but it not Ni-MH but Ni -cd.

because of i'm want to charge to become high voltage after using it. using the solar is to slow. then, i want make it faster by using the charger of 6v. but it is not suitable and make it broken and burn it.

after charging:

p/s: i need to find another rechargeable battery. it is must be Ni-MH battery 6V because the Ni-cd too low their current.

circuit

full circuit

charging controller:
if solar panel  have the voltage, the LED will light ON. then, the current will flow to recharge the rechargeable battery or charge the cell phone.

voltage sensor:
connected from charging controller to pic circuit

pic controller & relay:
as the controller and LCD will display  the voltage in the back up battery .

make a PCB circuit board

1. The first part, we have to print the circuit diagram at the iron on PCB paper.
2. Cut the paper following the paper with the size needed of our PCB board.
3. Ironing the printed iron on PCB to the PCB board until the ink stick to the PCB board.
4. After the circuits have stick at the board, drill the entire hole that needed for all the components
5. After that, we have pour an acid to make the circuit can be used
6. Clean the board with the thinner.
7. Solder all the components at the PCB board to complete the process

design pcb using software

after design circuit at protues, then it need to design the pcb. there show one of the circuit.
