Active Solar Panel(tiny PC_part 2)

1) easy.

2) simple.

3) homemade.

4) portable.

5) without battery.

In outer space.
both space-station and satellite things will not carry anything that no need.

i am wondering about that how to disconnect the usb cable

from notebook and run it standalone out.

as if shall i attached the standalone computer under my solar panel,
therefore i should disconnect the batteries and disconnect the USB cable then,

but still send the voltage value back ! but how ?

Step 1: Old PCs

The monitor in 1970 mostly like 50 x 50 x 70 cm,

and the Apple ][ is mostly like 10 x 50 x 85 cm.

so, i gotta shrink it into 0.5 x 2.5 x 4.2 cm.

ie, i could use that arduino which just is "nano" then !

Step 2: How to Make It Stand Alone?

how to run it without USB cable?

means : how to make the arduino_tiny PC portable?

ie, how to make the arduino_tiny PC standalone without battery and monitor?

Step 3: Use a Mini TV Instead

1) take the batteries away , beside the solar panel.

2) connecting the RCA cable.

but how?

Step 4: Materials

1) arduino nano x 1(for every panel)

2) RCA cable x 1(for every panel)

3) mini monitor x 1

4) solar panel x 1

5) 1K Ohm x 1

6) 470 Ohm x 1

7) 2.2K Ohm x 3(for every panel)

Step 5: Circuits

but how to connect pin(s) to RCA to TV?

pretty easy :

1) CONNECT PIN9 == 1K == RCA

2) CONNECT PIN7 == 470 == RCA

3) CONNECT A WIRE GND ==== RCA_GND

4) CONNECT A1 A WIRE ==== TO SOLAR PANEL(2.2K)

5) CONNECT A WIRE GND ==== TO SOLAR PANEL GND

6) CONNECT A WIRE VIN ==== TO SOLAR PANEL V+

Step 6: Test Run

take the huge monitor away !

and take the huge Notebook away !

i remove the BASIC from nano for gainning memory

and use TVout library !

Step 7: Finished and Further

Setup a patch panel inside the space-station,
in order to shoot solar panel to usable at once.

if show up the power good then connect- it !

PHOTO : i try to connect 12V solar panel indoor.

but 12V fry the nano , so that i use 2.2K * 3 to devide by 3 !

made the every solar panels are active and smart !!

Step 8: Code

Here is the code in C.

coz i remove the BASIC already.

for remove the Notebook in deed,

and i include the tvout lib !

HAVE FUN !!
