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 ?
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 !
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?
Use a Mini TV Instead

1) take the batteries away , beside the solar panel.
2) connecting the RCA cable.
but how?

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)

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+

take the huge monitor away !
and take the huge Notebook away !
i remove the BASIC from nano for gainning memory
and use TVout library !

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 !!

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 !!
