I have one old Toshiba Satelite laptop here sitting on my desk. The Mother Board is dead since ages but I kept it for unknown reasons.
Finlay it came the day to reuse some parts of it and I managed to reuse the display. Now the display is used along with one ODROID-C1 and it works perfectly!
Now I am planing to turn the ODROID and the display into a hipster laptop made of wood attaching small keyboard with touch pad (those from logitech)
For that I want to reuse the laptop battery and make a device which recharges it once the power is plugged in. (as you would do normally with a laptop)
I am fairly stupid on such things and I need your help. I have 3 arduino Uno boards. All I want is to have the battery charged and to use it for powering the ODROID and the display.
I don't need to monitor the battery charge with arduino monitor. I can do it trough the serial and USB. I found one guide here: http://linuxehacking.blogspot.com/2014/03/recharging-and-reusing-acer-laptop.html but it includes too much things, that I won't need (the bigger arduino board and the monitor).
How can I shrink it to the use of one UNO? I also have 12v to 5 v converter which I am currently using for powering the display and the ODROID. It will be preferable if I can still do that with the additional battery "device"
