The end of the project shows you what you can do with a more recent laptop with a real graphic OS. I am curently working in improving the interface on this laptop.
This is a nice way to recycle old hardware you can found or buy for cheap.
Step 1: Find the laptop
Remove the screen. I recommend you to keep the plastic enclosure and cut the edge so that you can glue the back and the laptop with the back of the screen without damaging the LCD.
So find a way to reverse the LCD by cutting the screen hinge.
