A friend donated me this old laptop, which had a broken LCD. The laptop was old but it worked just fine. I had no intention to spend money to get it repaired, it just would not worth the money. Instead I just removed the screen from the body of the laptop and used the laptop as a HTPC connected to a TV.
Then the screen part was pretty much useless, I could have just trashed it, but I just kept it, just in case I could do something with it. Then I had this idea that I could turn it into something useful.
It turned out that it is very easy, and very useful if you're into drawing. It is a light board/table for drawing, it is very cheap and portable, you can easily carry on your backpack with your books.
Take the old laptop apart, and separate the screen completely off the body of the computer.
