A homemade LCD tablet screen my brother made for me to fiddle around on. My Bamboo Pen tablet is on the bottom, with a laptop LCD screen without the metal in the middle and a sheet of glass on top to protect the LCD. I was only able to draw on the parts of the LCD that was directly on top of the tablet censor. The size was about 3x6 inches in the middle. You can build a full size one by getting a bigger tablet. This was only a test, but was still very cool! :)
If we decide to experiment with homemade tablet screens again, i'll be sure to make a "How to:" for you guys!
