How to build a touchscreen from monitor with broken back-light.
One of my 20 inch monitor’s back-light broke, so I took it apart to build a touchscreen with a wiimote (wii remote) and some normal 12W LED lights. It’s like a little coffee table with a touch screen monitor as a surface.

To see where this whole video is leading to, just go all the way to the last five minutes or so.
In the video I referred to a 22 inch monitor which is wrong. Sorry about that. It’s one of the older 20 inch monitor models from Chimei and the actual size is 16 to 12 inch which makes a 20 inch in diagonal. They appear to be bigger cause of their hight.

The actual measurements for my little interactive “coffee table” are
Hight 30 inch or 75 cm
With 21.5 inch or 54cm
Length 21.5 inch or 54cm
The size of the screen demands the hight. For the wiimote to work you’ll need a certain distance.
The back-light is produced by two 12W LED 110V light-bulbs.
The inside of the box is painted all in white.
For the Ubuntu version, you can use Python-whiteboard for calibrating the wii-remote.
For windows, there are several free and commercial options.

So, don’t throw away your broken monitor!
