Just another crazy idea from your friendly mad scentist 
If you have around a broken LCD panel, from a notebook, or also better, from a monitor, and you need a luminous plane for draws tracking, you can build it yourself very easy.
The idea started when my little cousins asked me for a draw tracking panel for track al the images they have to do for school researches ..... looked around, but here is not a common article, and professional ones have a price that is simply absurd, for give them to little kids.
But i had some old broken 15" LCD panels around in the shop, to throw away, that i kept for take away the polarization film (for an experiment i had in mind), and they still had the lamps good, so i thought, "what the hell, why not ?", and dismantled them ..... then took a piece of plexiglass larger than the panel, glued the back part of the dismantled panel on it, with a second layer of plexiglass under it (Glass was better, but no glass, they go in the hands of kids, and cannot expect that little kids may be too much delicate), and closed between the plexiglass layers the panel with the diffuser and the lamp, and also the switching elevator (safety, safety), making in a corner just the space for a power connector (the plates are powered with an external 12V power supply), and using strips of plexiglass for make the borders and keep the two panels at the right distance.
So, now both them have their own DIY "futuristic-look" (circuit and wires and the rest seen in transparency don't look bad, if the mount is made well) tracking plates, are happy to show them to the friends (also if is not good to say, unique pieces always cause a bit of envy), and i recycled parts that, otherwise, i had to throw away.
By the way, this also gave me another crazy idea, but i'm still building this last one ..... the third one, she become 7 in a pair of weeks ..... she always want a light in the bedroom (she's scared from darkness) ..... and she's also a good drawer at school (for her age, she have more proportion sense than me, at 47 ) ..... so i thought, if i take another broken panel i have here, dismantle it, insert the backplane and lamp inside a fancy paint border (how do you call them ? ..... picture frame for wall mount ?) with a large border, putting in the border all the electronics, a little circuit with a hidden photocell for turn it on and off at night and regulate the luminosity, and a front plexiglass transparent plate that can be opened and closed easily .... so she can put her draws into it, and also use them as night light ..... suppose that can be a good gift, as a birthday present
What do you think, am i crazy enough, or do i need more practice ? :crackup:

..... times ago, using a good LCD glass panel, and a backlight projector (or whatever you call them ..... are these old units for project on a wall the draws that you made on transparents).
