I was thinking a bit about the whole project, and I made up a plan. At first I\'m going to make the Pi work with as many already available accessories as possible, then gradually switch to custom parts fitting into the small chassis.
My display is a AT070TN92, bog standard 7\" display, and it is a LED backlit WVGA display. There are readymade controller boards for this type of display, but I have yet to find one with a DVI input, they all use VGA, or AV, but if it is possible, I\'d like it to be digital. A \"big\" problem is that all these controller boards seem to be too big for the purpose. However, in this forum, I read about a solution involving a TI TFP410A and an LS75LVDS86 IC that is supposed to work - and that seemed small enough too. (info here: http://www.raspberrypi.org/?page_id=43& ... ic&t=176.2
) But this still seems to be a bit of a shaky road, this is the most difficult part now. If this succeeds however, I think the controller board can be used to control all the same interface screens - which means a lot...
Well, I have to make some more research, but it seems that the keyboard has the raw matrix put out, which means that theven if I can\'t quite find a suitable controller board, I can make one using an Atmel AVR yC for example.
The touchpad might be of interest, that might involve some analog electronics.
In the far future, I\'d also like to apply a touchscreen interface to the screen, but that seems to be an easier thing to do, there seems to be an ample supply of solutions for the job out there.
I checked the battery of the netbook, and it seems to be a simple standard battery, using only 2 leads, and I\'d be surprised if there is no single chip solution that charges it when needed, and uses it, when no other supply is present. Also, I\'d bet there is some kind of interface to it, like I2C or something along those lines, with which, the battery status can be queried. Also, I think that it can be used to cut power to the board (for ACPI like \"turn off\" behaviour). This doesn\'t seem to be an impossibly difficult task.
Board to make connectors line up with the chassis
This is just the topping on the cake, to make the whole thing appear the same as before... The netbook has 3 USB ports, an RJ45, an SD card reader, mic in and audio output connector. I plan on making some mods to the case though, to enable more features.
