Below,the very skeleton of the VC (only LCD is represented;lacks motherboard,keyboard,batteries,and all the stuff inside the central bloc (see step 3).
Step 1: General Concept and Ideas (e.g.:warning,drafts!!)
This would be the chassis of our VC (Versatile Computer ;) :a general framework to have a common ground,and even with any piece available,the only cleverness needed would be to know enough the framework and the computer in general to make fixing (screwing) and wiring. :)
The total costs would be:
-the material and manufacturing of the framework (plastic or steel or ...?)
-the lcd screen (=>reversing of the connection probably not easy;depends of:standard or mostly proprietary?)
-the electronic interface,the (cheap!) heart of the framework,which glues all the rest together:
-made-up keyboard/mouse<->PS/2 (or COM) motherboard port
-USB key or memory card <-> IDE port
-VGA <-> LCD and perhaps TV (LCD can remain an option:think CHEAP! (and adapted) ;)
-power interface: AT connection <-> (batteries) <-> hand crank charger,solar/water/wind electricity,(place local method of electricity production here)
-optional components:mass storage (USB key,...),batteries,touchpad,(whatever peripheral)...
-The power interface should be VERY robust:if the electricity is locally produced,I doubt there will be a local engineer too to verify the voltage is always at the same (good) level...The first sign will be the components burning. :/
-The framework should integrate the space for future or probable devices: 3 1/2 and 2/13 hard drives,usb key, cd reader/burner,...
-As I think of:PCI adapters to have one (or two) PCI cards horizontally (the more I think,the more I fear it's going to end with a mammothian Altair-like laptop!)
-The LCD should be formated in a plank shape,which would be inserted in the guides of the framework (forming a closing lid).
-The electronic interface,the LCD and the memory storage (HD,CD,usb/flash) (and the hand crank charger?) should form a moving bloc;in fact,the framework is an open box,with the motherboard on its ground;the moving bloc should move along rails,digged into the walls of the box.Having the things that way will allow to adapt to the position of the cpu and its fan ;) on the motherboard;next,we only have to place/inlay/crush the keyboard (and batteries?And hand crank charger?).
-The conditions of work of the hardware won't be what it was conceived for:heat,high hygrometry,and dust.Therefore,the final product will have to be isolated (filtered windows) and well ventilated.
Below is a general scheme of all the parts and their connections.
