Hi all , i'm pretty new on this site.
I've got a new project, and i need (probably a lot) of help.
I want to reuse an old ps vita or psp to insert a raspberry on her.
These cases are pratical with buttons and joystick already include, and some elctronical stuff that i will be able to reuse like battery
I had this idea a long time ago, but with the new raspberry pi zero, that give me up.
I will prefer the vita for some reasons. This one have a lot of advantages for me :
- smart case (already have audio output, some access behind cache, can hide some hdmi or use connector)
- good screen ( 5"), or at least, enough space for a 5" screen
- bigger that a psp, so easier to fit in.
The aim of this idea is to have a really small computer inside a pocket. Well, with the vita size, i can say my bag. Also to be able to use it like a game console, like a computer (with external screen & keyboard), or like a remote for domotic projects.
What i already know :
The screen probably can't be reuse, so i was thinking about something like this : http://eud.dx.com/product/5-inch-hdmi-t ... uG36-bh2PU
I will have to use a dremel and other stuff like that to be able to put a raspberry (even a zero) inside a vita case, but as long that it has a good prehention, i don't care.
The most harder thing that i know i will not be able to deal with is the use of button pcb of vita.
I have seen some stuff in this link viewtopic.php?t=110844&p=764609 or this one : http://xim4.com/community/index.php?topic=31390.0
One of my possibility is to cut the pcb and solder io with raspberry or a temp pcb. I think that i'm not able to solder on so small things.
I've already look "inside" a vita by this link https://fr.ifixit.com/Teardown/PlayStat ... rdown/7872 and i have the feeling that all buttons infos use the two connects cables (step12 from ifixit).
So i look for a way to reuse this cables and connect it with the psvita. I don't know what could be the better options.
And it's here that you can give me some help.
I was thinking about use something like that http://www.davtech.fr/cables-nappes-car ... attes.html or that http://www.ebay.com/itm/311077593105. But in fact, i would prefer a version with connector directly solder to it (if you know where i can find it ... I don't even know the name of the type of connector in need).
After that, a think it could be possible to use the io of these cables with the pi. For the moment, i will prefer try to use it directly on io, but an other possibility (tell me if i'm wrong), could be to use a converter. On the pictures, i counted 10 io by cable, so pottentially 20 io (some should probably be redundante no ? ).
Where do you think i could find a schema of the io to know what pass inside the cable and at which position ?
What do you think about this project ?
Do you know some similar projects ?
Can you give me some advices or clue for this.
Thanks a lot for your help.
