This is a story is about a boy who is 15 years old, And he wanted to build something he would really like to have. So he started building took some old stuff from his parents en builded his first prototype. It's awesome he tough!! But then he realized it should have a nice case and he took out what he builded and made a really dumb mistake and the display died...
so he needed another display so he ordered one and it arrived. It was a nice 3.5" screen and it used composite video. He builded his second prototype but his raspberry pi broke. not again he tough and he gave up. But then a few weeks later he got a new raspberry pi for his birthday, yeah!! He started building the final prototype his third one and it is even more awesome. It has a raspberry pi b+ in it and also has a arduino that is used as a second option to display stuff and to work with the buttons.
Hopefully I won't destroy this one but I learned a lot with this project, And also I destroyed a lot.
but it was worth it.
To make it portable it should be small end use less power. I use a 16x2 character display.
It does not matter which computer you take, but in this project I am using a Raspberry pi B.
just wood not to thick

Today I putted the whole thing together.
- The main 3.5'' display .
- This are the button to control the computer. It is made a bit like the neotype(http://hackaday.io/project/1386-neotype-haptic-computing) project of Paul Beaudet..
- This is a arduino pro mini placed to control the buttons.
- this is the power part for the rpi it uses 4 aa bateries and a buck converter to convert it to 5v.
- The rpi b+ it self it is screwed down with 4 2m screws. The best fiting screws are 2.5m but in the shop were I buy all my screws they told they were pretty rare.

EDIT: I ordered the screen now waiting :)
A few day ago I started rebuilding this projects to make it more portable I made it smaller and I want to use a new screen that is smaller(3.5") and uses less energy(http://www.adafruit.com/products/913). I have almost enough money to buy the screen after that I will make a new update. at the moment I can power it with 4aa batteries maybe I will find an alternative. I am sill thinking about how should mount the screen like a laptop screen or like a gameboy(flat) or maybe somehow else what do you guys think?
This is how it looks now:
This is the booster I havet to power the display as soon as I have it:
