Summary

Update 08/09/17 : new raspberry Pi2 embox : https://www.thingiverse.com/thing:2514014

Le Raspberry Pi est un ordinateur miniature permettant la réalisation de nombreux projets, disponible dans le commerce dans sa forme la plus dépouillée, il se prête à l'intégration dans tout type de boitiers. Ainsi, l'objectif de ce projet, consiste à réaliser un nano ordinateur de la gamme UMPC (Ultra-Mobile PC) intégrant différents composants du commerce.
Il s'agit là d'un exercice d'intégration de composants du commerce permettant un exercice poussé de conception de boitier technique.
Attention : les modifications proposées peuvent être fatales à votre matériel. Ce projet est proposé "tel quel" sans aucune garantie de succès dans la réalisation et dans son fonctionnement.

Raspberry Pi is a miniature computer allowing the realization of numerous projects, available in several shops in its barest shape, it lends itself to the integration in every type of cases. So, the objective of this project, consists in realizing a nano computer of the range UMPC (Ultra-mobile PC) integrating various components.
This is an exercise of integration of components allowing an advanced exercise of conception of technical case.
Warnings : The proposed modifications can be fatal in your equipment. This project is proposed "as is" without any guarantee of success in the realization and functioning.

Pour réaliser ce projet, il faudra les composants suivants :
To realize this project, it will be necessary the following components:

Préparation du Raspberry :
A faire avant toute modification du Raspberry : Préparer la carte SD du Raspberry en suivant les instructions proposées par Adafruit pour l'utilisation de la platine Kippah. Pairer le clavier bluetooth, paramétrer la connexion WIFI. Vérifier que tout fonctionne.

(Attention, cette intervention annule la garantie et peut détruire le Raspberry en cas d'erreurs)
Afin d'intégrer le Raspberry dans le boitier, il est nécessaire de le dépouiller de pratiquement tous les connecteurs dont il est pourvu. Pour ce faire, il est possible de suivre les conseils proposés par Adafruit : https://learn.adafruit.com/diet-raspberry-pi/steps.

Preparation of Raspberry:
To make before any modification of Raspberry : Prepare the SD card of Raspberry by following the instructions proposed by Adafruit for the use of the deck Kippah. Paired the bluetooth keyboard, parametrize the WIFI connection. Verify that everything works.

( Watch out, this intervention cancels the guarantee and can destroy Raspberry in case of errors)
To integrate Raspberry into the case, it is necessary to deprive it of practically all the connectors with which it is provided. To do it, it is possible to follow the advice proposed by Adafruit: https: // learn.adafruit.com/diet-raspberry-pi/st eps.

Il est ensuite nécessaire de raccourcir les pattes du port GPIO de façon à ce que, lors du montage de la platine Adafruit Kippah, l'ensemble ne dépasse pas 8,5 mm d'épaisseur. Il faut également rajouter deux port USB A en remplacement des modèles doubles présent d'origine.
Il est préférable de rajouter un radiateur sur les processeurs de la carte pour un meilleur refroidissement.

It is then necessary to shorten the legs of the port GPIO so that, during the assembly of the deck Adafruit Kippah, the set does not exceed 8,5 mm of thickness. It is also necessary to add two USB port A instead of the double models present of origin.
It's better to add a radiator on the processors of the card for a better cooling.

Clavier :
(Attention, cette intervention annule la garantie)
Démonter le clavier, dessouder la batterie (Attention danger de court circuit) de façon à dégager la platine électronique. Récupérer la platine, la membrane en caoutchouc et le cache. Voir photos.
Câbler la platine pour l'alimentation en 3,7 volts pris de la platine Adafruit Kippah. L'installer dans la partie imprimée puis sceller en faisant fondre les picots en plastiques. Placer la membrane puis le cache en force.

Keyboard:
( Watch out, this intervention cancels the guarantee)
Tear down the keyboard, unsolder the battery (Warning danger of short circuit) so as to release the electronic deck. Get back the deck, the rubber membrane and the mask. See photos.
Cable the deck for the supply in 3,7 volts taken by the deck Adafruit Kippah. Install it in the printed part then seal by melting teeth in plastics. Place the membrane then the mask in force.

Ecran :
Installer le connecteur et plier le ruban ainsi que le montre la photo. Coller l'écran dans le cadre imprimé avec de la colle contact en laissant dépasser le ruban de 3 cm.

Screen:
Install the connector and fold the ribbon as well as shows on photo. Stick the screen in the printed frame with some contact glue by letting exceed 3 cm the ribbon.

Batterie :
(Attention : respecter les précautions d'usage et manipulation des batteries Li-Ion qui peuvent prendre feu et exploser en cas de mauvaise manipulations)
Installer le power booster Adafruit et un interrupteur sur le couvercle de la batterie. Câbler l'ensemble selon le mode d'emploi proposé par Adafruit pour son module.

Battery:
( Warning : respect usual precautions and manipulation of batteries Li-Ion which can catch fire and explode in case of bad manipulations)
Install the power booster Adafruit and a switch on the lid of the battery. Cable the set according to the instructions proposed by Adafruit for his module.

Boitier :
Installer la batterie sur le boitier, passer les fils d'alimentation par le passe câble. Souder les fils d'alimentation batterie sur les pad 5V et GND du Raspberry.
Souder l'alimentation du clavier sur les pad d'alimentation proposés par la platine Adafruit : GND et 3,3v.
Monter la platine Adafruit sur le Raspberry. Installer la carte sd, connecter l'écran et Installer l'ensemble dans le logement prévu.
Installer le support de l'écran LCD : le pivot de la charnière est composé d'un filament plastique à imprimer. Installer le support de clavier en force.

Tout doit fonctionner lors de la première mise sous tension.

Pour ceux qui ne dispose pas d'une imprimante 3D, les pièces plastique composant ce kit peuvent être commandées sur Shapeways.

Case:
Install the battery box on the case, cross the wire of power supply by crosse cable. Weld the wires of battery on pad 5V and GND of Raspberry.
Weld the power supply of the keyboard on the pad of supply proposed by the deck Adafruit : GND and 3,3v.
Install the deck Adafruit on Raspberry. Install the SD card, connect the screen and Install the set in the planned housing.
Install the LCD screen: the pivot of the hinge consists of a plastic filament to be printed. Install the support of keyboard in force.

Everything has to work during the switched on.

would you mind sharing the fusion files? or whatever program you are using :)

working on another project but with the same keyboard

Hi Pokelia,

Thanks for your interest for this project. Unfortunatly, it is not foreseen other sharing except for the STL files.

Best regards and goog luck for your project.

Which kind battery charger do you have use?

Hi Junnu78,

The battery is charged with the Adafruit Booster 1000c module.

Regards.

I mean do you use phone charger?

Hi,

Yes it could be a phone charger as long as you follow the Adafruit specifications.

Regards.

Hi.
Nice projects.
Where you bought on off switch? I don't find it anywhere.
Can you put link here?

Hi Junny78,

Unfortunatly, I found this switch in my components stock and I dont remember where they where bought !
Maybe at Mouser.com it is possible to find it ? You can find on photos the exact size of it.

Best regards.

Splendide conception, ça donne envie d'en faire un même si aucune utilité (déjà bien équipé avec ma GPD Win).
Est-ce que quelque chose est censé se trouver sur la droite de la Pi dans le boîtier principal? Il semble que non, auquel cas on pourrait y mettre 2 batteries 14650 en parallèle à condition d'augmenter l'épasiseur de 4mm et du coup éviter l'appendice à l'arrière...

Bonjour Kilrah,

Merci pour vos encouragements.
Effectivement l'espace que vous mentionnez est, pour l'instant, inoccupé. L'option que vous proposez a été étudiée mais l'épaisseur obtenue n'étant pas satisfaisante, elle n'a pas été retenue. De plus, l'espace nécessaire au booster d'Adafruit posait problème.
Enfin, l'appendice en question offre une autonomie de plus de 4 heures avec les dongles WIFI et Bluetooth ce qui se révèle satisfaisant, il est d'ailleurs certainement possible d'obtenir une autonomie supérieure en choisissant une batterie de plus forte capacité.

Bien cordialement.

Hi DanielBull,

Thanks a lot for your kind comment.
This battery comes from the first ebayer found for a low cost 26650. If you know some other interesting brand, please share.

Regards.

Fantastic project!
I would recommend a different battery though, UltraFire are well known for being very poor quality batteries and lie about the capacity. If you changed to a good quality brand you would probably get between 4 and 8 times the battery life.

Oh, wow, really nice!

I would buy this thing. With an Trackball and Windows and this thing is perfect.

Hi KallenG,

Check the picture : added exact size of the switch. No references to give you because it is comming from my stock.
About Adafruit Raspberry Pi modifications, check the text thing details, you can find the link in it.

What do you mean by "and could you post the raspberry pie please because i can't find it?"

Regards.

and con you post the micro switch you use please

sorry for all of the questions i just want to get the right stuff so i don't blow 150 bucks. lol

Hi KallenG,

Thanks for your interest.
A making of video is not planned for lack of time. But, if you follow instructions from Adafruit for their module, it could be a huge help.

Regards.

ok thanks is there any chance you can give me the link please

and could you post the raspberry pie please because i can't find it?

Thank you KallenG

if you mean the version number, he used a pi B v.1.1, you can see it at the top of the board near the GPIO pins in one of the pictures. I think you might be able to use a pi 3, but i'm not sure on the size difference.

Hi Radon37,

Thanks for your insight : thats right.
Working actually on a pi 3 version : same size, works well but too much heat. I'll update project when problem solved.

Regards.

and could you make a vid of you making it too please thanks!
