LittleBox | The DIY Raspberry Pi All-In-One Desktop PC by Gregory L Holloway The LittleBox is designed to be built at home, by anyone, and with the minimum of tools. Everything you need to turn your Raspberry Pi into a Desktop PC is included as part of the complete LittleBox kit. I am a huge fan of the Raspberry Pi. It has sparked a revolution in the computing world, and has inspired millions, including myself. The LittleBox is the culmination of 18 months of working with the Raspberry Pi. We have a Base-Station which is used to control and monitor our Proof-Of-Concept Vehicle, and I wanted everyone to be able to share in the experience. The 61 Laser-Cut parts are are produced from a single sheet of 3mm Birch plywood. The HDMI cable is hand-made here in the UK. The LittleBox design & prototyping has been documented on Instructables. It covers everything from the LittleBox's inception, development of the two prototypes, electrical testing, and stress testing. The link is Specification.
Tutorial: How to Set Up a Raspberry Pi Web Server People are doing a lot of cool things with the Raspberry Pi. One of the first things I thought to do was to see if I could make a Raspberry Pi web server. Being a web developer and overall geek I figured it might be kind of fun to do, and as I found out it’s really easy. Getting Started Setting up a Web Server on this device really isn’t much different from any other Linux machine, but there are a couple things you’ll want to do in order to get it working right. The first thing you want to do is get the Raspian Wheezy Image from here. The Raspberry Pi has a “memory_split” option that divides the memory between the CPU and GPU (Graphics). You may want to also enable the SSH server if that’s how you’re going to be accessing the device. Note: You can overclock this device, but I wouldn’t recommend it. After you’ve saved your settings reboot the device. Next we’re going to do a firmware upgrade, we need to install git: then download the firmware update and run it: Install Apache and PHP: Summary

How to make a Raspberry Pi Case | Design Modelling with Jude Pullen Step-by-Step Instructions Individual parts broken down into short 1-3min. videos. Some with time-lapse to keep it short – but still show the techniques. (As mentioned – still work in progress, so please send any suggestions to jude_pullen@yahoo.com ). The main objective here is to allow you to clearly follow the process – but – become comfortable enough with these techniques to make it your own. Screenshots A quick overview of the main parts of the tutorial. Sketches Work through a few ideas you might have in rough first. Rough-Mock-Ups Don’t worry about being too accurate – play around with different styles/materials. Basic Template You can also download my original layout here. 90 Degree Joint Technique If you are new to this ‘filleting’ method, using a ruler, click here. I’m Sticking With You… Yup, this part takes a while, but the result is pretty unusual, I think. Simple Window You can always make a simple viewing window, rather than Light Pipes.

Contrôler son bureau à distance avec VNC sur le Raspberry pi Dans cet article nous allons voir comment télécommander son Raspberry pi à distance grâce à VNC (Virtual Network Connection), pour que cela fonctionne il faut que vous ayez suivi le tutoriel sur SSH et donc que vous puissiez vous connecter en SSH à votre Raspberry pi. La différence entre SSH et VNC est que SSH ne gère pas d’interface graphique il ne vous permet que d’exécuter des commandes dans le terminal, contrairement à VNC qui va vous donner la possibilité de contrôler votre Raspberry pi de manière graphique avec la souris et le clavier. Nous allons donc commencer par installer un serveur VNC, il en existe plusieurs, mais celui que je vous propose est tightvnc. Pour l’installer connecter vous en SSH au Raspberry pi et faites ces deux commandes sudo apt-get update sudo apt-get install tightvncserver Une fois que tightvnc est installé il faudra faire la commande vncserver :1 Si vous recevez un message d’avertissement cliquer sur continuer. Le bureau de votre Raspberry pi devrait apparaitre.
Touchscreen on the Raspberry Pi | Mark's space dot com To accept input from a touchscreen we have to use the event interface of the Linux input system. We use the ioctl capabilities of the event interface, in addition to the normal read and write calls to get information from the touchscreen. This blog post explains how to use the touchscreen within your own programs using C as well as writing directly to the framebuffer. Images of my TFT from a previous post; Link to the code; The touch screen I have is a 3.2″ TFT from SainSmart. Linux Input System To accept input from a touchscreen we have to use the event interface of the Linux input system. To view the input devices on your system, use cat /proc/bus/input/devices Below is the output from my Raspberry Pi. The above output shows that the handler for my touchscreen is event0, or “/dev/input/event0″. An example ioctl is shown below, this gets the name of the device using EVIOCGNAME. The above features are listed in linux/input.h as; The Code
Raspberry Pi: Project 1 – Pandora Streamer « Engineering « Shaun Gehring Overview – What is it Using a Raspberry Pi you can create a pretty cool stand alone Pandora Streamer. Its a pretty easy project to put together and will only take an evening. Even though this project is basic from a Electrical Engineering standpoint you will learn the basics of GPIO, Python, BASH and basic Circuts. The best part is you can totally use this project on a daily basis. I do not just want to show you what i did but show you where i went wrong and how i got the correct answers so you will feel confident trying this stuff yourself.

Pitié pour la carte SD de votre framboise314 : Bootez sur un disque dur USB La framboise314 est conçue pour fonctionner avec une carte SD. Pratique, léger et pas cher… Oui mais… comme toujours en informatique, il y a le côté obscur de la force ! La durée de vie des cartes SD est limitée entre 10 000 et 100 000 écritures ! Et votre OS ne travaille QUE sur cette carte. Même si les constructeurs ont intégré des mécanismes de répartition d’écriture pourquoi ne pas booter sur un disque dur externe ? Prérequis Attention, cet article s’applique pour une installation de Raspbian seul sur une carte SD. Premier démarrage Pour commencer, regardons comment démarre notre framboise314. ), l’écran s’illumine, y’a plein de trucs qui s’écrivent et… ouf ça y est le curseur de la souris apparait sur un fond de LXDE ! Le SOC et le démarrage de LINUX La mise sous tension En fait ce qui nous intéresse ici, ce sont les toutes premières secondes de ce démarrage. A la mise sous tension, seul le GPU est activé. Sur cette première partition de la carte SD (mmcblk0p1) on trouve : /! !
Engineering(DIY): Adding 7inch display with touchscreen to Raspberry PI Hi! First thing I got in mind when seeing Raspberry PI was "car PC project". The targeted display was 7 inch with touchscreen. I have found a lot of displays on Ebay. I have got myself one for 85 dollars with free shipping(this; if it is not available any more you can search "reversing driver board hdmi" on ebay and you will find others). It took less than a month to receive it(in Romania). I have installed latest Raspbian image on a SD_Card and tried it on my Raspberry PI model B, but the touchpanel didn't show any input. First thing, I have run lsusb to see the touch controller type(on RaspberryPI): pi@raspberrypi ~ $ lsusbBus 001 Device 002: ID 0424:9512 Standard Microsystems Corp. Last device is the touch controller, from eGalax. Edit: If you don't want to build the kernel by yourself, you can download mine from here.

Coffee Table Pi The LCD screen I went with a 24inch LCD screen with LED backlight. Select any size screen you wish. Make sure it has good viewing angles as the screen will be mounted upwards and almost always viewed at an angle. Select one that can be wall mounted as it can then be attached to the table from underneath. Select one that turns on without needing any buttons to be pressed as all the buttons with be hidden inside the table. The Joystick and Button This is up to you, I went with a Happ 4 or 8 way arcade ball top joystick, 2 blue American style buttons, 1 player and 2 player buttons. Perspex sheet 4mm Cut to the size of the outside edge of the LCD screen, larger than the viewing size of the screen as it will be screwed onto the underside of the top of the table. Wood, glue, screws, stain and finish This is all up to what you want to do. Sound I recycled a nice 5inch speaker for the sound and used the circuit from an old set of computer speakers.
