Ouverture du planet dédié au Raspberry Pi Cet article a été publié par Benjamin le 29-03-13 à 15:30 dans la catégorie Raspberry Pi Tags : - Libre - Raspberry Pi Ayant reçu un Raspberry Pi il y a quelques semaines, je n'avais qu'une idée de projet en tête : diffuser en ligne la vidéo d'une webcam afin de surveiller mon bébé pendant son sommeil. Puis, en surfant sur différents sites, je me suis rendu compte que des tonnes d'articles concernant le Raspberry Pi existaient. Malheureusement, il n'y avait aucun recensement de ces sites (ou des articles) à un endroit unique. Utilisant les flux RSS à foison, l'idée à donc germée : mettre en place un planet dédié au Raspberry Pi. C'est désormais chose faite. Qu'est ce qu'un planet ? Je pense que la plupart d'entre vous savent déjà ce qu'est un planet. Selon Wikipédia : Pour ceux qui, comme moi, utilisent les flux RSS au maximum, cela devient vite fastidieux de suivre xx sites (et donc d'ajouter xx feeds à son lecteur RSS). Pour ma part, je suis fan des planets. Aucun planet Raspberry Pi...
Pi Accessories How to Customize XBMC 12 Frodo with All the Bells and Whistles Kodi (formerly known as XBMC) is a great entertainment center software. But, here’s the deal: Like many other open source projects, it is driven by a very technical community, and it is not necessarily user-friendly enough for the average person to use and customize. Fortunately, with a bit of time and the right skin, you can set things up properly and make Kodi (XBMC) very user-friendly and rock solid. I have spent countless hours crawling forums and websites, trying to get the live TV setup, premium online content, automatic light control, and all the other settings right. Note: These step-by-step instructions have been tested with Kodi v15, but they should also be compatible with v16 (codename Jarvis). In this extensive and updated guide, I will walk you through the relevant customization tips and tricks needed to take your Kodi installation to the next level.

Planet RaspFR Picade UPDATE: We're now making the Picade work with other systems (esp. Mini-ITX) and turning the controls into a USB HID device. UPDATE #2: We're bundling games with the Picade starting with retro classic from Sheffield's Gremlin Graphics. Don't know what to do with your Raspberry Pi®? The Picade and Picade Mini are high-quality desk top arcade cabinets for your Raspberry Pi®, Mini-ITX, Pandaboard, or other mini PC. The Picade and Picade Mini come in kit form for you to build at home. The only tools you'll need are a screwdriver and a pair of pliers. You then load up your mini computer with whatever games or emulators you want to play, hook it up to the Picade and have a blast! What you'll receive in the Picade kit: Right now we're at the prototype stage. Currently the cabinet panels are laser cut (what else would you expect from the Pibow guys?!) Finally to make it look really awesome we want to commission some custom artwork for decals that you can apply to your Picade. ACHIEVEMENT UNLOCKED!

Presents Wolfson Audio Card for Raspb Overview Wolfson and element14 introduce an audio card to offer Raspberry Pi users the ability to capture audio alongside their camera, and experiment with stereo digital capture and playback. Raspberry Pi, whilst doing a fantastic job of being a small and powerful computer, does this by a number of compromises. One of those is the limitations on its audio capabilities. Out of the box, Raspberry Pi provides good quality audio across the HDMI link, lower quality stereo audio by way of its 3.5 mm stereo jack, but no capability to connect microphones or other external audio sources, such as attaching directly to loudspeakers. The Wolfson Audio CardWolfson Audio Card solves this by providing similar audio flexibility that would be provided by a PC soundcard. The Wolfson Audio CardWolfson Audio Card is based on Wolfson WM5102 audio hub codes. Key Applications: Audio applications
Android Right, everything is built. But, since I'm not very good at this, it's not working (what a surprise). Getting the "not syncing - attempted to kill init" error. So far I've tried:Creating partitions with the debian partition, deleting all the debian and firmware files then replacing them with the latest firmware, the kernel I built and the android files.-Putting all the files (firmware/kernel/android) onto one partition (tried ext4,vfat and msdos)-Using the generic build instead of rpi. All of these had the same result, the same kernel panic, so it seems that the problem lies in the init file, as the panic suggests.Init.rc is as follows: on early-init start ueventd on init sysclktz 0 loglevel 3 # Backward compatibility symlink /system/etc /etc symlink /sys/kernel/debug /d # Right now vendor lives on the same filesystem as system,# but someday that may change. symlink /system/vendor /vendor # create mountpoints mkdir /mnt 0775 root system mkdir /mnt/sdcard 0000 system system class_start default
Speech Recognition using the Raspberry Pi | aO(N²) I've finally received my Raspberry Pi, and I've immediately gotten to work transferring the speech recognition system I used for the robotic arm to the pi. Due to its small size and low power requirements, the Raspberry Pi is an excellent platform for the Julius open-source speech recognition system. This opens up almost limitless possibilities for voice command applications. EDIT: I am no longer working on Julius/HTK for speech recognition. There do exist commercial offerings of electronic voice command modules, as well as voice command applications appearing in recent smartphones (i.e. In this tutorial, I will be demonstrating how to use the Raspberry Pi for a simple speech recognition system to control the Maplin USB Robotic Arm. Requirements: Raspberry Pi set up and running debian (please follow setup instructions from www.raspberrypi.org) and preferably connected to the internetUSB microphone Since we are not using the GPU very much, we'll allocate less RAM for video memory.

Note names, MIDI numbers and frequencies Note names, MIDI numbers and frequencies are related here in tables and via an application that converts them. The musical interval between two notes depends on the ratio of their frequencies. See Frequency and Pitch for more details and an introduction to frequency and pitch. An octave is a ratio of 2:1 and, in equal temperament, an octave comprises 12 equal semitones. Each semitone therefore has a ratio of 21/12 (approximately 1.059). By convention, A4 is often set at 440 Hz. This table is reproduced inverted below, i.e. with high pitch at the top. To convert from any frequency to pitch (i.e. to the nearest note and how far it is out of tune, go to the frequency to note converter written by Andrew Botros. How to do the caluation? no = log2(f2/f1). Conversely, one can obtain n, the number of semitones from A4, from n = 12*log2(fn/440 Hz). Similar equations give no, the number of octaves from A4, and nc, the number of cents from A4: no = log2(fn/440 Hz) and nc = 1200*log2(fn/440 Hz).
