Planet Libre - Transformer un Raspberry Pi en passerelle vers Hubic d'OVH : Nginx, script Toorop & Cloudfuse 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...
Planet RaspFR 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
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).
R-Pi Troubleshooting Back to the Hub. This page lists the most common problems and suggests some solutions. See RPi_Bugs for problems that are bugs. Power / Start-up A good power supply that will supply 5 volts and at least 1 amp (5V 1A) is vital. A 5 volt 2 amp power supply can help some wifi USB adapters run more stable. Note that the Pi has no BIOS, so nothing will be displayed on screen unless the Pi successfully boots! Normal LED status There are five LEDS near the USB connector. See the next sections for how to interpret other statuses. Red power LED does not light, nothing on display The power is not properly connected. Red power LED is blinking The red power LED should never blink, because it is hard-wired to the 3.3V power supply rail. Red power LED is on, green LED does not flash, nothing on display Note: A faintly glowing steady green LED means no boot code has ever been executed, as almost the first thing the boot code does is to turn the faint glow off! Green LED blinks in a specific pattern xset -r Webcam
Noobs, un logiciel pour utiliser sa Raspberry Pi quand on est débutant Noobs est un pur produit du vocabulaire geek et un dérivé de l’argot Anglais pour New boy qui a donné Newbie puis Noob par contraction. C’est la remarque habituelle faite en ligne a quelqu’un qui ne connait pas trop son sujet. Parfois paternaliste, d’autre fois blessante, c’est désormais également le nom d’un logiciel destiné a aider les possesseurs de cartes Raspberry Pi. La carte Raspberry Pi a beaucoup d’avantages a commencer par être un vrai PC vendu à un prix défiant toute concurrence. Derrière le nom Noobs il y a un acronyme pour « New Out Of Box Software » et une idée assez simple que l’on a bien connu du temps des netbooks, quand il fallait installer sur le système des distributions linux sans exploiter de lecteur CD mais avec une clé-USB. En clair, on prépare une carte d’une capacité suffisante (4 Go ou plus), on l’insère dans un lecteur sur son PC avant de la formater. Source : Liliputing.
Music hack of the decade: Panflute Hero! Jhonny Göransson was part of the team that made what’s simply the daftest and most wonderful music hack we’ve seen so far. The moment he tweeted about it last night, we knew we had to show it to you as soon as we could. It’s called Panflute Hero. Panflute Hero was the result of a weekend at Way Out West Hackathon 2013. It’s a very silly panpipe version of Guitar Hero, which doesn’t use a plastic guitar controller. The game itself is built in Lua, and runs on a PC (no reason you couldn’t run a port on a Pi). Instructions, code (Jhonny says: “In the spirit of hacking and hackathons, our code really blows (get it?). MagPi issue 25 – out now! For your weekend reading pleasure, here’s issue 25 of the MagPi! Published just yesterday, the latest issue of everyone’s favourite free, monthly, community-produced Raspberry Pi magazine is as full of fantastic stuff as ever. Click to read The MagPi! The cover story is one that’ll definitely get some attention in our house this weekend: it’s a full Python simulation of the Pocket Enigma Cipher Machine, a cleverly devised toy that demonstrates some of the principles of a real Enigma machine like the one many of you will recognise in the cover photo. Used by the German armed forces during World War II to encipher messages, these used rotating disks to achieve a sophisticated substitution cipher; the Pocket machine, and its Python simulation, use two disks to arrive at a fun, if not exactly unbreakable, cipher. We’re delighted to see an article by Andrew Suttle, the MagPi’s youngest guest writer so far.
Raspberry Pi Un article de Wikipédia, l'encyclopédie libre. Le Raspberry Pi est un nano-ordinateur monocarte à processeur ARM conçu par le créateur de jeux vidéo David Braben, dans le cadre de sa fondation Raspberry Pi[2]. Cet ordinateur, qui a la taille d'une carte de crédit, est destiné à encourager l'apprentissage de la programmation informatique[2] ; il permet l'exécution de plusieurs variantes du système d'exploitation libre GNU/Linux et des logiciels compatibles. Son prix de vente était estimé à 25 $, soit 19,09 €, début mai 2011. Historique[modifier | modifier le code] Conception[modifier | modifier le code] Version alpha de la carte. En 2006, les premiers prototypes du Raspberry Pi sont développés sur des microcontrôleurs Atmel ATmega 644. L'objectif de la fondation est alors de proposer deux versions, l'une à 25 $ US et une deuxième à 35 $ US. Prototype[modifier | modifier le code] En octobre 2011, une version de RISC OS 5 tournant sur la carte est présentée. Différences avec le A[59] :
MagPi issue 20 – your free Raspberry Pi magazine, out now Issue 20, February 2014, of the excellent MagPi Magazine was released this week. I’m completely stealing the editorial by Matt from The MagPi team to introduce this issue (as you may have guessed, Liz is away. And I am not as good as Liz at this. After a massive response, we are pleased to write that the article series ‘Bake your own Pi filling’ is back by popular demand! We have more from the Caribbean with Project Curacao. Deepak Patil introduces his project for panoramic photography using Pi-Pan, a robotic arm controlled by his Raspberry Pi to move his Pi Camera. We have more from Andy Baker’s Quadcopter series with this issue reviewing his pre-flight checks. We have a great article detailing John Hobson’s and Efrain Olivares’ journey into managing the frustrating problem of internet dropout. Clive again: just to add that The MagPi is a magazine produced by the Raspberry Pi community for the Raspberry Pi community.
