FreeLSS: The Free 3D Printable Laser Scanning System For the Raspberry Pi. RaspBerry Pi et afficheur LCD Hitachi HD44780 1602. Comme vous le savez j’ai récemment récupéré un RaspBerry Pi et du coup je me suis dis pourquoi ne pas essayé d’intéragir avec les pins GPIO (General Purpose Input Output). Je me suis donc donné pour projet de réaliser un petit programme qui affiche des informations systèmes sur un écran LCD connecté via les ports GPIO de mon RaspBerry Pi. Les GPIO du RaspBerry Pi Un RaspBerry Pi possède 26 pins GPIO qui permettent de connecter une multitude d’équipement et périphériques: LED, transistor, radio, cerveeau, afficheur lcd, dalle tactile, … Le schéma suivant détail l’utilisation de chacun des pins.

11 : Relier à un écran et afficher du texte

Aujourd’hui nous allons apprendre à faire ça : Mais non pas la boite bande de péquenauds incultes (wink wink nudge nudge), mais ce magnifique écran LCD, à l’origine utilisé sur les vieux téléphones nokia (ben oui on est pas des nouilles molles). Le but de ce tuto sera donc de brancher un petit écran LCD rétro éclairé (a 2,50€ sur ebay cela dit) et d’y afficher un texte choisis. Near Field Communication - Physical Computing with Raspberry Pi. Difficulty: advanced.

Le problème, au fil du temps, les fichiers de logs sont nombreux et fastidieux à parcourir. Cependant, il est important d’effectuer cette tâche afin de savoir si tout fonctionne correctement et d’anticiper des besoins de maintenance. J’utilise depuis plusieurs semaines logwatch en complément de RPi-Monitor et Monit. Tous les matins, je reçois un mail qui résume la journée précédente. On peut choisir le niveau du résumé (petit, moyen ou détaillé), son format (texte ou hml) ainsi que des services à exclure. Pourquoi ce choix par rapport à Munin ou Cacti ?

Turn a Raspberry Pi into a Multi-Room Wireless Stereo. A Raspberry Pi controlled mini CNC Laser engraver [keep updating]

I recently made a mini CNC laser engraver using two DVD drives salvaged from old computers and <$10 extra parts bought on eBay.

A Raspberry Pi controlled mini CNC Laser engraver [keep updating]

The controller of the CNC machine is a Raspberry Pi, a $35 credit card size computer. The engraver turns out to be pretty successful. So I am sharing it with everyone. There have been a lot of examples people using Arduino to control CNCs. You can probably find tons of C programs available that run directly on Arduino to process G code.

Journal - Weekend Project: Solar Powered, Outdoor Raspberry Pi. Let’s break down what we’re doing with this wiring diagram in a little more detail.

Journal - Weekend Project: Solar Powered, Outdoor Raspberry Pi

First, let’s look at this one charger, battery and panel at a time. We’re using the newer version 2 of the USB / DC / Solar Lithium Ion/Polymer charger from Adafruit. PrivateEyePi – a DIY home alarm system. A big thank you to Recantha for spotting this one: PrivateEyePi is a project that went straight on my “I MUST make one of these” list when I saw it. Right now, that list includes an aerial Pi and camera board with the IR filter removed to take pictures of Iron Age sites in inaccessible bits of Cornish moorland; an Airplay-alike MagicPlay receiver; a garden irrigator and an Ambilight clone for the TV. I need a holiday so I can work on all this stuff – there just aren’t enough hours in the day.

PrivateEyePi is an open, configurable, automatable home alarm system that you can build and program yourself. Its maker (identified only as “Gadjet Nut”) has documented the whole system minutely and provides parts lists and pricing; wiring schematics; and all the code you’ll need. Onion Pi.

Travaillant en ce moment sous la solution de TOIP Elastix , j’ai voulu voir si Raspberry Pi serait capable de l’encaisser. Il s’avère qu’il existe une version (officielle!)

De Elastix pour les micro PC sous ARM : micro-Elastix . Delta-Sigma Pi 18 bit Analogue to Digital converter for the Raspberry Pi computer boards Delta-Sigma Pi. The Delta-Sigma Pi is an 8 channel analogue to digital converter designed for use on the Raspberry Pi computer platform. The board is based around the MCP3424 low noise and high accuracy 18 bit delta-sigma analogue to digital converter from Microchip Technology Inc.

A pair of MCP3424 converters are included on the board along with an I2C buffer interface allowing you to connect additional 5V I2C devices to the same bus. The I2C address bits are selectable using the on-board jumpers. The MCP3424 supports up to 8 different I2C addresses so with two A/D converters on each Delta-Sigma Pi you can stack up to 4 Delta-Sigma Pi boards on a single Raspberry Pi giving you 32 ADC inputs. The MCP3424 contains an on-board 2.048V reference voltage with an input range of ±2.048V differentially (full scale range of 4.096V/PGA). The data rate for analogue to digital conversions is 3.75 (18 bit), 15 (16 bit), 60 (14 bit) or 240 (12 bit) samples per second.

Write your own review. Untether Your 3-D Printer With a $35 Raspberry Pi. A RepRap controller running Pronterface on a Raspberry Pi. Photo: WDZaphod While most people still have trouble setting up an inkjet printer on a wireless network, a group of intrepid IT hackers are making big strides with far more advanced machines, using the tiny Raspberry Pi microcomputer to untether laptops from their 3-D printers. Zachary Bales is an undergraduate studying electrical engineering and physics at Cal State Long Beach. He got into building a RepRap while acting as president of his engineering class. 3-D printing technology felt futuristic, but leaving a laptop attached to a printer for the duration of a modest five-hour print job seemed as dreadful as history class.

Carrier connect shout out. Cottonpickersplace. Dr. Monk's DIY Electronics Blog: Raspberry Pi and Breadboard (Raspberry Leaf) I thought I would share this little helper I have made to simplify using the Pi with jumper wires. If you are using your Raspberry Pi with Breadboard, and you have lots of connections to make, then the Pi Cobbler from Adafruit is pretty neat. However, sometimes you only need to make a couple of connections and the Cobbler is overkill and a few Male to Female jumper leads will do just fine.

The drawback with using Male to Female jumpers direct onto the GPIO is that you then have to count down the pins trying to find the pin you need, because nothing is labelled. So you got a Raspberry Pi: now what? VoIP on Steroids: Introducing Incredible PBX 3.7 for the $35 Raspberry Pi. It’s been a wild ride with the $35 Raspberry Pi®. In late October, sales of the Raspberry Pi topped two million in less than two years. And, if you didn’t already know, the Raspberry Pi makes a near perfect platform for your very own VoIP PBX. It’s less than a ONE HOUR project! If you’re new to the party, imagine squeezing a 700 mHz ARM processor with 512MB of RAM, 2 USB ports, a 10/100 Ethernet port, an HDMI port, composite video, a separate audio jack, an SDHC card slot, and a micro USB port onto a motherboard the size of a credit card weighing 1.6 ounces.

Turn a Raspberry Pi Into a Low Power NAS. 14 : Surveiller les performances du rpi depuis le web. Ce post est le quatorzième (mazette, déjà !) D’une liste de tutoriels sur le raspberry PI, cliquez ici pour accéder au sommaire ! C’est bien beau de traficoter tout un tas de truc avec notre raspberry PI !

Mais celui ci étant une frêle petite bébête, il peut être intéressant de le contrôler un peu question performances. EDIT : Il semble que le projet ai été abandonné, les liens de téléchargements ne sont plus proposés.Si vous souhaitez installer du monitoring, je vous conseille d’installer Yana-server qui le permet et qui sera très utilisé dans la suite des tutos. Et ça tombe bien, il existe une interface web mimi comme tout justement faite pour ça !! RaspControl vous permettra de monitorer de nombreuses infos sur l’état de santé de votre raspberry pi,n’importe quand et n’importe ou. Ce petit logiciel en PHP est “standalone” c’est à dire qu’il peux tourner sans que vous ayez au préalable installé un serveur web.
