Top 10 Things to Connect to Your Raspberry Pi

Top 10 Things to Connect to Your Raspberry Pi
During my time with the Pi I’ve experimented with various devices and sensors. Here is my Top 10 list of devices to connect to the Raspberry Pi. In most cases they are very cheap and easy to interface and are great building blocks for more complicated future projects. I’ve included links to more detailed posts where I can and many of these include example Python scripts to help you get going. From robot cars to security systems there are plenty of ways of combining these mini-projects into some amazing creations! Ultrasonic Module Ultrasonic Sensor Ultrasonic transducer modules are an easy way to add distance measuring capability to your Pi. Take a look at my “Ultrasonic Distance Measurement Using Python” posts to see how you can connect one to the GPIO header and read it via a simple Python script. PIR Movement Sensor PIR Module Simple “Passive Infra-Red” sensors allow you to detect movement. An example python script can be found on the “Cheap PIR Sensors and the Raspberry Pi” page.

Build an LED Indicator with a Raspberry Pi (for Email, Weather, or Anything) The Raspberry Pi makes a nice compact platform to attach an indicator light to for all sorts of projects—weather notification, new emails, etc. Read on as we show you how to hook up an LED module to your Pi and set up some basic notifications. Why Do I Want to Do This? Because it’s fun. Unlike many of our tutorials where we include a little blurb at the top outlining exactly what benefit you’ll derive from the project, the blurb is pretty short in this case because the benefit is simply having fun. The Raspberry Pi is a perfect device to play around with, experiment with electronics, and learn some programming. What Do I Need? To follow along with out tutorial you’ll need a few things. In addition to having a functional Pi unit with Raspbian installed on it you’ll need the following things: Note: The clear/frosted Pi case is entirely optional but if you’re currently using an opaque case then your LED indicator will be hidden inside.

Voyant pour indication de la température Hello, aujourd'hui j'ai décide de me pencher sur un des avantage de notre petit raspberry pi qui est la possibilité d'utilisé des broches GPIO, pour contrôler de l’électronique et faire de la domotique. Pour commencer petit j'ai récupérer deux led une rouge et une vert, mon objectif est que la LED verte informe d'une bonne température exemple inférieur à 40°C et la rouge pas conséquent pour les température supérieur. Dans un premier je me suis informer sur comment utiliser ces fameuse broche, je suis donc tombé une schématisation de ces broche (ce schéma va vous servir longtemps :D) : Ensuite grâce a ce croquis j'ai fait un schéma de mes LED : Une fois le câblage fait il faut passer a la partie programmation et la un outils maintenant indispensable est à installer c'est une librairie qui va permet d'actionner directement les entrée sortie gpio, je vous laisse suivre le tuto du créateur de cette bibliothèque, c'est simple et rapide (lien). #!

Raspberry Pi without keyboard, mouse nor screen. &emdash; Edmundo Fuentes I’ve been wanting to mess around with a Raspberry Pi ever since the day it was announced. The thing is, right now I’m studying abroad, so buying a dedicated set of peripherals (keyboard, mouse, screen, etc..) was not an option. However, it occurred to me that I could use my own MacBook as my RPi’s HMI. After checking some sources and asking around on the IRC channel, I found out that it could be done, so without hesitating I ordered myself one. I’ve written this little guide to help you configure your RPi with a lightweight VNC server to get you started in case you lack the hardware peripherals. 0. I’m not going to get into much detail here since it’s been widely discussed on the web. 1. This is actually the “hardest” step since it’s pretty much guessing and a little bit of luck. I’m using my MacBook’s built in “Internet Sharing” feature, I’m sharing my internet connection from WiFi to my ethernet port, to which the RPi is directly connected. 2. > ssh pi@192.168.2.X Congrats! 3. 4. #!

SMS Gateway : une passerelle SMS à la maison Si vous avez votre serveur domotique en place et qu’une alerte doit vous être remontée il existe plusieurs manières de le faire : SMS, Pushme.to, push via l’application Smartphone de votre serveur domotique… Ces solutions marchent très bien mais ont un point faible: elles nécessitent une connexion internet. Les SMS par exemple sont générés par votre box domotique puis sont envoyés en HTTP sur internet au serveur central de votre solution domotique. Là ils sont envoyés au format SMS sur le réseau GSM via une passerelle. Avec l’arrivée des forfaits à tarifs réduits (merci Free! La passerelle SMS pour être compatible avec le maximum de solutions domotiques (on n’est jamais à l’abri d’en changer ou d’employer plusieurs à la maison) doit pouvoir discuter de manière simple et standardisée. La passerelle SMS doit pouvoir avoir une alimentation secourue afin de faire face à des coupures électriques. La passerelle SMS doit pouvoir être simple d’utilisation et de paramétrage. Tout est possible!

Best of 2012: Raspberry Pi Projects It’s been a big first year for Raspberry Pi, the $35 mini Linux computer. As soon as they started shipping, makers were eager to get their hands on the board so that they could use it in their projects. In just a few months, we’ve seen a ton of great Raspberry Pi projects come our way. Below, we’re recounting some of our favorite projects in no particular order. We’re looking forward to seeing what you do with Raspberry Pi in 2013. BeetBox Sets Standard for Vegetable-based Instruments For the ITP classes Tech Crafts and Materials and Building Strategies, Scott Garner created the BeetBox, a tuber-based electronic drum machine. How-To: Solar-Powered Raspberry Pi FTP Server This build uses a custom 3D-printed / hand assembled case from RPi hacker Cottonpickers, which comes attached to the back of a 300mA solar panel.

Fabriquer un émetteur FM pirate avec un Raspberry Pi Saviez-vous qu'il était possible de fabriquer une radio FM pirate à avec un Raspberry Pi ? C'est ce que propose le site Make avec ce tuto qui dispense tous les bons conseils et les étapes à suivre pour lancer votre station FM à moindre coût. Je rappelle quand même que ce n'est pas autorisé par les lois divines en vigueur dans notre pays (enfin, je ne crois pas), donc ce tuto s'adresse uniquement aux étrangers qui me lisent. Pour ce faire, vous avez besoin d'un Raspeberry Pi, du logiciel PiFM et d'une simple antenne filaire. Il suffit tout simplement de fixer ce fil sur le connecteur 4 du GPIO et de booter sur la carte SD avec PiFM. C'est une bidouille hyper simple à réaliser qui vous permettra de balancer de la musique sur tous les postes FM de chez vous (ou du taf...) + d'infos ici. Edit: Et le tuto en français est dispo ici.

Some Christmas lights projects I haven’t even put my tree up yet, but lots of you have been very busy with the Christmas decorations and your Raspberry Pis. Here are some projects you’ve still got time to emulate before Santa comes. ConsiderIT.co.uk take the whole Internet of Things idea seriously, and have wired up their office with a positive welter of fairy lights and a networked Raspberry Pi. They invite you to come and turn the lights on and off, watching the torment of their employees over a live feed. I took this screengrab from the feed from their office yesterday, and I don’t know whether to feel deep pride or terrible, terrible shame over the fact that these poor people are being subjected to this visual horror in their office courtesy of a Raspberry Pi. A quiet moment. A screen grab from the live feed. If you’re looking to do something a little less flashy, but still useful, here’s an easy one, which I found linked to from our forums . A very easy piece of GPIO wiring! Rumtopf: you should sell these.

Se passer de serveur DNS grâce au Multicast DNS Parfois on cherche à reproduire nos infrastructures professionnelles alors qu’il existe des solutions tout à fait satisfaisante pour répondre à des besoins ponctuels. Le mdns fait partie de ses solutions. Je cherchais une solution de résolution de noms pour éviter de devoir créer des baux statiques pour tous mes périphériques. Et j’ai trouvé la solution en regardant dans les paramètres des baux DHCP de ma freebox. En effet j’ai vu le nom de mdns que je ne connaissais pas. Je suis tombé sur la doc de zéroconf et là je me suis dit génial tout à fait ce que je cherche. Le mDNS, pour Multicast DNS, a été développé par la société Apple en s’inspirant des travaux publié par Bill Manning et Bill Woodcook (2 bill’s) sur le protocole Multicast Domain Name Service. L’implémentation de ce protocole sur Linux utilise la bibliothèque logicielle Avahi et est compatible avec celle de Bonjour. Même pas besoin de rebooter pour que cela soit pris en compte.

blog.zephod.com | Build your own RC Car using Lego, an Xbox Controller and a Raspberry Pi When I was a child I always wanted a remote control car. I never got one — usually my parents convinced me that the novelty would wear off in an hour, and that it wouldn’t be worth the expense. (They were probably right). I usually opted for a safer videogame-based option at Christmas time, and on my birthday I’d ask for Lego. The Raspberry Pi — a tiny, low-power computer that fits in the palm of your hand — provided the inspiration for a project to finally put that right. Using bricks from my childhood Lego collection, and a wireless Xbox 360 controller from my teenage years, at long last I could hack together a remote control car! Not exactly simple I’m a programmer by trade, but any knowledge of electronics learned during University apparently died at graduation. There have been similar attempts to control RC cars from an Xbox controller: This project takes it a step further because the Raspberry Pi is a complete computer, so all the hardware lives on the car.
