For more functions, please refer to standard Python documentation. Printing to the Screen The simplest way to produce output is using the print statement where you can pass zero or more expressions separated by commas. This function converts the expressions you pass into a string and writes the result to standard output as follows − CGI Output. Build A Photobooth with an Arduino Yun, a Webcam and Dropbox. The Arduino Yun is an Arduino with built-in WiFi and Linux.

Build A Photobooth with an Arduino Yun, a Webcam and Dropbox

With the Yun, not only can you do all the hardware hacking that you’d expect from an Arduino, but you can also connect it to the Internet and run programs in your favorite scripting language. In this tutorial, we’ll build a proof-of-concept for an Arduino powered photo booth to serve as the foundation for teaching my dog to send me selfies using Twilio MMS. The goal is to: take a picture with a webcam plugged into the Arduino Yunupload the image to dropbox using Pythontrigger these actions via the press of a button. Developing with Bottle - part 2 ( API) Updated on 02/27/2014 and again on 08/01/2014 (for the latest Plotly API)!

Developing with Bottle - part 2 ( API)

In this next post in the Developing with Bottle series, we’ll be looking at both GET and POST requests as well as HTML forms. I’ll also show you how to consume data from the API. You’ll also get to see how to create a cool graph showing the results of a cohort analysis study. Check out this article here if you are unfamiliar with cohort analysis.

Member project: John’s Tetris Table. Tetris is one of the world’s greatest games.

Member project: John’s Tetris Table

Perhaps one of the reasons Tetris is such a ubiquitous computer game is because you don’t need a particularly high resolution display. You might even say it works better at low resolutions. Perhaps this is what John was thinking when he filled a table with neopixel-like LED strips to create a large low-res display for playing Tetris. If this looks familiar, perhaps you spotted it at the Derby Maker Faire. John built the table himself from scratch and even gave it York Hackspace branding. The inside of the table is mostly hollow. The game is written in python and is running on a Raspberry Pi 2. Raspberry Pi YouTube Live Stream. I have my Lego Raspberry Pi 3 up and live-streaming on YouTube.

5 façons de faire du streaming vidéo avec un Raspberry Pi. Le module Raspberry Pi Camera (et la version sans filtre IR, le module NoIR) sont de petits circuits (2,5cm x 2,5cm) dotés d’un capteur photo de 2592 x 1944 pixels capable d’enregistrer en 1080p à 30 images par secondes (ou 60 fps en 720p).

Ce module se branche directement sur le port CSI du Pi prévu à cet effet. Pwn Your GoPro: Scripting, WiFi, and Bus Hacking. GoPro cameras come out of the box with a huge set of features.

Pwn Your GoPro: Scripting, WiFi, and Bus Hacking

Most people will be satisfied, or possibly even overwhelmed by the available options, but if you’re able to do some of these hacks, you’ll be able to expand your camera’s capabilities even more. They can, however, void your warranty, so as with most hacking, do these at your own risk. Scripting with Autoexec.ash By far the simplest way to extend your GoPro’s capabilities is by placing a text file in your GoPro camera’s root folder called Autoexec.ash. You can download a number of scripts on, which should be very easy to modify per [Konrad’s] insights. 5 façons de faire du streaming vidéo avec un Raspberry Pi. Installer OSMC et faite un media-center avec votre Raspberry Pi. Cela fait très longtemps que nous voulions vous parler de la Raspberry Pi comme media-center, mais nous n’en avions pas nous même.

Installer OSMC et faite un media-center avec votre Raspberry Pi

Cependant, avec l'arrivée de la Raspberry Pi 3, et pour le retour de la série Game Of Thrones, nous avons décidé d’utiliser une Raspberry Pi pour faire un media center et pouvoir revoir l’intégrale de la série sur notre vidéo projecteur sans avoir des fils dans tous les coins ! Aujourd’hui nous allons donc vous expliquer comment installer Raspbmc (ou plutôt OSMC) sur votre Raspberry Pi, pour en faire un media-center, ce qu’est Raspbmc, le matériel dont vous aurez besoin, et enfin comment installer Raspbmc sur votre Raspberry Pi, depuis Windows, Linux et Mac ! Raspbmc, un mélange entre Raspbian et le media-center XBMC Avant de nous jeter à l’eau en installant XBMC sur notre Raspberry Pi, faisons une petite présentation de ce système.

PiCast: The open source, Raspberry Pi Chromecast alternative - If you were one of the many fortunate enough to grab Google’s new Chromecast HDMI dongle before it sold out, you’re already well aware of what a great experience it provides.

PiCast: The open source, Raspberry Pi Chromecast alternative -

It’s not perfect, and while we wait for Google to allow developers to release third party software to fill in the gaps, one man decided to implement his own Chromecast solution using the Raspberry Pi computer. Defining Monitors — ZoneMinder documentation. To use ZoneMinder properly you need to define at least one Monitor. Essentially, a monitor is associated with a camera and can continually check it for motion detection and such like.

You can access the monitor window by clicking on the “Add New Monitor” button, or by clicking on the “Source” column of a predefined monitor. There are a small number of camera setups that ZoneMinder knows about and which can be accessed by clicking on the ‘Presets’ link. Selecting one of the presets will fill in the monitor configuration with appropriate values but you will still need to enter others and confirm the preset settings. LibVLC. The libVLC (VLC SDK) media framework can be embedded into an application to get multimedia capabilities. Since VLC is based on libVLC, one should be able to have the same features that VLC media player has. The libVLC media framework is already used by several applications; see who uses libVLC? Documentation Please refer to the Doxygen documentation, which is the reference documentation.

Make sure that the documentation matches the LibVLC version. Category:x264. x264 is a free software library for encoding H.264/MPEG-4 AVC video streams. The code is written by Loren Merritt, Laurent Aimar, Eric Petit, Min Chen, Justin Clay, Måns Rullgård, Radek Czyz, Alex Izvorski, Alex Wright, Jason and Christian Heine from scratch. x264 is one of the most popular video compression libraries in the world, used worldwide for applications such as web video, television broadcast, and Blu-ray authoring.

Documentation:Streaming HowTo New. This documentation explains how to stream, transcode and save streams using VLC media player. NOTE: This is work in progress. For a more complete, yet outdated, documentation on Streaming with VLC please see the old Streaming HowTo. Introduction VLC media player is able to stream, transcode and save different media streams. For more information about the formats and codecs supported please see the VideoLAN Streaming Features list. Documentation:Streaming HowTo/Command Line Examples.

[GUIDE] Chromecast streaming from raspberry pi. Abcdeeeeff wrote:In this guide I'm explaining how to stream your movies, music and photos from your raspberry pi to your chromecast. If your media are not encoded in a chromecast-compatible format(see here bubbleupnp server will transcode them.Be aware that the pi is not powerful enough for on-the-fly video transcoding. So if your videos are not encoded in x264, you have to convert them, or to setup bubbleupnp server on a more powerful PC. Hi Guys Recently I was asked by one of the members of the forum, if I can help him out to setup minidlna with BubbleUPNP server on Android device.
