Raspberry Pi
The Raspberry Pi is a series of credit card-sized single-board computers developed in the UK by the Raspberry Pi Foundation with the intention of promoting the teaching of basic computer science in schools.[3][4][5] The original Raspberry Pi and Raspberry Pi 2 are manufactured in several board configurations through licensed manufacturing agreements with Newark element14 (Premier Farnell), RS Components and Egoman. These companies sell the Raspberry Pi online.[6] Egoman produces a version for distribution solely in China and Taiwan, which can be distinguished from other Pis by their red colouring and lack of FCC/CE marks. The hardware is the same across all manufacturers. In 2014, the Raspberry Pi Foundation launched the Compute Module, which packages a BCM2835 with 512 MB RAM and an eMMC flash chip into a module for use as a part of embedded systems.[10] Hardware[edit] Processor[edit] Performance of first generation models[edit] Overclocking[edit] RAM[edit] Networking[edit] Peripherals[edit] Related:  Raspberry Pi

Raspberry Pi Temperature Sensor In this tutorial, we will be building a circuit to connect a temperature sensor to our Raspberry Pi, and writing a program to read the sensor data. The circuit we will build is going to connect to the Raspberry Pi using the GPIO pins. GPIO stands for General Purpose Input/Output. General purpose because all they are is simple connections that can be either high or low, a binary choice. This means we can easily do things that involves binary choices, and it will still be nice and simple to understand what is going on. However, this is not all that GPIO pins can be used for. Once we have built our circuit, the next step is to write a program to read the temperature, and give it to us in a nice format. Finally, we will put all these bits together to make a button controlled temperature logger—a program that will measure the temperature every second and put this in a file, which can be started and stopped by the press of a button. Step One: Updating the Kernel Turn on the Pi. Turn on the Pi.

How To Become An App Millionaire - Development - Mobility Fire Maple Games owner Joe Kauffman says his secret is great entertainment. But his success story also includes Corona SDK, a programming tool that fuels iOS, Android, and soon OS X apps from one code base. Joe Kauffman is living the mobile app developer dream. His company's two mobile games, The Secret of Grisly Manor and The Lost City, have been downloaded over 3.5 million times to date, and have generated more than $1 million in revenue. His company, Fire Maple Games, has one employee, if you ignore the photographic work done by a friend and the contracted music. "Because I do the art and the programming, there are no arguments," Kauffman quipped in a phone interview. Without doubt, Kauffman is an exception in an industry where the average developer earns less than $10,000 per year. [ Read 10 Android App Hidden Gems. ] San Francisco, incidentally, is where the Game Developer's Conference is being held this week. Icaza says that Kauffman's success reflects well upon Ansca Mobile.

List of mobile software distribution platforms Operating system-native platforms[edit] These application market places are native to the major mobile operating systems. Notes Jump up ^ Only Samsung Smart TV and discontinued Bada platform apps are classified as Native Operating system platform. Android apps in Samsung Apps store should be classified as third-party platform apps as alternative for Google Play.Jump up ^ Microsoft classifies developer accounts to individual accounts and company accounts. Individual accounts are restricted from using specific app capabilities and cannot list desktop apps in Windows Store, while company accounts do not have this restriction.[55] Microsoft verifies company accounts by contacting the company official, while this is not done for individual accounts.[56] Third-party platforms[edit] Third-party platforms are software distribution platforms which are used as alternative for Operating system native distribution platforms and are not using own independent Operating system.

La invisible revolución de Raspberry Pi En todos los sentidos, Raspberry Pi es un éxito. Este pequeñísimo PC, que casi entra en la palma de tu mano, está especialmente diseñado para ser compacto y extremadamente simple. Su función es la de tener una plataforma y que cualquier persona pueda crear proyectos con esta diminuta computadora. Sin una docena de conexiones, salidas de vídeo o procesadores de última generación, Raspberry Pi es el gran éxito que el hardware abierto necesitaba. Un proyecto creado bajo el ala de una fundación que pensaba podrían vender unas 10.000 unidades en toda su vida, se confirma como un éxito al conocerse que llevan 3.8 millones de unidades vendidas. Tan solo necesitas una conexión USB para encenderlo, una tarjeta SD con un sistema operativo, y conectarlo a un monitor, ratón y teclado para empezar a usarlo. Pero Raspberry abrió los ojos a muchas personas sobre lo que es capaz de hacerse con un pequeño PC cuyas características son simples. Ver en YouTube Foto portada (cc) Rain Rabbit

Gav's World : Raspberry Pi : Car Media Server Raspberry Pi Car Media Server [gav-pi2] It was extremely simple to set up... eventually... once I'd battled with RaspBMC for a couple of nights (it's too constrained to do a particular job - although it does it very well) and switched to Raspbian... The thick yellow (orange externally), red and black wires carry +12V, +12V (accessory) and GND from the car. The thin white and blue wires are handshaking signals between the Pi and the power supply for controlled shutdown. What did it used to only do? It is a Wi-Fi hotspot to allow our phones and tablets to connect to. What does it also do now? With the addition of a small USB hub and a USB 3G modem, the car server now provides Internet access for any devices connected to it in the car. Initial setup Plug an SDHC card into desktop PC (or laptop). Configuring the Wi-Fi Hotspot Configuring DHCP / DNS Configuring a 3G / 4G USB Modem This turns out to be far simpler that first thought.

Iniaciación al uso de Raspberry Pi en educación (I) | aKoranga – educación y tecnología – francesc balagué Una de las cosas más difíciles de empezar a usar la Raspberry Pi, ha sido encontrarla en una tienda en stock, ya que las pocas que iban llegando se vendían en horas, y los envíos desde UK tardaban entre dos semanas y un mes. Poco a poco la situación ya se fue regulando y ahora ya es mucho más fácil de encontrar. Concretamente yo la compré en la tienda Onda Radio de Barcelona, por unos 37 euros, la Raspberry Pi B. ¿Qué es la Respberry Pi? Según la Wikipedia, Raspberry Pi es una placa computadora (SBC) de bajo coste desarrollada en Reino Unido por la Fundación Raspberry Pi, con el objetivo de estimular la enseñanza de ciencias de la computación en las escuelas. Comunidad La comunidad de Raspberry Pi fue descrita por Jamie Ayre de la compañía AdaCore ligada a FLOSS como una de las partes más excitantes del proyecto.

4 Ways that NASA Technology Makes Earth-Life Better | Green Business Bureau If you spend much time watching television or wandering through the bedding section of a local home store you may have seen memory foam, a type of comfortable mattress padding, touted as being created for the space shuttle. If you wondered how true this was the real fact is that it is – totally true. In fact, you may be surprised at how many space aged, NASA developed technologies have made it into our modern daily living. Here is a brief over of four such products, which NASA itself calls “spin off” products. Memory Foam Yes, memory foam was originally designed so that astronauts could sit comfortably, particularly upon blast off and landing. Saving Gas for the Airlines In 1998 scientist Heinz Erzberger won the NASA software of the year award when he invented a software system that helps air traffic controllers find the best route for an airplane to travel. Hybrids on the Road NASA spacecraft use a variety of energy sources for power, making them in some ways the ultimate hybrids.

Mathematica Features[edit] Features of Mathematica include:[7] Interface[edit] The front end, designed by Theodore Gray, provides a GUI, which allows the creation and editing of Notebook documents containing program code with prettyprinting, formatted text together with results including typeset mathematics, graphics, GUI components, tables, and sounds. Documents can be structured using a hierarchy of cells, which allow for outlining and sectioning of a document and support automatic numbering index creation. The front end includes development tools such as a debugger, input completion and automatic syntax coloring. Wolfram Research has published a series of hands-on starter webcasts that introduce the user interface and the engine.[16] High-performance computing[edit] Deployment[edit] There are several ways to deploy applications written in Mathematica: Connections with other applications[edit] Computable data[edit] A stream plot of live weather data Design[edit] Related products[edit]
