Raspberry Pi 2 Model B

Raspberry Pi 2 Model B
The Raspberry Pi 2 Model B is the second generation Raspberry Pi. It replaced the original Raspberry Pi 1 Model B+ in February 2015. Compared to the Raspberry Pi 1 it has: A 900MHz quad-core ARM Cortex-A7 CPU1GB RAM Like the (Pi 1) Model B+, it also has: 4 USB ports40 GPIO pinsFull HDMI portEthernet portCombined 3.5mm audio jack and composite videoCamera interface (CSI)Display interface (DSI)Micro SD card slotVideoCore IV 3D graphics core Because it has an ARMv7 processor, it can run the full range of ARM GNU/Linux distributions, including Snappy Ubuntu Core, as well as Microsoft Windows 10 (see the blog for more information). The Raspberry Pi 2 has an identical form factor to the previous (Pi 1) Model B+ and has complete compatibility with Raspberry Pi 1. We recommend the Raspberry Pi 2 Model B for use in schools: it offers more flexibility for learners than the leaner (Pi 1) Model A+, which is more useful for embedded projects and projects which require very low power.

Controlling DC Motors Using Python With a Raspberry Pi In this tutorial I will show you how to connect some motors to your Raspberry Pi. Doing so will allow your Raspberry Pi to interact in the real world, making it possible to build a robot, turn on a fan on a hot day or even drop a treat for your cat or dog while your away. What we plan to do is safely connect one or two motors to the Raspberry Pi with as few components as possible. Once we have the electronics put together on the breadboard, I will show you how to control them easily using Python to first make the motor spin, and then add some control to change the motor direction so we can go backwards. This guide will require a careful eye to catch any mistakes, and a bit of courage, especially if you are new to the GPIO connectors. I would like to stress I am not responsible for any damage caused to your Raspberry Pi and/or components.

Raspberry Pi Zero: the $5 computer Of all the things we do at Raspberry Pi, driving down the cost of computer hardware remains one of the most important. Even in the developed world, a programmable computer is a luxury item for a lot of people, and every extra dollar that we ask someone to spend decreases the chance that they’ll choose to get involved. The original Raspberry Pi Model B and its successors put a programmable computer within reach of anyone with $20-35 to spend. Since 2012, millions of people have used a Raspberry Pi to get their first experience of programming, but we still meet people for whom cost remains a barrier to entry. At the start of this year, we began work on an even cheaper Raspberry Pi to help these people take the plunge. Autonomous, Cardboard, Rasberry Pi Controlled QuadCopter Cardboard from the recycling bin, The sheet we we used was 32"x20" with a thickness off around 4.1mm. A large clean box should do. Motors from Hobby King, 4x + Propeller clamps, We used Turnigy D3530/14 1100KV Brushless Outrunner Motor at $14.56 each. Our motors also came with propeller clamps which allowed us to easily connect our propellers to the motors.

Adding a Media Center to the Camper Raspberry Pi For Christmas, I had my wife give me a couple of Raspberry Pi computers. For those that don’t know, this is a computer on a board about the size of a credit card. This is not a high-end computer, but it is silent, generates very little heat and is build with a processor that is optimized for video. The Official Raspberry Pi Projects BookThe Magpi Magazine The Official Raspberry Pi Projects book is out now with 200 pages of ideas, inspiration and guides to help you with your next Raspberry Pi project! Buy The Official Raspberry Pi Projects Book in print from the Swag Store and all good newsagents! The world’s favourite credit card-sized PC, the Raspberry Pi is one of the best-selling computers even made in the UK.

Remote Controlled Quadcopter Based On Raspberry Pi We have seen a lot of remote controlled quadcopters based on many micro processors or dedicated flight controllers, but not many people would have thought of running a Linux machine on a quadcopter! Since Raspberry Pi has been very popular these years, and the it’s compact size and computation power compared to most micro-controllers, it would make a good flight controller. The PiCopter is a remote controlled quadcopter based on a Raspberry Pi. The Raspberry Pi handles all the flight control without using a micro controller like Arduino.

Raspberry Pi 3 is out now! Specs, benchmarks & more - The MagPi MagazineThe MagPi Magazine The Raspberry Pi 3 is here! Hopefully some of you were still surprised by the announcement today. Over the past four years, the Raspberry Pi has sold eight million units – three million in the last year alone – and now on its fourth birthday a brand new upgraded Pi has been released. You can read absolutely everything you’d want to know about it in issue 43 of the magazine coming out on Thursday but for now we thought we’d give you the hard facts about this brand new Raspberry Pi. And yes, it has wireless internet. Specifications

How to build your own Quadcopter AutoPilot / Flight Controller Back to my home page Fig 1: 3DR Quadcopter Contents Game Boy Zero We see a lot of Pi Zero retro gaming mods, but I think this one might just take the biscuit. This rather beautiful mod from Wermy (leave your real name in the comments if you’d like us to use it, Wermy!) has a few details that really make it stand out. Raspberry Pi Quadcopter – DIY Drones Raspberry Pi is a superpowerful and popular new computer board, like Arduino but with a much faster processor and built-in video. It's not really designed for "physical computing" with lots of I/O like Arduino, and it's not open hardware so you can't make a version optimized for any particular task, so it's not a natural candidate for an autopilot. (It also runs Linux, which isn't a real-time operating system). Nevertheless, Matthew Watson hacked together a PCB to work with the Raspberry Pi board and got a quadcopter to fly. From Hackaday:

Raspberry Pi: Everything You Need To Know My Raspberry Pi arrived with the evening mail—by midnight, my husband and I had turned it into a working print server. And neither of us had any background in computer science. Raspberry Pi is a computer the size of a credit card that’s so simple, anyone can program it. Designed as an introduction to science, technology, engineering, and math for UK grade schoolers, its $35 price tag has made it appealing to hobbyists all over the world. Despite its diminutive device, Raspberry Pi is powerful enough to process many of the same programs as PCs, from word processors to games. Its small size also makes Raspberry Pi ideal for programming connected home devices—like the aforementioned print server, which has given us the power to make every computer, laptop, and cell phone in our network printer-compatible.

Raspberry Pi NOOBS Setup To get started with Raspberry Pi, you need an operating system. NOOBS (New Out Of Box Software) is an easy operating system install manager for the Raspberry Pi. Buy preinstalled SD card First flight of Linux APM on Raspberry Pi 2 with Navio+ On the weekend we made the first flight of Linux APM on Raspberry Pi 2 with Navio+. Raspberry Pi 2 is a new quad-core version of the most popular single board computer in the world. It was clear that APM would benefit from higher processing power and as Raspberry Pi Foundation decided to stick to the HAT standard for their boards, Navio+ fits and works perfectly without any hardware modifications. How does it compare to the good old Model A+/B+? According to the benchmarks made by David Hunt RPi2 gave us about 7 times higher performance.
