Mobile Raspberry Pi Computer: Build your own portable Pi-to-Go

Mobile Raspberry Pi Computer: Build your own portable Pi-to-Go
Aw, yes, the Raspberry Pi Computer, a credit card size mini PC that only cost $35. There are so many possibilities and uses for these small nano PCs. People have made them into PVRs (personal video recorders), retro gaming machines, weather stations, in-car PCs, jukeboxes, and so many more creative ideas. When I started this project four weeks ago, I just wanted to see if it was possible to make an ultra portable, mobile Raspberry Pi that you can take to-go. My mobile Raspberry Pi Computer is now complete and because this is an open source project I wanted to show you everything, including how to build one yourself. Just a quick blurb about myself. LCD Screen The LCD I used is from an after market backup camera system that can be installed in a car. Battery Pack First off, be very careful when messing with lithium-ion batteries. Charging the battery was easy, I just purchased an after market laptop battery charger. Internal Powered Hub Extended Storage 64GB SSD, yes I did! Operating System Related:  Raspberry PiRaspberry PI

Raspberry Pi: Up and Running For those of you who haven’t yet played around with Raspberry Pi, this one’s for you. In this how-to video, I walk you through how to get a Raspberry Pi up and running. It’s the first in a series of Raspberry Pi videos that I’m making to accompany Getting Started with Raspberry Pi, a book I wrote with Shawn Wallace. If you’re intrigued by what you see but don’t yet have a Raspberry Pi, check out the Raspberry Pi Starter Kit in the Maker Shed. Keep an eye out for more Raspberry Pi videos in the coming months and leave a comment if there’s any particular material that you’d like to see covered in a MAKE video. Subscribe to How-Tos with Matt Richardson in iTunes, download the m4v video directly, or watch it on YouTube.

Download & Setup OctoPrint is currently available in the following forms: as part of a specialized distribution for the RaspberryPi called “OctoPi” as a source package A binary package for Debian-based Linux-systems is currently in the works. Guy Sheffer maintains “OctoPi”, an SD card image for the Raspberry Pi that already includes OctoPrint plus everything you need to run it: You can download the most current version from one of the following mirrors: The source is available here. Thomas Sanladerer created a great video guide on how to get OctoPi up an running: After flashing the image to SD and booting your RaspberryPi with it (if you don’t know how to do that take a look at these instructions which apply here as well), it should be available at – if you are running Windows, you will need to install “Bonjour for Windows” first for this to work (also see this FAQ entry with some more details on this) – or alternatively at its regular IP. The generic setup instructions boil down to Linux

Quick start guide What you will need Required SD CardWe recommend an 8GB class 4 SD card – ideally preinstalled with NOOBS. You can buy a card with NOOBS pre-installed, or you can download it for free from our downloads page.Display and connectivity cablesAny HDMI/DVI monitor or TV should work as a display for the Pi . For best results, use one with HDMI input, but other connections are available for older devices. Not essential but helpful to have Internet connectionTo update or download software, we recommend that you connect your Raspberry Pi to the internet either via and ethernet cable or a wifi adapter.HeadphonesHeadphones or earphones with a 3.5mm jack will work with your Raspberry Pi. Plugging in your Raspberry Pi Before you plug anything into your Raspberry Pi, make sure that you have all the equipment listed above to hand. Logging into your Raspberry Pi Once your Raspberry Pi has completed the boot process, a login prompt will appear. Read more in our documentation.

Contrôler son bureau à distance avec VNC sur le Raspberry pi Dans cet article nous allons voir comment télécommander son Raspberry pi à distance grâce à VNC (Virtual Network Connection), pour que cela fonctionne il faut que vous ayez suivi le tutoriel sur SSH et donc que vous puissiez vous connecter en SSH à votre Raspberry pi. La différence entre SSH et VNC est que SSH ne gère pas d’interface graphique il ne vous permet que d’exécuter des commandes dans le terminal, contrairement à VNC qui va vous donner la possibilité de contrôler votre Raspberry pi de manière graphique avec la souris et le clavier. Nous allons donc commencer par installer un serveur VNC, il en existe plusieurs, mais celui que je vous propose est tightvnc. Pour l’installer connecter vous en SSH au Raspberry pi et faites ces deux commandes sudo apt-get update sudo apt-get install tightvncserver Une fois que tightvnc est installé il faudra faire la commande vncserver :1 Si vous recevez un message d’avertissement cliquer sur continuer. Le bureau de votre Raspberry pi devrait apparaitre.

Pi NXT Robot Inspired by the amazing things the Boreatton Scouts group are doing with their Raspberry Pis, as well as a conversation with David Lamb and Andrew Attwood – two colleagues of mine at LJMU – I thought it was about time I actually tried to use my Pi for something other than recompiling existing software. I'm not a hardware person. Not at all. But after reading about how it's possible to control the NXT brick with Python using nxt-python, and with David pointing out how manifestly great it would be to get the first year undergraduates learning programming using it, I couldn't resist giving it a go. It turned out to be surprisingly easy. I'm not exactly sure why I bought such a huge lead given I knew it would all end up on top of the robot, but that's planning for you! The result really is as crazy and great as I'd hoped. It was also possible to read data from the sensors, allowing the robot to drive itself entirely autonomously around the room avoiding objects and generally exploring.

untitled 8 great Raspberry Pi projects created by kids What do you get when you combine the Raspberry Pi with some inspirational young inventors? Terrific Raspberry Pi project designs, that's what. Fourteen groups of teams from schools, universities and businesses gathered in late March at PA Consulting Group's Cambridge Technology Centre for the awards ceremony of the PA and Raspberry Pi-making competition. The young programmers presented their inventions to a hand-picked judging panel after being given three months to work on their designs, a £25 Raspberry Pi and up to £50 of additional hardware and software. The idea was that the inventions should be beneficial to others – perhaps enabling better healthcare delivery, promoting information or benefiting the environment. The competition was launched in response to a fall in programming skills and was aimed at increasing the numbers of skilled coders, developers and engineers. So without further ado, let's check out some of the projects put together by the teams: 1. This school loves running.

Getting Started With The Raspberry Pi Is Not As Easy As Pie The super low cost computer called the Raspberry Pi is mind-blowing and awesome. As TechCrunch recently reported, the $25 to $35 mini computer on a circuit board is designed to give kids around the globe an easy way to learn computer programming. But the Raspberry Pi is not like a computer you get from Apple or pickup at the local Best Buy. It’s not as simple as plug and play. I got my hands on one of the 400,000 units that have been sold. While a $25 to $35 computer makes a nice headline, the odds are good it’s going to cost you several times that amount to get it going. You will need to connect a power supply, monitor, USB keyboard, mouse, SD memory card, and an Ethernet connection. Diagram by Paul Beech and via website The distributors selling the Raspberry Pi also sell some of the needed accessories, but they are in high demand and short supply, just like the circuit board itself. Power I started by searching for a power source as no power cable is included. Monitor

Raspberry Pi Model B+ – Raspberry Pi Projects Using Model B SD Cards On The Model B+ SD cards should be interchangeable between a model B and a model B+ as long as the card was created since the release of the Model B+, or has been inserted into a model B since the B+ was released and these commands entered to update the OS and any other packages supported by apt-get: sudo apt-get update […] Read More → Model B+ Power RPi Power Consumption Varies depending on how busy it is and what peripherals are connected. Running a GUI and running the GPU will take extra power. Model B+ IO Pins Note that we are not currently sure if the new pin 27-40 PWM1, GPCLK1 and GPCLK2 peripheral pin functions will be made accessible under Raspbian and if so which pins they will be assigned to, hence the duplicated pins shown with these functions. Model B+ schematics The model B+ schematic is available from here. Model B+ CAD & Mounting Info The Raspberry Pi PCB measures 85mm x 56.2mm excluding overhanging connectors and is 20.8mm high.
