Mince Pi – what’s under your tree?

Post Syndicated from Liz Upton original https://www.raspberrypi.org/blog/mince-pi-whats-under-your-tree/

Merry Christmas everybody! We’re taking a little time off to spend with our families; we’ll be back in 2019. This post is for those of you who have found a piece of Pi under the tree or nestling uncomfortably in the toe of a stocking, and who are wondering what to do with it. Raise a glass of egg nog and join us in fighting over who gets the crispy bits this lunchtime.

So you’re the proud owner of a brand-new Raspberry Pi. Now what?

Your new Raspberry Pi

Did you wake up this morning to find a new Raspberry Pi under the tree? Congratulations, and welcome to the Raspberry Pi community! You’re one of us now, and we’re happy to have you on board.

But what if you’ve never seen a Raspberry Pi before? What are you supposed to do with it? What’s all the fuss about, and why does your new computer look so naked?

Setting up your Raspberry Pi

Are you comfy? Good. Then let us begin.

Download our free operating system

First of all, you need to make sure you have an operating system on your micro SD card: we suggest Raspbian, the Raspberry Pi Foundation’s official supported operating system. If your Pi is part of a starter kit, you might find that it comes with a micro SD card that already has Raspbian preinstalled. If not, you can download Raspbian for free from our website.

An easy way to get Raspbian onto your SD card is to use a free tool called Etcher. Watch The MagPi’s Lucy Hattersley show you what you need to do. You can also use NOOBS to install Raspbian on your SD card, and our Getting Started guide explains how to do that.

Plug it in and turn it on

Your new Raspberry Pi 3 comes with four USB ports and an HDMI port. These allow you to plug in a keyboard, a mouse, and a television or monitor. If you have a Raspberry Pi Zero, you may need adapters to connect your devices to its micro USB and micro HDMI ports. Both the Raspberry Pi 3 and the Raspberry Pi Zero W have onboard wireless LAN, so you can connect to your home network, and you can also plug an Ethernet cable into the Pi 3.

Make sure to plug the power cable in last. There’s no ‘on’ switch, so your Pi will turn on as soon as you connect the power. Raspberry Pi uses a micro USB power supply, so you can use a phone charger if you didn’t receive one as part of a kit.

Learn with our free projects

If you’ve never used a Raspberry Pi before, or you’re new to the world of coding, the best place to start is our projects site. It’s packed with free projects that will guide you through the basics of coding and digital making. You can create projects right on your screen using Scratch and Python, connect a speaker to make music with Sonic Pi, and upgrade your skills to physical making using items from around your house.

Here’s James to show you how to build a whoopee cushion using a Raspberry Pi, paper plates, tin foil and a sponge:

Explore the world of Raspberry Pi physical computing with our free FutureLearn courses: http://rpf.io/futurelearn.

Diving deeper

You’ve plundered our projects, you’ve successfully rigged every chair in the house to make rude noises, and now you want to dive deeper into digital making. Good! While you’re digesting your Christmas dinner, take a moment to skim through the Raspberry Pi blog for inspiration. You’ll find projects from across our worldwide community, with everything from home automation projects and retrofit upgrades, to robots, gaming systems, and cameras.

Need a beginners’ guidebook? Look no further: here’s the official guide. It’s also available as a free download, like all our publications.

You’ll also find bucketloads of ideas in The MagPi magazine, the official monthly Raspberry Pi publication, available in both print and digital format. You can download every issue for free. If you subscribe, you’ll get a free Raspberry Pi 3A+ to add to your new collection. HackSpace magazine is another fantastic place to turn for Raspberry Pi projects, along with other maker projects and tutorials.

And, of course, simply typing “Raspberry Pi projects” into your preferred search engine will find thousands of ideas. Sites like Hackster, Hackaday, Instructables, Pimoroni, and Adafruit all have plenty of fab Raspberry Pi tutorials that they’ve devised themselves and that community members like you have created.

And finally

If you make something marvellous with your new Raspberry Pi – and we know you will – don’t forget to share it with us! Our Twitter, Facebook and Instagram accounts are brimming with chatter, projects, and events. And our forums are the best place to visit if you ever have questions about your Raspberry Pi or if you need some help.

It’s good to get together with like-minded folks, so check out the growing Raspberry Jam movement. Raspberry Jams are community-run events where makers and enthusiasts can meet other makers, show off their projects, and join in with workshops and discussions. Find your nearest Jam here.

Have a great break, and welcome to the community. We’ll see you in 2019!

Christmas lights 2018

Post Syndicated from Liz Upton original https://www.raspberrypi.org/blog/christmas-lights-2018/

It’s the most wonderful time of the year! There’s much mistletoeing, and hearts will be glowing – as will thousands of Raspberry Pi-enabled Christmas light displays around the world.

Polish roadside crib

This morning I have mostly been spending my virtual time by a roadside in snowy Poland, inflicting carols on passers-by. (It turns out that the Polish carols this crib is programmed with rock a lot harder than the ones we listen to in England.) Visit the crib’s website to control it yourself.

Helpfully, Tomek, the maker, has documented some of the build over on Hackster if you want to learn more.

LightShow Pi

We are also suckers for a good Christmas son et lumiere. If you’re looking to make something yourself, LightShow Pi has been around for some years now, and goes from strength to strength. We’ve covered projects built with it in previous years, and it’s still in active development from what we can see, with new features for this Christmas like the ability to address individual RGB pixels. Most of the sound and music displays you’ll see using a Raspberry Pi are running LightShow Pi; it’s got a huge user base, and its online community on Reddit is a great place to get started.

2018 Christmas Light Show

Light display contains over 4,000 lights and 7,800 individual channels. It is controlled by 3 network based lighting controllers. The audio and lighting sequences are sent to the controllers by a Raspberry Pi.

This display from the USA must have taken forever to set up: you’re looking at 4,000 lights and 7,800 channels.  Here’s something more domestically proportioned from YouTube user Ken B, showing off LightShow Pi’s microweb user interface, which is perfect for use on your phone.

LightShow Pi Christmas Tree 2018

Scared of the neighbours burning down your outdoor display, or not enough space for a full-size tree? Never fear: The Pi Hut’s 3D Christmas tree, designed by Rachel Rayns, formerly of this parish, is on sale again this year. We particularly loved this adaptation from Blitz City DIY, where Liz (not me, another Liz) RGB-ifies the tree: a great little Christmas electronics project to work through with the kids. Or on your own, because we don’t need to have all our fun vicariously through our children this Christmas. (Repeat ten times.)

RGB-ing the Pi Hut Xmas Tree Kit

The Pi Hut’s Xmas Tree Kit is a fun little soldering kit for the Raspberry Pi. It’s a great kit, but I thought it could do with a bit more color. This is just a quick video to talk about the kit and show off all the RGB goodness.

Minecraft-controlled real world Christmas tree

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/minecraft-controlled-christmas-tree/

Interact with the real world via the block world, with the Minecraft-controlled Christmas tree from the team at BroCraft Gaming.

Illuminating

David Stevens of BroCraft Gaming reached out to us last month to let us know about the real-life Christmas tree he and his team were planning to hack using Minecraft. Intriguing? Obviously. And after a few more emails, David has been back in touch to let us know the tree hack is now live and ready for the world to interact with.

Here’s a blurb from the BroCraft team:

Join our Minecraft server at brocraftlive.net, complete the tutorial if you haven’t already, and type /mcct to join our snowy wonderland. Collect power from power blocks dotted everywhere, then select a pattern with the Technician, and watch as the tree lights up on the camera stream LIVE before your very eyes! Visit the attractions, play our minigames, and find out what else our server has to offer.

The tree uses individually addressable LEDs and the Adafruit Neopixel Python library. And with the help of a bespoke Java plugin, all instructions from within the Minecraft server are fed to the lights via a Raspberry Pi.

You can view the live Christmas tree camera stream here, along with a brief FAQ on interacting with the tree within the BroCraft Minecraft server.

Minecraft Pi

You’ll need access to Minecraft to be able to interact with the tree. And, lucky for you, Minecraft Pi comes free with Raspbian on the Raspberry Pi!

To flash the Raspbian image onto an SD card, follow this video tutorial from the team at The MagPi. And to get more acquainted with Minecraft on the Raspberry Pi, check out our free resources, including the getting started guide, Minecraft selfies, and the big Minecraft piano.



Find more free Raspberry Pi resources on our projects site, and immerse yourself even further into the world of Minecraft Pi with The MagPi’s Hacking and Making in Minecraft Essentials Guide, available in print and as a free PDF download!

The Raspberry Pi Christmas shopping list 2018

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/christmas-shopping-list-2018/

Looking for this year’s perfect something to put under the tree ‘from Santa’? Well, look no further than right here — it’s time for our traditional Christmas shopping list!

Woohoo!

Which Raspberry Pi?

As you are no doubt aware, the Raspberry Pi comes in more than one variety. And if you’re planning to give a Pi as a gift to a first-time user, you may be confused as to which one you should buy.

Raspberry Pi 3B+

For someone learning to write code for the first time, we recommend the Raspberry Pi 3B+. Anyone living in a home with an HDMI display, such as a computer monitor or television, will be able to plug directly into the 3B+, and in case they don’t already have a standard USB mouse and keyboard, these can both easily be acquired online, in many charity shops, or by sweet-talking a friend/neighbour/employer. You can even find some great Raspberry Pi starter kits that include many of the items needed to get started.

Raspberry Pi Zero W

The Raspberry Pi Zero W comes at a lower price, and with it, a smaller footprint than the 3B+. This makes the tiny Pi the perfect addition to any creator’s toolkit, ideal for projects that run on a Pi long-term, such as display builds, robots, or near-space HABs.

Pre-loaded micro SD card

Whatever Raspberry Pi you choose for the lucky receiver of your Christmas gift, we also recommend getting them a pre-loaded micro SD card. While it’s really easy to flash an operating system image onto one of the dusty old micro SD cards you have lurking in a drawer, pre-loaded cards allow new Pi owners to plug in and get started right off the bat. Plus, the ones with our operating system Raspbian on come in rather fancy, logo-adorned SD adapters. And who doesn’t like a rather fancy, logo-adorned SD adapter?

Books, books, books

We’re releasing two new books this week that are perfect for any Christmas stocking!

Code Club Book of Scratch Volume 1

Code Club Book of Scratch Volume 1

The Code Club team is buzzing over the release of the first Code Club book, available to buy from Friday. Primarily aimed at learners aged 9–13, the book focuses on teaching the Scratch programming language, and it’s jam-packed with fun projects, tips, and stickers. The book also comes with a pair of super-special computer science glasses that allow you to see secret hints hidden throughout the book. Very, very cool.

And since Scratch is pre-installed on Raspbian, the Code Club Book of Scratch is the perfect accompaniment to that Raspberry Pi you’re planning to get for the young person in your life!

The Official Raspberry Pi Beginner’s Guide

Raspberry Pi Beginner's Guide Book 2018

From setting up a Raspberry Pi to using Scratch and Python to create games and animations, the hot-off-the-press Official Raspberry Pi Beginner’s Guide has everything your loved one needs to get started and keep going.

And when we say ‘ hot-off-the-press’, we mean it — we only released the book this week!

Both the Raspberry Pi Beginner’s Guide and the Code Club Book of Scratch are available with free international shipping. And if you’d like to give either of them a ‘try before you buy’ test drive, they should both available soon as free PDFs for you to download and peruse at your leisure.

Magazine subscriptions

Alongside our books, we have an array of magazines, including the brand-new, twice-monthly, video game–focused Wireframe! As with the books, you can download all issues of our magazines for a test read before you commit to a subscription.

Twelve-month print subscriptions to HackSpace magazine or The MagPi will reward you with a technical treat: an Adafruit Circuit Playground or a Raspberry Pi 3A+.


So not only can you give a gift that will last the entirety of 2019, but you’ll also automatically provide your favourite creative person with something rather lovely to play with when they receive their first issue.

And if you sign them up now, you can give someone a six-issue subscription of Wireframe magazine for £12! Or save 49% on a twelve-month subscription of 26 magazines from £40.

So many choices, so many ways to make the creators and tech fans in your life happy this holiday season.

Accessories and such

Maybe the person you’re shopping for already has every Raspberry Pi on the market. And as for our publications, their mailbox is full of magazines and books every week, and their smartphone and tablets are crammed with every PDF we’ve ever produced. So what next?

Swag

What do you buy the Raspberry Pi fan who has all the Pis? Swag, of course!

Raspberry Pi Swag - enamel pin
Raspberry Pi Swag - travel card holder
Raspberry Pi Swag - Mug

From stickers and mugs, to coasters and pins, check out the Raspberry Pi swag store for some wonderful treats!

Add-ons

Whether it’s a HAT (Hardware Attached on Top) for the Raspberry Pi, or a full kit to make something rather spectacular, our Approved Resellers stock all manner of Pi add-ons.


Pimoroni Picade
Pi Hut LED Xmas Tree

You can find your nearest Raspberry Pi Approved Reseller by clicking on any item on our products page and then selecting your country.

This isn’t all!

We’ve been putting together a Raspberry Pi shopping list every year in response to the message we receive from you asking for gift ideas. So why not have a look back at our previous lists to get more inspiration for what to give, including more books, toolkit staples, non-Pi tech bits, and, of course, LEGO.

Happy birthday to us!

Post Syndicated from Eben Upton original https://www.raspberrypi.org/blog/happy-birthday-2018/

The eagle-eyed among you may have noticed that today is 28 February, which is as close as you’re going to get to our sixth birthday, given that we launched on a leap day. For the last three years, we’ve launched products on or around our birthday: Raspberry Pi 2 in 2015; Raspberry Pi 3 in 2016; and Raspberry Pi Zero W in 2017. But today is a snow day here at Pi Towers, so rather than launching something, we’re taking a photo tour of the last six years of Raspberry Pi products before we don our party hats for the Raspberry Jam Big Birthday Weekend this Saturday and Sunday.

Prehistory

Before there was Raspberry Pi, there was the Broadcom BCM2763 ‘micro DB’, designed, as it happens, by our very own Roger Thornton. This was the first thing we demoed as a Raspberry Pi in May 2011, shown here running an ARMv6 build of Ubuntu 9.04.

BCM2763 micro DB

Ubuntu on Raspberry Pi, 2011-style

A few months later, along came the first batch of 50 “alpha boards”, designed for us by Broadcom. I used to have a spreadsheet that told me where in the world each one of these lived. These are the first “real” Raspberry Pis, built around the BCM2835 application processor and LAN9512 USB hub and Ethernet adapter; remarkably, a software image taken from the download page today will still run on them.

Raspberry Pi alpha board, top view

We shot some great demos with this board, including this video of Quake III:

Raspberry Pi – Quake 3 demo

A little something for the weekend: here’s Eben showing the Raspberry Pi running Quake 3, and chatting a bit about the performance of the board. Thanks to Rob Bishop and Dave Emett for getting the demo running.

Pete spent the second half of 2011 turning the alpha board into a shippable product, and just before Christmas we produced the first 20 “beta boards”, 10 of which were sold at auction, raising over £10000 for the Foundation.

The beginnings of a Bramble

Beta boards on parade

Here’s Dom, demoing both the board and his excellent taste in movie trailers:

Raspberry Pi Beta Board Bring up

See http://www.raspberrypi.org/ for more details, FAQ and forum.

Launch

Rather to Pete’s surprise, I took his beta board design (with a manually-added polygon in the Gerbers taking the place of Paul Grant’s infamous red wire), and ordered 2000 units from Egoman in China. After a few hiccups, units started to arrive in Cambridge, and on 29 February 2012, Raspberry Pi went on sale for the first time via our partners element14 and RS Components.

Unboxing continues

The first Raspberry Pi from the first box from the first pallet

We took over 100000 orders on the first day: something of a shock for an organisation that had imagined in its wildest dreams that it might see lifetime sales of 10000 units. Some people who ordered that day had to wait until the summer to finally receive their units.

Evolution

Even as we struggled to catch up with demand, we were working on ways to improve the design. We quickly replaced the USB polyfuses in the top right-hand corner of the board with zero-ohm links to reduce IR drop. If you have a board with polyfuses, it’s a real limited edition; even more so if it also has Hynix memory. Pete’s “rev 2” design made this change permanent, tweaked the GPIO pin-out, and added one much-requested feature: mounting holes.

Revision 1 versus revision 2

If you look carefully, you’ll notice something else about the revision 2 board: it’s made in the UK. 2012 marked the start of our relationship with the Sony UK Technology Centre in Pencoed, South Wales. In the five years since, they’ve built every product we offer, including more than 12 million “big” Raspberry Pis and more than one million Zeros.

Celebrating 500,000 Welsh units, back when that seemed like a lot

Economies of scale, and the decline in the price of SDRAM, allowed us to double the memory capacity of the Model B to 512MB in the autumn of 2012. And as supply of Model B finally caught up with demand, we were able to launch the Model A, delivering on our original promise of a $25 computer.

A UK-built Raspberry Pi Model A

In 2014, James took all the lessons we’d learned from two-and-a-bit years in the market, and designed the Model B+, and its baby brother the Model A+. The Model B+ established the form factor for all our future products, with a 40-pin extended GPIO connector, four USB ports, and four mounting holes.

The Raspberry Pi 1 Model B+ — entering the era of proper product photography with a bang.

New toys

While James was working on the Model B+, Broadcom was busy behind the scenes developing a follow-on to the BCM2835 application processor. BCM2836 samples arrived in Cambridge at 18:00 one evening in April 2014 (chips never arrive at 09:00 — it’s always early evening, usually just before a public holiday), and within a few hours Dom had Raspbian, and the usual set of VideoCore multimedia demos, up and running.

We launched Raspberry Pi 2 at the start of 2015, pairing BCM2836 with 1GB of memory. With a quad-core Arm Cortex-A7 clocked at 900MHz, we’d increased performance sixfold, and memory fourfold, in just three years.

Nobody mention the xenon death flash.

And of course, while James was working on Raspberry Pi 2, Broadcom was developing BCM2837, with a quad-core 64-bit Arm Cortex-A53 clocked at 1.2GHz. Raspberry Pi 3 launched barely a year after Raspberry Pi 2, providing a further doubling of performance and, for the first time, wireless LAN and Bluetooth.

All our recent products are just the same board shot from different angles

Zero to hero

Where the PC industry has historically used Moore’s Law to “fill up” a given price point with more performance each year, the original Raspberry Pi used Moore’s law to deliver early-2000s PC performance at a lower price. But with Raspberry Pi 2 and 3, we’d gone back to filling up our original $35 price point. After the launch of Raspberry Pi 2, we started to wonder whether we could pull the same trick again, taking the original Raspberry Pi platform to a radically lower price point.

The result was Raspberry Pi Zero. Priced at just $5, with a 1GHz BCM2835 and 512MB of RAM, it was cheap enough to bundle on the front of The MagPi, making us the first computer magazine to give away a computer as a cover gift.

Cheap thrills

MagPi issue 40 in all its glory

We followed up with the $10 Raspberry Pi Zero W, launched exactly a year ago. This adds the wireless LAN and Bluetooth functionality from Raspberry Pi 3, using a rather improbable-looking PCB antenna designed by our buddies at Proant in Sweden.

Up to our old tricks again

Other things

Of course, this isn’t all. There has been a veritable blizzard of point releases; RAM changes; Chinese red units; promotional blue units; Brazilian blue-ish units; not to mention two Camera Modules, in two flavours each; a touchscreen; the Sense HAT (now aboard the ISS); three compute modules; and cases for the Raspberry Pi 3 and the Zero (the former just won a Design Effectiveness Award from the DBA). And on top of that, we publish three magazines (The MagPi, Hello World, and HackSpace magazine) and a whole host of Project Books and Essentials Guides.

Forward the Foundation

Why does all this matter? Because we’re providing everyone, everywhere, with the chance to own a general-purpose programmable computer for the price of a cup of coffee; because we’re giving people access to tools to let them learn new skills, build businesses, and bring their ideas to life; and because when you buy a Raspberry Pi product, every penny of profit goes to support the Raspberry Pi Foundation in its mission to change the face of computing education.

We’ve had an amazing six years, and they’ve been amazing in large part because of the community that’s grown up alongside us. This weekend, more than 150 Raspberry Jams will take place around the world, comprising the Raspberry Jam Big Birthday Weekend.

Community Profile: Estefannie Explains It All

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/community-profile-estefannie/

This column is from The MagPi issue 59. You can download a PDF of the full issue for free, or subscribe to receive the print edition through your letterbox or the digital edition on your tablet. All proceeds from the print and digital editions help the Raspberry Pi Foundation achieve our charitable goals.

“Hey, world!” Estefannie exclaims, a wide grin across her face as the camera begins to roll for another YouTube tutorial video. With a growing number of followers and wonderful support from her fans, Estefannie is building a solid reputation as an online maker, creating unique, fun content accessible to all.

A woman sitting at a desk with a laptop and papers — Estefannie Explains it All Raspberry Pi

It’s as if she was born into performing and making for an audience, but this fun, enjoyable journey to social media stardom came not from a desire to be in front of the camera, but rather as a unique approach to her own learning. While studying, Estefannie decided the best way to confirm her knowledge of a subject was to create an educational video explaining it. If she could teach a topic successfully, she knew she’d retained the information. And so her YouTube channel, Estefannie Explains It All, came into being.

Note taking — Estefannie Explains it All

Her first videos featured pages of notes with voice-over explanations of data structure and algorithm analysis. Then she moved in front of the camera, and expanded her skills in the process.

But YouTube isn’t her only outlet. With nearly 50000 followers, Estefannie’s Instagram game is strong, adding to an increasing number of female coders taking to the platform. Across her Instagram grid, you’ll find insights into her daily routine, from programming on location for work to behind-the-scenes troubleshooting as she begins to create another tutorial video. It’s hard work, with content creation for both Instagram and YouTube forever on her mind as she continues to work and progress successfully as a software engineer.

A woman showing off a game on a tablet — Estefannie Explains it All Raspberry Pi

As a thank you to her Instagram fans for helping her reach 10000 followers, Estefannie created a free game for Android and iOS called Gravitris — imagine Tetris with balance issues!

Estefannie was born and raised in Mexico, with ambitions to become a graphic designer and animator. However, a documentary on coding at Pixar, and the beauty of Merida’s hair in Brave, opened her mind to the opportunities of software engineering in animation. She altered her career path, moved to the United States, and switched to a Computer Science course.

A woman wearing safety goggles hugging a keyboard Estefannie Explains it All Raspberry Pi

With a constant desire to make and to learn, Estefannie combines her software engineering profession with her hobby to create fun, exciting content for YouTube.

While studying, Estefannie started a Computer Science Girls Club at the University of Houston, Texas, and she found herself eager to put more time and effort into the movement to increase the percentage of women in the industry. The club was a success, and still is to this day. While Estefannie has handed over the reins, she’s still very involved in the cause.

Through her YouTube videos, Estefannie continues the theme of inclusion, with every project offering a warm sense of approachability for all, regardless of age, gender, or skill. From exploring Scratch and Makey Makey with her young niece and nephew to creating her own Disney ‘Made with Magic’ backpack for a trip to Disney World, Florida, Estefannie’s videos are essentially a documentary of her own learning process, produced so viewers can learn with her — and learn from her mistakes — to create their own tech wonders.

Using the Raspberry Pi, she’s been able to broaden her skills and, in turn, her projects, creating a home-automated gingerbread house at Christmas, building a GPS-controlled GoPro for her trip to London, and making everyone’s life better with an Internet Button–controlled French press.

Estefannie Explains it All Raspberry Pi Home Automated Gingerbread House

Estefannie’s automated gingerbread house project was a labour of love, with electronics, wires, and candy strewn across both her living room and kitchen for weeks before completion. While she already was a skilled programmer, the world of physical digital making was still fairly new for Estefannie. Having ditched her hot glue gun in favour of a soldering iron in a previous video, she continued to experiment and try out new, interesting techniques that are now second nature to many members of the maker community. With the gingerbread house, Estefannie was able to research and apply techniques such as light controls, servos, and app making, although the latter was already firmly within her skill set. The result? A fun video of ups and downs that resulted in a wonderful, festive treat. She even gave her holiday home its own solar panel!

And that’s just the beginning of her adventures with Pi…but we won’t spoil her future plans by telling you what’s coming next. Sorry! However, since this article was written last year, Estefannie has released a few more Pi-based project videos, plus some awesome interviews and live-streams with other members of the maker community such as Simone Giertz. She even made us an awesome video for our Raspberry Pi YouTube channel! So be sure to check out her latest releases.

Best day yet!! I got to hangout, play Jenga with a huge arm robot, and have afternoon tea with @simonegiertz and robots!! 🤖👯 #shittyrobotnation

A hedgehog cam or two

Post Syndicated from Helen Lynn original https://www.raspberrypi.org/blog/a-hedgehog-cam-or-two/

Here we are, hauling ourselves out of the Christmas and New Year holidays and into January proper. It’s dawning on me that I have to go back to work, even though it’s still very cold and gloomy in northern Europe, and even though my duvet is lovely and warm. I found myself envying beings that hibernate, and thinking about beings that hibernate, and searching for things to do with hedgehogs. And, well, the long and the short of it is, today’s blog post is a short meditation on the hedgehog cam.

Hedgehog watching

Someone called Barker has installed a Raspberry Pi–based hedgehog cam in a location with a distant view of a famous Alp, and as well as providing live views by visible and infrared light for the dedicated and the insomniac, they also make a sped-up version of the previous night’s activity available. With hedgehogs usually being in hibernation during January, you mightn’t see them in any current feed — but don’t worry! You’re guaranteed a few hedgehogs on Barker’s website, because they have also thrown in some lovely GIFs of hoggy (and foxy) divas that their camera captured in the past.

Build your own hedgehog cam

For pointers on how to replicate this kind of setup, you could do worse than turn to Andrew Wedgbury’s hedgehog cam write-up. Andrew’s Twitter feed reveals that he’s a Cambridge local, and there are hints that he was behind RealVNC’s hoggy mascot for Pi Wars 2017.

RealVNC on Twitter

Another day at the office: testing our #PiWars mascot using a @Raspberry_Pi 3, #VNC Connect and @4tronix_uk Picon Zero. Name suggestions? https://t.co/iYY3xAX9Bk

Our infrared bird box and time-lapse camera resources will also set you well on the way towards your own custom wildlife camera. For a kit that wraps everything up in a weatherproof enclosure made with love, time, and serious amounts of design and testing, take a look at Naturebytes’ wildlife cam kit.

Or, if you’re thinking that a robot mascot is more dependable than real animals for the fluffiness you need in order to start your January with something like productivity and with your soul intact, you might like to put your own spin on our robot buggy.

Happy 2018

While we’re on the subject of getting to grips with the new year, do take a look at yesterday’s blog post, in which we suggest a New Year’s project that’s different from the usual resolutions. However you tackle 2018, we wish you an excellent year of creative computing.

Reka makes a “decorative Santa cam,” meaning that it’s not a real camera. Instead, it just gets children used to being under constant surveillance.

Our Santa Cam has a cute Father Christmas and mistletoe design, and a red, flashing LED light which will make the most logical kids suspend their disbelief and start to believe!

Thank you for my new Raspberry Pi, Santa! What next?

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/thank-you-for-my-new-raspberry-pi-santa-what-next/

Note: the Pi Towers team have peeled away from their desks to spend time with their families over the festive season, and this blog will be quiet for a while as a result. We’ll be back in the New Year with a bushel of amazing projects, awesome resources, and much merriment and fun times. Happy holidays to all!

Now back to the matter at hand. Your brand new Christmas Raspberry Pi.

Your new Raspberry Pi

Did you wake up this morning to find a new Raspberry Pi under the tree? Congratulations, and welcome to the Raspberry Pi community! You’re one of us now, and we’re happy to have you on board.

But what if you’ve never seen a Raspberry Pi before? What are you supposed to do with it? What’s all the fuss about, and why does your new computer look so naked?

Setting up your Raspberry Pi

Are you comfy? Good. Then let us begin.

Download our free operating system

First of all, you need to make sure you have an operating system on your micro SD card: we suggest Raspbian, the Raspberry Pi Foundation’s official supported operating system. If your Pi is part of a starter kit, you might find that it comes with a micro SD card that already has Raspbian preinstalled. If not, you can download Raspbian for free from our website.

An easy way to get Raspbian onto your SD card is to use a free tool called Etcher. Watch The MagPi’s Lucy Hattersley show you what you need to do. You can also use NOOBS to install Raspbian on your SD card, and our Getting Started guide explains how to do that.

Plug it in and turn it on

Your new Raspberry Pi 3 comes with four USB ports and an HDMI port. These allow you to plug in a keyboard, a mouse, and a television or monitor. If you have a Raspberry Pi Zero, you may need adapters to connect your devices to its micro USB and micro HDMI ports. Both the Raspberry Pi 3 and the Raspberry Pi Zero W have onboard wireless LAN, so you can connect to your home network, and you can also plug an Ethernet cable into the Pi 3.

Make sure to plug the power cable in last. There’s no ‘on’ switch, so your Pi will turn on as soon as you connect the power. Raspberry Pi uses a micro USB power supply, so you can use a phone charger if you didn’t receive one as part of a kit.

Learn with our free projects

If you’ve never used a Raspberry Pi before, or you’re new to the world of coding, the best place to start is our projects site. It’s packed with free projects that will guide you through the basics of coding and digital making. You can create projects right on your screen using Scratch and Python, connect a speaker to make music with Sonic Pi, and upgrade your skills to physical making using items from around your house.

Here’s James to show you how to build a whoopee cushion using a Raspberry Pi, paper plates, tin foil and a sponge:

Whoopee cushion PRANK with a Raspberry Pi: HOW-TO

Explore the world of Raspberry Pi physical computing with our free FutureLearn courses: http://rpf.io/futurelearn Free make your own Whoopi Cushion resource: http://rpf.io/whoopi For more information on Raspberry Pi and the charitable work of the Raspberry Pi Foundation, including Code Club and CoderDojo, visit http://rpf.io Our resources are free to use in schools, clubs, at home and at events.

Diving deeper

You’ve plundered our projects, you’ve successfully rigged every chair in the house to make rude noises, and now you want to dive deeper into digital making. Good! While you’re digesting your Christmas dinner, take a moment to skim through the Raspberry Pi blog for inspiration. You’ll find projects from across our worldwide community, with everything from home automation projects and retrofit upgrades, to robots, gaming systems, and cameras.

You’ll also find bucketloads of ideas in The MagPi magazine, the official monthly Raspberry Pi publication, available in both print and digital format. You can download every issue for free. If you subscribe, you’ll get a Raspberry Pi Zero W to add to your new collection. HackSpace magazine is another fantastic place to turn for Raspberry Pi projects, along with other maker projects and tutorials.

And, of course, simply typing “Raspberry Pi projects” into your preferred search engine will find thousands of ideas. Sites like Hackster, Hackaday, Instructables, Pimoroni, and Adafruit all have plenty of fab Raspberry Pi tutorials that they’ve devised themselves and that community members like you have created.

And finally

If you make something marvellous with your new Raspberry Pi – and we know you will – don’t forget to share it with us! Our Twitter, Facebook, Instagram and Google+ accounts are brimming with chatter, projects, and events. And our forums are a great place to visit if you have questions about your Raspberry Pi or if you need some help.

It’s good to get together with like-minded folks, so check out the growing Raspberry Jam movement. Raspberry Jams are community-run events where makers and enthusiasts can meet other makers, show off their projects, and join in with workshops and discussions. Find your nearest Jam here.

Have a great festive holiday and welcome to the community. We’ll see you in 2018!

The deep learning Santa/Not Santa detector

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/deep-learning-santa-detector/

Did you see Mommy kissing Santa Claus? Or was it simply an imposter? The Not Santa detector is here to help solve the mystery once and for all.

Building a “Not Santa” detector on the Raspberry Pi using deep learning, Keras, and Python

The video is a demo of my “Not Santa” detector that I deployed to the Raspberry Pi. I trained the detector using deep learning, Keras, and Python. You can find the full source code and tutorial here: https://www.pyimagesearch.com/2017/12/18/keras-deep-learning-raspberry-pi/

Ho-ho-how does it work?

Note: Adrian Rosebrock is not Santa. But he does a good enough impression of the jolly old fellow that his disguise can fool a Raspberry Pi into thinking otherwise.

Raspberry Pi 'Not Santa' detector

We jest, but has anyone seen Adrian and Santa in the same room together?
Image c/o Adrian Rosebrock

But how is the Raspberry Pi able to detect the Santa-ness or Not-Santa-ness of people who walk into the frame?

Two words: deep learning

If you’re not sure what deep learning is, you’re not alone. It’s a hefty topic, and one that Adrian has written a book about, so I grilled him for a bluffers’ guide. In his words, deep learning is:

…a subfield of machine learning, which is, in turn a subfield of artificial intelligence (AI). While AI embodies a large, diverse set of techniques and algorithms related to automatic reasoning (inference, planning, heuristics, etc), the machine learning subfields are specifically interested in pattern recognition and learning from data.

Artificial Neural Networks (ANNs) are a class of machine learning algorithms that can learn from data. We have been using ANNs successfully for over 60 years, but something special happened in the past 5 years — (1) we’ve been able to accumulate massive datasets, orders of magnitude larger than previous datasets, and (2) we have access to specialized hardware to train networks faster (i.e., GPUs).

Given these large datasets and specialized hardware, deeper neural networks can be trained, leading to the term “deep learning”.

So now we have a bird’s-eye view of deep learning, how does the detector detect?

Cameras and twinkly lights

Adrian used a model he had trained on two datasets to detect whether or not an image contains Santa. He deployed the Not Santa detector code to a Raspberry Pi, then attached a camera, speakers, and The Pi Hut’s 3D Xmas Tree.

Raspberry Pi 'Not Santa' detector

Components for Santa detection
Image c/o Adrian Rosebrock

The camera captures footage of Santa in the wild, while the Christmas tree add-on provides a twinkly notification, accompanied by a resonant ho, ho, ho from the speakers.

A deeper deep dive into deep learning

A full breakdown of the project and the workings of the Not Santa detector can be found on Adrian’s blog, PyImageSearch, which includes links to other deep learning and image classification tutorials using TensorFlow and Keras. It’s an excellent place to start if you’d like to understand more about deep learning.

Build your own Santa detector

Santa might catch on to Adrian’s clever detector and start avoiding the camera, and for that eventuality, we have our own Santa detector. It uses motion detection to notify you of his presence (and your presents!).

Check out our Santa Detector resource here and use a passive infrared sensor, Raspberry Pi, and Scratch to catch the big man in action.

Rosie the Countdown champion

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/rosie-the-countdown-champion/

Beating the contestants at Countdown: is it cheating if you happen to know every word in the English dictionary?

Rosie plays Countdown

Allow your robots to join in the fun this Christmas with a round of Channel 4’s Countdown. https://www.rosietheredrobot.com/2017/12/tea-minus-30.html

Rosie the Red Robot

First, a little bit of backstory. Challenged by his eldest daughter to build a robot, technology-loving Alan got to work building Rosie.

I became (unusually) determined. I wanted to show her what can be done… and the how can be learnt later. After all, there is nothing more exciting and encouraging than seeing technology come alive. Move. Groove. Quite literally.

Originally, Rosie had a Raspberry Pi 3 brain controlling ultrasonic sensors and motors via Python. From there, she has evolved into something much grander, and Alan has documented her upgrades on the Rosie the Red Robot blog. Using GPS trackers and a Raspberry Pi camera module, she became Rosie Patrol, a rolling, walking, interactive bot; then, with further upgrades, the Tea Minus 30 project came to be. Which brings us back to Countdown.

T(ea) minus 30

In case it hasn’t been a big part of your life up until now, Countdown is one of the longest running televisions shows in history, and occupies a special place in British culture. Contestants take turns to fill a board with nine randomly selected vowels and consonants, before battling the Countdown clock to find the longest word they can in the space of 30 seconds.

The Countdown Clock

I’ve had quite a few requests to show just the Countdown clock for use in school activities/own games etc., so here it is! Enjoy! It’s a brand new version too, using the 2010 Office package.

There’s a numbers round involving arithmetic, too – but for now, we’re going to focus on letters and words, because that’s where Rosie’s skills shine.

Using an online resource, Alan created a dataset of the ten thousand most common English words.

Rosie the Red Robot Raspberry Pi

Many words, listed in order of common-ness. Alan wrote a Python script to order them alphabetically and by length

Next, Alan wrote a Python script to select nine letters at random, then search the word list to find all the words that could be spelled using only these letters. He used the randint function to select letters from a pre-loaded alphabet, and introduced a requirement to include at least two vowels among the nine letters.

Rosie the Red Robot Raspberry Pi

Words that match the available letters are displayed on the screen.

Rosie the Red Robot Raspberry Pi

Putting it all together

With the basic game-play working, it was time to bring the project to life. For this, Alan used Rosie’s camera module, along with optical character recognition (OCR) and text-to-speech capabilities.

Rosie the Red Robot Raspberry Pi

Alan writes, “Here’s a very amateurish drawing to brainstorm our idea. Let’s call it a design as it makes it sound like we know what we’re doing.”

Alan’s script has Rosie take a photo of the TV screen during the Countdown letters round, then perform OCR using the Google Cloud Vision API to detect the nine letters contestants have to work with. Next, Rosie runs Alan’s code to check the letters against the ten-thousand-word dataset, converts text to speech with Python gTTS, and finally speaks her highest-scoring word via omxplayer.

You can follow the adventures of Rosie the Red Robot on her blog, or follow her on Twitter. And if you’d like to build your own Rosie, Alan has provided code and tutorials for his projects too. Thanks, Alan!

All the lights, all of the twinkly lights

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/all-of-the-lights/

Twinkly lights are to Christmas what pumpkins are to Halloween. And when you add a Raspberry Pi to your light show, the result instantly goes from “Meh, yeah.” to “OMG, wow!”

Here are some cool light-based Christmas projects to inspire you this weekend.

Raspberry Pi Christmas Lights

App-based light control

Christmas Tree Lights Demo

Project Code – https://github.com/eidolonFIRE/Christmas-Lights Raspberry Pi A+ ws2812b – https://smile.amazon.com/gp/product/B01H04YAIQ/ref=od_aui_detailpages00?ie=UTF8&psc=1 200w 5V supply – https://smile.amazon.com/gp/product/B01LZRIWZD/ref=od_aui_detailpages01?ie=UTF8&psc=1

In his Christmas lights project, Caleb Johnson uses an app as a control panel to switch between predefined displays. The full code is available on his GitHub, and it connects a Raspberry Pi A+ to a strip of programmable LEDs that change their pattern at the touch of a phone screen.

What’s great about this project, aside from the simplicity of its design, is the scope for extending it. Why not share the app with friends and family, allowing them to control your lights remotely? Or link the lights to social media so they are triggered by a specific hashtag, like in Alex Ellis’ #cheerlights project below.

Worldwide holiday #cheerlights

Holiday lights hack – 1$ Snowman + Raspberry Pi

Here we have a smart holiday light which will only run when it detects your presence in the room through a passive infrared PIR sensor. I’ve used hot glue for the fixings and an 8-LED NeoPixel strip connected to port 18.

Cheerlights, an online service created by Hans Scharler, allows makers to incorporate hashtag-controlled lighting into the projects. By tweeting the hashtag #cheerlights, followed by a colour, you can control a network of lights so that they are all displaying the same colour.

For his holiday light hack using Cheerlights, Alex incorporated the Pimoroni Blinkt! and a collection of cheap Christmas decorations to create cute light-up ornaments for the festive season.

To make your own, check out Alex’s blog post, and head to your local £1/$1 store for hackable decor. You could even link your Christmas tree and the trees of your family, syncing them all in one glorious, Santa-pleasing spectacular.

Outdoor decorations

DIY musical Xmas lights for beginners with raspberry pi

With just a few bucks of extra material, I walk you through converting your regular Christmas lights into a whole-house light show. The goal here is to go from scratch. Although this guide is intended for people who don’t know how to use linux at all and those who do alike, the focus is for people for whom linux and the raspberry pi are a complete mystery.

Looking to outdo your neighbours with your Christmas light show this year? YouTuber Makin’Things has created a beginners guide to setting up a Raspberry Pi–based musical light show for your facade, complete with information on soldering, wiring, and coding.

Once you’ve wrapped your house in metres and metres of lights and boosted your speakers so they can be heard for miles around, why not incorporate #cheerlights to make your outdoor decor interactive?

Still not enough? How about controlling your lights using a drum kit? Christian Kratky’s MIDI-Based Christmas Lights Animation system (or as I like to call it, House Rock) does exactly that.

Eye Of The Tiger (MIDI based christmas lights animation system prototype)

Any more?

We know these projects are just the tip of the iceberg when it comes to the Raspberry Pi–powered Christmas projects out there, and as always, we’d love you to share yours with us. So post a link in the comments below, or tag us on social media when posting your build photos, videos, and/or blog links. ‘Tis the season for sharing after all.

Sean Hodgins’ video-playing Christmas ornament

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/sean-hodgins-ornament/

Standard Christmas tree ornaments are just so boring, always hanging there doing nothing. Yawn! Lucky for us, Sean Hodgins has created an ornament that plays classic nineties Christmas adverts, because of nostalgia.

YouTube Christmas Ornament! – Raspberry Pi Project

This Christmas ornament will really take you back…

Ingredients

Sean first 3D printed a small CRT-shaped ornament resembling the family television set in The Simpsons. He then got to work on the rest of the components.

Pi Zero and electronic components — Sean Hodgins Raspberry Pi Christmas ornament

All images featured in this blog post are c/o Sean Hodgins. Thanks, Sean!

The ornament uses a Raspberry Pi Zero W, 2.2″ TFT LCD screen, Mono Amp, LiPo battery, and speaker, plus the usual peripherals. Sean purposely assembled it with jumper wires and tape, so that he can reuse the components for another project after the festive season.

By adding header pins to a PowerBoost 1000 LiPo charger, Sean was able to connect a switch to control the Pi’s power usage. This method is handy if you want to seal your Pi in a casing that blocks access to the power leads. From there, jumper wires connect the audio amplifier, LCD screen, and PowerBoost to the Zero W.

Code

Then, with Raspbian installed to an SD card and SSH enabled on the Zero W, Sean got the screen to work. The type of screen he used has both SPI and FBTFT enabled. And his next step was to set up the audio functionality with the help of an Adafruit tutorial.

For video playback, Sean installed mplayer before writing a program to extract video content from YouTube*. Once extracted, the video files are saved to the Raspberry Pi, allowing for seamless playback on the screen.

Construct

When fully assembled, the entire build fit snugly within the 3D-printed television set. And as a final touch, Sean added the cut-out lens of a rectangular magnifying glass to give the display the look of a curved CRT screen.

Then finally, the ornament hangs perfectly on the Christmas tree, up and running and spreading nostalgic warmth.

Have you created Raspberry Pi tree ornaments? Maybe you’ve 3D printed some of our own? We’d love to see what you’re doing with a Raspberry Pi this festive season, so make sure to share your projects with us, either in the comments below or via our social media channels.

 

*At this point, I should note that we don’t support the extraction of  video content from YouTube for your own use if you do not have the right permissions. However, since Sean’s device can play back any video, we think it would look great on your tree showing your own family videos from previous years. So, y’know, be good, be legal, and be festive.

The Pi Towers Secret Santa Babbage

Post Syndicated from Mark Calleja original https://www.raspberrypi.org/blog/secret-santa-babbage/

Tired of pulling names out of a hat for office Secret Santa? Upgrade your festive tradition with a Raspberry Pi, thermal printer, and everybody’s favourite microcomputer mascot, Babbage Bear.

Raspberry Pi Babbage Bear Secret Santa

The name’s Santa. Secret Santa.

It’s that time of year again, when the cosiness gets turned up to 11 and everyone starts thinking about jolly fat men, reindeer, toys, and benevolent home invasion. At Raspberry Pi, we’re running a Secret Santa pool: everyone buys a gift for someone else in the office. Obviously, the person you buy for has to be picked in secret and at random, or the whole thing wouldn’t work. With that in mind, I created Secret Santa Babbage to do the somewhat mundane task of choosing gift recipients. This could’ve just been done with some names in a hat, but we’re Raspberry Pi! If we don’t make a Python-based Babbage robot wearing a jaunty hat and programmed to spread Christmas cheer, who will?

Secret Santa Babbage

Ho ho ho!

Mecha-Babbage Xmas shenanigans

The script the robot runs is pretty basic: a list of names entered as comma-separated strings is shuffled at the press of a GPIO button, then a name is popped off the end and stored as a variable. The name is matched to a photo of the person stored on the Raspberry Pi, and a thermal printer pinched from Alex’s super awesome PastyCam (blog post forthcoming, maybe) prints out the picture and name of the person you will need to shower with gifts at the Christmas party. (Well, OK — with one gift. No more than five quid’s worth. Nothing untoward.) There’s also a redo function, just in case you pick yourself: press another button and the last picked name — still stored as a variable — is appended to the list again, which is shuffled once more, and a new name is popped off the end.

Secret Santa Babbage prototyping

Prototyping!

As the build was a bit of a rush job undertaken at the request of our ‘Director of Vibe’ Emily, there are a few things I’d like to improve about this functionality that I didn’t get around to — more on that later. To add some extra holiday spirit to the project at the last minute, I used Pygame to play a WAV file of Santa’s jolly laugh while Babbage chooses a name for you. The file is included in the GitHub repo along with everything else, because ‘tis the season, etc., etc.

Secret Santa Babbage prototyping

Editor’s note: Considering these desk adornments, Mark’s Secret Santa gift-giver has a lot to go on.

Writing the code for Xmas Mecha-Babbage was fairly straightforward, though it uses some tricky bits for managing the thermal printer. You’ll need to install the drivers to make it go, as well as the CUPS package for managing the print hosting. You can find instructions for these things here, thanks to the wonderful Adafruit crew. Also, for reasons I couldn’t fathom, this will all only work on a Pi 2 and not a Pi 3, as there are some compatibility issues with the thermal printer otherwise. (I also tested the script on a Pi Zero W…no dice.)

Building a Christmassy throne

The hardest (well, fiddliest) parts of making the whole build were constructing the throne and wiring the bear. Using MakerCase, Inkscape, a bit of ingenuity, and a laser cutter, I was able to rig up a Christmassy plywood throne which has a hole through the seat so I could run the wires down from Babbage and to the Pi inside. I finished the throne by rubbing a couple of fingers of beeswax into it; as well as making the wood shine just a little bit and protecting it against getting wet, this had the added bonus of making it smell awesome.

Next year’s iteration will be mulled wine–scented.

I next soldered two LEDs to some lengths of wire, and then ran the wires through holes at the top of the throne and down the back along a small channel I had carved with a narrow chisel to connect them to the Pi’s GPIO pins. The green LED will remain on as long as Babbage is running his program, and the red one will light up while he is processing your request. Once the red LED goes off again, the next person can have a go. I also laser-cut a final piece of wood to overlay the back of Babbage’s Xmas throne and cover the wiring a bit.

Creating a Xmas cyborg bear

Taking two 6 mm tactile buttons, I clipped the spiky metal legs off one side of each (the buttons were going into a stuffed christmas toy, after all) and soldered a length of wire to each of the remaining legs. Next, I made a small incision into Babbage with my trusty Swiss army knife (in a place that actually made me cringe a little) and fed the buttons up into his paws. At some point in this process I was standing in the office wrestling with the bear and muttering to myself, which elicited some very strange looks from my colleagues.

Secret Santa Babbage throne

Poor Babbage…

One thing to note here is to make sure the wires remain attached at the solder points while you push them up into Babbage’s paws. The first time I tried it, I snapped one of my connections and had to start again. It helped to remove some stuffing like a tunnel and then replace it afterward. Moreover, you can use your fingertip to support the joints as you poke the wire in. Finally, a couple of squirts of hot glue to keep Babbage’s furry cheeks firmly on the seat, and done!

Secret Santa Babbage

Next year: Game of Thrones–inspired candy cane throne

The Secret Santa Babbage masterpiece

The whole build process was the perfect holiday mix of cheerful and macabre, and while getting the thermal printer to work was a little time-consuming, the finished product definitely raised some smiles around the office and added a bit of interesting digital flavour to a staid office tradition. And it also helped people who are new to the office or from other branches of the Foundation to know for whom they will be buying a gift.

Secret Santa Babbage

Ready to dispense Christmas cheer!

There are a few ways in which I’ll polish this project before next year, such as having the script write the names to external text files to create a record that will persist in case of a reboot, and maybe having Secret Santa Babbage play you a random Christmas carol when you squeeze his paw instead of just laughing merrily every time. (I also thought about adding electric shocks for those people who are on the naughty list, but HR said no. Bah, humbug!)

Make your own

The code and laser cut plans for the whole build are available here. If you plan to make your own, let us know which stuffed toy you will be turning into a Secret Santa cyborg! And if you’ve been working on any other Christmas-themed Raspberry Pi projects, we’d like to see those too, so tag us on social media to share the festive maker cheer.
