Raspberry Pi at Scouts Wintercamp

As well as working with classroom teachers and supporting learning in schools, Raspberry Pi brings computing and digital making to educators and learners in all sorts of other settings. I recently attended Wintercamp, a camp for Scouts at Gilwell Park. With some help from Brian and Richard from Vodafone, I ran a Raspberry Pi activity space introducing Scouts to digital making with Raspberry Pi, using the Sense HAT, the Camera Module, and GPIO, based on some of our own learning resources.

Today I’m running @Raspberry_Pi activities for @UKScouting at @gpwintercamp with @VodafoneUK!

Note the plastic sheeting on the floor! Kids were dropping into our sessions all day with muddy boots, having taken part in all sorts of fun activities, indoors and out.

@gpwintercamp

In the UK, the Scouts have Digital Citizen and Digital Maker badges, and we’re currently working with the Scout Association to help deliver content for the Digital Maker badge, as supported by the Vodafone Foundation.

The activities we ran were just a gentle introduction to creative tech and experimenting with sensors, but they went down really well, and many of the participants felt happy to move beyond the worksheets and try out their own ideas. We set challenges, and got them to think about how they could incorporate technology like this into their Scouting activities.

Having been through the Scouting movement myself, it’s amazing to be involved in working to show young people how technology can be applied to projects related to their other hobbies and interests. I loved introducing the Scouts to the idea that programming and making can be tools to help solve problems that are relevant to them and to others in their communities, as well as enabling them to do some good in the world, and to be creative.

Can you breathe on the Sense HAT to make the humidity read 90?” “That’s cool. It makes you light-headed…

While conducting a survey of Raspberry Jam organisers recently, I discovered that a high proportion of those who run Jams are also involved in other youth organisations. Many were Scout leaders. Other active Pi community folk happen to be involved in Scouting too, like Brian and Richard, who helped out at the weekend, and who are Scout and Cub leaders. I’m interested to speak to anyone in the Pi community who has an affiliation with the Scouts to share ideas on how they think digital making can be incorporated in Scouting activities. Please do get in touch!

Not a great picture but the Scouts made a Fleur de Lys on the Sense HAT at @gpwintercamp

The timing is perfect for young people in this age group to get involved with digital making, as we’ve just launched our first Pioneers challenge. There’s plenty of scope there for outdoor tech projects.

Thanks to UK Scouting and the Wintercamp team for a great weekend. Smiles all round!

Hello World – a new magazine for educators

Today, the Raspberry Pi Foundation is launching a new, free resource for educators.

Hello World – a new magazine for educators

Hello World is a magazine about computing and digital making written by educators, for educators. With three issues each year, it contains 100 pages filled with news, features, teaching resources, reviews, research and much more. It is designed to be cross-curricular and useful to all kinds of educators, from classroom teachers to librarians.

Hello World is a magazine about computing and digital making written by educators, for educators. With three issues each year, it contains 100 pages filled with news, features, teaching resources, reviews, research and much more.

It is designed to be cross-curricular and useful to all kinds of educators, from classroom teachers to librarians.  While it includes lots of great examples of how educators are using Raspberry Pi computers in education, it is device- and platform-neutral.

Community building

As with everything we do at the Raspberry Pi Foundation, Hello World is about community building. Our goal is to provide a resource that will help educators connect, share great practice, and learn from each other.

Hello World is a collaboration between the Raspberry Pi Foundation and Computing at School, the grass-roots organisation of computing teachers that’s part of the British Computing Society. The magazine builds on the fantastic legacy of Switched On, which it replaces as the official magazine for the Computing at School community.

We’re thrilled that many of the contributors to Switched On have agreed to continue writing for Hello World. They’re joined by educators and researchers from across the globe, as well as the team behind the amazing MagPi, the official Raspberry Pi magazine, who are producing Hello World.

print (“Hello, World!”)

Hello World is available free, forever, for everyone online as a downloadable pdf.  The content is written to be internationally relevant, and includes features on the most interesting developments and best practices from around the world.

Thanks to the very generous support of our sponsors BT, we are also offering the magazine in a beautiful print version, delivered for free to the homes of serving educators in the UK.

Papert’s legacy 

This first issue is dedicated to Seymour Papert, in many ways the godfather of computing education. Papert was the creator of the Logo programming language and the author of some of the most important research on the role of computers in education. It will come at no surprise that his legacy has a big influence on our work at the Raspberry Pi Foundation, not least because one of our co-founders, Jack Lang, did a summer internship with Papert.

Inside you’ll find articles exploring Papert’s influence on how we think about learning, on the rise of the maker movement, and on the software that is used to teach computing today from Scratch to Greenfoot.

Get involved

We will publish three issues of Hello World a year, timed to coincide with the start of the school terms here in the UK. We’d love to hear your feedback on this first issue, and please let us know what you’d like to see covered in future issues too.

The magazine is by educators, for educators. So if you have experience, insights or practical examples that you can share, get in touch: [email protected].

Live-streaming YouTube Drone

I’ll be tweeting, recording, and schmoozing my way through day one of Bett tomorrow. One thing I sadly won’t be able to do is live-stream to YouTube via drone.

Turn Your Raspberry Pi into the Open Source Drone Youtube Live Video Streamer

Raspberry Pi Video Streamer Pack Now on Kickstarter! http://kck.st/2ef6gnD for SD Card image and how to write image to SD Card: https://youtu.be/lRd4BhN4BHk for more info: www.sixfab.com

However, thanks to this handy guide from Mahmut on Hackaday, such dreams could possibly be realised for future Raspberry Pi events, such as Skycademy and the Big Birthday Weekend.

YouTube Drone

Mahmut uses an LTE shield to supply 4G access to the onboard Raspberry Pi and Camera Module. Then, using the image he supplies here, you’re good to go.

If you want to make your own Pi-powered drone, you’ll find Greg Nichols’s step-by-step guide for building one here. Greg uses a Pi Zero and the total cost comes in under $200.

A Raspberry Pi Zero drone

This video shows a Linux drone made with the PXFmini (http://erlerobotics.com/blog/pxfmini/) autopilot shield for the Raspberry Pi Zero. The drone runs a customized Debian file system with real-time capabilities and the APM flight stack.

The small, lightweight nature of the Raspberry Pi makes it perfect for drone building. If you’ve made your own, we’d love to see it in the comments below.

The Raspberry Pi Foundation’s Digital Making Curriculum

At Raspberry Pi, we’re determined in our ambition to put the power of digital making into the hands of people all over the world: one way we pursue this is by developing high-quality learning resources to support a growing community of educators. We spend a lot of time thinking hard about what you can learn by tinkering and making with a Raspberry Pi, and other devices and platforms, in order to become skilled in computer programming, electronics, and physical computing.

Now, we’ve taken an exciting step in this journey by defining our own digital making curriculum that will help people everywhere learn new skills.

A PDF version of the curriculum is also available to download.

Who is it for?

We have a large and diverse community of people who are interested in digital making. Some might use the curriculum to help guide and inform their own learning, or perhaps their children’s learning. People who run digital making clubs at schools, community centres, and Raspberry Jams may draw on it for extra guidance on activities that will engage their learners. Some teachers may wish to use the curriculum as inspiration for what to teach their students.

Raspberry Pi produces an extensive and varied range of online learning resources and delivers a huge teacher training program. In creating this curriculum, we have produced our own guide that we can use to help plan our resources and make sure we cover the broad spectrum of learners’ needs.

Progression

Learning anything involves progression. You start with certain skills and knowledge and then, with guidance, practice, and understanding, you gradually progress towards broader and deeper knowledge and competence. Our digital making curriculum is structured around this progression, and in representing it, we wanted to avoid the age-related and stage-related labels that are often associated with a learner’s progress and the preconceptions these labels bring. We came up with our own, using characters to represent different levels of competence, starting with Creator and moving onto Builder and Developer before becoming a Maker.

Progress through our curriculum and become a digital maker

Strands

We want to help people to make things so that they can become the inventors, creators, and makers of tomorrow. Digital making, STEAM, project-based learning, and tinkering are at the core of our teaching philosophy which can be summed up simply as ‘we learn best by doing’.

We’ve created five strands which we think encapsulate key concepts and skills in digital making: Design, Programming, Physical Computing, Manufacture, and Community and Sharing.

Computational thinking

One of the Raspberry Pi Foundation’s aims is to help people to learn about computer science and how to make things with computers. We believe that learning how to create with digital technology will help people shape an increasingly digital world, and prepare them for the work of the future.

Computational thinking is at the heart of the learning that we advocate. It’s the thought process that underpins computing and digital making: formulating a problem and expressing its solution in such a way that a computer can effectively carry it out. Computational thinking covers a broad range of knowledge and skills including, but not limited to:

  • Logical reasoning
  • Algorithmic thinking
  • Pattern recognition
  • Abstraction
  • Decomposition
  • Debugging
  • Problem solving

By progressing through our curriculum, learners will develop computational thinking skills and put them into practice.

What’s not on our curriculum?

If there’s one thing we learned from our extensive work in formulating this curriculum, it’s that no two educators or experts can agree on the best approach to progression and learning in the field of digital making. Our curriculum is intended to represent the skills and thought processes essential to making things with technology. We’ve tried to keep the headline outcomes as broad as possible, and then provide further examples as a guide to what could be included.

Our digital making curriculum is not intended to be a replacement for computer science-related curricula around the world, such as the ‘Computing Programme of Study’ in England or the ‘Digital Technologies’ curriculum in Australia. We hope that following our learning pathways will support the study of formal curricular and exam specifications in a fun and tangible way. As we continue to expand our catalogue of free learning resources, we expect our curriculum will grow and improve, and your input into that process will be vital.

Get involved

We’re proud to be part of a movement that aims to empower people to shape their world through digital technologies. We value the support of our community of makers, educators, volunteers, and enthusiasts. With this in mind, we’re interested to hear your thoughts on our digital making curriculum. Add your feedback to this form, or talk to us at one of the events that Raspberry Pi will attend in 2017.

Harry Potter and the Real-life Weasley Clock

Pat Peters (such a wonderful Marvel-sounding name) recently shared his take on the Weasley Clock, a device that hangs on the wall of The Burrow, the rickety home inhabited by the Weasley family in the Harry Potter series.

Mrs. Weasley glanced at the grandfather clock in the corner. Harry liked this clock. It was completely useless if you wanted to know the time, but otherwise very informative. It had nine golden hands, and each of them was engraved with one of the Weasley family’s names. There were no numerals around the face, but descriptions of where each family member might be. “Home,” “school,” and “work” were there, but there was also “traveling,” “lost,” “hospital,” “prison,” and, in the position where the number twelve would be on a normal clock, “mortal peril.”

The clock in the movie has misplaced “mortal peril”, but aside from that it looks a lot like what we’d imagined from the books.

There’s a reason why more and more Harry Potter-themed builds are appearing online. The small size of devices such as the Raspberry Pi and Arduino allow for a digital ‘brain’ to live within an ordinary object, allowing control over it that you could easily confuse with magic… if you allow yourself to believe in such things.

So with last week’s Real-life Daily Prophet doing so well, it’s only right to share another Harry Potter-inspired project.

Harry Potter Weasley Clock

The clock serves not to tell the time but, rather, to indicate the location of Molly, Arthur, and the horde of Weasley children. And using the OwnTracks GPS app for smartphones, Pat’s clock does exactly the same thing.

Pat Peters Weasley Clock Raspberry Pi

Pat has posted the entire build on instructables, allowing every budding witch and wizard (and possibly a curious Muggle or two) the chance to build their own Weasley Clock.

This location clock works through a Raspberry Pi which subscribes to an MQTT broker that our phones publish events to. Our phones (running the OwnTracks GPS app) send a message to the broker whenever we cross into or out of one of our waypoints that we have set up in OwnTracks; this then triggers the Raspberry Pi to run a servo that moves the clock hand to show our location.

There are no words for how much we love this. Here at Pi Towers we definitely have a soft spot for Harry Potter-themed builds, so make sure to share your own with us in the comments below, or across our social media channels on Facebook, Twitter, Instagram, YouTube and G+.

Book-wrangling at Wordery with a Raspberry Pi

While we mostly deal in pretty technologically advanced stuff here at Pi Towers, we are huge fans of the printed word too. It’s great to hear, then, that the Raspberry Pi has been helping booksellers to keep bibliophiles like us supplied with all the reading matter they could wish for. Jeff Podolski, IT and network technician at Wordery, recently got in touch to tell us just how his company has been using the Pi in their warehouse.

At work in the Wordery warehouse.

Wordery is an online bookshop which offers over 10 million books, including a wide range of Raspberry Pi titles. Jeff tells us that the company has been working on improving their productivity and customer service over the past few years, with a recent drive towards greater automation in our sorting and distribution operation. “We needed to get PCs on the desks used for packing and mailing, so we could track packed items and provide interactive feedback for our staff,” says Jeff. A PC with a screen and barcode scanner on a desk takes up considerable space and power, so the IT team came up with the idea of using Raspberry Pis instead.

After some initial tests using a Pi and a standard PC screen, Jeff and his team streamlined the setup using the official 7” screen and case, along with a USB barcode scanner. This allowed them to have a unit on the desk which took up one fifth of the space a PC would have needed, while using dramatically less power.

The Pi and touchscreen assembly

Jeff’s next challenge was to keep the Raspberry Pi safe from being knocked and bumped by all the items being packed, lest an unsecured Pi become a Pi smashed on the warehouse floor. “We found an excellent tablet mounting arm designed for wheelchairs: we simply clamped that to the table and attached a back-board to the tablet bracket,” Jeff explains. “We were then able to attach the Pi using the rear mounting screw holes”. After a little tidying of cables, Jeff and the team had created a small, low-power, easily movable interactive terminal which can be used by all the staff in the warehouse.

A mobile terminal, thanks to a hacked tablet holder

The project was such a success that over 40 of these terminals have now been installed, and the benefits are already clear to see. “This year we have been able to process record volumes through our warehouse, up 11% on the previous year,” notes Jeff. “The Pis were key to us handling this additional volume, enabling us to increase packing productivity by 30%. The beauty of a project like this is we’re now advocating using these Raspberry Pi terminals elsewhere in the building, further reducing our power consumption and equipment costs”.

We’re really happy to see the success of a project like this: it shows how the Raspberry Pi can make automation much cheaper and more accessible, as well as much more flexible. Jeff’s team did a great job of hacking the tablet arm to make it fit another purpose, too. It also really speaks volumes of the helpfulness and engagement of the Raspberry Pi community. The team at ModMyPi helped with sourcing large amounts of kit and cables, as well as the cases themselves. The Raspberry Pi Thin Client Project worked on making a simple, configurable thin client for Jeff’s team to use. Finally, Martin Kirst, the lead programmer on the open-source project TN525j, helped Jeff and his team to make the terminal emulator screens easily readable and to add new functionality to the units.

Using the Pi enabled Wordery to work more efficiently

Thank you for sharing your work with us, Jeff: it shows what great work you can do with the Raspberry Pi in an industrial setting.

In celebration of the success of this Pi-powered automation project, the nice folks at Wordery are offering a discount on Raspberry Pi titles on Wordery.com until the end of January: use the code “HAPPYREADING” and receive 10% off your second book. Wordery offer free delivery on all orders too.

Compute Module 3 Launch!

Way back in April of 2014 we launched the original Compute Module (CM1), which was based around the BCM2835 processor of the original Raspberry Pi. CM1 was a great success and we’ve seen a lot of uptake from various markets, particularly in IoT and home and factory automation. Not to be outdone by its bigger Raspberry Pi brother, the Compute Module is also destined for space!

Compute Module 3

Since releasing the original Compute Module, we’ve launched 2 further generations of much faster Raspberry Pi boards, so today we bring you the shiny new Compute Module 3 (CM3); this is based on the Raspberry Pi 3 hardware, providing twice the RAM and roughly 10x the CPU performance of the original Module. We’ve been talking about the Compute Module 3 since the launch of the Raspberry Pi 3, and we’re already excited to see NEC displays, an early adopter, launching their CM3-enabled display solution.

Compute Module 3

The idea of the Compute Module was to provide an easy and cost-effective route to producing customised products based on the Pi hardware and software platform. The thought was to provide the ‘team in a garage’ with easy access to the same technology as the big guys. The Module takes care of the complexity of routing out the processor pins, the high speed RAM interface, and core power supply, and allows a simple carrier board to provide just what is needed in terms of external interfaces and form factor. The module uses a standard DDR2 SODIMM form factor, sockets for which are made by several manufacturers, are easily available, and are inexpensive.

In fact, today we are launching two versions of Compute Module 3. The first is the ‘standard’ CM3 which has a BCM2837 processor at up to 1.2GHz with 1GByte RAM, the same as Pi3, and 4Gbytes of on-module eMMC flash. The second version is what we are calling ‘Compute Module 3 Lite’ (CM3L) which still has the same BCM2837 and 1Gbyte of RAM, but brings the SD card interface to the Module pins so a user can wire this up to an eMMC or SD card of their choice.

Back side of CM3 (left) and CM3L (right).

We are also releasing an updated version of our get-you-started breakout board, the Compute Module IO Board V3 (CMIO3). This board provides the necessary power to the Module and gives you the ability to program the Module’s flash memory (for the non-Lite versions) or use an SD card (Lite versions), access the processor interfaces in a slightly more friendly fashion (pin headers and flexi connectors, much like the Pi), and provides the necessary HDMI and USB connectors so that you have an entire system that can boot Raspbian (or the OS of your choice). This board provides both a starting template for those who want to design with the Compute Module, and a quick way to start experimenting with the hardware, and building and testing a system, before going to the expense of fabricating a custom board. The CMIO3 can accept an original Compute Module, CM3, or CM3L.

Comprehensive information on the Compute Modules is available in the relevant hardware documentation section of our website, and includes a datasheet and schematics.

With the launch of CM3 and CM3 Lite, we are not obsoleting the original Compute Module; we still see this as a valid product in its own right, being a lower-cost and lower-power option where the performance of a CM3 would be overkill.

CM3 and CM3L are priced at $30 and $25 respectively (excluding tax and shipping), and this price applies to any size order. The original Compute Module is also reduced to $25. Our partners RS and Premier Farnell are also providing full development kits, which include all you need to get started designing with the Compute Module 3.

The CM3 is largely backwards-compatible with CM1 designs which have followed our design guidelines. The caveats are that the Module is 1mm taller than the original Module, and the processor core supply (VBAT) can draw significantly more current. Consequently, the processor itself will run much hotter under heavy CPU load, so designers need to consider thermals based on expected use cases.

We’re very glad to finally be launching the Compute Module 3, and we’re excited to see what people do with it. Head on over to our partners element14 (or Farnell UK) and RS Components to buy yours today!
