Astro Pi upgrades launch today!

Post Syndicated from David Honess original https://www.raspberrypi.org/blog/astro-pi-upgrades-launch/

Before our beloved SpaceDave left the Raspberry Pi Foundation to join the ranks of the European Space Agency (ESA) — and no, we’re still not jealous *ahem* — he kindly drafted us one final blog post about the Astro Pi upgrades heading to the International Space Station today! So here it is. Enjoy!

We are very excited to announce that Astro Pi upgrades are on their way to the International Space Station! Back in September, we blogged about a small payload being launched to the International Space Station to upgrade the capabilities of our Astro Pi units.

Sneak peek

For the longest time, the payload was scheduled to be launched on SpaceX CRS 14 in February. However, the launch was delayed to April and so impacted the flight operations we have planned for running Mission Space Lab student experiments.

To avoid this, ESA had the payload transferred to Russian Soyuz MS-08 (54S), which is launching today to carry crew members Oleg Artemyev, Andrew Feustel, and Ricky Arnold to the ISS.

L-47 hours.

You can watch coverage of the launch on NASA TV from 4.30pm GMT this afternoon, with the launch scheduled for 5.44pm GMT. Check the NASA TV schedule for updates.

The upgrades

The pictures below show the flight hardware in its final configuration before loading onto the launch vehicle.

All access

With the wireless dongle, the Astro Pi units can be deployed in ISS locations other than the Columbus module, where they don’t have access to an Ethernet switch.

We are also sending some flexible optical filters. These are made from the same material as the blue square which is shipped with the Raspberry Pi NoIR Camera Module.

So that future Astro Pi code will need to command fewer windows to download earth observation imagery to the ground, we’re also including some 32GB micro SD cards to replace the current 8GB cards.

It’s ziplock bags all the way down up

Once the Soyuz docks with the ISS, this payload is one of the first which will be unpacked, so that the Astro Pi units can be upgraded and deployed ready to run your experiments!

More Astro Pi

Stay tuned for our next update in April, when student code is set to be run on the Astro Pi units as part of our Mission Space Lab programme. And to find out more about Astro Pi, head to the programme website.

Our 2017 Annual Review

Post Syndicated from Oliver Quinlan original https://www.raspberrypi.org/blog/annual-review-2017/

Each year we take stock at the Raspberry Pi Foundation, looking back at what we’ve achieved over the previous twelve months. We’ve just published our Annual Review for 2017, reflecting on the progress we’ve made as a foundation and a community towards putting the power of digital making in the hands of people all over the world.

In the review, you can find out about all the different education programmes we run. Moreover, you can hear from people who have taken part, learned through making, and discovered they can do things with technology that they never thought they could.

Growing our reach

Our reach grew hugely in 2017, and the numbers tell this story.

By the end of 2017, we’d sold over 17 million Raspberry Pi computers, bringing tools for learning programming and physical computing to people all over the world.

Vibrant learning and making communities

Code Club grew by 2964 clubs in 2017, to over 10000 clubs across the world reaching over 150000 9- to 13-year-olds.

“The best moment is seeing a child discover something for the first time. It is amazing.”
– Code Club volunteer

In 2017 CoderDojo became part of the Raspberry Pi family. Over the year, it grew by 41% to 1556 active Dojos, involving nearly 40000 7- to 17-year-olds in creating with code and collaborating to learn about technology.

Raspberry Jams continued to grow, with 18700 people attending events organised by our amazing community members.



Supporting teaching and learning

We reached 208 projects in our online resources in 2017, and 8.5 million people visited these to get making.

“I like coding because it’s like a whole other language that you have to learn, and it creates something very interesting in the end.”
– Betty, Year 10 student

2017 was also the year we began offering online training courses. 19000 people joined us to learn about programming, physical computing, and running a Code Club.



Over 6800 young people entered Mission Zero and Mission Space Lab, 2017’s two Astro Pi challenges. They created code that ran on board the International Space Station or will run soon.

More than 600 educators joined our face-to-face Picademy training last year. Our community of Raspberry Pi Certified Educators grew to 1500, all leading digital making across schools, libraries, and other settings where young people learn.

Being social

Well over a million people follow us on social media, and in 2017 we’ve seen big increases in our YouTube and Instagram followings. We have been creating much more video content to share what we do with audiences on these and other social networks.

The future

It’s been a big year, as we continue to reach even more people. This wouldn’t be possible without the amazing work of volunteers and community members who do so much to create opportunities for others to get involved. Behind each of these numbers is a person discovering digital making for the first time, learning new skills, or succeeding with a project that makes a difference to something they care about.

Simulate sand with Adafruit’s newest project

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/simulate-sand-with-adafruits-newest-project/

The Ruiz brothers at Adafruit have used Phillip Burgess’s PixieDust code to turn a 64×64 LED Matrix and a Raspberry Pi Zero into an awesome sand toy that refuses to defy the laws of gravity. Here’s how to make your own.

BIG LED Sand Toy – Raspberry Pi RGB LED Matrix

Simulated LED Sand Physics! These LEDs interact with motion and looks like they’re affect by gravity. An Adafruit LED matrix displays the LEDs as little grains of sand which are driven by sampling an accelerometer with Raspberry Pi Zero!

Obey gravity

As the latest addition to their online learning system, Adafruit have produced the BIG LED Sand Toy, or as I like to call it, Have you seen this awesome thing Adafuit have made?

Adafruit Sand Toy Raspberry Pi

The build uses a Raspberry Pi Zero, a 64×64 LED matrix, the Adafruit RGB Matrix Bonnet, 3D-printed parts, and a few smaller peripherals. Find the entire tutorial, including downloadable STL files, on their website.

How does it work?

Alongside the aforementioned ingredients, the project utilises the Adafruit LIS3DH Triple-Axis Accelerometer. This sensor is packed with features, and it allows the Raspberry Pi to control the virtual sand depending on how the toy is moved.

Adafruit Sand Toy Raspberry Pi

The Ruiz brothers inserted an SD card loaded with Raspbian Lite into the Raspberry Pi Zero, installed the LED Matrix driver, cloned the Adafruit_PixieDust library, and then just executed the code. They created some preset modes, but once you’re comfortable with the project code, you’ll be able to add your own take on the project.

Accelerometers and Raspberry Pi

This isn’t the first time a Raspberry Pi has met an accelerometer: the two Raspberry Pis aboard the International Space Station for the Astro Pi mission both have accelerometers thanks to their Sense HATs.

Comprised of a bundle of sensors, an LED matrix, and a five-point joystick, the Sense HAT is a great tool for exploring your surroundings with the Raspberry Pi, as well as for using your surroundings to control the Pi. You can find a whole variety of Sense HAT–based projects and tutorials on our website.

And if you’d like to try out the Sense HAT, including its onboard accelerometer, without purchasing one, head over to our online emulator, or use the emulator preinstalled on Raspbian.

Mission Space Lab flight status announced!

Post Syndicated from Erin Brindley original https://www.raspberrypi.org/blog/mission-space-lab-flight-status-announced/

In September of last year, we launched our 2017/2018 Astro Pi challenge with our partners at the European Space Agency (ESA). Students from ESA membership and associate countries had the chance to design science experiments and write code to be run on one of our two Raspberry Pis on the International Space Station (ISS).

Astro Pi Mission Space Lab logo

Submissions for the Mission Space Lab challenge have just closed, and the results are in! Students had the opportunity to design an experiment for one of the following two themes:

  • Life in space
    Making use of Astro Pi Vis (Ed) in the European Columbus module to learn about the conditions inside the ISS.
  • Life on Earth
    Making use of Astro Pi IR (Izzy), which will be aimed towards the Earth through a window to learn about Earth from space.

ESA astronaut Alexander Gerst, speaking from the replica of the Columbus module at the European Astronaut Center in Cologne, has a message for all Mission Space Lab participants:

Astro Pi celebrates anniversary of ISS Columbus module

Post Syndicated from David Honess original https://www.raspberrypi.org/blog/astro-pi-celebrates-anniversary/

Right now, 400km above the Earth aboard the International Space Station, are two very special Raspberry Pi computers. They were launched into space on 6 December 2015 and are, most assuredly, the farthest-travelled Raspberry Pi computers in existence. Each year they run experiments that school students create in the European Astro Pi Challenge.

The European Columbus module

Today marks the tenth anniversary of the launch of the European Columbus module. The Columbus module is the European Space Agency’s largest single contribution to the ISS, and it supports research in many scientific disciplines, from astrobiology and solar science to metallurgy and psychology. More than 225 experiments have been carried out inside it during the past decade. It’s also home to our Astro Pi computers.

Here’s a video from 7 February 2008, when Space Shuttle Atlantis went skywards carrying the Columbus module in its cargo bay.

STS-122 Launch NASA TV Coverage

From February 7th, 2008 NASA-TV Coverage of The 121st Space Shuttle Launch Launched At:2:45:30 P.M E.T – Coverage begins exactly one hour till launch STS-122 Crew:

Today, coincidentally, is also the deadline for the European Astro Pi Challenge: Mission Space Lab. Participating teams have until midnight tonight to submit their experiments.

Anniversary celebrations

At 16:30 GMT today there will be a live event on NASA TV for the Columbus module anniversary with NASA flight engineers Joe Acaba and Mark Vande Hei.

Our Astro Pi computers will be joining in the celebrations by displaying a digital birthday candle that the crew can blow out. It works by detecting an increase in humidity when someone blows on it. The video below demonstrates the concept.

AstroPi candle

Uploaded by Effi Edmonton on 2018-01-17.

Do try this at home

The exact Astro Pi code that will run on the ISS today is available for you to download and run on your own Raspberry Pi and Sense HAT. You’ll notice that the program includes code to make it stop automatically when the date changes to 8 February. This is just to save time for the ground control team.

If you have a Raspberry Pi and a Sense HAT, you can use the terminal commands below to download and run the code yourself:

wget http://rpf.io/colbday -O birthday.py
chmod +x birthday.py
./birthday.py

When you see a blank blue screen with the brightness increasing, the Sense HAT is measuring the baseline humidity. It does this every 15 minutes so it can recalibrate to take account of natural changes in background humidity. A humidity increase of 2% is needed to blow out the candle, so if the background humidity changes by more than 2% in 15 minutes, it’s possible to get a false positive. Press Ctrl + C to quit.

Please tweet pictures of your candles to @astro_pi – we might share yours! And if we’re lucky, we might catch a glimpse of the candle on the ISS during the NASA TV event at 16:30 GMT today.

Astro Pi Mission Zero: your code is in space

Post Syndicated from David Honess original https://www.raspberrypi.org/blog/astro-pi-mission-zero-day/

Every school year, we run the European Astro Pi challenge to find the next generation of space scientists who will program two space-hardened Raspberry Pi units, called Astro Pis, living aboard the International Space Station.

Astro Pi Mission Zero

The 2017–2018 challenge included the brand-new non-competitive Mission Zero, which guaranteed that participants could have their code run on the ISS for 30 seconds, provided they followed the rules. They would also get a certificate showing the exact time period during which their code ran in space.

Astro Pi Mission Zero logo

We asked participants to write a simple Python program to display a personalised message and the air temperature on the Astro Pi screen. No special hardware was needed, since all the code could be written in a web browser using the Sense HAT emulator developed in partnership with Trinket.

Scott McKenzie on Twitter

Students coding #astropi emulator to scroll a message to astronauts on @Raspberry_Pi in space this summer. Try it here: https://t.co/0KURq11X0L #Rm9Parents #CSforAll #ontariocodes

And now it’s time…

We received over 2500 entries for Mission Zero, and we’re excited to announce that tomorrow all entries with flight status will be run on the ISS…in SPAAACE!

There are 1771 Python programs with flight status, which will run back-to-back on Astro Pi VIS (Ed). The whole process will take about 14 hours. This means that everyone will get a timestamp showing 1 February, so we’re going to call this day Mission Zero Day!

Part of each team’s certificate will be a map, like the one below, showing the exact location of the ISS while the team’s code was running.

The grey line is the ISS orbital path, the red marker shows the ISS’s location when their code was running. Produced using Google Static Maps API.

The programs will be run in the same sequence in which we received them. For operational reasons, we can’t guarantee that they will run while the ISS flies over any particular location. However, if you have submitted an entry to Mission Zero, there is a chance that your code will run while the ISS is right overhead!

Go out and spot the station

Spotting the ISS is a great activity to do by yourself or with your students. The station looks like a very fast-moving star that crosses the sky in just a few minutes. If you know when and where to look, and it’s not cloudy, you literally can’t miss it.

Source Andreas Möller, Wikimedia Commons.

The ISS passes over most ground locations about twice a day. For it to be clearly visible though, you need darkness on the ground with sunlight on the ISS due to its altitude. There are a number of websites which can tell you when these visible passes occur, such as NASA’s Spot the Station. Each of the sites requires you to give your location so it can work out when visible passes will occur near you.

Visible ISS pass star chart from Heavens Above, on which familiar constellations such as the Plough (see label Ursa Major) can be seen.

A personal favourite of mine is Heavens Above. It’s slightly more fiddly to use than other sites, but it produces brilliant star charts that show you precisely where to look in the sky. This is how it works:

  1. Go to www.heavens-above.com
  2. To set your location, click on Unspecified in the top right-hand corner
  3. Enter your location (e.g. Cambridge, United Kingdom) into the text box and click Search
  4. The map should change to the correct location — scroll down and click Update
  5. You’ll be taken back to the homepage, but with your location showing at the top right
  6. Click on ISS in the Satellites section
  7. A table of dates will now show, which are the upcoming visible passes for your location
  8. Click on a row to view the star chart for that pass — the line is the path of the ISS, and the arrow shows direction of travel
  9. Be outside in cloudless weather at the start time, look towards the direction where the line begins, and hope the skies stay clear

If you go out and do this, then tweet some pictures to @raspberry_pi, @astro_pi, and @esa. Good luck!

More Astro Pi

Mission Zero certificates will be arriving in participants’ inboxes shortly. We would like to thank everyone who participated in Mission Zero this school year, and we hope that next time you’ll take it one step further and try Mission Space Lab.

Mission Zero and Mission Space Lab are two really exciting programmes that young people of all ages can take part in. If you would like to be notified when the next round of Astro Pi opens for registrations, sign up to our mailing list here.

Create SLUG! It’s just like Snake, but with a slug

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/slug-snake/

Recreate Snake, the favourite mobile phone game from the late nineties, using a slug*, a Raspberry Pi, a Sense HAT, and our free resource!

Raspberry Pi Sense HAT Slug free resource

*A virtual slug. Not a real slug. Please leave the real slugs out in nature.

Snake SLUG!

Move aside, Angry Birds! On your bike, Pokémon Go! When it comes to the cream of the crop of mobile phone games, Snake holds the top spot.

Snake Nokia Game

I could while away the hours…

You may still have an old Nokia 3310 lost in the depths of a drawer somewhere — the drawer that won’t open all the way because something inside is jammed at an odd angle. So it will be far easier to grab your Pi and Sense HAT, or use the free Sense HAT emulator (online or on Raspbian), and code Snake SLUG yourself. In doing so, you can introduce the smaller residents of your household to the best reptile-focused game ever made…now with added mollusc.

The resource

To try out the game for yourself, head to our resource page, where you’ll find the online Sense HAT emulator embedded and ready to roll.

Raspberry Pi Sense HAT Slug free resource

It’ll look just like this, and you can use your computer’s arrow keys to direct your slug toward her tasty treats.

From there, you’ll be taken on a step-by-step journey from zero to SLUG glory while coding your own versionof the game in Python. On the way, you’ll learn to work with two-dimensional lists and to use the Sense HAT’s pixel display and joystick input. And by completing the resource, you’ll expand your understanding of applying abstraction and decomposition to solve more complex problems, in line with our Digital Making Curriculum.

The Sense HAT

The Raspberry Pi Sense HAT was originally designed and made as part of the Astro Pi mission in December 2015. With an 8×8 RGB LED matrix, a joystick, and a plethora of on-board sensors including an accelerometer, gyroscope, and magnetometer, it’s a great add-on for your digital making toolkit, and excellent for projects involving data collection and evaluation.

You can find more of our free Sense HAT tutorials here, including for making Flappy Bird Astronaut, a marble maze, and Pong.

Manufacturing Astro Pi case replicas

Post Syndicated from Janina Ander original https://www.raspberrypi.org/blog/astro-pi-case-guest-post/

Tim Rowledge produces and sells wonderful replicas of the cases which our Astro Pis live in aboard the International Space Station. Here is the story of how he came to do this. Over to you, Tim!

When the Astro Pi case was first revealed a couple of years ago, the collective outpouring of ‘Squee!’ it elicited may have been heard on board the ISS itself. People wanted to buy it or build it at home, and someone wanted to know whether it would blend. (There’s always one.)

The complete Astro Pi

The Sense HAT and its Pi tucked snugly in the original Astro Pi flight case — gorgeous, isn’t it?

Replicating the Astro Pi case

Some months later the STL files for printing your own Astro Pi case were released, and people jumped at the chance to use them. Soon reports appeared saying you had to make quite a few attempts before getting a good print — normal for any complex 3D-printing project. A fellow member of my local makerspace successfully made a couple of cases, but it took a lot of time, filament, and post-print finishing work. And of course, a plastic Astro Pi case simply doesn’t look or feel like the original made of machined aluminium — or ‘aluminum’, as they tend to say over here in North America.

I wanted to build an Astro Pi case which would more closely match the original. Fortunately, someone else at my makerspace happens to have some serious CNC machining equipment at his small manufacturing company. Therefore, I focused on creating a case design that could be produced with his three-axis device. This meant simplifying some parts to avoid expensive, slow, complex multi-fixture work. It took us a while, but we ended up with a design we can efficiently make using his machine.

And the resulting case looks really, really like the original — in fact, upon receiving one of the final prototypes, Eben commented:

“I have to say, at first glance they look spectacular: unless you hold them side by side with the originals, it’s hard to pinpoint what’s changed. I’m looking forward to seeing one built up and then seeing them in the wild.”

Inside the Astro Pi case

Making just the bare case is nice, but there are other parts required to recreate a complete Astro Pi unit. Thus I got my local electronics company to design a small HAT to provide much the same support the mezzanine board offers: an RTC and nice, clean connections to the six buttons. We also added well-labelled, grouped pads for all the other GPIO lines, along with space for an ADC. If you’re making your own Astro Pi replica, you might like the Switchboard.

The electronics supply industry just loves to offer *some* of what you need, so that one supplier never has everything: we had to obtain the required stand-offs, screws, spacers, and JST wires from assorted other sources. Jeff at my nearby Industrial Paint & Plastics took on the laser engraving of our cases, leaving out copyrighted logos etcetera.

Should you like to buy one of our Astro Pi case kits, pop over to www.astropicase.com, and we’ll get it on its way to you pronto. If you’re an institutional or corporate customer, the fully built option might make more sense for you — ordering the Pi and other components, and having a staff member assemble it all, may well be more work than is sensible.

To put the kit together yourself, all you need to do is add a Pi, Sense HAT, Camera Module, and RTC battery, and choose your buttons. An illustrated manual explains the process step by step. Our version of the Astro Pi case uses the same APEM buttons as the units in orbit, and whilst they are expensive, just clicking them is a source of great joy. It comes in a nice travel case too.

The possibilities of the Sense HAT

Post Syndicated from Janina Ander original https://www.raspberrypi.org/blog/sense-hat-projects/

Did you realise the Sense HAT has been available for over two years now? Used by astronauts on the International Space Station, the exact same hardware is available to you on Earth. With a new Astro Pi challenge just launched, it’s time for a retrospective/roundup/inspiration post about this marvellous bit of kit.

The Sense HAT explained

We developed our scientific add-on board to be part of the Astro Pi computers we sent to the International Space Station with ESA astronaut Tim Peake. For a play-by-play of Astro Pi’s history, head to the blog archive.

Just to remind you, this is all the cool stuff our engineers have managed to fit onto the HAT:

  • A gyroscope (sensing pitch, roll, and yaw)
  • An accelerometer
  • A magnetometer
  • Sensors for temperature, humidity, and barometric pressure
  • A joystick
  • An 8×8 LED matrix

You can find a roundup of the technical specs here on the blog.

How to Sense HAT

It’s easy to begin exploring this device: take a look at our free Getting started with the Sense HAT resource, or use one of our Code Club Sense HAT projects. You can also try out the emulator, available offline on Raspbian and online on Trinket.

Sense HAT emulator on Trinket

The Sense HAT emulator on trinket.io

Fun and games with the Sense HAT

Use the LED matrix and joystick to recreate games such as Pong or Flappy Bird. Of course, you could also add sensor input to your game: code an egg drop game or a Magic 8 Ball that reacts to how the device moves.

Sense HAT Random Sparkles

Create random sparkles on the Sense HAT

Once December rolls around, you could brighten up your home with a voice-controlled Christmas tree or an advent calendar on your Sense HAT.

If you like the great outdoors, you could also use your Sense HAT to recreate this Hiking Companion by Marcus Johnson. Take it with you on your next hike!

Art with the Sense HAT

The LED matrix is perfect for getting creative. To draw something basic without having to squint at a Python list, use this app by our very own Richard Hayler. Feeling more ambitious? The MagPi will teach you how to create magnificent pixel art. Ben Nuttall has created this neat little Python script for displaying a photo taken by the Raspberry Pi Camera Module on the Sense HAT.

Brett Haines Mathematica on the Sense HAT

It’s also possible to incorporate Sense HAT data into your digital art! The Python Turtle module and the Processing language are both useful tools for creating beautiful animations based on real-world information.

A Sense HAT project that also uses this principle is Giorgio Sancristoforo’s Tableau, a ‘generative music album’. This device creates music according to the sensor data:

Tableau Generative Album

“There is no doubt that, as music is removed by the phonographrecord from the realm of live production and from the imperative of artistic activity and becomes petrified, it absorbs into itself, in this process of petrification, the very life that would otherwise vanish.”

Science with the Sense HAT

This free Essentials book from The MagPi team covers all the Sense HAT science basics. You can, for example, learn how to measure gravity.

Cropped cover of Experiment with the Sense HAT book

Our online resource shows you how to record the information your HAT picks up. Next you can analyse and graph your data using Mathematica, which is included for free on Raspbian. This resource walks you through how this software works.

If you’re seeking inspiration for experiments you can do on our Astro Pis Izzy and Ed on the ISS, check out the winning entries of previous rounds of the Astro Pi challenge.

But you can also stick to terrestrial scientific investigations. For example, why not build a weather station and share its data on your own web server or via Weather Underground?

Your code in space!

If you’re a student or an educator in one of the 22 ESA member states, you can get a team together to enter our 2017-18 Astro Pi challenge. There are two missions to choose from, including Mission Zero: follow a few guidelines, and your code is guaranteed to run in space!

Announcing the 2017-18 European Astro Pi challenge!

Post Syndicated from David Honess original https://www.raspberrypi.org/blog/announcing-2017-18-astro-pi/

Astro Pi is back! Today we’re excited to announce the 2017-18 European Astro Pi challenge in partnership with the European Space Agency (ESA). We are searching for the next generation of space scientists.

YouTube

Enjoy the videos and music you love, upload original content, and share it all with friends, family, and the world on YouTube.

Astro Pi is an annual science and coding competition where student-written code is run on the International Space Station under the oversight of an ESA astronaut. The challenge is open to students from all 22 ESA member countries, including — for the first time — associate members Canada and Slovenia.

The format of the competition is changing slightly this year, and we also have a brand-new non-competitive mission in which participants are guaranteed to have their code run on the ISS for 30 seconds!

Mission Zero

Until now, students have worked on Astro Pi projects in an extra-curricular context and over multiple sessions. For teachers and students who don’t have much spare capacity, we wanted to provide an accessible activity that teams can complete in just one session.

So we came up with Mission Zero for young people no older than 14. To complete it, form a team of two to four people and use our step-by-step guide to help you write a simple Python program that shows your personal message and the ambient temperature on the Astro Pi. If you adhere to a few rules, your code is guaranteed to run in space for 30 seconds, and you’ll receive a certificate showing the exact time period during which your code has run in space. No special hardware is needed for this mission, since everything is done in a web browser.

Mission Zero is open until 26 November 2017! Find out more.

Mission Space Lab

Students aged up to 19 can take part in Mission Space Lab. Form a team of two to six people, and work like real space scientists to design your own experiment. Receive free kit to work with, and write the Python code to carry out your experiment.

There are two themes for Mission Space Lab teams to choose from for their projects:

  • Life in space
    You will make use of Astro Pi Vis (“Ed”) in the European Columbus module. You can use all of its sensors, but you cannot record images or videos.
  • Life on Earth
    You will make use of Astro Pi IR (“Izzy”), which will be aimed towards the Earth through a window. You can use all of its sensors and its camera.

The Astro Pi kit, delivered to Space Lab teams by ESA

If you achieve flight status, your code will be uploaded to the ISS and run for three hours (two orbits). All the data that your code records in space will be downloaded and returned to you for analysis. Then submit a short report on your findings to be in with a chance to win exclusive, money-can’t-buy prizes! You can also submit your project for a Bronze CREST Award.

Mission Space Lab registration is open until 29 October 2017, and accepted teams will continue to spring 2018. Find out more.

How do I get started?

There are loads of materials available that will help you begin your Astro Pi journey — check out the Getting started with the Sense HAT resource and this video explaining how to build the flight case.

Questions?

If you have any questions, please post them in the comments below. We’re standing by to answer them!

Astro Pi upgrades on the International Space Station

Post Syndicated from David Honess original https://www.raspberrypi.org/blog/astro-pi-upgrades/

In 2015, The Raspberry Pi Foundation built two space-hardened Raspberry Pi units, or Astro Pis, to run student code on board the International Space Station (ISS).

Astro Pi

A space-hardened Raspberry Pi

Astro Pi upgrades

Each school year we run an Astro Pi challenge to find the next generation of space scientists to program them. After the students have their code run in space, any output files are downloaded to ground and returned to them for analysis.

That download process was originally accomplished by an astronaut shutting down the Astro Pi, moving its micro SD card to a crew laptop and copying over the files manually. This used about 20 minutes of precious crew time.

space pi – Create, Discover and Share Awesome GIFs on Gfycat

Last year, we passed the qualification to allow the Astro Pi computers to be connected to the Local Area Network (LAN) on board the ISS. This allows us to remotely access them from the ground, upload student code and download the results without having to involve the crew.

This year, we have been preparing a new payload to upgrade the operational capabilities of the Astro Pi units.

The payload consists of the following items:

  • 2 × USB WiFi dongles
  • 5 × optical filters
  • 4 × 32GB micro SD cards

Before anyone asks – no, we’re not going outside into the vacuum of space!

USB WiFi dongle

Currently both Astro Pi units are located in the European Columbus module. They’re even visible on Google Street View (pan down and right)! You can see that we’ve created a bit of a bird’s nest of wires behind them.

Astro Pi

The D-Link DWA-171

The decision to add WiFi capability is partly to clean up the cabling situation, but mainly so that the Astro Pi units can be deployed in ISS locations other than the Columbus module, where we won’t have access to an Ethernet switch.

The Raspberry Pi used in the Astro Pi flight units is the B+ (released in 2014), which does not have any built in wireless connectivity, so we need to use a USB dongle. This particular D-Link dongle was recommended by the European Space Agency (ESA) because a number of other payloads are already using it.

Astro Pi

An Astro Pi unit with WiFi dongle installed

Plans have been made for one of the Astro Pi units to be deployed on an Earth-facing window, to allow Earth-observation student experiments. This is where WiFi connectivity will be required to maintain LAN access for ground control.

Optical filters

With Earth-observation experiments in mind, we are also sending some flexible film optical filters. These are made from the same material as the blue square which is shipped with the Pi NoIR camera module, as noted in this post from when the product was launched. You can find the data sheet here.

Astro Pi

Rosco Roscalux #2007 Storaro Blue

To permit the filter to be easily attached to the Astro Pi unit, the film is laser-cut to friction-fit onto the 12 inner heatsink pins on the base, so that the camera aperture is covered.

Astro Pi

Laser cutting at Makespace

The laser-cutting work was done right here in Cambridge at Makespace by our own Alex Bate, and local artist Diana Probst.

Astro Pi

32GB micro SD cards

A consequence of running Earth observation experiments is a dramatic increase in the amount of disk space needed. To avoid a high frequency of commanding windows to download imagery to ground, we’re also flying some larger 32GB micro SD cards to replace the current 8GB cards.

Astro Pi

The Samsung Evo MB-MP32DA/EU

This particular type of micro SD card is X-ray proof, waterproof, and resistant to magnetism and heat. Operationally speaking there is no difference, other than the additional available disk space.

Astro Pi

An Astro Pi unit with the new micro SD card installed

The micro SD cards will be flown with a security-hardened version of Raspbian pre-installed.

Crew activities

We have several crew activities planned for when this payload arrives on the ISS. These include the installation of the upgrade items on both Astro Pi units; moving one of the units from Columbus to an earth-facing window (possibly in Node 2); and then moving it back a few weeks later.

Currently it is expected that these activities will be carried out by German ESA astronaut Alexander Gerst who launches to the ISS in November (and will also be the ISS commander for Expedition 57).

Payload launch

We are targeting a January 2018 launch date for the payload. The exact launch vehicle is yet to be determined, but it could be SpaceX CRS 14. We will update you closer to the time.

Questions?

If you have any questions about this payload, how an item works, or why that specific model was chosen, please post them in the comments below, and we’ll try to answer them.

Thomas and Ed become a RealLifeDoodle on the ISS

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/astro-pi-reallifedoodle/

Thanks to the very talented sooperdavid, creator of some of the wonderful animations known as RealLifeDoodles, Thomas Pesquet and Astro Pi Ed have been turned into one of the cutest videos on the internet.

And RealLifeDoodles aaaaare?

Thanks to the power of viral video, many will be aware of the ongoing Real Life Doodle phenomenon. Wait, you’re not aware?

Oh. Well, let me explain it to you.

Taking often comical video clips, those with a know-how and skill level that outweighs my own in spades add faces and emotions to inanimate objects, creating what the social media world refers to as a Real Life Doodle. From disappointed exercise balls to cannibalistic piles of leaves, these video clips are both cute and sometimes, though thankfully not always, a little heartbreaking.

Our own RealLifeDoodle

A few months back, when Programme Manager Dave Honess, better known to many as SpaceDave, sent me these Astro Pi videos for me to upload to YouTube, a small plan hatched in my brain. For in the midst of the video, and pointed out to me by SpaceDave – “I kind of love the way he just lets the unit drop out of shot” – was the most adorable sight as poor Ed drifted off into the great unknown of the ISS. Finding that I have this odd ability to consider many inanimate objects as ‘cute’, I wanted to see whether we could turn poor Ed into a RealLifeDoodle.

Heading to the Reddit RealLifeDoodle subreddit, I sent moderator sooperdavid a private message, asking if he’d be so kind as to bring our beloved Ed to life.

Yesterday, our dream came true!

Astro Pi

Unless you’re new to the world of the Raspberry Pi blog (in which case, welcome!), you’ll probably know about the Astro Pi Challenge. But for those who are unaware, let me break it down for you.

Raspberry Pi RealLifeDoodle

In 2015, two weeks before British ESA Astronaut Tim Peake journeyed to the International Space Station, two Raspberry Pis were sent up to await his arrival. Clad in 6063-grade aluminium flight cases and fitted with their own Sense HATs and camera modules, the Astro Pis Ed and Izzy were ready to receive the winning codes from school children in the UK. The following year, this time maintained by French ESA Astronaut Thomas Pesquet, children from every ESA member country got involved to send even more code to the ISS.

Get involved

Will there be another Astro Pi Challenge? Well, I just asked SpaceDave and he didn’t say no! So why not get yourself into training now and try out some of our space-themed free resources, including our 3D-print your own Astro Pi case tutorial? You can also follow the adventures of Ed and Izzy in our brilliant Story of Astro Pi cartoons.

Awesome Raspberry Pi cases to 3D print at home

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/3d-printed-raspberry-pi-cases/

Unless you’re planning to fit your Raspberry Pi inside a build, you may find yourself in need of a case to protect it from dust, damage and/or the occasional pet attack. Here are some of our favourite 3D-printed cases, for which files are available online so you can recreate them at home.

TARDIS

TARDIS Raspberry PI 3 case – 3D Printing Time lapse

Every Tuesday we’ll 3D print designs from the community and showcase slicer settings, use cases and of course, Time-lapses! This week: TARDIS Raspberry PI 3 case By: https://www.thingiverse.com/Jason3030 https://www.thingiverse.com/thing:2430122/ BCN3D Sigma Blue PLA 3hrs 20min X:73 Y:73 Z:165mm .4mm layer / .6mm nozzle 0% Infill / 4mm retract 230C / 0C 114G 60mm/s —————————————– Shop for parts for your own DIY projects http://adafru.it/3dprinting Download Autodesk Fusion 360 – 1 Year Free License (renew it after that for more free use!)

Since I am an avid Whovian, it’s not surprising that this case made its way onto the list. Its outside is aesthetically pleasing to the aspiring Time Lord, and it snugly fits your treasured Pi.



Pop this case on your desk and chuckle with glee every time someone asks what’s inside it:

Person: What’s that?
You: My Raspberry Pi.
Person: What’s a Raspberry Pi?
You: It’s a computer!
Person: There’s a whole computer in that tiny case?
You: Yes…it’s BIGGER ON THE INSIDE!

I’ll get my coat.

Pi crust

Yes, we all wish we’d thought of it first. What better case for a Raspberry Pi than a pie crust?

3D-printed Raspberry Pi cases

While the case is designed to fit the Raspberry Pi Model B, you will be able to upgrade the build to accommodate newer models with a few tweaks.



Just make sure that if you do, you credit Marco Valenzuela, its original baker.

Consoles

Since many people use the Raspberry Pi to run RetroPie, there is a growing trend of 3D-printed console-style Pi cases.

3D-printed Raspberry Pi cases

So why not pop your Raspberry Pi into a case made to look like your favourite vintage console, such as the Nintendo NES or N64?



You could also use an adapter to fit a Raspberry Pi Zero within an actual Atari cartridge, or go modern and print a PlayStation 4 case!

Functional

Maybe you’re looking to use your Raspberry Pi as a component of a larger project, such as a home automation system, learning suite, or makerspace. In that case you may need to attach it to a wall, under a desk, or behind a monitor.

3D-printed Raspberry Pi cases

Coo! Coo!

The Pidgeon, shown above, allows you to turn your Zero W into a surveillance camera, while the piPad lets you keep a breadboard attached for easy access to your Pi’s GPIO pins.



Functional cases with added brackets are great for incorporating your Pi on the sly. The VESA mount case will allow you to attach your Pi to any VESA-compatible monitor, and the Fallout 4 Terminal is just really cool.

Cute

You might want your case to just look cute, especially if it’s going to sit in full view on your desk or shelf.

3D-printed Raspberry Pi cases

The tired cube above is the only one of our featured 3D prints for which you have to buy the files ($1.30), but its adorable face begged to be shared anyway.



If you’d rather save your money for another day, you may want to check out this adorable monster from Adafruit. Be aware that this case will also need some altering to fit newer versions of the Pi.

Our cases

Finally, there are great options for you if you don’t have access to a 3D printer, or if you would like to help the Raspberry Pi Foundation’s mission. You can buy one of the official Raspberry Pi cases for the Raspberry Pi 3 and Raspberry Pi Zero (and Zero W)!

3D-printed Raspberry Pi cases



As with all official Raspberry Pi accessories (and with the Pi itself), your money goes toward helping the Foundation to put the power of digital making into the hands of people all over the world.

3D-printed Raspberry Pi cases

You could also print a replica of the official Astro Pi cases, in which two Pis are currently orbiting the earth on the International Space Station.

Design your own Raspberry Pi case!

If you’ve built a case for your Raspberry Pi, be it with a 3D printer, laser-cutter, or your bare hands, make sure to share it with us in the comments below, or via our social media channels.

And if you’d like to give 3D printing a go, there are plenty of free online learning resources, and sites that offer tutorials and software to get you started, such as TinkerCAD, Instructables, and Adafruit.

European Astro Pi: Mission complete

Post Syndicated from David Honess original https://www.raspberrypi.org/blog/european-astro-pi-mission-complete/

In October last year, with the European Space Agency and CNES, we launched the first ever European Astro Pi challenge. We asked students from all across Europe to write code for the flight of French ESA astronaut Thomas Pesquet to the International Space Station (ISS) as part of the Proxima mission.

The winners were announced back in March, and since then their code has been uploaded to the ISS and run in space!

Code from 64 student teams ran between 28 April and 10 May, supervised by Thomas, in the European Columbus module.

Astro Pi on Twitter

We can confirm student programs are finished, results are downloaded from @Space_Station and teams will receive their​ data by next week 🛰️📡

On 10 May the results, data, and log files were downloaded to the ground, and the following week they were emailed back to the student teams for analysis.

Ecole St-André d’E on Twitter

On vient de recevoir les données enregistrées par nos codes #python depuis l’ #iss @CNES @astro_pi @Thom_astro . Reste à analyser tout ça!

We’ve looked at the results, and we can see that many of the teams have been successful in their missions: congratulations to all of you! We look forward to reading your write-ups and blogs.

In pictures

In a surprise turn of events, we learnt that Thomas set up a camera to take regular pictures of the Astro Pi units for one afternoon. This was entirely voluntary on his part and was not scheduled as part of the mission. Thank you so much, Thomas!

Some lucky teams have some very nice souvenirs from the ISS. Here are a couple of them:

Until next time…

This brings the 2016/17 European Astro Pi challenge to a close. We would like to thank all the students and teachers who participated; the ESA Education, Integration and Implementation, Ground Systems, and Flight Control teams; BioTesc (ESA’s user operations control centre for Astro Pi); and especially Thomas Pesquet himself.

Thomas and Russian Soyuz commander Oleg Novitskiy return to Earth today, concluding their six-month stay on the ISS. After a three-hour journey in their Soyuz spacecraft, they will land in the Kazakh steppe at approximately 15:09 this afternoon. You can watch coverage of the departure, re-entry, and landing on NASA TV.

Astro Pi has been a hugely enjoyable project to work on, and we hope to be back in the new school year (2017-18) with brand-new challenges for teachers and students.

Mike Brondbjerg’s Dead Presidents uses Processing to generate portraits.

Processing is a programming language and development environment that sits perfectly at that intersection. It enables you to use code to generate still graphics, animations, or interactive applications such as games. It’s based on the Java programming language, and it runs on multiple platforms and operating systems. Thanks to the work of the Processing Foundation, and in particular the efforts of contributor Gottfried Haider, Processing runs like a champ on the Raspberry Pi.

When I want to communicate how cool Processing is while speaking to members of the Raspberry Pi community, I usually make this analogy: with Sonic Pi, you can use one line of code to make one note; with Processing, you can use one line of code to draw one stroke. Once you’ve figured that out, you can use computational tools such as loops, conditions, and variables to make some beautiful art.

And even though Processing is intended for use in the realm of visual arts, its capabilities can go beyond that. You can make applications that interact with the user through keyboard or mouse input. Processing also has libraries for working with network connections, files, and cameras. This means that you don’t just have to create artwork with Processing. You can also use it for almost anything you need to code.

Physical process

Processing is especially cool on the Raspberry Pi because there’s a library for working with the Pi’s GPIO pins. You can therefore have on-screen graphics interacting with buttons, switches, LEDs, relays, and sensors wired up to your Pi. With Processing, you could build a game that uses a custom controller that you’ve built yourself. Or you could create a piece of artwork that interacts with the user by sensing their proximity to it.

Best of all, Processing was created with learning to code in mind. It comes with lots of built-in examples, and you can use these to learn about many different programming and drawing concepts. The documentation on Processing’s website is very thorough and – as with Raspberry Pi – there’s a very supportive community around it if you run into any trouble. Additionally, the Processing development environment is powerful but also very simplified. For these reasons, it’s perfect for someone who is just getting started.

To get going with Processing on Raspberry Pi, there’s a one-line install command. You can also go to Processing.org and download pre-built Raspbian images with Processing already installed. To help you on your journey, there’s a resource for getting started with Processing. It includes a walkthrough on how to access the GPIO pins to combine physical computing and visual arts.

When you launch Processing, you will see a blank file where you can start keying in your code. Don’t let that intimidate you! All of the world’s greatest pieces of art started off as a raw slab of marble, a blob of clay, or a blank canvas. It just takes one line of code at a time to generate your own masterpiece.

Become a supporter

After this article appeared in The MagPi, the Processing Foundation put out a call for support:

We want you to be a part of this. Our work is almost entirely supported by individual one-time donations from the community. Right now we are outspending what we earn, and we have bigger plans! We want to continue all the work we’re doing and make it more accessible, more inclusive, and more responsive to the community needs.

To create lasting support for these new directions we’re starting a Membership Program. A membership is an annual donation that supports all this work and signifies your belief in it. You can do this as an individual, a studio, an educational institution, or a corporate partner. We will list your name on our members page along with all the others that help make this mission possible.

Sense HAT Emulator Upgrade

Post Syndicated from David Honess original https://www.raspberrypi.org/blog/sense-hat-emulator-upgrade/

Last year, we partnered with Trinket to develop a web-based emulator for the Sense HAT, the multipurpose add-on board for the Raspberry Pi. Today, we are proud to announce an exciting new upgrade to the emulator. We hope this will make it even easier for you to design amazing experiments with the Sense HAT!

What’s new?

The original release of the emulator didn’t fully support all of the Sense HAT features. Specifically, the movement sensors were not emulated. Thanks to funding from the UK Space Agency, we are delighted to announce that a new round of development has just been completed. From today, the movement sensors are fully supported. The emulator also comes with a shiny new 3D interface, Astro Pi skin mode, and Pygame event handling. Click the ▶︎ button below to see what’s new!

Upgraded sensors

On a physical Sense HAT, real sensors react to changes in environmental conditions like fluctuations in temperature or humidity. The emulator has sliders which are designed to simulate this. However, emulating the movement sensor is a bit more complicated. The upgrade introduces a 3D slider, which is essentially a model of the Sense HAT that you can move with your mouse. Moving the model affects the readings provided by the accelerometer, gyroscope, and magnetometer sensors.

Code written in this emulator is directly portable to a physical Raspberry Pi and Sense HAT without modification. This means you can now develop and test programs using the movement sensors from any internet-connected computer, anywhere in the world.

Astro Pi mode

Astro Pi is our series of competitions offering students the chance to have their code run in space! The code is run on two space-hardened Raspberry Pi units, with attached Sense HATs, on the International Space Station.

Astro Pi skin mode

There are a number of practical things that can catch you out when you are porting your Sense HAT code to an Astro Pi unit, though, such as the orientation of the screen and joystick. Just as having a 3D-printed Astro Pi case enables you to discover and overcome these, so does the Astro Pi skin mode in this emulator. In the bottom right-hand panel, there is an Astro Pi button which enables the mode: click it again to go back to the Sense HAT.

The joystick and push buttons are operated by pressing your keyboard keys: use the cursor keys and Enter for the joystick, and U, D, L, R, A, and B for the buttons.

Sense Hat resources for Code Clubs

We also have a new range of Code Club resources which are based on the emulator. Of these, three use the environmental sensors and two use the movement sensors. The resources are an ideal way for any Code Club to get into physical computing.

The technology

The 3D models in the emulator are represented entirely with HTML and CSS. “This project pushed the Trinket team, and the 3D web, to its limit,” says Elliott Hauser, CEO of Trinket. “Our first step was to test whether pure 3D HTML/CSS was feasible, using Julian Garnier’s Tridiv.”

“We added JavaScript rotation logic and the proof of concept worked!” Elliot continues. “Countless iterations, SVG textures, and pixel-pushing tweaks later, the finished emulator is far more than the sum of its parts.”

The finished Sense HAT model: doesn’t it look amazing?

Check out this blog post from Trinket for more on the technology and mathematics behind the models.

One of the compromises we’ve had to make is browser support. Unfortunately, browsers like Firefox and Microsoft Edge don’t fully support this technology yet. Instead, we recommend that you use Chrome, Safari, or Opera to access the emulator.

Where do I start?

If you’re new to the Sense HAT, you can simply copy and paste many of the code examples from our educational resources, like this one. Alternatively, you can check out our Sense HAT Essentials e-book. For a complete list of all the functions you can use, have a look at the Sense HAT API reference here.

Tableau: a generative music album based on the Sense HAT

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/tableau-generative-music-album/

Multi-talented maker Giorgio Sancristoforo has used a Raspberry Pi and Sense HAT to create Tableau, a generative music album. It’s an innovative idea: the music constantly evolves as it reacts to environmental stimuli like atmospheric pressure, humidity, and temperature.

Tableau Generative Album

“There is no doubt that, as music is removed by the phonographrecord from the realm of live production and from the imperative of artistic activity and becomes petrified, it absorbs into itself, in this process of petrification, the very life that would otherwise vanish.”

Creating generative music

“I’ve been dreaming about using portable microcomputers to create a generative music album,” explains Giorgio. “Now my dream is finally a reality: this is my first portable generative LP (PGLP)”. Tableau uses both a Raspberry Pi 2 and a Sense HAT: the HAT provides the data for the album’s musical evolution via its range of onboard sensors.

The Sense HAT was originally designed for use aboard the International Space Station (ISS) as part of the ongoing Astro Pi challenge. It has, however, become a staple within the Raspberry Pi maker community. This is partly thanks to the myriad of possibilities offered by its five onboard sensors, five-button joystick, and 8 × 8 LED matrix.

Limited edition

The final release of Tableau consists of a limited edition of fifty PGLPs: each is set up to begin playing immediately power is connected, and the music will continue to evolve indefinitely. “Instead of being reproduced as on a CD or in an MP3 file, the music is spontaneously generated and arranged while you are listening to it,” Giorgio explains on his website. “It never sounds the same. Tableau creates an almost endless number of mixes of the LP (4 × 12 factorial). Each time you will listen, the music will be different, and it will keep on evolving until you switch the power off.”

Experiment with the Sense HAT

What really interests us is how the sound of Tableau might alter in different locations. Would it sound different in Cambridge as opposed to the deserts of Mexico? What about Antarctica versus the ISS?

If Giorgio’s project has piqued your interest, why not try using our free data logging resource for the Sense HAT? You can use it to collect information from the HAT’s onboard sensors and create your own projects. How about collecting data over a year, and transforming this into your own works of art?

Even if you don’t have access to the Sense HAT, you can experience it via the Sense HAT desktop emulator. This is a great solution if you want to work on Sense HAT-based projects in the classroom, as it reduces the amount of hardware you need.

If you’ve already built a project using the Sense HAT, make sure to share it in the comments below. We would love to see what you have been making!

European Astro Pi Challenge winners

Post Syndicated from David Honess original https://www.raspberrypi.org/blog/european-astro-pi-winners/

In October last year, with the European Space Agency and CNES, we launched the first ever European Astro Pi challenge. We asked students from all across Europe to write code for the flight of French ESA astronaut Thomas Pesquet to the International Space Station (ISS) as part of the Proxima mission. Today, we are very excited to announce the winners! First of all, though, we have a very special message from Thomas Pesquet himself, which comes all the way from space…

Thomas Pesquet congratulates Astro Pi participants from space

French ESA astronaut Thomas Pesquet floats in to thank all participants in the European Astro Pi challenge. In October last year, together with the European Space Agency, we launched the first ever European Astro Pi challenge for the flight of French ESA astronaut Thomas Pesquet to the International Space Station (ISS) as part of mission Proxima.

Thomas also recorded a video in French: you can click here to see it and to enjoy some more of his excellent microgravity acrobatics.

A bit of background

This year’s competition expands on our previous work with British ESA astronaut Tim Peake, in which, together with the UK Space Agency and ESA, we invited UK students to design software experiments to run on board the ISS.

In 2015, we built two space-hardened Raspberry Pi units, or Astro Pis, to act as the platform on which to run the students’ code. Affectionately nicknamed Ed and Izzy, the units were launched into space on an Atlas V rocket, arriving at the ISS a few days before Tim Peake. He had a great time running all of the programs, and the data collected was transmitted back to Earth so that the winners could analyse their results and share them with the public.

The European challenge provides the opportunity to design code to be run in space to school students from every ESA member country. To support the participants, we worked with ESA and CPC to design, manufacture, and distribute several hundred free Astro Pi activity kits to the teams who registered. Further support for teachers was provided in the form of three live webinars, a demonstration video, and numerous free educational resources.

The challenge

Thomas Pesquet assigned two missions to the teams:

  • A primary mission, for which teams needed to write code to detect when the crew are working in the Columbus module near the Astro Pi units.
  • A secondary mission, for which teams needed to come up with their own scientific investigation and write the code to execute it.

The deadline for code submissions was 28 February 2017, with the judging taking place the following week. We can now reveal which schools will have the privilege of having their code uploaded to the ISS and run in space.

The proud winners!

Everyone produced great work and the judges found it really tough to narrow the entries down. In addition to the winning submissions, there were a number of teams who had put a great deal of work into their projects, and whose entries have been awarded ‘Highly Commended’ status. These teams will also have their code run on the ISS.

We would like to say a big thank you to everyone who participated. Massive congratulations are due to the winners! We will upload your code digitally using the space-to-ground link over the next few weeks. Your code will be executed, and any files created will be downloaded from space and returned to you via email for analysis.

FAQ

Why aren’t all 22 ESA member states listed?

  • Because some countries did not have teams participating in the challenge.

Why do some countries have fewer than five teams?

  • Either because those countries had fewer than five teams qualifying for space flight, or because they had fewer than five teams participating in the challenge.

How will I get my results back from space?

  • After your code has run on the ISS, we will download any files you created and they will be emailed to your teacher.

JavaWatch automated coffee replenishment system

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/javawatch-automated-coffee-replenishment-system/

With the JavaWatch system from Terren Peterson, there’s (Raspberry Pi) ZERO reason for you ever to run out of coffee beans again!

By utilising many of the Amazon Web Services (AWS) available to budding developers, Terren was able to create a Pi Zero-powered image detection unit. Using the Raspberry Pi Camera Module to keep tabs on your coffee bean storage, it automatically orders a fresh batch of java when supplies are running low.

JavaWatch Sales Pitch

Introducing JavaWatch, the amazing device that monitors your coffee bean supply and refills from Amazon.com.

Coffee: quite possibly powering Pi Towers’ success

Here at Pi Towers, it’s safe to say that the vast majority of staff members run on high levels of caffeine. In fact, despite hitting ten million Pi boards sold last October, sending two Astro Pi units to space, documenting over 5,000 Code Clubs in the UK, and multiple other impressive achievements, the greatest accomplishment of the Pi Towers team is probably the acquisition of a new all-singing, all-dancing coffee machine for the kitchen. For, if nothing else, it has increased the constant flow of caffeine into the engineers…and that’s always a positive thing, right?

Here are some glamour shots of the beautiful beast:

Anyway, back to JavaWatch

Terren uses the same technology that can be found in an Amazon Dash button, replacing the ‘button-press’ stimulus with image recognition to trigger a purchase request.

JavaWatch flow diagram

Going with the JavaWatch flow… 
Image from Terren’s hackster.io project page.

“The service was straightforward to get working,” Terren explains on his freeCodeCamp blog post. “The Raspberry Pi Camera Module captures and uploads photos at preset intervals to S3, the object-based storage service by AWS.”

The data is used to calculate the amount of coffee beans in stock. For example, the jar in the following image is registered at 73% full:

A jar which is almost full of coffee beans

It could also be 27% empty, depending on your general outlook on life.

A second photo, where the beans take up a mere 15% or so of the jar, registers no beans. As a result, JavaWatch orders more via a small website created specifically for the task, just like pressing a Dash button.

JavaWatch DRS Demo

Demonstration of DRS Capabilities with a project called JavaWatch. This orders coffee beans when the container runs empty.

Terren won second place in hackster.io’s Amazon DRS Developer Challenge for JavaWatch. If you are in need of regular and reliable caffeine infusions, you can find more information on the build, including Terren’s code, on his project page.
