Rejoice! It’s time for a new issue of Hackspace magazine, packed with things for you to make, build, hack, and create!

HackSpace magazine issue 9

Tools: they’re what separates humans from the apes! Whereas apes use whatever they find around them to get honey, pick pawpaws, and avoid prickly pears, we humans take the step of making things with which to make other things. That’s why in this issue of HackSpace magazine, we look at 50 essential tools to make you better at making (and by extension better at being a human). Take a look, decide which ones you need, and imagine the projects that will be possible with your shiny new stuff.

Konichiwakitty

In issue 9, we feature Konichiwakitty, known as Rachel Wong to her friends, who is taking the maker world by storm with her range of electronic wearables.

Alongside making wearables and researching stem cells, she also advocates for getting young people into crafting, including making their own wearables!

Helping

Remap is a fantastic organisation. It’s comprised of volunteer makers and builders who use their skills to adapt the world and build tech to help people with disabilities. Everyone in the maker community can do amazing stuff, and it’s wonderful that so many of you offer your time and skills for free to benefit people in need.

Music

The band Echo and the Bunnymen famously credited a drum machine as a band member, and with our tutorial, you too can build your own rhythm section using a Teensy microcontroller, a breadboard, and a few buttons.

And if that’s not enough electro beats for you, we’ve also got a guide to generating MIDI inputs with a joystick — because keyboards and frets are so passé.

Pi Wars

Having shiny new stuff on its own isn’t enough to spur most people to action. No, they need a reason to make, for example total mechanical dominance over their competitors. Offering an arena for such contests is the continuing mission of Tim Richardson, who along with Mike Horne created Pi Wars.

In its five-ish years, Pi Wars has become one of the biggest events on the UK maker calendar, with an inspired mix of robots, making, programming, and healthy competition. We caught up with Tim to find out how to make a maker event, what’s next for Pi Wars, and how to build a robot to beat the best.

Fame

Do you ever lie awake at night wondering how many strangers on the internet like you? If so (or if you have a business with a social media presence, which seems more likely), you might be interested in our tutorial for a social media follower counter.

This build takes raw numbers from the internet’s shouting forums and turns them into physical validation, so you can watch your follower count increase in real time as you shout into the void about whether Football’s Coming Home. 

And there’s more…

In this issue, you can also:

• See how to use the Google AIY Projects Vision kit to turn a humble water pistol into a single-minded dousing machine that doesn’t feel pity, fear, or remorse
• Find out how to make chocolate in whatever shape you want
• Learn from a maker who put 20 hours work into a project only to melt her PCBs and have to start all over again (spoiler alert: it all worked out in the end)

All this, plus a bunch of reviews and many, many more projects to dig into, in Hackspace magazine issue 9.

In our latest resource, we show you how to create a website and use it to document your coding projects.

Why document your code?

Search the web with the right key words for your programming conundrum, and you’re bound to find someone who has written software to address a question that’s at least similar to yours. And not only that, they’re also making their software freely available under an open source license, and writing documentation to help you use their code. How awesome it that?!

Many people who write code are eager to share their programs and allow others to use and remix them according to their own needs. This is why the open source community is so inviting for makers, especially those who want to make projects that are yet beyond their ability to build from scratch.

So unless you plan on turning your code into a money-making commodity, you’re writing scripts that you can share with others. By adding clear, supporting online documentation to your code, you’ll help people all over the world to not only use your software but to also understand what everything does and become better programmers themselves.

Our resource

In our latest resource, we show you how to use docstrings to automatically create documentation for your Python code. Then, we walk you through using Sphinx to build a website showcasing this documentation and any example scripts you want to share with the world.

You’ll learn how to create supporting documentation to guide users through elements of your code, add multiple pages to your website, and use themes to costumise the site’s layout and make it stand out.

You can find the resource here, and our full list of free resources here on our projects site.

More free resources

We’ve also recently released a new Sense HAT music player project, along with a resource teaching basic Raspberry Pi terminal navigation skills with a fun game to find all the Pac-Man ghosts.

The sun is actually shining here in Cambridge, and with it, summer-themed Raspberry Pi projects are sprouting like mushrooms across our UK-based community (even though mushrooms don’t like hot weather…). So we thought we’d gather some of our favourite Pi-powered projects perfect for the sun-drenched outdoors.

Air quality monitors and solar radiation

With the sun out in all its glory, we’re spending far more time outside than is usual for UK summer. To protect yourself and your adventurous loved ones, you might want to build a Raspberry Pi device to monitor solar radiation.

“Solar radiation is the radiation, or energy, we get from the sun.” explains project designer Uladzislau Bayouski. “Measurements for solar radiation are higher on clear, sunny day and usually low on cloudy days. When the sun is down, or there are heavy clouds blocking the sun, solar radiation is measured at zero.”

To measure more health-related environmental conditions, you could build this air quality monitor and keep an eye on local pollution.

Maker Oliver Crask describes the project:

Data is collected by the particulates sensor and is combined with readings of temperature, humidity, and air pressure. This data is then transferred to the cloud, where it is visualised on a dashboard.

If you’ve been building your own hackable weather station using our free guide, these are also great add-ons to integrate into that project.

Automatic pet and plant feeders

While we’re spending our days out in the sun, we need to ensure that our pets and plants are still getting all the attention they need.

This automatic chicken feeder by Instructables user Bertil Vandekerkhove uses a Raspberry Pi to remotely control the release of chicken feed. No more rushing to get home to feed your feathered friends!

And while we’re automating our homes, let us not forget the plants! iPlanty is an automated plant-watering system that will ensure your favourite plant babies get all the moisture they need while you’re away from your home or office.

Planty Project

An automated Plant watering solution that waters my plant every day at 8:30

Electromagnetic bike shed lock

If, like me, you live in constant fear that your beloved bike may be stolen, this electromagnetic bike shed lock is the solution you need.

The lock system allows for only one user per lock at any one time, meaning that your bike needs to be removed before anyone else can use their RFID card to access the shed.

Time-lapse cameras

With so much sunlight available, now is the perfect time to build a time-lapse camera for your garden or local beauty spot. Alex D’s Zero W time-lapse HAT allows for some glorious cinematic sliding that’s really impressed us.

Slider Test Sunset

Slider settings: -960 mm drive distance -400 steps -28 seconds interval Camera settings (Canon EOS 550D): – Magic Lantern auto ettr – max ISO 1600 – max Exposure 10 seconds

If you don’t think you can match Alex’s PCB milling skills, you can combine our free Raspberry Pi timelapse resource and Adafruit’s motorised camera slider for a similar project!

Infrared laser tag

While it’s sunny and warm, why not make this Raspberry Pi Zero W laser tag for the kids…

…and then lock them outside, and enjoy a Pimms and a sit-down in peace. We’re here for you, suffering summer holiday parents. We understand.

Self-weighing smart suitcase

“We’re all going on a summer holiday”, and pj_dc’s smart suitcase will not only help you track of your case’s location, it’ll also weigh your baggage.

Four 50kg load cells built into the base of the case allow for weight measurement of its contents, while a GPS breakout board and antenna let you track where it is.

Our free resources

While they’re not all summer-themed, our free Raspberry Pi, Code Club, and CoderDojo resources will keep you and your family occupied over the summer months whenever you’ve had a little too much of the great outdoors. From simple Scratch projects through to Python and digital making builds, we’ve got something for makers of all levels and tastes!

If you’re new to Raspberry Pi, begin with our Getting started guide. And if you’re looking for even more projects to try, our online community shares a sea of tutorials on Twitter every week.

Raspberry Pis? Check. Iconic phoneboxes? Check. Whisky? Check, check, check. Find out how Bright Signals incorporated all three for the launch of the latest range of Jura whisky.

Jura whisky from Jura

When Jura, a distillery on the Scottish island of Jura — population 200 — wanted to promote their new range of whisky, they and creative agency Punk decided to install a series of phoneboxes on the island that tell the stories of locals.

Grant Gibson, Bright Signals’ Deputy Managing Director, has taken the time to explain the process of retrofitting UK pay phones with Raspberry Pis. Here’s a brief time-lapse of the process:

Building phones for Jura

In June 2018 I built three custom pay phones for Jura Whisky. You can read all about the build here.

Retrofitting phoneboxes

The process wasn’t as easy as the video would have you believe — Grant met a series of bumps in the road along the way.

I started by buying a standard UK pay phone. Made by Solitaire, it’s the kind of vandal-proof steel unit you might find in a shopping centre or airport. The good news is that it looked the part and was really sturdy. The bad news is that the whole inside of the phone was a single PCB, with everything from the LCD display to the on-hook sensor surface mounted.

Eventually, Grant decided to remove the PCB entirely and rebuild the innards using an Adafruit Membrane Keypad, a Raspberry Pi, and a Pimoroni Display-O-Tron.

Motion sensor–triggered phone calls

“I mounted a Raspberry Pi to act as the brains of the device,” explains Grant. “The on-board sound from the headphone port does double duty, providing both the sound heard through the handset and the incoming ringtone, which is in turn triggered by a PIR sensor; the phone automatically starts ringing whenever anyone walks past the phone box.”

The phone boxes will go on tour across the UK and the rest of the world, so if you’d like to see them in person, and try some Jura whisky, keep your eye on the Jura Twitter account.

For more information on the project, visit Grant’s website. And while you’re there, be sure to check out Bright Signal’s other Raspberry Pi-based builds: the bicycle-powered beer dispenser for Menabrea, the Magners #6Stringer guitar built of cans, and Rude-olf, the animatronic reindeer.

The end of the academic year is here, and we are marking the occasion by celebrating teachers from all over the world.

For those about to teach, we salute you.

Since last September, we’ve run a whole host of programmes that teachers have been involved in. From training with us at Picademy to building apocalyptic projects for Pioneers, from running Code Clubs, Dojos, and Raspberry Jams to learning tea-making algorithms on our free online training courses, these brilliant people do amazing things on a daily basis. And even more amazingly, they somehow also have the energy to take their knowledge into schools and share it with their learners to get them excited about computing too.

Dr Sue Sentance, the Raspberry Pi Foundation’s new Chief Learning Officer, has trained teachers for many years and understands better than most the impact a good teacher can have:

“When thinking about teaching Computing, we often get so caught up in the technology — what software, what kit, what environment, etc. — that we forget that it’s the teachers who actually facilitate students’ learning and inspire and motivate the students. A passionate and enthusiastic teacher is more important than which device or tool the students are using, because they understand what will help their students. “

In celebration of our education community, we asked teachers around the world to answer one big question:

“What has been your computing highlight of the year?”

Caroline Keep

Caroline (top right) and her group of students at Spark Penketh

Caroline Keep won the TES New Teacher of the Year award and runs Spark Penketh, a school makerspace in Warrington. She will also be training with us in August to become a Raspberry Pi Certified Educator. Her highlight of the year was achieving success at the forefront of the UK’s makerspace movement:

“All the physical computing projects we’ve done since February when Raspberry Pi co-founder Pete Lomas opened our school makerspace (the first one in a UK state school) have been amazing! We’ve built and coded talking robots, and gesture-controlled ones on micro:bits with primary schools. We’ve built drones, coded Arduinos for European Maker Week, opened a RoboDojo, used Python and Node-RED on Raspberry Pi to control weather stations, Pi Camera Modules, and robots, and we’ve designed a Digital Creative pathway for Industry 4.0 skills for September. Next up are Google AIY Projects kits, Redfern Electronic’s Crumble, and Bare Conductive’s Touch Board. We can’t wait!”

Heidi Baynes

Heidi (left) and two other amazing US-based educators pose under a very apt sign. It’s like they planned it.

Heidi Baynes is an Education Coordinator for the County Office of Education in Riverside, California. Her highlight is a birthday party with a difference:

“The Riverside Raspberry Jam was held on 3 March 2018 as part of Raspberry Pi’s Big Birthday celebration. Fellow Picademy graduate Ari Flewelling and I planned the event in conjunction with Vocademy, and we were thrilled by the overwhelming support from the local community. The event featured a project showcase, workshops, and an introduction to all things Raspberry Pi. We can’t wait to start planning the 2019 Riverside Raspberry Jam! I was also particularly proud of the students from Mountain Heights Academy who shared their Raspberry Pi and micro:bit projects at the Consortium’s #CSforAll event in Riverside. Our student Hailey was able to share her experiences as part of a student panel and even had the opportunity to meet the CEO of code.org, Hadi Partovi!”

Amy Bloodworth

Amy Bloodworth and her Astro Pi–winning students

Amy Bloodworth is a teacher at The American School In Switzerland (TASIS) in Lugano, Switzerland. Her highlight is literally out of this world:

“It has been a busy year for us here in Switzerland. Highlights for me and my students include meeting a computer game designer, competing in the World Robot Olympiad, and participating in the Astro Pi Challenge. With Astro Pi, my students loved that they could send their coded message to the ISS astronauts in any of the languages of ESA. As we are an international school, so this helped the students feel more connected to the task. The Astro Pi Challenge hooked the students in and acted as a springboard for other activities, such as coding an ISS tracker that alerted them when the ISS was overhead, and other science experiments using the Sense HAT. Next year, I plan to start a new after-school club dedicated to competitive robotics.”

Janice Paterson

Janice Paterson’s lovely class of brain-eating zombies

Janice Paterson is the Principal Teacher at Wormit Primary in Fife, Scotland. Her highlight wouldn’t seem out of place in The Walking Dead:

“We loved the amazing open-ended challenge of a zombie apocalypse, courtesy of Raspberry Pi’s Pioneers programme. It was truly cross-curricular and completely immersive for all the young learners. The books were devoured for information/ideas, and the makeup kits inspired our imaginations and creative side. We had Pi-powered, zombie-detecting robots coded to offer assorted challenges, and micro:bits set up as zombie teacher detectors (their thermometers were used because, of course, teachers have hot bodies!). We all learned loads! The best bit was sharing it all with the rest of our Code Club and the whole school.”

Wojtek Zielinski

Our Code Club resources translated into Polish

Wojtek Zielinski works in Poland as a teacher. His highlight was a breakthrough he had when working with the translated versions of our resources with his students:

“When children work with resources in English, they often end up following what’s in the pictures. They don’t understand why the game or the program they created works. Translated materials enable them to truly learn and understand programming concepts, and that empowers them to experiment and create more. Translations are therefore essential for learning.”

Our thanks

We are so grateful for everything our teachers do to help us make our programmes a success. Together we’ll be able to achieve our goal of making high-quality computing resources that are accessible to everyone!

As a quick aside, you might also be interested to read a recent article written by Raspberry Pi creator and co-founder Eben Upton about the positive impact his teachers had on him.

Whether you’re a teacher wanting to share your success, or you simply want to share your appreciation for the teachers who inspired you, tell us about it in the comments below.

And from everyone at the Raspberry Pi Foundation, there’s only one thing left to say…

Teachers, we salute you!

Raspberry Fields forever

On 30 June and 1 July, our community of makers, vendors, speakers, volunteers, and drop-in activity leaders impressed over 1300 visitors who braved the heat to visit our festival of digital making at Cambridge Junction.

Our mini festival was both a thank you to our wonderful community and a demonstration of the sheer scale of support and ideas we offer to people looking to get involved in digital making for the first time.

Projects and talks galore

Our community of makers came out in force at Raspberry Fields, with shops, hands-on activities, installations, and show-and-tells demonstrating some of the coolest stuff you can do with a Raspberry Pi and with digital making in general.

Many visitors we spoke to couldn’t believe some of the incredible creations and projects our community members had brought along for them to learn about and play with.

Over the weekend, we had 29 talks on two stages, with our community speakers coming from all over the UK, as well as France, Germany, Korea, Japan, and Australia! Their talks covered a fascinating range of topics such as volunteering with our coding clubs, digital inclusion, drones, wildlife conservation, and so much more! If you missed any of the speakers, don’t worry: we will be uploading talks to our Youtube channel for everyone to see.

Spectacular live shows

We rounded off the two days with three smashing performances: on Saturday, the fantastic Neil Monteiro showed off some of the awesome things you can do with an Astro Pi at home. He was followed by the outstanding Ada.Ada.Ada., in which Ada Lovelace, kitted out in an epic tech-covered dress, taught people all about her programming legacy.

Sunday’s finale brought the mischief of Brainiac Live! to Raspberry Fields: the Brainiacs showed us just how much they laugh in the face of science, before providing us with the explosive finish every good festival needs!

Outstanding volunteers

A whopping 60 community members came and helped us out, many of whom had never volunteered at a Raspberry Pi event before! Our festival of digital making would not have happened without these lovely people willing to give up some of their precious weekend to ensure that everything went off without a hitch.

The volunteers were doing everything from greeting and registering guests as they arrived, handing out swag bags, and stamping bingo cards, to giving directions, helping out with activities, and managing our two stages. They were absolutely fantastic, and we hope to see them all again at future events!

Join our community today

Raspberry Fields was just a taster of what is going on around the world every day within the marvellous Raspberry Pi community at Raspberry Jams, Code Clubs, CoderDojos, Coolest Projects events, or at home, where people use our products and free resources to create their own projects. If our festival has made you curious, then dive in and join the amazing people that have made it possible!

Till next time!

The whole Raspberry Pi team is hugely grateful to all our community members who helped out in some way with Raspberry Fields, as well as to all the staff at Cambridge Junction, who were so open and friendly, and happy to let us taking over the whole venue for a weekend. We would like to say a massive thank you for making the event so much fun for everyone involved, and for being so welcoming to everyone who took part!

We look forward to seeing all of you at upcoming events!

Relive the San Andreas glory days with this Grand Theft Auto radio built by Raphaël Yancey.

Raphaël Yancey on Twitter

With the “tuned” status LED. https://t.co/PuIi6sY78V

…and now I have Barracuda stuck in my head.

The music of GTA

Anyone who has played Grand Theft Auto knows that one of the best parts of the series is the radio stations: a mix of classic tunes and often comical DJ interludes make driving haphazardly through the streets of San Andreas a joy.

And much like fans of the Fallout series, many of us GTA players are guilty of listening to the in-game music outside of gaming sessions.

Hacking a radio

Maker Raphaël Yancey loves the San Andreas tunes so much, he decided to build his own Grand Theft Auto radio, complete with the MP3s available from Rockstar, the game’s creators.

Raphaël used a 1970s Optalix TO100 portable radio for this project, along with a Raspberry Pi 3. While this would be enough to create a music player, he also added two potentiometers for volume control and frequency tuning, as shown in the video above.

Python code allows the potentiometers to move within a virtual frequency range of 88.7Mhz to 108.0Mhz, with five stations to find along the way. A LED comes on whenever the player finds a station, and the Pi then plays the music.

You can find Raphaël’s complete code for building your own GTA radio here. We’re keen to see what other game-based music projects our community will come up with. Here at Pi Towers, we have a spare Fallout Pip-Boy that’s aching to play the sweet sounds of the post-apocalyptic Commonwealth…

Raspberry Pi and music

The integration of Raspberry Pi within music projects is a theme we’re very fond of. From rejuvenated jukeboxes such as Tijuana Rick’s 1960’s Wurlitzer, to The Nest, a USB music download system built into Table Mountain, we’ve seen a host of imaginative projects and are always eager to discover more.

So if you’ve used a Raspberry Pi in your music project, whether it be a jukebox, a guitar pedal, or an instrument, be sure to share it with us.

Last year, Code Club Australia set a new world record during their Moonhack event for the most young people coding within 24 hours. This year, they’re hoping to get 50000 kids involved — here’s how you can take part in this interstellar record attempt!

Celebrating the Apollo 11 moon landing

Nearly 50 years ago, humankind took one giant leap and landed on the moon for the first time. The endeavour involved an incredible amount of technological innovation that, amongst other things, helped set the stage for modern coding.

To celebrate this amazing feat, Code Club Australia are hosting Moonhack, an annual world record attempt to get as many young people as possible coding space-themed projects over 24 hours. This year, Moonhack is even bigger and better, and we want you to take part!

Moonhack past and present

The first Moonhack took place in 2016 in Sydney, Australia, and has since spread across the globe. More than 28000 young people from 56 countries took part last year, from Syria to South Korea and Croatia to Guatemala.

This year, the aim is to break that world record with 50000 young people — the equivalent of the population of a small town — coding over 24 hours!

Get involved

Taking part in Moonhack is super simple: code a space-themed project and submit it on 20 July, the anniversary of the moon landing. Young people from 8 to 18 can take part, and Moonhack is open to everyone, wherever you are in the world.

The event is perfect for Code Clubs, CoderDojos, and Raspberry Jams looking for a new challenge, but you can also take part at home with your family. Or, if you have access to a great venue, you could also host a Moonhackathon event and invite young people from your community to get involved — the Moonhack team is offering online resources to help you do this.

On the Moonhack website, you’ll find four simple, astro-themed projects to choose from, one each for Scratch, Python, micro:bit, and Gamefroot. If your young coders are feeling adventurous, they can also create their own space-themed projects: last year we saw some amazing creations, from a ‘dogs vs aliens’ game to lunar football!

For many young people, Moonhack falls in the last week of term, so it’s a perfect activity to celebrate the end of the academic year. If you’re in a part of the world that’s already on break from school, you can hold a Moonhack coding party, which is a great way to keep coding over the holidays!

To register to take part in Moonhack, head over to moonhack.com and fill in your details. If you’re interested in hosting a Moonhackathon, you can also download an information pack here.

Rumour has it that there’s a worldwide football tournament on, and that England, surprisingly, are doing quite well. In celebration, here are some soccer-themed Raspberry Pi projects for you to try out at home between (or during) matches.

FutureLearn Football

Uploaded by Raspberry Pi on 2018-07-09.

Beat the goalie

Score as many goals as you can in 30 seconds with our code-it-yourself Beat the Goalie game for Scratch. You can access Scratch in any web browser, or offline with your Raspberry Pi.

Start by coding a moving football in Scratch, and work through the project to build a game that tallies your successful attempts on goal within a time limit that you choose. Up the stakes by upgrading your game to include second-player control of the penguin goalie.

Table football

Once you’ve moved on from penalty practice, it’s time to recruit the whole team!

Our Table Football project – free, like all of our learning projects – comes with all the ingredients you need to recreate the classic game, including player sprites, graphics, and sounds.

Instant replay!

Scratch is all well and good, but it’s time we had some real-life table football, with all the snazzy upgrades you can add using a Raspberry Pi.

Foosball Instant Replay

Demo of Foosball Instant Replay system More info here: * https://ift.tt/29ac7ae * https://ift.tt/292fkoR Music: https://ift.tt/TRXbBv

Stefan Wehner’s build is fully documented, so you can learn how to add automatic goal detection, slow-motion instant replay, scorekeeping, tallying, and more.

Ball tracking with Marty

Marty is a 3D-printable educational robot powered by a Raspberry Pi. With the capacity to add the Raspberry Pi camera module, Marty is a great tool for practising object tracking – in this case, ball tracking – for some football fun with robots!

Teaching Marty the Robot to Play Football

In this video we start to program Marty The Robot to play football, using a camera and Raspberry Pi on board to detect the ball and the goal. With the camera, Marty can spot a ball, and detect a pattern next to the goal.

You can also check out Circuit Digest’s ball-tracking robot using a Raspberry Pi, and this ball tracking tutorial by amey_s on Instructables.

I know: you’ve seen a bajillion RetroPie implementations before, and a bajillion casemods to go with them. But this one’s so hopelessly, magnificently splendid that we felt we had to share. Magnetic levitation. It’s not just for trains and frogs.

This Zelda casemod, covered with engraved pine from the forests of Hyrule and shiny brass mouldings hammered by…dwarves or something, would be gorgeous as-is. The levitating, mirrored Triforce twizzling away on top is the icing on the cake; and a very lovely cake it is too. Here’s some video (in Spanish, with English subtitles) from Tuberviejuner in Spain, walking you through the build.

Raspberry pi Zelda mod: MagicBerry WindWaker by Makomod & Tuberviejuner.

Raspberry pi Zelda mod: Magic Berry WindWaker The Legend of Zelda by Makomod & Tuberviejuner alucinad con el triforce levitador.

This magical piece of work is by MakoMod, a case modder who splits his time between Barcelona and Texas. There’s a Pi inside running RetroPie, and a separate electromagnetic device levitating the Triforce up top. If you’re interested in incorporating something like this into one of your own builds, there are two ways to go: make your own from scratch, as DrewPaul Designs has done here, or buy a pre-built kit.

If you get in there quickly, you’ve a chance to own this one-off case: MakoMod is auctioning it on eBay. You’ve got until July 14 2018 to bid – good luck!
