2019/5/24 20:20	Raspberry Pi » Blog	Liverpool MakeFest \| HackSpace magazine #19 The news that UK Maker Faire was to shut its doors came as a bit of a surprise to many. This vibrant weekend of makers meeting, sharing, and learning was absolutely brilliant, and left us fizzing with ideas after our visits there. We’re sad that it’s gone. Makers being makers though, if there’s demand, it will be filled. And that’s exactly what’s happening in Liverpool with Liverpool MakeFest. On 29 June 2019, the MakeFest will hold its fifth iteration. This is the UK’s biggest free maker event, attracting thousands of visitors, and its vision of a free, maker-focused festival is spreading far and wide. We visited the mid-Victorian splendour of Liverpool Central Library, the home of MakeFest, to talk to the founders — Denise Jones, Mark Feltham, and Caroline Keep — to find out what makes this event special. Liverpool MakeFest 2019 is taking place at the Central Library, Saturday 29 June 2019, and it’s completely free to attend HackSpace magazine: Hello! Thanks for having us over here. How did the three of you come together to start Liverpool MakeFest? Caroline Keep: I was a geotechnical engineer, Mark’s an academic, and Denise is a librarian. We bumped into each other watching a workshop in lantern making. Mark had all the academic experience. When I came to work with Mark on his makerspace, I was the geeky maker — he didn’t even have a smartphone at that time. I got the education bug and then moved into secondary school teaching. Mark Feltham: It all started over there, as a chance meeting. We bumped into each other and got chatting. Within six weeks, we’d filled the library. We thought it would be a one-off, but since then it’s taken off. Caroline is the reigning TES New Teacher Of The Year HS: So no business plan, no franchising fees, no world domination? CK: We’ve just winged it. We made all the banners, bunting. The first year my PGCE fund paid for MakeFest! This building reopened again in 2013, and in 2014 we were lucky that they were running a programme of events and initiatives to make it a really vibrant building, so it was the right time as well. We thought we’d have a little room off to the side and get maybe six tables. We’d already done a Mini Maker Faire, and we’ve always been good friends with [local makerspace] DoES Liverpool, so we were confident we’d get at least a few people turning up. And in six weeks we were full. MF: We pulled the first one off, we’re talking the first three floors of the library and 60 makers, for £850. And that included feeding them and making badges as well. One of the spin-offs that have come out of MakeFest is Little Sandboxes, which takes making out to deprived areas of the city HS: For context, this building is huge. It’s bigger than most libraries; it’s probably about the same size as the Life Centre in Newcastle, where UK Maker Faire was held until recently. It must have helped to have a librarian on board to negotiate with the powers that be? Denise Jones: I had to sell it to the people in charge back then, which were the head of service and the manager of this building. The Department for Culture, Media and Sport has a Taskforce for Libraries, which is funded until next year. We’re close to finishing the national guidance now for the Taskforce — the idea is to get one of these [MakeFests] in every library. We wanted the guidance doc to be inclusive of museums and libraries, because we knew that Manchester had opted to put their MakeFest in a museum. We’ve got Chester and Stoke MakeFest, and there’s one in the pipeline in Wrexham. We were having the same conversations over and over again, so we decided to write a document: how to run a MakeFest. Liverpool Central Library was renovated a few years ago — the precious books went into temporary storage in a salt mine in Cheshire to keep them dry HS: What have we got to look forward to this year and beyond? CK: That’s a good question. We’ve got some corking stuff coming this year. We’ve given it the theme ’Space and time – creativity in the making’. We’ve got events planned for the Apollo anniversary, and [just] before MakeFest we’re going to kick off with a music day, showing people how to make music, and making the instruments to make music. That’s another spin-off that’s come out of MakeFest: the MakerNoise Unconference at Edge Hill University. MF: We’ve always felt that we hold MakeFest in trust for makers. In terms of where it goes long-term, I don’t see it ever becoming more than a one-day event here, because one day is good. It gives people Sunday to get over things, and get home because they have day jobs on a Monday. We’re always very sensitive to that, we don’t want to take up too much of people’s time. The other thing is that I don’t see it spilling out into a bigger building; it’s always going to be in the library. But the way to grow it is to put it in other libraries. Not to make this one, Liverpool, bigger and take over. Then each maker community gets its own feel, and its own vibe — Stoke MakeFest has a very different feel to ours, because their maker scene is different to ours, and their city is different to ours. The other way to expand it is that, rather than by just expanding to other cities, you can have more events on throughout the year. Rather than being solely a one-day event, you can have all these spin-offs, so once a month there’s something going on. Rather than it just being about tech and digital, we’ve always liked to have some sort of fantasy element. Things like Doctor Who, Star Wars, Darth Vader, K-9 — the kids love that. We have a lot of friends who are into steampunk; they get roped in to do front-of-house duties. You know what the funny thing was at the first one? Not only did the public enjoy it, but also the makers. It’s kind of like a musician playing an acoustic set. We’ve got a get-together on the Thursday before, we’ve got a Friday night party going, we always do an after-party. The public come on the Saturday, but there’s always stuff going on that week for makers. In addition to always wanting it to be free for the public, and for the makers to not have to pay for their stand, we feel very strongly that we should give something back. We always give them lunch, we always give them a badge, and there’s always a party. We can’t pay them, but it’s our way of showing our appreciation to the makers who come and make it what it is. The celebration and sharing are big parts of the maker ethos. People like to show [their projects] not to show off, not to say ‘Look at how clever I am’ — it’s more to say ‘Look at this awesome thing, isn’t this cool?’ Trying to explain that to people can be tricky. You can make this: here’s how you do it. That’s the ethos. CK: I always feel with MakeFest — you said it’s like an acoustic gig. I always envisioned it as Liverpool’s party for makers. It’s our little get-together, and that’s how I like it. Read the full interview in HackSpace magazine issue 19, out now!

2019/5/23 21:13	Raspberry Pi » Blog	Make a Donkey Kong–style walk cycle \| Wireframe issue 14 Effective animation gave Donkey Kong barrels of personality. Raspberry Pi’s own Rik Cross* explains how to create a similar walk cycle.* Donkey Kong wasn’t the first game to feature an animated character who could walk and jump, but on its release in 1981, it certainly had more personality than the games that came before it. You only have to compare Donkey Kong to another Nintendo arcade game that came out just two years earlier — the half-forgotten top-down shooter Sheriff — to see how quickly both technology and pixel art moved on in that brief period. Although simple by modern standards, Donkey Kong’s hero Jumpman (later known as Mario) packed movement and personality into just a few frames of animation. In this article, I’ll show you how to use Python and Pygame to create a character with a simple walk cycle animation like Jumpman’s in Donkey Kong. The code can, however, be adapted for any game object that requires animation, and even for multiple game object animations, as I’ll explain later. Jumpman’s (aka Mario’s) walk cycle comprised just three frames of animation. Firstly, we’ll need some images to animate. As this article is focused on the animation code and not the theory behind creating walk cycle images, I grabbed some suitable images created by Kenney Vleugels and available at opengameart.org. Let’s start by animating the player with a simple walk cycle. The two images to be used in the animation are stored in an `images` list, and an `animationindex` variable keeps track of the index of the current image in the list to display. So, for a very simple animation with just two different frames, the `images` list will contain two different images: `images = [‘walkleft1’,‘walkleft2’` To achieve a looping animation, the `animationindex` is repeatedly incremented, and is reset to `0` once the end of the `images` list is reached. Displaying the current image can then be achieved by using the `animationindex` to reference and draw the appropriate image in the animation cycle: `self.image = self.images[self.state][self.animationindex]` A list of images along with an index is used to loop through an animation cycle. The problem with the code described so far is that the `animationindex` is incremented once per frame, and so the walk cycle will happen way too quickly, and won’t look natural. To solve this problem, we need to tell the player to update its animation every few frames, rather than every frame. To achieve this, we need another couple of variables; I’ll use `animationdelay` to store the number of frames to skip between displayed images, and `animationtimer` to store the number of frames since the last image change. Therefore, the code needed to animate the player becomes: `self.animationtimer += 1 if self.animationtimer >= self.animationdelay: self.animationtimer = 0 self.animationindex += 1 if self.animationindex > len(self.images) - 1: self.animationindex = 0 self.image = self.images[self.animationindex]` So we have a player that appears to be walking, but now the problem is that the player walks constantly, and always in the same direction! The rest of this article will show you how to solve these two related problems. There are a few different ways to approach this problem, but the method I’ll use is to make use of game object states, and then have different animations for each state. This method is a little more complicated, but it’s very adaptable. The first thing to do is to decide on what the player’s ‘states’ might be — `stand`, `walkleft`, and `walkright` will do as a start. Just as we did with our previous single animation, we can now define a list of images for each of the possible player’s states. Again, there are lots of ways of structuring this data, but I’ve opted for a Python dictionary linking states and image lists: `self.images = { ‘stand’ : [‘stand1’], ‘walkleft’ : [‘walkleft1’,‘walkleft2’], ‘walkright’ : [‘walkright1’,‘walkright2’] }` The player’s `state` can then be stored, and the correct image obtained by using the value of `state` along with the `animationindex:` `self.image = self.images[self.state][self.animationindex]` The correct player state can then be set by getting the keyboard input, setting the player to `walkleft` if the left arrow key is pressed or `walkright` if the right arrow key is pressed. If neither key is pressed, the player can be set to a `stand` state; the image list for which contains a single image of the player facing the camera. Animation cycles can be linked to player ‘states’. For simplicity, a maximum of two images are used for each animation cycle; adding more images would create a smoother or more realistic animation. Using the code above, it would also be possible to easily add additional states for, say, jumping or fighting enemies. You could even take things further by defining an `Animation()` object for each player state. This way, you could specify the speed and other properties (such as whether or not to loop) for each animation separately, giving you greater flexibility. Here’s Rik’s animated walk cycle, coded in Python. To get it running on your system, you’ll first need to install Pygame Zero. And to download the full code, go here.

2019/5/23 0:37	Raspberry Pi » Blog	His Royal Highness the Duke of York visits Raspberry Pi HQ We welcomed a very special guest to Raspberry Pi HQ today. Our Patron, His Royal Highness Prince Andrew, the Duke of York, visited our central Cambridge HQ to meet our team, learn more about our work, and give his support for our mission to help more young people learn how to create with computers. Royalty and Raspberry Pi Avid readers of this blog will know that this isn’t Raspberry Pi’s first royal encounter. Back in 2014, Raspberry Pi was one of the UK tech startups invited to showcase our product at a reception at Buckingham Palace. At that stage, we had just celebrated the sale of our two millionth credit card–sized computer. Fast forward to October 2016, when were celebrating the sale of our ten millionth Raspberry Pi computer with a reception at St James Palace and 150 members of our community. By this time, not only was our product flying off the shelves, but the Foundation had merged with Code Club, had expanded its teacher training programmes, and was working with thousands of volunteers to bring computing and digital making to tens of thousands of young people all over the world. Both of our trips to the royal palaces were hosted by Prince Andrew, who has long been a passionate advocate for technology businesses and digital skills. On top of his incredible advocacy work, he’s also an entrepreneur and innovator in his own right, founding and funding initiatives such as iDEA and Pitch at the Palace, which make a huge impact on digital skills and technology startups. We are really very fortunate to have him as our Patron. Leaps and bounds Today’s visit was an opportunity to update Prince Andrew on the incredible progress we’ve made towards our mission since that first trip to Buckingham Palace. We now have over 25 million Raspberry Pi computers in the wild, and people use them in education, in industry, and for their hobbies in an astonishing number of ways. Through our networks of Code Clubs and CoderDojos, we have supported more than a million young people to learn how to create with technology while also developing essential life skills such as teamwork, resilience, and creativity. You can read more about what we’ve achieved in our latest Annual Review. We talked with Prince Andrew about our work to support computing in the classroom, including the National Centre for Computing Education in England, and our free online teacher training that is being used by tens of thousands of educators all over the world to develop their skills and confidence. Prince Andrew shares our determination to encourage more girls to learn about computing and digital making, and we discussed our #realrolemodels campaign to get even more girls involved in Code Clubs and CoderDojos, as well as the groundbreaking gender research project that we’ve launched with support from the UK government. Dream team One of our rituals at the Raspberry Pi Foundation is the monthly all-staff meetup. On the third Wednesday of every month, colleagues from all over the world congregate in Cambridge to share news and updates, learn from each other, and plan together (and yes, we have a bit of fun too). My favourite part of Prince Andrew’s visit is that he organised it to coincide with the all-staff meetup. He spent most of his time speaking to team members and hearing about the work they do every day to bring our mission to life through creating educational resources, supporting our massive community of volunteers, training teachers, building partnerships, and much more. In his address to the team, he said: Raspberry Pi is one of those organisations that I have been absolutely enthralled by because of what you have enabled. The fact that there is this piece of hardware that started this, and that has led to educational work that reaches young people everywhere, is just wonderful. In the 21st century, every single person in the workplace is going to have to use and interact with some form of digital technology. The fact that you are giving the next generation the opportunity to get hands-on is fantastic. The post His Royal Highness the Duke of York visits Raspberry Pi HQ appeared first on Raspberry Pi.

2019/5/21 21:17	Raspberry Pi » Blog	The NSFW Roomba that screams when it bumps into stuff Hide yo’ kids, hide yo’ wife — today’s project is NSF(some)W, or for your kids. LOTS OF SWEARS. You have been warned. We’re not embedding the video here so you can decide for yourself whether or not to watch it — click on the image below to watch a sweary robot on YouTube. Michael Reeves is best known for such… educational Raspberry Pi projects as: The Subscriber Robot – a high-pitched buzzer that activates whenever someone subscribes to his YouTube channel The dab electrocution thing that electrocutes you, forcing you into a dab The robot that shines a laser in your eye – a robot that shines a laser in your eye He’s back, this time with yet another NSFW (depending on your W) project that triggers the sensors in a Roomba smart vacuum to scream in pain whenever it bumps into an object. Because why not? How it’s made We have no clue. So very done with fans asking for the project to be made — “I hate every single one of you!” — Michael refuses to say how he did it. But we know this much is true: the build uses optical sensors, relays, a radio receiver, and a Raspberry Pi. How do I know this? Because he showed us: But as for the rest? We leave it up to you, our plucky community of tinkerers, to figure it out. Share your guesses in the comments.

2019/5/20 20:56	Raspberry Pi » Blog	Build your own animatronic GLaDOS It’s 11 years since Steam’s Orange Box came out, which is probably making you feel really elderly. Portal was the highlight of the game bundle for me — cue giant argument in the comments — and it still holds up brilliantly. It’s even in the Museum of Modern Art’s collection; there’s nothing that quite says you’re part of the establishment like being in a museum. Cough. I bought an inflatable Portal turret to add to the decor in Raspberry Pi’s first office (I’m still not sure why; I just thought it was a good idea at the time, like the real-life Minecraft sword). Objects and sounds from the game have embedded themselves in pop culture; there’s a companion cube paperweight somewhere in my desk at home, and I bet you’ve encountered a cake that looks like this sometime in the last 11 years or so. But turrets, cakes, and companion cubes pale into viral insignificance next to the game’s outstanding antagonist, GLaDOS, a psychopathic AI system who just happens to be my favourite video game bad guy of all time. So I was extremely excited to see Element14’s DJ Harrigan make an animatronic GLaDOS, powered, of course, by a Raspberry Pi. Animitronic GLaDOS Head with Raspberry Pi The Portal franchise is one of the most engaging puzzle games of the last decade and beyond the mind-bending physics, is also known for its charming A.I. antagonist: G.L.a.D.O.S. Join DJ on his journey to build yet more robotic characters from pop culture as he “brings her to life” with a Raspberry Pi and sure dooms us all. Want to make your own? You’ll find everything you need here. I’ve been trying awfully hard not to end this post on a total cliche, but I’m failing hard: this was a triumph.
