Build your own South Park Buddha Box

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/south-park-raspberry-pi-buddha-box/

Escape the distractions of the world around you and focus your attention on the thing you love the most in life: your smartphone! It’s easy with the all-new Buddha Box, brought to you by South Park and the 8 Bits and a Byte team!

Introducing The All New Buddha Box | South Park

A brand new invention is sweeping South Park. The Buddha Box will let you escape from anything in the world so that you can focus on the thing you love the most… your phone.

The Buddha Box

Introduced in a recent episode of the cult show South Park, the Buddha Box is an ingenious invention that allows its user to ignore the outside world and fully immerse themselves in their smartphone. With noise-cancelling headphones and a screen so close to your eyes you’ll be seeing light spots for weeks to come, the Buddha Box is the must-have accessory for 2019.

We jest, obviously. It’s a horrible idea. And here’s how to make your own!

Build your own Buddha Box

Using a Raspberry Pi, noise-cancelling headphones, a screen, and a cardboard box, the wonderful 8 Bits and a Byte team has created a real-life Buddha Box that you definitely shouldn’t make yourself. As we said — horrible idea.

But it would be a great way to try out screensharing software on your Pi!

To make it, you’ll need to secure the headphones and a screen inside a suitably sized cardboard box, and then set up your Raspberry Pi to run Screencast.

The Screencast software allows you to cast the screen of your smartphone to the screen within the box — hence its name.

Here’s the tutorial from 8 Bits and a Byte, and a working demonstration:

Adding the Pi to Picasso with wireless digital graffiti

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/wiimote-graffiti-raspberry-pi/

It looks like the Nintendo Wii Remote (Wiimote) has become a staple in many maker toolkits! Case in point: with the help of a Raspberry Pi and the cwiid Python library, David Pride turned the popular piece of tech into a giant digital graffiti spraycan.

Raspberry Pi-powered Nintento Wiimote digital art

Using the Wiimote with a Raspberry Pi

While it’s no longer being updated and supported, the cwiid library is still a handy resource for creators who want to integrate the Wiimote with their Raspberry Pi.

Raspberry Pi-powered Nintento Wiimote digital art

Over the years, makers have used the Wiimote to control robots, musical instruments, and skateboards; the accessibility of the library plus the low cost and availability of the remote make using this tool a piece of cake…or pie, in this instance.

Digital graffiti

Using aWiimote, a Wii Sensor Bar, and a large display, David Pride hacked his way to digital artistry wonderment and enabled attendees of the Open University Knowledge Makers event to try their hand at wireless drawing. It’s kinda awesome.

OK, it’s all kinds of awesome. We really like it.

Digital graffiti ingredients

To construct David’s digital graffiti setup, you’ll need:

  • A Raspberry Pi
  • A Nintendo Wii Remote and a Wii Sensor Bar
  • A power supply and DC/DC power converter
  • A large display, e.g. a TV or projector screen
  • A 30mm × 30mm mirror and this 3D-printed holder

Putting it all together

David provides the step-by-step instructions for setting up the Wiimote and Raspberry Pi on his website, including a link to the GitHub repository with the complete project code. The gist of the build process is as follows:

Raspberry Pi-powered Nintento Wiimote digital art

After installing the cwiid library on the Raspberry Pi, David connected the Pi to the Wiimote via Bluetooth. And after some digging into the onboard libraries of the remote itself, he was able to access the infrared technology that lets the remote talk to the Sensor Bar.

Raspberry Pi-powered Nintento Wiimote digital art

The 3D-printed holder with which David augmented the Wiimote lets the user hold the remote upright like a spray can, while the integrated mirror reflects the IR rays so the Sensor Bar can detect them.

Raspberry Pi-powered Nintento Wiimote digital art

The Sensor Bar perceives the movement of the Wiimote, and this data is used to turn the user’s physical actions into works of art on screen. Neat!

If you’ve used the Nintendo Wiimote for your Raspberry Pi projects, let us know. And, speaking of the Wii, has anyone hacked their Balance Board with a Pi?

On a completely unrelated note…

How cool is this?!

Minecraft-controlled real world Christmas tree

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

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

Illuminating

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

Here’s a blurb from the BroCraft team:

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

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

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

Minecraft Pi

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

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

Google AIY Projects Kit vs Star Wars Porgs

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/star-wars-porg-google-aiy-translator/

Here at Pi Towers, we have a love/hate relationship with the Star Wars creatures known as Porgs. Love, because anything cute and annoying will instantly get our attention; hate, primarily because of this GIF:

Star Wars Porg Raspberry Pi Google AIY Projects Kit translator

So when hackster.io tweeted about the following project, you can imagine the unfiltered excitement and fear with which I shared the link in the comms team Slack channel.

It looked a little something like this:

Star Wars Porg Raspberry Pi Google AIY Projects Kit translator

Google AIY Projects Kit

When we announced the Google AIY Projects Kit as a freebie included in issue 57 of The MagPi, I don’t think we realised how well it would do. OK, no, we knew it would do well. After we gave away a free $5 computer on the front cover of issue 40, we knew giving tech away with The MagPi would always do well. But the wave of projects and applications that started on the day of the release was a wonderful surprise, as community members across the world immediately began to implement voice control in their builds.

Star Wars Porg Raspberry Pi Google AIY Projects Kit translator

And now, twenty months later, we’re still seeing some wonderful applications of the kit, including this glorious Porg project.

Learn Spanish with a Porg — because of course

Hackster.io user Paul Trebilcox-Ruiz shared his Translation Toy project on the site yesterday, providing a step-by-step guide to hacking the motors of the Star Wars Porg toy so that it moves in time with verbal responses from the AIY kit. It’s all rather nifty, and apart from a Raspberry Pi you only need some wires and a soldering iron to complete the project yourself.

…some wires, a soldering iron, and the cold-heartedness to pull apart the innards of a stuffed toy, Paul, you monster!

“Hello” Translation Toy

Uploaded by Paul Trebilcox-Ruiz on 2018-12-10.

As soon as Paul realised that the Porg’s motors would run if he simply applied voltage, he extended the wires inside the Porg with the help of jumper leads and so attached the Porg to the GPIO pins on his Raspberry Pi.

For this setup, I hooked the two speaker wires from the Porg into the speaker connectors on the HAT, the button wires into the GPIO pin 24 and ground connectors under the ‘Servos’ heading, and for the motors I needed to hook up a relay for a 5V connection driven by the signal off of GPIO pin 26. The microphone that came with the AIY Voice Projects Kit was attached to the board using the pre-defined mic connector.

Then Paul wrote code that uses the AIY kit to translate any voice command it hears into Spanish.

For the full code and instructions, check out Paul’s hackster.io project page. And for more Porg love, here’s every Porg scene from The Last Jedi:

Porgs! Love Them Or Hate Them – Every Porg Scene in Star Wars: The Last Jedi HD

Porgs are now part of the Star Wars universe for better or worse thanks to director Rian Johnson. How do you feel about the tasty critters? Thanks for watching

Bonus facts

  • Porgs were introduced into the Star Wars universe as a means of hiding the many puffins that traipse the landscape of Skellig Michael, the location used for filming Luke Skywalker’s home, Ahch-To. Bless you.
  • A group of Porgs is called a murder.
  • A baby Porg is called a Porglet.
  • And no, you can’t get a physical copy of The MagPi issue 40 or issue 57. They’re gone now. Done. Forever. But you can still download the PDFs.

We tried out Valve’s Steam Link on Raspberry Pi and…

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/steam-link-raspberry-pi/

… it worked well!

tl;dr: really, really well.

But if “it worked really well” isn’t enough of a reason for you to give Steam Link on Raspberry Pi a go, here’s the rest of today’s blog post…

Steam Link on Raspberry Pi

The internet (mainly Reddit) was all aflutter last week due to the release of the Steam Link app beta version for the Raspberry Pi.

Steam Link, for the uninitiated, is a service that allowed users of the digital distribution platform Steam to stream video games from their PC to a display of choice — without the need to weave a mile-long HDMI cable between rooms and furniture to connect computer and television.

The original Steam Link

Up until now, if Steam users wanted to stream games to other displays, they had to do so with Valve’s own Steam Link device — a small black box available for purchase on the Valve website — and the device did pretty well. But with the new Steam Link app for Raspberry Pi, any Pi owner can get up and running with Steam Link using one single line of code.

And that’s all sorts of convenient!

Trying out Steam Link for ourselves

We didn’t just want to put out a blog post to let you folks know that the app’s beta version is now live. Instead, we wanted to collar one of our own to try the new app out at home and let us know exactly what they think. And since we knew that Simon, our Asset Management Assistant Keeper of the Swag, Organiser of the Stuff, Lord Commander of the Things, had a Steam Link at home, it made sense to ask him nicely to give the app a try over the weekend.

And he did, because Simon = ❤

One line of code later…

It took Simon all of five minutes to get Steam Link up and running on his TV. He even went so far as to copy and paste the short line of code via a Chromium search for the announcement, instead of typing it in for himself.

And then Simon just had to sign into his Steam account and boom, Bob’s your uncle, Sally’s your aunt, the process was complete.

“Took less than five minutes before I was investigating strange cults from the comfort of my sofa,” explained Simon, as we all nodded, inwardly judging him a little for his game of choice. But in case you’re interested, Cultist Simulator is made by Factory Weather, and there are currently some photos of a tiny kitten on their homepage, so go check it out.

User experience

Let us know if you’ve tried the Steam Link app on Raspberry Pi, and what you think of it. Oh, and what games you’re playing on it, especially if they include Cultist Simulator.

And to make your Steam Link setup process easier, type rpf.io/steamlinkblog into your Chromium browser on your Raspberry Pi to open this blog post, and then copy and paste the following into a terminal window to run install the app:

curl -#Of http://media.steampowered.com/steamlink/rpi/steamlink_1.0.7_armhf.deb
sudo dpkg -i steamlink_1.0.7_armhf.deb

Reef-Pi: the ultimate Raspberry Pi fish tank management system

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/reef-pi-raspberry-pi-fish-tank-management-system/

If you’ve ever had a pet fish, even the saddest of fairground goldfish, you’ll appreciate how much work and attention they require. And to those who have never owned a fish: believe me, it’s more than you’d assume.

Reef-Pi

And the moment you upgrade from goldfish to brightly coloured, tropical beauties, and replace the standard silk reeds and gravel with live aquatic plants and soil, you suddenly have to factor in things like optimum temperature and chemical levels.

Reef-Pi

Reef-Pi

Thankfully, Adafruit Learning System author and loving fish parent Ranjib Dey has been working on a tutorial series called Reef-Pi, a collection of how-to guides that help you build the ultimate in Raspberry Pi reef aquarium management system.

Ranjib Dey on Twitter

@reef_pi at makerfaire #MFBA18

Reef-Pi monitors pH, chemical, and water levels, controls temperature, light, and power, and automates the management of these aspects so you don’t have to think about them. Phew!

And if you don’t fancy a massive coral-filled saltwater tank like Ranjib’s, you can use parts the Reef-Pi series for your own tank, whatever its setup, because many of the operations are similar or easy to adjust for your needs.

Jean Tannen

Any excuse to show off beautiful Jean to the world

Take, for example, my new Betta, Jean Tannen. While Jean’s tank is a much smaller size, and Jean its only resident (for now), I still need to keep an eye on the chemical balance of his water, the heat of his tank, and when his lights should be turned on or off. Even the most commonplace goldfish will appreciate many of the services Reef-Pi automates.

The Reef-Pi system uses a variety of components, including Raspberry Pi Zero and/or Raspberry Pi 3, and each stage of building the project is well-documented on the Adafruit Learning System. So if you’re looking to upgrade your tank, or have always fancied having pet fish but don’t want the hassle of tank management, give Reef-Pi a gander and see what you think.

We’re going to try it!

Sarah, our new Operations Manager, has been looking to upgrade her giant fish tank with a Raspberry Pi or two, so we’ll be sure to share her progress in the new year. If you decide to give Reef-Pi a try, or have already automated your tank with a Pi, let us know in the comments, or tag us on Twitter or Instagram!

Raspberry Pi vs a Raspberry Pi–powered escape room

Post Syndicated from Christina Foust original https://www.raspberrypi.org/blog/raspberry-pi-escape-room/

A few Mondays ago, the Raspberry Pi North America team visited a very special, Raspberry Pi–powered Escape Room in San Francisco. Run by Palace Games, the Edison Escape Room is an immersive experience full of lights, sensors, and plenty of surprises. This is the team’s story of how they entered, explored, and ultimately escaped this room.

At World Maker Faire this year, our very own social media star Alex Bate met Jordan Bunker, one of the Production Artists at Palace Games. Emails were sent, dates arranges, and boom, the Raspberry Pi North America team had to face the Edison Escape Room!

Escape rooms

In case you’re not familiar, an escape room is a physical adventure game in which players solve a series of puzzles and riddles using clues, logic, and strategy to complete the game’s objectives. Many escape room designers use physical computing to control the many sensors and triggers involved in the player experience.

Palace Games Edison Escape Room

The team vs Edison

Upon entering the Edison Escape Room, my team and I quickly realized that we were within a complex system built like a giant computer! So even though it was our first-ever time in an escape room, that would not be a disadvantage for us.

Palace Games Edison Escape Room

Our goal was to accomplish a variety of tasks, including solving many puzzles, looking for hidden clues when anything could be a clue, completing circuits, moving with the floor, and getting a bit of a workout.

The true test, however, was how well we communicated and worked with each other — which we did an awesome job at: at times we split up the work to effectively figure out the many different puzzles and clues; there was a lot “try it this way”, “maybe it means this”, and “what if it’s supposed to go that way” being yelled across the room. Everyone had their Edison thinking hat on that day, and we were so ecstatic when we completed the last challenge and finally escaped!

Palace Games Edison Escape Room

The inner workings

After escaping the room, we got the chance to explore behind the scenes. We found a local network of many Raspberry Pis that are coordinated by a central Raspberry Pi server. The Python Banyan framework is the connective tissue between the Raspberry Pis and their attached components.

Palace Games Edison Escape Room

The framework facilitates the communication between the Pis and the central server via Ethernet. The Raspberry Pis are used to read various types of sensors and to drive actuators that control lights, open doors, or play back media. And Raspberry Pis also drive the control panels that employees use to enter settings and keep tabs on the game.

“Raspberry Pi keeps us going. It’s the heart and soul of our rooms.”  – Elizabeth Sonder, Design Engineer & Production Manager

We highly recommend heading over to Palace Games and exploring one of their many escape rooms. It’s a great team-building exercise and definitely allows you to learn a lot about the people you work with. Thank you to the Palace Games team for hosting us, and we hope to return and escape one of their rooms again soon!

Three-factor authentication is the new two-factor authentication

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/three-factor-authentication-raspberry-pi/

Two-factor authentication continues to provide our online selves with more security for our email and online banking. Meanwhile, in the physical world, protecting our valuables is now all about three-factor authentication.

A GIF of a thumbprint being scanned for authentication - three-factor authentication

Not sure what I mean? Here’s a video from Switched On Network that demonstrates how to use a Raspberry Pi to build a three-factor door lock comprised of an RFID keyring, 6-digit passcode, and one-time access code sent to your mobile phone.

Note that this is a fairly long video, so feel free to skip it for now and read my rather snazzy tl;dr. You can come back to the video later, with a cup of tea and 20 minutes to spare. It’ll be worth it, I promise.

The tl;dr of three-factor door locks by Alex Bate

To build Switched On Network’s three-factor door lock, you need to source a Raspberry Pi 3, a USB RFID reader and fob, a touchscreen, a electronic door strike, and a relay switch. You also need a few other extras, such as a power supply and a glue gun.

A screenshot from the three-factor authentication video of a glue gun

Once you’ve installed the appropriate drivers (if necessary) for your screen, and rotated the display by 90 degrees, you can skip ahead a few steps by installing the Python script from Switched On Network’s GitHub repo! Cheers!

A screenshot from the three-factor authentication video of the screen attached to the Pi in portrait mode

Then for the physical build: you need to attach the door strike, leads, and whatnot to the Pi — and all that together to the door and door frame. Again, I won’t go into the details, since that’s where the video excels.

A screenshot from the video of the components of the three-factor authentication door lock

The end result is a superior door lock that requires you to remember both your keys and your phone in order to open it. And while we’d never suggest using this tech to secure your house from the outside, it’s a perfect setup for inside doors to offices or basement lairs.

Everyone should have a lair.

I feel the earth move under my feet (in Michigan)

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/michigan-seismic-activity-raspberry-pi/

The University of Michigan is home to the largest stadium in the USA (the second-largest in the world!). So what better place to test for spectator-induced seismic activity than The Big House?

The Big House stadium in Michigan

The Michigan Shake

University of Michigan geology professor Ben van der Pluijm decided to make waves by measuring the seismic activity produced during games at the university’s 107601 person-capacity stadium. Because earthquakes are (thankfully) very rare in the Midwest, and therefore very rarely experienced by van der Pluijm’s introductory geology class, he hoped this approach would make the movement of the Earth more accessible to his students.

“The bottom line was, I wanted something to show people that the Earth just shakes from all kinds of interactions,” explained van der Pluijm in his interview with The Michigan Daily. “All kinds of activity makes the Earth shake.”

The Big House stadium in Michigan

To measure the seismic activity, van der Pluijm used a Raspberry Pi, placing it on a flat concrete surface within the stadium.

Van der Pluijm installed a small machine called a Raspberry Pi computer in the stadium. He said his only requirements were that it needed to be able to plug into the internet and set up on a concrete floor. “Then it sits there and does its thing,” he said. “In fact, it probably does its thing right now.”

He then sent freshman student Sahil Tolia to some games to record the moments of spectator movement and celebration, so that these could be compared with the seismic activity that the Pi registers.

We’re not sure whether Professor van der Pluijm plans on releasing his findings to the outside world, or whether he’ll keep them a close secret with his introductory students, but we hope for the former!

Build your own Raspberry Pi seismic activity reader

We’re not sure what other technology van der Pluijm uses in conjunction with the Raspberry Pi, but it’s fairly easy to create your own seismic activity reader using our board. You can purchase the Raspberry Shake, an add-on board for the Pi that has vertical and horizontal geophones, MEMs accelerometers, and omnidirectional differential pressure transducers. Or you can fashion something at home, for example by taking hints from this project by Carlo Cristini, which uses household items to register movement.

Google Tasks to-do list, or anti-baby-distraction device

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/interactive-raspberry-pi-google-tasks/

Organise your life with the help of a Raspberry Pi, a 3.5″ touchscreen, Google Tasks, and hackster.io user Michal Sporna.

Distracting baby optional, though advised.

Google Tasks Raspberry Pi to-do list Michael Sporna

Baby – in the workplace – thought you ought to know

There’s a baby in the office today. And, as babies tend to do in places of work, he’s stolen all of our attention away from what we’re meant to be doing (our jobs), and has redirected it for the greater good (keeping him entertained). Oh, baby!

If only I had a to-do list to keep all my day’s tasks in plain sight and constantly remind myself of what I should be doing (writing this blog post) instead of what I’m actually doing (naming all the kittens on my T-shirt with the help of a nine-month-old)!

Hold on…

Sorry, the baby just came over to my desk and stole my attention again. Where was I?

Oh yes…

…to-do lists!

Michal Sporna‘s interactive to-do list that syncs with Google Tasks consists of a Raspberry Pi 3 Model B and a 3.5″ touchscreen encased in a laser-cut wooden housing, though this last element is optional.

Google Tasks Raspberry Pi to-do list Michael Sporna

“This is yet another web to-do app, but designed for a 3.5″ screen and Raspberry Pi,” says Michal in the introduction to his hackster.io tutorial. “The idea is for this device to serve as task tracking device, replacing a regular notebook and having to write stuff with pen.”

Michal explains that, while he enjoys writing down tasks on paper, editing items on paper isn’t that user-friendly. By replacing pen and paper with stylus and touchscreen, and making use Google Tasks, he improved the process for himself.

Google Tasks

The Google Tasks platform allows you to record and edit tasks, and to share them across multiple devices. The app integrates nicely with Gmail and Google Calendar, and its browser functionality allowed Michal to auto-run it on Chromium in Raspbian, so his tasks automatically display on the touchscreen. #NotSponsored

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/junie-genius/

It’s Monday. It’s morning. It’s England. The members of the Raspberry Pi Comms team begin to filter into Pi Towers, drowsy and semi-conscious. We’re tired from our weekends of debauchery.

One by one, we file into the kitchen. Fingers are clutching the handles of favourite mugs as we line up for the coffee machine. Select, click, wait. Select, click, wait. Double Americanos and Flat Whites pour, steaming hot and promising the glorious punch of caffeine to finally start our week.

Back in the office space, we turn on laptops, sign into Slack, and half-heartedly skim through pending messages while the coffee buzz begins to make its way through our systems, bringing us back to life.

“Ooooh”, comes a voice from the end desk, and heads turn towards Alex, who has opened the subscriptions page of the Raspberry Pi YouTube channel.

“Ooooh?” replies Helen, lifting herself from her chair to peer over the dividing wall between their desks.

“New Junie!”

Figures gather behind the Social Media Editor as she connects her laptop to her second display and enlarges the video to fullscreen.

It’s Monday. It’s morning. It’s England. And mornings like this are made for Junie Genius.

Your face, 14 ft tall: image mapping with As We Are

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/as-we-are-face-mapping/

While at World Maker Faire New York last weekend, I found myself chatting to a rather lovely gentleman by the name of Mac Pierce. During our conversation, Mac mentioned a project he’d worked on called As We Are, an interactive art installation located in the Greater Columbus Convention Center in Columbus, Ohio.

as we are

“So it’s this 14-foot head covered in LEDs…”, Mac began, and after his brief explanation, I found myself grabbing nearby makers to have him tell them about the project too. I was hooked! I hadn’t even seen photos of the sculpture, yet I was hooked. And true to his word, Mac had the press release for As We Are sitting in my inbox when I returned to Pi Towers.

So here is it:

The Greater Columbus Convention Center: “As We Are” – Creating the Ultimate Selfie Machine

DCL, an award-winning fabricator of architectural specialties and custom experiential design elements, worked with artist Matthew Mohr to develop, engineer and fabricate this 14ft, 7,000lb, interactive digital sculpture. Featuring custom LED modules, an integrated 3D photobooth, 32 cameras, and a touch-screen display – this unique project combines technologies to present a seamless experience for visitors to display their own portrait on the sculpture.

As We Are

The brainchild of artist Matthew Mohr, As We Are was engineered and produced by DCL, an award-winning Boston-based fabricator whose greatest achievement to date, in my opinion at least, is hiring Mac Pierce.

as we are

YAY!

DCL built the 14-foot structure using 24 layers of aluminium ‘ribs’ covered in custom Sansi LED modules. These modules add up to an astounding 850000 individual LEDs, allowing for crisp detail of images displayed by the build.

as we are

When a visitor to the Convention Center steps inside the interactive sculpture, they’re met with a wall of 32 Raspberry Pis plus Camera Modules. The Pis use facial recognition software to 3D scan the visitor’s face and flattened the image, and then map the face across the outer surface of the structure.

Matthew Mohr was inspired to show off the diversity of Columbus, OH, while also creating a sense of oneness with As We Are. Combining technology and interaction, the sculpture has been called “the ultimate selfie machine”.

If you’re in or near Columbus and able to visit the installation, we’d love to see your photos, so please share them with us on our social media platforms.

Raspberry Pi facial mapping as we are

You see now why I was dumbstruck when Mac told me about this project, yes?

Always tell us

Had it not been for a chance encounter with Mac at Maker Faire, we may never have heard of As We Are. While Matthew Mohr and DCL installed the sculpture in 2017, very little fuss was made about the use of Raspberry Pis within it, and it completely slipped under our radar. So if you are working on a project for your business, as a maker, or for any other reason, and you’re using a Raspberry Pi, please make sure to let us know by emailing [email protected].

Networked knitting machine: not your average knit one, purl one

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/knitting-network-printer/

The moment we saw Sarah Spencer‘s knitted Stargazing tapestry, we knew we needed to know more. A couple of emails later, and here’s Sarah with a guest blog post telling you all you need to know about her hacking adventure with a 1980s knitting machine and a Raspberry Pi.

Knitting Printer! (slowest speed)

Printing a scarf on a Brother KM950i knitting machine from the 1980’s. To do this I have a Brother Motor arm to push the carriage back and forth and a homemade colour changer that automatically selects the colour on the left (the white and purple device with the LED).

Here’s Sarah…

Raspberry Pi: what’s there not to like? It’s powerful, compact, and oh so affordable! I used one as a portable media box attached to a pico projector for years. Setting one up as a media box is one of the most popular uses for them, but there’s so much more you can do.

Cue a 1980s Brother domestic knitting machine. Yep, you read that right. A knitting machine – to knit jumpers, hats, scarves, you name it. They don’t make domestic knitting machines any more, so a machine from the 1980s is about as modern as you can get. It comes with an onboard scanner to scan knitting patterns and a floppy drive port to back up your scans to an old floppy disk. Aah, the eighties – what a time to be alive!

Building a networked knitting machine

But this is an article about Raspberry Pi, right? So what does a 30-year-old knitting machine have to do with that? Well, I hacked my domestic knitting machine and turned it into a network printer with the help of a Raspberry Pi. By using a floppy drive emulator written in Python and a web interface, I can send an image to the Raspberry Pi over the network, preview it in a knitting grid, and tell it to send the knitting pattern to the knitting machine via the floppy drive port.

OctoKnit

I call this set-up OctoKnit in honour of a more famous and widely used tool, OctoPrint for 3D printers, another popular application for Raspberry Pi.

Sarah Spencer Knitting Network Printer

I’ve made the OctoKnit web interface open source. You can find it on GitHub.

This project has been in the works for several years, and there’s been a few modifications to the knitting machine over that time. With the addition of a motor arm and an automatic colour changer, my knitting is getting very close to being hands-free. Here’s a photo of the knitting machine today, although the Raspberry Pi is hiding behind the machine in this shot:

Sarah Spencer Networked knitting machine

I’ve specialised in knitting multicolour work using a double-layered technique called double Jacquard, which requires two beds of needles. Hence the reason the machine has doubled in size from when I first started.

Knitting for Etsy

I made a thing that can make things, so I need to make something with it, right? Here are a few custom orders I’ve completed through my Etsy store:

Sarah Spencer Networked knitting machine

Stargazing

However, none of my previous works quite compares to my latest piece, Stargazing: a knitted tapestry. Knitted in seven panels stitched together by hand, the pattern on the Raspberry Pi is 21 times bigger than the memory available on the vintage knitting machine, so it’s knitted in 21 separate but seamless file transfers. It took over 100 hours of work and weighs 15kg.

Sarah Spencer Networked knitting machine

Stargazing is a celestial map of the night sky, featuring all 88 constellations across both Northern and Southern hemispheres. The line through the center is the Earth’s equator, projected out into space, with the sun, moon and planets of our solar system featured along it. The grey cloud is a representation of our galaxy, the Milky Way.

Heart of Pluto on Twitter

Happy 6pm, Fri 31st Aug 2018 😊 The tapestry is installed and the planets in the sky have now aligned with those in the knitting

When I first picked up a Raspberry Pi and turned it over in my hand, marvelling at the computing power in such a small, affordable unit, I never imagined in my wildest dreams what I’d end up doing with it.

What will you do with your Raspberry Pi?

How to mod your Etch A Sketch, or Toy Story in real life

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/mod-etch-a-sketch-toy-story/

We’d like to file this under ‘things we wish we’d had when we were younger’. Who else is envious of the kids of today and all the cool things they can make with our old classic toys?

Etch A Sketch Robot – Elephant

Read about how this works on my blog! http://sunnybala.com/2018/09/10/python-etch-a-sketch.html

To a wave of upvotes and comments, Sunny Balasubramanian shared their Etch A Sketch project on Reddit, including all the information and code you need to build your own. Thanks, Sunny!

Dismantling the toys of our childhoods

The physical set up of the automated Etch A Sketch is pretty simple: motors attached to couplers replace the original plastic nobs, and a connected Raspberry Pi 3 controls the motors as directed by the code.

Etch a Sketch modded with a Raspberry Pi

For stability, Sunny attached a wooden block to the plastic housing that keeps the motors in place.

Coding new life into an Etch A Sketch

Sunny explains:

There’s a few different ways to go about this portion of the project. When I started out, I googled to see if anyone had done things like this before. A few projects popped up. They seemed to approach the drawing in one of two ways. I wanted to do it in a fully automated way where the only input is a picture and the output is a cleanly drawn image.

The code Sunny ended up using first takes an image and simplifies it into a line drawing using Canny edge detection. It then turns each pixel to a node and draws a path between the nodes, connecting them one by one. So that the Etch A Sketch draws the picture, the Raspberry Pi then directs the motors to follow the connections and create uncannily precise sketches.

Head to Sunny’s website for more information about their project, and download the full code from GitHub.

Two down, more to go…

With this automated Etch A Sketch, and this talking Fisher Price Chatter Telephone, the Raspberry Pi community is well on the way to recreating the entire Toy Story cast, and we are fully on board with that!

So what’s next? A remote-controlled Slinky? A falling with style flying Buzz Lightyear? What would you build?

The Goodbye Machine. NSFW…ish? See what you think

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/raspberry-pi-goodbye-machine/

Tired of saying goodbye? Show people how you really feel with 8 Bits and a Byte‘s Goodbye Machine.

Spoiler alert: no one wants to be at the receiving end of the red button.

The Goodbye Machine: automate your goodbyes

The Goodbye Machine, a machine to automate goodbyes using a Raspberry Pi, two servo’s, two massive buttons and a speaker. Shoe box not included. All our projects in one place: http://8bitsandabyte.com/ Keep posted on Instagram: https://www.instagram.com/8bitsandabyte/ Follow us on Twitter! @NicoleHorward Music: Allen, L. & Kurstin, G. (2009). Fuck You.

Not all amazing projects require line upon line of code, hour upon hour of build time, or sheer masses of components. Sometimes even the simplest of buttons will do, as Carrie Anne explains in issue 1 of Hello World.

Goodbye to you

With their Goodbye Machine, Brussels-based YouTube makers 8 Bits and a Byte found a simple, entertaining solution to their “inability to say goodbye” using two servos, two buttons, a Raspberry Pi 3, and some lollipop sticks. Oh, and British musical royalty, James Blunt and Lily Allen.

Raspberry Pi Goodbye machine

When the positive green button is pressed, a hand appears, waving goodbye to the dulcet tones of James Blunt singing Goodbye My Lover. So darling.

However, press the negative red button and your departing acquaintance will be flipped the bird, as Lily Allen sings F*ck You.

Goodbye machine Raspberry Pi

It’s a very simple network of wires and code. Each button is given a task and when pressed, the task is completed. Anyone can learn this easy set of code, and create incredible projects as a result. And no, not all projects have to be so insulting… but we’re a little sadistic here at Pi Towers, and this sort of humour fits us perfectly.

For more information on building your own Goodbye Machine, visit the hackster.io project page.

Button it!

If you’d like to learn more about using buttons in digital making projects, these free resources from our projects site should get you started:

GPIO music box – wire up buttons to your Raspberry Pi’s GPIO pins and then use them to play sounds with a simple Python application.

Whoopi cushion – make a whoopee cushion powered by a Raspberry Pi.

Push button stop motion – make a stop-motion animation using a Raspberry Pi and a Camera Module to take pictures, controlled by a push-button.

Goodbye, so long, farewell

Since watching the video above for the first time, I’ve been unable to get Goodbye My Lover out of my head. If, like me, you’re suffering from a James Blunt earworm, here are some other goodbye-themed songs to listen to:

Beautiful and inspiring plinky-plonky conductivity

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/bare-conductive-installation-hwan-yun/

Recently shared by Bare Conductive, Hwan Yun‘s interactive installation, Intuition, uses a Raspberry Pi and Bare Conductive tech to transport you to the calm wonder of Icelandic nature.

Intuition (2017)

Rock, paper, scissors, lizard, Spock, fire, water balloon!

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/rock-paper-scissors-lizard-spock-fire-water-balloon/

Use a Raspberry Pi and a Pi Camera Module to build your own machine learning–powered rock paper scissors game!

Rock-Paper-Scissors game using computer vision and machine learning on Raspberry Pi

A Rock-Paper-Scissors game using computer vision and machine learning on the Raspberry Pi. Project GitHub page: https://github.com/DrGFreeman/rps-cv PROJECT ORIGIN: This project results from a challenge my son gave me when I was teaching him the basics of computer programming making a simple text based Rock-Paper-Scissors game in Python.

Virtual rock paper scissors

Here’s why you should always leave comments on our blog: this project from Julien de la Bruère-Terreault instantly had our attention when he shared it on our recent Android Things post.

Julien and his son were building a text-based version of rock paper scissors in Python when his son asked him: “Could you make a rock paper scissors game that uses the camera to detect hand gestures?” Obviously, Julien really had no choice but to accept the challenge.

“The game uses a Raspberry Pi computer and Raspberry Pi Camera Module installed on a 3D-printed support with LED strips to achieve consistent images,” Julien explains in the tutorial for the build. “The pictures taken by the camera are processed and fed to an image classifier that determines whether the gesture corresponds to ‘Rock’, ‘Paper’, or ‘Scissors’ gestures.”

How does it work?

Physically, the build uses a Pi 3 Model B and a Camera Module V2 alongside 3D-printed parts. The parts are all green, since a consistent colour allows easy subtraction of background from the captured images. You can download the files for the setup from Thingiverse.

rock paper scissors raspberry pi

To illustrate how the software works, Julien has created a rather delightful pipeline demonstrating where computer vision and machine learning come in.

rock paper scissors using raspberry pi

The way the software works means the game doesn’t need to be limited to the standard three hand signs. If you wanted to, you could add other signs such as ‘lizard’ and ‘Spock’! Or ‘fire’ and ‘water balloon’. Or any other alterations made to the game in your pop culture favourites.

Check out Julien’s full tutorial to build your own AI-powered rock paper scissors game here on Julien’s GitHub. Massive kudos to Julien for spending a year learning the skills required to make it happen. And a massive thank you to Julien’s son for inspiring him! This is why it’s great to do coding and digital making with kids — they have the best project ideas!

Some of the best bicycle projects for #CycleToWorkDay

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/bicycle-projects-cycletoworkday/

Avid followers of our Raspberry Pi Twitter account may be aware of just how bike-loving the residents of Pi Towers are. From the weekend cyclists to Cambridge-London-Cambridge racers, the flat land around our office calls us to jump on a bike and explore the fenlands.

#CycleToWorkDay

In celebration of #CycleToWorkDay, we’ve brought together a collection of some of our favourite bike-themed Raspberry Pi projects, perfect for those of you who enjoy a bike ride — or a pint!

Bicycle-powered beer dispenser

The Glaswegian company Bright Signals was tasked with a tasty project: create something for Menabrea that ties in with the Giro d’Italia cycle race passing close to the beer brewery in Biella, Northern Italy.

Menabrea Beer Bike Raspberry Pi #CycleToWorkDay

The result? This pedal- and Pi-powered beer dispenser that went on a 4-week celebratory tour ending in Glasgow.

You can learn more about this project here.

A rather dandy Pi-assisted Draisine

For a minute in the 1800s, before the introduction of pedal power, the balance bike, or Draisine, was the fun new way of getting from A to B.

Draisine 200.0

A team at Saarland University, Germany, headed by Prof. Holger Hermanns modernised the Draisine, bringing this old vehicle up to date with power assistance thanks to the Raspberry Pi.

Read more about this Draisine here.

Raspberry Pi–powered cycle helmet

Jen Fox’s Raspberry Pi safety helmet prototype uses an accelerometer and a Raspberry Pi Zero to monitor impact force, notifying the cyclist whether or not the impact of their fall deserves medical attention.

Make an Impact Force Monitor!

Check out my latest Hacker in Residence project for SparkFun Electronics: the Helmet Guardian! It’s a Pi Zero powered impact force monitor that turns on an LED if your head/body experiences a potentially dangerous impact. Install in your sports helmets, bicycle, or car to keep track of impact and inform you when it’s time to visit the doctor.

While you should always seek medical attention if you have a bike accident, the notification LED on the helmet is a great way of reminding stubborn cyclists that their accident was more than just a tumble.

Matt’s smart bike light

This one comes up in conversation A LOT at Pi Towers. Matt Richardson’s smart bike light project uses a Raspberry Pi and hall effect sensor to determine the speed you’re cycling at; a project displays your speed in front of the bike.

Raspberry Pi Dynamic Bike Headlight Prototype and Test

Here’s the first prototype of the Dynamic Bike Headlight. I managed to get it out onto the street to try it out, too!

The Bicrophonic Sonic Bike

British sound artist Kaffe Matthews has created a new type of cycling experience. The cyclist divides a virtual map into zones, and the Bicrophonic Sonic Bike plays back music to the rider based on which zone they are in, courtesy of an on-board Raspberry Pi with GPS dongle and speakers.

What is Bicrophonics?

Bicrophonics is about the mobility of sound, experienced and shared within a moving space, free of headphones and free of the internet. Music made by the journey you take, played with the space that you move through. The Bicrophonic Research Institute (BRI) http://sonicbikes.net

As you can see from the video, the sound played can range from the calming peace of the countryside to the rather loud, disturbing buzz of the city.

There’s Waldo! Finding the elusive traveller using AI

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/theres-waldo-wheres-wally/

Let me start by stating that here in the UK, we call Waldo Wally. And as I’m writing this post at my desk at Pi Towers, Cambridge, I have taken the decision to refer to the red and white-clad fellow as Wally moving forward.

Just so you know.

There’s Waldo is a robot that finds Waldo

There’s Waldo is a robot built to find Waldo and point at him. The robot arm is controlled by a Raspberry Pi using the PYARM Python library for the UARM Metal. Once initialized the arm is instructed to extend and take a photo of the canvas below.

The magical mind of Matt Reed

Both in his work and personal time, Matt Reed is a maker. In a nutshell, he has the job we all want — Creative Technologist — and gets to spend his working hours building interesting marketing projects for companies such as Redbull and Pi Towers favourite, Oreo. And lucky for us, he uses a Raspberry Pi in many of his projects — hurray!

Where’s Waldo Wally

With There’s Waldo, Matt has trained the AutoML Vision app, Google’s new image content analysis AI service, to recognise Wally in a series of images. With an AI model trained to recognise the features of the elusive traveller, a webcam attached to a Raspberry Pi 3B snaps a photo and the AI algorithm scans all faces, finding familiarities.

Matt Reed on Twitter

model is predicting WAAAYYY better than expected as this webcam image here wasn’t even part the training set. You can run from #ai but apparently can’t hide from #GoogleCloud

Once a match for Wally’s face is found with 95% or higher confidence, a robotic arm, controlled by the Pyarm Python library, points a comically small, plastic hand at where it believes Wally to be.

Deep learning and model training

We’ve started to discover more and more deep learning projects using Raspberry Pi — and with the recent release of TensorFlow 1.9 for the Pi, we’re sure this will soon become an even more common occurrence.
