Randomly generated, thermal-printed comics

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/random-comic-strip-generation-vomit-comic-robot/

Python code creates curious, wordless comic strips at random, spewing them from the thermal printer mouth of a laser-cut body reminiscent of Disney Pixar’s WALL-E: meet the Vomit Comic Robot!

The age of the thermal printer!

Thermal printers allow you to instantly print photos, data, and text using a few lines of code, with no need for ink. More and more makers are using this handy, low-maintenance bit of kit for truly creative projects, from Pierre Muth’s tiny PolaPi-Zero camera to the sound-printing Waves project by Eunice Lee, Matthew Zhang, and Bomani McClendon (and our own Secret Santa Babbage).

Vomiting robots

Interaction designer and developer Cadin Batrack, whose background is in game design and interactivity, has built the Vomit Comic Robot, which creates “one-of-a-kind comics on demand by processing hand-drawn images through a custom software algorithm.”

The robot is made up of a Raspberry Pi 3, a USB thermal printer, and a handful of LEDs.

Comic Vomit Robot Cadin Batrack's Raspberry Pi comic-generating thermal printer machine

At the press of a button, Processing code selects one of a set of Cadin’s hand-drawn empty comic grids and then randomly picks images from a library to fill in the gaps.

Each image is associated with data that allows the code to fit it correctly into the available panels. Cadin says about the concept behing his build:

Although images are selected and placed randomly, the comic panel format suggests relationships between elements. Our minds create a story where there is none in an attempt to explain visuals created by a non-intelligent machine.

The Raspberry Pi saves the final image as a high-resolution PNG file (so that Cadin can sell prints on thick paper via Etsy), and a Python script sends it to be vomited up by the thermal printer.

Raspberry Jam Cameroon #PiParty

Post Syndicated from Ben Nuttall original https://www.raspberrypi.org/blog/raspberry-jam-cameroon-piparty/

Earlier this year on 3 and 4 March, communities around the world held Raspberry Jam events to celebrate Raspberry Pi’s sixth birthday. We sent out special birthday kits to participating Jams — it was amazing to know the kits would end up in the hands of people in parts of the world very far from Raspberry Pi HQ in Cambridge, UK.

The Raspberry Jam Camer team: Damien Doumer, Eyong Etta, Loïc Dessap and Lionel Sichom, aka Lionel Tellem

Preparing for the #PiParty

One birthday kit went to Yaoundé, the capital of Cameroon. There, a team of four students in their twenties — Lionel Sichom (aka Lionel Tellem), Eyong Etta, Loïc Dessap, and Damien Doumer — were organising Yaoundé’s first Jam, called Raspberry Jam Camer, as part of the Raspberry Jam Big Birthday Weekend. The team knew one another through their shared interests and skills in electronics, robotics, and programming. Damien explains in his blog post about the Jam that they planned ahead for several activities for the Jam based on their own projects, so they could be confident of having a few things that would definitely be successful for attendees to do and see.

Show-and-tell at Raspberry Jam Cameroon

Loïc presented a Raspberry Pi–based, Android app–controlled robot arm that he had built, and Lionel coded a small video game using Scratch on Raspberry Pi while the audience watched. Damien demonstrated the possibilities of Windows 10 IoT Core on Raspberry Pi, showing how to install it, how to use it remotely, and what you can do with it, including building a simple application.

Loïc Dessap, wearing a Raspberry Jam Big Birthday Weekend T-shirt, sits at a table with a robot arm, a laptop with a Pi sticker and other components. He is making an adjustment to his set-up.

Loïc showcases the prototype robot arm he built

There was lots more too, with others discussing their own Pi projects and talking about the possibilities Raspberry Pi offers, including a Pi-controlled drone and car. Cake was a prevailing theme of the Raspberry Jam Big Birthday Weekend around the world, and Raspberry Jam Camer made sure they didn’t miss out.

Yay, birthday cake!!

A big success

Most visitors to the Jam were secondary school students, while others were university students and graduates. The majority were unfamiliar with Raspberry Pi, but all wanted to learn about Raspberry Pi and what they could do with it. Damien comments that the fact most people were new to Raspberry Pi made the event more interactive rather than creating any challenges, because the visitors were all interested in finding out about the little computer. The Jam was an all-round success, and the team was pleased with how it went:

What I liked the most was that we sensitized several people about the Raspberry Pi and what one can be capable of with such a small but powerful device. — Damien Doumer

The Jam team rounded off the event by announcing that this was the start of a Raspberry Pi community in Yaoundé. They hope that they and others will be able to organise more Jams and similar events in the area to spread the word about what people can do with Raspberry Pi, and to help them realise their ideas.

Raspberry Jam Camer gets the thumbs-up

The Raspberry Pi community in Cameroon

In a French-language interview about their Jam, the team behind Raspberry Jam Camer said they’d like programming to become the third official language of Cameroon, after French and English; their aim is to to popularise programming and digital making across Cameroonian society. Neither of these fields is very familiar to most people in Cameroon, but both are very well aligned with the country’s ambitions for development. The team is conscious of the difficulties around the emergence of information and communication technologies in the Cameroonian context; in response, they are seizing the opportunities Raspberry Pi offers to give children and young people access to modern and constantly evolving technology at low cost.

Thanks to Lionel, Eyong, Damien, and Loïc, and to everyone who helped put on a Jam for the Big Birthday Weekend! Remember, anyone can start a Jam at any time — and we provide plenty of resources to get you started. Check out the Guidebook, the Jam branding pack, our specially-made Jam activities online (in multiple languages), printable worksheets, and more.

UK soldiers design Raspberry Pi bomb disposal robot

Post Syndicated from Helen Lynn original https://www.raspberrypi.org/blog/uk-soldiers-design-raspberry-pi-bomb-disposal-robot/

Three soldiers in the British Army have used a Raspberry Pi to build an autonomous robot, as part of their Foreman of Signals course.

Meet The Soldiers Revolutionising Bomb Disposal

Three soldiers from Blandford Camp have successfully designed and built an autonomous robot as part of their Foreman of Signals Course at the Dorset Garrison.

Autonomous robots

Forces Radio BFBS carried a story last week about Staff Sergeant Jolley, Sergeant Rana, and Sergeant Paddon, also known as the “Project ROVER” team. As part of their Foreman of Signals training, their task was to design an autonomous robot that can move between two specified points, take a temperature reading, and transmit the information to a remote computer. The team comments that, while semi-autonomous robots have been used as far back as 9/11 for tasks like finding people trapped under rubble, nothing like their robot and on a similar scale currently exists within the British Army.

The ROVER buggy

Their build is named ROVER, which stands for Remote Obstacle aVoiding Environment Robot. It’s a buggy that moves on caterpillar tracks, and it’s tethered; we wonder whether that might be because it doesn’t currently have an on-board power supply. A demo shows the robot moving forward, then changing its path when it encounters an obstacle. The team is using RealVNC‘s remote access software to allow ROVER to send data back to another computer.

Applications for ROVER

Dave Ball, Senior Lecturer in charge of the Foreman of Signals course, comments that the project is “a fantastic opportunity for [the team] to, even only halfway through the course, showcase some of the stuff they’ve learnt and produce something that’s really quite exciting.” The Project ROVER team explains that the possibilities for autonomous robots like this one are extensive: they include mine clearance, bomb disposal, and search-and-rescue campaigns. They point out that existing semi-autonomous hardware is not as easy to program as their build. In contrast, they say, “with the invention of the Raspberry Pi, this has allowed three very inexperienced individuals to program a robot very capable of doing these things.”

We make Raspberry Pi computers because we want building things with technology to be as accessible as possible. So it’s great to see a project like this, made by people who aren’t techy and don’t have a lot of computing experience, but who want to solve a problem and see that the Pi is an affordable and powerful tool that can help.

Puerto Rico’s First Raspberry Pi Educator Workshop

Post Syndicated from Dana Augustin original https://www.raspberrypi.org/blog/puerto-rico-raspberry-pi-workshop/

Earlier this spring, an excited group of STEM educators came together to participate in the first ever Raspberry Pi and Arduino workshop in Puerto Rico.

Their three-day digital making adventure was led by MakerTechPR’s José Rullán and Raspberry Pi Certified Educator Alex Martínez. They ran the event as part of the Robot Makers challenge organized by Yees! and sponsored by Puerto Rico’s Department of Economic Development and Trade to promote entrepreneurial skills within Puerto Rico’s education system.

Over 30 educators attended the workshop, which covered the use of the Raspberry Pi 3 as a computer and digital making resource. The educators received a kit consisting of a Raspberry Pi 3 with an Explorer HAT Pro and an Arduino Uno. At the end of the workshop, the educators were able to keep the kit as a demonstration unit for their classrooms. They were enthusiastic to learn new concepts and immerse themselves in the world of physical computing.

In their first session, the educators were introduced to the Raspberry Pi as an affordable technology for robotic clubs. In their second session, they explored physical computing and the coding languages needed to control the Explorer HAT Pro. They started off coding with Scratch, with which some educators had experience, and ended with controlling the GPIO pins with Python. In the final session, they learned how to develop applications using the powerful combination of Arduino and Raspberry Pi for robotics projects. This gave them a better understanding of how they could engage their students in physical computing.

“The Raspberry Pi ecosystem is the perfect solution in the classroom because to us it is very resourceful and accessible.” – Alex Martínez

Computer science and robotics courses are important for many schools and teachers in Puerto Rico. The simple idea of programming a microcontroller from a $35 computer increases the chances of more students having access to more technology to create things.

Puerto Rico’s education system has faced enormous challenges after Hurricane Maria, including economic collapse and the government’s closure of many schools due to the exodus of families from the island. By attending training like this workshop, educators in Puerto Rico are becoming more experienced in fields like robotics in particular, which are key for 21st-century skills and learning. This, in turn, can lead to more educational opportunities, and hopefully the reopening of more schools on the island.

“We find it imperative that our children be taught STEM disciplines and skills. Our goal is to continue this work of spreading digital making and computer science using the Raspberry Pi around Puerto Rico. We want our children to have the best education possible.” – Alex Martínez

After attending Picademy in 2016, Alex has integrated the Raspberry Pi Foundation’s online resources into his classroom. He has also taught small workshops around the island and in the local Puerto Rican makerspace community. José is an electrical engineer, entrepreneur, educator and hobbyist who enjoys learning to use technology and sharing his knowledge through projects and challenges.

RDS for Oracle: Extending Outbound Network Access to use SSL/TLS

Post Syndicated from Surya Nallu original https://aws.amazon.com/blogs/architecture/rds-for-oracle-extending-outbound-network-access-to-use-ssltls/

In December 2016, we launched the Outbound Network Access functionality for Amazon RDS for Oracle, enabling customers to use their RDS for Oracle database instances to communicate with external web endpoints using the utl_http and utl tcp packages, and sending emails through utl_smtp. We extended the functionality by adding the option of using custom DNS servers, allowing such outbound network accesses to make use of any DNS server a customer chooses to use. These releases enabled HTTP, TCP and SMTP communication originating out of RDS for Oracle instances – limited to non-secure (non-SSL) mediums.

To overcome the limitation over SSL connections, we recently published a whitepaper, that guides through the process of creating customized Oracle wallet bundles on your RDS for Oracle instances. By making use of such wallets, you can now extend the Outbound Network Access capability to have external communications happen over secure (SSL/TLS) connections. This opens up new use cases for your RDS for Oracle instances.

With the right set of certificates imported into your RDS for Oracle instances (through Oracle wallets), your database instances can now:

  • Communicate with a HTTPS endpoint: Using utl_http, access a resource such as https://status.aws.amazon.com/robots.txt
  • Download files from Amazon S3 securely: Using a presigned URL from Amazon S3, you can now download any file over SSL
  • Extending Oracle Database links to use SSL: Database links between RDS for Oracle instances can now use SSL as long as the instances have the SSL option installed
  • Sending email over SMTPS:
    • You can now integrate with Amazon SES to send emails from your database instances and any other generic SMTPS with which the provider can be integrated

These are just a few high-level examples of new use cases that have opened up with the whitepaper. As a reminder, always ensure to have best security practices in place when making use of Outbound Network Access (detailed in the whitepaper).

Hackspace magazine 6: Paper Engineering

Post Syndicated from Andrew Gregory original https://www.raspberrypi.org/blog/hackspace-magazine-6/

HackSpace magazine is back with our brand-new issue 6, available for you on shop shelves, in your inbox, and on our website right now.

Inside Hackspace magazine 6

Paper is probably the first thing you ever used for making, and for good reason: in no other medium can you iterate through 20 designs at the cost of only a few pennies. We’ve roped in Rob Ives to show us how to make a barking paper dog with moveable parts and a cam mechanism. Even better, the magazine includes this free paper automaton for you to make yourself. That’s right: free!

At the other end of the scale, there’s the forge, where heat, light, and noise combine to create immutable steel. We speak to Alec Steele, YouTuber, blacksmith, and philosopher, about his amazingly beautiful Damascus steel creations, and about why there’s no difference between grinding a knife and blowing holes in a mountain to build a road through it.

HackSpace magazine 6 Alec Steele

Do it yourself

You’ve heard of reading glasses — how about glasses that read for you? Using a camera, optical character recognition software, and a text-to-speech engine (and of course a Raspberry Pi to hold it all together), reader Andrew Lewis has hacked together his own system to help deal with age-related macular degeneration.

It’s the definition of hacking: here’s a problem, there’s no solution in the shops, so you go and build it yourself!

Radio

60 years ago, the cutting edge of home hacking was the transistor radio. Before the internet was dreamt of, the transistor radio made the world smaller and brought people together. Nowadays, the components you need to build a radio are cheap and easily available, so if you’re in any way electronically inclined, building a radio is an ideal excuse to dust off your soldering iron.

Tutorials

If you’re a 12-month subscriber (if you’re not, you really should be), you’ve no doubt been thinking of all sorts of things to do with the Adafruit Circuit Playground Express we gave you for free. How about a sewable circuit for a canvas bag? Use the accelerometer to detect patterns of movement — walking, for example — and flash a series of lights in response. It’s clever, fun, and an easy way to add some programmable fun to your shopping trips.


We’re also making gin, hacking a children’s toy car to unlock more features, and getting started with robot sumo to fill the void left by the cancellation of Robot Wars.

Colour sensing with a Raspberry Pi

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

In their latest video and tutorial, Electronic Hub shows you how to detect colour using a Raspberry Pi and a TCS3200 colour sensor.

Raspberry Pi Color Sensor (TCS3200) Interface | Color Detector

A simple Raspberry Pi based project using TCS3200 Color Sensor. The project demonstrates how to interface a Color Sensor (like TCS3200) with Raspberry Pi and implement a simple Color Detector using Raspberry Pi.

What is a TCS3200 colour sensor?

Colour sensors sense reflected light from nearby objects. The bright light of the TCS3200’s on-board white LEDs hits an object’s surface and is reflected back. The sensor has an 8×8 array of photodiodes, which are covered by either a red, blue, green, or clear filter. The type of filter determines what colour a diode can detect. Then the overall colour of an object is determined by how much light of each colour it reflects. (For example, a red object reflects mostly red light.)

Colour sensing with the TCS3200 Color Sensor and a Raspberry Pi

As Electronics Hub explains:

TCS3200 is one of the easily available colour sensors that students and hobbyists can work on. It is basically a light-to-frequency converter, i.e. based on colour and intensity of the light falling on it, the frequency of its output signal varies.

I’ll save you a physics lesson here, but you can find a detailed explanation of colour sensing and the TCS3200 on the Electronics Hub blog.

Raspberry Pi colour sensor

The TCS3200 colour sensor is connected to several of the onboard General Purpose Input Output (GPIO) pins on the Raspberry Pi.

Colour sensing with the TCS3200 Color Sensor and a Raspberry Pi

These connections allow the Raspberry Pi 3 to run one of two Python scripts that Electronics Hub has written for the project. The first displays the RAW RGB values read by the sensor. The second detects the primary colours red, green, and blue, and it can be expanded for more colours with the help of the first script.

Colour sensing with the TCS3200 Color Sensor and a Raspberry Pi

Electronic Hub’s complete build uses a breadboard for simply prototyping

Use it in your projects

This colour sensing setup is a simple means of adding a new dimension to your builds. Why not build a candy-sorting robot that organises your favourite sweets by colour? Or add colour sensing to your line-following buggy to allow for multiple path options!

If your Raspberry Pi project uses colour sensing, we’d love to see it, so be sure to share it in the comments!

AIY Projects 2: Google’s AIY Projects Kits get an upgrade

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/google-aiy-projects-2/

After the outstanding success of their AIY Projects Voice and Vision Kits, Google has announced the release of upgraded kits, complete with Raspberry Pi Zero WH, Camera Module, and preloaded SD card.

Google AIY Projects Vision Kit 2 Raspberry Pi

Google’s AIY Projects Kits

Google launched the AIY Projects Voice Kit last year, first as a cover gift with The MagPi magazine and later as a standalone product.

Makers needed to provide their own Raspberry Pi for the original kit. The new kits include everything you need, from Pi to SD card.

Within a DIY cardboard box, makers were able to assemble their own voice-activated AI assistant akin to the Amazon Alexa, Apple’s Siri, and Google’s own Google Home Assistant. The Voice Kit was an instant hit that spurred no end of maker videos and tutorials, including our own free tutorial for controlling a robot using voice commands.

Later in the year, the team followed up the success of the Voice Kit with the AIY Projects Vision Kit — the same cardboard box hosting a camera perfect for some pretty nifty image recognition projects.

For more on the AIY Voice Kit, here’s our release video hosted by the rather delightful Rob Zwetsloot.

AIY Projects adds natural human interaction to your Raspberry Pi

Check out the exclusive Google AIY Projects Kit that comes free with The MagPi 57! Grab yourself a copy in stores or online now: http://magpi.cc/2pI6IiQ This first AIY Projects kit taps into the Google Assistant SDK and Cloud Speech API using the AIY Projects Voice HAT (Hardware Accessory on Top) board, stereo microphone, and speaker (included free with the magazine).

AIY Projects 2

So what’s new with version 2 of the AIY Projects Voice Kit? The kit now includes the recently released Raspberry Pi Zero WH, our Zero W with added pre-soldered header pins for instant digital making accessibility. Purchasers of the kits will also get a micro SD card with preloaded OS to help them get started without having to set the card up themselves.

Google is also hard at work producing AIY Projects companion apps for Android, iOS, and Chrome. The Android app is available now to coincide with the launch of the upgraded kits, with the other two due for release soon. The app supports wireless setup of the AIY Kit, though avid coders will still be able to hack theirs to better suit their projects.

Google has also updated the AIY Projects website with an AIY Models section highlighting a range of neural network projects for the kits.

Get your kit

The updated Voice and Vision Kits were announced last night, and in the US they are available now from Target. UK-based makers should be able to get their hands on them this summer — keep an eye on our social channels for updates and links.

Take home Mugsy, the Raspberry Pi coffee robot

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/mugsy/

We love Mugsy, the Raspberry Pi coffee robot that has smashed its crowdfunding goal within days! Our latest YouTube video shows our catch-up with Mugsy and its creator Matthew Oswald at Maker Faire New York last year.

MUGSY THE RASPBERRY PI COFFEE ROBOT #MFNYC

Uploaded by Raspberry Pi on 2018-03-22.

Mugsy

Labelled ‘the world’s first hackable, customisable, dead simple, robotic coffee maker’, Mugsy allows you to take control of every aspect of the coffee-making process: from grind size and water temperature, to brew and bloom time. Feeling lazy instead? Read in your beans’ barcode via an onboard scanner, and it will automatically use the best settings for your brew.

Mugsy Raspberry Pi Coffee Robot

Looking to start your day with your favourite coffee straight out of bed? Send the robot a text, email, or tweet, and it will notify you when your coffee is ready!

Learning through product development

“Initially, I used [Mugsy] as a way to teach myself hardware design,” explained Matthew at his Editor’s Choice–winning Maker Faire stand. “I really wanted to hold something tangible in my hands. By using the Raspberry Pi and just being curious, anytime I wanted to use a new technology, I would try to pull back [and ask] ‘How can I integrate this into Mugsy?’”

Mugsy Raspberry Pi Coffee Robot

By exploring his passions and using Mugsy as his guinea pig, Matthew created a project that not only solves a problem — how to make amazing coffee at home — but also brings him one step closer to ‘making things’ for a living. “I used to dream about this stuff when I was a kid, and I used to say ‘I’m never going to be able to do something like that.’” he admitted. But now, with open-source devices like the Raspberry Pi so readily available, he “can see the end of the road”: making his passion his livelihood.

SoFi, the underwater robotic fish

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/robotic-fish/

With the Greenland shark finally caught on video for the very first time, scientists and engineers are discussing the limitations of current marine monitoring technology. One significant advance comes from the CSAIL team at Massachusetts Institute of Technology (MIT): SoFi, the robotic fish.

A Robotic Fish Swims in the Ocean

The untethered SoFi robot

Last week, the Computer Science and Artificial Intelligence Laboratory (CSAIL) team at MIT unveiled SoFi, “a soft robotic fish that can independently swim alongside real fish in the ocean.”

Directed by a Super Nintendo controller and acoustic signals, SoFi can dive untethered to a maximum of 18 feet for a total of 40 minutes. A Raspberry Pi receives input from the controller and amplifies the ultrasound signals for SoFi via a HiFiBerry. The controller, Raspberry Pi, and HiFiBerry are sealed within a waterproof, cast-moulded silicone membrane filled with non-conductive mineral oil, allowing for underwater equalisation.

The ultrasound signals, received by a modem within SoFi’s head, control everything from direction, tail oscillation, pitch, and depth to the onboard camera.

As explained on MIT’s news blog, “to make the robot swim, the motor pumps water into two balloon-like chambers in the fish’s tail that operate like a set of pistons in an engine. As one chamber expands, it bends and flexes to one side; when the actuators push water to the other channel, that one bends and flexes in the other direction.”

Ocean exploration

While we’ve seen many autonomous underwater vehicles (AUVs) using onboard Raspberry Pis, SoFi’s ability to roam untethered with a wireless waterproof controller is an exciting achievement.

“To our knowledge, this is the first robotic fish that can swim untethered in three dimensions for extended periods of time. We are excited about the possibility of being able to use a system like this to get closer to marine life than humans can get on their own.” – CSAIL PhD candidate Robert Katzschmann

As the MIT news post notes, SoFi’s simple, lightweight setup of a single camera, a motor, and a smartphone lithium polymer battery set it apart it from existing bulky AUVs that require large motors or support from boats.

The robotic teapot from your nightmares

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/robotic-teapot/

For those moments when you wish the cast of Disney’s Beauty and the Beast was real, only to realise what a nightmare that would be, here’s Paul-Louis Ageneau’s robotic teapot!

Paul-Louis Ageneau Robotic teapot Raspberry Pi Zero

See what I mean?

Tale as old as time…

It’s the classic story of guy meets digital killer teapot, digital killer teapot inspires him to 3D print his own. Loosely based on a boss level of the video game Alice: Madness Returns, Paul-Louis’s creation is a one-eyed walking teapot robot with a (possible) thirst for blood.

Kill Build the beast

“My new robot is based on a Raspberry Pi Zero W with a camera.” Paul-Louis explains in his blog. “It is connected via a serial link to an Arduino Pro Mini board, which drives servos.”

Each leg has two points of articulation, one for the knee and one for the ankle. In order to move each of the joints, the teapot uses eight servo motor in total.

Paul-Louis designed and 3D printed the body of the teapot to fit the components needed. So if you’re considering this build as a means of acquiring tea on your laziest of days, I hate to be the bearer of bad news, but the most you’ll get from your pour will be jumper leads and Pi.

While the Arduino board controls the legs, it’s the Raspberry Pi’s job to receive user commands and tell the board how to direct the servos. The protocol for moving the servos is simple, with short lines of characters specifying instructions. First a digit from 0 to 7 selects a servo; next the angle of movement, such as 45 or 90, is input; and finally, the use of C commits the instruction.

Typing in commands is great for debugging, but you don’t want to be glued to a keyboard. Therefore, Paul-Louis continued to work on the code in order to string together several lines to create larger movements.

The final control system of the teapot runs on a web browser as a standard four-axis arrow pad, with two extra arrows for turning.

Something there that wasn’t there before

Jean-Paul also included an ‘eye’ in the side of the pot to fit the Raspberry Pi Camera Module as another nod to the walking teapot from the video game, but with a purpose other than evil and wrong-doing. As you can see from the image above, the camera live-streams footage, allowing for remote control of the monster teapot regardless of your location.

If you like it all that much, it’s yours

In case you fancy yourself as an inventor, Paul-Louis has provided the entire build process and the code on his blog, documenting how to bring your own teapot to life. And if you’ve created any robotic household items or any props from video games or movies, we’d love to see them, so leave a link in the comments or share it with us across social media using the hashtag #IBuiltThisAndNowIThinkItIsTryingToKillMe.

AWS Quest- a puzzling situation

Post Syndicated from Ana Visneski original https://aws.amazon.com/blogs/aws/aws-quest-a-puzzling-situation/

Ain't nobody here but us chickens. No clues hidden here this time!Starting on March 8th you might have seen AWS Quest popping up in different places. Now that we are a bit over halfway through the game, we thought it would be a great time give everyone a peek behind the curtain.

The whole idea started about a year ago during an casual conversation with Jeff when I first joined AWS. While we’re usually pretty good at staying focused in our meetings, he brought up that he had just finished a book he really enjoyed and asked me if I had read it. (A book that has since been made into a movie.) I don’t think there was a way for him to even imagine that as a huge fan of games, both table top and video games, how stoked I would be about the idea of bringing a game to our readers.

We got to talking about how great it would be to attempt a game that would involve the entire suite of AWS products and our various platforms. This idea might appear to be easy, but it has kept us busy with Lone Shark for about a year and we haven’t even scratched the surface of what we would like to do. Being able to finally share this first game with our customers has been an absolute delight.

From March 8-27th, each day we have been and will be releasing a new puzzle. The clues for the puzzles are hidden somewhere all over AWS, and once customers have found the clues they can figure out the puzzle which results in a word. That word is the name of a component to rebuild Ozz, Jeff’s robot buddy.

We wanted to try make sure that anyone could play and we tried to surround each puzzle with interesting Easter eggs. So far, it seems to be working and we are seeing some really cool collaborative effort between customers to solve the puzzles. From tech talks to women who code, posts both recent and well in the past, and to Twitter and podcasts, we wanted to hide the puzzles in places our customers might not have had a chance to really explore before. Given how much Jeff enjoyed doing a live Twitch stream so much I won’t be surprised when he tells me he wants to do a TV show next.

So far players have solved 8 of 13 puzzles!

09 Mar 10 Mar 11 Mar 12 Mar 13 Mar 14 Mar 15 Mar 16 Mar 17 Mar 18 Mar 19 Mar 20 Mar

The learnings we have already gathered as we are just a little past halfway in the quest are mind boggling. We have learned that there will be a guy who figures out how to build a chicken coop in 3D to solve a puzzle, or build a script to crawl a site looking for any reply to a blog post that might be a clue. There were puzzles we completely expected people to get stuck on that they have solved in a snap. They have really kept us on our toes, which isn’t a bad thing. It really doesn’t hurt that the players are incredibly adept at thinking outside the box, and we can’t wait to tell you how the puzzles were solved at the end.

We still have a little under a week of puzzles to go, before you can all join Jeff and special guests on a live Twitch stream to reassemble Ozz 2.0! And you don’t have to hold off for the next time we play, as there are still many puzzles to be solved and every player matters! Just keep an eye out for new puzzles to appear everyday until March 27th, join the Reddit, come to the AMA, or take a peek into the chat and get solving!

Time to wipe off your brow, and get back into solving the last of the puzzles! I am going to try to go explain to my mother and father what exactly I am doing with those two masters degrees and how much fun it really is…
