Eight(ish) Raspberry Pi projects for the summer

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

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

Air quality monitors and solar radiation

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

Raspberry Pi summer project

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

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

Particulater air quality Oliver Crask Raspberry Pi summer project

Maker Oliver Crask describes the project:

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

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

Automatic pet and plant feeders

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

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

Raspberry Pi summer project

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

Planty Project

Electromagnetic bike shed lock

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

Raspberry Pi summer project

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

Time-lapse cameras

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

Slider Test Sunset

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

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

Infrared laser tag

Raspberry Pi summer project

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

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

Self-weighing smart suitcase

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

Raspberry Pi summer project

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

Our free resources

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

Dialling into local stories with Jura whisky phones

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/local-stories-jura-whisky-phones/

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

Raspberry Pi Bright Signal Jura whisky

Jura whisky from Jura

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

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

Building phones for Jura

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

Retrofitting phoneboxes

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

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

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

Raspberry Pi Bright Signal Jura whisky

Motion sensor–triggered phone calls

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

Raspberry Pi Bright Signal Jura whisky

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

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

Your own Grand Theft Auto San Andreas radio

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/grand-theft-auto-radio/

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

Raphaël Yancey on Twitter

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

…and now I have Barracuda stuck in my head.

The music of GTA

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

GTA

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

Hacking a radio

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

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

GTA Radio

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

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

Raspberry Pi and music

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

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

Tired of queuing for the office toilet? Meet Occu-Pi

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/office-toilet-occu-pi/

This is the story of Occu-Pi, or how a magnet, a Raspberry Pi, and a barrel bolt saved an office team from queuing for the toilet.

Occu Pi Raspberry Pi toilet signal

The toil of toilet queuing

When Brian W. Wolter’s employer moved premises, the staff’s main concern as the dearth of toilets at the new office, and the increased queuing time this would lead to:

Our previous office had long been plagued by unreasonably long bathroom lines. At several high-demand periods throughout the day we’d be forced to wait three, four, five people deep while complaining bitterly to each other until our turn to use the facilities arrived. With even fewer bathrooms in our new office, concern about timely access was naturally high.

Faced with this problem, the in-house engineers decided to find a technological solution.

Occu-Pi

The main thing the engineers had to figure out was just how to determine the difference between a closed door and an occupied stall. Brian explains in his write-up:

There is one notable wrinkle: it’s not enough to know the door is closed, you need to know if the bathroom is actually in use — that is, locked from the inside. After considering and discarding a variety of ‘creative’ solutions (no thank you, motion sensors and facial recognition), we landed on a straightforward and reliable approach.

The team ended up using a magnet attached to the door’s barrel bolt to trigger a notification. Simply shutting the door doesn’t act as a trigger — the bolt needs to lock the door to set off a magnetic switch. That switch then triggers both LED notifications and updates to a dedicated Slack channel.

Occu-Pi Raspberry Pi toilet signal

For the technically-minded, Occu-Pi is a pretty straightforward build. And those wanting to learn more about it can find a full write-up in Brian’s Medium post.

We’ve seen a few different toilet notification projects over the years, for example this project from DIY Tryin’ using a similar trigger plus a website. What’s nice about Occu-Pi, however, is the simplicity of its design and the subtle use of Slack — Pi Tower’s favoured platform for office shenanigans.

Track your speed and distance while skateboarding

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/speed-distance-tracking-skateboard/

Fight the urge to chant the Avril Lavigne song as you cruise the streets on Pieter Thomas’s speed- and distance-tracking skateboard.

Speed and distance tracking Raspberry Pi skateboard

Instant approval

“That is sweet!” exclaimed Ben Nuttall when I shared this project on the Raspberry Pi Slack channel. And indeed it is — a simple idea, perfectly executed, resulting in a final product that actually managed to coax a genuine and positive response from Ben!

Prove your worth ☑

Project creator Pieter Thomas, a student at Howest Kortrijk University, needed to show off his skills by building a ‘something’ for his course. His inspiration?

I came up with this idea because I like to skate and cruise around. While I’m cruising, it would be handy to see how much distance I’ve travelled and see my speed.

So he decided to incorporate an odometer, a speedometer, and an RFID reader into a skateboard to produce this neat build.

Make and skate

While Pieter has an Arduino manage the onboard RFID reader, he’s put a Raspberry Pi 3 in charge of everything else, including the speed and distance readings taken with the help of a hall effect sensor (a transducer that uses magnetic fields to manage voltage output).

Speed and distance tracking Raspberry Pi skateboard

Pieter added the RFID reader to identify different users, with databases allowing for session data collection — perfect for time and speed challenges among friends!

Home-brew casing

All the electronics live in a Tupperware-like container that Pieter screwed to the bottom of the board. Holes in the deck display an LCD screen, a potentiometer, and a buzzer.

Speed and distance tracking Raspberry Pi skateboard

To allow speed and distance calculations, Pieter drilled a hole into one of the wheels and inserted a magnet. Once per wheel rotation, the hall effect sensor recognises the passing magnet. The build records the time taken between passes, computes the speed and distance covered, and shows them on the LCD screen.

Pieter’s Instructables project page goes into a lot more detail of how to build your own skate-o-meter. If you’ve used a Pi for your skateboarding project, make sure to let us know!

Skateboard + Pi

Other impressive Raspberry Pi–based board builds include Tim Maier’s motorised skateboard, aka the first blog post I ever wrote for Raspberry Pi, and Matt ‘The Raspberry Pi Guy’ Timmons-Brown’s 30kmph longboard, aka the project that resulted in this video of Raspberry Pi’s Director of Software Engineering:

How to build a competiton-ready Raspberry Pi robot

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/how-to-build-raspberry-pi-robot/

With the recent announcement of the 2019 Pi Wars dates, we’ve collected some essential online resources to help you get started in the world of competitive robots.

bbc robot wars raspberry pi robot

Robotics 101

Before you can strap chainsaws and flamethrowers to your robot, you need to learn some basics. Sorry.

As part of our mission to put digital making into the hands of people across the globe, the Raspberry Pi Foundation creates free project tutorials for hardware builds, Scratch projects, Python games, and more. And to get you started with robot building, we’ve put together a series of buggy-centric projects!



Begin with our Build a robot buggy project, where you’ll put together a simple buggy using motors, a Raspberry Pi 3, and a few other vital ingredients. From there, move on to the Remotely control your buggy tutorial to learn how to command your robot using an Android phone, a Google AIY Projects Voice Kit, or a home-brew controller. Lastly, train your robot to think for itself using our new Build a line-following robot project.

Prepare your buggy for battle

Put down the chainsaw — we’re not there yet!

raspberry pi robot

For issue 51, The MagPi commissioned ace robot builder Brian Cortiel to create a Build a remote control robot feature. The magazine then continued the feature in issue 52, adding a wealth of sensors to the robot. You can download both issues as free PDFs from The MagPi website. Head here for issue 51 and here for issue 52.

Pi Wars

To test robot makers’ abilities, previous Pi Wars events have included a series of non-destructive challenges: the balloon-popping Pi Noon, the minimal maze, and an obstacle course. Each challenge calls for makers to equip their robot with various abilities, such as speed, manoeuvrability, or line-following functionality.

Tanya Fish on Twitter

Duck shoot, 81 points! Nice one bub. #piwars https://t.co/UCSWaEOJh8

The Pi Wars team has shared a list of hints and tips from Brian Corteil that offer a great place to start your robotics journey. Moreover, many Pi Wars competitors maintain blogs about their build process to document the skills they learn, and the disasters along the way.

raspberry pi robot

This year’s blog category winner, David Pride’s Pi and Chips website, has a wealth of robot-making information.

If you’d like to give your robot a robust, good-looking body, check out PiBorg, robot-makers extraordinaire. Their robot chassis selection can help you get started if you don’t have access to a laser cutter or 3D printer, or if you don’t want to part with one of your Tupperware boxes to house your robot.

And now for the chainsaws!

Robot-building is a great way to learn lots of new skills, and we encourage everyone to give it a go, regardless of your digital making abilities. But please don’t strap chainsaws to your Raspberry Pi–powered robot unless you are trained in the ways of chainsaw-equipped robot building. The same goes for flamethrowers, cattle prods, and anything else that could harm another person, animal, or robot.

Pi Wars raspberry pi robot

Pi Wars 2019 will be taking place on 30 and 31 March in the Cambridge Computer Laboratory William Gates Building. If you’d like to take part, you can find more information here.

Using E Ink displays with a Raspberry Pi

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/using-e-ink-raspberry-pi/

Are you interested in using an E Ink display in your next Raspberry Pi project? Let us help you get started!

Raspberry Pi E Ink Displays

Weather and new display using a Raspberry Pi Zero and Kindle e-reader by Luke Haas

E Ink displays

E Ink displays are accessible, they don’t need a lot of power, and they can display content without any power connection whatsoever — think Amazon Kindle if you’ve only a vague knowledge of the technology.

E Ink displays work using negative and positive charges. They contain tiny microcapsules suspended in a liquid within a film layer. The microcapsules consist of negatively charged black particles and positively charged white particles. By applying the correct charge, you control whether the black or white particles come to the surface.

</e_ink_101_with_alex>

E Ink displays for your Raspberry Pi projects

So how and why would you use an E Ink display in your project? Simple! Aside from their low power consumption and indefinite display time, E Ink displays are relatively cheap, light, and interesting to look at. Plus, they’re easy to read in sunny conditions, which isn’t always true of LCD screens. And with e-readers now in their teens, there are plenty of forgotten devices collecting dust in drawers, ready to be repurposed.

Repurposing old e-readers

If you’ve ever tried to use the ‘experimental browser’ on a Kindle device, you’ll have found yourself transported back to the glory days of dial-up refresh rates and half-downloaded images. The only thing missing is the screeching connection tone. However, by connecting your Kindle to the same network as your Raspberry Pi, you can create a web page accessible to the e-reader to display data to your E Ink screen.

This bike computer by David Schneider makes use of that trick:

DIY: Build A Better Bike Computer

A Raspberry Pi and Kindle make vital information about your bicycle journey readable. Read more: http://spectrum.ieee.org/video/geek-life/hands-on/video-build-a-better-bike-computer

Secondhand e-readers are fairly easy to pick up from websites such as eBay, from your local carboot/yard sale, or from book-loving friends or family members. If you have one to hand and want to get making, you’ll find an abundance of tutorials for notification displays and low-power minimalist computers using e-readers.

Brand-new E Ink displays

If you want to buy a smaller display, or don’t have access to an old e-reader, you’ll find many online hobby retailers selling E Ink screens in several sizes and colours. The Pi Supply PaPiRus comes in many shapes and sizes as an easy-to-use Raspberry Pi HAT (Hardware Attached on Top). Simply push it in place on the GPIO pins, download the library to your Pi, and you’re good to go.

Raspberry Pi E Ink Displays

In case you’re looking to add a little more colour to your display, the Pimoroni red, white, and black Inky pHAT is an add-on designed for the Raspberry Pi Zero.

Raspberry Pi E Ink Displays

A quick and effective project for a smaller display like this is a Raspberry Pi Zero name badge, and we’ve seen our share of them at tech events and Picademy training sessions.

Brian Corteil 🤖 on Twitter

@MKRaspberryJam Yes, just like this one, pHat badge is a case for showing of your pHats, look mum no power!

Once you’ve programmed your Pi and updated your E Ink screen, you can detach it from the Pi and wow those you meet with your magic power-free digital name badge!

And if you buy yourself an E Ink HAT, you can even have a go at this Monzo-powered money tracker.

Raspberry Pi E Ink Monzo Display

Past predictions of Liz Upton

Back in 2013, our Director of Communication, Liz Upton, wrote a post about Max Ogden’s Kindleberry Pi build, commenting the following:

Here at the Foundation, we’re watching the development of e-ink products with great interest. At the moment it’s nigh-on impossible to buy an e-ink display as a consumer unless it comes bundled as part of an e-reader like a Kindle or a Nook; and that makes them very expensive. The technology has all kinds of potential for applications we want to see the Pi being used for: the low energy requirement makes an e-ink screen a perfect choice for places where you’re off the grid or reliant on solar power. We’re looking forward to seeing prices come down and displays becoming more easily available to consumers.

How lovely to be sat here in 2018, writing a post about the growing use of E Ink displays and the wide availability of the technology to hobbyists and digital makers! It shows how far the electronics industry for home builders has come, and we’re excited to see where it’s heading next.

A working original Doctor Who K-9 prop

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/k-9-working-doctor-who-prop/

When Abertay University purchased some unwanted Doctor Who props from the BBC in 2011, they could never have known that their future computer science student Gary Taylor would transform a water-damaged robot corpse into a working K-9, the cutest (and snarkiest) of all the Doctor’s companions.

K-9 Doctor Who Raspberry Pi Prop

K-9

If you’re unfamiliar with Doctor Who, you may not be aware of the Doctor’s robotic-canine best friend, K-9. I won’t wax lyrical about the long and winding history of this iconic science fiction character (though I could), but those of you who want to learn more can watch the video below.

History of K9 – History of Doctor Who

Hello and welcome to the Whoniverse and to another instalment of the History of Doctor Who series, this time I’m not looking at a universe conquering species but a tin dog. Yes the Doctor’s past travelling companion K9. There have been many versions of K9 and he has appeared alongside numerous Doctor’s and other companions.

Tl;dw: K-9 is basically a really clever, robotic dog invented in the year 5000.

Resurrecting a robotic dog

For his final-year dissertation, computer science student Gary Taylor decided to bring K-9 back to life, having discovered the prop damaged by a water leak in the university hackspace.

“I love robotics, I love programming, I love dogs, and I love Doctor Who.” Don’t we all, Gary. Don’t we all.
Image c/o The Courier

For his dissertation, titled Creating an Autonomous Robot Utilizing Raspberry Pi, Arduino, and Ultrasound Sensors for Mapping a Room, Gary used modern-day technology to rebuild K-9’s original and often unreliable radio-controlled electronics from the 1970s.

However, Gary’s K-9 is more than a simple remote-controlled robot. As the dissertation title states, the robot uses ultrasound sensors for room mapping, and this function is controlled by both an Arduino and Raspberry Pi.

A block diagram taken from Gary’s dissertation

An Arduino Mega 2560 controls the wheels and three ultrasound sensors located at the bottom of K-9’s body. It passes the sensor data to the onboard Raspberry Pi 3, and the Pi plots obstacles and walls to create a map of K-9’s surroundings.

The three ultrasonic sensors can be seen along the bottom of K-9’s body

The Raspberry Pi also connects to a smartphone via Bluetooth, where Gary runs a custome app to remotely control K-9 and view the map it creates.

More information? Affirmative!

The team at the Electronic Engineering Journal has written up a very thorough explanation of Gary’s dissertation. Those interested in the full details of the robot won’t be disappointed!

For a video of Gary and K-9 that refuses to embed itself in this blog post, head over to The Courier’s website.

And for more Doctor Who–related Raspberry Pi builds, check out Jeremy Lee’s remake of Captain Jack’s Vortex Manipulator, a synthesised rendition of the classic theme using a Raspberry Pi Zero, and a collection of builds and props in this Doctor Who roundup, including a sonic screwdriver, a Dalek, and a TARDIS in near-space.

Echoing the Newcastle of yesteryear with Pi-powered whistles

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/steve-messam-whistle/

Artist Steve Messam is celebrating the North of England’s historic role in railway innovation with 16 Raspberry Pi–controlled steam engine whistles around the city of Newcastle.

Steve Messam Raspberry Pi Whistle The Great Exhibition of the North

The Great Exhibition of the North

The Great Exhibition of the North is a summer-long celebration of the pioneering spirit of the North of England. Running over 80 days, the event will feature live performances, exhibitions, artworks, and displays of innovation from 22 June – 9 September 2018.

As part of the celebration, artist Steve Messam is introducing his Whistle project in Newcastle in honour of the North’s part in the innovation of the railway. “Listen out for the evocative sound of steam engine whistles once again echoing across the city of Newcastle,” states the project page of The Great Exhibition of the North. “The sound installation is designed to recall the role of the North in engineering and the invention of the railway, sparking memories and forging links between past and present.”

Whistle

Steve first developed the idea for Whistle as a pitch to the Loch Lomond and The Trossachs National Park back in 2014. He originally wanted to install a line of whistles along the 22-mile course of the old railway line between Callander and Glen Dochart, with whistles sounding off in one-second intervals, recreating the sound of the old line.

Below is a very nice roundup of the initial 2-mile test run, including the original whistle designs.

Fast forward to 2018 and The Great Exhibition of the North, where Steve is surrounding the city of Newcastle with 16 newly casted brass whistles. The new installation follows the old city wall of Newcastle, with each whistle sounding at exactly 1pm on every day of the exhibition.

Original plans for the whistle

The William Lane Foundry cast the 16 whistles to match a design by William Armstrong based on measurements of an original whistle held by the North East Locomotive Preservation Group.

Each unit is powered by solar panels and registers the time from the National Physical Laboratory’s atomic clock in London to ensure accurate timings. As a fallback in case of WiFi issues, the whistles are also linked to the clock set on the Raspberry Pi itself.

The more I think about it the more I really like that ‘Whistle’ only really exists for about 20 seconds each day.

For more information on Whistle, check out this wonderful article by the Teesdale Mercury. You can also find out more about Steve Messam projects, such as his paper bridge that can support the weight of a Land Rover, on his website or by following his Twitter account.

It is a truth universally acknowledged…that everyone wants their own Star Wars droid. If you’re now thinking “No, not me!”, then you obviously haven’t met the right droid yet. But Patrick ‘PatchBOTS‘ Stefanski has, and that droid is L3-37 from the newly released Solo: A Star Wars Story.

Release the droids

Visit your local maker event, such as Maker Faire, and you’re sure to meet at least one droid builder. Building a Star Wars droid is pretty much every maker’s dream, and YouTube droid-building sensation Patrick Stefanski is living that dream. On his Youtube channel PatchBOTS, Patrick is showcasing his maker chops with truly impressive recreations of characters such as BB-8 and our personal favourite, Chopper from Star Wars Rebels.

L3-37

Patrick’s new L3-37 build uses the free Alexa Voice Service and a Raspberry Pi 3 to augment a 3D-printed base model with robotics and AI.

He designed L3-37’s head based on press images and trailers, and then adjusted some of the visual aesthetic after watching the movie. When he realised that the Amazon Echo Dot he’d started the build with wouldn’t allow him to implement some of the features he had planned, including a unique wake word, Patrick decided to use a Raspberry Pi instead.

Solo Star Wars Story L3-37 droid PatchBOTs

A wake word is the word a home assistant uses to recognise that you’re addressing it. For Amazon Alexa, the standard wake words are ‘Alexa’, ‘Echo’, ‘Amazon’, and ‘computer’. While these are fine for standard daily use, Patrick wanted his droid to acknowledge its own name, L3-37. He also wanted to make L3-37 react with a voice response and movement whenever it heard its name. Using the Raspberry Pi enabled him to edit the home assistant code to include these functionalities, and in this way he made L3-37 truly come to life.

Build your own L3-37 home assistant

If you’d like to build your own L3-37 (and why wouldn’t you), Patrick is in the process of adding the complete set of instructions and code to his Github account. The 3D printer files are available now to get you started, along with the list of ingredients for the build, including servos, NeoPixels, and every propmaker’s staple: Rub n Buff.

If you want buy the parts for this project, why not use the affiliate links Patrick provides in the L3-37 video description to help him fund future projects? And while you’re there, leave a comment to show him some love for this incredible droid build, and also subscribe to his channel to see what he comes up with next.

Solo Star Wars Story L3-37 droid

We’re definitely going to be taking some of the lessons learned in this project to work on our own builds, and we hope you’ll do the same and share your work with us via social media.

Archimedes, the Google AIY Projects Vision familiar

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

hackster.io‘s ‘resident hardware nerd’ Alex Glow has gifted the world of makers with Archimedes, a shoulder-mounted owl that judges your emotions using the Google AIY Project Vision Kit.

Say Hi to Archimedes – the AI Robot Owl

Say hi to Archimedes – the robot owl with a Google AIY brain. Built with Raspberry Pi + Arduino! Here are some insights into pitfalls of the build process. I made this li’l guy to demo the AIY Vision Kit for Maker Faire 2018… but he’s not going away anytime soon!

Google AIY Project Kits

Google released the Pi-powered AIY Projects Voice Kit last year, providing the entire set of build ingredients with issue 57 of The MagPi Magazine. You loved it, we loved it, and later that year they followed up the Voice Kit’s success with the Vision Kit, also based on the Raspberry Pi.

google aiy vision kit

As the name indicates, the Voice Kit completes tasks in response to voice commands, just like Amazon Alexa or Google Home. The Vision Kit allows makers to experiment with neural networking to implement image recognition in their projects.

Planning for Maker Faire

When the hackster.io team was asked to contribute a project to Google’s stand at Maker Faire Bay Area this year, their in-house self-confessed hardware and robotics nerd Alex Glow took on the challenge.

I took a really, really long time to figure out what to build — what it would look like, how it would animate, how it would dispense the stickers…in the end, I went with this cute and fairly challenging design.

And so, Alex brought Archimedes the robotic owl into the world — and the world is a cuter place for it.

Archimedes the owl

Having set up the Google AIY Vision Kit — you can find Alex’s live build video here — she raided a HackerBox for a pan/tilt gimble. The gimble was far more robust than simple servos, and since Alex wanted to bring Archimedes to more events after Maker Faire, she needed something that would take the wear and tear.

it’ll be fun trying to explain this one // i tried: bit.ly/robotowl

337 Likes, 18 Comments – Alex Glow (@glowascii) on Instagram: “it’ll be fun trying to explain this one // i tried: bit.ly/robotowl”

For Maker Faire, she modified Archimedes to be a shoulder-mounted familiar, but Alex initially mounted him on a box that would open to reveal a prize if Archimedes detected a certain facial expression. For this, she introduced an Arduino into the mix, using the board to control three servos: two for the gimble and the third for the box lid.

Archimedes’s main objective is to hunt out faces and read their expressions. Because of this, his head is always moving so he can take in his surroundings like a real owl.

I combined the AIY Kit’s LED and Joy Detection demos (found in /gpiozero and /joy, respectively). I wanted to make the LED pin turn on when it finds a happy face, but weirdly, this code does the opposite. Someday, I will be enough of a software wizard to figure out why…

Alex designed the owl’s body using OnShape, with the intention of keeping the Raspberry Pi and AIY tech inside. Then she 3D printed the body using the Lulzbot Taz 6 and very hackster-blue filament.

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.

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

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.

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.

Mayank Sinha’s home security project

Post Syndicated from Helen Lynn original https://www.raspberrypi.org/blog/home-security/

Yesterday, I received an email from someone called Mayank Sinha, showing us the Raspberry Pi home security project he’s been working on. He got in touch particularly because, he writes, the Raspberry Pi community has given him “immense support” with his build, and he wanted to dedicate it to the commmunity as thanks.

Mayank’s project is named Asfaleia, a Greek word that means safety, certainty, or security against threats. It’s part of an honourable tradition dating all the way back to 2012: it’s a prototype housed in a polystyrene box, using breadboards and jumper leads and sticky tape. And it’s working! Take a look.

Asfaleia DIY Home Security System

An IOT based home security system. The link to the code: https://github.com/mayanksinha11/Asfaleia

Home security with Asfaleida

Asfaleia has a PIR (passive infrared) motion sensor, an IR break beam sensor, and a gas sensor. All are connected to a Raspberry Pi 3 Model B, the latter two via a NodeMCU board. Mayank currently has them set up in a box that’s divided into compartments to model different rooms in a house.

A shallow box divided into four labelled "rooms", all containing electronic components

All the best prototypes have sticky tape or rubber bands

If the IR sensors detect motion or a broken beam, the webcam takes a photo and emails it to the build’s owner, and the build also calls their phone (I like your ringtone, Mayank). If the gas sensor detects a leak, the system activates an exhaust fan via a small relay board, and again the owner receives a phone call. The build can also authenticate users via face and fingerprint recognition. The software that runs it all is written in Python, and you can see Mayank’s code on GitHub.

Of prototypes and works-in-progess

Reading Mayank’s email made me very happy yesterday. We know that thousands of people in our community give a great deal of time and effort to help others learn and make things, and it is always wonderful to see an example of how that support is helping someone turn their ideas into reality. It’s great, too, to see people sharing works-in-progress, as well as polished projects! After all, the average build is more likely to feature rubber bands and Tupperware boxes than meticulously designed laser-cut parts or expert joinery. Mayank’s YouTube channel shows earlier work on this and another Pi project, and I hope he’ll continue to document his builds.

So here’s to Raspberry Pi projects big, small, beginner, professional, endlessly prototyped, unashamedly bodged, unfinished or fully working, shonky or shiny. Please keep sharing them all!

3D-printed speakers from the Technical University of Denmark

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/technical-university-denmark-speakers/

Students taking Design of Mechatronics at the Technical University of Denmark have created some seriously elegant and striking Raspberry Pi speakers. Their builds are part of a project asking them to “explore, design and build a 3D printed speaker, around readily available electronics and components”.

The students have been uploading their designs, incorporating Raspberry Pis and HiFiBerry HATs, to Thingiverse throughout April. The task is a collaboration with luxury brand Bang & Olufsen’s Create initiative, and the results wouldn’t look out of place in a high-end showroom; I’d happily take any of these home.

Søren Qvist’s wall-mounted kitchen sphere uses 3D-printed and laser-cut parts, along with the HiFiBerry HAT and B&O speakers to create a sleek-looking design.

Otto Ømann’s group have designed the Hex One – a work-in-progress wireless 360° speaker. A particular objective for their project is to create a speaker using as many 3D-printed parts as possible.

Portable B&O-Create Speaker



“The design is supposed to resemble that of a B&O speaker, and from a handful of categories we chose to create a portable and wearable speaker,” explain Gustav Larsen and his team.

Oliver Repholtz Behrens and team have housed a Raspberry Pi and HiFiBerry HAT inside this this stylish airplay speaker. You can follow their design progress on their team blog.

B&O TILE



Tue Thomsen’s six-person team Mechatastic have produced the B&O TILE. “The speaker consists of four 3D-printed cabinet and top parts, where the top should be covered by fabric,” they explain. “The speaker insides consists of laser-cut wood to hold the tweeter and driver and encase the Raspberry Pi.”

The team aimed to design a speaker that would be at home in a kitchen. With a removable upper casing allowing for a choice of colour, the TILE can be customised to fit particular tastes and colour schemes.

Build your own speakers with Raspberry Pis

Raspberry Pi’s onboard audio jack, along with third-party HATs such as the HiFiBerry and Pimoroni Speaker pHAT, make speaker design and fabrication with the Pi an interesting alternative to pre-made tech. These builds don’t tend to be technically complex, and they provide some lovely examples of tech-based projects that reflect makers’ own particular aesthetic style.

If you have access to a 3D printer or a laser cutter, perhaps at a nearby maker space, then those can be excellent resources, but fancy kit isn’t a requirement. Basic joinery and crafting with card or paper are just a couple of ways you can build things that are all your own, using familiar tools and materials. We think more people would enjoy getting hands-on with this sort of thing if they gave it a whirl, and we publish a free magazine to help.

Raspberry Pi Zero AirPlay Speaker

Looking for a new project to build around the Raspberry Pi Zero, I came across the pHAT DAC from Pimoroni. This little add-on board adds audio playback capabilities to the Pi Zero. Because the pHAT uses the GPIO pins, the USB OTG port remains available for a wifi dongle.

This video by Frederick Vandenbosch is a great example of building AirPlay speakers using a Pi and HAT, and a quick search will find you lots more relevant tutorials and ideas.

Own your own working Pokémon Pokédex!

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/deep-learning-pokedex/

Squeal with delight as your inner Pokémon trainer witnesses the wonder of Adrian Rosebrock’s deep learning Pokédex.

Creating a real-life Pokedex with a Raspberry Pi, Python, and Deep Learning

This video demos a real-like Pokedex, complete with visual recognition, that I created using a Raspberry Pi, Python, and Deep Learning. You can find the entire blog post, including code, using this link: https://www.pyimagesearch.com/2018/04/30/a-fun-hands-on-deep-learning-project-for-beginners-students-and-hobbyists/ Music credit to YouTube user “No Copyright” for providing royalty free music: https://www.youtube.com/watch?v=PXpjqURczn8

The history of Pokémon in 30 seconds

The Pokémon franchise was created by video game designer Satoshi Tajiri in 1995. In the fictional world of Pokémon, Pokémon Trainers explore the vast landscape, catching and training small creatures called Pokémon. To date, there are 802 different types of Pokémon. They range from the ever recognisable Pikachu, a bright yellow electric Pokémon, to the highly sought-after Shiny Charizard, a metallic, playing-card-shaped Pokémon that your mate Alex claims she has in mint condition, but refuses to show you.

Pokemon GIF

In the world of Pokémon, children as young as ten-year-old protagonist and all-round annoyance Ash Ketchum are allowed to leave home and wander the wilderness. There, they hunt vicious, deadly creatures in the hope of becoming a Pokémon Master.

Adrian’s deep learning Pokédex

Adrian is a bit of a deep learning pro, as demonstrated by his Santa/Not Santa detector, which we wrote about last year. For that project, he also provided a great explanation of what deep learning actually is. In a nutshell:

…a subfield of machine learning, which is, in turn, a subfield of artificial intelligence (AI).While AI embodies a large, diverse set of techniques and algorithms related to automatic reasoning (inference, planning, heuristics, etc), the machine learning subfields are specifically interested in pattern recognition and learning from data.

As with his earlier Raspberry Pi project, Adrian uses the Keras deep learning model and the TensorFlow backend, plus a few other packages such as Adrian’s own imutils functions and OpenCV.

Adrian trained a Convolutional Neural Network using Keras on a dataset of 1191 Pokémon images, obtaining 96.84% accuracy. As Adrian explains, this model is able to identify Pokémon via still image and video. It’s perfect for creating a Pokédex – an interactive Pokémon catalogue that should, according to the franchise, be able to identify and read out information on any known Pokémon when captured by camera. More information on model training can be found on Adrian’s blog.

For the physical build, a Raspberry Pi 3 with camera module is paired with the Raspberry Pi 7″ touch display to create a portable Pokédex. And while Adrian comments that the same result can be achieved using your home computer and a webcam, that’s not how Adrian rolls as a Raspberry Pi fan.

Plus, the smaller size of the Pi is perfect for one of you to incorporate this deep learning model into a 3D-printed Pokédex for ultimate Pokémon glory, pretty please, thank you.

Tackling climate change and helping the community

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/fair-haven-weather-station/

In today’s guest post, seventh-grade students Evan Callas, Will Ross, Tyler Fallon, and Kyle Fugate share their story of using the Raspberry Pi Oracle Weather Station in their Innovation Lab class, headed by Raspberry Pi Certified Educator Chris Aviles.

Raspberry Pi Certified Educator Chris Aviles Innovation Lab Oracle Weather Station

United Nations Sustainable Goals

The past couple of weeks in our Innovation Lab class, our teacher, Mr Aviles, has challenged us students to design a project that helps solve one of the United Nations Sustainable Goals. We chose Climate Action. Innovation Lab is a class that gives students the opportunity to learn about where the crossroads of technology, the environment, and entrepreneurship meet. Everyone takes their own paths in innovation and learns about the environment using project-based learning.

Raspberry Pi Certified Educator Chris Aviles Innovation Lab Oracle Weather Station

Raspberry Pi Oracle Weather Station

For our climate change challenge, we decided to build a Raspberry Pi Oracle Weather Station. Tackling the issues of climate change in a way that helps our community stood out to us because we knew with the help of this weather station we can send the local data to farmers and fishermen in town. Recent changes in climate have been affecting farmers’ crops. Unexpected rain, heat, and other unusual weather patterns can completely destabilize the natural growth of the plants and destroy their crops altogether. The amount of labour output needed by farmers has also significantly increased, forcing farmers to grow more food on less resources. By using our Raspberry Pi Oracle Weather Station to alert local farmers, they can be more prepared and aware of the weather, leading to better crops and safe boating.

Raspberry Pi Certified Educator Chris Aviles Innovation Lab Oracle Weather Station

Growing teamwork and coding skills

The process of setting up our weather station was fun and simple. Raspberry Pi made the instructions very easy to understand and read, which was very helpful for our team who had little experience in coding or physical computing. We enjoyed working together as a team and were happy to be growing our teamwork skills.

Once we constructed and coded the weather station, we learned that we needed to support the station with PVC pipes. After we completed these steps, we brought the weather station up to the roof of the school and began collecting data. Our information is currently being sent to the Initial State dashboard so that we can share the information with anyone interested. This information will also be recorded and seen by other schools, businesses, and others from around the world who are using the weather station. For example, we can see the weather in countries such as France, Greece and Italy.

Raspberry Pi Certified Educator Chris Aviles Innovation Lab Oracle Weather Station

Raspberry Pi allows us to build these amazing projects that help us to enjoy coding and physical computing in a fun, engaging, and impactful way. We picked climate change because we care about our community and would like to make a substantial contribution to our town, Fair Haven, New Jersey. It is not every day that kids are given these kinds of opportunities, and we are very lucky and grateful to go to a school and learn from a teacher where these opportunities are given to us. Thanks, Mr Aviles!

Invent new sounds with Google’s NSynth Super

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/google-nsynth-super/

Discover new sounds and explore the role of machine learning in music production and sound research with the NSynth Super, an ongoing project from Google’s Magenta research team that you can build at home.

Google Open NSynth Super Testing

Uploaded by AB Open on 2018-04-17.

What is the NSynth Super?

Part of the ongoing Magenta research project within Google, NSynth Super explores the ways in which machine learning tools help artists and musicians be creative.

Google Nsynth Super Raspberry Pi

“Technology has always played a role in creating new types of sounds that inspire musicians — from the sounds of distortion to the electronic sounds of synths,” explains the team behind the NSynth Super. “Today, advances in machine learning and neural networks have opened up new possibilities for sound generation.”

Using TensorFlow, the Magenta team builds tools and interfaces that let  artists and musicians use machine learning in their work. The NSynth Super AI algorithm uses deep neural networking to investigate the character of sounds. It then builds new sounds based on these characteristics instead of simply mixing sounds together.

Using an autoencoder, it extracts 16 defining temporal features from each input. These features are then interpolated linearly to create new embeddings (mathematical representations of each sound). These new embeddings are then decoded into new sounds, which have the acoustic qualities of both inputs.

The team publishes all hardware designs and software that are part of their ongoing research under open-source licences, allowing you to build your own synth.

Build your own NSynth Super

Using these open-source tools, Andrew Black has produced his own NSynth Super, demoed in the video above. Andrew’s list of build materials includes a Raspberry Pi 3, potentiometers, rotary encoders, and the Adafruit 1.3″ OLED display. Magenta also provides Gerber files for you to fabricate your own PCB.

Google Nsynth Super Raspberry Pi

Once fabricated, the PCB includes a table of contents for adding components.

The build isn’t easy — it requires soldering skills or access to someone who can assemble PCBs. Take a look at Andrew’s blog post and the official NSynth GitHub repo to see whether you’re up to the challenge.
