Playback your favourite records with Plynth

via Raspberry Pi

Use album artwork to trigger playback of your favourite music with Plynth, the Raspberry Pi–powered, camera-enhanced record stand.

Plynth Demo

This is “Plynth Demo” by Plynth on Vimeo, the home for high quality videos and the people who love them.

Record playback with Plynth

Plynth uses a Raspberry Pi and Pi Camera Module to identify cover artwork and play the respective album on your sound system, via your preferred streaming service or digital library.

As the project’s website explains, using Plynth is pretty simple. Just:

  • Place a n LP, CD, tape, VHS, DVD, piece of artwork – anything, really – onto Plynth
  • Plynth uses its built-in camera to scan and identify the work
  • Plynth starts streaming your music on your connected speakers or home stereo system

As for Plynth’s innards? The stand houses a Raspberry Pi 3B+ and Camera Module, and relies on “a combination of the Google Vision API and OpenCV, which is great because there’s a lot of documentation online for both of them”, states the project creator, sp_cecamp, on Reddit.

Other uses

Some of you may wonder why you wouldn’t have your records with your record player and, as such, use that record player to play those records. If you are one of these people, then consider, for example, the beautiful Damien Rice LP I own that tragically broke during a recent house move. While I can no longer play the LP, its artwork is still worthy of a place on my record shelf, and with Plynth I can still play the album as well.

In addition, instead of album artwork to play an album, you could use photographs, doodles, or type to play curated playlists, or, as mentioned on the website, DVDs to play the movies soundtrack, or CDs to correctly select the right disc in a disc changer.

Convinced or not, I think what we can all agree on is that Plynth is a good-looking bit of kit, and at Pi Towers look forward to seeing where they project leads.

Penguin Watch — Pi Zeros and Camera Modules in the Antarctic

via Raspberry Pi

Long-time readers will remember Penguin Lifelines, one of our very favourite projects from back in the mists of time (which is to say 2014 — we have short memories around here).

Penguins

Click on penguins for fun and conservation

Penguin Lifelines was a programme run by the Zoological Society of London, crowdsourcing the tracking of penguin colonies in Antarctica. It’s since evolved into something called Penguin Watch, now working with the World Wildlife Fund (WWF) and British Antarctic Survey (BAS). It’s citizen science on a big scale: thousands of people from all over the world come together on the internet to…click on penguins. By counting the birds in their colonies, users help penguinologists measure changes in the birds’ behaviour and habitat, and in the larger ecosystem, thus assisting in their conservation.

The penguin people say this about Penguin Watch:

Some of these colonies are so difficult to get to that they haven’t been visited for 50 years! The images contain unprecedented detail, giving us the opportunity to gather new data on the number of penguins in the region. This information will help us understand how they are being affected by climate change, the potential impact of local fisheries, and how we can help conserve these incredible species.

Pis in the coldest, wildest place

And what are those special cameras? The static ones providing time-lapse images are Raspberry Pi Camera Modules, mounted on Raspberry Pi Zeros, and we’re really proud to see just how robust they’ve been in the face of Antarctic winters.

Alasdair Davies on Twitter

Success! The @arribada_i timelapse @Raspberry_Pi Zero cameras built for @penguin_watch survived the Antarctic winter! They captured these fantastic photos of a Gentoo penguin rookery for https://t.co/MEzxbqSyc1 #WorldPenguinDay 🐧@helenlynn @philipcolligan https://t.co/M0TK5NLT6G

These things are incredibly tough. They’re the same cameras that Alasdair and colleagues have been sticking on turtles, at depths of down to 500m; I can’t think of a better set of tests for robustness.

Want to get involved? Head over to Penguin Watch, and get clicking! We warn you, though — it’s a little addictive.

Raspberry Pi captures a Soyuz in space!

via Raspberry Pi

So this happened. And we are buzzing!

You’re most likely aware of the Astro Pi Challenge. In case you’re not, it’s a wonderfully exciting programme organised by the European Space Agency (ESA) and us at Raspberry Pi. Astro Pi challenges European young people to write scientific experiments in code, and the best experiments run aboard the International Space Station (ISS) on two Astro Pi units: Raspberry Pi 2s and Sense HATs encased in flight-grade aluminium spacesuits.

It’s very cool. So, so cool. As adults, we’re all extremely jealous that we’re unable to take part. We all love space and, to be honest, we all want to be astronauts. Astronauts are the coolest.

So imagine our excitement at Pi Towers when ESA shared this photo on Friday:

This is a Soyuz vehicle on its way to dock with the International Space Station. And while Soyuz vehicles ferry between earth and the ISS all the time, what’s so special about this occasion is that this very photo was captured using a Raspberry Pi 2 and a Raspberry Pi Camera Module, together known as Izzy, one of the Astro Pi units!

So if anyone ever asks you whether the Raspberry Pi Camera Module is any good, just show them this photo. We don’t think you’ll need to provide any further evidence after that.

Hacking an Etch-A-Sketch with a Raspberry Pi and camera: Etch-A-Snap!

via Raspberry Pi

Kids of the 1980s, rejoice: the age of the digital Etch-A-Sketch is now!

What is an Etch-A-Sketch

Introduced in 1960, the Etch-A-Sketch was invented by Frenchman André Cassagnes and manufactured by the Ohio Art Company.

The back of the Etch-A-Sketch screen is covered in very fine aluminium powder. Turning one of the two directional knobs runs a stylus across the back of the screen, displacing the powder and creating a dark grey line visible in the front side.

can it run DOOM?

yes

The Etch-A-Sketch was my favourite childhood toy. So you can imagine how excited I was to see the Etch-A-Snap project when I logged into Reddit this morning!

Digital Etch-A-Sketch

Yesterday, Martin Fitzpatrick shared on Reddit how he designed and built Etch-A-Snap, a Raspberry Pi Zero– and Camera Module–connected Etch-A-Sketch that (slowly) etches photographs using one continuous line.

Etch-A-Snap is (probably) the world’s first Etch-A-Sketch Camera. Powered by a Raspberry Pi Zero (or Zero W), it snaps photos just like any other camera, but outputs them by drawing to an Pocket Etch-A-Sketch screen. Quite slowly.

Unless someone can show us another Etch-A-Sketch camera like this, we’re happy to agree that this is a first!

Raspberry Pi–powered Etch-A-Sketch

Powered by four AA batteries and three 18650 LiPo cells, Etch-A-Snap houses the $5 Raspberry Pi Zero and two 5V stepper motors within a 3D-printed case mounted on the back of a pocket-sized Etch-A-Sketch.

Photos taken using the Raspberry Pi Camera Module are converted into 1-bit, 100px × 60px, black-and-white images using Pillow and OpenCV. Next, these smaller images are turned into plotter commands using networkx. Finally, the Raspberry Pi engages the two 5V stepper motors to move the Etch-A-Sketch control knobs, producing a sketch within 15 minutes to an hour, depending on the level of detail in the image.

Build your own Etch-A-Snap

On his website, Martin goes into some serious detail about Etch-A-Snap, perfect for anyone interested in building their own, or in figuring out how it all works. You’ll find an overview with videos, along with breakdowns of the build, processing, drawing, and plotter.

SelfieBot: taking and printing photos with a smile

via Raspberry Pi

Does your camera giggle and smile as it takes your photo? Does your camera spit out your image from a thermal printer? No? Well, Sophy Wong’s SelfieBot does!

Raspberry Pi SelfieBot: Selfie Camera with a Personality

SelfieBot is a project Kim and I originally made for our booth at Seattle Mini Maker Faire 2017. Now, you can build your own! A full tutorial for SelfieBot is up on the Adafruit Learning System at https://learn.adafruit.com/raspberry-pi-selfie-bot/ This was our first Raspberry Pi project, and is an experiment in DIY AI.

Pasties, projects, and plans

Last year, I built a Raspberry Pi photobooth for a friend’s wedding, complete with a thermal printer for instant printouts, and a Twitter feed to keep those unable to attend the event in the loop. I called the project PastyCam, because I built it into the paper mache body of a Cornish pasty, and I planned on creating a tutorial blog post for the build. But I obviously haven’t. And I think it’s time, a year later, to admit defeat.

The wedding was in Cornwall, so the Cornish pasty totally makes sense, alright?

But lucky for us, Sophy Wong has gifted us all with SelfieBot.

Sophy Wong

If you subscribe to HackSpace magazine, you’ll recognise Sophy from issue 4, where she adorned the cover, complete with glowing fingernails. And if you’re like me, you instantly wanted to be her as soon as you saw that image.

SelfieBot Raspberry Pi Camera

Makers should also know Sophy from her impressive contributions to the maker community, including her tutorials for Adafruit, her YouTube channel, and most recently her work with Mythbusters Jr.

Filming for #MythbustersJr is wrapped, and I’m heading home to Seattle. What an incredible summer filled with amazing people. I’m so inspired by every single person, crew and cast, on this show, and I’ll miss you all until our paths cross again someday 😊

SelfieBot at MakerFaire

I saw SelfieBot in passing at Maker Faire Bay Area earlier this year. Yet somehow I managed to not introduce myself to Sophy and have a play with her Pi-powered creation. So a few weeks back at World Maker Faire New York, I accosted Sophy as soon as I could, and we bonded by swapping business cards and Pimoroni pins.

Creating SelfieBot

SelfieBot is more than just a printing photo booth. It giggles, it talks, it reacts to movement. It’s the robot version of that friend of yours who’s always taking photos. Always. All the time, Amy. It’s all the time! *ahem*

SelfieBot Raspberry Pi Camera

SelfieBot consists of a Raspberry Pi 2, a Pi Camera Module, a 5″ screen, an accelerometer, a mini thermal printer, and more, including 3D-printed and laser-cut parts.

sophy wong on Twitter

Getting SelfieBot ready for Maker Faire Bay Area next weekend! Super excited to be talking on Sunday with @kpimmel – come see us and meet SelfieBot!

If you want to build your own SelfieBot — and obviously you do — then you can find a complete breakdown of the build process, including info on all parts you’ll need, files for 3D printing, and so, so many wonderfully informative photographs, on the Adafruit Learning System!
