The world’s first Raspberry Pi-powered Twitter-activated jelly bean-pooping unicorn

via Raspberry Pi

When eight-year-old Tru challenged the Kids Invent Stuff team to build a sparkly, pooping, rainbow unicorn electric vehicle, they did exactly that. And when Kids Invent Stuff, also known as Ruth and Shawn, got in contact with Estefannie Explains it All, their unicorn ended up getting an IoT upgrade…because obviously.

You tweet and the Unicorn poops candy! | Kids Invent Stuff

We bring kids’ inventions to life and this month we teamed up with fellow youtube Estefannie (from Estefannie Explains It All https://www.youtube.com/user/estefanniegg SHE IS EPIC!) to modify Tru’s incredible sweet pooping unicorn to be activated by the internet! Featuring the AMAZING Allen Pan https://www.youtube.com/channel/UCVS89U86PwqzNkK2qYNbk5A (Thanks Allen for your filming and tweeting!)

Kids Invent Stuff

If you’re looking for an exciting, wholesome, wonderful YouTube channel suitable for the whole family, look no further than Kids Invent Stuff. Challenging kids to imagine wonderful inventions based on monthly themes, channel owners Ruth and Shawn then make these kids’ ideas a reality. Much like the Astro Pi Challenge, Kids Invent Stuff is one of those things we adults wish existed when we were kids. We’re not jealous, we’re just…OK, we’re definitely jealous.

ANYWAY, when eight-year-old Tru’s sparkly, pooping, rainbow unicorn won the channel’s ‘crazy new vehicle’ challenge, the team got to work, and the result is magical.

Riding an ELECTRIC POOPING UNICORN! | Kids Invent Stuff

We built 8-year-old Tru’s sparkly, pooping, rainbow unicorn electric vehicle and here’s what happened when we drove it for the first time and pooped out some jelly beans! A massive THANK YOU to our challenge sponsor The Big Bang Fair: https://www.thebigbangfair.co.uk The Big Bang Fair is the UK’s biggest celebration of STEM for young people!

But could a sparkly, pooping, rainbow unicorn electric vehicle ever be enough? Is anything ever enough if it’s not connected to the internet? Of course not. And that’s where Estefannie came in.

At Maker Central in Birmingham earlier this year, the two YouTube teams got together to realise their shared IoT dream.

They ran out of chairs for their panel, so Allen had to improvise

With the help of a Raspberry Pi Zero W connected to the relay built into the unicorn, the team were able to write code that combs through Twitter, looking for mentions of @mythicalpoops. A positive result triggers the Raspberry Pi to activate the relay, and the unicorn lifts its tail to shoot jelly beans at passers-by.

You can definitely tell this project was invented by an eight-year-old, and we love it!

IoT unicorn

As you can see in the video above, the IoT upgrades to the unicorn allow Twitter users to control when the mythical beast poops its jelly beans. There are rumours that the unicorn may be coming to live with us at Pi Towers, but if these turn out to be true, we’ll ensure that this function is turned off. So no tweeting the unicorn!

You know what to do

Raspberry Pi 4: 48 hours later

via Raspberry Pi

“We’ve never felt more betrayed and excited at the same time,” admitted YouTubers 8 Bits and a Byte when I told them Raspberry Pi 4 would be out in June, going against rumours of the release happening at some point in 2020. Fortunately, everything worked in our favour, and we were able to get our new product out ahead of schedule.

So, while we calm down from the hype of Monday, here’s some great third-party content for you to get your teeth into.

YouTubers

A select few online content creators were allowed to get their hands on Raspberry Pi 4 before its release date, and they published some rather wonderful videos on the big day.

Office favourite Explaining Computers provided viewers with a brilliant explanation of the ins and outs of Raspberry Pi 4, and even broke their usually Sunday-only release schedule to get the video out to fans for launch day. Thanks, Chris!

Raspberry Pi 4 Model B

Raspberry Pi 4B review, including the hardware specs of this new single board computer, and a demo running the latest version of Raspbian. With thanks to the Raspberry Pi Foundation for supplying the board featured in this video.

Blitz City DIY offered viewers a great benchmark test breakdown, delving deeper into the numbers and what they mean, to show the power increase compared to Raspberry Pi 3B+.

A Wild Raspberry Pi 4 Appears: Hardware Specs, Benchmarks & First Impressions

The Raspberry Pi 4 B has been released into the wild much earlier than anticipated. I was able to receive a review sample so here are the hardware specs, some benchmarks comparing it to the Pi 3 B and Pi 3 B+ and finally some first impressions.

Curious about how these creators were able to get their hands on Raspberry Pi 4 prior to its release? This is legitimately how Estefannie bagged herself the computer pre-launch. Honest.

Three-factor authentication is the new two-factor authentication

via Raspberry Pi

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

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

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

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

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

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

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

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

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

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

Everyone should have a lair.

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.

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!

Today’s blog post is about Junie Genius

via Raspberry Pi

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

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

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

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

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

“New Junie!”

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

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

Watching VinylVideo with a Raspberry Pi A+

via Raspberry Pi

Play back video and sound on your television using your turntable and the VinylVideo converter, as demonstrated by YouTuber TechMoan.

VinylVideo – Playing video from a 45rpm record

With a VinylVideo convertor you can play video from a vinyl record played on a standard record player. Curiosity, tech-demo or art?

A brief history of VinylVideo

When demand for vinyl dipped in the early nineties, Austrian artist Gebhard Sengmüller introduced the world to his latest creation: VinylVideo. With VinylVideo you can play audio and visuals from an LP vinyl record using a standard turntable and a converter box plugged into a television set.

Gebhard Sengmüller original VinylVideo

While the project saw some interest throughout the nineties and early noughties, in the end only 20 conversion sets were ever produced.

However, when fellow YouTuber Randy Riddle (great name) got in touch with UK-based tech enthusiast TechMoan to tell him about a VinylVideo revival device becoming available, TechMoan had no choice but to invest.

Where the Pi comes in

After getting the VinylVideo converter box to work with an old Sony CRT unit, TechMoan decided to take apart the box to better understand how it works

You’ll notice a familiar logo at the top right there. Yes, it’s using a Raspberry Pi, a model A+ to be precise, to do the video decoding and output. It makes sense in a low-volume operation — use something that’s ready-made rather than getting a custom-made board done that you probably have to buy in batches of a thousand from China.

There’s very little else inside the sturdy steel casing, but what TechMoan’s investigation shows is that the Pi is connected to a custom-made phono preamp via USB and runs software written specifically for the VinylVideo conversion and playback.

Using Raspberry Pi for VinylVideo playback

For more information on the original project, visit the extremely dated VinylVideo website. And for more on the new product, you can visit the revival converter’s website.

Be sure to subscribe to TechMoan’s YouTube channel for more videos, and see how you can support him on Patreon.

And a huge thank you to David Ferguson for the heads-up! You can watch David talk about his own Raspberry Pi project, PiBakery, on our YouTube channel.
