Deter burglars with a Raspberry Pi chatbot

How to improve upon the standard burglar deterring method of leaving lights switched on? Dennis Mellican turned to Raspberry Pi for a much more effective solution. It actually proved too effective when a neighbour stopped by, but more on that in a bit.

Here you can see Dennis’s system in action scaring off a trespasser:

Good job, Raspberry Pi chatbots!

The burglar deterrent started out as Dennis’s regular home automation system. Not content with the current software offerings, and having worked in DevOps, Dennis decided to create his own solution. Enter Raspberry Pi (well, several of them).

Chatterboxes

Dennis has multiple Raspberry Pi–powered devices dotted around his home, doing things such as turning on lights, powering up a garden sprinkler, and playing fake dog barks on wireless speakers. All these burglar deterrents work together and are run by a chat bot.

Each Raspberry Pi controls a single automated item in Dennis’s home. All the Raspberry Pis communicate with each other via Slack. Dennis issues commands if he, for example, wants lights to turn on while he is away, but the Raspberry Pis can also talk to each other when a trigger event occurs, such as when a motion sensor is tripped.

Speaker, Google Chromecast, CCTV camera and Raspberry Pi

Google Chromecast enables ‘dumb’ speakers to be smart. Dennis has such speakers set up inside, close to windows at the front and back of the house, and they play an .mp3 file of a fake dog bark when commanded.

The security cameras Dennis uses in his home setup are a wireless CCTV variety, and the lights are a mix of TP-Link and Lifx smart bulbs.

Here’s all the Python code running Dennis’ entire security system.

Too effective?

Dennis’s smart system has backfired on him a few times. Once a neighbour visited while he was out and thought Dennis was rudely not answering the door, because she saw the lights go on inside, making it appear like he was home. Awkward.

The fake dog barking has also startled the postman and a few joggers — Dennis says it adds to the realism.

You’re cute, but you wreck stuff, so get out

The troupe of Raspberry Pis has also scared away an Australian possum (video above). These critters are notorious for making nests in roof cavities, so Dennis dodged another problematic home invasion there.

Future upgrades

Dennis is a maker after our own hearts when explaining where he’d like to go next with his anti-burglary build:

“I feel like Kevin McCallister from Home Alone, with these home security ‘traps’. I’m still waiting to catch the Wet Bandits for the sequel to this story. So far only stray cats have been caught by the sprinkler. Perhaps the next adventure of the chat bot is to order pizza and have Gangster ‘Johnny’ complete the transaction when the pizza delivery triggers the sensors.”

Go for it, Dennis!

RetroPie booze barrel

What do we want? Retro gaming, adult beverages, and our favourite Spotify playlist. When do we want them? All at the same time.

Luckily, u/breadtangle took to reddit to answer our rum-soaked prayers with this beautifully crafted beer barrel-cum-arcade machine-cum-drinks cabinet.

A beer barrel with drinks inside two opening doors cut into the front of the barrel and a retro arcade console serving as the lid of the barrel with joystick and buttons on a ledge in front
We approve of this drink selection

The addition of a sneaky hiding spot for your favourite tipple, plus a musical surprise, set this build apart from the popular barrel arcade projects we’ve seen before, like this one featured a few years back on the blog.

Retro gaming

A Raspberry Pi 3 Model B+ runs RetroPie, offering all sorts of classic games to entertain you while you sample from the grownup goodies hidden away in the drinks cabinet.

The maker’s top choice is Tetris Attack for the SNES.

Such a beautiful finish

Background music

What more could you want now you’ve got retro games and an elegantly hidden drinks cabinet at your fingertips? u/breadtangle‘s creation has another trick hidden inside its smooth wooden curves.

The Raspberry Pi computer used in this build also runs Raspotify, a Spotify Connect client for Raspberry Pi that allows you to stream your favourite tunes and playlists from your phone while you game.

You can set Raspotify to play via Bluetooth speakers, but if you’re using regular speakers and are after a quick install, whack this command in your Terminal:

curl -sL https://dtcooper.github.io/raspotify/install.sh | sh

Behind the scenes

u/breadtangle neatly tucked a pair of Logitech z506 speakers on the sides of the barrel, where they could be protected by the overhang of the glass screen cover.

Hardware

The build’s joysticks and buttons came from Amazon, and they’re set into an off-cut piece of kitchen countertop. The glass screen protector is another Amazon find and sits on a rubber car-door edge protector.

The screen itself is lovingly tilted towards the controls, to keep players’ necks comfortable, and u/breadtangle finished off the build’s look with a barstool to sit on while gaming.

We love it, but we have one very important question left…

Can we come round and play?

Get VMWare on Raspberry Pi

Hacking apart a sweet, innocent Raspberry Pi – who would do such a thing? Network Chuck, that’s who. But he has a very cool reason for it so, we’ll let him off the hook.

Subscribe to Network Chuck on YouTube

He’s figured out how to install VMware ESXi on Raspberry Pi, and he’s sharing the step-by-step process with you because he loves you. And us. We think. We hope.

Get cutting

In a nutshell, Chuck hacks apart a Raspberry Pi, turning it into three separate computers, each running different software at the same time. He’s a wizard.

VMware is cool because it’s Virtual Machine software big companies use on huge servers, but you can deploy it on one of our tiny devices and learn how to use it in the comfort of your own home if you follow Chuck’s instructions.

Raspberry Pi cut into three pieces with labels showing how powerful each bit is and what it's capable of
Useful labels explaining which bit of Raspberry Pi is capable of what

What do you need?

Make sure you’re up to date

So easy, it only takes 40 seconds to explain

Firstly, you need to make sure you’re running the latest version of Raspberry Pi OS. Chuck uses Raspberry Pi Imager to do this, and the video above shows you how to do the same.

Format your SD card

It’s teeny, but powerful

Then you’ll need to format your SD card ready for VMware ESXi. This can be done with Raspberry Pi Imager too. You’ll need to download these two things:

Chuck is the kind of good egg who walks you through how to do this on screen at this point in the project video.

VMware installation

Then you’ll need to create the VMWare Installer to install the actual software. It’s at this point your USB flash drive takes centre stage. Here’s everything you’ll need:

And this is the point in the video at which Chuck walks you through the process.

Once that’s all done, stick your USB flash drive into your Raspberry Pi and get going. You need to be quick off the mark for this bit – there’s some urgent Escape key pressing required, but don’t worry, Chuck walks you through everything.

Create a VM and expand your storage

Once you’ve followed all those steps, you will be up, running, and ready to go. The installation process only takes up the first 15 minutes of Chuck’s project video, and he spends the rest of his time walking you through creating your first VM and adding more storage.

Top job, Chuck.

Keep up with Chuck

These Furby-‘controlled’ Raspberry Pi-powered eyes follow you

Sam Battle aka LOOK MUM NO COMPUTER couldn’t resist splashing out on a clear Macintosh case for a new project in his ‘Cosmo’ series of builds, which inject new life into retro hardware.

AAGGGGHHHHHHH!

This time around, a Raspberry Pi, running facial recognition software, and one of our Camera Modules enable Furby-style eyes to track movement, detect faces, and follow you around the room.

Give LOOK MUM NO COMPUTER a follow on YouTube

He loves a good Furby does Sam. Has a whole YouTube playlist dedicated to projects featuring them. Seriously.

Sam got all the Raspberry Pi kit needed from Pimoroni

Our favourite bit of the video is when Sam meets Raspberry Pi for the first time, boots it up, and says:

“Wait, I didn’t know it was a computer. It’s an actual computer computer. What?!”

All the hacked, repurposed junky bits sit inside or are mounted on swish 3D-printed parts.

Add some joke shop chatterbox teeth, and you’ve got what looks like the innards of a Furby staring at you. See below for a harrowing snapshot of Zach’s ‘Furlexa’ project, featured on our blog last year. We still see it when we sleep.

It gets worse the more you look around

It wasn’t enough for Furby-mad Sam to have created a Furby look-a-like face-tracking robot, he needed to go further. Inside the clear Macintosh case, you can see a de-furred Furby skeleton atop a 3D-printed plinth, with redundant ribbon cables flowing from its eyes into the back of the face-tracking robot face, thus making it appear as though the Furby is the brains behind this creepy creation that is following your every move.

Hey in there. We see you! You dark lord of robo-controlling

Eventually, Sam’s Raspberry Pi–powered creation will be on display at the Museum of Everything Else, so you can go visit it and play with all the “obsolete and experimental technology” housed there. The museum is funded by the Look Mum No Computer Patreon page.

Raspberry Pi 400 for working and learning at home

Did you get Raspberry Pi 400 as a home learning or working device? We hope you’ve been getting on well with our affordable all-in-one computing solution.

If you’re a new user, here are some tips for you to get the most out of your brand-new Raspberry Pi 400.

Does *anyone’s* home office desk look this tidy?..

First things first!

Make sure your Raspberry Pi runs the newest version of the Raspberry Pi OS. Here is how (and here is a video preview of what the process looks like):

Screen grab of raspberry pi os being installed inline code

Open a terminal window by clicking on the Terminal icon in the top menu bar. Then type this command in the terminal window:

sudo apt update

Press Enter on the keyboard. Once the update is downloaded, type into the window:

sudo apt full-upgrade

Press Enter again. It is safe to just accept the default answer to any questions you are asked during the procedure by typing y and pressing Enter.

Now reboot your Raspberry Pi.

Videoconferencing, collaboration, files

With the newest version of Raspberry Pi OS installed, you can use the following applications in the Chromium browser:

Just log in with your username and password and start working or learning!

Raspberry Pi OS also has LibreOffice installed for working with text files, spreadsheets, and the like.

Printing on your Raspberry Pi

Go into the Preferences section in the main menu, and open Print Settings. This shows the system-config-printer dialog window, where you can do the usual things you’re familiar with from other operating systems: add new printers, remove old ones, set a printer as the default, and access the print queue for each printer.

Like most things in Linux-based operating systems such as Raspberry Pi OS, whether you can make your printer model work depends on user contributions; not every printer is supported yet. We’ve found that most networked printers work fine, while USB printers are a bit hit-and-miss. The best thing to do is to try it and see, and ask for help on our forums if your particular printer doesn’t seem to work.

Smart Fairy Tale

This is creepy, and we love it. OK, it’s not REALLY creepy, it’s just that some people have an aversion to dolls that appear to move of their own accord, due to a disturbing childhood experience — but enough about me.

Smart Fairy Tale is a whimsical, unique community project created by Berlin-based installation artist Niklas Roy and interaction designer Felix Fisgus.

Using a smartphone app, viewers determine which way a ball travels through transparent pipes, and depending on which light barriers the ball interrupts on its journey, various toys are animated to tell different stories.

The server of the installation is a Raspberry Pi 4. Via its GPIO pins, it controls the track switches and releases the ball.

The apparatus is full of toys donated by residents of Wolfsburg, Germany. The artists wanted local people to not only be able to operate the mechanical piece, but also to have a hand in creating it. Each animatronic toy is made as a separate module, controlled by its own Arduino Nano.

Smart Fairy Tale can be remotely controlled by viewers who want to check in on the toys they gifted to the installation, and by any other curious people elsewhere in the world.

Better yet, the stories the toys tell were devised by local school students. The artists showed the gifted toys to a few elementary school classes, and the students drew several stories featuring toys they liked. The makers then programmed the toys to match what the drawings said they could do. A servo here, a couple of LEDs there, and the students’ stories were brought to life.

Some drawings local children made suggesting storylines for each of the gifted toys

So what kind of stories did Wolfsburg’s finest come up with? One of the creators explains:

“There were a lot of scenes to interpret, like the blow-up love story, the chemtrail conspiracy, and the fossil fuel disaster, which culminates in a major traffic jam. The latter one even involved a laboratory for breeding synthetic dinosaurs by the use of renewable energies.”

Felix Fisgus

We LOVE it. Don’t tell me this isn’t creepy though…

You’ll find tonnes of extra technical specs and images in the project posts on both Felix and Niklas‘ websites.

Code your own Pipe Mania puzzler | Wireframe #46

Create a network of pipes before the water starts to flow in our re-creation of a classic puzzler. Jordi Santonja shows you how.

A screen grab of the game in motion
Pipe Mania’s design is so effective, it’s appeared in various guises elsewhere – even as a minigame in BioShock.

Pipe Mania, also called Pipe Dream in the US, is a puzzle game developed by The Assembly Line in 1989 for Amiga, Atari ST, and PC, and later ported to other platforms, including arcades. The player must place randomly generated sections of pipe onto a grid. When a counter reaches zero, water starts to flow and must reach the longest possible distance through the connected pipes.

Let’s look at how to recreate Pipe Dream in Python and Pygame Zero. The variable start is decremented at each frame. It begins with a value of 60*30, so it reaches zero after 30 seconds if our monitor runs at 60 frames per second. In that time, the player can place tiles on the grid to build a path. Every time the user clicks on the grid, the last tile from nextTiles is placed on the play area and a new random tile appears at the top of the next tiles. randint(2,8) computes a random value between 2 and 8.

Our Pipe Mania homage. Build a pipeline before the water escapes, and see if you can beat your own score.

grid and nextTiles are lists of tile values, from 0 to 8, and are copied to the screen in the draw function with the screen.blit operation. grid is a two-dimensional list, with sizes gridWidth=10 and gridHeight=7. Every pipe piece is placed in grid with a mouse click. This is managed with the Pygame functions on_mouse_move and on_mouse_down, where the variable pos contains the mouse position in the window. panelPosition defines the position of the top-left corner of the grid in the window. To get the grid cell, panelPosition is subtracted from pos, and the result is divided by tileSize with the integer division //. tileMouse stores the resulting cell element, but it is set to (-1,-1) when the mouse lies outside the grid.

The images folder contains the PNGs with the tile images, two for every tile: the graphical image and the path image. The tiles list contains the name of every tile, and adding to it _block or _path obtains the name of the file. The values stored in nextTiles and grid are the indexes of the elements in tiles.

wfmag46code
Here’s Jordi’s code for a Pipemania-style puzzler. To get it working on your system, you’ll need to install Pygame Zero. And to download the full code and assets, head here.

The image waterPath isn’t shown to the user, but it stores the paths that the water is going to follow. The first point of the water path is located in the starting tile, and it’s stored in currentPoint. update calls the function CheckNextPointDeleteCurrent, when the water starts flowing. That function finds the next point in the water path, erases it, and adds a new point to the waterFlow list. waterFlow is shown to the user in the draw function.

pointsToCheck contains a list of relative positions, offsets, that define a step of two pixels from currentPoint in every direction to find the next point. Why two pixels? To be able to define the ‘cross’ tile, where two lines cross each other. In a ‘cross’ tile the water flow must follow a straight line, and this is how the only points found are the next points in the same direction. When no next point is found, the game ends and the score is shown: the number of points in the water path, playState is set to 0, and no more updates are done.

Learning at home with the Raspberry Pi Foundation

As the UK — like many countries around the world — kicks off the new year with another national lockdown, meaning that millions of young people are unable to attend school, I want to share an update on how the Raspberry Pi Foundation is helping young people to learn at home.

Please help us spread the word to teachers, school leaders, governors, parents, and carers. Everything we are offering here is 100% free and the more people know about it, the more young people will benefit.

Supporting teachers and pupils 

Schools and teachers all over the world have been doing a heroic job over the past ten months, managing the transition to emergency remote teaching during the first round of lockdowns, supporting the most vulnerable pupils, dealing with uncertainty, changing the way that schools worked to welcome pupils back safely, helping pupils catch up with lost learning, and much, much more.

Both in my role as Chief Executive of the Raspberry Pi Foundation and as chair of governors at a state school here in Cambridge, I’ve seen first-hand the immense pressure that schools and teachers are under. I’ve also seen them display the most amazing resilience, commitment, and innovation. I want to say a huge thank you to all teachers and school staff for everything you’ve done and continue to do to help young people through this crisis. 

Here’s some of the resources and tools that we’ve created to help you continue to deliver a world-class computing education: 

  • The Teach Computing Curriculum is a comprehensive set of lesson plans for KS1–4 (learners aged 5–16) as well as homework, progression mapping, and assessment materials.
  • Working with the fabulous Oak National Academy, we’ve produced 100 hours of video for 300 video lessons based on the Teach Computing Curriculum.
  • Isaac Computer Science is our online learning platform for advanced computer science (A level, learners aged 16–18) and includes comprehensive, interactive materials and videos. It also allows you to set your learners self-marking questions. 

All of these resources are mapped to the English computing curriculum and produced as part of the National Centre for Computing Education. They are available for everyone, anywhere in the world, for free. 

Making something fun with code

Parents and carers are the other heroes of remote learning during lockdown. I know from personal experience that juggling work and supporting home learning can be really tough, and we’re all trying to find meaningful, fun alternatives to letting our kids binge YouTube or Netflix (other video platforms and streaming services are available).

That’s why we’ve been working really hard to provide parents and carers with easy, accessible ways for you to help your young digital makers to get creative with technology:

Getting computers into the hands of young people who need them 

One of the harsh lessons we learned last year was that far too many young people don’t have a computer for learning at home. There has always been a digital divide; the pandemic has just put it centre-stage. The good news is that the cost of solving this problem is now trivial compared to the cost of allowing it to persist.

That’s why the Raspberry Pi Foundation has teamed up with UK Youth and a network of grassroots youth and community organisations to get computers into the hands of disadvantaged young people across the UK.

A young person receives a Raspberry Pi kit to learn at home

For under £200 we can provide a vulnerable child with everything they need to learn at home, including a Raspberry Pi desktop computer, a monitor, a webcam, free educational software, and ongoing support from a local youth worker and the Foundation team. So far, we have managed to get 2000 Raspberry Pi computers into the hands of the most vulnerable young people in the UK. A drop in the ocean compared to the size of the problem, but a huge impact for every single young person and family.

This has only been possible thanks to the generous support of individuals, foundations, and businesses that have donated to support our work. If you’d like to get involved too, you can find out more here.

Meet team behind the mini Raspberry Pi–powered ISS

Quite possibly the coolest thing we saw Raspberry Pi powering this year was ISS Mimic, a mini version of the International Space Station (ISS). We wanted to learn more about the brains that dreamt up ISS Mimic, which uses data from the ISS to mirror exactly what the real thing is doing in orbit.

The ISS Mimic team’s a diverse, fun-looking bunch of people and they all made their way to NASA via different paths. Maybe you could see yourself there in the future too?

Dallas Kidd

His favorite projects include the ISS treadmill vibration isolation system and the shiny new docking system. He grew up on a small farm where his hands-on time with mechanical devices fueled his interest in engineering.

When not at work, he loves to brainstorm and create with his artist/engineer wife and their nerdy kids, or go on long family roadtrips—- especially to hike and kayak or eat ice cream. He’s also vice president of a local makerspace, where he leads STEM outreach and includes excess LEDs in all his builds.

Susan

A member of team ISS Mimic
Here’s Susan rocking some of those LED glasses and getting a good grip on ISS Mimic

Susan is a mechanical engineer and a 30+-year veteran of manned spaceflight operations.  She has worked the Space Shuttle Program for Payloads (middeck experiments and payloads deployed with the shuttle arm) starting with STS-30 and was on the team that deployed the Hubble Space Telescope.

She then transitioned into life sciences experiments, which led to the NASA Mir Program where she was on continuous rotation for three years to Russian Mission Control, supporting the NASA astronaut and science experiments onboard the space station as a predecessor to the ISS.

She currently works on the ISS Program (for over 20 years now), where she used to write procedures for on-orbit assembly of the Space Xtation and now writes installation procedures for on-orbit modifications like the docking adapter. She is also an artist and makes crosses out of found objects, and even used to play professional women’s football.

Raspberry Pi ‘Swear Bear’ keeps your potty mouth in check

Why use a regular swear jar to retrain your potty-mouthed brain when you can build a Swear Bear to help you instead?

Swear Bear listens to you. All the time. And Swear Bear can tell when a swear word is used. Swear Bear tells you off and saves all the swear words you said to the cloud to shame you. Swear Bear subscribes to the school of tough love.

Artificial intelligence

The Google AIY kit allows you to build your own natural language recogniser. This page shows you how to assemble the Voice HAT from the kit, and it also includes the code you’ll need to make your project capable of speech-to-text AI.

To teach Swear Bear the art of profanity detection, Swear Bear creators 8 Bits and a Byte turned to the profanity check Python library. You can find the info to install and use the library on this page, as well as info on how it works and why it’s so accurate.

You’ll hear at this point in the video that Swear Bear says “Oh dear” when a swear word is used within earshot.

Hardware

This project uses the the first version of Google’s AIY Voice Kit, which comes with a larger black AIY Voice HAT and is compatible with Raspberry Pi 3 Model B. The kit also includes a little Voice HAT microphone board.

Version 2 of the kit comprises the smaller Raspberry Pi Zero WH and a slimmer ‘Voice Bonnet’.

The microphone allows Swear Bear to ‘hear’ your speech, and through its speakers it can then tell you off for swearing.

All of hardware is squeezed into the stuffing-free bear once the text-to-speech and profanity detection software is working.

Babbage Bear hack?

Babbage the Bear

8 Bits and a Byte fan Ben Scarboro took to the comments on YouTube to suggest they rework one of our Babbage Bears into a Swear Bear. Babbage is teeny tiny, so maybe you would need to fashion a giant version to accomplish this. Just don’t make us watch while you pull out its stuffing.

Raspberry Pi Imager update

Just in time for the holidays, we’ve updated Raspberry Pi Imager to add some new functionality.

  • New submenu support: previous versions of Raspberry Pi Imager were limited to a single level of submenu. This limitation has been fixed so we can group images into different categories, such as general purpose operating systems, media players, and gaming and emulation.
  • New icons from our design team: easy on the eyes!
  • Version tracking: the menu file that Imager downloads from the Raspberry Pi website now includes an entry defining its latest version number, so in future, we can tell you when an updated Imager application is available.
  • Download telemetry: we’ve added some simple download telemetry to help us log how popular the various operating systems are.

You can go to our software page to download and install the new version 1.5 release of Raspberry Pi Imager and use it now.

We haven’t done telemetry in Imager before, and since people tend — rightly — to be concerned about applications gathering data, we want to explain exactly what we are doing and why: we’re logging which operating systems and categories people download, so we can make sure the most popular options are easy enough to find in Raspberry Pi Imager’s menu system.

We don’t record any personal data, such as your IP address; the information we collect allows us to see the number of downloads of each operating system over time, and nothing else. You’ll find more detailed information, including how to opt out of telemetry, in the Raspberry Pi Imager GitHub README.md.

You can see which OSes are most often downloaded too, on our stats page.

As you can see, the default recommended Raspberry Pi OS image is indeed the most downloaded option. The recently released Ubuntu Desktop for Raspberry Pi 4 and Raspberry Pi 400 is the most popular third-party operating system.

Add face recognition with Raspberry Pi | Hackspace 38

It’s hard to comprehend how far machine learning has come in the past few years. You can now use a sub-£50 computer to reliably recognise someone’s face with surprising accuracy.

Although this kind of computing power is normally out of reach of microcontrollers, adding a Raspberry Pi computer to your project with the new High Quality Camera opens up a range of possibilities. From simple alerting applications (‘Mum’s arrived home!’), to dynamically adjusting settings based on the person using the project, there’s a lot of fun to be had.

Here’s a beginner’s guide to getting face recognition up and running.

Face recognition using machine learning is hard work, so the latest, greatest Raspberry Pi 4 is a must

1. Prepare your Raspberry Pi
For face recognition to work well, we’re going to need some horsepower, so we recommend a minimum of Raspberry Pi 3B+, ideally a Raspberry Pi 4. The extra memory will make all the difference. To keep as much resource as possible available for our project, we’ve gone for a Raspberry Pi OS Lite installation with no desktop.

Make sure you’re on the network, have set a new password, enabled SSH if you need to, and updated everything with sudo apt -y update && sudo apt -y full-upgrade. Finally, go into settings by running sudo raspi-config and enable the camera in ‘Interfacing Options’.

2. Attach the camera
This project will work well with the original Raspberry Pi Camera, but the new official HQ Camera will give you much better results. Be sure to connect the camera to your Raspberry Pi 4 with the power off. Connect the ribbon cable as instructed in hsmag.cc/HQCameraGetStarted. Once installed, boot up your Raspberry Pi 4 and test the camera is working. From the command line, run the following:
raspivid -o test.h264 -t 10000
This will record ten seconds of video to your microSD card. If you have an HDMI cable plugged in, you’ll see what the camera can see in real-time. Take some time to make sure the focus is correct before proceeding.

3. Install dependencies
The facial recognition library we are using is one that has been maintained for many years by Adam Geitgey. It contains many examples, including Python 3 bindings to make it really simple to build your own facial recognition applications. What is not so easy is the number of dependencies that need to be installed first. There are way too many to list here, and you probably won’t want to type them out, so head over to hsmag.cc/FacialRec so that you can cut and paste the commands. This step will take a while to complete on a Raspberry Pi 4, and significantly longer on a Model 3 or earlier.

3. Install the libraries
Now that we have everything in place, we can install Adam’s applications and Python bindings with a simple, single command:
sudo pip3 install face_recognition
Once installed, there are some examples we can download to try everything out.
cd<br/>git clone --single-branch https://github.com/ageitgey/face_recognition.git<br/>In this repository is a range of examples showing the different ways the software can be used, including live video recognition. Feel free to explore and remix.

5. Example images
The examples come with a training image of Barack Obama. To run the example:
cd ./face_recognition/examples<br/>python3 facerec_on_raspberry_pi.py
On your smartphone, find an image of Obama using your favourite search engine and point it at the camera. Providing focus and light are good you will see:
“I see someone named Barack Obama!”
If you see a message saying it can’t recognise the face, then try a different image or try to improve the lighting if you can. Also, check the focus for the camera and make sure the distance between the image and camera is correct.

Who are you? What even is a name? Can a computer decide your identity?

6. Training time
The final step is to start recognising your own faces. Create a directory and, in it, place some good-quality passport-style photos of yourself or those you want to recognise. You can then edit the facerec_on_raspberry_pi.py script to use those files instead. You’ve now got a robust prototype of face recognition. This is just the beginning. These libraries can also identify ‘generic’ faces, meaning it can detect whether a person is there or not, and identify features such as the eyes, nose, and mouth. There’s a world of possibilities available, starting with these simple scripts. Have fun!

The Stargate | The MagPi 101

Fans of the Stargate SG-1 series, prepare to be inspired: a fellow aficionado has fashioned his own model of the show’s iconic portal. Nicola King takes an interstellar trip in the latest issue of The MagPi Magazine.

A mini version of the Stargate from TV sat on a table. Blue glowing light emits from the fake tunnel

When Kristian Tysse began making some projects on his new 3D printer, he soon became aware that the possibility of printing his own ‘working’ Stargate SG-1 model was within his grasp at last. “I suddenly realised I might now have enough knowledge about 3D printing, Raspberry Pi, motors, and programming to actually make a Stargate model of my own,” he tells us. “I wanted people who are familiar with the show to immediately know what it was, and tried to make it work as best I could, while staying as true as possible to the feeling and essence of the TV show.”

Raspberry Pi buried in the wires powering the mini stargate

Kristian also wanted to use a Raspberry Pi within this fully interactive, light-up, moving-parts project as “it is a powerful device with lots of flexibility. I do like that it functions as a full computer with an operating system with all the possibility that brings.”

Model minutiae

The back of the stargate controller with no lights on

You only have to look at the model to see just how much 3D printing was needed to get all of the parts ready to piece together, and Kristian created it in segments. But one of the key parts of his model is the DHD or Dial Home Device which viewers of the series will be familiar with. “The DHD functions as a USB keyboard and, when the keys are used, it sends signals to the (Python) program on Raspberry Pi that engages the different motors and lights in a proper Stargate way,” he enthuses. “If a correct set of keys/symbols are pressed on the DHD, the wormhole is established – illustrated on my Stargate with an infinity mirror effect.” 

“I wanted people who are familiar with the show to immediately know what it was”

Kristian Tysse

However, the DHD was a challenge, and Kristian is still tweaking it to improve how it works. He admits that writing the software for the project was also tricky, “but when I think back, the most challenging part was actually making it ‘functional’, and fitting all the wires and motors on it without destroying the look and shape of the Stargate itself.”

Dazzling detail

A close up of the stargate control panel with glowing orange touch buttons

Kristian admits to using a little artistic licence along the way, but he is keen to ensure the model replicates the original as far as possible. “I have taken a few liberties here and there. People on the social media channels are quick to point out differences between my Stargate and the one in the series. I have listened to most of those and done some changes. I will implement some more of those changes as the project continues,” he says. He also had to redesign the project several times, and had a number of challenges to overcome, especially in creating the seven lit, moving chevrons: “I tried many different approaches before I landed on the right one.”

The results of Kristian’s time-intensive labours are truly impressive, and show what you can achieve when you are willing to put in the hours and the attention to detail. Take a look at Kristian’s extremely detailed project page to see more on this super-stellar make.

Raspberry Pi and Google Code Next bring computer science to 1000 Chicago students

To round off Computer Science Education Week 2020, the Google Code Next team, working with the Raspberry Pi Foundation and some incredible volunteers in the Chicago area, helped over 400 Black and Latinx high school students get coding using Raspberry Pi 400. Here’s Omnia Saed with more.

In partnership with Google Code Next, the Raspberry Pi Foundation curated a computer science activity for over 400 Chicago Public Schools students. Over 1000 kits with the newly released Raspberry Pi 400 were sent to six public schools to mark the end of Computer Science Education Week (7-14 December).

Google Code Next

Google Code Next is a free computer science education program for Black and Latinx high school students. Between 2011 and 2018, Black and Hispanic college students each only made up 3 percent of computer science graduates; Code Next works to change that. The program provides students with the skills and inspiration needed for long and rewarding careers in computer science.

“We aim to provide Black and Latinx students with skills and technical social capital — that web of relationships you can tap into,” said Google Diversity STEM Strategist Shameeka Emanuel.

The main event

The virtual event brought over 80 Google volunteers, students and teachers together to create their very own “Raspimon”—a virtual monster powered by Raspberry Pi. For many students, it was their first time coding.

Matt Richardson, Executive Director of the Raspberry Pi Foundation North America, opened the event by telling students to share their work with family and friends.

“I hope you find new ways to solve problems or express yourselves creatively. More importantly, be sure to share what you create with someone you know – you might just spark curiosity in someone else,” he said.

In an interview with the Chicago Sun Times, Troy Williams, Chicago Public Schools interim director of computer science, explains, “Our students being able to have access to these Raspberry Pis and other resources supplements the learning they’re doing in the classrooms, and brings another level of engagement where they can create on their own. It really helps toward closing the digital divide and the learning gap as well.”

Want to join in with the fun? You’ll find a copy of the activity and curriculum on the Code Next website.

Supporting Raspberry Pi’s industrial customers

Raspberry Pi computers have always been used in a huge variety of settings, since the combination of low cost, high performance, and ease of use make it an ideal device for almost any application. We’ve seen a large proportion of sales go into the industrial market – businesses using Raspberry Pi, rather than educational settings or individual consumers. Today we’re announcing new support for this group of customers: a dedicated area of our website for industry, and our Raspberry Pi Approved Design Partners programme, connecting businesses that want to integrate Raspberry Pi into their products with hand-picked design partners who can help.

Screenshot from our Industrial web page featuring top performance stats

The industrial market for Raspberry Pi has grown over the years, and now represents around 44% of our annual total sales. We’ve seen this borne out with new releases of Raspberry Pi products: typically sales of a consumer product drop off once a new product is released, but we still see incredible sales of older models of Raspberry Pi. Our inference is that these are destined for embedded applications, where changing to the latest model is not practical. 

A new online resource for industry

To support Raspberry Pi’s industrial customers, we have developed a new, dedicated area of our website. Our For industry pages are the best place to go for industrial applications of Raspberry Pi. They provide access to the information and support you need when using our products in an industrial setting, with links to datasheets, compliance documents, and more.

As part of our commitment to industrial customers, we guarantee product lifetimes until at least 2026 on all products. We rarely ever end a product line – in fact, you can still buy Raspberry Pi 1 Model B+ from 2014. And we’ve made it easy for you to take a product through the necessary regulatory compliance steps, with the Raspberry Pi Integrator Programme.

Raspberry Pi Approved Design Partners

Along with our online resources for industry, we’re announcing a new programme to help customers who want to integrate Raspberry Pi into their products, and to recognise companies with specialist knowledge and proven expertise in designing with Raspberry Pi. The Raspberry Pi Approved Design Partners programme is a way of connecting trusted design consultancies with customers who need support designing Raspberry Pi computing solutions into their products. 

We’re launching with a select set of designers whom we already know and work with, and we hope to grow this group over the coming years. If your company provides hardware, software, or mechanical design services with Raspberry Pi, and you’d like us to promote your offering on our website, you can find out more about applying to become a Raspberry Pi Approved Design Partner.

If you have a product or a piece of work that uses Raspberry Pi, and you need technical assistance, Raspberry Pi Approved Design Partners have the capacity to provide you with effective help. All our Design Partners have been through a rigorous application process, and we will monitor them regularly for quality and ability. You can be confident that Raspberry Pi Approved Design Partners have the backing of Raspberry Pi, and have access to a deep level of technical knowledge and support within Raspberry Pi. 

We’re excited to help customers build fantastic products using Raspberry Pi, and we’re looking forward to working with a diverse range of designers across the world.

Adafruit guest post: Machine learning add-ons for Raspberry Pi

Hi folks, Ladyada here from Adafruit. The Raspberry Pi folks said we could do a guest post on our Adafruit BrainCraft HAT & Voice Bonnet, so here we go!

Adafruit BrainCraft HAT on top of a  Raspberry Pi
Adafruit BrainCraft HAT for Raspberry Pi

I’ve been engineering up a few Machine Learning devices that work with Raspberry Pi: BrainCraft HAT and the Voice Bonnet!

The idea behind the BrainCraft HAT is to enable you to “craft brains” for machine learning on the EDGE, with microcontrollers and microcomputers. On ASK AN ENGINEER, we chatted with Pete Warden, the technical lead of the mobile, embedded TensorFlow Group on Google’s Brain team about what would be ideal for a board like this.

BrainCraft HAT

And here’s what we designed! The BrainCraft HAT has a 240×240 TFT IPS display for inference output, slots for camera connector cable for imaging projects, a 5-way joystick, a button for UI input, left and right microphones, stereo headphone out, stereo 1W speaker out, three RGB DotStar LEDs, two 3-pin STEMMA connectors on PWM pins so they can drive NeoPixels or servos, and Grove/STEMMA/Qwiic I2C port.

This will let people build a wide range of audio/video AI projects while also allowing easy plug-in of sensors and robotics!

A controllable mini fan attaches to the bottom and can be used to keep your Raspberry Pi cool while it’s doing intense AI inference calculations. Most importantly, there’s an on/off switch that will completely disable the audio codec, so that when it’s off, there’s no way it’s listening to you.

Check it out here, and get all the learning guides.

Voice Bonnet

Adafruit Voice Bonnet for Raspberry Pi

Next up, the Adafruit Voice Bonnet for Raspberry Pi: two speakers plus two mics. Your Raspberry Pi computer is like an electronic brain — and with the Adafruit Voice Bonnet you can give it a mouth and ears as well! Featuring two microphones and two 1Watt speaker outputs using a high-quality I2S codec, this Raspberry Pi add-on will work with any Raspberry Pi with a 2×20 GPIO header, from Raspberry Pi Zero up to Raspberry Pi 4 and beyond (basically all models but the very first ones made).

The on-board WM8960 codec uses I2S digital audio for great quality recording and playback, so it sounds a lot better than the headphone jack on Raspberry Pi (or the no-headphone jack on Raspberry Pi Zero). We put ferrite beads and filter capacitors on every input and output to get the best possible performance, and all at a great price.

We specifically designed this bonnet for use when making machine learning projects such as DIY voice assistants. For example, see this guide on creating a DIY Google Assistant.

But you could do various voice-activated or voice recognition projects. With two microphones, basic voice position can be detected as well. Check it out here, and see the guides as well!

Four new products: IQaudio is now Raspberry Pi

We’re delighted to round off 2020 by welcoming four of the most popular IQaudio products to the Raspberry Pi fold. DAC+, DAC Pro, DigiAMP+, and Codec Zero will all be available to buy via our network of Raspberry Pi Approved Resellers.

We’ve had a busy 2020 here at Raspberry Pi. From the High Quality Camera to 8GB Raspberry Pi 4 to Compute Module 4 and Raspberry Pi 400, this year’s products have been under development for several years, and bringing them to market required us to build new capabilities in the engineering team. Building capabilities, rather than money or engineer time, is the real rate-limiting step for introducing new Raspberry Pi products.

One market we’ve never explored is hi-fi audio; this is a world unto itself, with a very demanding customer base, and we’ve never felt we had the capabilities needed to offer something distinctive. Over time, third parties have stepped in with a variety of audio I/O devices, amplifiers, and other accessories.

IQaudio

Founded by Gordon and Sharon Garrity together with Andrew Rankin in 2015, IQaudio was one of the first companies to recognise the potential of Raspberry Pi as a platform for hi-fi audio. IQaudio products are widely used by hobbyists and businesses (in-store audio streaming being a particularly popular use case). So when the opportunity arose to acquire IQaudio’s brand and product line late last year, we jumped at it.

Today we’re relaunching four of the most popular IQaudio products, at new affordable price points, via our network of Raspberry Pi Approved Resellers.

IQaudio DAC+

Priced at just $20, DAC+ is our lowest-cost audio output HAT, supporting 24‑bit 192kHz high-resolution digital audio. It uses a Texas Instruments PCM5122 DAC to deliver stereo analogue audio to a pair of phono connectors, and also provides a dedicated headphone amplifier.

IQaudio DAC+ HAT

IQaudio DAC Pro

Priced at $25, DAC Pro is our highest-fidelity audio output HAT. It supports the same audio input formats and output connectors as DAC+, but uses a Texas Instruments PCM5242 DAC, providing an even higher signal-to-noise ratio.

IQaudio DAC Pro HAT

In combination with an optional daughter board (due for relaunch in the first quarter of 2021), DAC Pro can support balanced output from a pair of XLR connectors.

IQaudio DigiAMP+

Where DAC+ and DAC Pro are designed to be used with an external amplifier, DigiAMP+ integrates a Texas Instruments TAS5756M digital-input amplifier directly onto the HAT, allowing you to drive a pair of passive speakers at up to 35W per channel. Combined with a Raspberry Pi board, it’s a complete hi-fi that’s the size of a deck of cards.

IQaudio DigiAMP+ HAT

DigiAMP+ is priced at $30, and requires an external 12-21V 3A DC power supply, sold separately. XP Power’s VEC65US19, available here and here, is a suitable supply.

IQaudio Codec Zero

Codec Zero is a $20 audio I/O HAT, designed to fit within the Raspberry Pi Zero footprint. It is built around a Dialog Semiconductor DA7212 codec and supports a range of input and output devices, from the built-in MEMS microphone to external mono electret microphones and 1.2W, 8 ohm mono speakers.

Unlike the other three products, which are in stock with our Approved Resellers now, Codec Zero will ship early in the New Year.

So there you have it. Four (nearly) new Raspberry Pi accessories, just in time for Christmas – hop over and buy yours now. This is the first time we’ve brought third-party products into our line-up like this; we’d like to thank the team at IQaudio for their help in making the transition.
