Get VMWare on Raspberry Pi

Post Syndicated from Ashley Whittaker original https://www.raspberrypi.org/blog/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.

Our poor sweet baby 😮

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.

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

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

Post Syndicated from Ashley Whittaker original https://www.raspberrypi.org/blog/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.

Black AIY HAT stuck on top of a Raspberry Pi

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.

Personal Raspberry Pi music streamer

Post Syndicated from Ashley Whittaker original https://www.raspberrypi.org/blog/personal-raspberry-pi-music-streamer/

Mike Perez from Audio Arkitekts took to YouTube to show you how to build your own music streamer using a Raspberry Pi. Haters of Bluetooth and RCA plugs, he’s done this for you.

Mike reports a “substantial difference in sound quality” compared to his previous setup (the aforementioned and reviled Bluetooth and RCA plug options).

This project lets you use a Raspberry Pi as a music player and control it from your mobile phone.

Hardware

Unboxing the Argon Neo Raspberry Pi Bundle

Mike started out with an $80 Argon Neo Raspberry Pi Bundle, which includes a Raspberry Pi 4 Model B. He made a separate video to show you how to put everything together.

This bundle comes with a nice, sleek case, so your music player can be on display discreetly.

Pretty case

Not sure about spending $80 on this kit? In the project video, Mike says it’s “totally, totally worth it” — partly due to the quality of the case.

Software

Mike grabbed a compatible Volumio image from Volumio’s ‘Get Started’ page and flashed it onto Raspberry Pi with Etcher.

Volumio app in action

You can use an Ethernet cable, but Mike wanted to utilise Raspberry Pi 4’s wireless connectivity to boot the Volumio app. This way, the Raspberry Pi music player can be used anywhere in the house, as it’ll create its own wireless hotspot within your home network called ‘Volumio’.

Eew! No more direct audio connection to your phone to listen to music.

You’ll need a different version of the Volumio app depending on whether you have an Android phone or iPhone. Mike touts the app as “super easy, really robust”. You just select the music app you usually use from the ‘Plugins’ section of the Volumio app, and all your music, playlists, and cover art will be there ready for you once downloaded.

And that’s basically it. Just connect to the Volumio OS via the app and tell your Raspberry Pi what to play.

Amp it up

To get his new music player booming all around the house, Mike used a Starke Sound AD4, which you can watch him unbox and review.

What kind of amplification system have you got paired up with your Raspberry Pi–powered music player?

Hire Raspberry Pi as a robot sous-chef in your kitchen

Post Syndicated from Ashley Whittaker original https://www.raspberrypi.org/blog/hire-raspberry-pi-as-a-robot-sous-chef-in-your-kitchen/

Design Engineering student Ben Cobley has created a Raspberry Pi–powered sous-chef that automates the easier pan-cooking tasks so the head chef can focus on culinary creativity.

Ben named his invention OnionBot, as the idea came to him when looking for an automated way to perfectly soften onions in a pan while he got on with the rest of his dish. I have yet to manage to retrieve onions from the pan before they blacken so… *need*.

OnionBot robotic sous-chef set up in a kitchen
The full setup (you won’t need a laptop while you’re cooking, so you’ll have counter space)

A Raspberry Pi 4 Model B is the brains of the operation, with a Raspberry Pi Touch Display showing the instructions, and a Raspberry Pi Camera Module keeping an eye on the pan.

OnionBot robotic sous-chef hardware mounted on a board
Close up of the board-mounted hardware and wiring

Ben’s affordable solution is much better suited to home cooking than the big, expensive robotic arms used in industry. Using our tiny computer also allowed Ben to create something that fits on a kitchen counter.

OnionBot robotic sous-chef hardware list

What can OnionBot do?

  • Tells you on-screen when it is time to advance to the next stage of a recipe
  • Autonomously controls the pan temperature using PID feedback control
  • Detects when the pan is close to boiling over and automatically turns down the heat
  • Reminds you if you haven’t stirred the pan in a while
OnionBot robotic sous-chef development stages
Images from Ben’s blog on DesignSpark

How does it work?

A thermal sensor array suspended above the stove detects the pan temperature, and the Raspberry Pi Camera Module helps track the cooking progress. A servo motor controls the dial on the induction stove.

Labelling images to train the image classifier

No machine learning expertise was required to train an image classifier, running on Raspberry Pi, for Ben’s robotic creation; you’ll see in the video that the classifier is a really simple drag-and-drop affair.

Ben has only taught his sous-chef one pasta dish so far, and we admire his dedication to carbs.

Screenshot of the image classifier of OnionBot robotic sous-chef
Training the image classifier to know when you haven’t stirred the pot in a while

Ben built a control panel for labelling training images in real time and added labels at key recipe milestones while he cooked under the camera’s eye. This process required 500–1000 images per milestone, so Ben made a LOT of pasta while training his robotic sous-chef’s image classifier.

Ben open-sourced this project so you can collaborate to suggest improvements or teach your own robot sous-chef some more dishes. Here’s OnionBot on GitHub.

YouTuber Jeff Geerling reviews Raspberry Pi Compute Module 4

Post Syndicated from Ashley Whittaker original https://www.raspberrypi.org/blog/youtuber-jeff-geerling-reviews-raspberry-pi-compute-module-4/

We love seeing how quickly our community of makers responds when we drop a new product, and one of the fastest off the starting block when we released the new Raspberry Pi Compute Module 4 on Monday was YouTuber Jeff Geerling.

Jeff Geerling

We made him keep it a secret until launch day after we snuck one to him early so we could see what one of YouTube’s chief advocates for our Compute Module line thought of our newest baby.

So how does our newest board compare to its predecessor, Compute Module 3+? In Jeff’s first video (above) he reviews some of Compute Module 4’s new features, and he has gone into tons more detail in this blog post.

Jeff also took to live stream for a Q&A (above) covering some of the most asked questions about Compute Module 4, and sharing some more features he missed in his initial review video.

His next video (above) is pretty cool. Jeff explains:

“Everyone knows you can overclock the Pi 4. But what happens when you overclock a Compute Module 4? The results surprised me!”

Jeff Geerling

And again, there’s tons more detail on temperature measurement, storage performance, and more on Jeff’s blog.

Top job, Jeff. We have our eyes on your channel for more videos on Compute Module 4, coming soon.

If you like what you see on his YouTube channel, you can also sponsor Jeff on GitHub, or support his work via Patreon.

Be a better Scrabble player with a Raspberry Pi High Quality Camera

Post Syndicated from Ashley Whittaker original https://www.raspberrypi.org/blog/be-a-better-scrabble-player-with-a-raspberry-pi-high-quality-camera/

One of our fave makers, Wayne from Devscover, got a bit sick of losing at Scrabble (and his girlfriend was likely raging at being stuck in lockdown with a lesser opponent). So he came up with a Raspberry Pi–powered solution!

Using a Raspberry Pi High Quality Camera and a bit of Python, you can quickly figure out the highest-scoring word your available Scrabble tiles allow you to play.

Hardware

  • Raspberry Pi 3B
  • Compatible touchscreen
  • Raspberry Pi High Quality Camera
  • Power supply for the touchscreen and Raspberry Pi
  • Scrabble board

You don’t have to use a Raspberry Pi 3B, but you do need a model that has both display and camera ports. Wayne also chose to use an official Raspberry Pi Touch Display because it can power the computer, but any screen that can talk to your Raspberry Pi should be fine.

Software

Firstly, the build takes a photo of your Scrabble tiles using raspistill.

Next, a Python script processes the image of your tiles and then relays the highest-scoring word you can play to your touchscreen.

The key bit of code here is twl, a Python script that contains every possible word you can play in Scrabble.

From 4.00 minutes into his build video, Wayne walks you through what each bit of code does and how he made it work for this project, including how he installed and used the Scrabble dictionary.

Fellow Scrabble-strugglers have suggested sneaky upgrades in the comments of Wayne’s YouTube video, such having the build relay answers to a more discreet smart watch.

No word yet on how the setup deals with the blank Scrabble tiles; those things are like gold dust.

In case you haven’t met the Raspberry Pi High Quality Camera yet, Wayne also did this brilliant unboxing and tutorial video for our newest piece of hardware.

Wes’s wonderful Minecraft user notification display

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/wess-wonderful-minecraft-user-notification-display/

This Minecraft sign uses a Raspberry Pi to notify you when, and how many of, your friends are logged into your dedicated Minecraft server.

Let’s start by pointing out how wonderfully nostalgic many of Wes ‘Geeksmithing’ Swain’s projects are. From his Raspberry Pi–housing cement Thwomp that plays his favourite Mario games to The NES Project, his NES replica unit with a built-in projector — Wes makes the things we wished for as kids.

The NES Project covered in HackSpace magazine

We honestly wouldn’t be surprised if his next project is a remake of Duckhunt with servo-controlled ducks, or Space Invaders but it’s somehow housed in a flying space invader that shoots back with lasers. Honestly, at this point, we wouldn’t put it past him.

Making the Minecraft friend notification display

In the video, Wes covers the project in two parts. Firstly, he shows off the physical build of making the sign, including laser-cut acrylic front displayed with controllable LED lights, a Raspberry Pi Zero, and the wooden framing.

Secondly, he moves on to the code, in which he uses mcstatus, a Python class created by Minecraft’s Technical Director Nathan Adams that can be used to query servers for information. In this instance, Wes is using mcstatus to check for other players on his group’s dedicated Mincecraft server, but the class can also be used to gather mod information. You can find mcstatus on GitHub.

Each friend is assigned a letter that illuminates if they’re online.

Lucky for Wes, he has the same number of friends on his server as the number of letters in ‘Minecraft’, so for every friend online, he’s programmed the display to illuminate a letter of the Minecraft logo. And while the server is empty, he can also set the display to run through various light displays, including this one, a dedication to the new Minecraft Nether update.

If you’d like to try making this project yourself, you can: Wes goes into great detail in his video, and the code for the project can be found on his GitHub account.

And while we have your attention, be sure to subscribe to Geeksmithing on YouTube and show him some love for such a great project.

Fix slow Nintendo Switch play with your Raspberry Pi

Post Syndicated from Ashley Whittaker original https://www.raspberrypi.org/blog/fix-slow-nintendo-switch-play-with-your-raspberry-pi/

Is your Nintendo Switch behaving more like a Nintendon’t due to poor connectivity? Well, TopSpec (hosted Chris Barlas) has shared a brilliant Raspberry Pi-powered hack on YouTube to help you fix that.

 

Here’s the problem…

When you play Switch online, the servers are peer-to-peer. The Switches decide which Switch’s internet connection is more stable, and that player becomes the host.

However, some users have found that poor internet performance causes game play to lag. Why? It’s to do with the way data is shared between the Switches, as ‘packets’.

 

What are packets?

Think of it like this: 200 postcards will fit through your letterbox a few at a time, but one big file wrapped as a parcel won’t. Even though it’s only one, it’s too big to fit. So instead, you could receive all the postcards through the letterbox and stitch them together once they’ve been delivered.

Similarly, a packet is a small unit of data sent over a network, and packets are reassembled into a whole file, or some other chunk of related data, by the computer that receives them.

Problems arise if any of the packets containing your Switch game’s data go missing, or arrive late. This will cause the game to pause.

Fix Nintendo Switch Online Lag with a Raspberry Pi! (Ethernet Bridge)

Want to increase the slow internet speed of your Nintendo Switch? Having lag in games like Smash, Mario Maker, and more? Well, we decided to try out a really…

Chris explains that games like Call of Duty have code built in to mitigate the problems around this, but that it seems to be missing from a lot of Switch titles.

 

How can Raspberry Pi help?

The advantage of using Raspberry Pi is that it can handle wireless networking more reliably than Nintendo Switch on its own. Bring the two devices together using a LAN adapter, and you’ve got a perfect pairing. Chris reports speeds up to three times faster using this hack.

A Nintendo Switch > LAN adaptor > Raspberry Pi

He ran a download speed test using a Nintendo Switch by itself, and then using a Nintendo Switch with a LAN adapter plugged into a Raspberry Pi. He found the Switch connected to the Raspberry Pi was quicker than the Switch on its own.

At 02mins 50secs of Chris’ video, he walks through the steps you’ll need to take to get similar results.

We’ve handily linked to some of the things Chris mentions here:

 

 

To test his creation, Chris ran a speed test downloading a 10GB game, Pokémon Shield, using three different connection solutions. The Raspberry Pi hack came out “way ahead” of the wireless connection relying on the Switch alone. Of course, plugging your Switch directly into your internet router would get the fastest results of all, but routers have a habit of being miles away from where you want to sit and play.

These loo rolls formed a choir

Post Syndicated from Ashley Whittaker original https://www.raspberrypi.org/blog/these-loo-rolls-formed-a-choir/

Have all of y’all been hoarding toilet roll over recent weeks in an inexplicable response to the global pandemic, or is that just a quirk here in the UK? Well, the most inventive use of the essential household item we’ve ever seen is this musical project by Max Björverud.

Ahh, the dulcet tones of wall-mounted toilet roll holders, hey? This looks like one of those magical ‘how do they do that?’ projects but, rest assured, it’s all explicable.

Max explains that Singing Toilet is made possible with a Raspberry Pi running Pure Data. The invention also comprises a HiFiBerry Amp, an Arduino Mega, eight hall effect sensors, and eight magnets. The toilet roll holders are controlled with the hall effect sensors, and the magnets connect to the Arduino Mega.

In this video, you can see the hall effect sensor and the 3D-printed attachment that holds the magnet:

Max measures the speed of each toilet roll with a hall effect sensor and magnet. The audio is played and sampled with a Pure Data patch. In the comments on his original Reddit post, he says this was all pretty straight-forward but that it took a while to print a holder for the magnets, because you need to be able to change the toilet rolls when the precious bathroom tissue runs out!

Max began prototyping his invention last summer and installed it at creative agency Snask in his hometown of Stockholm in December.

Resurrecting a vintage microwave sensor with Raspberry Pi

Post Syndicated from Ashley Whittaker original https://www.raspberrypi.org/blog/resurrecting-a-vintage-microwave-sensor-with-raspberry-pi/

Here’s one of those lovely “old tech new spec” projects, courtesy of hackster.io pro Martin Mander.

After finding a vintage Apollo microwave detector at a car boot sale, and realising the display hole in the top was roughly the same size as a small Adafruit screen, he saw the potential to breath new life into its tired exterior. And resurrected it as a thermal camera!

Right up top – the finished product!

Martin assumes it would have been used to test microwave levels in some kind of industrial setting, given microwave ovens were a rarity when it was produced.

Old components stripped and ready for a refit

Anyhow, a fair bit of the original case needed to be hacked at or sawn off to make sure all the new components could fit inside.  A Raspberry Pi Zero provides the brains of the piece. Martin chose this because he wanted to run the scipy python module to perform bicubic interpolation on the captured data, making the captured images look bigger and better. The thermal sensor is an Adafruit AMG8833IR Thermal Camera Breakout, which uses an 8×8 array of sensors to create the heat image.

The tiny but readable display screen

The results are displayed in real time on a bright 1.3″ TFT display. Power comes from a cylindrical USB battery pack concealed in the hand grip, which is recharged by opening up the nose cone and plugging in a USB lead. Just three Python scripts control the menu logic, sensor, and Adafruit.io integration, with the display handled by PyGame.

It gets better: with the click of a button, a snapshot of whatever the thermal camera is looking at is taken and then uploaded to an Adafruit dashboard for you to look at or share later.

Sensor and screen wired up

Martin’s original post is incredibly detailed, walking you through the teardown of the original piece, the wiring, how to tweak all the code and, of course, how he went about giving it that fabulous BB-8 orange-and-white makeover. He recorded the entire process in this 24-minute opus:

Apollo Pi Thermal Camera

This vintage Apollo microwave detector now has a shiny new purpose as a thermal camera, powered by a Raspberry Pi Zero with an Adafruit thermal camera sensor…

But what can you actually do with it? Martin’s suggestions range from checking your beer is cold enough before opening it, to testing your washing machine temperature mid-cycle. If you watch his video, you’ll see he’s also partial to monitoring cat tummy temperatures. His kid doesn’t like having his forehead Apollo Pi’d though.

Make a hamster feeder with Raspberry Pi Zero

Post Syndicated from Helen Lynn original https://www.raspberrypi.org/blog/make-a-hamster-feeder-with-raspberry-pi-zero/

People make marvellous things for their pets with Raspberry Pi. Here’s a splendid hamster feeder tutorial from Christopher Barnatt of Explaining Computers, just perfect if you’re after a small project for this weekend.

Raspberry Pi Zero Hamster Feeder

Raspberry Pi servo-controlled pet feeder, using a Raspberry Pi Zero and two SG90 servo motors. This project builds on the servo control code and setup from m…

All you need to build your hamster feeder is a Raspberry Pi Zero and peripherals, a couple of servos, some plasticard, sellotape and liquid polyadhesive, and some jumper wires. The video takes you very clearly through the entire set-up, from measurements to wiring details to Python code (which is available to download). As Christopher explains, this will allow you to feed your hamster controlled portions of food at suitable intervals, so that it doesn’t eat the lot in one go and, consequently, explode. What’s not to love?

Check out the Explaining Computers YouTube channel for more clear, detailed videos to help you do more with computing. And for more Raspberry Pi projects, head to our own Raspberry Pi projects, with hundreds of ideas for beginners and beyond available in English and many other languages.

Connect your Raspberry Pi 4 to an iPad Pro

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/connect-your-raspberry-pi-4-to-an-ipad-pro/

Have you ever considered attaching your Raspberry Pi 4 to an Apple iPad Pro? How would you do it, and why would you want to? Here’s YouTuber Tech Craft to explain why Raspberry Pi 4 is their favourite iPad Pro accessory, and why you may want to consider using yours in the same way.

We’ve set the video to start at Tech Craft’s explanation.

My Favourite iPad Pro Accessory: The Raspberry Pi 4

The Raspberry Pi 4 is my favourite accessory to use with the iPad Pro. In this video, learn more about what the Pi can do, what gear you need to get running with one, how to connect it to your iPad and what you’ll find it useful for.

 

Having installed Raspbian on Raspberry Pi and configured the computer to use USB-C as an Ethernet connection (read Ben Hardill’s guide to find out how to do this), Tech Craft could select it as an Ethernet device in the iPad’s Settings menu.

So why would you want to connect your Raspberry Pi 4 to your iPad? For starters, using your iPad instead of a conventional HDMI monitor will free up desk space, and also allow you to edit your code on the move. And when you’ve connected the two devices like this, you don’t need a separate power lead for Raspberry Pi, because the iPad powers the computer. So this setup is perfect for train or plane journeys, or for that moment when your robot stops working at a Raspberry Jam, or for maker conventions.

You can also use Raspberry Pi as a bridge between your iPad and portable hard drive, for disk management.

Tech Craft uses the SSH client Blink to easily connect to their Raspberry Pi via its fixed IP address, and with Juno Connect, they connect to a running Jupyter instance on their Raspberry Pi to do data science work.

For more information on using Raspberry Pi with an iPad, make sure you watch the whole video. And, because you’re a lovely person, be sure to subscribe to Tech Craft for more videos, such as this one on how to connect wirelessly to your Raspberry Pi from any computer or tablet:

Mobile Raspberry Pi with ANY iPad. No USB-C needed.

Following on my from earlier video about pairing the Raspberry Pi 4 with the iPad Pro over USB-C, this video show how to pair any iPad (or iPhone, or Android tablet) with a Pi4 or a Pi3 over WiFi.

How to control multiple servo motors with Raspberry Pi

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/how-to-control-multiple-servo-motors-with-raspberry-pi/

In the latest Explaining Computers video, Christopher Barnatt explains how to use servo motors with Raspberry Pi. Using servos is a great introduction to the digital making side of computing; servos allow you to control the movement of all manner of project components with your Raspberry Pi and a motor controller attached to its GPIO pins.

Raspberry Pi Servo Motor Control

Control of SG90 servos in Python on a Raspberry Pi, including an explanation of PWM and how a servo differs from a motor. You can download the code from the video at: https://www.explainingcomputers.com/pi_servos_video.html The five-pack of SG90 servos used in this video was purchased on Amazon.co.uk here: https://www.amazon.co.uk/dp/B07H9VC698/ref=nosim?tag=explainin-21 with a similar product on Amazon.com here: https://amzn.to/2QHshx3 (affiliate links).

Servos and your Raspberry Pi

Christopher picked up his SG90 servo motors online, where you’ll find a variety of servo options. What type of servo you need depends on the project you want to create, so be sure to consider the weight and size of what you plan to move, and the speed at which you need to move it.

As the motor controller connects via GPIO, you can even use the tiny £5 Raspberry Pi Zero to control your servo, which makes adding movement to your projects an option even when you’re under tight space constraints.

Brass freeform circuit (Raspberry Pi) Instagram tracker

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/brass-freeform-circuit-raspberry-pi-instagram-tracker/

A few of our favourite online makers decided to take part in a makers’ Secret Santa, producing home-made gifts based on their skills. So, OBVIOUSLY, Estefannie used a Raspberry Pi. Thanks, Estefannie.

HOW I HACKED INSTAGRAM FOR MY SECRET SANTA

I got in a Maker Secret Santa this year so I decided to make a thing and hack Instagram for it. #YTMakersSecretSanta MAKERS SECRET SANTA! FOLLOW EVERYONE: Kids Invent Stuff https://www.youtube.com/channel/UC-glo52BMvZH9PPUamjGIcw Colin Furze https://www.youtube.com/user/colinfurze The Hacksmithhttps://www.youtube.com/user/MstrJames Look Mum No Computer https://www.youtube.com/channel/UCafxR2HWJRmMfSdyZXvZMTw Sufficiently Advanced https://www.youtube.com/channel/UCVS89U86PwqzNkK2qYNbk5A Subscribe to my channel if you’d like to be the first to know when I publish the next video 🙂 Let me know what other videos you would like to see.

In the video above, Estefannie uses a Raspberry Pi to hack Instagram to illuminate a handmade freeform circuit whenever Kids Invent Stuff gains a like on a post.

“But why not use the Instagram API?”, I hear you cry. Well, as Estefannie explains, she wanted the gift to be a surprise, and if she had used the Instagram API, she would have had to have asked them for their details in order to access it.

Watch to the end of the video to see the gift that Estefannie received from her Secret Santa, a certain Colin Furze. You can see his complete build video for the Cat-o-Matic below.

How to run a script at start-up on a Raspberry Pi using crontab

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/how-to-run-a-script-at-start-up-on-a-raspberry-pi-using-crontab/

Do you need to run a script whenever your Raspberry Pi turns on? Here’s Estefannie to explain how to edit crontab to do exactly that.

How to start a script at start-up on a Raspberry Pi // LEARN SOMETHING

Do you want your Raspberry Pi to automatically run your code when it is connected to power? Then you are in the right place. In this new #LEARNSOMETHING video I show you how to make you Raspberry Pi run your script automatically when it is connected to a power source.

Running script on startup

While there are many ways of asking your Raspberry Pi to run a script on start-up, crontab -e is definitely one of the easiest.

AND, as Estefannie explains (in part thanks to me bugging asking her to do so), if you create a run folder on your desktop, you can switch out the Python scripts you want to run at start-up whenever you like and will never have to edit crontab again!

Weeeeee!

Now go write some wonderful and inspiring festive scripts while I take a well-earned nap. I just got off a plane yet here I am, writing blog posts for y’all because I love you THAT DARN MUCH!

This is Teddy. Teddy is also in the video.

Really, really awesome Raspberry Pi NeoPixel LED mirror

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/awesome-neopixel-led-mirror/

Check out Super Make Something’s awesome NeoPixel LED mirror: a 576 RGB LED display that converts images via the Raspberry Pi Camera Module and Raspberry Pi 3B+ into a pixelated light show.

Neopixel LED Mirror (Python, Raspberry Pi, Arduino, 3D Printing, Laser Cutting!) DIY How To

Time to pull out all the stops for the biggest Super Make Something project to date! Using 3D printing, laser cutting, a Raspberry Pi, computer vision, Python, and nearly 600 Neopixel LEDs, I build a low resolution LED mirror that displays your reflection on a massive 3 foot by 3 foot grid made from an array of 24 by 24 RGB LEDs!

Mechanical mirrors

If you’re into cool uses of tech, you may be aware of Daniel Rozin, the creative artist building mechanical mirrors out of wooden panels, trash, and…penguins, to name but a few of his wonderful builds.

Yup, this is a mechanical mirror made of toy penguins.

A digital mechanical mirror?

Inspired by Daniel Rozin’s work, Alex, the person behind Super Make Something, put an RGB LED spin on the concept, producing this stunning mirror that thoroughly impressed visitors at Cleveland Maker Faire last month.

“Inspired by Danny Rozin’s mechanical mirrors, this 3 foot by 3 foot mirror is powered by a Raspberry Pi, and uses Python and OpenCV computer vision libraries to process captured images in real time to light up 576 individual RGB LEDs!” Alex explains on Instagram. “Also onboard are nearly 600 3D-printed squares to diffuse the light from each NeoPixel, as well as 16 laser-cut panels to hold everything in place!”

The video above gives a brilliantly detailed explanation of how Alex made the, so we highly recommend giving it a watch if you’re feeling inspired to make your own.

Seriously, we really want to make one of these for Raspberry Pi Towers!

As always, be sure to subscribe to Super Make Something on YouTube and leave a comment on the video if, like us, you love the project. Most online makers are producing content such as this with very little return on their investment, so every like and subscriber really does make a difference.

Project anyone’s face onto your own with Raspberry Pi Zero

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/project-anyones-face-onto-your-own-with-raspberry-pi-zero/

Sean Hodgins is back with a new Halloween-themed project, this time using a pico projector and a Raspberry Pi Zero to display images and animations onto a mask.

It’s kinda creepy but very, very cool.

Face Changing Projection Mask – Be Anyone

Have a hard time deciding what to be on Halloween? Just be everything. Some links for the project below. Support my Free Open Source Projects by becoming joining the Patreon!

Face-changing projection mask

Sean designed his own PCB – classic Sean – to connect the header pins of a Raspberry Pi Zero to a pico projector. He used Photoshop to modify video and image files in order to correct the angle of projection onto the mask.

He then 3D-printed this low poly mask from Thingiverse, adapting the design to allow him to attach it to a welding mask headband he purchased online.

As Sean explains in the video, there are a lot of great ways you can use the mask. Our favourite suggestion is using a camera to take a photo of someone and project their own face back at them. This idea is reminiscent of the As We Are project in Columbus, Ohio, where visitors sit inside a 14-foot tall head as their face is displayed on screens covering the outside.
