Argon ONE: a super case for your Raspberry Pi

Post Syndicated from Helen Lynn original https://www.raspberrypi.org/blog/argon-one-raspberry-pi-case/

The friendly people at Argon40, one of our Approved Resellers in Hong Kong, have an already-successful Kickstarter on the go for their Argon ONE Raspberry Pi case. I’ve got one of them on my desk at the moment. It’s a very pleasing object. “That’s quite nice,” enthuses Gordon, who isn’t very good at enthusing.

The Argon ONE: look at the shiny!

The Argon ONE is a nifty little aluminium-alloy case that offers well thought-through cable, power, and temperature management. We chatted to Joseph from Argon40 about the team’s development process, and he explained:

When we started the project, we initially designed the product to suit our needs based on our experiences of playing around with the Raspberry Pi. We wanted a case that is nice to look and at the same time has all the basic features that we loved about the Raspberry Pi: small footprint, access to GPIO, low power consumption. Then we looked into the nice-to-have stuff like good heat dissipation for better performance, a proper shut-down, and a form factor that is elegant but not extravagant.

Clicky magnets

What I find particularly satisfying about the Argon ONE is its GPIO access. It has a neat recess with clear pin labels and access to an inbuilt, colour-coded header that connects to your Pi’s GPIO pins. When you’re not using the pins, you probably want to keep them away from dust, spilled coffee, and the gross candy-corn M&Ms that Alex sometimes throws at you for literally no reason. The Argon ONE helps you out here: a cover fits perfectly over the GPIO recess, held in place by magnets that are just exactly strong enough for the job. Being a fidgeter, I find that this lends itself to compulsive clicking.

Injection moulding

We like the build quality here, especially at this price point (it’s HK$157, US$20, or GB£15, and early-bird pledges are cheaper). The Argon40 team was keen to use alumnium for the upper part of the case, for robustness and durability along with good looks; that proved a challenge, given that they wanted to keep the case affordable. “Fortunately, we found a factory that allowed us to do aluminum-alloy injection instead of going for the CNC option,” says Joseph.

“Have you tried turning if off and on again?”

The Raspberry Pi doesn’t have a power button, and we hear a lot from people who’d like it to. Happily, our community has come up with lots of ways to add one: this case, for example. Once you install Argon40’s shutdown script in Raspbian, pressing the case’s power button will run the script to shut the Pi down cleanly, then cut the power.

Find out more on Kickstarter — this campaign is well worth a look if you’re after a decent case. Back to Joseph for the last word, with which we heartily agree:

At the end of the day, our goal is for people to have their Raspberry Pis on top of their work desks, study tables, and workstations and in their living rooms, instead of keeping their barebones Pi tucked inside a drawer. Because as the saying goes, “Out of sight, out of mind,” which means that if they don’t see their Raspberry Pi, they won’t be able to tinker around with it or play with it to create projects.

Watching VinylVideo with a Raspberry Pi A+

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/vinylvideo-with-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.

You wouldn’t download a car…

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/you-wouldnt-download-car-telsa-hack/

You wouldn’t download a car…but is that just because none of us know how to? And OF COURSE none of us know how to: it’s a really hard thing to do!

Raspberry Pi Tesla

Dramatic reenactment using a Mini because, c’mon, as if I can afford a Tesla!

Nikola Tesla was in love with a pigeon 😍🐦

True story. He was also the true father of the electrical age (sorry, not sorry, Edison) and looked so much like David Bowie that here’s David Bowie playing Nikola Tesla:

David Bowie as Nicola Tesla — Raspberry Pi Tesla

Not even pigeon love

Which is the perfect segue, as here’s a Tesla playing David Bowie, and here’s also where our story truly begins…

Some people dislike Tesla (the car manufacturer, not the scientist) but we love them

But some people also dislike going to the dentist, so ¯\_(ツ)_/¯. (I also love going to the dentist.)

I’m pretty sure the reason some people have issues with Tesla is that electric cars still seem like a form of magic we’re not quite comfortable with.

Whatever people’s reason for holding a grudge against Tesla, recent findings at a university in Belgium this week have left the tech community aflutter: the academics announced that, with the aid of a “$35 computer”, they can clone your Tesla car key and steal. Your. Car.

If you haven’t guessed yet, we’re the ones behind the $35 computer. (Hi!)

Says WIRED: A team of researchers at the KU Leuven University in Belgium on Monday plan to present a paper at the Cryptographic Hardware and Embedded Systems conference in Amsterdam, revealing a technique for defeating the encryption used in the wireless key fobs of Tesla’s Model S luxury sedans. With about $600 in radio and computing equipment, they can wirelessly read signals from a nearby Tesla owner’s fob. Less than two seconds of computation yields the fob’s cryptographic key, allowing them to steal the associated car without a trace.

When I said that the tech community was all aflutter, what I meant was, on the whole, we find this hack somewhat entertaining but aren’t all that shocked by it. Not because we hate Tesla, but because these things happen. Technology is ever evolving, and that $600 worth of kit can do a thing to another thing isn’t all that unbelievable.

Sweet Cyber Jones on Twitter

The keys to my new Tesla https://t.co/jNViEZBxrB

The academics showed an example of the hack using “just” a couple of radios, a Raspberry Pi, some batteries, and your basic, off-the-shelf “pre-computed table of keys on a portable hard drive”. And through the magic of electric car IoT technology, Tesla instantly released a series of fixes to allow existing Tesla users to protect their cars against the attack, which is all kinds of cool.

Alex, why are you making such light of this?!

Because The Fast and the Furious isn’t real. And I highly doubt there’s a criminal enterprise out there that’s capable of building the same technology as well-funded university researchers.

Yes, this study from KU Leuven University is interesting. And yes, we all had a good laugh at the expense of Tesla and Elon Musk, but we don’t need academics to provide material for that. And I genuinely love Tesla and the work Elon is doing. True love.

Instead, we should be seeing this as a reminder that data encryption and online security are things we all need to take seriously in this digital world. So stop connecting your phone to whatever free WiFi network you can find, stop using PASSWORD123 for all your online accounts, and spend a little more time learning how you can better protect yourself and your family from nasty people on the internet.

And leave Britney Tesla alone!

Cabin Cloud: bump-free travel on the night bus

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/cabin-cloud-bump-free-travel-night-bus/

Planes, trains, and automobiles — we all have our preference. And at one company in California, the team is trying to smooth bus travel to broaden commuters’ options for a blissful night’s sleep.

Cabin bus Raspberry Pi Wired

Leaving on a jet plane

Not everyone wants to fly. While many enjoy the feel of take-off and landing and the high speed at which they can travel from A to B, others see planes as worrisome tin cans of doom, suspended in the air by unreliable magic. I consider myself mostly the former, with a hint of the latter for balance.

In truth, I’d rather catch a train, where the smooth ride sends me into blissful sleep, only occasionally interrupted by a snap of “Damn, did I miss my stop?!”.

But trains are limited to where their tracks lead, which is why so many people still opt to travel by bus. But who can sleep on a bus when the roads are dotted with potholes and cracks? I can’t, and neither can many of the 10000 passengers of the Cabin bus, an overnight service running between Los Angeles and San Francisco.

Cabin bus travel

To address complaints about the road conditions affecting costumers’ sleep, the Cabin team decided to challenge gravity using a Raspberry Pi and the electric motor from a hoverboard in their new venture Cabin Cloud.

Introducing the first active suspension system designed specifically with passenger sleep in mind. Combining patent-pending software and hardware, our technology mutes ‘road turbulence’ and dramatically reduces vibration, so you can get a good night’s sleep while on a moving vehicle.

“We can isolate a passenger’s body, and input frequencies that help people relax and fall asleep,” explains Cabin CTO Tom Currier. “We have a set of sensors that are measuring the acceleration of the vehicle, and also the bed, to compute in real time what we should be cancelling out.”

Cabin bus Raspberry Pi Wired

The sensors are accelerometers, two per bed, that measure the bumps from the road and adjust the bed accordingly — up to 1000 times a second. The Cabin Cloud beds only adjust for motion up and down: the team isn’t too concerned about back-and-forth movements due to breaking too hard or turning corners, since Cabin busses predominantly travel on wide, open highways.

Delve a little deeper

Check out this article from Wired for more about the project, and about how similar tech is implemented in trucks for long-haul drivers, and in aeroplanes for turbulence-free travel. You can also sign up for the Cabin Cloud newsletter here.

But the big question about Cabin Cloud is…

Does it have Bluetooth?

Build a Raspberry Pi pocket projector…how awesome is that?!

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/build-raspberry-pi-pocket-projector/

YouTuber MickMake has been working hard on producing a Raspberry Pi pocket projector with the Raspberry Pi Zero W. We’re excited. We know you’re excited. So enough of us talking, here’s Mick with more!

#210 Build a Pi Zero W pocket projector! // Project

2 for 10 PCBs (48 hour quick turn around): https://jlcpcb.com/?ref=mickmake Make a pocket projector based on the DLP2000EVM and Raspberry Pi Zero W! Nice!

Sharing is caring

YouTuber Novaspirit Tech released a new video yesterday, reviewing MickMake’s Raspberry Pi Zero W pocket projector, and the longer the video ran on, the more we found ourselves wanting our own!

Thank you, Novaspirit Tech, for reminding us to subscribe to MickMake. And thank you, MickMake, for this awesome project!

The Pi Zero W pocket projector of your dreams

In his project video, Mick goes into great detail about the tech required for the project, along with information on the PCB he’s created to make it simpler and easier for other makers to build their own version.

raspberry pi pocket pi projector mickmakes

The overall build consists of the $10 Raspberry Pi Zero W, a DLP2000 board, and MickMake’s homemade $4 PCB, which allows you to press-fit the projector together into a very tidy unit with the same footprint as a Raspberry Pi 3B+ — perfectly pocket-sized.

Specs and things

While the projected images obviously aren’t as clear as those of high-end projectors, MickMake’s projector is definitely good enough to replace a cheap desktop display, or to help you show off your projects on the go at events such as Raspberry JamsCoolest Projects, and Maker Faire. And due to its low power consumption, the entire unit can run off the kind of rechargeable battery pack you may already be carrying around for your mobile phone. Nice!

In his review video, NovaSpirit Tech goes through more of the projector’s playback and spec details, and also does a series of clarity tests in various lights. So why read about it when you can watch it? Here you go:

PiPod: the Raspberry Pi Zero portable music player

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/pipod-pi-zero-music-player/

We’ve seen many Raspberry Pi-powered music players over the years. But rarely are they as portable (and snazzy) as the PiPod by Hackaday user Bram.

PiPod Raspberry Pi music player

Portable music

My biggest regret in life? Convinced I wouldn’t need my 160GB iPod Classic anymore thanks to Spotify, I sold it to CEX for a painfully low price. But not only was I mistaken as to how handy it would have been to hold on to, the money I made doesn’t seem to justify parting ways with such an iconic piece of technology no longer available to purchase anew.

Which is why the PiPod project from Netherlands-based Hackaday user ‘Bram’ caught my attention instantly.

The PiPod

I made this music player because I wasn’t satisfied with the current playback methods that are available. The music streaming services available started to feel like radio stations with the same music repeating, they are also depended on an online internet connection while there might be offline functionality it is still limited by the available storage on your phone.

We hear ya, Bram.

With his mind set on creating a music player of their own to overcome the limitations on offer without having to pay hundreds of Euros for high-end portable devices, Bram got to work.

The PiPod, now in its third iteration, offers users a range of functionality and can be made fairly cheaply using Bram’s custom PCB.

PiPod Raspberry Pi music player

For the display, Bram uses a 2.2″ TFT screen connected to a Raspberry Pi Zero. As can be seen above, the screen offers all the information you could ever require of your media player despite the low 320 by 240 resolution.

For music playback, the PCB also includes the PCM5102A a 24-bit I2S DAC that offers a high-quality audio output accessible via a 3.5mm jack. And for power, Bram has done his homework, incorporating a series of components to protect the device from overcurrent, thermal overload and various other power-related concerns.

PiPod Raspberry Pi music player

The music interface itself uses VLC for backend playback and PyGame at the frontend, and all information and code for the project can be found on the Hackaday project page, including the 3D-printable files for the rather snazzy casing and its fantastic dock.

PiPod Raspberry Pi music player

Such snazziness

We’re sure Bram’s PiPod isn’t the only portable music device with a Pi inside. What have we missed? Share yours with us in the comments or on social media so we may bathe in their glory and give them the attention they deserve.

Astronaut-made virtual co-pilot

Post Syndicated from Liz Upton original https://www.raspberrypi.org/blog/virtual-co-pilot-solar-pilot-guard/

This project features several of our favourite things. Astronauts! Machine learning! High-altitude danger! Graphs! (It could only get slightly better with the addition of tap-dancing centaurs.) Read on to have your nerdliest pleasure centres tickled.

Solar Pilot Guard - wing of a plane in flight

Your interest should be focussed on the strange fin with the red tip. Although we agree the mountains look nice too.

Solar Pilot Guard, a Foale family project

Michael Foale is a former astronaut with dual British/American citizenship; and thanks to that dual citizenship was revered by British kids like me as some kind of Superman when he spent time on the Russian Mir space station back in the 1990s. It’s always great to see one of our heroes using the Raspberry Pi, but it’s doubly great when the use it’s being put to is so very, very cool.

Foale’s daughter Jenna is a PhD candidate in computational fluid dynamics, and together they have engineered a machine-learning system called Solar Pilot Guard to help prevent aircraft crashes, using the Wolfram Language on a Raspberry Pi. A solar-powered probe (that fin in the image above) detects changes in acceleration and air pressure to spot potential loss-of-control (LOC) events in flight, calculating the probability of each pressure/acceleration event representing a possible LOC event.

Solar Pilot Guard schematic cross-section

Click to embiggen

If it detects a possible LOC event, the system issues a voice command to the pilot over Bluetooth speakers, using machine learning to tell the pilot what corrective measures they should take.

Here it is in action:

Solar Pilot Guard use in-flight

An example of in-flight operation of the Solar Pilot Guard (SPG), issuing commands for correction of flight behavior that could lead to loss of control (LOC). Demonstrated commands: Push, Power – Left, Left – Right, Right Submitted to EAA AirVenture, Oshkosh 2017.

Losing control to generate training data

In order to train the network, Michael Foale had to feed the machine data about what LOCs and normal flight look like — which meant flying the kit in ways which would make the plane lose control, not just once, but over and over, until the neural net had the data it needed to differentiate different sorts of LOC events. Told you he was a superhero.

A stack of different machine learning functions at different levels of abstraction are working together here. This is a training set from one of the (presumably terrifying) training flights:

Solar Pilot Guard training set

The Pi processes and learns from this data; if you’re interested in a very deep dive into the way this all works, and how you can build your own neural networks using the Wolfram Language, there’s a very comprehensive treatment over at the Wolfram blog.

We love seeing projects like this that recognise just how robust and powerful a little Raspberry Pi can be. Jenna and Michael: thank you for sharing what you’ve been working on here. It’s one of the coolest and most audacious projects we’ve seen in a long time.

The affordable Raspberry Pi night vision goggles of your dreams

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/raspberry-pi-zero-night-vision-goggles/

I just searched online for night vision goggles, and the prices seem to vary between £600 and £27000. That’s a little bit higher than my budget of ‘as cheap as humanly possible’, but lucky for me (and you!), Redditor Mtnbikerdunn has created a set of Raspberry Pi Zero–powered night vision goggles that come in at around $100. Nice. Finally my Silence of the Lambs cosplay is complete!

“They came to be in a dream.” begins Redditor mtnbikerdunn in his r/raspberrry_pi post. “I woke up to my idea whiteboard full of notes and diagrams drawn by a half-asleep version of myself”

night vision goggles raspberry pi zero

A view through the night vision goggles

A Raspberry Pi Zero and…

mtnbikerdunn goes on to explain how the few pieces of tech required to build the goggles came in at less than $100/£78. The results are impressive!

It’s basically a first-person viewdrone headset with a Raspberry Pi Zero mounted within, some infrared LED lights, an infrared camera, and a few 18650 Lithium-ion batteries to power it all. Charges with a standard micro USB cable and doesn’t require anything to get it running except an on/off switch.

The headset in this project is the Yuneec SkyView FPV HDMI, used by drone pilots to gain a first-person view while flying. And since the headset has HDMI connectivity, mtnbikerdunn was able to hook it up directly to the Pi Zero. The camera is a third-party Raspberry Pi fisheye camera, while the rest of the tech consists of the standard gubbins any maker should have lying around, such as a micro SD card, a $5 Raspberry Pi Zero, and a button.

The power pack contains two 18650 Lithium-ion batteries, providing the goggles with roughly three hours of runtime. To make the charge last longer, mtnbikerdunn stripped down Raspbian Stretch Lite, removing any unnecessary programs that could run in the background and eat up juice.

Dream big

All that’s left is for me to sit and hope that mtnbikerdunn has a dream about how to make a working TARDIS using a Pi Zero, and then I’ll be the talk of the town at next year’s London Film and Comic Con!

A list of Raspberry Pi books for #BookLoversDay

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

While yesterday’s blog post covered YouTubers who create video tutorials about using the Raspberry Pi, today we want to focus on a more traditional medium in honour of #BookLoversDay.

Raspberry Pi books

Since we launched the Raspberry Pi back in 2012, staff and community members alike have been writing guides and projects books about our little green board, with some releasing them as free PDFs and others donating a portions of the revenue to the Raspberry Pi Foundation.

Here are a few of our favourite books, written by our colleagues and you, our glorious community.

Getting started

For beginners just entering the world of Raspberry Pi, there is no end of ‘Getting started’ resources available online. For those of you who want a physical reference work, or who plan on giving a Raspberry Pi as a gift, here are some of the best beginners’ guides available:

Raspberry Pi for Dummies - Raspberry Pi booksAlmost all of us will have at least one for Dummies book lying around at home. Easy to read and full of information, the series is a go-to for many. The third edition of the Raspberry Pi for Dummies book came out in late 2017, and you can read the first two chapters on co-author Sean McManus’s website.

The Raspberry Pi User GuideRaspberry Pi User Guide - Raspberry Pi books was co-written by Eben Upton, creator of the Raspberry Pi and co-founder of the Raspberry Pi Foundation. So it’s fair to say that the information in this guide comes directly from the horse’s mouth…so to speak. You can read an excerpt of the book on the publisher’s website.

Adventures in Raspberry Pi - Raspberry Pi booksFor younger users, Carrie Anne Philbin’s Adventures in Raspberry Pi is both an introduction guide and project book, taking young beginners from the basics of setting up and using their Raspberry Pi through to trying out coding and digital making projects.

Sync modular synths and electronic instruments with a DIY kit

Post Syndicated from Oliver Quinlan original https://www.raspberrypi.org/blog/eurorack-modular-synth-spink0/

The Raspberry Pi community is wonderfully collaborative, with people all over the world supporting each other to make things they care about. It’s part of a much wider maker movement, and a new project from seismic industries, called spink0, brings the power of Raspberry Pi to another DIY community in the music world: modular synthesizer enthusiasts.

spink0 Raspberry Pi Zero W eurorack modular synth

Modular synths

Modular synthesizers are dedicated machines for creating and controlling electrically generated sounds. Unlike the ubiquitous electronic keyboards, they don’t offer pre-set sounds. Instead, they allow players to deeply manipulate the nature of sounds: by connecting different modules with each other via cables, players use signals from one module to affect and alter the sounds from another, and generally get very creative with not just the musical notes but the sound itself.

MOTM modular - Synth patch for second commission (by Charles Hutchins)

A low to middling number of cables

Modular synths have seen a huge growth in popularity in the last few years. This year’s BBC Proms even featured an improvised modular synthesizer performance in the Royal Albert Hall.

Recent developments in technology, and enterprising module creators, have made these machines much more accessible, largely through a modular synth format called eurorack. A thriving DIY community has also grown, with people assembling their own modular synths using kits or even building their own modules from scratch.

Enter the Raspberry Pi Zero W, just the right size for adding sophisticated computing power to a eurorack module. The spink0 eurorack module uses the power of a Zero W to allow musicians to keep their eurorack synth music in time with music created with more common electronic instruments like drum machines and computers. The Zero W connects to a wireless network and uses the Ableton Link protocol to share timing information across this network. It converts this digital data into the analogue square wave clock pulses that modular synths use for musical timing.

With spink0, seismic industries have developed shaduzLABS’ original prototype pink-0 into an open-source DIY kit including PCBs and a panel that rather neatly integrate a Pi Zero into a eurorack module (a CLK/RST generator, to be exact).

Pi-powered electronic music jam sessions

This opens up a whole world of jamming potential to musicians who use these esoteric machines to make their sounds. A group of electronic musicians can get together, connect over a wireless network, and improvise ideas, all kept in time across the network. Thanks to spink0, eurorack synths can coexist with computers and even iPads and other tablets.

Now anyone can link their modular synth with other music machines and computers for collaborative jams! Seismic industries offer the DIY kit, plus full instructions and code, so you can solder yours at home, or you can buy spink0 preassembled if you wish.

Block ads at home using Pi-hole and a Raspberry Pi

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

Today’s blog post comes from Jacob Salmela, creator of Pi-hole, a network-wide ad blocker used by Raspberry Pi enthusiasts to block advertisements on all devices connected to their home network.

What is Pi hole?

An explainer video about the network-wide ad blocker and how to install it.

What is Pi-hole?

Pi-hole is a network-wide ad blocker. Instead of installing adblockers on every device and every browser, you can install Pi-hole once on your network, and it will protect all of your devices. Because it works differently than a browser-based ad-blocker, Pi-hole also block ads in non-traditional places, such as in games and on smart TVs.

I originally made Pi-hole as a replacement for the AdTrap device. I have a background in networking, so I figured I could make something better with some inexpensive hardware like the Raspberry Pi. I spent two summers working on the project and made the code open source. Four years later, we have several developers working on Pi-hole, and we have grown into a very large project with a vibrant community.

How does it work?

Pi-hole functions as an internal, private DNS server for your network. For many home users, this service is already running on your router, but your router doesn’t know where advertisements are — but Pi-hole does. Pi-hole will intercept any queries for known ad-serving domains and deny them access, so ads won’t be downloaded.

Using Pi-hole on a Raspberry Pi

Users configure their router’s DHCP options to force clients to use Pi-hole as their DNS server.

This means websites will load normally but without advertisements; since ads are never downloaded, sites will load faster. Pi-hole also caches these queries, so responsiveness to commonly visited websites can also be noticed.

Pi-hole and Raspberry Pi

The Pi-hole software has very low resource requirements and can even run on a Raspberry Pi Zero W. And despite its name, you can also install Pi-hole on several other Linux distributions. Many users install it on a VM or in a container and let it provide services that way. But since Pi-hole’s resource requirements are so low, many users have found it to be a good use of their older, lower-powered model Raspberry Pis. Simply install Pi-hole, connect the Pi to your router, and begin blocking ads everywhere.

Using Pi-hole on a Raspberry Pi

The Pi-hole web interface allows users to monitor ad-blocking data, to access the query log, and more.

You can also pair Pi-hole with a VPN to get ad blocking via a cellular connection. This will help you with bandwidth limits and data costs, because your phone won’t need to download advertising videos and images.

Install Pi-hole

Pi-hole can be downloaded to your Raspberry Pi via a one-step automated install — just open a terminal window and run the following command:

curl -sSL https://install.pi-hole.net | bash

You can find more information about setting up Pi-hole on your Raspberry Pi on the Pi-hole GitHub repository here.

If you need support with using Pi-hole or want to chat with the Pi-hole community, you can visit their forum here.

If you’d like to support Jacob and the Pi-hole team as they continue to develop the functions of their ad-blocker, you can sign up as a Patreon, donate directly, or purchase swag, including the Pi-hole case from Pi Supply.

Dialling into local stories with Jura whisky phones

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

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

Raspberry Pi Bright Signal Jura whisky

Jura whisky from Jura

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

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

Building phones for Jura

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

Retrofitting phoneboxes

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

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

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

Raspberry Pi Bright Signal Jura whisky

Motion sensor–triggered phone calls

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

Raspberry Pi Bright Signal Jura whisky

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

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

How to build a competiton-ready Raspberry Pi robot

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

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

bbc robot wars raspberry pi robot

Robotics 101

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

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



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

Prepare your buggy for battle

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

raspberry pi robot

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

Pi Wars

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

Tanya Fish on Twitter

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

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

raspberry pi robot

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

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

And now for the chainsaws!

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

Using E Ink displays with a Raspberry Pi

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

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

Raspberry Pi E Ink Displays

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

E Ink displays

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

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

</e_ink_101_with_alex>

E Ink displays for your Raspberry Pi projects

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

Repurposing old e-readers

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

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

DIY: Build A Better Bike Computer

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

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

Brand-new E Ink displays

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

Raspberry Pi E Ink Displays

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

Raspberry Pi E Ink Displays

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

Brian Corteil 🤖 on Twitter

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

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

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

Raspberry Pi E Ink Monzo Display

Past predictions of Liz Upton

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

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

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

Naturebytes’ weatherproof Pi and camera case

Post Syndicated from Helen Lynn original https://www.raspberrypi.org/blog/naturebytes-weatherproof-pi-and-camera-case/

Naturebytes are making their weatherproof Wildlife Cam Case available as a standalone product for the first time, a welcome addition to the Raspberry Pi ecosystem that should take some of the hassle out of your outdoor builds.

A robin on a bird feeder in a garden with a Naturebytes Wildlife Cam mounted beside it

Weatherproofing digital making projects

People often use Raspberry Pis and Camera Modules for outdoor projects, but weatherproofing your set-up can be tricky. You need to keep water — and tiny creatures — out, but you might well need access for wires and cables, whether for power or sensors; if you’re using a camera, it’ll need something clear and cleanable in front of the lens. You can use sealant, but if you need to adjust anything that you’ve applied it to, you’ll have to remove it and redo it. While we’ve seen a few reasonable options available to buy, the choice has never been what you’d call extensive.

The Naturebytes case

For all these reasons, I was pleased to learn that Naturebytes, the wildlife camera people, are releasing their Wildlife Cam Case as a standalone product for the first time.

Naturebytes case open

The Wildlife Cam Case is ideal for nature camera projects, of course, but it’ll also be useful for anyone who wants to take their Pi outdoors. It has weatherproof lenses that are transparent to visible and IR light, for all your nature observation projects. Its opening is hinged to allow easy access to your hardware, and the case has waterproof access for cables. Inside, there’s a mount for fixing any model of Raspberry Pi and camera, as well as many other components. On top of all that, the case comes with a sturdy nylon strap to make it easy to attach it to a post or a tree.

Naturebytes case additional components

Order yours now!

At the moment, Naturebytes are producing a limited run of the cases. The first batch of 50 are due to be dispatched next week to arrive just in time for the Bank Holiday weekend in the UK, so get them while they’re hot. It’s the perfect thing for recording a timelapse of exactly how quickly the slugs obliterate your vegetable seedlings, and of lots more heartening things that must surely happen in gardens other than mine.

Brutus 2: the gaming PC case of your dreams

Post Syndicated from Janina Ander original https://www.raspberrypi.org/blog/brutus-2-gaming-pc-case/

Attention, case modders: take a look at the Brutus 2, an extremely snazzy computer case with a partly transparent, animated side panel that’s powered by a Pi. Daniel Otto and Carsten Lehman have a current crowdfunder for the case; their video is in German, but the looks of the build speak for themselves. There are some truly gorgeous effects here.

What’s case modding?

Case modding just means modifying your computer or gaming console’s case, and it’s very popular in the gaming community. Some mods are functional, while others improve the way the case looks. Lots of dedicated gamers don’t only want a powerful computer, they also want it to look amazing — at home, or at LAN parties and games tournaments.

The Brutus 2 case

The Brutus 2 case is made by Daniel and Carsten’s startup, 3nb electronics, and it’s a product that is officially Powered by Raspberry Pi. Its standout feature is the semi-transparent TFT screen, which lets you play any video clip you choose while keeping your gaming hardware on display. It looks incredibly cool. All the graphics for the case’s screen are handled by a Raspberry Pi, so it doesn’t use any of your main PC’s GPU power and your gaming won’t suffer.

The software

To use Brutus 2, you just need to run a small desktop application on your PC to choose what you want to display on the case. A number of neat animations are included, and you can upload your own if you want.

So far, the app only runs on Windows, but 3nb electronics are planning to make the code open-source, so you can modify it for other operating systems, or to display other file types. This is true to the spirit of the case modding and Raspberry Pi communities, who love adapting, retrofitting, and overhauling projects and code to fit their needs.

Brutus 2 PC case powered by Raspberry Pi

Daniel and Carsten say that one of their campaign’s stretch goals is to implement more functionality in the Brutus 2 app. So in the future, the case could also show things like CPU temperature, gaming stats, and in-game messages. Of course, there’s nothing stopping you from integrating features like that yourself.

If you have any questions about the case, you can post them directly to Daniel and Carsten here.

The crowdfunding campaign

The Brutus 2 campaign on Startnext is currently halfway to its first funding goal of €10000, with over three weeks to go until it closes. If you’re quick, you still be may be able to snatch one of the early-bird offers. And if your whole guild NEEDS this, that’s OK — there are discounts for bulk orders.

Invent new sounds with Google’s NSynth Super

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

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

Google Open NSynth Super Testing

Uploaded by AB Open on 2018-04-17.

What is the NSynth Super?

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

Google Nsynth Super Raspberry Pi

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

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

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

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

Build your own NSynth Super

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

Google Nsynth Super Raspberry Pi

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

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

Music and Raspberry Pi

The Raspberry Pi has been widely used for music production and music builds. Be it retrofitting a boombox, distributing music atop Table Mountain, or coding tracks with Sonic Pi, the Pi offers endless opportunities for musicians and music lovers to expand their repertoire of builds and instruments.

If you’d like to try more music-based projects using the Raspberry Pi, you can check out our free resources. And if you’ve used a Raspberry Pi in your own musical project, please share it with us in the comments or via our social network accounts.

AIY Projects 2: Google’s AIY Projects Kits get an upgrade

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/google-aiy-projects-2/

After the outstanding success of their AIY Projects Voice and Vision Kits, Google has announced the release of upgraded kits, complete with Raspberry Pi Zero WH, Camera Module, and preloaded SD card.

Google AIY Projects Vision Kit 2 Raspberry Pi

Google’s AIY Projects Kits

Google launched the AIY Projects Voice Kit last year, first as a cover gift with The MagPi magazine and later as a standalone product.

Makers needed to provide their own Raspberry Pi for the original kit. The new kits include everything you need, from Pi to SD card.

Within a DIY cardboard box, makers were able to assemble their own voice-activated AI assistant akin to the Amazon Alexa, Apple’s Siri, and Google’s own Google Home Assistant. The Voice Kit was an instant hit that spurred no end of maker videos and tutorials, including our own free tutorial for controlling a robot using voice commands.

Later in the year, the team followed up the success of the Voice Kit with the AIY Projects Vision Kit — the same cardboard box hosting a camera perfect for some pretty nifty image recognition projects.

For more on the AIY Voice Kit, here’s our release video hosted by the rather delightful Rob Zwetsloot.

AIY Projects adds natural human interaction to your Raspberry Pi

Grab yourself a copy in stores or online now: http://magpi.cc/2pI6IiQ This first AIY Projects kit taps into the Google Assistant SDK and Cloud Speech API using the AIY Projects Voice HAT (Hardware Accessory on Top) board, stereo microphone, and speaker (included free with the magazine).

AIY Projects 2

So what’s new with version 2 of the AIY Projects Voice Kit? The kit now includes the recently released Raspberry Pi Zero WH, our Zero W with added pre-soldered header pins for instant digital making accessibility. Purchasers of the kits will also get a micro SD card with preloaded OS to help them get started without having to set the card up themselves.

Google is also hard at work producing AIY Projects companion apps for Android, iOS, and Chrome. The Android app is available now to coincide with the launch of the upgraded kits, with the other two due for release soon. The app supports wireless setup of the AIY Kit, though avid coders will still be able to hack theirs to better suit their projects.

Google has also updated the AIY Projects website with an AIY Models section highlighting a range of neural network projects for the kits.

Get your kit

The updated Voice and Vision Kits were announced last night, and in the US they are available now from Target. UK-based makers should be able to get their hands on them this summer — keep an eye on our social channels for updates and links.
