Raspberry Pi interactive wind chimes

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/interactive-wind-chimes/

Grab yourself a Raspberry Pi, a Makey Makey, and some copper pipes: it’s interactive wind chime time!

Perpetual Chimes

Perpetual Chimes is a set of augmented wind chimes that offer an escapist experience where your collaboration composes the soundscape. Since there is no wind indoors, the chimes require audience interaction to gently tap or waft them and encourage/nurture the hidden sounds within – triggering sounds as the chimes strike one another.

Normal wind chimes pale in comparison

I don’t like wind chimes. There, I said it. I also don’t like the ticking of the second hand of analogue clocks, and I think these two dislikes might be related. There’s probably a name for this type of dislike, but I’ll leave the Googling to you.

Sound designer Frazer Merrick’s interactive wind chimes may actually be the only wind chimes I can stand. And this is due, I believe, to the wonderful sounds they create when they touch, much more wonderful than regular wind chime sounds. And, obviously, because these wind chimes incorporate a Raspberry Pi 3.

Since there is no wind indoors, the chimes require audience interaction to gently tap or waft them and encourage/nurture the hidden sounds within — triggering sounds as the chimes strike one another. Since the chimes make little acoustic noise, essentially they’re broken until you collaborate with them.

Bringing a book to life with Raspberry Pi | Hello World #9

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/bringing-a-book-to-life-with-raspberry-pi-hello-world-9/

Sian Wheatcroft created an interactive story display to enable children to explore her picture book This Bear, That Bear. She explains the project, and her current work in teaching, in the newest issue of Hello World magazine, available now.

The task of promoting my first children’s picture book, This Bear, That Bear, was a daunting one. At the time, I wasn’t a teacher and the thought of standing in front of assembly halls and classrooms sounded terrifying. As well as reading the book to the children, I wanted to make my events interactive using physical computing, showing a creative side to coding and enabling a story to come to life in a different way than what the children would typically see, i.e. animated retellings.

The plan

Coming from a tech-loving family, I naturally gravitated towards the Raspberry Pi, and found out about Bare Conductive and their PiCap. I first envisaged using their conductive paint on the canvas, enabling users to touch the paint to interact with the piece. It would be some sort of scene from the book, bringing some of the characters to life. I soon scrapped that idea, as I discovered that simply using copper tape on the back of the canvas was conductive enough, which also allowed me to add colour to the piece.

I enlisted the help of my two sons (two and five at the time) — they gladly supplied their voices to some of the bears and, my personal favourite on the canvas, the ghost. The final design features characters from the book — when children touch certain areas of the canvas, they hear the voices of the characters.

The back of the canvas, covered in copper tape

Getting the project up and running went pretty smoothly. I do regret making the piece so large, though, as it proved difficult to transport across the country, especially on the busy London Underground!

Interactivity and props

The project added a whole other layer to the events I was taking part in. In schools, I would read the book and have props for the children to wear, allowing them to act out the book as I read aloud. The canvas then added further interaction, and it surprised me how excited the children were about it. They were also really curious and wanted to know how it worked. I enjoyed showing them the back of the canvas with all its copper tape and crocodile clips. They were amazed by the fact it was all run on the Raspberry Pi — such a tiny computer!

The front of the interactive canvas

Fast-forward a few years, and I now find myself in the classroom full-time as a newly qualified teacher. The canvas has recently moved out of the classroom cupboard into my newly developed makerspace, in the hope of a future project being born.

I teach in Year 3, so coding in Python or using the command line on Raspbian may be a little beyond my students. However, I have a keen interest in project-based learning and am hoping to incorporate a host of cross-curricular activities with my students involving the canvas.

I hope to instil a love for digital making in my students and, in turn, show senior leaders what can be done with such equipment and projects.

A literacy project

This work really lends itself to a literacy project that other educators could try. Perhaps you’re reading a picture book or a more text-based piece: why not get the students to design the canvas using characters from the story? The project would also work equally well with foundation subjects like History or Science. Children could gather information onto the canvas, explaining how something works or how something happened. The age of the children would influence the level of involvement they had in the rest of the project’s creation. The back end could be pre-made — older children could help with the copper tape and wiring, while younger children could stop at the design process.

Part of the project is getting the children to create sounds to go with their design, enabling deeper thinking about a story or topic.

It’s about a collaborative process with the teacher and students, followed by the sharing of their creation with the broader school community.

Quick Fix — a vending machine for likes and followers

Post Syndicated from Liz Upton original https://www.raspberrypi.org/blog/quick-fix-a-vending-machine-for-likes-and-followers/

Sometimes we come across a project that just scores a perfect 10 on all fronts. This is one of them: an art installation using Raspberry Pi that has something interesting to say, does it elegantly, and is implemented beautifully (nothing presses our buttons like a make that’s got a professionally glossy finish like this).

Quick Fix is a vending machine (and art installation) that sells social media likes and followers. Drop in a coin, enter your social media account name, and an army of fake accounts will like or follow you. I’ll leave the social commentary to you. Here’s a video from the maker, Dries Depoorter:

Quick Fix – the vending machine selling likes and followers

Quick Fix in an interactive installation by Dries Depoorter. The artwork makes it possible to buy followers or likes in just a few seconds. For a few euros you already have 200 of likes on Instagram. “Quick Fix “is easy to use. Choose your product, pay and fill in your social media username.

There’s a Raspberry Pi 3B+ in there, along with an Arduino, powering a coin acceptor and some I2C LCD screens. Then there’s a stainless steel heavy-duty keyboard, which we’re lusting after (a spot of Googling unearthed this, which appears to be the same thing, if you’re in the market for a panel-mounted beast of a keyboard).

This piece was commissioned by Pixelache, a cultural association from Helsinki, whose work looks absolutely fascinating if you’ve got a few minutes to browse. Thanks to them and to Dries Depoorter — I have a feeling this won’t be the last of his projects we’re going to feature here.

Make art with LEDs | HackSpace magazine #16

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/make-art-with-leds-hackspace-16/

LEDs are awesome

Basically, LEDs are components that convert electrical power into light. Connect them to a power source (with some form of current limiter) in the right orientation, and they’ll glow.

Each LED has a single colour. Fortunately, manufacturers can pack three LEDs (red, green, and blue) into a single component, and varying the power to each LED-within-an-LED produces a wide range of hues. However, by itself, this type of colourful LED is a little tricky to control: each requires three inputs, so a simple 10×10 matrix would require 300 inputs. But there’s a particular trick electronics manufacturers have that make RGB LEDs easy to use: making the LEDs addressable!

An RGB LED

Look: you can clearly see the red, green, and blue elements of this RGB LED

Addressable LEDs

Addressable LEDs have microcontrollers built into them. These aren’t powerful, programmable microcontrollers, they’re just able to handle a simple communications protocol. There are quite a few different types of addressable LEDs, but two are most popular with makers: WS2812 (often called NeoPixels) and APA102 (often called DotStars). Both are widely available from maker stores and direct-from-China websites. NeoPixels use a single data line, while DotStars use a signal and a clock line. Both, however, are chainable. This means that you connect one (for NeoPixels) or two (for DotStars) pins of your microcontroller to the Data In connectors on the first LED, then the output of this LED to the input of the next, and so on.

Exactly how many LEDs you can chain together depends on a few different things, including the power of the microcontroller and the intended refresh rate. Often, though, the limiting factor for most hobbyists is the amount of electricity you need.

Which type to use

The big difference between NeoPixels and DotStars comes down to the speed of them. LEDs are made dimmer by turning them off and on very quickly. The proportion of the time they’re off, the dimmer they are. This is known as pulse-width modulation (PWM). The speed at which this blinking on and off can have implications for some makes, such as when the LEDs are moving quickly.

NeoPixels

  • Cheap
  • Slowish refresh rate
  • Slowish PWM rate

DotStars

  • More expensive
  • Faster refresh rate
  • Fast PWM rate
NeoPixels moving in the dark

As a NeoPixel is moved through a long-exposure photograph, you can see it blink on and off. DotStars – which have a faster PWM rate – avoid this.

Safety first!

HackSpace magazine’s LED feature is just a whistle-stop guide to the basics of powering LEDs — it’s not a comprehensive guide to all things power-related. Once you go above a few amperes, you need to think about what you’re doing with power. Once you start to approach double figures, you need to make sure you know what you’re doing and, if you find yourself shopping for an industrial power supply, then you really need to make sure you know how to use it safely.

Play multiple sounds simultaneously with a Raspberry Pi

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

Playing sound through a Raspberry Pi is a simple enough process. But what if you want to play multiple sounds through multiple speakers at the same time? Lucky for us, Devon Bray figured out how to do it.

Play multiple audio files simultaneously with Raspberry Pi

Artist’s Website: http://www.saradittrich.com/ Blog Post: http://www.esologic.com/multi-audio/ Ever wanted to have multiple different sound files playing on different output devices attached to a host computer? Say you’re writing a DJing application where you want one mix for headphones and one for the speakers.

Multiple audio files through multiple speakers

While working with artist Sara Dittrich on her These Blobs installation for Provincetown Art Association and Museum, Devon was faced with the challenge of playing “8 different mono sound files on 8 different loudspeakers”. Not an easy task, and one that most online tutorials simply do not cover.

These Blobs - Sarah Dittrich

These Blobs by Sara Dittrich

Turning to the sounddevice Python library for help, Devon got to work designing the hardware and code for the project.

The job was to create some kind of box that could play eight different audio files at the same time on eight different unpowered speakers. New audio files had to be able to be loaded via a USB thumb drive, enabling the user to easily switch files without having to use any sort of UI. Everything also had to be under five inches tall and super easy to power on and off.

Devon’s build uses a 12v 10 amp power supply controlled via a DC/DC converter. This supply powers the Raspberry Pi 3B+ and four $15 audio amplifiers, which in turn control simple non-powered speakers designed for use in laptops. As the sound is only required in mono, the four amplifiers can provide two audio tracks each, each track using a channel usually reserved for left or right audio output.

A full breakdown of the project can be seen in the video above, with more information available on Devon’s website, including the link to the GitHub repo.

And you can see the final project in action too! Watch a video of Sara Dittrich’s installation below, and find more of her work on her website.

Adding the Pi to Picasso with wireless digital graffiti

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

It looks like the Nintendo Wii Remote (Wiimote) has become a staple in many maker toolkits! Case in point: with the help of a Raspberry Pi and the cwiid Python library, David Pride turned the popular piece of tech into a giant digital graffiti spraycan.

Raspberry Pi-powered Nintento Wiimote digital art

Using the Wiimote with a Raspberry Pi

While it’s no longer being updated and supported, the cwiid library is still a handy resource for creators who want to integrate the Wiimote with their Raspberry Pi.

Raspberry Pi-powered Nintento Wiimote digital art

Over the years, makers have used the Wiimote to control robots, musical instruments, and skateboards; the accessibility of the library plus the low cost and availability of the remote make using this tool a piece of cake…or pie, in this instance.

Digital graffiti

Using aWiimote, a Wii Sensor Bar, and a large display, David Pride hacked his way to digital artistry wonderment and enabled attendees of the Open University Knowledge Makers event to try their hand at wireless drawing. It’s kinda awesome.

OK, it’s all kinds of awesome. We really like it.

Digital graffiti ingredients

To construct David’s digital graffiti setup, you’ll need:

  • A Raspberry Pi
  • A Nintendo Wii Remote and a Wii Sensor Bar
  • A power supply and DC/DC power converter
  • A large display, e.g. a TV or projector screen
  • A 30mm × 30mm mirror and this 3D-printed holder

Putting it all together

David provides the step-by-step instructions for setting up the Wiimote and Raspberry Pi on his website, including a link to the GitHub repository with the complete project code. The gist of the build process is as follows:

Raspberry Pi-powered Nintento Wiimote digital art

After installing the cwiid library on the Raspberry Pi, David connected the Pi to the Wiimote via Bluetooth. And after some digging into the onboard libraries of the remote itself, he was able to access the infrared technology that lets the remote talk to the Sensor Bar.

Raspberry Pi-powered Nintento Wiimote digital art

The 3D-printed holder with which David augmented the Wiimote lets the user hold the remote upright like a spray can, while the integrated mirror reflects the IR rays so the Sensor Bar can detect them.

Raspberry Pi-powered Nintento Wiimote digital art

The Sensor Bar perceives the movement of the Wiimote, and this data is used to turn the user’s physical actions into works of art on screen. Neat!

If you’ve used the Nintendo Wiimote for your Raspberry Pi projects, let us know. And, speaking of the Wii, has anyone hacked their Balance Board with a Pi?

On a completely unrelated note…

How cool is this?!

Елхата у Иванови, времето, животът

Post Syndicated from nellyo original https://nellyo.wordpress.com/2018/12/01/%D0%B5%D0%BB%D1%85%D0%B0%D1%82%D0%B0-%D1%83-%D0%B8%D0%B2%D0%B0%D0%BD%D0%BE%D0%B2%D0%B8-%D0%B2%D1%80%D0%B5%D0%BC%D0%B5%D1%82%D0%BE-%D0%B6%D0%B8%D0%B2%D0%BE%D1%82%D1%8A%D1%82/

IMG_2969-0

На 25 ноември в галерия Структура беше открит   Пети фестивал-лаборатория NEDRAma International, като тази година темата на фестивала е  Медии и свобода на избора.

Фестивалът започна с Елхата у Иванови,  съвместна творческа акция на театър “Реплика”, режисьора Javor Gardev / Явор Гърдев и визуалния артист   Teodora Simova. Според анонса “тази творческа акция използва за своя основа едноименния драматургичен опус на А. Введенски — кратък протоабсурдистки текст, писан в края на 30-те години на XX век”, преводът е на Георги Рупчев и е публикуван преди време в Ах, Мария.  Введенски заедно с Хармс е представител на ОБЭРИУ (Объединение Реального Искусства), пред нас е обэриутска драматургия.

Сюжетът: става дума за престъпление и наказание, за Явор Гърдев това е  углавно действо.  Зрителите са оградени с характерните за местопрестъпление полицейски ленти – това е местопрестъпление: в навечерието на Рождество, докато родителите са на театър, бавачката убива едно от децата с брадва,  след което е арестувана и осъдена на смърт.  Нейният годеник с приятели идва от гората с коледна елха,   родителите също се връщат –  и всички умират.

Елхата у Иванови не е разказ за Иванови, такива герои няма. Децата в пиесата са от 1 до 82 години, действието се развива в един ден, но има време за цял съдебен процес, а на финала става ясно, че за времето на действието дървосекачът Фьодор е научил латински и започва да го преподава в училище.

Времето, смъртта и Бог са централни теми за Введенски. Двамата с  Хармс работят върху спектакъл  Моя мама вся в часах, Елхата у Иванови също е в часах, а по-късно в поезията си (Кругом возможно Бог) Введенски казва  :

Вбегает мёртвый господин

и молча удаляет время.

И пак там – за съперничеството на смъртта и времето:

Мне всё чаще и чаще
кажется странным,что время еще движется,что оно еще дышит.
Неужели время сильнее смерти.

Елхата у Иванови е за Рождество, но Рождеството в пиесата е крайно условно, а рождествената песничка е особена:

 …молитесь колесу,
оно круглее всех!

Отново след Квартет Явор Гърдев включва медията в разказа – за изграждане на цялата пред-Рождественска условност. Паралелно с актьорската игра  на голям екран изображения рамкират или позиционират действието. Изображенията се сменят бързо,   разказите са паралелни, дори брадвите в разказите са паралелни – за момиченцето и за елхичката – човек едва смогва  да следи  посланията, трябва време да разбереш какво виждаш,   а разказите се застигат и допълват,  не е забравен и Джон Ленън –

God is a concept
By which we measure
Our pain
I’ll say it again
God is a concept
By which we measure
Our pain
Барбара Крюгер  (Your body is a battleground) дава голямата рамка на диалозите, а  в светлинния  надпис, под който завършва акцията –  
Too late to die young
отново присъстват времето и смъртта.
Введенски  пише в началото на последната девета картина:  защо да се огорчаваме, че са убили някого, като всички умират:
Петя Перов. Така ми се иска да умра. Просто страст. Умирам. Умирам. А така, умрях.
Нина Серова. И аз. Ах елхичке, елхичке. Ах елхичке, елхичке. Ах елхичке. Е, това е всичко. Умрях.
Пузирьов-баща. И те също умряха. Разправят, че дърварят Фьодор се изучил и станал учител по латински език. Какво става с мене. Как ми  прескочи сърцето. Нищо не виждам. Умирам.
Пузирьова-майка. Какви ги приказваш. Ето виждаш ли, човек простонароден, а постигна своето. Боже, колко тъжна ни излезе елхата. (Пада и умира).
Ако трябва да бъдем точни  – и въпреки авторовото твърдение в текста – умират всички без Варя Петрова – което може да се установи само при внимателен прочит на пиесата. Пишем и това на сметката на абсурдите.
Елхата у Иванови е създадена в края на 30-те години, в мрачно време – и затова критиците виждат в текста и реквием за руската цивилизация.
Текстът за пръв път е игран през 1987 г. в Москва.

Echoing the Newcastle of yesteryear with Pi-powered whistles

Post Syndicated from Alex Bate original https://www.raspberrypi.org/blog/steve-messam-whistle/

Artist Steve Messam is celebrating the North of England’s historic role in railway innovation with 16 Raspberry Pi–controlled steam engine whistles around the city of Newcastle.

Steve Messam Raspberry Pi Whistle The Great Exhibition of the North

The Great Exhibition of the North

The Great Exhibition of the North is a summer-long celebration of the pioneering spirit of the North of England. Running over 80 days, the event will feature live performances, exhibitions, artworks, and displays of innovation from 22 June – 9 September 2018.

As part of the celebration, artist Steve Messam is introducing his Whistle project in Newcastle in honour of the North’s part in the innovation of the railway. “Listen out for the evocative sound of steam engine whistles once again echoing across the city of Newcastle,” states the project page of The Great Exhibition of the North. “The sound installation is designed to recall the role of the North in engineering and the invention of the railway, sparking memories and forging links between past and present.”

Whistle

Steve first developed the idea for Whistle as a pitch to the Loch Lomond and The Trossachs National Park back in 2014. He originally wanted to install a line of whistles along the 22-mile course of the old railway line between Callander and Glen Dochart, with whistles sounding off in one-second intervals, recreating the sound of the old line.

Below is a very nice roundup of the initial 2-mile test run, including the original whistle designs.

Fast forward to 2018 and The Great Exhibition of the North, where Steve is surrounding the city of Newcastle with 16 newly casted brass whistles. The new installation follows the old city wall of Newcastle, with each whistle sounding at exactly 1pm on every day of the exhibition.

Original plans for the whistle

The William Lane Foundry cast the 16 whistles to match a design by William Armstrong based on measurements of an original whistle held by the North East Locomotive Preservation Group.

Each whistle is equipped with a Raspberry Pi that controls the release of compressed air through the brass to replicate the sound of a steam whistle.

Each unit is powered by solar panels and registers the time from the National Physical Laboratory’s atomic clock in London to ensure accurate timings. As a fallback in case of WiFi issues, the whistles are also linked to the clock set on the Raspberry Pi itself.

The more I think about it the more I really like that ‘Whistle’ only really exists for about 20 seconds each day.
