Raspberry Pi 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 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

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.
