A lot of fun was had making these silhouette-paper-lanterns at Farnham Festival of Crafts. We made simple circuits using coper tape, and a bit of conductive ink to glue (I mean *cold solder*) the components.
Here is the final version of the Craft Connects book! Play the video link to see it in action. I am especially happy with how the knitted triangles came together. The cover looks fantastic, and when you link the letters C R A F T to the knitted triangle labelled “connect”, you trigger sound-bytes from Farnborough residents about why they like to get involved in crafts.
The book was exhibited at Farnham Maltings Festival of Crafts in October, and will be on display at Farnborough library for their 40th Anniversary celebration in December.
Plug in your book?! When the battery gets low, you can charge it using a micro USB.
To make the knitted book cover I had the the help of the Farnborough knit and natter group, and the Nepalese craft group. Both groups worked together to make loads of triangles, which I then stitched together.
English and Nepalese casting on techniques are quite different, and the two groups learned from each other.
I laid the triangles out in ordered rows according to size. We made all of these (above) in one session. I didn’t think we were going to have enough to cover the book, until a library staff member delivered this package (below) -a carrier bag full of neatly knitted triangles from the nepalese craft group. Amazing!
And finally, I stitched “C R A F T” to the cover. I used conductive thread to make the crouching stitch, which formed the shape of each letter. Each letter was then connected to a trigger pin. I also stitched “connects” to a triangle which is connected to the ground pin (see my diagram to look at how this related to the other circuits). When the “connects” triangle connects with any of the C R A F T letters, it triggers an mp3.
To connect the hardware with the book I used conductive thread. I chose to buy it from kitronic in the end, as it has a relatively low resistance, it does not unravel easily and a good price!
First I stitched it to felt.
Look at the messy back! I hid some of the wires under the felt.
Then, I stitched both the circuits and the felt to the book, and connected to the conductive threads I had already sewn into the spine (see post on binding).
A diagram of the connections (above) and the finished stitching (below).
Ohhh. look at the (kind of neat, almost good, getting there, bit on the long side) soldering!
Another tricky part of the process was connecting to the pins -i.e. making a breakout board for conductive thread. After a skype “consultation” with Seb and Hannah, who both work on a really exciting glove project and are experts in e-textiles, I decided to solder wires to the live pins, and then padded them with felt to stop any breaks or shorting.
I then made loops on the wires to connect the conductive thread to (inspired by the wire-loop/thread in this example).
Binding the book was no easy task. Originally, I had planned to bind using coptic technique which I had learned from one of the studio technicians when studying at Leeds College of Art. This would have worked by binding the book as usual, whilst also working the circuits into the back of each page with a similar stich. This did not work.
So, instead, I used a concertina fold, inspired by an old favourite of manual of mine: Non-Adhesive Binding: Books Without Paste or Glue (although, I used both paste and glue!). By creating a concertina spine I could sew the circuits along the width of the spine, and they would stay very firmly on their own tracks -minimising any interference. This also strengthened the spine of the book, and made it is easy to fully open pages.
So we have lots of creative work by members of Farnborough library, we have some stories and sound bites, and we have a small device to play these back. Now to put them all together and make the book!
We made 18 sound recordings in total, and I saved these recordings with the file name 001-018. These are stored in the mp3 trigger device. I then made 18 circuits and connected them to the pins 1-18. When closed, each circuit triggers the corresponding sound recording -i.e. recording #018 is triggered when the circuit connected to pin #18 is closed. I based all the switches on traditional pop-up techniques. Here are a few:
