EXPERIMENT 1 | DAISY BUD
I created a series of flowers with yarn, conductive yarn and conductive thread. The white one, slightly different has a little bit more of experimentation using different stitches and materials ( conductive yarn + conductive thread). I can totally tell which one was the first and which one was the last one!
Materials. Color yarn, crochet needle, conductive yarn. Testing circuit: led, alligator clips, sewable battery holder and 3V battery.
Technique. I used the colored yarn for the base flower using the simple and double stitch, and conductive yarn using the simple stitch to create an attachment to the main flower that could create the connection between both ends.
EXPERIMENT 2 | DANCING DOT
This flip dot aimed to resemble a dancing small flower. The crochet technique used to cover the coil helps to visualize small petals made of yarn and the flower core made by the bead.
Here a clear shoot changing the polarity from one coil to the other making the bead go back and forth.
1. For my circuit, I used a double coil made by more than 100 turns each.
2. Before crocheting the cover I labeled the wires to be able to, later on, connect it to the batteries to add the current and consequently motion.
EXPERIMENT 3 | THERMOCHROMIC INK
EXPERIMENT 4 | SOFT CIRCUIT SPEAKERS
For my speakers, I decided to work with known substrate and conductive material such as conductive copper tape and paper. However, I tested different patterns.
EXPERIMENT 5 | BREATHING X-MAS TREE
My idea for this project was to bring to life a tiny Christmas tree. Winter season is here to stay for a couple of months but Christmas trees will join our households just for a couple of weeks. I was planning on keeping the tree alive by interacting with it.
This is the circuitry: heating circuit + swatch + Flexinol + 9V battery.
EXPERIMENT 6 | PRESSURE SENSOR MATRIX
1. 2 X 2 pressure sensor matrix using cardboard, Velostat, conductive tape ( pattern 1 )
2. 2 X 2 pressure sensor matrix Velostat, conductive fabric ( pattern 2 )
TEST 1 - WHACK THE LIGHT
Whack the light’s goal is to play a whack-a-mole-game with LEDs instead of physical targets. It consists of a game without a screen created using a child’s interlocking foam floor mat that acts as both the controller and a 4x4 resolution display made of addressable LEDs.
I created a 4 by 4 matrix using 4 digital pins and 4 analog pins. I used Velostat in between to perpendicular conductive lines to detect the difference on resistance when that particular cell was pressed. The Velostat is used to change the resistance when pressure is applied, so when someone steps on a square the change in resistance tells us where in the matrix they are stepping. I achieved to have accurate feedback in more than a cell at once.
TEST 2 - PRESS THE CRUST
3X3 pressure sensor matrix surface made of conductive tape and felt
