Thermochromic ink on and conductive thread
Thermochromic painted as the leaves of a tree with conductive thread attached the back of paper to heat it and make the leaves disappear.

Piezo as a vibration sensor
I’ve been testing out using a Piezo as a vibration sensor so that I can use it to detect wind and movement in plants. I’ve adapted a circuit and the code from the Arduino ‘Knock’ tutorial to work on a ATTiny85 to make the circuit smaller. The piezo can be made very sensitive by altering the code - here its sensitive enough that it works when I blow through a straw onto it - I did this to see if it would be sensitive enough to pick up on light wind / breeze outside.

Trying out ideas for light-up paper sculptures.
I’ve been trying out different ideas for a paper sculptures workshop - the sculptures will light up in the dark (using the circuit from my last post). I’m going to use different thicknesses and types of paper but also paper that has been laser cut and hand cut to cast shadows and patterns.

Paper Circuit turns an LED on in the Dark
Testing out a paper circuit for a workshop - the circuit uses a light dependent resistor to switch an LED on in the dark. The circuit is going to be used as part of paper sculptures which will light up in the shade or when the sensor (a light dependent resistor) is covered. I’ve used copper tape and ‘bare’ conductive paint to make the connections. The LED looks lot brighter out out of direct sunlight.


The circuit I’ve used is based on this Instructable:

Vibration Motors with Arduino 
I recently took part in the  Urban Media Lab at IMAL in Brussels.  I was working with Sam Jones and Neil Winterburn creating a haptic belt for Sam’s SuperForager project.  Here the motors are hooked up to the arduino and a motor driver.  Later we used a compass module to control the motors, triggering them to indicate north.  We based out design on this instructable:  http://www.instructables.com/id/How-to-Make-a-Tactile-Feedback-Compass-Belt/

Makey Makey Leaf Piano

Trying out a makey makey using garageband to make a leaf piano where each leaf triggers a different piano key  using ‘musical typing’ in garageband.  the leaves could be programmed to make different sounds by using soundplant.

Prototype at FACT
During the summer holidays I worked with Neil Winterburn to deliver Prototype at FACT.. A three day programme of activities for young people which explored ideas of hacking and inventing. This included an introduction to smart materials and e-textiles. We looked at different smart materials; thermochromic (heat sensitive), photochromic (light sensitive) and hydrochromic (changes with water) and how they have been used by artists and designers. They then explored their own ideas using the different smart paints and materials provided. Ideas included: a dragon headband that changed colour with sunlight, bags that blossomed in the sunlight, a bag that changed colour if your drink leaked, shoes with flames that appeared in the heat and many more…
