Light-up Sculptures with St Helens Family Art Club
We built paper circuits with LED’s and a light dependent resistor to make sculptures that which light up in the dark. The circuits were built on top of the instructions using copper tape and bare conductive paint so everyone could have go at making them. We then built the sculptures using different types and thicknesses of paper, cutting out patterns and using paper that had been laser cut with designs for the light to shine through.
Thermochromic ink on and conductive thread
Thermochromic ink 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.
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.
