GUANG (Light) is an interactive wall installation that seeks to communicate different spaces, more specifically, the outside with the inside. Its goal is to help bring nature indoors, into our homes. With the use of pure white lights, the back panel lights up constantly luring the user into the space. Once standing on a pressure sensor placed under feet silhouette, a “rain of lights” surrounds the individual with beautiful organic shapes from nature.

Based on this prototype we got a chance to test the interaction, which led us to remove some difficulties from the equation. Now, instead of using felt pompoms as our pressure sensors, we will build a padded semi-sphere which will enclose several pressure sensors, and depending on how and where you touch it, it will trigger sets of lights and sounds in the installation. This will also give us more alternatives to hide the circuitry, for a better look+feel.

Here’s a small video of our working prototype.

Here is my circuit on breadboard.

It’s the circuit_pcb on PCB.

And it’s circuit_etch.

My favorite artist,  Cai Guo-Qiang, is an installation, interactive, performance artist. He made lots of amazing artworks and most of them include deep cultural self-reflection and historical allusions. And the most unique part of his work is that he uses gunpowders to draw. Here is his website.

So… for the digital input by using a button, I choose to use my 3D prism as a button.

I made it transform into a prime power prism… If its legs are put to the right place

on the bread board, it will be just like pushing a button. And I made 2 versions, one

is pull down, the other one is pull up.

Pull down


Pull up


Here’s the code

It’s an anonymous reindeer that was made by non-woven fabric. I use non-woven fabric, conductive

and resistive thread  in order to mimic the texture of fur. When you touch the fur, the stroke sensor is

fired, then its nose will turn to red.

For variable resistor sensor, I use the same reindeer, when it walks to the tree, the path is the variable

resistive sensor, it will control the LED on the tree, and light up the tree.

I made this police car with only one wheel and combine a switch and a pressure sensor with paper based circuit.

For the switch sensor, I use a battery as one wheel, when I put any 3 round shape metal, for example: coins

as wheels on the car , the circuit will be connected, then trigger the 2 green head light.

For the pressure sensor, I made it and the switch sensor parallel connected, so when the four wheels are put

on the car, then I can use the pressure sensor to control the fade in/out of the red  alarm siren.

Paper Based Circuits with Pressure Sensor

I put LED in the 3D twisted decagonal prism and exposure its legs outside of the prism

as a switch, later I upload a fade arduino code in the board and deal with the circuit.

If I put the prism on the bread board and let its legs on the right holes, the arduino

can detect the electricity, then the LED starts to fade in and out.

I embedded a wire in the small iceberg, when the ship hits the  iceberg, when means the pin

on the head of the ship contact to the wire in the iceberg, the switch turns to on, it’ll light up

the LED on the ship. Then you can use the pressure sensor on the other side of the boat to

control the dimming of the red alarm LED, like using it to send a Morse code something like
