Exploring thermochromic colors.

I made 3 switches which can be turned on by shaking hands.

For the final project, I made a switch which could be triggered by human touch the feather.

Material:

• Wood sheet;
• Feather;
• Copper Tape;
• LEDs;
• Hot Glue;
• Soldering tools;
• Wires;
• 3V battery;

Process:

I did spend some time thinking about the circuit of how can make it work.

First I know that I need parallel; But where to put the break (switch) and also incorporate with the aesthetic placement of the LEDs is a little bit tricky. I only want to light up one LED at a time when the feather touching on one corresponding switch.

Finally the circuit work out like this:

Start placing the LEDs on the wood sheet. Facing different directions to light up.

Adding feathers layer by layer.

Thermochromic ink exploration.

I created 5 pieces of swatch for this assignment.

For this week I constructed there pieces of speakers with different substrate materials for homework.

It was fun. Love to see the feather dancing when the speaker is on and vibrating.
