My final project was to reveal a word made up of copper thread, using thermochromic color and heating circuit.

Here is my instructable link:  link: https://www.instructables.com/editInstructable/publish/E4KGABDJPX4RLGG

Materials used in this project:
– Arduino
– Ultrasonic Sensor
– Cotton pieces
– Conductive Copper Thread
– Wires
– Thermochromic Color Pigmen
– Clear Acrylic Paint
– Colorful Acrylic Paints
– Mosfet Heating Circuit (connector between Arduino and the sewed copper wires)

For this assignment, I used regular paints to fill up the bottom layer and used black color thermochromic pigment mixed with a clear acrylic base to fill the top layer.

MIDTERM ASSIGNMENT: LAMP FOR A CLOSET!

  • link to Instructable website: https://www.instructables.com/id/Light-Hanger-1/

I often thought that I needed a separate light just for a closet. There were some situations when I did not want to turn on my room light to grab something out of closet.. especially not to wake up my roommate and pets. So I thought about creating a moveable light on a hanger.

I planned to make the circuit directly onto one of my shirts, however, it did not quite work out because the shirt was too stretchy. Instead, I used pillow case fabric to make a mini shirt that can be hung on a hanger.

I created a circuit using Flora, LED lights, and a button that controls turning on/off the lights. When Flora is connected to a battery, a button is activated to control the lights.

 Materials used:

  • Pillow cover
  • LED lights * yellow
  • Flora (arduino)
  • A button
  • Conductive thread
  • Conductive fabric
  • Copper thread

Future iteration:

  • make more than one state for lights. (ex: blinking, lights partially on, etc)
  • make both side of the shirt work (add more lights on the other side of the shirt)

  • Title. “Tight it to Light it!”
  • Description. This swatch (when light and the battery are in place) is to light a LED when the belt is tightened.
  • Materials. conductive fabric & paint & thread are used.
  • Techniques. Conductive threads are hand sewed onto a fabric that is used for embroidery.
  • References. I wanted to be creative with surface contact activated circuit. And thought a way of making two surfaces lock up to light the LED. (the belt!)

I’m using conductive paint spread on the fabric! and the thread.

belt type switch! using conductive fabric also. I liked that even a thin layer of the paint was able complete the circuit. I enjoyed hand sewing experience =].
