Lab 3: Weaving Fundamentals

Lab 3 – Weaving – Groups of three.

Materials

  • 12” of Conductive Thread
  • 2 X 24” of different colored yarns.
  • Cardboard

Tools

  • 1 Loom with shuttle and heddle (Design your own).
  • 1 Multimeter
  • Illustrator

Your challenge in this lab is to take your knowledge of weaving and design your own loom to cut on the laser cutter. The requirements are:

  • It has to have a shuttle and a way to create a shed (IE, a heddle).
  • It has to be made from cardboard
  • The design has to have a vector cut and a raster etch. Inscribing your names to the loom counts as a raster etch.

Some of you will not have time to cut your project during class. Schedule a time with a fellow to cut the loom together.

Once you have made your loom, try to create some of the following weaves:

  1. A basic weave fabric with some conductive threads woven in.
  2. A twill woven fabric.
  3. A weave of your own design.

Lab 2: Beginning Sewing and Embroidery for Circuits

Lab 2 – Individual

Materials

  • 1 Coin Cell Battery
  • 1 Coin Cell Holder
  • 1 Pushbutton Switch
  • 1 LED
  • 220 ohm resistor
  • 12” of Conductive Thread
  • 1 Spool of regular thread
  • Wires

Tools

  • 1 Multimeter
  • Sewing Needle
  • Embroidery Hoop

Your challenge in this lab is to make a version of the circuit you made on the breadboard on a piece of fabric. Practice sewing on fabric first before jumping onto your fabric circuit.

  1. Outline where all the materials need to be placed and check the circuits to make sure they work in the arrangement you decide on.

  2. Sew the materials in place with regular thread using the couching method.

  3. Sew the connections together with conductive thread.

  4. If you have time, try thinking of different ways of replacing the pushbutton switch with means of closing a circuit.

Lab 1

Lab 1 – Felting with conductive materials

Materials

  • 1 Handful of wool roving.
  • 1 Coin cell battery
  • LEDs
  • 1 Pinch of conductive roving.

Tools

  • 1 Multimeter
  • Felting needles (or regular needle with nicks on the sides of it).

Your challenge this lab is to create a piece of fabric that you felted yourself. Felt together a piece of fabric for the base using the dry felting method. If you want to add conductivity to your felt, when the base felt looks about 3/4ths done, apply little by little a small amount of conductive fibers and felt them in with the felting needle. Check the resistance values using a multimeter until it gets to your desired value. Remember, the density of your conductive fibers will make a difference here.

You may use your fabric for any project that you wish. One way of using the fabric is to create a resistor from the steel roving. Another example is to create a battery holder for a 3 volt coin-cell battery and power up an LED. To do this, you felt two pieces of conductive fabric together, forming a pocket for the battery. Make sure you are not short circuiting the battery.

Take photos and notes throughout the experience for documentation. We will go over posting your experience on the documentation blog next week. This is an individual assignment. Each person must create their own fabric and document their own work.
