Machine Knit With Wire

I've been working on a method to machine knit with copper wire, for creating eTextiles.

the challenge:

  • wire needs to come off the spool with zero drag
  • 30-36 AWG magnet wire is super thin and breaks easily, also tangles
  • magnet wire spools are heavy, which means inertia and momentum if the spool spins, which will snap or tangle the wire.
  • it's got to be cheap

the solution (so far):
  1. place the spool on the floor in front of the machine
  2. mount a wisker disk on the top of the spool
  3. place a guide hoop above the spool for the wire to pass through
  4. attach a light-weight rope thimble to the tension mast, to minimize bending of the wire

things to improve:
a better stand
experiment with larger rope thimbles (maybe 3D print?)

I based this design on industrial coil winding methods. For instance:

This research has been a part of my Public Engagement Maker Residency at UIC/Mana Contemporary, working with Professor Sabrina Raaf. Also, props to Ed Bennett, for pointing out the tension mast wire-bending issue.
