Introduction: Weaving: Clasped Weft With LEDs

Picture of Weaving: Clasped Weft With LEDs

Another project for the weavers and hopefully a source of inspiration for the non-weavers.
Incorporate LED's, or other hardware, into your weaving project using the clasped weft technique.

Info Added 1 May 2009
An article in weavezine.com May issue has further information concerning this technique.
Please enjoy!

Step 1: Preperation

Warp the loom.
Wind a bobbin with one fiber and place in a shuttle. I am using a pink wool.
Wind a second bobbin with a different yarn AND conductive thread. This contrasting yarn is not necessary, but helps identify your different traces.
For this example I have used greenyarn/conductive thread
Solder crimping beads to your LEDs.

Step 2: Weave a Positive Trace to Attach LED

Raise the shed.
Weave a clasped weft bringing the pink yarn from the right and the greenyarn/conductivethread from the left side.
Feed the conductive thread thru the crimping bead.
Pull the conductive thread taught and pull the tail end, plus the green yarn, thru the shed to the left side of the warp.
Lower the shed.
Beat the warp...gently so as not to damage the LED.

Step 3: Weave in the Daisy Chain

Following your pattern weave a couple of rows the width of your LED.
Be sure to catch the greenyarn/conductivethread into the left selvedge.

Step 4: Weave the Negative Trace

Begin with the pink yarn shuttle boat on left side of weaving.
Bring a second strand of conductive thread from the right selvedge to the LED.
Clasped weft with the pink thread and conductive thread.
Feed the conductive thread thru the other crimping bead.
Position the LED within the weaving.
Bring the tail end of the conductive thread thru the shed to the right selvedge.

Gently beat the warp.

Continue weaving your pattern repeating daisy chain as desired being sure to match polarities on your traces and hardware.

Step 5: Test Test Test

Test your circuits and make something groovalicious!

YES you can!!

Hopefully this blog post will point you in the right direction.

Any pictures of it done and lit up?

Funny you should ask OrangeKid - I used orange LEDs that I had left over from Hippiepunk. Unfortunately, these orange LEDs, are not so bright. When I took the pics of the powered LEDs they were not bright enough to document. Sorry 'bout that.

Just switch off the lights!!

Even better, stick the camera on a tripod, do one shot with the lights out, and another shot with the lights on... superimpose & brightness/contrast each of the images.

This reminds me of the old hand-woven supercomputer RAM.

Wow! Cool! Textiles with pre-integrated electronics, I like it! How easy is it to weave/ build your own loom? I may way to experiment with this >>

Thanks!

Unfortunately, not so easy to build a floor loom like I used for the ible.
A back strap loom might allow you to experiment on your own with little investment.

Or you might get a small loom like a potholder loom (only get the metal ones) beading loom or a tapestry loom.

Have fun and please let me know how your project progresses.
