Five early woven QR-code bands

Weaving experiment session #13

Bandgrinding

Bands are arguable the earliest woven textiles. Bandgrind is the Swedish word for a band weaving tool a.k.a. a rigid heddle. We logged our rmQR bandgrinding experiments.

Quipus

The Padonma Network is encoding digital data into handwoven structures, that is QR Codes in bands. Curiously this is nothing new. The Incans were doing the same centuries ago.

Since rMQR codes can be narrow, they can be woven into bands easier that the original square QR codes.

We needed to prove that handwoven rMQRs codes would actually be scannable

Future Weaving

We have proved that rMQRs can be handwoven. Next better, faster, easier.

Session #14

Session #14

Sixth time’s a charm, it seems

Session #13

Session #13

The first full QR completed unfortutely proved unscannable

Session #12

Session #12

Basic techniques seemed good enough so we started working on a full rMQR code

Session #11

Session #11

Band Five starts on a new higher capacity heddle

Session #10

Session #10

New bigger heddle, Band #5 starts.

Session #9

Session #9

Band Four starts: experimented with complimentary warp pick-up and pixels being 3 warps wide

Session #8

Session #8

Time came to adopt warp-faced weaving techniques, as weft face does not make nice QR modules

Session #7

Session #7

We had figured out the weft needed to be thicker so we tried 1 mm

Session #6

Session #6

Band Two starts: wool proved too stretchy for crisp patterns at small scale so next experiment was cotton

Session #5

Session #5

A second attempt at a QR start finder square

Session #4

Session #4

Semi-square but misaligned pixels start getting assembled into QR structural components

Session #3

Session #3

Pixel aspect ratio experiment

Session #2

Session #2

Band One continued while attempting to make pixels a.k.a. QR modules

Session #1

Session #1

Band One starts: first thing we tried was wool, which was way too stretchy
