LGM 200 words

From digital to knit,
    “an erruption of the digital into the physical ”*

    How do pixels, vectors, snippets of code transform into a jacquard knitted stitch?
    Textile design asks for a specific way of designing images. Only since 2010 older (means produced in the 1980's) electronic domestic knitting machines can be hacked to knit images via usb. There are constraints to take into account such as 200 needles implies 200 pixels, bitmaps...
Main design axes to experiment with in the workshop:
- Aperiodic & generated patterns, loops...
- Photograph to knit & legibility
- Digital font to knit
We will be looking at conversion tricks, dithering algorithms for black & white pixels, splitting and adding lines, the png & bmp format, the very low resolution, maximum 2 colours on a row.

This workshop will be a hands-on moment of exchange, as Lgm Toronto definitely houses a lot of knowledge on font design and image producing, generating etc..
We are interested to help the knitting community, from the hobbyist to the professional textile designer, and share this open source workflow as the proprietary equivalent lack imagination and flexibility. We combine open hardware and Floss.

    From digital to knit ,
    an erruption of the digital in the physical

    How do pixels, vectors, snippets of code transform into a jacquard knitted stitch?
    Textile design asks for a specific way of designing images. Only since 2010 older (means produced in the 1980's (Brother kh910 - 1980 & Brother kh940 - 1988) electronic domestic knitting machines can be used to knit images via usb. If we use these hacked brother knitting machines (with Ayab - or knitting in combination with a ftdi to serial cable), the constraints are the following:
        - 200 needles (implying to 200 hundred pixels)
        - unlimited length (with lack of muscle power and yarn shortage as restrictions)
        - 2 colours
        - rectangular pixels that become a v-sha pe
        - a knit is not flat - adding different textures, sizes of yarn or tension creates body and layers compared to the flat knitting chart.
        - what the machine understands via the hack: (black and white) bitmapped pixelbased images, legible by the software you use to send to the knitting machine

        In this hands on workshop we will experiment with the design process of knitted textiles. We will design images to be knitted and look at the problems and potential solutions in this translation process. There are several starting techniques:
- Aperiodic patterns, infinite loops, cellular automata and other code generated patterns
- from photograph to knit and how to keep the image legible in yarn
- from digital font to knit - on restrictive font design

We will be looking at conversion tricks, dithering algorithms for black & white pixels, splitting and adding lines, double length or width, the png & bmp format, other constraints, the very low resolution, not more than 2 colors on a row.

We see this workshop as a hands-on moment of exchange, as Lgm Toronto definitely houses a lot of knowledge on font design and image producing, generating etc..We are interested to helpt the knitting community, from the hobbyist to the professional textile designer, and share this open source workflow as the proprietary equivalent lack imagination and flexibility.

Software used: Gimp, imagemagick???

------------------------------------------------------------------------------
   How can these open source tools can help the knitting community from the hobbyist to the professional.
   As a summum, we will try to generate some illusion knitting. https://en.wikipedia.org/wiki/Illusion_knitting

    -from digital pixels to Knitted stitches
    -Converting, Scripting, generating, processing digital images to convert for a jacquard knit. Imge Resolution vs machine knitting width and needle gauge.
    -What the hacks suddenly allows us : infinite in length patterns or images - aperiodic patterns - infinite loops. Texte, photos, drawings

    Tools usually used: Dithering algorithms for black & white pixels - splitting and adding lines- double length or width - png & bmp format -
    constraints - resoluition, not more than x2 colors on a row
    ex: illusion knitting

--> y a déja eu un talk similaire en 2010 : http://www.libregraphicsmeeting.org/2010/index.php-p=en |talk|fashion_design.html
hmm oui et non

c'est encore en brouillon:

How can open source tools for textile and fashion design can help to reimplemante local production and allow designers to improve research and create unexpected designs?
How can designers be able to invente the appropriate tools matching their own needs and technics.?
Machines that are available for small designers to knit, weave, knit, embroider ..their patterns or textures are very expensive and come along with propriatary software (also very expensive) that is very obvious / basic (1er degré) which makes it difficult to invente or adapt diffrently than traditional textile designs. These semi-industrial tools should however enable small designers to create and experimente things that couldn't be possible in textile factorys. A few open source projects have emerged to give alternative ways of designing patterns but also enabled obsolète machines to come back to life. Hacked kntting machines allowed us suddenly to make infinite patterns or be generated by other data, embroidermodder made an open source fomat for embroidery machines,..

In this presentation we will look at computerized knitting machines from the 80's and 90's. We will give an overview of how these machines got hacked, the physical computing aspect of these hacks, lingering hardware and software problems and the design process involved with using them. Some interesting projects will be highlighted.

In the 80's and 90's electronic domestic knitting machines were popular. These machines stopped being produced in 1996. Yet they are still being used with their 1980's and 90's technologies in contemporary textile design & schools, they are the best semi industrial way to prototype knitted fabrics.
The computing aspect of the machines froze in time, as the way of getting data in and out was very limited (remember Tandy) - until John Hogerhuis and Steve Conklin started getting interested.

From 2004 onwards the reverse engineering process developed gradually. We will give an overview of these different hacks and their issues.
    - 2004, kminternals yahoo group, John HogerHuis
    - 2009, contribution to kminternals yahoo group - later GPLv2, Steve Conklin, reverse engineering the proprietary format of the Brother knitting machines and lots more
    - 2010, Becky Stern & Adafruit: serial ftdi cable & hack of Brother KH-930e Knitting Machine
    - 2010 Fabienne Serriere, Travis Goodspeed and Arjan Scherpenisse, floppy drive emulator
    - 2012 Knitic - Mar Canet & Varvara Guljajeva, Processing based software & a shield for an Arduino Due
    - modified Knit Hack - So Kanno (+ Ck 35 hack in Etib), rewrites Knitic Arduino code and the software to communicate with the machine (processing)
    - 2014, Ayab, All Yarns are beautiful, develops Arduino Uno shields for Kh910 & more, using Python
    - 2014, Open Knit, Gerard Rubio makes an open source knitting machine almost from scratch

Quite a few projects have emerged from all these hacks, we will show our favourites, together with unraveling the design aspect which lies behind.

We will physically bring these hacks to the talk and we will demo them in our stand during the weekend of Fosdem. All of the hacks will be shown on a Linux machine, with different kinds of Floss flavours.

We are giving this talk with two people: Wendy Van Wynsberghe & Claire Williams. Both biographies are in the biography section of penta.fosdem in this profile.
Claire Williams is a textile designer, Wendy Van Wynsberghe makes installations with e-textiles. Both find the Floss aspect in our practice essential. We have organized workshops on hacking knitting machines and we have done several hacks. This is a talk directly from practice. The hacks are always experimental and ask for a direct dialog between designer and developer to troubleshoot the manyfold issues.

TBC, with the help of Constant (www.constantvzw.org) we will invite Ayab & Gerard Rubio from Open Knit. There will be a small exhibition opening on Thursday 29/01/2015 in Rue du Fortstraat 5, 1060 Brussels

==============================================================================================================

     along with how you go from a computer image to a knit.

We got really inspired by Steve Conklin's contribution to the Libre Graphics meeting, where he presented the hacks from a reverse engineering perspective - our presentation comes from a textile designer working with Linux, installing and using the hacks point of view.

In the 1980’s, domestic electronic knitting machines were the one of the 1st tools of semi- industrial fabrication that were made for the home. The analogue version/ More versatile machines used punch cards (model developed till 1979).
The Brother Electroknit models stopped be ing produced in the 90’s, the latest models were computerised . With those machines, (from model 910 - 970) You could manually programme or use prerecorded grids of patterns. The manual programming had to be done pixel by pixel which made impossible to knit a non periodic pattern such as a photo.

One type of machine (910) had an optical scanner that can interpret a grid of 60 pixels wide & 150 pixels high.
In 1996, the last computerized electroknit was made.

How to send a pattern from your modern computer to the knitting machine? How to reverse engineer a proprety format?
---> Ftdi cable
The limit's of the machines original computer: size, number of pixels/stitches.
---> Totally controlling de machine from a computer: re designing the electronic circuit and shielding it with Arduino
This allows to go beyond traditional pattern designing and directly transform any data in black & white pixels to be sent to the knitting machine
