3D Knitting from a 3D Computer Model

Yuki Igarashi, Takeo Igarashi and Hiromasa Suzuki already published in 2008 a way to convert 3D models into knitting models in their presentation in Japanese "3次元モデルからのあみぐるみ生成 - 五十嵐 悠紀,五十嵐 健夫,鈴木 宏".

Video in Japanese: http://youtu.be/xJyZ3XQkrh4

A knitted animal is made of a closed surface consisting of several knitted patches knitted out of yarn and stuffed with cotton. We introduce a system to create a knitting pattern from a given 3D surface model (mainly designed for rotund animal models). A knitting pattern is an instructional diagram describing how to knit yarn to obtain a desired shape. Since the creation of knitting patterns requires special skill, this is difficult for nonprofessionals. Our system automates the process and allows anyone to obtain his or her original knitting patterns from a 3D model. The system first covers the surface of the model with parallel winding strips of constant width. The system then samples the strip at constant intervals to convert it into a knitting pattern. The result is presented in a standard visual format so that the user can easily refer it during actual knitting. We show several examples of knitted animals created using the system.

2D Patterns and 3D Forms - Sensitive Couture for Interactive Garment Editing and Modeling

This paper about "Sensitive Couture for Interactive Garment Editing and Modeling" is amazing and the source code is available (but not with an Open Source license as far as I can see). It is published at ACM Transaction on Graphics, Proceedings of SIGGRAPH 2011 by Nobuyuki Umetani, Danny M. Kaufman, Takeo Igarashi, and Eitan Grinspun. This is the future of pattern making.

Abstract: We present a novel interactive tool for garment design that enables, for the first time, interactive bidirectional editing between 2D patterns and 3D high-fidelity simulated draped forms. This provides a continuous, interactive, and natural design modality in which 2D and 3D representations are simultaneously visible and seamlessly maintain correspondence. Artists can now interactively edit 2D pattern designs and immediately obtain stable accurate feedback online, thus enabling rapid prototyping and an intuitive understanding of complex drape form.(http://www.cs.columbia.edu/cg/SC/)

Arduino and Knitting Machines AYAB Graphic Interface Project

The goal of AYAB-Knitting is to be able to program a knitting machine (currently brother 9xx models) with an image from a computer and extending the capabilities of the machines, e.g. the maximum 60 pixel image width. This is achieved by substituting the control of the needles and required identification of the current position and movement of the knitting carriage is substituted by a common Arduino microntroller, combined with a custom developed shield.

In the last few weeks, we were looking at different options to make it easier for users to work on knitting machines and we came up with an idea to develop a graphic user interface in cooperation with the AYAB project. Sebastian Oliva from Guatemala will work on this project over summer gratiously funded by Google. Thank you!

What is currently supplied:
- A transparent and lightweight API between the client computer and the Arduino, based on 115.2 kbaud serial communication.
- A proof-of-concept python implementation of the client-side of the API (the machine side is in the firmware of the Arduino).
- A simple python commandline application which uses this implementation.

Ongoing work, that will be supplied shortly as the basis for the GUI project:
- A simple PySide (Python+Qt) based GUI application which uses the API implementation, as a proof-of-concept and starting point for further GUI application development work. It will just have the same functionality as the commandline version, no fancy image processing or so.
- A new firmware version for the Arduino with a debug option to mock-up "end of line" events by pressing a button attached to the Arduino. No AYAB Shield, nor Knitting Machine needed for operation.


Video from Chaos Communication Congress 2013 (German), Deutschlandfunk ForschungAktuell

The goal of the AYAB project is to provide an alternative way to control the famous Brother KH-9xx knitting machines. There are some similar projects on the interwebs, such as Knitic or, of course, ladyada's electro-knit. The main drawback behind the existing projects is that they make use of the 930/40 series of the knitting machine - which are still pretty expensive. AYAB uses the older KH-910 model, which is cheaper than the other models, mainly because it features an error-prone scanner-mechanism for reading the image data (but we don't care because we won't use the scanner anyway…). The 930/940 series already use some kind of digital programming, which opens even more ways to hack them, other than what this project did. Normally, the KH-910 is programmed using semi-transparent picture cards which are scanned by the machine line by line. Using this information, the machine sets the needles accordingly to achieve the knitting of the picture shown on the picture card. Probably due to memory restrictions, the machine only supports pictures of max. 60 needles (= pixel) width, although the machine has a total width of 200 needles. At least, it is possible to “copy and paste” the scanned image multiple times to achieve a banner-like usage of the scanned data (useful for norwegian patterns). Now what we achieved is that you can just program the knitting machine with an image from your computer. The restriction of 60 pixel image width has been abolished due to the improved control. You can just knit an image with up to 200 pixel width. [https://bitbucket.org/chris007de/ayab-apparat/wiki/Home]

Couture Pattern Making Project in Java by Patrick Proy

Patrick Proy started an Open Source Pattern Making project in 2012. While it is currently (and maybe definitely) in pause, it is definitely of great value to look at his development ideas on the web. The project is in java and you can currently still have a look at it here : http://couture.proy.org/software_en.html

Open Fit: Custom Tailored Pants Patterns with Open Source by Kyle McDonald and Lisa Kori Chung

Open Fit Lab
https://www.flickr.com/photos/lisakori/9246715441/in/pool-2202673@N25 by Lisa Kori Chung

Open Fit is a project by Kyle McDonald and Lisa Kori Chung. Open Fit is open source software that investigates several approaches to generating custom tailored pants patterns. Open Fit Lab is an attempt to use this software for on-the-spot generation and creation of custom clothes. Our first Open Fit Lab will be, Fri. June 28, 8-10 @ 1265 Atlantic Ave. in Brooklyn. We will be exploring rapid prototyping and sewing of custom fit jeans as performance. By the Book is a traditional pattern drafting technique from a tailoring manual. It generates a trouser that is intended to be altered during the fitting stage. Draft From Center is an attempt to make this process more precise, and generate a fit closer to what is currently sold commercially. We are also exploring ways of modeling and flattening patterns in 3D.

Open Fit Lab Pants Project
https://www.flickr.com/photos/lisakori/9116993750/in/pool-2202673@N25 Lisa Kori Chung

How to use Open Fit for non-coders:

1. Download Processing: https://www.processing.org/download/

2. Download two additional libraries:
a) You can find toxilibs at http://hg.postspectacular.com/toxiclibs/downloads/ and put it in the libraries folder of your Processing sketches.
b) Download controlP5 http://www.sojamo.de/libraries/controlP5/ and do the same.

3. To view our work modeling pants in 3D, you will need the peasycam and modelbuilder libraries. Get Peasycam at http://mrfeinberg.com/peasycam/, unzip and put the extracted peasycam folder into the libraries folder of your Processing sketches.

4. Go to http://workshop.evolutionzone.com/2011/04/06/code-modelbuilder-library-public-release/ and look for a link to modelbuiler (0020). Also put it in your libraries folder.

5. The simplest way to grab our code is go to the github repository for Open Fit: https://github.com/kylemcdonald/OpenFit Extract and put the zip file you like into your Processing folder.

6. When you open up a sketch in processing you will see two buttons on the top left, Run and Stop. This is how you run and stop the code. Currently, you can change the measurements two ways. You can run the sketch and click on the numberboxes to scroll through possible measurements. The variables at the beginning of the code in Draft from Center and By the Book are the measurements that the code will initially draw the pants from. You can type in new numbers here and re-run the sketch.

Mosaic Knitting Pattern Generator with Processing.js

Processing.js is pretty cool.I found a Mosaic Knitting Pattern Generator from Laura Kogler.

This is a script to generate patterns intended to be knit using the two-color knitting technique known as "mosaic", or "slip-stitch", knitting. If you make something using this pattern generator, I'd love to know about it! You can email me (me[at]laurakogler.net), or hit me up on ravelry!

How to make a Pattern Editor - GeoGebra as an Example

Check out the new GeoGebra Google app. It has the exact functionality which the pattern editor should have:

GeoGebra is dynamic mathematics software for education in secondary schools that joins geometry, algebra, and calculus. On the one hand, GeoGebra is a dynamic geometry system. You can do constructions with points, vectors, segments, lines, conic sections as well as functions and change them dynamically afterwards. On the other hand, equations and coordinates can be entered directly. Thus, GeoGebra has the ability to deal with variables for numbers, vectors and points, finds derivatives and integrals of functions, and offers commands like Root or Extremum. It is a free and open source software.

Machine Knitting with Fabienne Serriere

Another video about machine knitting with brother machines with Fabienne Serriere from by Sam Muir in "Spring time" in Berlin 2012/13, which rather looks like winter though still ;-)

Machine Knitting with FBZ: Part II - In Deep Knit from Sam Muirhead.

This winter has been the longest and darkest in Berlin since 1951, so last month I paid another visit to Fabienne Serrière (FBZ) who you might recall from my earlier video as a hardware hacker and machine knitter extraordinaire. This time I had something of my own I wanted to knit. Inspired by Fabienne and Becky Stern and everybody else involved in hacking these machines, who built upon the work of others and then put their own improvements into the commons, I decided to draw on the commons to create an open source hat. ... One of many images from Snowflakes: a Chapter from the Book of Nature (1863) on the Public Domain Review. These images are certainly beautiful, but that was 1863, we’ve moved on a bit since then. Now, thanks to the aid of modern technology, we can finally present these snowflakes as the artist would have envisioned them, in glorious 1-bit duocolor [http://yearofopensource.net/snowflake-hat/]

Amazing Knitting Machine Hack Glitch Knit by Japanese

I found an amazing Knitting Machine Hack and production system by some Japanese artists and developers online called Glitch Knit. The team brings together Nukeme, a hardware engineer Tomofumi YOSHIDA, the software engineer So KANNO and a supporting member Emi YAMAMOTO.

The team uses a brother KH970 knitting machine, which was produced until 2005 and was discontinued afterwards. The parts list for hacking the machine:
* Arduino Due
* Connector : MicroBlade™ 53014-0810
* Photo interrupter : Sharp GP1S58VJ000F or compatibles
* Transistor Array : TD6208APG or compatibles

PCB
The team made circuit boards with a paperboard for prototyping with Adobe Illustrator and a Laser Cutter.

Glitch Knit Outcome

From the website description: This project divided into two main content. Firstly, by hacking a knitting machine, exposing the environment that can be output an image as knit by anyone. Secondly, by using the knitting machine that we hack, to make a “Glitch Knit”. The glitch is "damaged of data or machinery" and "damaged data but possible to play". The “Glitch Knit” has two different way. One is output of the digital image data which was glitched. The other is to damage the structure of lace knit. It is output as knit full of holes. Knitting machine that is hacked, is introduced as a new equipment in FabLabShibuya, and how to hack is also published on Github and Instructables. In this project, knit work is also the work, and the environment itself for making the knit is also work. This is a kind of digital fabrication, extension of the handicraft, and device hacking. And more this is the one of methodology for fashion design and a thing descended the glitch movement. (http://www.glitchknit.jp/#about)

このプロジェクトは、内容としては大きく2つに分かれています。1つ目は、ニッティングマシーンをハックし、誰でも画像をニットとして出力できる環境を公開すること、2つ目は、ハックしたニッティングマシーンを使ってグリッチニットを作ることです。 グリッチとは、”機械やデータの破損そのもの”や、”破損しているけれど再生が可能な状態”のことを指します。 グリッチニットの制作方法は2つあります。1つはグリッチした画像データを、ニットとして出力したもの。もう1つはレース編みの構造を破綻させ、穴だらけのニットとして出力したものです。 ハックしたニッティングマシーンは、FabLabShibuyaに新たな機材として導入され、そのハックの方法も含めて公開されています。 このプロジェクトでは、ニット作品も作品であり、ニット作品を作るための環境自体もまた、作品です。 これはデジタル・ファブリケーションの一種であり、手芸の延長であり、デバイス・ハッキングでもあり、かつ、グリッチ・ムーブメントの流れを汲んだもので、そしてファッション・デザインのための一つの方法論です。

Electronic Textile Institute: Designer Maker Community in Berlin

I read about the people from the Electronic Textile Institute in Berlin already a while ago. I was excited to have the chance to meet Victoria Pawlik in the space in Berlin Wedding on Saturday together with Andre Rebentisch from the Berlin Startup community.

Victoria Pawlik, Berlin Electronic Textile Institute

The group working at the space is still small, but the projects they are doing are already very exciting. Victoria studied fashion design and uses the places as a creative space to develop ideas and produce cloth designs, which she sells at community markets and online shops like VLP-Designs at Dawanda and RedPinkGreen at Etsy.

Other people at the space are coming from the IT and hackers community. Fabienne is known for her involvement into Open Source and Open Hardware. She likes to hack into knitting machines and creates incredible patterns, that are unique in every aspect. One of the designs at the shop is particularly interesting as none of the pattern parts repeat itself.

By Open-Sourcing older Brother knitting machines and connecting a PC to a machine Fabienne was able to enhance the functioning and extend the functionalities beyond the original one.

Internet Startup Companies Will Find Haven in Berlin

Germany’s mobile internet advertising is on the rise. Bundesverband Digitale Wirtschaft (BVDW) said in its MAC Mobile-Report 2013/01 that Germany’s mobile ad spending reached €62 million in 2012. This figure is expected to rise by 70% or €105 million before 2014. This is one big reason why many local companies are switching to go online. Mobile internet in Germany is now on its all-time high, and a lot of businesses already jumped ship by pushing some of their advertisements to the mobile market. If you’re an owner of a startup company, you might have heard lots of advice about online business. However, you may not have yet heard this advice from others: if you want to start a business in Germany, the best place for you to start is Berlin.

Berlin

Aside from thousands of local German firms starting their online businesses in Berlin, companies from London, Venice, Paris, and other European cities think that Berlin is the next biggest hub for online ventures, thus starting a movement called the “Berlin Startup Scene”. Among the ventures that found paradise in Berlin are Motain, Rocket Internet GmbH, photo sharing app EyeEM, and mobile messenger app Zoobe. These companies started with a very small number of employees but have since expanded after trying their luck in Berlin. The Berlin Startup Scene goes like this: starting companies open their business with a capital ranging from €75,000 to €377,000 and with a very good business concept, the particular business will be given the chance to grow through financial aids from bigger German companies who can see the potential of their ventures.

News of Berlin as a great techno hub has spread all over the globe. Even some companies in the United States—which is perceived by many economies as one of the centres for mobile growth—are predicted to try their luck in Germany. Bally Technologies and iSoftbet, two of the biggest gaming technology providers in the US, teamed up to conquer Germany and other European nations. Under the agreement, the two software companies will form a united front to bring online slot machines and other betting games in the Eurozone. Their gaming applications won’t have a hard time penetrating the European market as people there are also fond of mobile games like poker, bingo, casino, and lottery. Poker websites like partypoker were introduced to the country in the middle of the last decade but they are already among the most played. This is mainly because of the German government’s efforts to help local or foreign websites in fulfilling their goals.

If you are looking for a place to start your online project, you should take a chance in Berlin. Who knows, you might just find your luck there?

Knitting Machine Creations by Fabienne Serriere

Sam Muirhead published a great video picturing Fabienne Serriere's work with knitting machines.

Fabienne's Hacked Knitting Machine Creations! from Sam Muirhead on Vimeo.

Once upon a time, there was a warm, fuzzy hack. It was 2010 – Becky Stern and Lada Ada (Limor Fried) built on Steve Conklin’s disk emulator and knitting machine resources to allow their modern computers to work with the ancient microcontroller of a 1980s knitting machine. This meant that they could now knit designs made with modern tools, too complex or tedious to easily knit by hand. They shared their work with the world and since then, following an open hardware model, they and many others have contributed hardware and software improvements, smoothed the workflow, and allowed other models of knitting machine to be hacked. I went for a beautiful autumnal bike ride over to Wedding and caught up with Fabienne Serrière (FBZ), who has contributed a number of improvements to the original hack and has the wonderful woolens to show for it. We talked about the history of knitting machines, this hack, open hardware and Fabienne’s various projects, and started plotting to make an open source sweater to keep me warm in the winter months. We covered so many different things that I can only show you a brief introduction to her projects now, but there will be more to come!

Brother KH-930 Knitting Machine Hacking and Knitting Tutorial

A video tutorial that was already published 2010 by Becky Stern gives a great overview of the proces to work with a hacked brother knitting machine KH-930e. The hack is based on the work of Steve Conklin and published on github here: https://github.com/adafruit/knitting_machine

The Brother KH-930e Knitting Machine can be controlled by Open Source software. Parts of the process require commandline experience and Python knowledge.

Disk Drive/Computer Connection Notes

The external floppy drive for this machine was the same as a Tandy PDD1 (Portable Disk Drive 1). This drive is connected using a serial port. There is documentation on the internet about how to connect these drives to computers, but the connector pinout on the knitting machine is different than the drive, and I didn't find that documentation to be helpful. I was able to figure out the connector pinout by examining the knitting machine PCB.

Knitting Machine/Computer Connection Notes

The knitting machine drive connection uses CMOS voltage levels, not RS-232. Here is the pinout of the drive connector on the knitting machine:

      _____
      |   |
______|___|______
|   |   |   |   |
| 7 | 5 | 3 | 1 |
|___|___|___|___|
|   |   |   |   |
| 8 | 6 | 4 | 2 |
|___|___|___|___|

The pin numbering is shown as they are labeled on the knitting machine PCB, and does not agree with other documents I found on the web.

Methods of connecting the knitting machine to a computer

Using a FTDI serial adapter cable (RECOMMENDED)

Using an FTDI adapter is the best way to assure that you are interfacing with the machine using the same signal voltages as the original external floppy drives. This is documented on this wiki page, which will someday be merged with this one.MProg only runs under windows.

Using a USB serial adapter WITH flow control

This is a method I have used extensively with one model of knitting machine, but I no longer recommend it. Although it does not require any additional hardware like a FTDI adapter, this method does not present the exact same voltage levels to the knitting machine as the external drives which were designed to work with the machine. Although I have not had any reports of problems, it is possible that this method could stress the knitting machine input circuitry, and therefore I think it is safest not to use it.

Using a USB serial adapter WITHOUT flow control

I have pulled pin 3 high, and am not using flow control in my software. I have not had problems with data loss while sending to the knitting machine, and the machine I am using is fast enough to always keep up with data received from the knitting machine. The data rate is 9600 bps, and the largest amount of data sent at once is 1024 bytes. Here is the cable I am using to connect the knitter with a USB 9 pin serial port:

Software Interface Information

There are a number of documents on the web about the Tandy PDD1 and the serial API for it, Most of them are incomplete. The knitter places the drive into a mode called "FDC emulation Mode", which allows access to raw sectors. This document is the most complete documentation I was able to find: Media:Tandy-Disk-Reference.pdf

External Disk Drive Emulator

I have written software that emulates the external disk. It runs under Linux and keeps the data as files on the linux file system. This allows knitting designs to be saved and restored using the emulation computer. I am using these files to reverse-engineer the knitting machine file format. The emulator is written in Python, and released under the GPL. It has been tested most extensively under Ubuntu Linux. I have reports that it does not work on windows due to problems with the serial library. It has been successfully run under OSX. If you have any information to add about platforms that it does or doesn't work on, let me know and I will update this informationI am happy to work with people who are trying to use the emulator with different models of knitting machine, and hoep to improve compatibility with other machines. The source code is available in the git repository listed above. Software for manipulating Brother data file: I have begun a python class which will provide an API to the brother data files. Source code is in the git repo. Knitting Machine File Format: A lot of the file format is now understood. Documentation is in the git repo.Work on this continues.This work was greatly helped by prior work performed by John R. Hogerhuis and posted on the kminternals yahoo group.

What about Open Source mobile apps

Open Source has been the basis of Android and runs the biggest sites on the net. So what about Open Source apps?

I was looking around for Open Source apps and I found a few sites, that collect them. There is already a short list with apps on Wikipedia. The web catalogue of Android Open Source has about 500 apps to download.

Android Open Source

F-droid, the Android FOSS Repository is an easily-installable catalogue of Free and Open Source software. They have about 750 apps that you can download after you install their catalogue. You can either download the catalogue as an apk from the website, or browse the site to download apps their. You need to have set the ‘allow install from unknown sources’ option on your Android device.

FOSS for Android

Generally areas like office and system apps are already well covered in the Open Source areas. Looking at the popularity of games and gambling there are still many app ideas that can be implemented.
