 The goal of the AYAB project is to provide an alternative way to control the famous Brother KH-9xx knitting machines. The goal of the AYAB project is to provide an alternative way to control the famous Brother KH-9xx knitting machines.

 Der Haupt-Nachteil der existierenden Projekte ist die Verwendung der 930/940er Modeller der Strickmaschine, die immer noch relativ teuer sind. AYAB verwendet das ältere KH-910 Modell. Es ist hauptsächlich wegen seines fehleranfälligen Scanner-Mechanismus zum einlesen der Bilddaten günstiger zu beschaffen (aber AYAB verwendet den Scanner sowieso nicht). Die 930/940er Modelle benutzen bereits eine Art digitaler Programmierung, was andere Möglichkeiten eröffnet sie zu hacken.// Der Haupt-Nachteil der existierenden Projekte ist die Verwendung der 930/940er Modeller der Strickmaschine, die immer noch relativ teuer sind.

 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). Normally, the KH-910 is programmed using semi-transparent picture cards which are scanned by the machine line by line.

 The control of the needles and needed identification of the current position and movement of the knitting carriage is substituted by a common Arduino microntroller, combined with a custom developed shield. You need to open one part of your knitting machine (warranty is void anyway…) and simply substitute the existing control board with the AYAB controller. Connect the Arduino with your computer and start knitting! The control of the needles and needed identification of the current position and movement of the knitting carriage is substituted by a common Arduino microntroller, combined with a custom developed shield.

 The API to the Arduino is designed in a straight forward way, so the control of the machine can be conducted by every piece of software which can access the serial port of your computer (or raspberry pi, or …) The API consists only of three commands (request information about the controller firmware, request the start of a new picture, send line[x] to the controller when the controller requests it). The API to the Arduino is designed in a straight forward way, so the control of the machine can be conducted by every piece of software which can access the serial port of your computer (or raspberry pi, or …) The API consists only of three commands (request information about the controller firmware, request the start of a new picture, send line[x] to the controller when the controller requests it).

 We wanted to hack the cheapest of the KH-9xx knitting machines to open the world of automated knitting to a wide audience. Now take the chance and use AYAB for your own project!
