AYAB (All Yarns Are Beautiful) is an open-source hardware and software project that replaces the proprietary, aging electronics in vintage Brother KH-9xx series electronic knitting machines. By bypassing the original computer "brains," AYAB allows users to control the needle selection solenoids directly via a modern computer over USB, enabling unlimited pattern repeats and complex photographic imagery.[1]
Functionality
The AYAB interface consists of an Arduino-compatible microcontroller and a specialized "Shield" (hardware board) that connects to the machine’s internal wiring.
- Direct Control: The software sends signals directly to the machine's 8-pin or 16-pin solenoid cables.
- Modern UI: Current development includes porting the desktop frontend to the Valdi framework to improve cross-platform stability and user experience.[2]
- Pattern Support: Supports standard image formats (BMP, PNG) and integrates with tools like AbstractKnitFactoryFactory for garment grading.
Compatibility
AYAB is compatible with most Brother electronic machines, though the hardware shield requirements vary by model:
- Brother KH-910: The most common retrofit; requires the "Shield" to bypass the early proprietary computer.
- Brother KH-930 / 940 / 950i: Supported models that allow for advanced patterning.
- Brother KH-900 / 965: Check specific hardware revisions for compatibility.[3]
Installation
Installation typically involves opening the machine's lid, removing the original logic board, and installing the AYAB shield. This process is non-destructive for many models, allowing the machine to be restored to its original state if desired.
Maintenance and Support
As an open-source project, AYAB is maintained by a global community of developers. Technical tutorials and modernization "hacks" are frequently documented by the KnitFactoryImpl YouTube channel.
