Those of us who to textile work may own a sewing machine and even if we’re really into it and have the funds, an overlocker. But there’s another machine in that field that few of us will have, and that’s a knitting machine. These machines have a sliding carriage over a long array of needles, and even the cheaper ones are way more expensive than for example a pretty decent oscilloscope. [Irene Wolf] has a Passap E6000 computerised knitting machine that is by no means an inexpensive one, and she’s made significant improvement to it by giving it new brains, a new motor controller, and replacing the mechanical rear needle bed with a set of computerised ones from the front of another machine.

In her write-up she goes in depth into the arrangement of sensors and electromagnets that operate the machine. She started with a lot of inspiration from a project at Hackerspace Bamberg, but used all the available Passap sensors as inputs where they had used only one. She has two Arduino M0 boards handling the inputs and a Raspberry Pi with control and user interface, and has posted some videos of the system in action one of which we’ve placed below the break.

We probably wouldn’t have had the courage to fearlessly hack such a high-value machine, and we’re particularly impressed by the result. The write-up is particularly interesting not only for the work itself, but for the detailed insight it gives to the workings of these machines. The best news – she’s not finished and there will be more installments.

While you’re waiting for more, remember this is by no means the first hacked knitting machine we’ve brought you.
