Limor “Ladyada” Fried and I just finished up a extensive tutorial on hacking the Brother KH-930e knitting machine. We show you how to make your own cable for interfacing with the machine, then how to use it to put custom patterns on the machine without entering them by hand, as I had been doing previously (one excruciating pixel at a time). I made the above tessellating adafruits fabric and the dithering experiment below.
Have questions? Don’t ask them here or send me email, ask in the adafruit forum.
