The Knitting Network Printer (emf2018)

I hacked a domestic knitting machine from the 1980s and turned it into a network printer. I'll show you how I did it using a Raspberry Pi, an Arduino compatible board, Python and a PHP/MySQL web interface. I share my source code. I'll also take you through a brief showcase of what I've done with my printer since automating it, including Stargazing: a knitted tapestry on show for the first time here at EMF! about this event: https://c3voc.de
