So it's 15 kilos as well Yeah, there's a bit tricky getting on the plane So we set up an ESP 32 chip Which is listening to a aw s IOT trigger. It's got an onboard Wi-Fi So that blue light is actually telling me that it's having quite an edge to AWS yet So it's just working its way through when the blue light turns off the main that's fine. Yeah, let me tell you about knitting I I took a Domestic knitting machine from the 1980s. We're talking really old-school tech here with a 32-bit Onboard computer and and I hacked it to turn it into a modern-day network printer. So there's a few hacks involved with that one so first of all I used a Raspberry Pi 2 Interface between the onboard computer and my computer so there are three prize obviously sitting on the network and it's running a website Which I can connect to with my laptop and in a completely different room And then I can send it an image and it can process that image Give me a preview of what it'll look like in the knitted fabric and then I can press print and there's there's still a little bit of work involved in actually getting the print started physically with a knitting machine you have to cast on it's There's a bit of a process there, but once it's running I've got a robot arm that's running it backwards and forwards to actually perform the knitting and also built with with the help from my husband John Spencer, I built a An automatic color changer so I can do multiple color meetings. Not just black and white like multicolored netting On this on this old-school knitting machine. Normally they're designed Kind of like a sewing machine in the sense that you sit there and you actively engage with the Machine And you're constantly manipulating it in order to produce The end result which is the Knitting So in the efforts of automating it I took out an entire process of creating knitting patterns So I extra crediting plan. I create an image and then the process will create the pattern for me and then yeah, and I've made the actual color-changing part which which means that I don't need to say with a knitting machine at all once it's running one of my major contributions to the knitting to the Machine knitting community was a whole new algorithm that I created to create one knit per pixel knitting in three colors So that's something that these machines would never previously capable of doing so create a whole new algorithm in order to do that And I think the main reason why no one had done before is because it takes a lot of processing To sort of think through the problem and get it working so I could I was able to create a few different Algorithms and then I you know been the computer scientist I tested lots of different algorithms and I came up with one that cake that had the best results Which is the one you see behind me? Oh there go this pices going off before this piece was actually finished I entered it into something called REA IO, which is a three-day hackathon that my work runs for over three days every quarter Which is amazing And I am yeah, I did a call-out to get help is to light up the constellations Mostly laptop covers scarves Baby blankets. Yes. Oh, I've done it. I've done a few things. Nothing quite this big though So this was a bit intimidating this particular project. I don't know too much about astronomy I'm very much an amateur but I plotted where the planets will line up on the actual knitting's they line up to a particular date and time and I've been working on this project for a few months now So it's kind of hoping that I would hit the deadline and I did actually hit it. This tapestry was installed By or before 6 p.m Friday the 31st which is the day that EMS opened this knitting was installed ready to go and the planets aligned at that time I tell me could you see them always the car? It was actually still daylight But it didn't check that night and it took a few hours later and yeah the the moon was spot on the planets We're pretty much in the right spot sir. Yeah, that was less satisfying No. Oh, right. A few people have asked me that question. I I really want to keep it in the public domain somewhere So I will be taking it home with me. So nothing's really finalized there yet But yeah, hopefully people can actually come and see it and like, you know touch knitting It's it's it's a it's a fabric it, you know people need to touch it. So Hopefully today and public domain somewhere It took a lot longer than I was hoping mostly because I was having a problem with With the yarn getting caught on the left side writing in the color changer. So I mean yarn is a fuzzy fuzzy material
