  • Right, so this is a

  • Mission star map of the night sky, it's a it's a little bit big

  • So it's a 2.8 meters tall by four point four meters wide, so

  • It's not a small thing to carry in your luggage on a plane halfway around the world. 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

Right, so this is a
