1 00:00:06,320 --> 00:00:11,499 [Music] 2 00:00:18,480 --> 00:00:25,039 welcome back good afternoon everyone 3 00:00:20,880 --> 00:00:26,800 um we have up now sarah um and 4 00:00:25,039 --> 00:00:28,880 sarah has been a software engineer 5 00:00:26,800 --> 00:00:31,359 professionally working on websites for 6 00:00:28,880 --> 00:00:33,760 the better part of 20 years sarah is no 7 00:00:31,359 --> 00:00:36,960 stranger to talking lca and she last 8 00:00:33,760 --> 00:00:38,960 presented in 2018 she introduced the lca 9 00:00:36,960 --> 00:00:40,559 delegates then to a hacked knitting 10 00:00:38,960 --> 00:00:42,480 network printer 11 00:00:40,559 --> 00:00:44,079 this time she'll be talking to us about 12 00:00:42,480 --> 00:00:46,960 what's been happening since she made her 13 00:00:44,079 --> 00:00:48,960 giant star map of the night sky 14 00:00:46,960 --> 00:00:51,360 sarah's previous lca talks as well as 15 00:00:48,960 --> 00:00:53,039 some links mentioned in her presentation 16 00:00:51,360 --> 00:00:55,840 today are going to be linked in the chat 17 00:00:53,039 --> 00:00:58,559 window so we'll get those too now no my 18 00:00:55,840 --> 00:01:01,120 sarah 19 00:00:58,559 --> 00:01:01,920 amazing thank you so much joel yes the 20 00:01:01,120 --> 00:01:03,920 uh 21 00:01:01,920 --> 00:01:06,479 electrifying the knitted universe let's 22 00:01:03,920 --> 00:01:06,479 get into it 23 00:01:06,560 --> 00:01:09,040 so 24 00:01:07,439 --> 00:01:12,080 i hacked a domestic knitting machine 25 00:01:09,040 --> 00:01:15,280 from the 1980s and turned it into a 26 00:01:12,080 --> 00:01:15,280 network knitting printer 27 00:01:16,159 --> 00:01:19,280 now that's quite a statement all by 28 00:01:17,920 --> 00:01:21,600 itself in north fairness this is 29 00:01:19,280 --> 00:01:23,920 actually the start of my uh presentation 30 00:01:21,600 --> 00:01:27,920 to linux conf australia in the art and 31 00:01:23,920 --> 00:01:29,600 tech mini conf circa 2018 in sydney so 32 00:01:27,920 --> 00:01:31,040 i don't actually have time to talk about 33 00:01:29,600 --> 00:01:32,240 the network knitting printer today 34 00:01:31,040 --> 00:01:33,520 because there's a lot of other stuff for 35 00:01:32,240 --> 00:01:34,799 us to go through 36 00:01:33,520 --> 00:01:36,640 but i did want to give you the link to 37 00:01:34,799 --> 00:01:38,840 it because a few people do find that 38 00:01:36,640 --> 00:01:40,799 quite interesting so the link to it is 39 00:01:38,840 --> 00:01:42,720 tinyurl.com knit printer 40 00:01:40,799 --> 00:01:44,079 and that's a picture of the uh network 41 00:01:42,720 --> 00:01:46,479 meeting printer by itself you can see 42 00:01:44,079 --> 00:01:48,079 there on the left there is a raspberry 43 00:01:46,479 --> 00:01:50,799 pi unit which is doing the network side 44 00:01:48,079 --> 00:01:52,560 of things and a i do it a compatible 45 00:01:50,799 --> 00:01:55,040 custom board which is helping me 46 00:01:52,560 --> 00:01:56,399 automate a few things for me so 47 00:01:55,040 --> 00:01:57,840 the reason why i bring this up is 48 00:01:56,399 --> 00:02:00,079 because 49 00:01:57,840 --> 00:02:03,360 this device allows me to 50 00:02:00,079 --> 00:02:04,479 knit large pieces of fabric 51 00:02:03,360 --> 00:02:07,200 quickly 52 00:02:04,479 --> 00:02:09,119 with few errors and at scale so this is 53 00:02:07,200 --> 00:02:11,680 a capability that i've had for a few 54 00:02:09,119 --> 00:02:13,920 years now um and one of the key points 55 00:02:11,680 --> 00:02:15,680 that came out of this talk was that um 56 00:02:13,920 --> 00:02:18,000 you know what's the point in having 57 00:02:15,680 --> 00:02:20,160 a um 58 00:02:18,000 --> 00:02:22,080 a theme that makes things unless you 59 00:02:20,160 --> 00:02:23,280 actually make something with it right so 60 00:02:22,080 --> 00:02:25,920 i wanted to make something really cool 61 00:02:23,280 --> 00:02:25,920 with this device 62 00:02:26,239 --> 00:02:30,319 so 63 00:02:27,040 --> 00:02:33,840 circa 2018 a few months after linux conf 64 00:02:30,319 --> 00:02:35,360 in sydney uh electromagnetic field uh 65 00:02:33,840 --> 00:02:36,720 festival is coming up so that dramatic 66 00:02:35,360 --> 00:02:38,560 field is kind of confidence under 67 00:02:36,720 --> 00:02:40,000 festival in the sense that uh everyone 68 00:02:38,560 --> 00:02:40,959 comes or all the delegates about a 69 00:02:40,000 --> 00:02:43,519 thousand 70 00:02:40,959 --> 00:02:45,519 five thousand delegates come to a field 71 00:02:43,519 --> 00:02:49,599 to uh to can for a weekend and there's 72 00:02:45,519 --> 00:02:52,319 also talks going on um and uh a lot of 73 00:02:49,599 --> 00:02:53,840 un uh or disorganized uh things going on 74 00:02:52,319 --> 00:02:55,760 as well where lots of hack spaces all 75 00:02:53,840 --> 00:02:57,120 get together and compare notes on 76 00:02:55,760 --> 00:02:59,200 projects and things which is super 77 00:02:57,120 --> 00:03:02,319 exciting um there's some really cool 78 00:02:59,200 --> 00:03:03,680 things that come to emf camp it's uh 79 00:03:02,319 --> 00:03:05,120 for example last time i was there there 80 00:03:03,680 --> 00:03:06,959 was a barbot designed to make strengths 81 00:03:05,120 --> 00:03:09,040 on a conveyor belt uh that was put 82 00:03:06,959 --> 00:03:10,159 together by nottingham hackspace there's 83 00:03:09,040 --> 00:03:11,920 other things like wind powered 84 00:03:10,159 --> 00:03:14,080 landfalling sculptures and hacky soapbox 85 00:03:11,920 --> 00:03:17,599 races so i i think even the last time i 86 00:03:14,080 --> 00:03:19,599 was there i i met matt denton from bb-8 87 00:03:17,599 --> 00:03:21,760 star wars 7 fame and he had a giant 88 00:03:19,599 --> 00:03:22,879 hexapod robot called mantis so these 89 00:03:21,760 --> 00:03:25,280 sort of events are really quite 90 00:03:22,879 --> 00:03:26,640 spectacular and uh it is it is good fun 91 00:03:25,280 --> 00:03:27,440 to go to these 92 00:03:26,640 --> 00:03:31,040 so 93 00:03:27,440 --> 00:03:33,519 i wanted to bring my own project to this 94 00:03:31,040 --> 00:03:35,760 emf camp held in 2018 95 00:03:33,519 --> 00:03:38,159 uh i wanted to make something that would 96 00:03:35,760 --> 00:03:39,040 inspire young minds in in a field of 97 00:03:38,159 --> 00:03:41,519 stem 98 00:03:39,040 --> 00:03:43,120 so um knowing that it would be for an 99 00:03:41,519 --> 00:03:45,440 event that was 100 00:03:43,120 --> 00:03:48,239 camping uh mostly attended by city 101 00:03:45,440 --> 00:03:50,720 dwellers i wanted to showcase a piece of 102 00:03:48,239 --> 00:03:53,120 science that was all around us so i 103 00:03:50,720 --> 00:03:55,760 thought what better way than by showing 104 00:03:53,120 --> 00:03:55,760 them the stars 105 00:03:56,400 --> 00:04:02,159 so that's where this piece was born uh 106 00:03:59,920 --> 00:04:04,159 printed on my network knitting printer 107 00:04:02,159 --> 00:04:05,439 uh as you saw in the photo the network 108 00:04:04,159 --> 00:04:07,519 printer isn't 109 00:04:05,439 --> 00:04:09,519 for me or 110 00:04:07,519 --> 00:04:11,599 4.6 meters wide 111 00:04:09,519 --> 00:04:13,280 i had to knit this in panels and then 112 00:04:11,599 --> 00:04:15,040 stitch them together by hand so you can 113 00:04:13,280 --> 00:04:16,639 see here there's kind of you can kind of 114 00:04:15,040 --> 00:04:17,840 see it in this photo there's like 115 00:04:16,639 --> 00:04:19,280 there's one 116 00:04:17,840 --> 00:04:21,120 one panel there 117 00:04:19,280 --> 00:04:23,440 two 118 00:04:21,120 --> 00:04:26,080 three and in continuum 119 00:04:23,440 --> 00:04:28,240 um and all stitched together so i've 120 00:04:26,080 --> 00:04:29,840 also got here the original source that i 121 00:04:28,240 --> 00:04:32,800 referenced to create the map in the 122 00:04:29,840 --> 00:04:34,560 hoshi for the jp i sourced a japanese 123 00:04:32,800 --> 00:04:35,840 reference largely because they gave me a 124 00:04:34,560 --> 00:04:38,240 creative commons with attribution 125 00:04:35,840 --> 00:04:39,440 license but i did want to stress that 126 00:04:38,240 --> 00:04:40,880 the 127 00:04:39,440 --> 00:04:42,240 vector graphic they gave me was not 128 00:04:40,880 --> 00:04:45,120 something i could actually use with my 129 00:04:42,240 --> 00:04:47,680 kneading printer i had to 130 00:04:45,120 --> 00:04:48,960 hand craft the graphic image 131 00:04:47,680 --> 00:04:51,120 because it had to be really really 132 00:04:48,960 --> 00:04:53,280 specific in order to to work with with 133 00:04:51,120 --> 00:04:55,520 my limitations of knitting so i did have 134 00:04:53,280 --> 00:04:56,960 to recreate that graphic by hand 135 00:04:55,520 --> 00:04:58,479 every one of the stars have a very 136 00:04:56,960 --> 00:05:00,400 specific shape to them based on their 137 00:04:58,479 --> 00:05:01,840 magnification data you can see the 138 00:05:00,400 --> 00:05:04,240 magnifications there down the bottom so 139 00:05:01,840 --> 00:05:06,960 the size of the stars in the map are 140 00:05:04,240 --> 00:05:10,240 relative to their real-life brightness 141 00:05:06,960 --> 00:05:12,720 and only the stars that have a at least 142 00:05:10,240 --> 00:05:14,720 magnification 5 pictured so although 143 00:05:12,720 --> 00:05:15,919 it's a it's a image of the entire milky 144 00:05:14,720 --> 00:05:17,840 way it's only what you can actually 145 00:05:15,919 --> 00:05:19,840 visibly see when you're uh with the 146 00:05:17,840 --> 00:05:22,840 naked eye from earth 147 00:05:19,840 --> 00:05:25,440 so you can see here the uh all 88 148 00:05:22,840 --> 00:05:27,120 constellations uh pictured and 89 149 00:05:25,440 --> 00:05:29,360 constellations are labeled so you can 150 00:05:27,120 --> 00:05:31,199 see here constellation serpens which is 151 00:05:29,360 --> 00:05:32,880 non-contiguous it's actually got the 152 00:05:31,199 --> 00:05:34,639 serpens florida and then the surfans 153 00:05:32,880 --> 00:05:36,720 could put both labeled there which is 154 00:05:34,639 --> 00:05:39,520 why there's 88 officially recognized 155 00:05:36,720 --> 00:05:41,039 constellations but a9 labels 156 00:05:39,520 --> 00:05:42,639 um i also went through and changed a lot 157 00:05:41,039 --> 00:05:45,600 of the lines from the original reference 158 00:05:42,639 --> 00:05:48,400 and uh used my own 159 00:05:45,600 --> 00:05:50,720 font that i created specifically for um 160 00:05:48,400 --> 00:05:52,479 for knitting large pieces 161 00:05:50,720 --> 00:05:54,960 uh i suppose other features you can see 162 00:05:52,479 --> 00:05:56,560 in this are the milky way which is this 163 00:05:54,960 --> 00:05:58,880 this gray 164 00:05:56,560 --> 00:06:02,080 uh cloud through through here and also 165 00:05:58,880 --> 00:06:04,720 the equatorial line or earth's equator 166 00:06:02,080 --> 00:06:06,400 which is uh represented by this 167 00:06:04,720 --> 00:06:08,319 lots of white line is projected out into 168 00:06:06,400 --> 00:06:10,240 space and the reason being that this way 169 00:06:08,319 --> 00:06:12,080 by having earth's equator in the in the 170 00:06:10,240 --> 00:06:14,319 projected in the map you can actually 171 00:06:12,080 --> 00:06:15,680 see what constellations on this on this 172 00:06:14,319 --> 00:06:16,880 particular date and time are falling in 173 00:06:15,680 --> 00:06:18,160 the northern hemisphere versus the 174 00:06:16,880 --> 00:06:20,319 southern hemisphere 175 00:06:18,160 --> 00:06:22,080 and you can tell that it's set to a 176 00:06:20,319 --> 00:06:23,440 particular date and time because we've 177 00:06:22,080 --> 00:06:26,000 got the sun the moon and all of the 178 00:06:23,440 --> 00:06:28,080 planets except for earth pictured 179 00:06:26,000 --> 00:06:31,120 um which is uh gives us a calendar 180 00:06:28,080 --> 00:06:34,479 setting so i figured this out 181 00:06:31,120 --> 00:06:36,160 not long after lca 2018 actually 182 00:06:34,479 --> 00:06:38,560 i worked out exactly what date and time 183 00:06:36,160 --> 00:06:39,919 should be in the star map and that was 184 00:06:38,560 --> 00:06:41,680 from memory 185 00:06:39,919 --> 00:06:44,240 august 186 00:06:41,680 --> 00:06:46,319 31st of august 6 pm uk time which 187 00:06:44,240 --> 00:06:49,120 happened to be the date and time that i 188 00:06:46,319 --> 00:06:50,400 i got to emf browns and i installed the 189 00:06:49,120 --> 00:06:53,680 star map and had it ready for the 190 00:06:50,400 --> 00:06:56,160 opening of the inns festival 191 00:06:53,680 --> 00:06:58,080 so that was really cool 192 00:06:56,160 --> 00:07:00,720 uh so the actual piece wasn't it wasn't 193 00:06:58,080 --> 00:07:02,160 completely entirely finished until i 194 00:07:00,720 --> 00:07:04,479 think the day before i was due to fly 195 00:07:02,160 --> 00:07:05,599 out which is exciting so this photo it 196 00:07:04,479 --> 00:07:07,360 um 197 00:07:05,599 --> 00:07:09,360 i actually put my son down for a nap and 198 00:07:07,360 --> 00:07:10,479 then i unraveled the the star map for 199 00:07:09,360 --> 00:07:12,080 the first time in its entirety and 200 00:07:10,479 --> 00:07:14,240 gotten a quick photo and then 201 00:07:12,080 --> 00:07:15,599 because i was excited i wanted to let my 202 00:07:14,240 --> 00:07:17,599 friends in the uk know i was coming i 203 00:07:15,599 --> 00:07:19,280 sent a tweet out 204 00:07:17,599 --> 00:07:21,360 and it said um 205 00:07:19,280 --> 00:07:23,039 after 15 kilograms of wall and over 100 206 00:07:21,360 --> 00:07:25,120 hours of knitting i'm finally ready to

233 00:08:16,560 --> 00:08:20,080 that actually looked like so this is a 234 00:08:18,479 --> 00:08:22,400 cumulative tweet over time with 235 00:08:20,080 --> 00:08:24,400 followers graph i which i i got a lot of 236 00:08:22,400 --> 00:08:25,599 the data from the twitter api i just 237 00:08:24,400 --> 00:08:26,639 want to graph it and see what was going 238 00:08:25,599 --> 00:08:28,800 on here 239 00:08:26,639 --> 00:08:30,720 uh so this bubble chart showing you over 240 00:08:28,800 --> 00:08:33,599 time just over the first few days the 241 00:08:30,720 --> 00:08:36,240 the arc of the um

each of 248 00:08:44,720 --> 00:08:48,399 those retweeters and quotes uh so you 249 00:08:46,480 --> 00:08:50,240 can get a sense of um you know where all 250 00:08:48,399 --> 00:08:51,519 the big influence was sitting 251 00:08:50,240 --> 00:08:53,279 this isn't every single retweet and 252 00:08:51,519 --> 00:08:54,880 every single quote it's only uh the big 253 00:08:53,279 --> 00:08:55,600 influences so 254 00:08:54,880 --> 00:08:57,279 um 255 00:08:55,600 --> 00:09:00,399 about uh with followers of about ten 256 00:08:57,279 --> 00:09:02,160 thousand plus uh arbitrarily chosen but 257

--> 00:09:54,080 had an image of my star map within the 281 00:09:52,640 --> 00:09:55,519 first few hours of it ever being on the 282 00:09:54,080 --> 00:09:57,040 internet which is just 283 00:09:55,519 --> 00:09:58,959 amazing 284 00:09:57,040 --> 00:10:00,320 um another couple of big bubbles here 285 00:09:58,959 --> 00:10:02,399 we've got mario wilson who is an actress 286 00:10:00,320 --> 00:10:03,760 nandy richard who's a comedian but i did 287 00:10:02,399 --> 00:10:05,440 want to stress that the large majority 288 00:10:03,760 --> 00:10:07,040 of people who are retweeting it and 289 00:10:05,440 --> 00:10:09,680 quoting it were 290 00:10:07,040 --> 00:10:12,160 professors scientists astronomers 291 00:10:09,680 --> 00:10:14,720 mathematicians computer scientists these 292 00:10:12,160 --> 00:10:16,640 are all um people who clearly had 293 00:10:14,720 --> 00:10:19,680 an interest in it on an intellectual 294 00:10:16,640 --> 00:10:21,839 level and i just love that you can have 295 00:10:19,680 --> 00:10:24,480 your professors and scientists and 296 00:10:21,839 --> 00:10:26,720 astronomers um causing something to go 297 00:10:24,480 --> 00:10:28,640 viral for an intellectual basis on in 298 00:10:26,720 --> 00:10:30,480 social media i love that they have that 299 00:10:28,640 --> 00:10:32,800 kind of influence that they can do that 300 00:10:30,480 --> 00:10:35,600 um which is really cool 301 00:10:32,800 --> 00:10:37,600 i thought what i do is very niche 302 00:10:35,600 --> 00:10:40,480 that turns out it appeals to 303 00:10:37,600 --> 00:10:40,480 a lot of people out there 304 00:10:42,480 --> 00:10:47,279 so in the ensuring few weeks quite a few 305 00:10:45,200 --> 00:10:48,480 media outlets did pick it up there was 306 00:10:47,279 --> 00:10:50,640 quite a few articles written about it 307 00:10:48,480 --> 00:10:52,399 that no one no they didn't tell me about 308 00:10:50,640 --> 00:10:54,640 it i i found i found out about a lot of 309 00:10:52,399 --> 00:10:56,399 these accidentally um computer file 310 00:10:54,640 --> 00:10:59,120 hackaday space.com rule and touch when i 311 00:10:56,399 --> 00:11:00,959 was in the field at emf can um compufa 312 00:10:59,120 --> 00:11:04,320 was particularly interesting uh it's 313 00:11:00,959 --> 00:11:05,600 probably one of my most watched talks uh 314 00:11:04,320 --> 00:11:08,079 which also happens to be my worst 315 00:11:05,600 --> 00:11:09,040 performance so when i was at emf camp i 316 00:11:08,079 --> 00:11:10,880 was 317 00:11:09,040 --> 00:11:12,320 horribly jet-lagged i had a nasty flu 318 00:11:10,880 --> 00:11:13,760 and i was sleeping in a borrowed tiny 319 00:11:12,320 --> 00:11:16,079 one-person tent 320 00:11:13,760 --> 00:11:17,760 so i didn't really perform all that well 321 00:11:16,079 --> 00:11:20,399 for that one um 322 00:11:17,760 --> 00:11:22,240 hackaday was good fun i actually uh 323 00:11:20,399 --> 00:11:24,079 hunted down one of the editors jenny 324 00:11:22,240 --> 00:11:24,959 list from hackaday who i knew was at the 325 00:11:24,079 --> 00:11:25,920 event 326 00:11:24,959 --> 00:11:27,279 she was actually minding her own 327 00:11:25,920 --> 00:11:28,720 business in her own tent when i came 328 00:11:27,279 --> 00:11:31,360 knocking and 329 00:11:28,720 --> 00:11:33,839 i thought i had a rough time uh in in 330 00:11:31,360 --> 00:11:35,519 this in this camping situation 331 00:11:33,839 --> 00:11:37,120 her tent was mostly dedicated to a 332 00:11:35,519 --> 00:11:40,480 sewing machine 333 00:11:37,120 --> 00:11:42,000 so i highly respect her priorities 334 00:11:40,480 --> 00:11:44,000 uh physics world and the magpie are both 335 00:11:42,000 --> 00:11:46,720 physical publications so uh it didn't 336 00:11:44,000 --> 00:11:48,240 just uh uh go viral on the internet it 337 00:11:46,720 --> 00:11:50,880 also started to go into print as well 338 00:11:48,240 --> 00:11:52,079 which is amazing make magazine i believe 339 00:11:50,880 --> 00:11:54,240 we're actually talking about the star 340 00:11:52,079 --> 00:11:56,399 map in the next volume volume 80 coming 341 00:11:54,240 --> 00:11:58,399 soon talking about that long tail 342 00:11:56,399 --> 00:11:59,120 um so keep an eye out for that one 343 00:11:58,399 --> 00:12:01,760 that's 344 00:11:59,120 --> 00:12:01,760 pretty amazing 345 00:12:02,320 --> 00:12:06,480 um so a few little pro tips what to 346 00:12:04,240 --> 00:12:08,240 expect me not expecting fame uh twitter 347 00:12:06,480 --> 00:12:09,760 notifications will drive you crazy there 348 00:12:08,240 --> 00:12:11,760 are 349 00:12:09,760 --> 00:12:13,279 100 tens of thousands of likes and and 350 00:12:11,760 --> 00:12:14,880 retweets and quotes and things and you 351 00:12:13,279 --> 00:12:16,320 just got to turn off notifications and i 352 00:12:14,880 --> 00:12:18,320 still to this day i haven't turned them 353 00:12:16,320 --> 00:12:19,519 back on again um 354 00:12:18,320 --> 00:12:20,800 journalists often don't know what 355 00:12:19,519 --> 00:12:23,040 questions to ask particularly when 356 00:12:20,800 --> 00:12:25,360 they're looking at a knitted star map 357 00:12:23,040 --> 00:12:27,519 you know i had to kind of prompt them to 358 00:12:25,360 --> 00:12:29,120 start talking about the network 359 00:12:27,519 --> 00:12:31,040 network knitting printer as well because 360 00:12:29,120 --> 00:12:33,040 that's a big part of how the starmap was 361 00:12:31,040 --> 00:12:34,800 even able to exist 362 00:12:33,040 --> 00:12:36,399 um so i was actually making a press pack 363 00:12:34,800 --> 00:12:38,560 when i was flying to the uk i think i 364 00:12:36,399 --> 00:12:40,160 got a bit of a heads up from the emf uh 365 00:12:38,560 --> 00:12:41,600 camp team to say hey maybe you should 366 00:12:40,160 --> 00:12:43,600 put something together before you land 367 00:12:41,600 --> 00:12:44,959 because that might be important um so 368 00:12:43,600 --> 00:12:46,079 you won't need you won't know you need 369 00:12:44,959 --> 00:12:47,200 to press back until you need to press 370 00:12:46,079 --> 00:12:48,639 back and you'll need to put it all 371 00:12:47,200 --> 00:12:50,079 together fairly quickly 372 00:12:48,639 --> 00:12:51,839 um journalists also on a really tight 373 00:12:50,079 --> 00:12:53,600 deadline so respond quickly to their 374 00:12:51,839 --> 00:12:55,120 requests uh they can be surprisingly 375 00:12:53,600 --> 00:12:56,639 demanding when they and they think that 376 00:12:55,120 --> 00:12:59,279 they're doing your favor 377 00:12:56,639 --> 00:13:01,279 um also you won't get paid uh so have a 378 00:12:59,279 --> 00:13:02,959 think about if someone's asking you for 379 00:13:01,279 --> 00:13:04,639 information or what you're doing for for 380 00:13:02,959 --> 00:13:07,519 publicity reasons have think about what 381 00:13:04,639 --> 00:13:09,040 you want out of it so um at the very at 382 00:13:07,519 --> 00:13:11,920 the very minimum having a link back to 383 00:13:09,040 --> 00:13:13,440 your blog your website or or your 384 00:13:11,920 --> 00:13:15,120 twitter account or anything like that so 385 00:13:13,440 --> 00:13:18,480 that all those eyeballs which 386 00:13:15,120 --> 00:13:19,760 are engaged in in your work uh can um 387 00:13:18,480 --> 00:13:21,279 can reach out to you and follow you 388 00:13:19,760 --> 00:13:22,639 along personally 389 00:13:21,279 --> 00:13:23,920 the long tail i mentioned that it's 390 00:13:22,639 --> 00:13:25,920 still being retweeted today it's still 391 00:13:23,920 --> 00:13:27,760 being commented today um and there's 392 00:13:25,920 --> 00:13:29,360 still articles coming out 393 00:13:27,760 --> 00:13:31,920 uh hundreds of negative comments so 394 00:13:29,360 --> 00:13:34,160 that's an interesting one um 395 00:13:31,920 --> 00:13:36,320 i'd say that the ratio of positive to 396 00:13:34,160 --> 00:13:37,920 negative is prop is approximately 10 so 397 00:13:36,320 --> 00:13:39,360 when something goes viral you'll get 398 00:13:37,920 --> 00:13:41,120 thousands of really positive comments 399 00:13:39,360 --> 00:13:42,720 that also mean an increasing number of 400 00:13:41,120 --> 00:13:44,240 positive comments but also means an 401 00:13:42,720 --> 00:13:46,880 increasing number of negative comments 402 00:13:44,240 --> 00:13:49,199 and there are some real twosies too 403 00:13:46,880 --> 00:13:51,040 um so it can be hard to not just focus 404 00:13:49,199 --> 00:13:53,279 on the hundreds of negative and forget 405 00:13:51,040 --> 00:13:54,720 about the thousands of positive but um i 406 00:13:53,279 --> 00:13:56,480 do think having lots and lots of 407 00:13:54,720 --> 00:13:58,399 negative comments is 408 00:13:56,480 --> 00:14:02,279 perfectly normal and i have learned to 409 00:13:58,399 --> 00:14:02,279 just uh keep on spinning 410 00:14:02,639 --> 00:14:07,519 right so mf camp was amazing there was 411 00:14:04,880 --> 00:14:09,680 an astronomer uh when i was there who uh 412 00:14:07,519 --> 00:14:13,760 did not an impromptu astronomy lesson 413 00:14:09,680 --> 00:14:15,040 with a bunch of uh of students um at emf 414 00:14:13,760 --> 00:14:16,560 camp and i didn't even know about it 415 00:14:15,040 --> 00:14:17,839 like people told me about afterwards i 416 00:14:16,560 --> 00:14:20,399 didn't even know that was gonna happen 417 00:14:17,839 --> 00:14:22,720 or anything so it was amazing uh how 418 00:14:20,399 --> 00:14:24,320 well received the tapestry was uh and 419 00:14:22,720 --> 00:14:26,160 how engaged people were with it so 420 00:14:24,320 --> 00:14:27,360 everything was incredible and um and at 421 00:14:26,160 --> 00:14:28,959 the end of the camp i packed into a 422 00:14:27,360 --> 00:14:31,760 suitcase and brought it back home with 423 00:14:28,959 --> 00:14:32,560 me um 424 00:14:31,760 --> 00:14:34,399 so 425 00:14:32,560 --> 00:14:36,480 the reason why i talk about all the 426 00:14:34,399 --> 00:14:38,320 international publicity is because it 427 00:14:36,480 --> 00:14:40,560 proved one really important thing and 428 00:14:38,320 --> 00:14:42,160 that's the tapestry as a crowd pleaser 429 00:14:40,560 --> 00:14:43,920 uh there's tons of evidence that people 430 00:14:42,160 --> 00:14:45,680 engage with the artwork its story and 431 00:14:43,920 --> 00:14:48,079 wanted to share it with others 432 00:14:45,680 --> 00:14:49,279 um so 433 00:14:48,079 --> 00:14:51,680 after the conference it was just sitting 434 00:14:49,279 --> 00:14:54,000 in a suitcase for a while and i 435 00:14:51,680 --> 00:14:56,079 made it with the intention to inspire 436 00:14:54,000 --> 00:14:58,320 young minds in stem 437 00:14:56,079 --> 00:14:59,360 i had received a few offers of private 438 00:14:58,320 --> 00:15:01,279 sale but 439 00:14:59,360 --> 00:15:02,800 if it goes into some private collection 440 00:15:01,279 --> 00:15:04,240 somewhere i would never be able to go 441 00:15:02,800 --> 00:15:05,519 out and inspire young minds in stem we 442 00:15:04,240 --> 00:15:07,040 wouldn't achieve what it was originally 443 00:15:05,519 --> 00:15:08,320 intended for 444 00:15:07,040 --> 00:15:09,680 um 445 00:15:08,320 --> 00:15:11,360 so i was still trying to work out what i 446 00:15:09,680 --> 00:15:14,079 wanted to do with this exactly or what 447 00:15:11,360 --> 00:15:14,079 to do with the next 448 00:15:15,040 --> 00:15:18,720 so 449 00:15:16,639 --> 00:15:20,720 i made the proposal to donate it to the 450 00:15:18,720 --> 00:15:22,720 state library of victoria an exciting 451 00:15:20,720 --> 00:15:24,480 thing is that when i when i proposed the 452 00:15:22,720 --> 00:15:25,760 donation 453 00:15:24,480 --> 00:15:27,920 they'd actually already heard about it 454 00:15:25,760 --> 00:15:30,240 which is astonishing 455 00:15:27,920 --> 00:15:32,000 um and when i explained that it was made 456 00:15:30,240 --> 00:15:33,920 in melbourne using using locally 457 00:15:32,000 --> 00:15:35,759 resourced materials i actually sourced 458 00:15:33,920 --> 00:15:38,959 all the wool for the tapestry from 459 00:15:35,759 --> 00:15:41,440 bendigo wool and mills um they were 460 00:15:38,959 --> 00:15:44,079 pretty excited and also the fact that 461 00:15:41,440 --> 00:15:46,000 mysteriously magically hardly anyone in 462 00:15:44,079 --> 00:15:47,040 australia has ever actually seen it 463 00:15:46,000 --> 00:15:48,160 so 464 00:15:47,040 --> 00:15:50,320 i asked them if they could make it 465 00:15:48,160 --> 00:15:53,120 available to the general public 466 00:15:50,320 --> 00:15:55,360 and they said they'd get back to me 467 00:15:53,120 --> 00:15:57,120 now this wasn't the tapestries i wasn't 468 00:15:55,360 --> 00:15:59,279 my number one priority at this point i 469 00:15:57,120 --> 00:16:01,920 did actually go on maternity leave um 470 00:15:59,279 --> 00:16:03,839 with my second child so it was quite a 471 00:16:01,920 --> 00:16:05,680 few months there where uh there wasn't a 472 00:16:03,839 --> 00:16:06,800 huge amount of communication 473 00:16:05,680 --> 00:16:10,000 um 474 00:16:06,800 --> 00:16:12,160 but uh astonishingly 475 00:16:10,000 --> 00:16:14,800 uh whilst i was on maternity leave 476 00:16:12,160 --> 00:16:17,519 the state library victoria 477 00:16:14,800 --> 00:16:19,279 uh assembled an exhibition team 478 00:16:17,519 --> 00:16:20,880 with members formed from the curation 479 00:16:19,279 --> 00:16:23,040 and conservation teams 480 00:16:20,880 --> 00:16:27,199 and together they designed an exhibition 481 00:16:23,040 --> 00:16:27,199 with starmap as a centerpiece 482 00:16:27,360 --> 00:16:32,399 which is 483 00:16:28,320 --> 00:16:34,560 astonishing i did not expect anything 484 00:16:32,399 --> 00:16:37,199 like that it is truly amazing 485 00:16:34,560 --> 00:16:38,720 so the exhibition name is 486 00:16:37,199 --> 00:16:40,320 handmade universe 487 00:16:38,720 --> 00:16:42,480 from code to craft 488 00:16:40,320 --> 00:16:43,519 and the spaces between 489 00:16:42,480 --> 00:16:46,639 and it's going to be at the state 490 00:16:43,519 --> 00:16:51,600 library of victoria uh opening sometime 491 00:16:46,639 --> 00:16:53,519 in may 2022 and access will be free 492 00:16:51,600 --> 00:16:55,279 so i believe that the state library 493 00:16:53,519 --> 00:16:58,000 victoria media team haven't actually 494 00:16:55,279 --> 00:16:59,199 made any public announcements yet about 495 00:16:58,000 --> 00:17:02,079 this exhibition although we've been 496 00:16:59,199 --> 00:17:03,839 working on it for a couple of years now 497 00:17:02,079 --> 00:17:05,600 but just like yesterday they gave me 498 00:17:03,839 --> 00:17:06,959 approval to to 499 00:17:05,600 --> 00:17:08,079 to give you more details on it and to 500 00:17:06,959 --> 00:17:09,199 give you the name of the exhibition 501 00:17:08,079 --> 00:17:11,760 which is 502 00:17:09,199 --> 00:17:11,760 amazing 503 00:17:11,839 --> 00:17:14,880 um so that's just got approval for that 504 00:17:13,919 --> 00:17:16,720 late yesterday so you guys are 505 00:17:14,880 --> 00:17:19,039 absolutely the first to hear about this 506 00:17:16,720 --> 00:17:21,480 um so because i haven't been allowed to 507 00:17:19,039 --> 00:17:23,039 talk too much about it i do have 508 00:17:21,480 --> 00:17:24,640 starmapped.harderplug.co so that's just 509 00:17:23,039 --> 00:17:25,520 a landing page with the ability to sign 510 00:17:24,640 --> 00:17:27,679 up to 511 00:17:25,520 --> 00:17:29,440 um just a mailing list and the intent of 512 00:17:27,679 --> 00:17:32,000 that mailing list is just to 513 00:17:29,440 --> 00:17:33,520 i'll just send one message out when um 514 00:17:32,000 --> 00:17:35,440 public comms from the state lab of 515 00:17:33,520 --> 00:17:37,520 victoria go out i'll just you know give 516 00:17:35,440 --> 00:17:39,679 you give you all a link to that and then 517 00:17:37,520 --> 00:17:40,880 also probably one more message on that 518 00:17:39,679 --> 00:17:42,640 mailing list to let you know when the 519 00:17:40,880 --> 00:17:45,120 actual exhibition is open so you can go 520 00:17:42,640 --> 00:17:46,240 along so i do realize that i talk i've 521 00:17:45,120 --> 00:17:48,000 been working on this for such a long 522 00:17:46,240 --> 00:17:49,120 time and a lot of people just say to me 523 00:17:48,000 --> 00:17:50,320 look just just tell me when it's 524 00:17:49,120 --> 00:17:52,559 available tell me when it's raining i'm 525 00:17:50,320 --> 00:17:54,400 like okay we'll just this is this is my 526 00:17:52,559 --> 00:17:55,520 push notifications with this mailing 527 00:17:54,400 --> 00:17:57,360 list to start the mailing list and 528 00:17:55,520 --> 00:17:58,400 there's those notifications if that's 529 00:17:57,360 --> 00:18:01,360 what you want 530 00:17:58,400 --> 00:18:03,200 so that's available to you 531 00:18:01,360 --> 00:18:05,120 um so more about the exhibition there 532 00:18:03,200 --> 00:18:07,440 are four key themes we've got 533 00:18:05,120 --> 00:18:09,120 crafting coding astronomy and mapping 534 00:18:07,440 --> 00:18:10,960 those the key things which are coming 535 00:18:09,120 --> 00:18:11,760 out of the star map itself 536 00:18:10,960 --> 00:18:12,880 um 537 00:18:11,760 --> 00:18:15,360 really 538 00:18:12,880 --> 00:18:17,120 beautiful artworks owned by other 539 00:18:15,360 --> 00:18:18,559 institutions across victoria will also 540 00:18:17,120 --> 00:18:20,880 be featured in the exhibition along with 541 00:18:18,559 --> 00:18:23,039 the starmap and incredibly new artworks 542 00:18:20,880 --> 00:18:25,039 we have been commissioned specifically 543 00:18:23,039 --> 00:18:27,760 for this expert exhibition 544 00:18:25,039 --> 00:18:29,760 so the startup has been creating new 545 00:18:27,760 --> 00:18:32,160 opportunities for artists across 546 00:18:29,760 --> 00:18:34,080 victoria which is 547 00:18:32,160 --> 00:18:35,760 amazing 548 00:18:34,080 --> 00:18:37,760 i i don't have words to describe how 549 00:18:35,760 --> 00:18:40,760 incredibly grateful i am for this 550 00:18:37,760 --> 00:18:40,760 opportunity 551 00:18:42,400 --> 00:18:45,280 in addition to all the other 552 00:18:44,000 --> 00:18:47,520 opportunities which are going on at the 553 00:18:45,280 --> 00:18:50,720 same time the exhibition team also gave 554 00:18:47,520 --> 00:18:52,080 me the opportunity to finish the startup 555 00:18:50,720 --> 00:18:53,280 and by finish it 556 00:18:52,080 --> 00:18:55,520 i mean 557 00:18:53,280 --> 00:18:57,520 i'd always intended to light up every 558 00:18:55,520 --> 00:19:00,080 significant star and celestial body in 559 00:18:57,520 --> 00:19:01,760 the tapestry 560 00:19:00,080 --> 00:19:03,760 the piece was intended to inspire young 561 00:19:01,760 --> 00:19:05,120 minds of stem it was never meant to just 562 00:19:03,760 --> 00:19:06,880 be an artwork it was meant to be an 563 00:19:05,120 --> 00:19:09,679 interactive experience and blow the 564 00:19:06,880 --> 00:19:10,799 boundaries between art and science 565 00:19:09,679 --> 00:19:13,120 so 566 00:19:10,799 --> 00:19:15,360 um for emf camp um i actually had the 567 00:19:13,120 --> 00:19:18,160 help of an amazing team at ra group 568 00:19:15,360 --> 00:19:20,720 hackathon where we managed to use aws 569 00:19:18,160 --> 00:19:23,039 and an esp32 microcontroller to light up 570 00:19:20,720 --> 00:19:24,960 just eight of the 88 constellations in 571 00:19:23,039 --> 00:19:26,799 the zodiac and that was very cool and i 572 00:19:24,960 --> 00:19:29,200 was working at emf camp 573 00:19:26,799 --> 00:19:30,640 but now in preparation for an exhibition 574 00:19:29,200 --> 00:19:33,520 and particularly with a conservation 575 00:19:30,640 --> 00:19:35,840 team on board who are wanting to 576 00:19:33,520 --> 00:19:37,760 preserve the work for 100 years 577 00:19:35,840 --> 00:19:39,039 i had to completely reimagine how these 578 00:19:37,760 --> 00:19:41,520 electronics were actually going to 579 00:19:39,039 --> 00:19:44,160 function and also 580 00:19:41,520 --> 00:19:47,360 be preserved for the long term so 581 00:19:44,160 --> 00:19:50,320 circa 2020 two years and one child after 582 00:19:47,360 --> 00:19:53,840 going viral i embarked on a whole new 583 00:19:50,320 --> 00:19:53,840 journey into electronics 584 00:19:55,760 --> 00:19:58,960 so this is the prototype i had to get 585 00:19:57,280 --> 00:20:00,640 sign off from from the conservation team 586 00:19:58,960 --> 00:20:01,840 on materials 587 00:20:00,640 --> 00:20:03,760 so it was really handy having a 588 00:20:01,840 --> 00:20:04,960 prototype as a proof of concept showing 589 00:20:03,760 --> 00:20:07,039 how it's going to be assembled and how 590 00:20:04,960 --> 00:20:09,039 it's actually going to work 591 00:20:07,039 --> 00:20:11,200 so you can see here a sample of the 592 00:20:09,039 --> 00:20:12,960 initial 593 00:20:11,200 --> 00:20:14,960 knitted layer so it's actually got a 594 00:20:12,960 --> 00:20:16,960 seam running through it as well there as 595 00:20:14,960 --> 00:20:19,200 i mentioned there are seven panels so 596 00:20:16,960 --> 00:20:21,600 six seams in the work so 597 00:20:19,200 --> 00:20:24,080 understanding how the led layer will 598 00:20:21,600 --> 00:20:26,400 work with um with the 599 00:20:24,080 --> 00:20:27,440 the seams in the in the in the tapestry 600 00:20:26,400 --> 00:20:31,760 was really important so that's why 601 00:20:27,440 --> 00:20:31,760 there's a scene in the prototype as well 602 00:20:31,919 --> 00:20:37,440 so directly underneath that knitted 603 00:20:34,240 --> 00:20:41,200 layer we have here a really simple um 604 00:20:37,440 --> 00:20:42,080 piece of uh 100 uh museum quality cotton 605 00:20:41,200 --> 00:20:43,360 and 606 00:20:42,080 --> 00:20:45,360 you can see that there are the 607 00:20:43,360 --> 00:20:47,520 constellations drawn on the cotton 608 00:20:45,360 --> 00:20:49,919 underneath the knitted layer and zooming 609 00:20:47,520 --> 00:20:51,039 in now we can see so all the electronics 610 00:20:49,919 --> 00:20:55,039 are actually sitting in the back of the 611 00:20:51,039 --> 00:20:57,200 work we have eyelets which is uh 612 00:20:55,039 --> 00:20:58,720 allowing the light from the leds in the 613 00:20:57,200 --> 00:20:59,840 back of the work to actually shine 614 00:20:58,720 --> 00:21:01,600 through 615 00:20:59,840 --> 00:21:04,640 and the eyelets are protecting the open 616 00:21:01,600 --> 00:21:06,240 holes in the in the cotton fabric 617 00:21:04,640 --> 00:21:07,840 um so the 618 00:21:06,240 --> 00:21:10,320 through these arts you can see some 619 00:21:07,840 --> 00:21:12,159 acrylic light wells so the light well is 620 00:21:10,320 --> 00:21:14,559 what's actually channeling the light 621 00:21:12,159 --> 00:21:16,320 from the leds in the back and poking 622 00:21:14,559 --> 00:21:18,000 through the knitting so that we've got a 623 00:21:16,320 --> 00:21:19,440 really strong pink prick of light 624 00:21:18,000 --> 00:21:23,280 through the knitting even though the led 625 00:21:19,440 --> 00:21:23,280 is actually a couple of layers beneath 626 00:21:23,360 --> 00:21:27,600 um you can also see that the seams in 627 00:21:25,360 --> 00:21:29,039 the backing fabric correspond to the 628 00:21:27,600 --> 00:21:31,440 seams in the 629 00:21:29,039 --> 00:21:33,360 knitted layer and the reason being that 630 00:21:31,440 --> 00:21:35,840 um in the when i produced the original 631 00:21:33,360 --> 00:21:38,559 knitted layer i actually um 632 00:21:35,840 --> 00:21:40,080 moved the stars ever so slightly either 633 00:21:38,559 --> 00:21:41,120 left or right of those seams because i 634 00:21:40,080 --> 00:21:42,559 didn't want to start sitting directly on 635 00:21:41,120 --> 00:21:44,400 the scene which means that in the 636 00:21:42,559 --> 00:21:46,880 backing fabric i can have these same 637 00:21:44,400 --> 00:21:50,320 seams and know that there won't be any 638 00:21:46,880 --> 00:21:50,320 leds sitting directly on the scene 639 00:21:50,400 --> 00:21:55,120 so here it looks like this is what it 640 00:21:51,840 --> 00:21:55,120 looks like at the back we've got 641 00:21:55,679 --> 00:21:59,919 neopixels each one of them having uh 642 00:21:58,400 --> 00:22:02,880 three three pins going in three things 643 00:21:59,919 --> 00:22:05,120 going out so it's a five volt data and 644 00:22:02,880 --> 00:22:07,440 ground going in and then five volt data 645 00:22:05,120 --> 00:22:09,760 and ground going out to create a string 646 00:22:07,440 --> 00:22:11,120 of leds and on each panel we have a 647 00:22:09,760 --> 00:22:12,720 separate string 648 00:22:11,120 --> 00:22:15,120 the reason being we don't want a single 649 00:22:12,720 --> 00:22:17,280 point of failure for this electronics um 650 00:22:15,120 --> 00:22:19,520 no one no one point of value should be 651 00:22:17,280 --> 00:22:22,080 able to take out all of the leds at one 652 00:22:19,520 --> 00:22:26,080 time so each patch so seven panels so 653 00:22:22,080 --> 00:22:27,840 seven uh strings of leds 654 00:22:26,080 --> 00:22:29,520 and those leds are actually glued 655 00:22:27,840 --> 00:22:32,400 directly onto the 656 00:22:29,520 --> 00:22:32,400 uh um 657 00:22:32,720 --> 00:22:39,039 uh the um the eyelets so and that's that 658 00:22:36,480 --> 00:22:40,400 glue is uh is just um like super glue 659 00:22:39,039 --> 00:22:42,240 reason being that superglue is very 660 00:22:40,400 --> 00:22:44,799 strong but it's also incredibly brittle 661 00:22:42,240 --> 00:22:46,559 so if an led fails or a bunch of leds 662 00:22:44,799 --> 00:22:48,400 fail during the exhibition then i can 663 00:22:46,559 --> 00:22:51,039 actually go in and replace them by using 664 00:22:48,400 --> 00:22:53,120 a sheer force um uh 665 00:22:51,039 --> 00:22:55,360 against the um 666 00:22:53,120 --> 00:22:58,400 the led and 667 00:22:55,360 --> 00:23:00,400 it should actually cause the um 668 00:22:58,400 --> 00:23:02,320 the glue to break and that will enable 669 00:23:00,400 --> 00:23:04,000 me to disalter the led and just quickly 670 00:23:02,320 --> 00:23:05,760 hot swap and replace it without too much 671 00:23:04,000 --> 00:23:07,280 work 672 00:23:05,760 --> 00:23:08,640 uh so i did have a few discussions with 673 00:23:07,280 --> 00:23:11,520 the conservation team around the 674 00:23:08,640 --> 00:23:13,679 ordering of lighting up these leds and 675 00:23:11,520 --> 00:23:15,760 uh their original thinking was that i i 676 00:23:13,679 --> 00:23:17,840 would um that the string of leds would 677 00:23:15,760 --> 00:23:19,840 be in order of we are what appears in 678 00:23:17,840 --> 00:23:20,960 each constellation but i stress to them 679 00:23:19,840 --> 00:23:24,240 that i want to choose this traveling 680 00:23:20,960 --> 00:23:27,440 salesman problem and that is minimum 681 00:23:24,240 --> 00:23:29,760 minimum number of um or minimum or 682 00:23:27,440 --> 00:23:31,200 creating the shortest distance 683 00:23:29,760 --> 00:23:33,600 for every destination still getting to 684 00:23:31,200 --> 00:23:34,880 every single destination so that means 685 00:23:33,600 --> 00:23:36,960 we use the 686 00:23:34,880 --> 00:23:38,880 minimum amount of wiring to still 687 00:23:36,960 --> 00:23:40,799 achieve the same effect where none of 688 00:23:38,880 --> 00:23:42,720 the wiring actually crosses over over 689 00:23:40,799 --> 00:23:44,320 another piece of wiring um given the 690 00:23:42,720 --> 00:23:46,400 scale of this thing the weight of the 691 00:23:44,320 --> 00:23:47,919 wiring was a consideration so 692 00:23:46,400 --> 00:23:49,679 we didn't really need to use as little 693 00:23:47,919 --> 00:23:51,600 wiring as possible hence the travelling 694 00:23:49,679 --> 00:23:54,960 salesman problem and i will come back to 695 00:23:51,600 --> 00:23:57,200 that in in just a little bit 696 00:23:54,960 --> 00:23:59,919 um so a couple of other things so we're 697 00:23:57,200 --> 00:24:02,159 also using pigment ink formulation pens 698 00:23:59,919 --> 00:24:03,520 uh for preservation purposes they 699 00:24:02,159 --> 00:24:05,840 shouldn't fade quite so much over time 700 00:24:03,520 --> 00:24:07,520 low odor glue 701 00:24:05,840 --> 00:24:09,520 overlocker to protect the raw edges so 702 00:24:07,520 --> 00:24:11,120 you can see that uh the the raw edges 703 00:24:09,520 --> 00:24:13,440 have been overlocked 704 00:24:11,120 --> 00:24:15,200 uh lead-free solder and also lead-free 705 00:24:13,440 --> 00:24:16,960 immersion gold finish on the circuit 706 00:24:15,200 --> 00:24:18,720 board which is less toxic and also more 707 00:24:16,960 --> 00:24:20,400 reliable in the long run so lots of 708 00:24:18,720 --> 00:24:22,159 considerations and that was all signed 709 00:24:20,400 --> 00:24:24,320 off by conservation 710 00:24:22,159 --> 00:24:25,600 which meant i could work on the real 711 00:24:24,320 --> 00:24:26,799 thing so 712 00:24:25,600 --> 00:24:28,240 um 713 00:24:26,799 --> 00:24:29,600 you would think that 714 00:24:28,240 --> 00:24:31,200 creating each panel complete 715 00:24:29,600 --> 00:24:32,559 individually and then assembling it 716 00:24:31,200 --> 00:24:33,919 together at the end would be the most 717 00:24:32,559 --> 00:24:35,679 efficient 718 00:24:33,919 --> 00:24:37,200 or the easiest way to do things but i 719 00:24:35,679 --> 00:24:39,679 actually found that 720 00:24:37,200 --> 00:24:41,200 i needed to sew everything together up 721 00:24:39,679 --> 00:24:43,120 front largely because in the middle of a 722 00:24:41,200 --> 00:24:45,039 pandemic i've only got 723 00:24:43,120 --> 00:24:47,520 domestic equipment available to me at 724 00:24:45,039 --> 00:24:48,799 any one time so i there's no if i had 725 00:24:47,520 --> 00:24:50,240 done all the soldering first and then 726 00:24:48,799 --> 00:24:51,679 stitched it all together later there's 727 00:24:50,240 --> 00:24:54,240 no way i could have actually fit all of 728 00:24:51,679 --> 00:24:56,400 that soldering um particularly when i 729 00:24:54,240 --> 00:24:58,400 was using a very brittle glue uh to 730 00:24:56,400 --> 00:24:59,679 actually fit it through a sewing machine 731 00:24:58,400 --> 00:25:01,600 and an overlocker as well there just 732 00:24:59,679 --> 00:25:03,919 wasn't enough space so i really did need 733 00:25:01,600 --> 00:25:06,159 to just create the entire backing fabric 734 00:25:03,919 --> 00:25:07,840 in one large piece and then work on it 735 00:25:06,159 --> 00:25:09,200 from there 736 00:25:07,840 --> 00:25:10,960 so that's that's an overlocker 737 00:25:09,200 --> 00:25:14,279 especially when i found it upshot for 15 738 00:25:10,960 --> 00:25:14,279 which is great 739 00:25:15,679 --> 00:25:20,240 all right so here we have the entire 740 00:25:18,320 --> 00:25:22,559 backing fabric laid out on my living 741 00:25:20,240 --> 00:25:24,080 room floor this piece has been taking my 742 00:25:22,559 --> 00:25:25,760 entire living room now for several 743 00:25:24,080 --> 00:25:28,480 months so that's that's been that's been 744 00:25:25,760 --> 00:25:31,440 delightful um so the the next challenge 745 00:25:28,480 --> 00:25:32,159 was how do i get that um the image of 746 00:25:31,440 --> 00:25:35,840 the 747 00:25:32,159 --> 00:25:38,480 tapestry uh onto the backing fabric uh 748 00:25:35,840 --> 00:25:41,279 so i found that the solution here was 749 00:25:38,480 --> 00:25:42,720 definitely a lot of pins so laying the 750 00:25:41,279 --> 00:25:44,720 backing fabric out and stretching as 751 00:25:42,720 --> 00:25:46,960 tight as i could lots of pins to pin it 752 00:25:44,720 --> 00:25:48,640 down laying the knitted fabric on top as 753 00:25:46,960 --> 00:25:50,799 well and painting that down really 754 00:25:48,640 --> 00:25:52,799 strategically i then used lots and lots 755 00:25:50,799 --> 00:25:55,679 of pins i think in total i end up 756 00:25:52,799 --> 00:25:56,480 using like 500 pins at any one time 757 00:25:55,679 --> 00:25:58,080 and 758 00:25:56,480 --> 00:26:00,080 i did actually go back and catalogue 759 00:25:58,080 --> 00:26:01,279 every single star and celestial body 760 00:26:00,080 --> 00:26:03,919 that i wanted to light up in this piece 761 00:26:01,279 --> 00:26:05,679 so not every star that's pictured has 762 00:26:03,919 --> 00:26:07,840 a light attached to it really depends on 763 00:26:05,679 --> 00:26:09,679 the magnification of those stars and how 764 00:26:07,840 --> 00:26:12,240 significant they were i think total 765 00:26:09,679 --> 00:26:14,480 ended up being uh 840 766 00:26:12,240 --> 00:26:17,600 uh leds in the piece 767 00:26:14,480 --> 00:26:17,600 so definitely lots of pinning 768 00:26:18,000 --> 00:26:20,960 and it was quite back breaking labor too 769 00:26:19,679 --> 00:26:22,240 like this is this is a hell of a lot of 770 00:26:20,960 --> 00:26:23,600 work and this is like 771 00:26:22,240 --> 00:26:25,760 i think a couple of weeks of just 772 00:26:23,600 --> 00:26:28,159 pinning and and you know bending over 773 00:26:25,760 --> 00:26:29,760 this giant tapestry trying to get 840 774 00:26:28,159 --> 00:26:31,360 points as accurate as i possibly could 775 00:26:29,760 --> 00:26:33,279 so it was a lot of work and i'm really 776 00:26:31,360 --> 00:26:35,679 glad that's over 777 00:26:33,279 --> 00:26:37,919 and you can see there is um how that's 778 00:26:35,679 --> 00:26:39,840 starting to look uh in the backing 779 00:26:37,919 --> 00:26:41,600 fabric now i know that the backing 780 00:26:39,840 --> 00:26:43,760 fabric is never intended to actually be 781 00:26:41,600 --> 00:26:45,200 seen by the general public but i was 782 00:26:43,760 --> 00:26:47,200 really conscious that this thing's going 783 00:26:45,200 --> 00:26:49,279 to be preserved for the long term so i 784 00:26:47,200 --> 00:26:53,120 did want to make it as neat and nice as 785 00:26:49,279 --> 00:26:55,600 neat and nice as i possibly could 786 00:26:53,120 --> 00:26:58,400 right so the next step how do i get the 787 00:26:55,600 --> 00:27:00,080 uh that image that i've uh translated 788 00:26:58,400 --> 00:27:01,279 from the knitted layer to the front of 789 00:27:00,080 --> 00:27:02,720 the backing paper how do i get from the 790 00:27:01,279 --> 00:27:04,640 front of the backing fabric to the back 791 00:27:02,720 --> 00:27:07,360 of the backing fabric this is one huge 792 00:27:04,640 --> 00:27:09,840 piece of fabric it's it's it's over four 793 00:27:07,360 --> 00:27:11,279 meters wide about and three meters tall 794 00:27:09,840 --> 00:27:14,080 uh so 795 00:27:11,279 --> 00:27:15,679 flipping over continuously for 840 796 00:27:14,080 --> 00:27:18,399 points and and then you know drawing all 797 00:27:15,679 --> 00:27:21,520 the lines as well uh it was way way too 798 00:27:18,399 --> 00:27:22,720 much work for for my taste so i 799 00:27:21,520 --> 00:27:25,200 i'm a little bit embarrassed by the 800 00:27:22,720 --> 00:27:26,960 solution and yeah it is what it is but i 801 00:27:25,200 --> 00:27:29,039 ended up just uh 802 00:27:26,960 --> 00:27:30,480 using a makeshift table so this table is 803 00:27:29,039 --> 00:27:32,960 just basically a piece of mdf which is 804 00:27:30,480 --> 00:27:35,360 three meters long and and sitting 805 00:27:32,960 --> 00:27:38,559 underneath the table with the um 806 00:27:35,360 --> 00:27:39,840 with the fabric uh hanging over the edge 807 00:27:38,559 --> 00:27:41,360 it meant that 808 00:27:39,840 --> 00:27:42,640 uh running pins through it i actually 809 00:27:41,360 --> 00:27:44,480 had access to both the front and the 810 00:27:42,640 --> 00:27:46,159 back of the fabric so i could you know 811 00:27:44,480 --> 00:27:48,159 sneak in underneath double check all of 812 00:27:46,159 --> 00:27:50,480 my my stars that i wanted to light up 813 00:27:48,159 --> 00:27:51,760 run pins through and then sneak out out 814 00:27:50,480 --> 00:27:52,640 from underneath the table go around the 815 00:27:51,760 --> 00:27:54,960 other side and actually do all the 816 00:27:52,640 --> 00:27:56,960 drawing onto the fabric and then once 817 00:27:54,960 --> 00:27:59,120 all that was done i dragged onto the 818 00:27:56,960 --> 00:28:00,240 floor and then i put in all of those 819 00:27:59,120 --> 00:28:03,679 light and 820 00:28:00,240 --> 00:28:04,960 those eyelets as well 821 00:28:03,679 --> 00:28:06,480 so 822 00:28:04,960 --> 00:28:07,679 a little bit awkward very strange i had 823 00:28:06,480 --> 00:28:10,159 my own little cubby house my kids are 824 00:28:07,679 --> 00:28:11,679 very jealous 825 00:28:10,159 --> 00:28:14,240 all right so that's that's all of it 826 00:28:11,679 --> 00:28:15,760 that's um the backing fabric with both 827 00:28:14,240 --> 00:28:17,919 labels on the front labels on the back 828 00:28:15,760 --> 00:28:19,600 and also all those eyelets have been 829 00:28:17,919 --> 00:28:22,640 punched there's a lot of hammering and 830 00:28:19,600 --> 00:28:22,640 very good with a hammer there 831 00:28:22,960 --> 00:28:26,559 right now so what we're up to is the 832 00:28:24,960 --> 00:28:29,440 allergies themselves so coming back to 833 00:28:26,559 --> 00:28:32,399 that travelling salesman problem 834 00:28:29,440 --> 00:28:34,000 um so travelling salesman is an mp hard 835 00:28:32,399 --> 00:28:35,679 problem and i'd love to tell you that i 836 00:28:34,000 --> 00:28:38,880 solved an np hard problem as part of 837 00:28:35,679 --> 00:28:40,559 this project but i absolutely did not so 838 00:28:38,880 --> 00:28:43,360 the tricky thing with an mp hard problem 839 00:28:40,559 --> 00:28:45,039 is that it becomes more computationally 840 00:28:43,360 --> 00:28:48,320 expensive for every point that you add 841 00:28:45,039 --> 00:28:49,600 exponentially so um a lot of solutions 842 00:28:48,320 --> 00:28:51,600 to the travel salesman problem works 843 00:28:49,600 --> 00:28:53,600 perfectly well for 30 or 40 points but 844 00:28:51,600 --> 00:28:56,720 for my uh i think the worst panel was 845 00:28:53,600 --> 00:28:58,320 panel six with 140 points that was uh 846 00:28:56,720 --> 00:29:00,159 well and truly beyond uh the 847 00:28:58,320 --> 00:29:02,240 capabilities of a lot of solutions i was 848 00:29:00,159 --> 00:29:04,080 looking at so uh you can see here the 849 00:29:02,240 --> 00:29:06,000 links to the open processing uh so i did 850 00:29:04,080 --> 00:29:07,760 use open processing because i was uh 851 00:29:06,000 --> 00:29:10,640 translating it from a bitmap image which 852 00:29:07,760 --> 00:29:12,799 is where all my stars were located uh to 853 00:29:10,640 --> 00:29:15,200 uh in order to draw between all of those 854 00:29:12,799 --> 00:29:16,559 individual points and and work out the 855 00:29:15,200 --> 00:29:18,000 the shortest instance because i was 856 00:29:16,559 --> 00:29:20,159 working from the bitmap 857 00:29:18,000 --> 00:29:21,600 um and open processing is really really 858 00:29:20,159 --> 00:29:23,840 good with images and bitmaps so that's 859 00:29:21,600 --> 00:29:25,039 why i used it so the actual code in 860 00:29:23,840 --> 00:29:27,840 there you can have a look at it i think 861 00:29:25,039 --> 00:29:29,520 it's just got um half of panel five uh 862 00:29:27,840 --> 00:29:31,039 currently pictured so you can you can 863 00:29:29,520 --> 00:29:33,360 have play around with that it's a 864 00:29:31,039 --> 00:29:35,440 evolutionary algorithm uh that is 865 00:29:33,360 --> 00:29:37,120 optimizing uh the roots for every 866 00:29:35,440 --> 00:29:38,640 generation so it passes through lots of 867 00:29:37,120 --> 00:29:40,399 generations and for each generation 868 00:29:38,640 --> 00:29:41,360 where it's found a more optimum route 869 00:29:40,399 --> 00:29:42,640 then it will 870 00:29:41,360 --> 00:29:45,919 adjust the um 871 00:29:42,640 --> 00:29:45,919 adjust the the word accordingly 872 00:29:46,799 --> 00:29:50,880 so once we have uh the traveling 873 00:29:49,200 --> 00:29:52,320 salesman solutions i then went into 874 00:29:50,880 --> 00:29:53,200 soldering mode 875 00:29:52,320 --> 00:29:56,559 um 876 00:29:53,200 --> 00:29:58,080 so it's uh i was no longer working on 877 00:29:56,559 --> 00:29:59,919 the floor anymore which is really nice 878 00:29:58,080 --> 00:30:03,039 no longer on the floor i was not at the 879 00:29:59,919 --> 00:30:05,200 desk um the desk was just the right 880 00:30:03,039 --> 00:30:07,200 length for the entire tapestry and and 881 00:30:05,200 --> 00:30:08,880 one panel at a time so i did work one 882 00:30:07,200 --> 00:30:10,559 panel at a time and then once i'd done 883 00:30:08,880 --> 00:30:12,960 all the soldering on a per panel basis i 884 00:30:10,559 --> 00:30:13,919 then dragged it over the desk in this 885 00:30:12,960 --> 00:30:15,039 picture the 886 00:30:13,919 --> 00:30:16,480 the rest of the tapestry is actually 887 00:30:15,039 --> 00:30:18,000 sitting underneath the desk all folded 888 00:30:16,480 --> 00:30:20,799 up so i just dragged it over the desk 889 00:30:18,000 --> 00:30:23,279 and the the um 890 00:30:20,799 --> 00:30:25,440 the soldered points were slowly being uh 891 00:30:23,279 --> 00:30:27,679 draped down one side and then onto the 892 00:30:25,440 --> 00:30:27,679 floor 893 00:30:28,720 --> 00:30:32,320 uh one thing i didn't account for in the 894 00:30:30,559 --> 00:30:33,919 traveling salesman problem that i i did 895 00:30:32,320 --> 00:30:36,799 was uh the curvature of the of the 896 00:30:33,919 --> 00:30:38,799 cabling so because the direction of of 897 00:30:36,799 --> 00:30:41,919 all six pins are very specific the 898 00:30:38,799 --> 00:30:44,799 cabling also uh had had to have certain 899 00:30:41,919 --> 00:30:46,720 curvature to it so the solution when 900 00:30:44,799 --> 00:30:48,240 there is no curvature to the cabling 901 00:30:46,720 --> 00:30:50,000 isn't necessarily the optimal solution 902 00:30:48,240 --> 00:30:51,919 for when there is and that's just a side 903 00:30:50,000 --> 00:30:53,440 effect of you know by the time i started 904 00:30:51,919 --> 00:30:55,080 start soldering at this point i'm like 905 00:30:53,440 --> 00:30:57,360 i'm not going to go back and try and 906 00:30:55,080 --> 00:30:59,120 recalculate out all of the the optimal 907 00:30:57,360 --> 00:31:03,159 points when what we had was or was 908 00:30:59,120 --> 00:31:03,159 already pretty good 909 00:31:04,960 --> 00:31:07,440 right 910 00:31:05,840 --> 00:31:09,919 uh in this photo i'm actually watching a 911 00:31:07,440 --> 00:31:12,720 live stream by jonathan oxford and i'm 912 00:31:09,919 --> 00:31:14,960 going to misquote johnocza here um 913 00:31:12,720 --> 00:31:17,440 he's he likes to say that making 50 of 914 00:31:14,960 --> 00:31:18,480 something is repetitive of despair 915 00:31:17,440 --> 00:31:20,320 so 916 00:31:18,480 --> 00:31:23,120 you can just imagine where i was with 917 00:31:20,320 --> 00:31:24,960 840 leds to solder stuck at home with 918 00:31:23,120 --> 00:31:26,880 two preschool kids 919 00:31:24,960 --> 00:31:28,399 in the middle of a lockdown unable to 920 00:31:26,880 --> 00:31:31,440 call and help 921 00:31:28,399 --> 00:31:33,440 um i had provisioned and i i had it you 922 00:31:31,440 --> 00:31:35,039 know planned for all of this knowing 923 00:31:33,440 --> 00:31:37,840 that there was a pandemic in place but 924 00:31:35,039 --> 00:31:39,360 at this point in uh 2021 i had i 925 00:31:37,840 --> 00:31:40,799 genuinely thought the long lockdowns 926 00:31:39,360 --> 00:31:42,720 were over and that daycare wouldn't 927 00:31:40,799 --> 00:31:44,480 close again i genuinely thought at this 928 00:31:42,720 --> 00:31:46,399 point that the short snap lockdowns 929 00:31:44,480 --> 00:31:48,799 would be effective so when we did go 930 00:31:46,399 --> 00:31:50,240 back into a long lockdown um 931 00:31:48,799 --> 00:31:51,440 i had a huge amount of work and i 932 00:31:50,240 --> 00:31:53,200 couldn't actually work on it for the 933 00:31:51,440 --> 00:31:54,799 non-parents out there um it's not 934 00:31:53,200 --> 00:31:56,640 possible to or you can't actually keep 935 00:31:54,799 --> 00:31:57,760 young children safe and sold their 936 00:31:56,640 --> 00:31:59,279 electronics at the same time 937 00:31:57,760 --> 00:32:00,960 particularly when those electronics are 938 00:31:59,279 --> 00:32:02,399 filling an entire room so that was 939 00:32:00,960 --> 00:32:05,039 definitely a challenge 940 00:32:02,399 --> 00:32:06,159 um i'm still not entirely sure how we 941 00:32:05,039 --> 00:32:07,519 got through it 942 00:32:06,159 --> 00:32:08,960 uh there were many long days spent 943 00:32:07,519 --> 00:32:10,720 running after the kids followed by long 944 00:32:08,960 --> 00:32:12,320 night soldering um 945 00:32:10,720 --> 00:32:15,200 it wasn't easy and i definitely wouldn't 946 00:32:12,320 --> 00:32:16,399 recommend it 947 00:32:15,200 --> 00:32:18,320 uh so this is the point where it's 948 00:32:16,399 --> 00:32:21,120 nearly done no close-up photos of venue 949 00:32:18,320 --> 00:32:25,039 at this point i was definitely exhausted 950 00:32:21,120 --> 00:32:27,919 uh and uh yeah fairly stressed but um 951 00:32:25,039 --> 00:32:29,600 it it was very cool to look at it 952 00:32:27,919 --> 00:32:31,840 the nice side of it was that yeah the 953 00:32:29,600 --> 00:32:33,679 more leds that we put in and soldered 954 00:32:31,840 --> 00:32:36,320 the bigger and more beautiful the piece 955 00:32:33,679 --> 00:32:38,559 became which is really very cool 956 00:32:36,320 --> 00:32:38,559 um 957 00:32:39,760 --> 00:32:44,720 and although i didn't let my kids in 958 00:32:42,000 --> 00:32:46,399 very often um to see the piece the few 959 00:32:44,720 --> 00:32:48,960 occasions i did i'm actually really glad 960 00:32:46,399 --> 00:32:51,200 i did because to them it is 961 00:32:48,960 --> 00:32:53,120 significantly bigger or looks so much 962 00:32:51,200 --> 00:32:55,600 bigger than it does to me and seeing 963 00:32:53,120 --> 00:32:57,600 their faces react to 964 00:32:55,600 --> 00:32:59,840 the lighting effect was was very very 965 00:32:57,600 --> 00:33:01,840 cool so in some ways although it was 966 00:32:59,840 --> 00:33:05,440 really hard in some small other ways is 967 00:33:01,840 --> 00:33:05,440 also a little bit magical 968 00:33:06,960 --> 00:33:11,679 so there it all is it was all done 969 00:33:09,279 --> 00:33:14,159 all those seven panels and seven strings 970 00:33:11,679 --> 00:33:15,600 of leds are all wired up and ready to go 971 00:33:14,159 --> 00:33:18,640 very exciting 972 00:33:15,600 --> 00:33:21,919 so believe that was done 973 00:33:18,640 --> 00:33:25,200 and um oh there's a is my husband john a 974 00:33:21,919 --> 00:33:27,120 rare sighting of him i helped me uh flip 975 00:33:25,200 --> 00:33:28,480 the whole thing over so very carefully 976 00:33:27,120 --> 00:33:30,399 kind of rolled it up onto a tube and 977 00:33:28,480 --> 00:33:32,480 unraveled it again so that uh it would 978 00:33:30,399 --> 00:33:33,760 be lowest impact on me on the lights and 979 00:33:32,480 --> 00:33:35,519 the wiring 980 00:33:33,760 --> 00:33:38,399 and then we laid the tapestry back over 981 00:33:35,519 --> 00:33:40,880 the top to see uh how accurately 982 00:33:38,399 --> 00:33:43,760 everything ended up uh if anything was 983 00:33:40,880 --> 00:33:46,000 suddenly surprisingly wonky or or if any 984 00:33:43,760 --> 00:33:48,279 of the any of the leds were off their 985 00:33:46,000 --> 00:33:51,440 stars but it turned out to be 986 00:33:48,279 --> 00:33:53,120 remarkably accurate which is so cool 987 00:33:51,440 --> 00:33:55,679 right it's so amazing that you know 988 00:33:53,120 --> 00:33:57,440 after so much work and so you know under 989 00:33:55,679 --> 00:33:59,679 quite stressful situations that it all 990 00:33:57,440 --> 00:34:01,279 just kind of worked out in the end um 991 00:33:59,679 --> 00:34:03,039 and also knitting happens to be quite 992 00:34:01,279 --> 00:34:04,320 forgiving as well it's it's stretchy and 993 00:34:03,039 --> 00:34:06,080 it's malleable and if something's 994 00:34:04,320 --> 00:34:09,440 slightly off you can just you know nudge 995 00:34:06,080 --> 00:34:09,440 the knitting and everything's fine 996 00:34:10,720 --> 00:34:13,919 right so we've got 10 minutes to go and 997 00:34:12,879 --> 00:34:15,440 i still haven't talked to you about the 998 00:34:13,919 --> 00:34:16,560 interactive side of things so there's 999 00:34:15,440 --> 00:34:17,839 not much i can actually show you at this 1000 00:34:16,560 --> 00:34:20,560 point because it's still going through 1001 00:34:17,839 --> 00:34:22,560 the final phase and design a visual 1002 00:34:20,560 --> 00:34:24,639 graphic design but the intention for the 1003 00:34:22,560 --> 00:34:26,240 interactive component is basically to 1004 00:34:24,639 --> 00:34:28,320 coming back to that science versus art 1005 00:34:26,240 --> 00:34:30,240 idea um there's one piece of the 1006 00:34:28,320 --> 00:34:32,159 interactive which lets you learn about 1007 00:34:30,240 --> 00:34:34,000 the stars and learn a little bit of 1008 00:34:32,159 --> 00:34:36,720 astronomy and and look up the planets 1009 00:34:34,000 --> 00:34:38,159 and and uh and you know 1010 00:34:36,720 --> 00:34:40,000 get to appreciate the map from a 1011 00:34:38,159 --> 00:34:41,440 scientific space but also there's 1012 00:34:40,000 --> 00:34:42,240 another half of the interactive piece 1013 00:34:41,440 --> 00:34:45,760 which 1014 00:34:42,240 --> 00:34:47,280 you know the tapestry itself is a giant 1015 00:34:45,760 --> 00:34:48,879 uh light show 1016 00:34:47,280 --> 00:34:50,560 so the other half of the interactive 1017 00:34:48,879 --> 00:34:54,240 actually lets people jump in and create 1018 00:34:50,560 --> 00:34:55,440 their own light show using the uh the um 1019 00:34:54,240 --> 00:34:57,520 the interactive interface which is 1020 00:34:55,440 --> 00:35:00,240 really really cool and with these two 1021 00:34:57,520 --> 00:35:02,000 different pieces combined the there's a 1022 00:35:00,240 --> 00:35:04,160 third state for the tapestry which is 1023 00:35:02,000 --> 00:35:05,599 where it comes alive so the id being if 1024 00:35:04,160 --> 00:35:08,400 no one's actually interacting with it 1025 00:35:05,599 --> 00:35:10,480 then it takes the logs from the previous 1026 00:35:08,400 --> 00:35:13,200 uh art and science interactions and 1027 00:35:10,480 --> 00:35:16,400 actually combines them and in it in its 1028 00:35:13,200 --> 00:35:19,280 own way into a really beautiful light 1029 00:35:16,400 --> 00:35:20,079 show combining both art and science 1030 00:35:19,280 --> 00:35:21,599 um 1031 00:35:20,079 --> 00:35:23,839 so don't ask me about that algorithm i'm 1032 00:35:21,599 --> 00:35:25,440 still working on it i'm incorporating a 1033 00:35:23,839 --> 00:35:28,400 decay feature so that it will change 1034 00:35:25,440 --> 00:35:30,480 over time so uh it's a lonelier to show 1035 00:35:28,400 --> 00:35:32,160 um you know what people have been doing 1036 00:35:30,480 --> 00:35:34,079 uh or interacting with it recently 1037 00:35:32,160 --> 00:35:35,680 rather than the entire duration of the 1038 00:35:34,079 --> 00:35:38,000 of the exhibition so if you come and 1039 00:35:35,680 --> 00:35:41,040 visit it again it should actually be it 1040 00:35:38,000 --> 00:35:41,040 should actually look quite different 1041 00:35:42,320 --> 00:35:46,960 um also the technology side of things is 1042 00:35:45,200 --> 00:35:49,280 very different to how we had it set up 1043 00:35:46,960 --> 00:35:51,119 for emf cams so the 1044 00:35:49,280 --> 00:35:52,960 wi-fi at the state library victoria 1045 00:35:51,119 --> 00:35:55,040 isn't entirely reliable largely because 1046 00:35:52,960 --> 00:35:56,640 it's a it's an 1800s building it was 1047 00:35:55,040 --> 00:35:58,400 never really designed for modern 1048 00:35:56,640 --> 00:36:00,480 technology so 1049 00:35:58,400 --> 00:36:03,280 i've redesigned this to be completely 1050 00:36:00,480 --> 00:36:05,119 standalone uh this uh with the two 1051 00:36:03,280 --> 00:36:06,240 tablets connecting to the tapestry via 1052 00:36:05,119 --> 00:36:08,240 bluetooth 1053 00:36:06,240 --> 00:36:09,680 and the in order to do that there had to 1054 00:36:08,240 --> 00:36:11,280 be native 1055 00:36:09,680 --> 00:36:13,920 native apps so 1056 00:36:11,280 --> 00:36:16,560 i used react native to build that to an 1057 00:36:13,920 --> 00:36:18,480 android app uh which enables tablets to 1058 00:36:16,560 --> 00:36:20,240 talk to the tabs by bluetooth that's 1059 00:36:18,480 --> 00:36:22,560 really cool right because i don't think 1060 00:36:20,240 --> 00:36:23,760 this was even possible two years ago i 1061 00:36:22,560 --> 00:36:25,280 think this is still 1062 00:36:23,760 --> 00:36:28,000 kind of a new thing 1063 00:36:25,280 --> 00:36:29,359 um relatively new capability that i've 1064 00:36:28,000 --> 00:36:30,720 never played with before and i was 1065 00:36:29,359 --> 00:36:31,839 really thoroughly enjoying you could 1066 00:36:30,720 --> 00:36:33,440 even have a brick wall between the 1067 00:36:31,839 --> 00:36:36,400 tablets and tapestry and it would still 1068 00:36:33,440 --> 00:36:36,400 work which is really awesome 1069 00:36:38,640 --> 00:36:43,520 uh and there it is again we've got the 1070 00:36:40,880 --> 00:36:46,160 uh the prototype uh coming back into 1071 00:36:43,520 --> 00:36:48,000 into uh uh regular use so this is 1072 00:36:46,160 --> 00:36:49,440 actually uh we did some user testing 1073 00:36:48,000 --> 00:36:52,800 back in december which was a lot of fun 1074 00:36:49,440 --> 00:36:55,680 to see how people use this app uh and 1075 00:36:52,800 --> 00:36:57,119 and and the delight on their faces to 1076 00:36:55,680 --> 00:36:59,680 see what they do in the app actually 1077 00:36:57,119 --> 00:37:00,960 changes a real live physical device 1078 00:36:59,680 --> 00:37:03,200 which is really awesome when the two 1079 00:37:00,960 --> 00:37:04,320 aren't even physically connected so um 1080 00:37:03,200 --> 00:37:06,400 it did 1081 00:37:04,320 --> 00:37:07,680 cause quite uh quite a lot of excitement 1082 00:37:06,400 --> 00:37:09,920 uh when we were doing some music testing 1083 00:37:07,680 --> 00:37:09,920 on that 1084 00:37:10,400 --> 00:37:14,000 i have i don't think anyone's ever seen 1085 00:37:12,640 --> 00:37:15,119 the whole thing put together yet and i 1086 00:37:14,000 --> 00:37:17,440 don't think that's gonna be something 1087 00:37:15,119 --> 00:37:20,079 anyone will see until maybe a month at 1088 00:37:17,440 --> 00:37:22,000 most before the exhibition so this is 1089 00:37:20,079 --> 00:37:24,960 really kind of the best the best photos 1090 00:37:22,000 --> 00:37:24,960 i can give you at this point 1091 00:37:25,839 --> 00:37:29,839 so 1092 00:37:27,200 --> 00:37:29,839 in closing 1093 00:37:30,079 --> 00:37:33,920 the star map has been referred to by 1094 00:37:31,599 --> 00:37:35,520 many as a work of innovation 1095 00:37:33,920 --> 00:37:36,400 but in the western culture there still 1096 00:37:35,520 --> 00:37:37,920 exists 1097 00:37:36,400 --> 00:37:40,079 even today 1098 00:37:37,920 --> 00:37:41,760 strong social conventions that tell us 1099 00:37:40,079 --> 00:37:44,400 what we can and can't do 1100 00:37:41,760 --> 00:37:45,920 boys can't knit and girls can't code 1101 00:37:44,400 --> 00:37:48,720 so i realize this might sound a little 1102 00:37:45,920 --> 00:37:50,160 bit contrived but i genuinely believe 1103 00:37:48,720 --> 00:37:51,760 there are thousands of amazing 1104 00:37:50,160 --> 00:37:54,160 innovations still to be discovered out 1105 00:37:51,760 --> 00:37:57,520 there that sit at the union between one 1106 00:37:54,160 --> 00:37:58,240 social convention and another 1107 00:37:57,520 --> 00:38:00,320 so 1108 00:37:58,240 --> 00:38:02,000 instead of telling yourself 1109 00:38:00,320 --> 00:38:04,720 knitting isn't for me 1110 00:38:02,000 --> 00:38:05,680 i can't hack a mechanical device 1111 00:38:04,720 --> 00:38:08,400 well 1112 00:38:05,680 --> 00:38:08,400 what if you did 1113 00:38:12,640 --> 00:38:17,599 and that's everything 1114 00:38:14,560 --> 00:38:20,800 thank you everyone it's quite a yarn 1115 00:38:17,599 --> 00:38:20,800 do you have any questions at this point 1116 00:38:22,240 --> 00:38:26,160 that was amazing and there's so much 1117 00:38:23,920 --> 00:38:27,920 love coming through in the uh the chat 1118 00:38:26,160 --> 00:38:30,240 during your talk it's it's quite 1119 00:38:27,920 --> 00:38:32,800 inspiring i think the night sky has 1120 00:38:30,240 --> 00:38:35,040 something powerful to inspire people and 1121 00:38:32,800 --> 00:38:37,440 i think you've captured that really well 1122 00:38:35,040 --> 00:38:39,200 um and that's yeah i think people are 1123 00:38:37,440 --> 00:38:42,079 certainly appreciating that as you well 1124 00:38:39,200 --> 00:38:44,000 know from your twitter store wow 1125 00:38:42,079 --> 00:38:45,599 um we do have some questions and we do 1126 00:38:44,000 --> 00:38:47,520 have a bit of time for them if you're if 1127 00:38:45,599 --> 00:38:50,160 you're willing to take some 1128 00:38:47,520 --> 00:38:51,839 absolutely so 1129 00:38:50,160 --> 00:38:54,079 i'll just go through these as they've 1130 00:38:51,839 --> 00:38:57,760 come in um 1131 00:38:54,079 --> 00:38:57,760 have you hacked the overlocker yet 1132 00:38:58,480 --> 00:39:02,240 that sounds awesome um if i could hack 1133 00:39:00,320 --> 00:39:04,000 the overlocker so that it 1134 00:39:02,240 --> 00:39:04,880 um automatically threads for me so i 1135 00:39:04,000 --> 00:39:07,280 don't have to thread it that'd be 1136 00:39:04,880 --> 00:39:08,880 fantastic so uh not yet 1137 00:39:07,280 --> 00:39:13,359 stay tuned 1138 00:39:08,880 --> 00:39:15,760 not not yet then on the roadmap perhaps 1139 00:39:13,359 --> 00:39:17,280 around um orientation of the printed 1140 00:39:15,760 --> 00:39:18,320 panels and so 1141 00:39:17,280 --> 00:39:20,720 it was 1142 00:39:18,320 --> 00:39:22,400 why was the decision made to hang them 1143 00:39:20,720 --> 00:39:25,520 vertically as opposed to horizontally 1144 00:39:22,400 --> 00:39:25,520 was a structural thing 1145 00:39:25,680 --> 00:39:30,560 yep so 1146 00:39:26,839 --> 00:39:32,000 um it's because in hanging 1147 00:39:30,560 --> 00:39:34,480 the uh 1148 00:39:32,000 --> 00:39:36,240 all of the the gravitational weight is 1149 00:39:34,480 --> 00:39:38,079 on those stitches and the stitches are 1150 00:39:36,240 --> 00:39:39,440 the weak point in the piece so 1151 00:39:38,079 --> 00:39:41,440 particularly if something is going to be 1152 00:39:39,440 --> 00:39:43,280 preserved for a really long time you 1153 00:39:41,440 --> 00:39:44,960 don't and and you know the intent for it 1154 00:39:43,280 --> 00:39:46,480 is to engage young minds in science you 1155 00:39:44,960 --> 00:39:49,040 want it to be on display as much as 1156 00:39:46,480 --> 00:39:50,800 possible so you don't you know you don't 1157 00:39:49,040 --> 00:39:52,160 want actually the process of hanging it 1158 00:39:50,800 --> 00:39:53,680 to cause it to 1159 00:39:52,160 --> 00:39:56,680 become more and more 1160 00:39:53,680 --> 00:39:56,680 um 1161 00:39:57,040 --> 00:40:02,079 fragile so a vertical seam doesn't have 1162 00:40:00,000 --> 00:40:05,200 the gravitational uh effects on it the 1163 00:40:02,079 --> 00:40:05,200 way a horizontal scene does 1164 00:40:06,000 --> 00:40:11,119 next question so this is a clearly a 1165 00:40:08,800 --> 00:40:13,440 long process how did you manage to 1166 00:40:11,119 --> 00:40:15,440 maintain focus and momentum um 1167 00:40:13,440 --> 00:40:17,599 particularly in the face of a global 1168 00:40:15,440 --> 00:40:19,520 pandemic and having kids and everything 1169 00:40:17,599 --> 00:40:21,040 else so 1170 00:40:19,520 --> 00:40:22,400 what's your secret i think is kind of 1171 00:40:21,040 --> 00:40:23,520 the question 1172 00:40:22,400 --> 00:40:25,599 of course 1173 00:40:23,520 --> 00:40:27,280 um there's a great quote that i have on 1174 00:40:25,599 --> 00:40:29,920 a um and i posted here actually right on 1175 00:40:27,280 --> 00:40:32,720 my on my screen here it is 1176 00:40:29,920 --> 00:40:35,359 uh it says i didn't come this far 1177 00:40:32,720 --> 00:40:36,960 just to come this far 1178 00:40:35,359 --> 00:40:38,960 and i find that really helps me rephrase 1179 00:40:36,960 --> 00:40:40,240 things because it it can feel exhausting 1180 00:40:38,960 --> 00:40:42,240 and you can get to the point where where 1181 00:40:40,240 --> 00:40:43,440 you're like enough is enough i'm over it 1182 00:40:42,240 --> 00:40:45,040 it's done 1183 00:40:43,440 --> 00:40:47,280 to sell the thing 1184 00:40:45,040 --> 00:40:49,520 but you know when when you've made such 1185 00:40:47,280 --> 00:40:50,720 an impact and you've you've achieved so 1186 00:40:49,520 --> 00:40:53,119 much 1187 00:40:50,720 --> 00:40:56,000 it is such a shame to just let it all 1188 00:40:53,119 --> 00:40:56,960 drop and and let it all go um i feel 1189 00:40:56,000 --> 00:40:58,400 like this thing really needs to be 1190 00:40:56,960 --> 00:41:00,400 finished and i feel like the star map 1191 00:40:58,400 --> 00:41:04,160 deserves a final home so 1192 00:41:00,400 --> 00:41:04,160 um that's what i've been focusing on 1193 00:41:04,240 --> 00:41:06,800 okay 1194 00:41:05,280 --> 00:41:08,079 the questions are coming in thick and 1195 00:41:06,800 --> 00:41:09,760 fast now and we're lucky because we 1196 00:41:08,079 --> 00:41:11,040 actually have some time to answer them 1197 00:41:09,760 --> 00:41:13,200 um 1198 00:41:11,040 --> 00:41:15,280 is the library or the museum going to be 1199 00:41:13,200 --> 00:41:17,040 storing a digital archive of the design 1200 00:41:15,280 --> 00:41:18,880 do you know 1201 00:41:17,040 --> 00:41:20,400 yes i believe um 1202 00:41:18,880 --> 00:41:22,000 when i made the donation a big part of 1203 00:41:20,400 --> 00:41:23,920 the donation was the digital artifacts 1204 00:41:22,000 --> 00:41:24,880 that golden with it so the knitting 1205 00:41:23,920 --> 00:41:27,200 machine 1206 00:41:24,880 --> 00:41:28,480 files that i used that i generated and 1207 00:41:27,200 --> 00:41:31,359 used to create the startup are being 1208 00:41:28,480 --> 00:41:34,319 stored as well as the original 1209 00:41:31,359 --> 00:41:36,079 graphic image 1210 00:41:34,319 --> 00:41:37,760 cool another one that's kind of i guess 1211 00:41:36,079 --> 00:41:39,680 there's a couple of questions that are 1212 00:41:37,760 --> 00:41:41,839 more around like questions of have you 1213 00:41:39,680 --> 00:41:44,000 tried this in the design and did you do 1214 00:41:41,839 --> 00:41:45,920 that so one of them was have you thought 1215 00:41:44,000 --> 00:41:48,160 about doing a continuous strip of pixels 1216 00:41:45,920 --> 00:41:51,119 along the elliptic so it could show the 1217 00:41:48,160 --> 00:41:53,760 current position of sun and planets 1218 00:41:51,119 --> 00:41:55,920 i i love that that's what sewing 1219 00:41:53,760 --> 00:41:58,319 suggested because that was actually part 1220 00:41:55,920 --> 00:42:00,319 of the original spec so before the long 1221 00:41:58,319 -->
