[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

207
00:07:23,039 --> 00:07:26,720
fly to the uk now i just need to pack

208
00:07:25,120 --> 00:07:28,960
the entire universe in my suitcase i'll

209
00:07:26,720 --> 00:07:30,560
see you all soon

210
00:07:28,960 --> 00:07:32,880
and before i went to bed that night

211
00:07:30,560 --> 00:07:34,720
there was about 50 likes i think and i

212
00:07:32,880 --> 00:07:35,759
thought oh that's fantastic 50 likes wow

213
00:07:34,720 --> 00:07:38,479
nothing i've ever done has been that

214
00:07:35,759 --> 00:07:39,520
like that much that's that's really cool

215
00:07:38,479 --> 00:07:41,599
and

216
00:07:39,520 --> 00:07:43,840
in the ensuring days

217
00:07:41,599 --> 00:07:45,840
things went nuts i was on the plane to

218
00:07:43,840 --> 00:07:48,319
the uk and i was in the middle of a

219
00:07:45,840 --> 00:07:50,560
field in the in in uh

220
00:07:48,319 --> 00:07:52,160
at emf camp and yeah i was busy doing a

221
00:07:50,560 --> 00:07:54,639
lot of things but the internet had a

222
00:07:52,160 --> 00:07:55,919
whole different idea about uh you know

223
00:07:54,639 --> 00:07:58,639
where this where this piece should go

224
00:07:55,919 --> 00:08:00,720
which is astonishing fourteen thousand

225
00:07:58,639 --> 00:08:02,960
weighed seven two thousand likes and

226
00:08:00,720 --> 00:08:05,120
including the long tails seven million

227
00:08:02,960 --> 00:08:08,879
impressions uh i've never gone viral

228
00:08:05,120 --> 00:08:11,120
before and that was quite an experience

229
00:08:08,879 --> 00:08:13,039
um so i did because i wasn't actually

230
00:08:11,120 --> 00:08:14,720
keeping track of all of this i was you

231
00:08:13,039 --> 00:08:16,560
know in the air for 24 hours of it i

232
00:08:14,720 --> 00:08:18,479
really wanted to go back and see what

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 the

242
00:08:33,599 --> 00:08:38,159
viral retweets and quotes uh and

243
00:08:36,240 --> 00:08:39,200
cumulative tweets showing the total

244
00:08:38,159 --> 00:08:41,680
number of

245
00:08:39,200 --> 00:08:43,200
retweets and quotes uh over over the

246
00:08:41,680 --> 00:08:44,720
time period all of the bubbles

247
00:08:43,200 --> 00:08:46,480
representing the followers for 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
00:09:00,399 --> 00:09:06,080
um i do wanna say that the the first

258
00:09:02,160 --> 00:09:08,800
three retweeters were uh john spencer um

259
00:09:06,080 --> 00:09:11,040
david bell and andy gilmay are all from

260
00:09:08,800 --> 00:09:12,880
linux conf so uh it really does show

261
00:09:11,040 --> 00:09:13,760
that when linux people are retweeting

262
00:09:12,880 --> 00:09:15,200
something you should really pay

263
00:09:13,760 --> 00:09:16,959
attention because uh it's definitely

264
00:09:15,200 --> 00:09:18,080
worth checking out

265
00:09:16,959 --> 00:09:19,920
um

266
00:09:18,080 --> 00:09:23,360
but yeah at the very peak of the curve

267
00:09:19,920 --> 00:09:25,360
here um bad astronomer uh this this

268
00:09:23,360 --> 00:09:27,519
quote tweet here really did kick off an

269
00:09:25,360 --> 00:09:29,760
awful lot of activity so bad astronomer

270
00:09:27,519 --> 00:09:32,480
phil plate in the usa thank you so much

271
00:09:29,760 --> 00:09:34,240
that was uh that was incredible uh a few

272
00:09:32,480 --> 00:09:37,519
other interesting characters here rufus

273
00:09:34,240 --> 00:09:39,360
hound who's a uk actor um i think uh

274
00:09:37,519 --> 00:09:41,040
in the first two and a half hours in

275
00:09:39,360 --> 00:09:43,040
this block here we've also got

276
00:09:41,040 --> 00:09:45,279
star talk radio

277
00:09:43,040 --> 00:09:48,080
which for those uh who might not be

278
00:09:45,279 --> 00:09:50,560
familiar is a show hosted by

279
00:09:48,080 --> 00:09:52,640
neil degrasse tyson and to think they

280
00:09:50,560 --> 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

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

um so more about the exhibition there

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 --> 00:42:02,960
lock down i did want to put in a whole

1222
00:42:00,319 --> 00:42:05,440
separate string of leds through

1223
00:42:02,960 --> 00:42:08,400
the the um

1224
00:42:05,440 --> 00:42:12,560
eclipse the equatorial line

1225
00:42:08,400 --> 00:42:12,560
uh ran out of time on that one sorry

1226
00:42:13,119 --> 00:42:16,400
um i have a question that i thought of

1227
00:42:15,119 --> 00:42:18,960
because i've done

1228
00:42:16,400 --> 00:42:20,560
bad things with leds in the past

1229
00:42:18,960 --> 00:42:22,240
what were you doing for the fire

1230
00:42:20,560 --> 00:42:24,240
retardant like how many fuses were

1231
00:42:22,240 --> 00:42:26,720
involved did you have one on each panel

1232
00:42:24,240 --> 00:42:26,720
or like

1233
00:42:28,079 --> 00:42:31,079
um

1234
00:42:31,520 --> 00:42:34,800
no i don't i don't think so

1235
00:42:35,359 --> 00:42:40,079
okay i'm gonna we're gonna put that into

1236
00:42:37,839 --> 00:42:42,720
the link no don't ask don't tell because

1237
00:42:40,079 --> 00:42:45,680
yeah confuses are important in projects

1238
00:42:42,720 --> 00:42:46,800
it turns out with neopixels

1239
00:42:45,680 --> 00:42:49,359
um

1240
00:42:46,800 --> 00:42:50,880
cool i i think that's pretty much what

1241
00:42:49,359 --> 00:42:52,560
we had up there's a couple no there's

1242
00:42:50,880 --> 00:42:54,960
some more have come in as i said people

1243
00:42:52,560 --> 00:42:57,119
are just hammering this at the end

1244
00:42:54,960 --> 00:42:59,599
uh you've conquered the observable

1245
00:42:57,119 --> 00:43:01,040
universe what next i think the question

1246
00:42:59,599 --> 00:43:02,800
is related there's another one that's

1247
00:43:01,040 --> 00:43:04,400
what is your next project i think is

1248
00:43:02,800 --> 00:43:05,280
basically what what we're getting at

1249
00:43:04,400 --> 00:43:07,920
there

1250
00:43:05,280 --> 00:43:09,760
yeah um fair question

1251
00:43:07,920 --> 00:43:11,760
i have been asked this a lot and i still

1252
00:43:09,760 --> 00:43:15,200
don't have a good answer i think right

1253
00:43:11,760 --> 00:43:15,200
now i'd really like to go on holiday

1254
00:43:16,480 --> 00:43:19,280
i i hear that

1255
00:43:19,599 --> 00:43:23,040
cool all right well i think we're gonna

1256
00:43:21,200 --> 00:43:24,880
wrap up that was a really good talk

1257
00:43:23,040 --> 00:43:28,319
thank you so much for your time sarah um

1258
00:43:24,880 --> 00:43:30,000
we're going into afternoon tea or

1259
00:43:28,319 --> 00:43:31,760
for us of us in new zealand or dinner

1260
00:43:30,000 --> 00:43:34,800
break

1261
00:43:31,760 --> 00:43:37,359
and we'll be back in

1262
00:43:34,800 --> 00:43:38,240
what is that it will be

1263
00:43:37,359 --> 00:43:40,480
about

1264
00:43:38,240 --> 00:43:42,720
30 minutes so we'll see you all back

1265
00:43:40,480 --> 00:43:47,880
here at 3

1266
00:43:42,720 --> 00:43:47,880
45 australian eastern standard time
