00:00:00,000 --> 00:00:03,000
foreign

00:00:04,960 --> 00:00:08,490
[Music]

3
00:00:11,460 --> 00:00:15,860
thank you everyone thanks for coming

4
00:00:13,620 --> 00:00:15,860
along

5
00:00:17,160 --> 00:00:22,320
I just first like to say welcome to

6
00:00:20,340 --> 00:00:24,060
Country I would like to begin by

7
00:00:22,320 --> 00:00:27,240
acknowledging the people of the Kula

8
00:00:24,060 --> 00:00:29,220
Nations the traditional custodians of

9
00:00:27,240 --> 00:00:32,579
the lands of Nam and the surrounding

10
00:00:29,220 --> 00:00:35,780
areas I pay my respects to their Elders

11
00:00:32,579 --> 00:00:35,780
past and present

12
00:00:36,000 --> 00:00:38,300
we're here to talk about some lovely

13
00:00:37,559 --> 00:00:41,520
flowers

14
00:00:38,300 --> 00:00:45,899
and when you have a flower you've got

15
00:00:41,520 --> 00:00:52,320
pollinators so we're going to try and

16
00:00:45,899 --> 00:00:55,199
set out to discover a pollinator for a

17
00:00:52,320 --> 00:00:56,340
little flat an orchid that lives in my

18
00:00:55,199 --> 00:00:59,399
area

19
00:00:56,340 --> 00:01:02,280
so I live in at Bustleton Western

20
00:00:59,399 --> 00:01:03,840
Australia right down the bottom South

21
00:01:02,280 --> 00:01:05,820
West corner

22
00:01:03,840 --> 00:01:09,479
of wa

23
00:01:05,820 --> 00:01:13,020
and there are 117 native terrestrial

24
00:01:09,479 --> 00:01:15,720
orchids in my local so you could say 50

25
00:01:13,020 --> 00:01:18,420
kilometer area

26
00:01:15,720 --> 00:01:20,159
um and these are some of them uh that

27
00:01:18,420 --> 00:01:22,140
I've photographed and around in around

28
00:01:20,159 --> 00:01:23,220
my area

29
00:01:22,140 --> 00:01:25,320
um

30
00:01:23,220 --> 00:01:29,600
and

31
00:01:25,320 --> 00:01:33,259
yeah and so then you have uh pollinators

32
00:01:29,600 --> 00:01:36,840
uh wasps uh bull ants

33
00:01:33,259 --> 00:01:38,820
and you can see a thinner wasp there and

34
00:01:36,840 --> 00:01:40,439
you'll see on its back

35
00:01:38,820 --> 00:01:44,400
um the yellow

36
00:01:40,439 --> 00:01:46,880
packets on the back polymer sex so

37
00:01:44,400 --> 00:01:50,540
orchids well at least in my area

38
00:01:46,880 --> 00:01:54,240
generally don't have fluffy powdery

39
00:01:50,540 --> 00:01:56,640
pollen they've got pollener sacs and

40
00:01:54,240 --> 00:01:58,680
they're sticky sacks that the insect

41
00:01:56,640 --> 00:02:01,200
goes in and they just stick on the back

42
00:01:58,680 --> 00:02:03,799
and it flows off to the next one and

43
00:02:01,200 --> 00:02:03,799
propagates

44
00:02:04,020 --> 00:02:06,619
so

45
00:02:07,020 --> 00:02:13,260
and here's a thinner boss just to show

46
00:02:09,899 --> 00:02:15,720
you the size of it so it's about 20

47
00:02:13,260 --> 00:02:18,360
millimeters long and that was on my

48
00:02:15,720 --> 00:02:20,160
finger just I'm doing something and all

49
00:02:18,360 --> 00:02:25,200
of a sudden this thinner wasp lands yeah

50
00:02:20,160 --> 00:02:26,940
whoa okay they don't sting native Wasp

51
00:02:25,200 --> 00:02:31,200
from Australia

52
00:02:26,940 --> 00:02:32,660
but uh so quite a few years ago now I

53
00:02:31,200 --> 00:02:36,720
was

54
00:02:32,660 --> 00:02:39,800
going on a walk and with a professor a

55
00:02:36,720 --> 00:02:44,400
professor Mark Brandon brunderett

56
00:02:39,800 --> 00:02:46,620
from one of the Unis in wa there and we

57
00:02:44,400 --> 00:02:49,920
were chatting about pollinators and why

58
00:02:46,620 --> 00:02:52,739
they were important Etc and he said well

59
00:02:49,920 --> 00:02:55,379
coincidentally no one knows for he said

60
00:02:52,739 --> 00:02:59,819
for example no one knows what pollinates

61
00:02:55,379 --> 00:03:03,739
the uh helmet Orchid I thought okay the

62
00:02:59,819 --> 00:03:07,260
helmet orchid's not rare it's

63
00:03:03,739 --> 00:03:10,019
in the west also up the East Coast

64
00:03:07,260 --> 00:03:12,180
so you know how hard can it be to try

65
00:03:10,019 --> 00:03:13,739
and find the pollinator of the helmet

66
00:03:12,180 --> 00:03:16,800
orchid

67
00:03:13,739 --> 00:03:19,459
so coincidentally

68
00:03:16,800 --> 00:03:23,720
um 10 years earlier than that

69
00:03:19,459 --> 00:03:28,200
a lady Jenny was showing me around

70
00:03:23,720 --> 00:03:31,319
and this is a typical example of the

71
00:03:28,200 --> 00:03:34,440
habitat and so this log here

72
00:03:31,319 --> 00:03:36,300
has about three species of orchids on

73
00:03:34,440 --> 00:03:41,700
there and

74
00:03:36,300 --> 00:03:44,220
um so you can see the the green leaf and

75
00:03:41,700 --> 00:03:45,959
it's a beautiful log and it's it's quite

76
00:03:44,220 --> 00:03:49,200
stunning when you see it all the the

77
00:03:45,959 --> 00:03:51,840
flowers on it and what have you and uh

78
00:03:49,200 --> 00:03:55,019
so I thought okay I'm she's showing me

79
00:03:51,840 --> 00:03:57,180
this uh so let's go and try and find

80
00:03:55,019 --> 00:03:58,620
this log and I can just base everything

81
00:03:57,180 --> 00:04:00,959
from that

82
00:03:58,620 --> 00:04:04,319
so

83
00:04:00,959 --> 00:04:06,840
I set out this is remember 10 years had

84
00:04:04,319 --> 00:04:10,140
gone past and she'd just taken me on

85
00:04:06,840 --> 00:04:13,140
this and so I spent a couple of years

86
00:04:10,140 --> 00:04:15,599
actually just every now and then feeling

87
00:04:13,140 --> 00:04:18,720
the mood go for a walk and this is just

88
00:04:15,599 --> 00:04:22,079
two of my walks tracking uh where I was

89
00:04:18,720 --> 00:04:24,780
going so I could see uh it's in a

90
00:04:22,079 --> 00:04:26,820
specific habitat so there's some areas

91
00:04:24,780 --> 00:04:31,080
that I'd missed but I'd covered in other

92
00:04:26,820 --> 00:04:33,960
years so uh yes but I did not find that

93
00:04:31,080 --> 00:04:36,900
log because

94
00:04:33,960 --> 00:04:39,060
it was a long way away from where I was

95
00:04:36,900 --> 00:04:41,699
looking so this is one block there's a

96
00:04:39,060 --> 00:04:45,419
track coming down through the middle

97
00:04:41,699 --> 00:04:49,320
um but yeah so vagaries of memory

98
00:04:45,419 --> 00:04:52,380
but while I was looking for that log

99
00:04:49,320 --> 00:04:55,820
uh I found another one and this is even

100
00:04:52,380 --> 00:04:59,940
more spectacular so this is a tree bow

101
00:04:55,820 --> 00:05:02,520
and it is about yay far off the ground I

102
00:04:59,940 --> 00:05:06,419
mean how nice is that photography level

103
00:05:02,520 --> 00:05:08,880
it's just like a bench sitting there and

104
00:05:06,419 --> 00:05:11,460
you can see all the helmet orchids uh

105
00:05:08,880 --> 00:05:14,820
growing in there all those red the red

106
00:05:11,460 --> 00:05:17,220
dots there as he walks off the stage

107
00:05:14,820 --> 00:05:20,160
um about yay big or so

108
00:05:17,220 --> 00:05:24,000
and it's very spectacular and you can

109
00:05:20,160 --> 00:05:25,919
get up to 60 flowers all all on there

110
00:05:24,000 --> 00:05:26,880
and it's all one species just one

111
00:05:25,919 --> 00:05:28,680
species

112
00:05:26,880 --> 00:05:30,600
so very pretty

113
00:05:28,680 --> 00:05:34,259
and you can see all the Moss so the

114
00:05:30,600 --> 00:05:35,280
flower grows in mainly in the Moss layer

115
00:05:34,259 --> 00:05:36,539
um

116
00:05:35,280 --> 00:05:39,539
yep

117
00:05:36,539 --> 00:05:42,240
so this is the target species

118
00:05:39,539 --> 00:05:45,780
um chorus

119
00:05:42,240 --> 00:05:48,240
corbis recover the leaf is about 20

120
00:05:45,780 --> 00:05:50,280
millimeters across and the flower is

121
00:05:48,240 --> 00:05:53,520
about 10 millimeters wide

122
00:05:50,280 --> 00:05:55,979
the top of the flower is about 12

123
00:05:53,520 --> 00:05:58,380
millimeters or so off the ground so you

124
00:05:55,979 --> 00:06:02,520
can see a side profile there and one

125
00:05:58,380 --> 00:06:04,860
that's full on so on the if I can get my

126
00:06:02,520 --> 00:06:08,460
mouse

127
00:06:04,860 --> 00:06:10,740
yep so if you look inside here you can

128
00:06:08,460 --> 00:06:11,580
see the cavity going in through the

129
00:06:10,740 --> 00:06:13,919
throat

130
00:06:11,580 --> 00:06:16,860
whoop

131
00:06:13,919 --> 00:06:19,160
turn off and you can see so here we are

132
00:06:16,860 --> 00:06:24,960
looking outside on the profile

133
00:06:19,160 --> 00:06:27,240
so uh the pollen assaq sits in here and

134
00:06:24,960 --> 00:06:30,240
the anther I think I'll talk about that

135
00:06:27,240 --> 00:06:34,440
later is just a little bit further down

136
00:06:30,240 --> 00:06:37,080
so it's like this inside the flower so

137
00:06:34,440 --> 00:06:40,560
if that opening is 12 millimeters across

138
00:06:37,080 --> 00:06:44,039
if that opening is 10 or so millimeters

139
00:06:40,560 --> 00:06:46,919
across you can imagine that here is only

140
00:06:44,039 --> 00:06:50,520
a couple of millimeters across if that

141
00:06:46,919 --> 00:06:52,860
so whatever goes in is small so that

142
00:06:50,520 --> 00:06:54,300
gives us an idea of what we're aiming

143
00:06:52,860 --> 00:06:57,120
for

144
00:06:54,300 --> 00:07:00,180
and

145
00:06:57,120 --> 00:07:02,060
it grows in

146
00:07:00,180 --> 00:07:07,440
mid to

147
00:07:02,060 --> 00:07:10,319
July August in a dark wet Forest

148
00:07:07,440 --> 00:07:13,319
so you think yeah that's pretty easy

149
00:07:10,319 --> 00:07:16,319
until you go to that dark wet forest in

150
00:07:13,319 --> 00:07:19,080
the middle of winter and you are covered

151
00:07:16,319 --> 00:07:20,759
in maybe 200 mosquitoes

152
00:07:19,080 --> 00:07:23,360
Etc so

153
00:07:20,759 --> 00:07:23,360
yep

154
00:07:23,699 --> 00:07:29,880
so there's another species

155
00:07:26,000 --> 00:07:32,699
this one is coribus to spectons and it

156
00:07:29,880 --> 00:07:34,800
comes out maybe two weeks afterwards so

157
00:07:32,699 --> 00:07:36,599
there's a bit of an overlap you get

158
00:07:34,800 --> 00:07:38,759
maybe two or three weeks with the first

159
00:07:36,599 --> 00:07:43,860
one and then two weeks for this other

160
00:07:38,759 --> 00:07:46,919
one this one is smaller so this is a

161
00:07:43,860 --> 00:07:48,840
side profile but the opening is even

162
00:07:46,919 --> 00:07:51,419
smaller so we're you know we're talking

163
00:07:48,840 --> 00:07:53,039
about something this big the ground and

164
00:07:51,419 --> 00:07:54,620
then it's poking up through the ground

165
00:07:53,039 --> 00:07:59,060
there

166
00:07:54,620 --> 00:07:59,060
but this is a quite a beautiful flower

167
00:07:59,699 --> 00:08:08,639
so let's see what we can discover so

168
00:08:04,319 --> 00:08:11,580
Mark came down and we made up some traps

169
00:08:08,639 --> 00:08:13,860
and

170
00:08:11,580 --> 00:08:16,380
this was our first go we tried a couple

171
00:08:13,860 --> 00:08:18,780
of different traps that left hand one

172
00:08:16,380 --> 00:08:23,400
did not work at all so that was a

173
00:08:18,780 --> 00:08:26,099
failure but the right hand one kind of

174
00:08:23,400 --> 00:08:29,819
worked a little bit we'd placed it over

175
00:08:26,099 --> 00:08:33,659
the flower and it was raised up about

176
00:08:29,819 --> 00:08:35,580
four inches or so above the flower we

177
00:08:33,659 --> 00:08:38,459
caught some insects

178
00:08:35,580 --> 00:08:40,740
but uh nothing will with a pollen a sack

179
00:08:38,459 --> 00:08:42,120
on the back

180
00:08:40,740 --> 00:08:45,660
um

181
00:08:42,120 --> 00:08:47,700
um so we're thinking about that and then

182
00:08:45,660 --> 00:08:51,839
the next move I think he came down

183
00:08:47,700 --> 00:08:53,519
another time and uh in the meantime said

184
00:08:51,839 --> 00:08:56,940
yep I'd found this thing called

185
00:08:53,519 --> 00:09:00,839
tanglefoot from New Zealand and it's a

186
00:08:56,940 --> 00:09:02,100
paint on really really sticky glue shall

187
00:09:00,839 --> 00:09:02,820
we say

188
00:09:02,100 --> 00:09:05,720
um

189
00:09:02,820 --> 00:09:09,360
yeah it's transparent pretty neat stuff

190
00:09:05,720 --> 00:09:11,820
so we cut up some first off we cut up

191
00:09:09,360 --> 00:09:14,700
some just to what are they projection

192
00:09:11,820 --> 00:09:17,459
yeah the old projection plastic thing

193
00:09:14,700 --> 00:09:19,860
and we cut up some of those and we

194
00:09:17,459 --> 00:09:21,420
liberally painted it with a tangle foot

195
00:09:19,860 --> 00:09:24,060
on both sides

196
00:09:21,420 --> 00:09:25,800
stuck them all out and we're sort of

197
00:09:24,060 --> 00:09:26,880
finishing off the last couple of traps

198
00:09:25,800 --> 00:09:29,580
you know we'd put them in different

199
00:09:26,880 --> 00:09:33,180
areas log book noted where they all are

200
00:09:29,580 --> 00:09:35,459
date time Etc all very good and we're

201
00:09:33,180 --> 00:09:37,500
sort of walking back and I'm going how

202
00:09:35,459 --> 00:09:40,500
are we going to collect those that's

203
00:09:37,500 --> 00:09:44,220
going to be pretty sticky so we went off

204
00:09:40,500 --> 00:09:47,459
to lunch and uh you know this is

205
00:09:44,220 --> 00:09:49,980
very haphazard this project and so we

206
00:09:47,459 --> 00:09:52,500
ended up just getting a roll of um what

207
00:09:49,980 --> 00:09:54,120
do you call it Cloud wrap and just

208
00:09:52,500 --> 00:09:55,260
coating that but not very good for

209
00:09:54,120 --> 00:09:59,940
photography

210
00:09:55,260 --> 00:10:01,940
but anyway we refined it later on and

211
00:09:59,940 --> 00:10:01,940
um

212
00:10:03,300 --> 00:10:08,880
yep

213
00:10:04,800 --> 00:10:12,680
but uh here is some examples

214
00:10:08,880 --> 00:10:12,680
from that first batch of

215
00:10:12,920 --> 00:10:21,420
plastic sheets and so these are mainly

216
00:10:18,200 --> 00:10:23,220
insects on there are mainly fungus gnats

217
00:10:21,420 --> 00:10:24,720
the large ones there so they look like

218
00:10:23,220 --> 00:10:26,279
mosquitoes but they're a little bit

219
00:10:24,720 --> 00:10:29,220
smaller so just to give some size

220
00:10:26,279 --> 00:10:31,200
context on there

221
00:10:29,220 --> 00:10:36,720
yep

222
00:10:31,200 --> 00:10:38,940
but later on WE refined that and um

223
00:10:36,720 --> 00:10:41,060
I've got a fortune enough to have a

224
00:10:38,940 --> 00:10:44,220
laser cutter so

225
00:10:41,060 --> 00:10:46,500
standardized sized nice some grid

226
00:10:44,220 --> 00:10:50,399
references so you can count you know

227
00:10:46,500 --> 00:10:52,800
number of insects per per area Etc and

228
00:10:50,399 --> 00:10:55,920
date time on the or date at least on the

229
00:10:52,800 --> 00:10:58,680
site and the site name

230
00:10:55,920 --> 00:11:01,200
but then how do you store those so you

231
00:10:58,680 --> 00:11:04,800
got those out in the field so quick

232
00:11:01,200 --> 00:11:08,220
thinking and uh yep in with 3D printer

233
00:11:04,800 --> 00:11:10,980
and designing up a box 3D printing it

234
00:11:08,220 --> 00:11:13,140
and later that night had a nice little

235
00:11:10,980 --> 00:11:16,140
storage case for it and they all just

236
00:11:13,140 --> 00:11:18,360
slot in there it was beautiful

237
00:11:16,140 --> 00:11:21,959
so I now have many many many many many

238
00:11:18,360 --> 00:11:24,079
many boxes of these these uh over the

239
00:11:21,959 --> 00:11:24,079
years

240
00:11:25,200 --> 00:11:29,160
yep

241
00:11:27,300 --> 00:11:33,300
and we've had some results

242
00:11:29,160 --> 00:11:36,560
so you can see there's three fungus

243
00:11:33,300 --> 00:11:40,019
gnats there all with different shaped

244
00:11:36,560 --> 00:11:41,820
polymer sacks on their backs fantastic

245
00:11:40,019 --> 00:11:45,420
we're on a win

246
00:11:41,820 --> 00:11:47,279
but then you think hang on

247
00:11:45,420 --> 00:11:50,760
where did they come from

248
00:11:47,279 --> 00:11:52,519
and was it even a plant in my area you

249
00:11:50,760 --> 00:11:55,560
know I'm putting it over the plant

250
00:11:52,519 --> 00:11:57,120
roughly or patch of there but maybe they

251
00:11:55,560 --> 00:11:58,500
came from over there or maybe a

252
00:11:57,120 --> 00:12:03,000
kilometer away

253
00:11:58,500 --> 00:12:04,620
so uh at the time DNA was still quite

254
00:12:03,000 --> 00:12:06,180
expensive I think it was about two

255
00:12:04,620 --> 00:12:08,399
thousand dollars a pop we did talk about

256
00:12:06,180 --> 00:12:10,920
that but this is citizen science and

257
00:12:08,399 --> 00:12:12,600
this citizen doesn't have really or my

258
00:12:10,920 --> 00:12:14,640
wife wouldn't think two thousand dollars

259
00:12:12,600 --> 00:12:16,620
would be a pretty good investment but

260
00:12:14,640 --> 00:12:19,500
anyway we've still got all of this so

261
00:12:16,620 --> 00:12:23,399
over time think prices will come down

262
00:12:19,500 --> 00:12:25,680
so we might be able to do that so I then

263
00:12:23,399 --> 00:12:26,959
went around and tried collecting some

264
00:12:25,680 --> 00:12:30,180
samples

265
00:12:26,959 --> 00:12:34,440
so going around to each different flower

266
00:12:30,180 --> 00:12:36,600
and then trying to photograph them and

267
00:12:34,440 --> 00:12:38,519
I've got an array of

268
00:12:36,600 --> 00:12:41,760
toothpicks they're just all toothpicks

269
00:12:38,519 --> 00:12:44,100
to give us a size dimension it's pretty

270
00:12:41,760 --> 00:12:46,500
small not very big

271
00:12:44,100 --> 00:12:50,480
but better than pollen you know the

272
00:12:46,500 --> 00:12:50,480
pollen I suppose that just floats around

273
00:12:51,120 --> 00:12:56,579
right so time to go high tech

274
00:12:54,600 --> 00:12:59,339
so I was pondering this I think another

275
00:12:56,579 --> 00:13:01,500
year had gone past and over that course

276
00:12:59,339 --> 00:13:04,980
of that year I thought come on Raspberry

277
00:13:01,500 --> 00:13:05,639
pies must be able to do something so

278
00:13:04,980 --> 00:13:08,160
um

279
00:13:05,639 --> 00:13:13,320
I think I was in a Raspberry Pi phase

280
00:13:08,160 --> 00:13:14,399
so set out with a infrared Raspberry Pi

281
00:13:13,320 --> 00:13:17,839
camera

282
00:13:14,399 --> 00:13:17,839
down the bottom I think

283
00:13:19,260 --> 00:13:25,019
yep Raspberry Pi camera

284
00:13:21,980 --> 00:13:28,680
ds-18 B20 it's just a small temperature

285
00:13:25,019 --> 00:13:31,200
sensor very easy to use

286
00:13:28,680 --> 00:13:34,019
um two SLA batteries

287
00:13:31,200 --> 00:13:37,380
a sealed lead acid so they're about yay

288
00:13:34,019 --> 00:13:39,779
big very heavy unfortunately power

289
00:13:37,380 --> 00:13:42,120
distribution board so I the reason for

290
00:13:39,779 --> 00:13:46,440
that is the current how much current

291
00:13:42,120 --> 00:13:48,959
they this this rig uses so I could swap

292
00:13:46,440 --> 00:13:49,680
out batteries makes it very easy for

293
00:13:48,959 --> 00:13:51,600
that

294
00:13:49,680 --> 00:13:53,579
but I've still got to Lug them in to the

295
00:13:51,600 --> 00:13:54,260
forest

296
00:13:53,579 --> 00:13:56,940
um

297
00:13:54,260 --> 00:13:59,100
Electronics board yep so I made up my

298
00:13:56,940 --> 00:14:01,740
own board Etc real-time clock so I can

299
00:13:59,100 --> 00:14:06,180
do date typing of stamp uh stamping of

300
00:14:01,740 --> 00:14:10,440
data and infrared floodlight

301
00:14:06,180 --> 00:14:13,320
so started off uh with normal resolution

302
00:14:10,440 --> 00:14:14,880
but it was just taking too long to take

303
00:14:13,320 --> 00:14:18,240
a photograph

304
00:14:14,880 --> 00:14:20,639
relatively speaking and so I found by

305
00:14:18,240 --> 00:14:24,360
shrinking photographs down to 1920 by

306
00:14:20,639 --> 00:14:25,880
1080 I could get a photograph every 0.8

307
00:14:24,360 --> 00:14:28,860
of a second

308
00:14:25,880 --> 00:14:32,880
so you can see where the 3.2 million

309
00:14:28,860 --> 00:14:36,180
photographs might be coming in and yeah

310
00:14:32,880 --> 00:14:37,980
I was taking 87 to 100

311
00:14:36,180 --> 00:14:39,839
000 photos a day

312
00:14:37,980 --> 00:14:44,459
at that resolution

313
00:14:39,839 --> 00:14:48,120
and roughly a 30-day season and five

314
00:14:44,459 --> 00:14:50,240
different flowers monitored per season

315
00:14:48,120 --> 00:14:50,240
um

316
00:14:50,339 --> 00:14:56,279
so building equipment testing it out on

317
00:14:52,680 --> 00:14:58,019
a breadboard lots of fun and then on the

318
00:14:56,279 --> 00:15:00,120
left hand side there you can see the

319
00:14:58,019 --> 00:15:02,220
Barrow board moved everything onto a

320
00:15:00,120 --> 00:15:04,380
Vero board

321
00:15:02,220 --> 00:15:06,540
um with copious notes

322
00:15:04,380 --> 00:15:08,820
love making notes

323
00:15:06,540 --> 00:15:11,880
and that's how the rig looked just

324
00:15:08,820 --> 00:15:14,760
looking down on top of it I was just

325
00:15:11,880 --> 00:15:17,820
using it off the shelf for real-time

326
00:15:14,760 --> 00:15:20,339
camera board sorry real-time clock at

327
00:15:17,820 --> 00:15:23,940
that stage and various leads coming out

328
00:15:20,339 --> 00:15:27,000
not very waterproof at that stage

329
00:15:23,940 --> 00:15:29,339
later on I

330
00:15:27,000 --> 00:15:31,199
had learned a bit more about making my

331
00:15:29,339 --> 00:15:33,600
own printed circuit boards so I thought

332
00:15:31,199 --> 00:15:36,360
right this is fine I think one of the

333
00:15:33,600 --> 00:15:38,579
versions had failed you know changing

334
00:15:36,360 --> 00:15:41,100
batteries once a day in the middle of

335
00:15:38,579 --> 00:15:42,959
winter and in the dark because you're

336
00:15:41,100 --> 00:15:45,300
working and by the time you've driven

337
00:15:42,959 --> 00:15:47,820
there and walked into the forest it's

338
00:15:45,300 --> 00:15:49,500
now dark and it's raining and so you're

339
00:15:47,820 --> 00:15:51,720
trying to Shield everything with your

340
00:15:49,500 --> 00:15:54,000
Poncho and changing batteries water got

341
00:15:51,720 --> 00:15:57,720
in and eventually corroded the contacts

342
00:15:54,000 --> 00:16:00,660
but of everything but so making up a

343
00:15:57,720 --> 00:16:02,699
board was a real win

344
00:16:00,660 --> 00:16:04,940
and you can use it for other projects as

345
00:16:02,699 --> 00:16:04,940
well

346
00:16:05,279 --> 00:16:12,000
uh did some 3D printing for it all

347
00:16:09,120 --> 00:16:14,339
um sun shades camera sun shades flexible

348
00:16:12,000 --> 00:16:18,720
battery terminals Etc

349
00:16:14,339 --> 00:16:21,959
a lot of fun and also so how do you

350
00:16:18,720 --> 00:16:24,300
waterproof a Raspberry Pi camera housing

351
00:16:21,959 --> 00:16:26,760
so

352
00:16:24,300 --> 00:16:28,680
did it first in MDF to make sure it all

353
00:16:26,760 --> 00:16:30,959
fit and I think a couple of revisions

354
00:16:28,680 --> 00:16:34,320
that was interesting and then into

355
00:16:30,959 --> 00:16:37,019
acrylic and you'll see a hole there in

356
00:16:34,320 --> 00:16:40,620
in the center just to give a clear view

357
00:16:37,019 --> 00:16:41,420
through the uh the housing all glued

358
00:16:40,620 --> 00:16:45,360
together

359
00:16:41,420 --> 00:16:47,579
fantastic yep waterproof now hang on

360
00:16:45,360 --> 00:16:50,699
that's got a real I think it's uh

361
00:16:47,579 --> 00:16:53,339
infinite sort of uh the focus is like

362
00:16:50,699 --> 00:16:55,440
two meters away and the flower that I

363
00:16:53,339 --> 00:16:57,480
want is very tiny that's not going to be

364
00:16:55,440 --> 00:17:00,120
very good so

365
00:16:57,480 --> 00:17:03,540
um how do I focus luckily I'd cut a hole

366
00:17:00,120 --> 00:17:06,839
there so I could

367
00:17:03,540 --> 00:17:09,600
make up a 3D print this took a while but

368
00:17:06,839 --> 00:17:12,780
getting it through into there and break

369
00:17:09,600 --> 00:17:14,699
the lens the lenses glued into place so

370
00:17:12,780 --> 00:17:16,559
you've got to sit there and snap it and

371
00:17:14,699 --> 00:17:17,880
then rotate without destroying the

372
00:17:16,559 --> 00:17:21,179
camera

373
00:17:17,880 --> 00:17:23,040
but that all worked ended up with a

374
00:17:21,179 --> 00:17:25,319
distance of about six and a half

375
00:17:23,040 --> 00:17:26,880
centimeters

376
00:17:25,319 --> 00:17:30,419
Focus

377
00:17:26,880 --> 00:17:32,600
so there's the final rig we've now got

378
00:17:30,419 --> 00:17:35,600
waterproof glands

379
00:17:32,600 --> 00:17:40,740
waterproof USB

380
00:17:35,600 --> 00:17:43,440
plugs Etc HDMI and Power

381
00:17:40,740 --> 00:17:45,380
output

382
00:17:43,440 --> 00:17:50,340
that's what it looks like in the field

383
00:17:45,380 --> 00:17:52,500
uh just it's all pretty damp so laid

384
00:17:50,340 --> 00:17:55,260
everything out this is just for when I

385
00:17:52,500 --> 00:17:57,960
need to swap batteries

386
00:17:55,260 --> 00:18:00,000
Etc and make notes make some

387
00:17:57,960 --> 00:18:02,580
measurements and what have you

388
00:18:00,000 --> 00:18:03,960
and that's the final rig in the forest

389
00:18:02,580 --> 00:18:06,780
there

390
00:18:03,960 --> 00:18:08,940
so you can see at the base of one of

391
00:18:06,780 --> 00:18:11,400
those tree trunks

392
00:18:08,940 --> 00:18:13,919
it's focused you can just see a tiny

393
00:18:11,400 --> 00:18:16,080
little red dot there that's the flower

394
00:18:13,919 --> 00:18:19,140
and there might be maybe 10 different

395
00:18:16,080 --> 00:18:21,679
flowers around the tree stumped there or

396
00:18:19,140 --> 00:18:21,679
treat base

397
00:18:23,059 --> 00:18:26,820
camouflaged because people walk through

398
00:18:25,320 --> 00:18:29,039
the bush with their dog and what have

399
00:18:26,820 --> 00:18:33,419
you and there's maybe three four hundred

400
00:18:29,039 --> 00:18:35,460
dollars worth of equipment there so

401
00:18:33,419 --> 00:18:38,160
yep

402
00:18:35,460 --> 00:18:41,880
so um infrared

403
00:18:38,160 --> 00:18:45,780
Works day and night taking 0.8 of a

404
00:18:41,880 --> 00:18:47,760
second to take a photo and initially I

405
00:18:45,780 --> 00:18:49,980
went to AliExpress and bought one of

406
00:18:47,760 --> 00:18:52,200
those infrared floodlights never played

407
00:18:49,980 --> 00:18:54,600
with infrared before so I thought this

408
00:18:52,200 --> 00:18:57,900
should be fun and a lovely floodlight

409
00:18:54,600 --> 00:19:00,000
yes this works great in my room and put

410
00:18:57,900 --> 00:19:04,020
it out in the field about that distance

411
00:19:00,000 --> 00:19:05,760
away and it was just way too bright you

412
00:19:04,020 --> 00:19:07,919
know this is floodlight for looking at

413
00:19:05,760 --> 00:19:10,140
the back of the room sort of thing so I

414
00:19:07,919 --> 00:19:12,660
ended up with an extension cord and it's

415
00:19:10,140 --> 00:19:15,059
way over in another tree you know I

416
00:19:12,660 --> 00:19:17,820
thought no this is this is wrong so

417
00:19:15,059 --> 00:19:19,580
quickly whipped up a printed circuit

418
00:19:17,820 --> 00:19:22,460
board at home and

419
00:19:19,580 --> 00:19:27,020
soldered on some infrared floodlight

420
00:19:22,460 --> 00:19:30,720
infrared LEDs Works a treat

421
00:19:27,020 --> 00:19:35,900
but you can see here how close the

422
00:19:30,720 --> 00:19:35,900
camera is to the uh the flower there

423
00:19:39,240 --> 00:19:42,559
yep another shot

424
00:19:43,200 --> 00:19:49,160
and that's what it looks like during uh

425
00:19:46,380 --> 00:19:49,160
taking photograph

426
00:19:51,240 --> 00:19:56,660
date time stamp each

427
00:19:57,780 --> 00:20:05,660
no later on I date time stamp each

428
00:20:01,520 --> 00:20:05,660
photograph and the frame number

429
00:20:06,000 --> 00:20:11,340
um

430
00:20:07,200 --> 00:20:13,320
yep about 100 gigabytes of data a day

431
00:20:11,340 --> 00:20:15,539
so I've got to deal with that and this

432
00:20:13,320 --> 00:20:17,940
is what it looks like during the day you

433
00:20:15,539 --> 00:20:20,280
can see it's all a faded color and

434
00:20:17,940 --> 00:20:21,480
that's because of

435
00:20:20,280 --> 00:20:24,900
um

436
00:20:21,480 --> 00:20:26,820
that's because of the infrared and

437
00:20:24,900 --> 00:20:28,860
doesn't like color all that much but you

438
00:20:26,820 --> 00:20:31,700
can see an ant walking over the top of

439
00:20:28,860 --> 00:20:31,700
the flower there

440
00:20:32,100 --> 00:20:36,620
so

441
00:20:34,320 --> 00:20:40,980
um we're taking lots of photographs

442
00:20:36,620 --> 00:20:43,620
and which is good and then I need to use

443
00:20:40,980 --> 00:20:45,299
so how you know 100

444
00:20:43,620 --> 00:20:47,400
000 photos a day

445
00:20:45,299 --> 00:20:49,320
okay Paul there's only so many hours in

446
00:20:47,400 --> 00:20:51,539
a day to look at all of these and you've

447
00:20:49,320 --> 00:20:53,760
got to prep for tonight to take it out

448
00:20:51,539 --> 00:20:57,600
so how am I going to deal with that well

449
00:20:53,760 --> 00:20:59,460
opencv to the rescue and I should have

450
00:20:57,600 --> 00:21:04,200
noted the guy's name but there's an

451
00:20:59,460 --> 00:21:06,780
Adrian guy who was really big in opencv

452
00:21:04,200 --> 00:21:11,520
number of years ago and he's done some

453
00:21:06,780 --> 00:21:13,200
fantastic tutorials uh on opencv and got

454
00:21:11,520 --> 00:21:16,260
some lovely Play books on how to do

455
00:21:13,200 --> 00:21:18,660
things so mashing everything together

456
00:21:16,260 --> 00:21:22,980
um but there's some tricks you've got to

457
00:21:18,660 --> 00:21:25,500
learn to ignore the wind and winds

458
00:21:22,980 --> 00:21:30,360
fluttering some flowers so I'd set up

459
00:21:25,500 --> 00:21:34,200
some cyan boxes just to say ignore that

460
00:21:30,360 --> 00:21:37,980
opencv and the magenta is the areas of

461
00:21:34,200 --> 00:21:41,100
interest and so any movement of X number

462
00:21:37,980 --> 00:21:43,559
of pixel like a pixel range it's too big

463
00:21:41,100 --> 00:21:45,419
might be an air it might be a cockroach

464
00:21:43,559 --> 00:21:47,780
walking past or something to ignore that

465
00:21:45,419 --> 00:21:52,559
so it's just got to be the right size

466
00:21:47,780 --> 00:21:56,880
and if so then copy that photo into a

467
00:21:52,559 --> 00:22:01,020
subfolder so in the end I've only got to

468
00:21:56,880 --> 00:22:03,960
look at maybe 500 to 2000 photos a day

469
00:22:01,020 --> 00:22:08,280
and very easy just to flick through them

470
00:22:03,960 --> 00:22:12,059
so this is the basic file process so

471
00:22:08,280 --> 00:22:15,419
just carry over a USB stick every day

472
00:22:12,059 --> 00:22:18,559
I've got to go there and

473
00:22:15,419 --> 00:22:23,100
retrieve the stick put a new one in

474
00:22:18,559 --> 00:22:27,780
copy to my home NFS

475
00:22:23,100 --> 00:22:28,799
Nas store and then run a script which

476
00:22:27,780 --> 00:22:31,140
will

477
00:22:28,799 --> 00:22:34,080
every photo it takes is all logged into

478
00:22:31,140 --> 00:22:37,440
a log file so just use that log file to

479
00:22:34,080 --> 00:22:40,200
look at the date name of the the

480
00:22:37,440 --> 00:22:42,240
photograph and then annotate all that

481
00:22:40,200 --> 00:22:44,280
data onto the photograph so I've got

482
00:22:42,240 --> 00:22:45,440
some good meta data right there so

483
00:22:44,280 --> 00:22:50,220
visually

484
00:22:45,440 --> 00:22:55,320
and it also creates a 800 by 600 pixel

485
00:22:50,220 --> 00:22:57,179
copy of that file so opencv doesn't or

486
00:22:55,320 --> 00:22:58,799
it's just it can be really slow if

487
00:22:57,179 --> 00:23:02,039
you're playing with large files so it's

488
00:22:58,799 --> 00:23:02,940
just good shrink it down and

489
00:23:02,039 --> 00:23:06,500
um

490
00:23:02,940 --> 00:23:11,100
yep and then turn all of those using

491
00:23:06,500 --> 00:23:13,679
ffmpeg turn all of those into a movie

492
00:23:11,100 --> 00:23:16,140
so I've got a nice movie at all and then

493
00:23:13,679 --> 00:23:18,360
use opencv and motion detection to

494
00:23:16,140 --> 00:23:20,940
detect what's going on in that magenta

495
00:23:18,360 --> 00:23:22,980
box there and if it files things as I

496
00:23:20,940 --> 00:23:25,799
said copy the photos into a separate

497
00:23:22,980 --> 00:23:29,299
directory and log all of the findings

498
00:23:25,799 --> 00:23:29,299
into a CSV file

499
00:23:31,380 --> 00:23:38,640
so here's some results a uh ant climbing

500
00:23:36,539 --> 00:23:40,320
out of a flower

501
00:23:38,640 --> 00:23:43,919
it's interesting one thing I've noticed

502
00:23:40,320 --> 00:23:46,980
is that there seems to be some sort of

503
00:23:43,919 --> 00:23:49,860
glands on either side of the base inside

504
00:23:46,980 --> 00:23:51,780
the flower just here and here seems to

505
00:23:49,860 --> 00:23:54,299
be some sort of glands the ants like to

506
00:23:51,780 --> 00:23:57,600
go there and just do something there

507
00:23:54,299 --> 00:23:59,600
so um we've got some further research to

508
00:23:57,600 --> 00:24:04,820
do on that

509
00:23:59,600 --> 00:24:04,820
some Daytime Nighttime shots flowers

510
00:24:05,100 --> 00:24:10,400
this one's interesting so opencv pulled

511
00:24:09,000 --> 00:24:12,240
something up

512
00:24:10,400 --> 00:24:14,220
and

513
00:24:12,240 --> 00:24:17,100
and you think oh yeah yeah there it is

514
00:24:14,220 --> 00:24:20,039
then after a while you've oh look at

515
00:24:17,100 --> 00:24:24,360
that a crane fly had just perched there

516
00:24:20,039 --> 00:24:27,360
and it sat there for hours upon hours

517
00:24:24,360 --> 00:24:30,600
so that's maybe a fruit fly

518
00:24:27,360 --> 00:24:33,419
and then over here maybe a predatory

519
00:24:30,600 --> 00:24:37,559
wasp

520
00:24:33,419 --> 00:24:41,059
very tiny we're talking uh maybe a

521
00:24:37,559 --> 00:24:41,059
couple of millimeters maximum

522
00:24:41,299 --> 00:24:47,700
and so now we're looking down inside and

523
00:24:45,360 --> 00:24:49,799
a fruit fly is just about to go down

524
00:24:47,700 --> 00:24:51,919
inside

525
00:24:49,799 --> 00:24:51,919
um

526
00:24:53,400 --> 00:24:57,900
and so this is the to show you the size

527
00:24:55,740 --> 00:25:01,080
of that

528
00:24:57,900 --> 00:25:04,260
so this here is the camera the sun shade

529
00:25:01,080 --> 00:25:06,360
the weathershade on the camera lens so

530
00:25:04,260 --> 00:25:08,280
the Raspberry Pi camera is this big the

531
00:25:06,360 --> 00:25:10,799
housings may be this big there's the

532
00:25:08,280 --> 00:25:12,960
housing and it's just looking down this

533
00:25:10,799 --> 00:25:17,460
tiny tiny little flower and you're

534
00:25:12,960 --> 00:25:19,500
looking down inside and there's the

535
00:25:17,460 --> 00:25:22,860
the fly

536
00:25:19,500 --> 00:25:26,640
so results over

537
00:25:22,860 --> 00:25:30,120
a couple of Seasons two Bush flies for

538
00:25:26,640 --> 00:25:32,400
seven to 36 seconds

539
00:25:30,120 --> 00:25:33,720
um 36 seconds seems like a long time

540
00:25:32,400 --> 00:25:37,500
inside I don't know what they're doing

541
00:25:33,720 --> 00:25:42,000
down there but seven brown ants going in

542
00:25:37,500 --> 00:25:45,360
for five to six seconds each and some

543
00:25:42,000 --> 00:25:47,159
fungus gnats for 13 to 20 seconds and

544
00:25:45,360 --> 00:25:49,500
the thinking was at the time that would

545
00:25:47,159 --> 00:25:53,159
be fungus gnats so it was interesting to

546
00:25:49,500 --> 00:25:56,340
see so many ants going down inside there

547
00:25:53,159 --> 00:25:59,940
but I've yet to still uh it's been

548
00:25:56,340 --> 00:26:02,340
unfortunate with uh personal life Etc

549
00:25:59,940 --> 00:26:04,919
we've I've missed a number of years but

550
00:26:02,340 --> 00:26:07,640
we'll be back at it this year

551
00:26:04,919 --> 00:26:10,620
but there's lots of interesting things

552
00:26:07,640 --> 00:26:12,360
so when you set the camera up you know

553
00:26:10,620 --> 00:26:14,720
you're looking there you're spending a

554
00:26:12,360 --> 00:26:17,460
bit of time there and you see nothing

555
00:26:14,720 --> 00:26:19,440
it's just Barren you think oh this is

556
00:26:17,460 --> 00:26:22,380
pretty boring

557
00:26:19,440 --> 00:26:25,440
um but as soon as you leave within about

558
00:26:22,380 --> 00:26:29,159
five minutes everything just comes to

559
00:26:25,440 --> 00:26:33,120
life it is fascinating the the insects

560
00:26:29,159 --> 00:26:37,520
the worms uh the mites that are all

561
00:26:33,120 --> 00:26:37,520
crawling around it's yeah

562
00:26:38,100 --> 00:26:45,299
so there we've got a spider in the top

563
00:26:41,760 --> 00:26:47,580
left we've got a tick in the top right

564
00:26:45,299 --> 00:26:49,620
I've never had a tick on me that's been

565
00:26:47,580 --> 00:26:52,039
interesting don't know what that thing

566
00:26:49,620 --> 00:26:54,900
is in the bottom right and then a

567
00:26:52,039 --> 00:26:57,480
cockroach nymph or something crawling

568
00:26:54,900 --> 00:27:00,900
around lots of spiders and you just see

569
00:26:57,480 --> 00:27:02,520
these big like up uh horror movie or

570
00:27:00,900 --> 00:27:04,080
something there's a big thing walking

571
00:27:02,520 --> 00:27:07,220
longer

572
00:27:04,080 --> 00:27:07,220
when you look at the video

573
00:27:08,279 --> 00:27:14,039
so I love collecting data so uh yep

574
00:27:11,700 --> 00:27:14,580
let's see how the batteries are going

575
00:27:14,039 --> 00:27:18,120
um

576
00:27:14,580 --> 00:27:20,580
current usage the Reds the current on

577
00:27:18,120 --> 00:27:21,840
the right hand side there and you can

578
00:27:20,580 --> 00:27:24,900
see

579
00:27:21,840 --> 00:27:28,559
um night time versus daytime the current

580
00:27:24,900 --> 00:27:30,860
because the uh using the infrared flood

581
00:27:28,559 --> 00:27:34,200
lights turning on Etc

582
00:27:30,860 --> 00:27:37,320
I love using gnu plot I've used it for

583
00:27:34,200 --> 00:27:39,120
some other projects and it is just so

584
00:27:37,320 --> 00:27:42,000
fast you know you're doing million

585
00:27:39,120 --> 00:27:44,700
points of data and it's just boom done

586
00:27:42,000 --> 00:27:47,100
so yep

587
00:27:44,700 --> 00:27:50,220
and also you've got a lots of rabbit

588
00:27:47,100 --> 00:27:52,740
Warrens you can go down for projects as

589
00:27:50,220 --> 00:27:54,980
per usual and so I decided to build

590
00:27:52,740 --> 00:27:58,940
myself a little Raspberry Pi based

591
00:27:54,980 --> 00:28:01,620
battery profiling rig just dumping data

592
00:27:58,940 --> 00:28:04,020
just dumping power into the Big Green

593
00:28:01,620 --> 00:28:06,600
resistors on the right hand side just a

594
00:28:04,020 --> 00:28:08,880
profile of batteries they were just to

595
00:28:06,600 --> 00:28:12,299
see how they ran whether they'd run the

596
00:28:08,880 --> 00:28:15,200
time Etc I was pretty happy with it all

597
00:28:12,299 --> 00:28:19,440
yeah run times

598
00:28:15,200 --> 00:28:22,500
uh temperatures logging all of that I

599
00:28:19,440 --> 00:28:25,440
haven't really sat there yet to my

600
00:28:22,500 --> 00:28:28,919
thinking was it'd be interesting

601
00:28:25,440 --> 00:28:32,580
um trying to profile maybe insect

602
00:28:28,919 --> 00:28:34,679
movement uh how active things were with

603
00:28:32,580 --> 00:28:37,080
temperature

604
00:28:34,679 --> 00:28:40,140
um and also the course of the season so

605
00:28:37,080 --> 00:28:41,700
we're running July through August so

606
00:28:40,140 --> 00:28:43,620
just you know over the course of

607
00:28:41,700 --> 00:28:47,640
temperature the things wake up or do

608
00:28:43,620 --> 00:28:50,460
they go away and while writing this I

609
00:28:47,640 --> 00:28:54,720
was thinking oh it'd be kind of I never

610
00:28:50,460 --> 00:28:57,299
really logged uh uh rainfall and so it'd

611
00:28:54,720 --> 00:28:59,340
be interesting logging insect movements

612
00:28:57,299 --> 00:29:02,220
around rainfall patterns and how damp

613
00:28:59,340 --> 00:29:04,559
things are there so that's another

614
00:29:02,220 --> 00:29:07,220
Improvement that will come up maybe uh

615
00:29:04,559 --> 00:29:07,220
this year

616
00:29:07,380 --> 00:29:15,179
yep

617
00:29:09,779 --> 00:29:19,919
oh and I was happy that inside the Box

618
00:29:15,179 --> 00:29:21,779
where do we go CPU temperature CPU 48

619
00:29:19,919 --> 00:29:23,159
degrees or something like that I thought

620
00:29:21,779 --> 00:29:26,399
that's pretty cool

621
00:29:23,159 --> 00:29:28,380
inside a sealed container oh one thing

622
00:29:26,399 --> 00:29:33,960
about that container so here I was

623
00:29:28,380 --> 00:29:38,299
paranoid about water getting in and uh

624
00:29:33,960 --> 00:29:42,720
that wasn't the issue the issue was ants

625
00:29:38,299 --> 00:29:45,120
they love a dry place and I tell you the

626
00:29:42,720 --> 00:29:46,980
number of hours I spent trying to make

627
00:29:45,120 --> 00:29:48,240
that damn thing and proof it was

628
00:29:46,980 --> 00:29:50,820
waterproof

629
00:29:48,240 --> 00:29:53,100
but there's a lid you know that the lid

630
00:29:50,820 --> 00:29:55,440
sits on like that so here's the base and

631
00:29:53,100 --> 00:29:57,600
the lid sits over just trying to get

632
00:29:55,440 --> 00:30:01,860
that seal around they're all ant proof

633
00:29:57,600 --> 00:30:03,960
it was oh you'd be patching but visually

634
00:30:01,860 --> 00:30:05,399
it looks fine but obviously not ants are

635
00:30:03,960 --> 00:30:07,919
getting in

636
00:30:05,399 --> 00:30:13,500
so anyway good laugh

637
00:30:07,919 --> 00:30:16,140
um so 2016 I couldn't afford uh a bit of

638
00:30:13,500 --> 00:30:19,679
context I couldn't afford a 128 gig

639
00:30:16,140 --> 00:30:22,860
flash drive so I started off with 64 and

640
00:30:19,679 --> 00:30:26,520
gigabyte and quickly found out that my

641
00:30:22,860 --> 00:30:29,399
data was space was all being used up so

642
00:30:26,520 --> 00:30:31,799
oops so that year didn't get much data

643
00:30:29,399 --> 00:30:33,299
you know there's big gaps in my data but

644
00:30:31,799 --> 00:30:36,120
luckily the following year I could

645
00:30:33,299 --> 00:30:40,020
afford the 120 or something like that

646
00:30:36,120 --> 00:30:42,260
for a 128 gigabyte flash drive so all

647
00:30:40,020 --> 00:30:42,260
good

648
00:30:43,020 --> 00:30:49,080
oh and one of the other intro I will

649
00:30:46,500 --> 00:30:51,360
talk about on this page so some project

650
00:30:49,080 --> 00:30:54,240
issues was

651
00:30:51,360 --> 00:30:58,080
um yep so I've got a nice folder there

652
00:30:54,240 --> 00:31:00,840
and I'm just sticking files in and uh it

653
00:30:58,080 --> 00:31:02,700
just kept topping out at 16 000 and I'm

654
00:31:00,840 --> 00:31:04,500
trying all these things and you know

655
00:31:02,700 --> 00:31:06,659
you'd have to wait a day to see whether

656
00:31:04,500 --> 00:31:09,960
it happened or I didn't bother just

657
00:31:06,659 --> 00:31:14,460
dumping data in there but uh at home but

658
00:31:09,960 --> 00:31:16,620
uh yep eventually found uh was it FAT32

659
00:31:14,460 --> 00:31:21,179
is not your friend for this

660
00:31:16,620 --> 00:31:24,500
so yep good one

661
00:31:21,179 --> 00:31:29,340
um and then dealing yep and

662
00:31:24,500 --> 00:31:31,799
108 gigabytes up to 180 108 gigabytes of

663
00:31:29,340 --> 00:31:34,559
data per day that was interesting just

664
00:31:31,799 --> 00:31:36,480
the time length and transferring files

665
00:31:34,559 --> 00:31:38,520
back and forth

666
00:31:36,480 --> 00:31:40,640
Etc running all the scripts some hours

667
00:31:38,520 --> 00:31:43,320
would go past

668
00:31:40,640 --> 00:31:46,799
uh yep

669
00:31:43,320 --> 00:31:50,340
ah there was another one deleting

670
00:31:46,799 --> 00:31:54,960
85 to 100 000 files in the directory you

671
00:31:50,340 --> 00:31:57,659
just can't run RM space asterisks takes

672
00:31:54,960 --> 00:32:00,720
way too like well it just comes up I

673
00:31:57,659 --> 00:32:04,620
think it errors out so I found the left

674
00:32:00,720 --> 00:32:06,419
hand command there works really well uh

675
00:32:04,620 --> 00:32:08,899
or just

676
00:32:06,419 --> 00:32:12,419
reformat the drive

677
00:32:08,899 --> 00:32:14,039
battery power is an issue but now

678
00:32:12,419 --> 00:32:17,279
lithium batteries have come on the

679
00:32:14,039 --> 00:32:19,520
market so a lot more the at an expense

680
00:32:17,279 --> 00:32:19,520
though

681
00:32:19,740 --> 00:32:26,279
yep so out of all of that

682
00:32:23,340 --> 00:32:30,299
um I got asked to go to Shenzhen

683
00:32:26,279 --> 00:32:34,200
and give a talk and a bit about the

684
00:32:30,299 --> 00:32:37,200
project and so and have a display there

685
00:32:34,200 --> 00:32:39,600
so I love maker fares and this is the

686
00:32:37,200 --> 00:32:41,640
only one I've been to but oh the only

687
00:32:39,600 --> 00:32:44,840
place I've been to I've been there many

688
00:32:41,640 --> 00:32:48,240
times but it was really interesting

689
00:32:44,840 --> 00:32:52,559
seeing people's reactions to the setup

690
00:32:48,240 --> 00:32:54,840
there and Shenzhen is also known as her

691
00:32:52,559 --> 00:32:57,840
place where people like to copy things

692
00:32:54,840 --> 00:32:57,840
and

693
00:32:58,140 --> 00:33:02,520
yeah it's all business business and so

694
00:33:01,080 --> 00:33:04,260
you're at a Maker Faire which is meant

695
00:33:02,520 --> 00:33:07,260
to be friendly and open and what have

696
00:33:04,260 --> 00:33:09,240
you and this guy's walking up with this

697
00:33:07,260 --> 00:33:11,700
big huge lens photographing everything

698
00:33:09,240 --> 00:33:14,820
like this and I'm going go for it dude

699
00:33:11,700 --> 00:33:16,440
no worries you can take it take it I'll

700
00:33:14,820 --> 00:33:17,880
give you the design if you wanted you

701
00:33:16,440 --> 00:33:21,840
know it's no big deal

702
00:33:17,880 --> 00:33:24,059
and another guy pestering me said that

703
00:33:21,840 --> 00:33:26,940
rig is fantastic you could turn that

704
00:33:24,059 --> 00:33:29,159
into a toy you know for a kid's toy or

705
00:33:26,940 --> 00:33:31,380
something infrared photography what sort

706
00:33:29,159 --> 00:33:33,539
of things you want to do with that and

707
00:33:31,380 --> 00:33:34,500
uh yeah yeah that was going too far I

708
00:33:33,539 --> 00:33:37,140
thought

709
00:33:34,500 --> 00:33:41,460
but we had 50 000 people walk past over

710
00:33:37,140 --> 00:33:43,880
a three-day period uh lots of fun

711
00:33:41,460 --> 00:33:47,760
um my wife was there in the back there

712
00:33:43,880 --> 00:33:53,039
and I'll just divert a little bit here

713
00:33:47,760 --> 00:33:55,620
but it was interesting her she had on

714
00:33:53,039 --> 00:33:57,240
her table she was doing she's wondering

715
00:33:55,620 --> 00:33:59,760
oh what am I going to do there you know

716
00:33:57,240 --> 00:34:01,320
am I going to sit three days waiting for

717
00:33:59,760 --> 00:34:04,380
you so I said no no bring something

718
00:34:01,320 --> 00:34:07,200
along so she brought along some fabric

719
00:34:04,380 --> 00:34:10,379
squares about yay big she's into Fabric

720
00:34:07,200 --> 00:34:14,280
and quilting and she brought along some

721
00:34:10,379 --> 00:34:17,820
cruelters pens and had people writing so

722
00:34:14,280 --> 00:34:20,520
people could write draw pictures poems

723
00:34:17,820 --> 00:34:22,379
whatever you like on those squares

724
00:34:20,520 --> 00:34:25,379
and um

725
00:34:22,379 --> 00:34:28,560
there we are oh and she's doing LEDs in

726
00:34:25,379 --> 00:34:31,980
dresses and things like that hat there's

727
00:34:28,560 --> 00:34:35,040
a hat there with LEDs going going off

728
00:34:31,980 --> 00:34:36,780
lots of fun 50 000 people three days you

729
00:34:35,040 --> 00:34:39,839
just horse at the end of the day

730
00:34:36,780 --> 00:34:42,619
or at the end of the three days and see

731
00:34:39,839 --> 00:34:47,639
see some of the blocks there framed off

732
00:34:42,619 --> 00:34:51,899
and uh met many many people and so we

733
00:34:47,639 --> 00:34:54,480
got 650 of those blocks

734
00:34:51,899 --> 00:34:56,879
um and I thought this is some of them

735
00:34:54,480 --> 00:35:00,240
are really interesting stories so

736
00:34:56,879 --> 00:35:03,839
another rabbit uh hole to go down I

737
00:35:00,240 --> 00:35:05,280
built a as one does I built a my own

738
00:35:03,839 --> 00:35:09,660
home scanner

739
00:35:05,280 --> 00:35:11,640
for it and lots of fun trying to get the

740
00:35:09,660 --> 00:35:13,859
angles you can see the aluminum bars

741
00:35:11,640 --> 00:35:16,500
there they're the lighting and just

742
00:35:13,859 --> 00:35:18,240
trying to get that the right angle so it

743
00:35:16,500 --> 00:35:20,160
doesn't reflect back up to the Raspberry

744
00:35:18,240 --> 00:35:23,940
Pi camera on the top there

745
00:35:20,160 --> 00:35:26,760
uh you can see a Raspberry Pi display at

746
00:35:23,940 --> 00:35:29,040
the end there and that's just showing

747
00:35:26,760 --> 00:35:32,040
the making sure everything's okay but

748
00:35:29,040 --> 00:35:33,900
you close the lid and micro switch the

749
00:35:32,040 --> 00:35:35,940
light flood lights come on takes a

750
00:35:33,900 --> 00:35:37,440
photograph and then goes off and you

751
00:35:35,940 --> 00:35:39,119
know you can lift it up and put the next

752
00:35:37,440 --> 00:35:42,780
block there

753
00:35:39,119 --> 00:35:47,220
so lots of fun and then of course opencv

754
00:35:42,780 --> 00:35:50,520
to the rescue uh uh it would extract the

755
00:35:47,220 --> 00:35:53,460
image find the edges and then auto

756
00:35:50,520 --> 00:35:55,740
rotate that was a nice little Nifty

757
00:35:53,460 --> 00:35:57,780
feature so we've got all that digitized

758
00:35:55,740 --> 00:35:59,579
and one day we'd like to maybe put that

759
00:35:57,780 --> 00:36:01,800
online or something like that just to

760
00:35:59,579 --> 00:36:03,500
show people with some lovely stories I

761
00:36:01,800 --> 00:36:06,240
think

762
00:36:03,500 --> 00:36:09,839
two years of sewing to put it all

763
00:36:06,240 --> 00:36:11,700
together and she's doing the Makey robot

764
00:36:09,839 --> 00:36:12,480
there

765
00:36:11,700 --> 00:36:16,980
um

766
00:36:12,480 --> 00:36:20,040
and it ended up to be four meters by

767
00:36:16,980 --> 00:36:24,140
four and a half meters in size so in

768
00:36:20,040 --> 00:36:28,020
2019 we went back to the make Affair and

769
00:36:24,140 --> 00:36:31,520
they put it up there and to make of the

770
00:36:28,020 --> 00:36:34,440
Shenzhen maker fair is

771
00:36:31,520 --> 00:36:39,480
posted or the main sponsor if you like

772
00:36:34,440 --> 00:36:41,820
is the seed s Triple E D Electronics

773
00:36:39,480 --> 00:36:45,240
making small little hobbyist making

774
00:36:41,820 --> 00:36:49,079
company and that's uh being on the right

775
00:36:45,240 --> 00:36:52,740
hand side there who's the CEO of the

776
00:36:49,079 --> 00:36:56,040
company and uh yeah lots of fun and it

777
00:36:52,740 --> 00:36:56,880
was donated to the Shenzhen maker fit

778
00:36:56,040 --> 00:36:58,380
there

779
00:36:56,880 --> 00:37:01,020
so I think they've hung it up in their

780
00:36:58,380 --> 00:37:03,140
boardroom or something

781
00:37:01,020 --> 00:37:03,140
um

782
00:37:03,359 --> 00:37:05,900
yeah

783
00:37:06,660 --> 00:37:11,900
so

784
00:37:07,980 --> 00:37:15,720
that's my talk

785
00:37:11,900 --> 00:37:19,980
all the project information's online

786
00:37:15,720 --> 00:37:22,740
um the thingiverse files are up there

787
00:37:19,980 --> 00:37:26,460
Etc and a bit more information about the

788
00:37:22,740 --> 00:37:29,300
orchids and fungus gnats Etc

789
00:37:26,460 --> 00:37:29,300
thank you very much

790
00:37:32,030 --> 00:37:36,540
[Applause]

791
00:37:33,900 --> 00:37:38,460
if there are any questions yep we got

792
00:37:36,540 --> 00:37:41,180
about five minutes

793
00:37:38,460 --> 00:37:41,180
any questions

794
00:37:43,140 --> 00:37:47,280
thanks for the talk Paul

795
00:37:45,720 --> 00:37:48,900
um would it be possible to do some of

796
00:37:47,280 --> 00:37:51,300
the filtering in the Raspberry Pi as you

797
00:37:48,900 --> 00:37:52,440
capture the pictures either directly

798
00:37:51,300 --> 00:37:53,339
with another Raspberry Pi doing the

799
00:37:52,440 --> 00:37:55,440
words it looks like that one's been

800
00:37:53,339 --> 00:37:59,880
overloaded

801
00:37:55,440 --> 00:38:02,220
yes back in the day when I kicked this

802
00:37:59,880 --> 00:38:04,380
off it was just the beginning of machine

803
00:38:02,220 --> 00:38:07,200
learning well not the beginning but at

804
00:38:04,380 --> 00:38:08,339
least in our in the hobbyist world

805
00:38:07,200 --> 00:38:10,680
um

806
00:38:08,339 --> 00:38:12,660
there there was no I don't think there

807
00:38:10,680 --> 00:38:16,260
was any uh now you can get a little

808
00:38:12,660 --> 00:38:19,140
plug-in boards uh for uh neural you know

809
00:38:16,260 --> 00:38:21,780
processing Etc

810
00:38:19,140 --> 00:38:24,359
there's not really that you know maybe

811
00:38:21,780 --> 00:38:25,859
on a second one but uh it's a lot of

812
00:38:24,359 --> 00:38:29,099
data and then you'd have to somehow

813
00:38:25,859 --> 00:38:30,980
share the data between the two and I was

814
00:38:29,099 --> 00:38:33,660
I didn't know what to expect

815
00:38:30,980 --> 00:38:35,820
so my understanding of machine learning

816
00:38:33,660 --> 00:38:39,119
at the time was you needed to have a

817
00:38:35,820 --> 00:38:42,359
data set of images to say what you

818
00:38:39,119 --> 00:38:45,720
wanted to see and I didn't know what I

819
00:38:42,359 --> 00:38:47,720
was what sort of insects or ants or what

820
00:38:45,720 --> 00:38:50,880
sort of things were going inside

821
00:38:47,720 --> 00:38:53,280
yeah so I thought I'd play safe just

822
00:38:50,880 --> 00:38:56,760
collect all the data it ended up so far

823
00:38:53,280 --> 00:38:58,800
it's 2.7 terabytes of data so you know

824
00:38:56,760 --> 00:39:00,420
people saying oh just send it off over

825
00:38:58,800 --> 00:39:03,500
the internet you know and I'm going

826
00:39:00,420 --> 00:39:08,880
right I'm out in the forest no

827
00:39:03,500 --> 00:39:11,940
and uh yeah reception is poor and

828
00:39:08,880 --> 00:39:16,500
um and I don't have a 2.7 terabyte data

829
00:39:11,940 --> 00:39:18,060
plan so yeah the point was that you just

830
00:39:16,500 --> 00:39:20,579
use the standard version section they

831
00:39:18,060 --> 00:39:26,119
use for security cameras yep at least

832
00:39:20,579 --> 00:39:26,119
the first cut yes yeah yep yep yep

833
00:39:26,520 --> 00:39:30,420
um thank you Paul

834
00:39:28,200 --> 00:39:32,520
um and favorite part of the story is how

835
00:39:30,420 --> 00:39:34,260
you were so spectacularly nerd sniped by

836
00:39:32,520 --> 00:39:35,760
your friend at the the professor at the

837
00:39:34,260 --> 00:39:37,440
beginning I'd love to know what they

838
00:39:35,760 --> 00:39:40,859
think about all this and and people in

839
00:39:37,440 --> 00:39:42,060
there in their field is this is this the

840
00:39:40,859 --> 00:39:44,280
most incredible thing they've ever seen

841
00:39:42,060 --> 00:39:46,320
and they want you to do every other type

842
00:39:44,280 --> 00:39:48,720
of species of orchid or

843
00:39:46,320 --> 00:39:52,140
um or is this a regular thing that they

844
00:39:48,720 --> 00:39:53,460
do yeah uh thank you

845
00:39:52,140 --> 00:39:56,760
um

846
00:39:53,460 --> 00:39:59,460
it's the weirdest I think but uh there's

847
00:39:56,760 --> 00:40:01,800
people photographers who sit uh there's

848
00:39:59,460 --> 00:40:03,480
a Victorian guy actually and he's done a

849
00:40:01,800 --> 00:40:04,140
number of books

850
00:40:03,480 --> 00:40:06,599
um

851
00:40:04,140 --> 00:40:08,940
he has

852
00:40:06,599 --> 00:40:10,859
lots of patients more patience than me

853
00:40:08,940 --> 00:40:13,079
sitting out in the forest and with

854
00:40:10,859 --> 00:40:14,520
mosquitoes buzzing around and ticks and

855
00:40:13,079 --> 00:40:18,000
what have you

856
00:40:14,520 --> 00:40:18,839
um he's done some lovely camera work

857
00:40:18,000 --> 00:40:22,320
um

858
00:40:18,839 --> 00:40:25,560
I was fortunate that this flower is

859
00:40:22,320 --> 00:40:27,240
doesn't move you know it just sits there

860
00:40:25,560 --> 00:40:29,220
um whereas you get the other spider

861
00:40:27,240 --> 00:40:31,380
orchids and things like that and the

862
00:40:29,220 --> 00:40:33,780
moving around so you think you'd have to

863
00:40:31,380 --> 00:40:35,280
clamp some of the others

864
00:40:33,780 --> 00:40:38,940
um I have

865
00:40:35,280 --> 00:40:41,160
yeah I've had a go but the photographs

866
00:40:38,940 --> 00:40:44,160
weren't all that crash hot you know I

867
00:40:41,160 --> 00:40:47,940
think you'd have to clamp it somehow one

868
00:40:44,160 --> 00:40:51,960
of the the issues or that I've got is

869
00:40:47,940 --> 00:40:54,780
the cameras very close to the flower so

870
00:40:51,960 --> 00:40:55,980
I wonder whether that is influencing

871
00:40:54,780 --> 00:40:59,040
things

872
00:40:55,980 --> 00:41:01,320
so yeah yeah maybe

873
00:40:59,040 --> 00:41:02,700
um well now that uh Raspberry Pi

874
00:41:01,320 --> 00:41:03,720
Foundation have come out with some other

875
00:41:02,700 --> 00:41:07,079
cameras and you can buy other

876
00:41:03,720 --> 00:41:09,540
third-party cameras that have zoom lens

877
00:41:07,079 --> 00:41:12,359
Etc so it might be worth to try some of

878
00:41:09,540 --> 00:41:14,099
those and they're not that expensive

879
00:41:12,359 --> 00:41:16,700
get further back

880
00:41:14,099 --> 00:41:16,700
hmm

881
00:41:26,160 --> 00:41:30,060
um I think you're in the audience for

882
00:41:27,660 --> 00:41:31,079
this talk yesterday from Dr mcgiver

883
00:41:30,060 --> 00:41:33,660
about

884
00:41:31,079 --> 00:41:35,880
giving students access to data about

885
00:41:33,660 --> 00:41:38,579
giving students access to data sets to

886
00:41:35,880 --> 00:41:40,320
do yeah a wonderful talk yes as well can

887
00:41:38,579 --> 00:41:42,900
you imagine some sort of subset of this

888
00:41:40,320 --> 00:41:46,200
that you could slurp her way and and

889
00:41:42,900 --> 00:41:47,099
imagine students finding other things it

890
00:41:46,200 --> 00:41:49,980
was really interesting things about the

891
00:41:47,099 --> 00:41:52,079
temperatures yeah yes yeah yeah I've

892
00:41:49,980 --> 00:41:53,880
wondered about that

893
00:41:52,079 --> 00:41:56,880
um but

894
00:41:53,880 --> 00:42:01,200
I haven't talked to anyone but it's

895
00:41:56,880 --> 00:42:04,619
where do you store 2.7 terabytes worth

896
00:42:01,200 --> 00:42:07,560
of files that's the issue I've got but

897
00:42:04,619 --> 00:42:10,380
yeah I mean I'd love to it's open to

898
00:42:07,560 --> 00:42:12,300
anyone if they want to play with it

899
00:42:10,380 --> 00:42:16,220
hmm

900
00:42:12,300 --> 00:42:16,220
if you know of anyone let me know

901
00:42:16,440 --> 00:42:21,660
yep

902
00:42:18,839 --> 00:42:23,700
okay thank you once again all right okay

903
00:42:21,660 --> 00:42:26,520
thank you yep

904
00:42:23,700 --> 00:42:29,599
do have a small gift

905
00:42:26,520 --> 00:42:29,599
thank you

906
00:42:31,070 --> 00:42:34,760
[Applause]
