1
00:00:03,720 --> 00:00:05,280
Okay, guys.

2
00:00:07,000 --> 00:00:14,140
But we will start the next presentation, which is called This Year's Village Badge.

3
00:00:14,320 --> 00:00:20,960
My name is Michael Schloff von Benevitz, and I believe that our AV is working very well.

4
00:00:20,960 --> 00:00:25,140
Thanks so much to SGP and to AGS.

5
00:00:25,440 --> 00:00:29,000
And let me just get started with this.

6
00:00:29,000 --> 00:00:33,660
We have some interesting devices to take a look at.

7
00:00:36,700 --> 00:00:39,100
To begin with, we have...

8
00:00:41,640 --> 00:00:46,380
To begin with, I should turn off my stream so there's no echo.

9
00:00:46,380 --> 00:00:47,500
Okay, that's better.

10
00:00:48,680 --> 00:00:55,000
So this is the high-tech slide deck that you may have heard of with the paper and the pencil.

11
00:00:55,040 --> 00:00:56,980
That's how we're doing it this year.

12
00:00:56,980 --> 00:01:00,020
This year's Village Badge.

13
00:01:08,640 --> 00:01:12,920
And what we have here, we've got basically three days.

14
00:01:13,080 --> 00:01:14,400
We've got Friday.

15
00:01:14,460 --> 00:01:16,040
We've got Saturday.

16
00:01:18,140 --> 00:01:19,860
Let me do this.

17
00:01:20,200 --> 00:01:23,360
We've got Friday, we've got Saturday, and we've got Sunday.

18
00:01:23,900 --> 00:01:27,540
So this is where we are.

19
00:01:27,820 --> 00:01:32,300
And I'm just explaining this because there's a little bit of organization.

20
00:01:32,300 --> 00:01:37,080
Some people are interested in beginner style, novice topics.

21
00:01:37,080 --> 00:01:40,000
Others are into the more advanced stuff.

22
00:01:40,000 --> 00:01:44,600
So we've got this presentation now.

23
00:01:44,740 --> 00:01:48,060
Later, we've got another one.

24
00:01:48,060 --> 00:01:50,900
It's called Getting Started.

25
00:01:55,030 --> 00:02:00,970
Okay, and in this one, we're going to talk about the construction,

26
00:02:06,390 --> 00:02:08,290
how it's made.

27
00:02:10,570 --> 00:02:14,770
A lot of people have been asking about, can they make it on their own?

28
00:02:14,770 --> 00:02:16,030
Is it open source?

29
00:02:16,030 --> 00:02:17,470
Are there design archives?

30
00:02:17,470 --> 00:02:18,750
This type of thing.

31
00:02:19,250 --> 00:02:23,870
So that's what we're going to do now on Friday in this first hour.

32
00:02:23,870 --> 00:02:33,830
Okay, so we're going to talk about the SCM, the source code management, the open source, all of the things that you can store on disk, like the design archives.

33
00:02:34,430 --> 00:02:43,030
And after this hour is over, we'll take a short break and we'll have another presentation with me as well.

34
00:02:43,030 --> 00:02:46,170
Just like Rira said before, this is the Michael evening.

35
00:02:46,390 --> 00:02:49,230
And we will talk about getting started with the badge.

36
00:02:49,230 --> 00:02:56,450
So this second hour, this will be things like, what is the first thing that I can do once I have it in my hands?

37
00:02:57,190 --> 00:02:58,470
This is the way it looks.

38
00:02:58,470 --> 00:03:00,310
So let me just put that on the side.

39
00:03:01,110 --> 00:03:07,090
And then we have on Saturday, I don't have the schedule.

40
00:03:08,090 --> 00:03:11,090
Let me make sure I get this right.

41
00:03:16,150 --> 00:03:18,990
And Saturday, there we have it.

42
00:03:19,870 --> 00:03:23,770
We have on Saturday, the badge clinic.

43
00:03:29,710 --> 00:03:32,810
And this is one full hour.

44
00:03:32,810 --> 00:03:37,210
During the badge clinic, we're going to get into some advanced use.

45
00:03:37,330 --> 00:03:39,270
We're going to do things like

46
00:03:46,290 --> 00:03:48,830
impersonation of other devices.

47
00:03:48,830 --> 00:03:52,090
We will do examination

48
00:03:55,830 --> 00:03:58,930
of other NDEF formats.

49
00:04:00,850 --> 00:04:02,190
So do you get the point?

50
00:04:02,190 --> 00:04:07,550
We're going to do some more advanced stuff here, but this is like office hours too.

51
00:04:07,550 --> 00:04:10,510
So you can ask easy questions if you like.

52
00:04:13,330 --> 00:04:15,990
I hope you can read my writing.

53
00:04:16,230 --> 00:04:17,390
Can you read my writing?

54
00:04:17,390 --> 00:04:20,670
Can everybody raise your hand that can read?

55
00:04:20,670 --> 00:04:22,090
Oh, you can't?

56
00:04:22,090 --> 00:04:23,230
No, you can't?

57
00:04:23,230 --> 00:04:27,490
Okay, then I'll just have to write a bit better.

58
00:04:27,630 --> 00:04:30,010
Okay, on Sunday, let me just check.

59
00:04:30,010 --> 00:04:32,070
We've got more things happening then.

60
00:04:35,130 --> 00:04:38,610
And Sunday, we have another badge clinic.

61
00:04:38,610 --> 00:04:40,490
So let's make a plan for that.

62
00:04:45,230 --> 00:04:51,190
And then this will be a free mic style.

63
00:04:51,290 --> 00:04:53,410
We can do anything we want on Sunday.

64
00:04:53,410 --> 00:04:55,230
Does that sound okay with you?

65
00:04:55,230 --> 00:04:56,470
Hands, please.

66
00:04:57,170 --> 00:05:07,210
So we're going to do on Friday today, a construction, a making of, and then we'll have a getting started, kind of a novice approach.

67
00:05:07,210 --> 00:05:09,930
Tomorrow, Saturday is going to be a badge clinic.

68
00:05:10,050 --> 00:05:11,550
Sunday will be a badge clinic.

69
00:05:11,550 --> 00:05:18,910
And tomorrow is where we get kind of more advanced with interesting things, backup and things like that.

70
00:05:19,130 --> 00:05:21,570
All right, so this kind of fell off to the side.

71
00:05:21,570 --> 00:05:23,450
Let's take a look at that.

72
00:05:23,910 --> 00:05:26,950
So this is the badge.

73
00:05:27,630 --> 00:05:29,290
Let's do this.

74
00:05:32,650 --> 00:05:35,670
It's basically a passive device.

75
00:05:35,670 --> 00:05:40,790
You can tell that there are no, there are no connectors on here.

76
00:05:42,230 --> 00:05:44,430
There are no batteries.

77
00:05:47,040 --> 00:05:49,320
There are no lights.

78
00:05:49,320 --> 00:06:14,060
Obviously, if there are no batteries and no connectors to put energy into this, right, like voltage, like current and amps, then you're not going to have much possibility to run, for example, actuators, things that act on the environment, like little fans that move air or lights that illuminate and emit photons,

79
00:06:14,060 --> 00:06:15,780
turn energy into photons.

80
00:06:15,900 --> 00:06:20,940
So it doesn't have any cable connectors, any batteries.

81
00:06:20,940 --> 00:06:23,300
There's no batteries inside.

82
00:06:23,600 --> 00:06:27,920
If you want to know how thick this is, let me just put a pen up to here.

83
00:06:28,060 --> 00:06:32,640
So this is kind of, you can see approximately the thickness.

84
00:06:32,660 --> 00:06:38,160
There would be possibly space for a very small battery, but it doesn't have one, trust me.

85
00:06:38,300 --> 00:06:39,860
We're going to take it apart soon.

86
00:06:39,860 --> 00:06:40,780
This is Friday.

87
00:06:40,780 --> 00:06:44,580
So we're going to talk about the construction and we'll take one completely apart.

88
00:06:44,580 --> 00:06:46,820
We will destruct one.

89
00:06:46,820 --> 00:06:48,200
No, how do you call that?

90
00:06:49,260 --> 00:06:53,060
We will disassemble, that's the word.

91
00:06:53,260 --> 00:06:56,240
We will disassemble one and then reassemble it again.

92
00:06:57,220 --> 00:06:57,740
Okay.

93
00:06:57,740 --> 00:07:00,300
So I don't know if the design is so artistic.

94
00:07:00,340 --> 00:07:04,260
The pyramid is symbolizes with all the various bricks.

95
00:07:04,260 --> 00:07:09,160
So the bricks are different topics or different things.

96
00:07:09,160 --> 00:07:12,600
At first, they were different NDEF pieces of information.

97
00:07:12,820 --> 00:07:14,780
And then there were different villages.

98
00:07:16,220 --> 00:07:23,600
Because after all, this is shared, the work to produce this intervillage badge is shared among a variety of villages.

99
00:07:23,780 --> 00:07:30,840
It's kind of, we're kind of in the middle of it, the Monero village, but we have a biohacking village, a red team village, IOT village.

100
00:07:31,420 --> 00:07:39,700
There is, and I don't want to miss anybody, but I'm saving the best for last because there is the rogues village as well.

101
00:07:39,700 --> 00:07:43,620
And I'm particularly happy that they've produced a game for this.

102
00:07:43,820 --> 00:07:49,120
Maybe we'll get to that, I think, tomorrow because I haven't figured out the game yet on my own.

103
00:07:49,120 --> 00:07:52,600
It really would be better if rogues village presented that.

104
00:07:53,060 --> 00:07:55,320
But let me just write those down.

105
00:07:58,860 --> 00:08:05,720
And so we, because after all, this slide system really is fantastically elegant.

106
00:08:05,720 --> 00:08:07,500
So let me just write that down.

107
00:08:07,500 --> 00:08:12,800
So these are the intervillages.

108
00:08:12,900 --> 00:08:38,560
We have Monero, we have biohacking, we have IOT, we have red team, and we have the rogues village.

109
00:08:41,200 --> 00:08:42,360
Okay.

110
00:08:42,640 --> 00:08:43,580
All right.

111
00:08:43,580 --> 00:08:47,840
So that's kind of what this crazy little pyramid symbolizes.

112
00:08:47,840 --> 00:08:50,060
I'm sure everyone in the world could do better.

113
00:08:50,060 --> 00:08:51,940
I'm really no artist there.

114
00:08:52,160 --> 00:09:06,280
And the rogues village folks from the rogues chose these very nice symbols, which are kind of a magical, yeah, magical enrichment to what we're doing here.

115
00:09:06,280 --> 00:09:08,580
Because before they were just numbers.

116
00:09:08,580 --> 00:09:12,560
I'm not sure if I have an old badge somewhere.

117
00:09:13,000 --> 00:09:14,100
You do have to be careful.

118
00:09:14,100 --> 00:09:18,780
There are a few photographs of old badges floating around.

119
00:09:18,780 --> 00:09:22,640
You look at one, you realize you like it because it has the numbers one, two, three.

120
00:09:22,640 --> 00:09:24,100
Well, be careful with that.

121
00:09:24,360 --> 00:09:26,840
The new ones, they don't have numbers.

122
00:09:26,840 --> 00:09:28,080
They have these symbols.

123
00:09:28,620 --> 00:09:28,900
All right.

124
00:09:28,900 --> 00:09:30,800
This is important for the game as well.

125
00:09:30,800 --> 00:09:38,300
These symbols have meaning during the rogues game adventure, which we'll get to that a bit later.

126
00:09:38,840 --> 00:09:39,460
Okay.

127
00:09:39,460 --> 00:09:45,120
So let's move to... where's all my paper?

128
00:09:46,660 --> 00:09:54,590
Let's move to components.

129
00:09:54,590 --> 00:09:56,410
Oops, that's a G.

130
00:09:56,410 --> 00:09:58,910
Let's do components.

131
00:10:02,990 --> 00:10:04,770
Let's do that next.

132
00:10:04,770 --> 00:10:06,290
This is a bit unorganized.

133
00:10:06,290 --> 00:10:08,090
We could talk about software.

134
00:10:08,090 --> 00:10:14,570
We could talk about a lot of things, but I'm going to talk about

135
00:10:17,670 --> 00:10:22,990
the hardware components first, not the parts.

136
00:10:22,990 --> 00:10:24,730
You'll see that in a minute.

137
00:10:25,070 --> 00:10:30,250
This is more or less the most important piece.

138
00:10:30,250 --> 00:10:32,710
Let's see if I can go downward.

139
00:10:39,520 --> 00:10:41,340
That zooms in a bit.

140
00:10:42,400 --> 00:10:46,100
So what we saw before was this thing here.

141
00:10:48,710 --> 00:10:49,930
And this is indeed...

142
00:10:52,050 --> 00:10:54,310
and this is indeed the interior.

143
00:10:54,310 --> 00:10:55,550
This is the PCB.

144
00:10:55,710 --> 00:11:00,390
So for all those who think, okay, this thing doesn't look like an electronic device.

145
00:11:00,390 --> 00:11:02,310
This is like a piece of plastic.

146
00:11:02,310 --> 00:11:04,250
Looks like a hockey puck.

147
00:11:04,290 --> 00:11:09,910
I think, yeah, the Monero hardware team probably just cut it into a triangle.

148
00:11:09,910 --> 00:11:11,290
It's a piece of plastic.

149
00:11:11,350 --> 00:11:12,890
So that's not true.

150
00:11:12,890 --> 00:11:15,210
It does have electronic circuits.

151
00:11:15,410 --> 00:11:18,510
You can even see the chips if I just get the lighting right.

152
00:11:18,770 --> 00:11:24,190
There are some integrated circuits, some switches, some traces, copper.

153
00:11:24,190 --> 00:11:35,270
If I turn it over, you really see that there's an electronic device because then we have a trace antenna for the radio transceiver inside.

154
00:11:35,270 --> 00:11:38,690
And then there's some hacking things that you can do with that as well.

155
00:11:39,150 --> 00:11:41,510
So that's the PCB.

156
00:11:42,430 --> 00:11:42,950
Okay.

157
00:11:42,950 --> 00:11:44,730
This is how it looks in the end.

158
00:11:44,730 --> 00:11:48,750
This is the finished piece.

159
00:11:52,750 --> 00:11:54,730
And this is the PCB.

160
00:11:58,000 --> 00:12:01,480
And what else is there?

161
00:12:07,400 --> 00:12:11,300
So we can go back even one more step.

162
00:12:11,300 --> 00:12:15,140
We can, let's see if I can remove this carefully.

163
00:12:16,460 --> 00:12:18,200
We can.

164
00:12:22,110 --> 00:12:27,650
We can see what the PCB looks like before it's assembled.

165
00:12:28,490 --> 00:12:29,610
All right.

166
00:12:29,610 --> 00:12:42,490
So I'm not sure if this works so well, but so this is, oh, I know what I'm doing wrong.

167
00:12:42,490 --> 00:12:43,750
That's what I need to do.

168
00:12:43,890 --> 00:12:45,030
There we go.

169
00:12:45,370 --> 00:12:47,110
So this is the panel.

170
00:12:47,110 --> 00:12:54,350
You can see that there are four PCBs in here, but they don't have any parts on them.

171
00:12:54,350 --> 00:12:56,650
If they did, they would look like this.

172
00:12:57,250 --> 00:12:58,530
See the difference?

173
00:13:00,150 --> 00:13:10,390
The parts are so small, in fact, it's a bit difficult to see them, but there are some parts here, one, two, three, and then there's one, two, three switches.

174
00:13:10,510 --> 00:13:13,270
These are kind of very slim devices.

175
00:13:13,390 --> 00:13:15,090
And this is the PCB as it starts.

176
00:13:15,090 --> 00:13:18,670
So let's go back to there.

177
00:13:19,770 --> 00:13:20,870
So that's what we're doing.

178
00:13:20,870 --> 00:13:22,610
We're starting with a PCB.

179
00:13:23,390 --> 00:13:25,250
We're starting with a PCB.

180
00:13:25,870 --> 00:13:32,610
We put the parts on the PCB, and then we end up with the assembled PCB.

181
00:13:32,610 --> 00:13:41,610
And from there, we're going to do a few other things like make it look like this.

182
00:13:45,040 --> 00:13:48,120
See how that's missing the plastic side?

183
00:13:48,240 --> 00:13:56,700
This is really just a PCB sandwiched in a front overlay and a back piece of leather.

184
00:13:57,860 --> 00:14:00,600
You can see one of them is orange and one is black.

185
00:14:01,220 --> 00:14:05,580
So now you're probably guessing there may be other colors as well, which is true.

186
00:14:06,520 --> 00:14:11,760
So from the ground up, we have the raw PCB, the assembled PCB.

187
00:14:11,760 --> 00:14:17,000
We place the membrane overlay is the proper name for it.

188
00:14:20,140 --> 00:14:23,080
And membrane overlays look like this.

189
00:14:23,080 --> 00:14:24,560
They come in a big sheet.

190
00:14:28,330 --> 00:14:30,790
And you can see that they are very thin.

191
00:14:31,410 --> 00:14:33,630
It's basically an adhesive.

192
00:14:33,630 --> 00:14:42,090
So I peel this off and place it on there.

193
00:14:42,090 --> 00:14:43,830
And that's what you get after that.

194
00:14:43,950 --> 00:14:46,450
The back is this piece of leather.

195
00:14:46,450 --> 00:14:48,810
You can see that I've cut these out with a laser.

196
00:14:49,970 --> 00:14:59,070
So the reason that we're putting leather on the back is because these badges often rub against other things.

197
00:14:59,070 --> 00:15:03,790
You place this back to back on, for example, a phone.

198
00:15:04,550 --> 00:15:09,650
So this is the classic use case.

199
00:15:09,650 --> 00:15:25,990
You take a badge, you put it on the phone, and then when it smacks on the phone there, it's going to scratch your lens unless it has, for more narrow village badges, right?

200
00:15:25,990 --> 00:15:30,250
Because we're using leather, we're using exotic stuff like front overlays.

201
00:15:30,890 --> 00:15:32,310
And so every year is a bit different.

202
00:15:32,310 --> 00:15:35,410
This year we have some unique materials, right?

203
00:15:35,410 --> 00:15:41,350
The only thing that's missing is the plastic piece.

204
00:15:41,350 --> 00:15:42,770
This is the frame.

205
00:15:43,090 --> 00:15:47,830
This is made from liquid plastic, which is ultraviolet hardened.

206
00:15:47,830 --> 00:15:49,170
So it's hard enough.

207
00:15:49,170 --> 00:15:50,290
It's somewhat brittle.

208
00:15:50,290 --> 00:15:52,590
If I really pull hard, I can break it.

209
00:15:52,590 --> 00:16:05,830
But you get the idea after you have sandwiched the PCB with a front overlay and the rear leather, and this is what you put on here to get to complete the device.

210
00:16:07,250 --> 00:16:21,090
It's not really so important to show how this is done properly because the do-it-yourself models do not come with a plastic frame because it would be very difficult to put on.

211
00:16:21,090 --> 00:16:23,190
It's actually, they usually break.

212
00:16:24,490 --> 00:16:25,710
But I got it.

213
00:16:25,710 --> 00:16:27,270
Okay, I think I got it.

214
00:16:27,810 --> 00:16:28,810
Yeah, you see that?

215
00:16:28,810 --> 00:16:30,070
You see, so this one broke.

216
00:16:30,070 --> 00:16:35,430
So that's the reason we're not sending these frames out in an unassembled manner.

217
00:16:35,430 --> 00:16:38,110
I mean, that's an excellent... I don't know.

218
00:16:38,110 --> 00:16:43,630
I don't know if that's good or bad, but this really proves the point.

219
00:16:43,830 --> 00:16:50,470
We have a need for helping people learn and sending do-it-yourself models, which cost us less time.

220
00:16:50,470 --> 00:16:52,230
And so they're less expensive.

221
00:16:52,390 --> 00:17:00,270
And the reason we didn't do it with a plastic frame is because they're brittle enough that it's very difficult to put them on.

222
00:17:00,290 --> 00:17:06,790
And so when we do this in the factory, we're breaking one, we take another one, that one doesn't break.

223
00:17:06,790 --> 00:17:10,470
We get our orange one or red one, the green one breaks.

224
00:17:10,830 --> 00:17:16,330
And so we're kind of allowed to get sloppy or to make these mistakes in the factory.

225
00:17:16,330 --> 00:17:27,670
But if we send one frame out, which with each of these sets, and the poor person, wherever they get it, maybe they're on a ship in the middle of the Atlantic, can't receive post for another three months.

226
00:17:27,670 --> 00:17:31,470
They break their frame, then they don't have, you know, it's just not nice.

227
00:17:31,470 --> 00:17:37,870
So we are sending do-it-yourself models without these plastic frames.

228
00:17:37,870 --> 00:17:43,430
And part of the do-it-yourself system, the approach, it's called you make your own frame.

229
00:17:43,430 --> 00:17:46,870
So you can probably order one.

230
00:17:46,870 --> 00:17:50,790
I mean, the open source archive shows how to construct the frame.

231
00:17:51,310 --> 00:18:04,650
But we prefer that you go, you walk down the street or across the city where you live, go to a hackerspace, a maker lab, where they have machines that can produce plastic parts.

232
00:18:04,810 --> 00:18:16,250
And you take the model, you download it off of the internet, where we've stored all of the design, and you produce your own plastic frame.

233
00:18:16,250 --> 00:18:18,110
I mean, it's not that difficult.

234
00:18:18,110 --> 00:18:21,090
It just, you have to be determined and motivated.

235
00:18:21,090 --> 00:18:29,890
And that's how you get a plastic frame if you don't want to receive one purchased in a kit with a badge like this.

236
00:18:30,490 --> 00:18:31,030
Right?

237
00:18:31,030 --> 00:18:40,570
So I kind of went all the way from the start of the unassembled board to the assembled device now.

238
00:18:41,590 --> 00:18:51,550
The intermediate steps like peeling off the adhesive paper and peeling of the leather, it's not that easy, but you get the picture.

239
00:18:51,550 --> 00:19:00,610
If you do receive a do-it-yourself or DIY badge, it's going to be quite obvious where the parts go, right?

240
00:19:00,610 --> 00:19:08,950
There is a user manual, but I'm hoping people aren't too confused about that.

241
00:19:09,890 --> 00:19:13,330
So this is where we're at now.

242
00:19:15,430 --> 00:19:19,050
What we can do next is take a look at...

243
00:19:22,130 --> 00:19:24,990
Oh, I kind of missed a couple things.

244
00:19:25,070 --> 00:19:27,710
So we're going to backtrack just a bit, shall we?

245
00:19:28,270 --> 00:19:32,630
So this is kind of what the pieces of plastic look like.

246
00:19:32,630 --> 00:19:34,510
This one, I got it wrong.

247
00:19:34,510 --> 00:19:36,630
So it's broken up here.

248
00:19:36,630 --> 00:19:37,870
It stopped working correctly.

249
00:19:37,870 --> 00:19:39,390
This is the green.

250
00:19:39,450 --> 00:19:41,750
And you can kind of see that it's translucent.

251
00:19:42,050 --> 00:19:52,330
So if you do a DIY attempt and you make your own plastic enclosure frame, you have a wide variety of choices.

252
00:19:52,330 --> 00:19:54,050
You can do clear plastic.

253
00:19:54,050 --> 00:19:57,470
This is why the ultraviolet cured method is so nice.

254
00:19:59,310 --> 00:20:01,810
Anyway, so I thought that might be worth demonstrating.

255
00:20:01,810 --> 00:20:07,210
This is approximately 20 frames, but the job stopped too early.

256
00:20:07,210 --> 00:20:09,670
So you can see that it's a bit messed up.

257
00:20:10,350 --> 00:20:15,350
And that's where the ICs come out of, tapes like this, right?

258
00:20:15,350 --> 00:20:18,190
So this is for those of you who are maybe a bit curious.

259
00:20:18,450 --> 00:20:21,730
I can't even get close enough, probably, to show you these parts.

260
00:20:21,730 --> 00:20:22,990
They are so small.

261
00:20:25,110 --> 00:20:27,670
And these are integrated circuits.

262
00:20:28,550 --> 00:20:37,110
So in an advanced badge clinic, I won't promise anything, but I do have a microscope.

263
00:20:37,450 --> 00:20:42,850
And I'm going to try to get a bit more wild and crazy with the OBS open source.

264
00:20:42,910 --> 00:20:43,670
What is it?

265
00:20:43,670 --> 00:20:45,550
Open Broadcasting System.

266
00:20:45,830 --> 00:20:47,890
I'm a big dummy with video.

267
00:20:47,890 --> 00:20:53,490
So if I get it right, then we can look at these integrated circuits under a microscope .

268
00:20:53,490 --> 00:20:57,510
But this is actually what is placed in these positions.

269
00:20:57,510 --> 00:20:59,610
One, two, three.

270
00:21:00,770 --> 00:21:01,450
Okay .

271
00:21:01,450 --> 00:21:03,270
So that's the construction.

272
00:21:04,530 --> 00:21:06,570
And here are the switches.

273
00:21:07,230 --> 00:21:11,750
If you can see that there are some switches on there.

274
00:21:11,970 --> 00:21:14,010
These are dome switches.

275
00:21:14,150 --> 00:21:15,610
This is not very typical.

276
00:21:15,610 --> 00:21:18,530
These dome switches are nearly never used.

277
00:21:18,530 --> 00:21:21,090
And you need a front overlay if you're going to...

278
00:21:21,690 --> 00:21:23,590
see how that's embossed there?

279
00:21:24,010 --> 00:21:30,270
And it makes a clicking sound when you click on there.

280
00:21:30,270 --> 00:21:31,710
That's because it's tactile.

281
00:21:31,710 --> 00:21:33,310
So it's a tactile switch.

282
00:21:33,570 --> 00:21:35,250
And it's embossed.

283
00:21:35,250 --> 00:21:36,990
And that's what the switches look like.

284
00:21:36,990 --> 00:21:38,650
They're called dome switches.

285
00:21:40,070 --> 00:21:40,750
Right.

286
00:21:41,390 --> 00:21:42,450
So... okay.

287
00:21:42,450 --> 00:21:44,350
I'm never going to get those out of it.

288
00:21:47,950 --> 00:21:51,170
Keep this place clean is what they always say at the lab.

289
00:21:51,690 --> 00:21:54,790
Here's a sample of the liquid plastic.

290
00:21:54,990 --> 00:21:58,150
So I'm not even going to open this up because it stinks quite bad.

291
00:21:58,410 --> 00:22:00,310
And it's photosensitive.

292
00:22:00,650 --> 00:22:02,610
It's the photo emulsion.

293
00:22:03,270 --> 00:22:05,890
So that's kind of how these badges are made.

294
00:22:06,370 --> 00:22:09,750
There's the frame.

295
00:22:09,750 --> 00:22:10,190
Okay.

296
00:22:10,190 --> 00:22:20,530
So once in a while, I'm just going to take a look on Discord because if you have questions in between...

297
00:22:22,750 --> 00:22:26,510
I'm not sure if I can do this Discord and OBS at the same time.

298
00:22:26,510 --> 00:22:27,510
Does that work?

299
00:22:27,650 --> 00:22:29,050
Justin, does that work?

300
00:22:29,450 --> 00:22:30,630
Answer me.

301
00:22:33,600 --> 00:22:34,000
Yeah.

302
00:22:34,000 --> 00:22:34,280
Okay.

303
00:22:34,280 --> 00:22:35,000
So let's see.

304
00:22:35,000 --> 00:22:36,940
I'm starting Discord now.

305
00:22:36,940 --> 00:22:48,240
And I will try to respond to questions because as we go, some of these things are extra interesting or extra confusing or you made one just like that, but you have this question.

306
00:22:48,240 --> 00:22:52,180
So I'm going to try to maybe field a few questions as we go.

307
00:22:52,300 --> 00:23:01,320
When we leave it towards the end and we're talking a whole hour, then you may forget the question.

308
00:23:01,480 --> 00:23:03,180
That would not be good.

309
00:23:04,060 --> 00:23:05,360
Here, check this one out.

310
00:23:05,360 --> 00:23:06,720
This is another frame.

311
00:23:06,720 --> 00:23:11,720
This is a kind of a... it's not white, but it's not clear either.

312
00:23:11,780 --> 00:23:12,820
What do you call that?

313
00:23:12,820 --> 00:23:15,160
Milk color or ice?

314
00:23:15,260 --> 00:23:16,920
I have no idea.

315
00:23:19,240 --> 00:23:20,760
Anyway, so that's kind of nice.

316
00:23:20,760 --> 00:23:35,200
And the advantage for all of you who maybe are experienced with fused deposition modeling style 3D printing, that's where you have hard plastic and you melt it into a new shape.

317
00:23:36,220 --> 00:23:45,580
The big advantage, in my opinion, to this liquid photo emulsion is that you can actually mix them.

318
00:23:45,580 --> 00:23:54,460
You take a bottle like this and you mix it with a blue and you mix the blue with a red, you end up with purple.

319
00:23:54,460 --> 00:23:55,080
Right?

320
00:23:55,080 --> 00:23:56,660
So that's pretty nice.

321
00:23:56,660 --> 00:24:03,380
And then you pour in some transparent, and so it makes the purple that was solid, it's translucent now.

322
00:24:03,420 --> 00:24:06,720
So yeah, those are some tips if you're going to make your own frame.

323
00:24:08,160 --> 00:24:11,500
You can do that and you can maybe... it depends on the printers.

324
00:24:11,500 --> 00:24:19,780
The SLA, the stereolithographic printers are a lot more expensive than the FDM, the fused deposition modeling printers.

325
00:24:19,900 --> 00:24:21,340
You can use either one.

326
00:24:21,340 --> 00:24:27,240
You may have to adjust the model just a bit if you use FDM because the technique is a bit different.

327
00:24:27,240 --> 00:24:29,940
So the overhangs, well, it's not important.

328
00:24:29,940 --> 00:24:34,300
We'll maybe get to that if there is a question and I'll make a drawing here on the paper.

329
00:24:35,660 --> 00:24:36,940
All right.

330
00:24:36,940 --> 00:24:39,580
So what we were going to do

331
00:24:43,090 --> 00:24:51,260
was move to the package contents.

332
00:24:51,260 --> 00:24:52,240
Shall we?

333
00:24:52,500 --> 00:24:53,580
Shall we do that?

334
00:24:53,580 --> 00:24:55,220
Can I find a package?

335
00:24:57,200 --> 00:24:58,340
Probably not.

336
00:24:58,340 --> 00:25:00,080
Yes, I found one.

337
00:25:01,260 --> 00:25:02,800
All right.

338
00:25:06,600 --> 00:25:08,940
So there's a package.

339
00:25:10,160 --> 00:25:15,820
They're going to always be black like this, so don't send back black packages.

340
00:25:15,820 --> 00:25:17,120
It's not the Mafia.

341
00:25:17,120 --> 00:25:19,140
It's Monero Devices.

342
00:25:19,240 --> 00:25:23,800
Sends you a black package in the mail just for extra hackiness.

343
00:25:23,800 --> 00:25:24,320
All right.

344
00:25:24,320 --> 00:25:25,940
So that's the only thing that's in there.

345
00:25:26,940 --> 00:25:32,220
So you get a pretty spiffy box this time.

346
00:25:32,220 --> 00:25:38,480
We had some problems last year with the... do you remember those?

347
00:25:38,600 --> 00:25:41,000
We had some problems with those.

348
00:25:41,540 --> 00:25:48,860
On the side there, these connectors were getting bent because we didn't have proper packaging.

349
00:25:48,860 --> 00:25:51,120
How can I focus on that?

350
00:25:52,160 --> 00:25:54,360
I don't want my fingerprint in there.

351
00:25:54,680 --> 00:25:56,200
No, it's not focusing, guys.

352
00:25:56,200 --> 00:25:57,140
But you get the idea.

353
00:25:57,140 --> 00:26:03,240
There is a metal piece on the side, and those were getting bent.

354
00:26:03,240 --> 00:26:06,500
I think some of us had to bend them back in shape.

355
00:26:06,500 --> 00:26:12,000
So we didn't have very good boxes last year, and we learned our lesson.

356
00:26:12,000 --> 00:26:13,140
That's kind of what this is about.

357
00:26:13,140 --> 00:26:19,760
We're always doing experiments, trying new things, and then about half of them work, and the other half, well, they don't.

358
00:26:20,320 --> 00:26:20,820
All right.

359
00:26:20,820 --> 00:26:22,020
So this is the box.

360
00:26:22,020 --> 00:26:36,440
It has a label on the side so we know what it is, because there is black, there's orange, red for the red team, blue, blue team, you know, green for Matrix Green and biohacking, and orange for Monero.

361
00:26:37,580 --> 00:26:40,600
So that's the back of the box.

362
00:26:40,600 --> 00:26:49,140
We have a great UPC code from our friends at Hack5, who is one of the premier shops as well as Cypher Market that are carrying this.

363
00:26:49,540 --> 00:26:55,780
We decided to test and experiment a bit with holographic seals on the side.

364
00:26:55,780 --> 00:26:57,260
I'm not sure who's doing this.

365
00:26:57,260 --> 00:27:01,940
I think there are a few other manufacturers of secure hardware that do this.

366
00:27:02,080 --> 00:27:11,740
I don't think... I mean, I'm going to keep... we're going to keep putting holograms on there, but not for security.

367
00:27:11,780 --> 00:27:12,660
Okay.

368
00:27:12,880 --> 00:27:14,320
I mean, think about it.

369
00:27:14,320 --> 00:27:20,580
If you have a hairdryer, you probably can get these holograms off quite easily.

370
00:27:20,580 --> 00:27:21,400
What do you do then?

371
00:27:21,400 --> 00:27:25,840
You open the package, you manipulate the thing, right?

372
00:27:25,840 --> 00:27:32,040
You program new identifiers on there or some other sloppy thing, anything you like, real dirty stuff.

373
00:27:32,160 --> 00:27:34,660
Then you put the device back in the package.

374
00:27:35,520 --> 00:27:38,940
You're very careful with the seals that you removed.

375
00:27:38,960 --> 00:27:40,860
I mean, I haven't tested this too much.

376
00:27:40,860 --> 00:27:45,820
I was hoping that the intrusion detection team, there's an actual village.

377
00:27:45,860 --> 00:27:47,520
I'm sorry, not team, it's a village.

378
00:27:47,520 --> 00:27:53,980
I was hoping that intrusion detection would be on board with the intervillage, that they would be one of the, whatever, five or 10 villages.

379
00:27:53,980 --> 00:28:00,300
But the intrusion detection village is not active or participating this year.

380
00:28:00,300 --> 00:28:01,940
This is like a few others.

381
00:28:02,100 --> 00:28:05,960
Sky team, Skytox, I'm sorry, Skytox is not participating.

382
00:28:06,180 --> 00:28:08,160
There are a few villages like that.

383
00:28:08,160 --> 00:28:11,300
So we got unlucky with that.

384
00:28:11,300 --> 00:28:17,260
And we just have to wait until we get a report from them, if this is good for any reason at all.

385
00:28:18,000 --> 00:28:27,520
The one thing that is very, very good about this, if we can get a focus, is that it is quite attractive.

386
00:28:28,500 --> 00:28:36,660
Do any of you see the symbol, which is inside the holographic 3D?

387
00:28:37,980 --> 00:28:39,740
You probably do.

388
00:28:39,740 --> 00:28:44,420
You're just all raising your hands and I can't see you.

389
00:28:44,800 --> 00:28:45,480
All right.

390
00:28:45,480 --> 00:28:49,860
So that's kind of a very, very, very cool appearance, right?

391
00:28:49,860 --> 00:28:52,720
That's one of the reasons we will keep using these.

392
00:28:54,960 --> 00:29:00,420
And maybe if we get lucky, we kind of learn how to use them, how to apply them in a manner.

393
00:29:00,420 --> 00:29:12,380
The truth is, if you remove this, it will leave a, what do they call it, self-destructive message behind.

394
00:29:12,380 --> 00:29:13,640
It says void.

395
00:29:14,120 --> 00:29:15,960
You can't choose too many.

396
00:29:15,960 --> 00:29:17,020
Void is one of them.

397
00:29:17,020 --> 00:29:25,280
So if you peel that off, I won't demonstrate now, but if you peel it off, it is pretty easy to see that there was a seal there and now there's not anymore.

398
00:29:25,280 --> 00:29:32,080
And if you put a new seal on, then it covers up the void marking.

399
00:29:32,200 --> 00:29:35,400
But if you look at it closely, there's something wrong with it.

400
00:29:35,400 --> 00:29:36,200
You can tell.

401
00:29:36,200 --> 00:29:48,360
So that's kind of, if we get far enough into examining this intrusion detection holographic seal system, we may get lucky enough to make it useful for us.

402
00:29:48,360 --> 00:30:04,900
It probably will at least solve the very low hanging fruit problem where a person would just go into the box, replace the badge with one that they have in their pocket because theirs is broken and yours is not.

403
00:30:04,900 --> 00:30:09,920
So this is kind of a low hanging fruit intrusion protection slash detection.

404
00:30:09,920 --> 00:30:16,980
We've got the shrink wrap to make it, you know, set up, put another five minutes of time for an attacker.

405
00:30:16,980 --> 00:30:23,480
We've got the holographic seals and the only, there's not a good reason for this.

406
00:30:23,480 --> 00:30:31,920
I mean, we do pre-program these three EEPROMs with data out of the factory and they're random data.

407
00:30:31,920 --> 00:30:42,060
So we don't store them, which means it's impossible to track or obtain, you know, any organization, institute, agency.

408
00:30:42,060 --> 00:30:52,760
It would be impossible to capture the database of all of these factory programmed identifiers because we don't store them, right?

409
00:30:52,760 --> 00:30:53,800
It makes no sense.

410
00:30:53,800 --> 00:30:56,520
We're just writing random data to each one.

411
00:30:56,520 --> 00:31:17,140
But if there were a meaning, if we had some reason to ensure that they're unique or something like that, to use them for signing documents, you know, like a public address or something like that, then these holographic seals may help a bit.

412
00:31:17,140 --> 00:31:30,600
They would at least protect and defend against the low hanging fruit attacks where without the shrink wrap, without the holographic seal, it would just be another 15 minutes faster to make that replacement and intrusion.

413
00:31:30,900 --> 00:31:31,500
All right.

414
00:31:31,500 --> 00:31:46,340
So that's just what I wanted to show is kind of a generic thing that we can reuse maybe for the next couple of months or a it's really laborious, time consuming and boring to design, make, and communicate with gift box manufacturers.

415
00:31:46,340 --> 00:31:48,760
So I don't want to ever do that again.

416
00:31:48,780 --> 00:31:54,920
And so we're going to have quite a few runs at this generic packaging, and this will be the first one.

417
00:31:55,480 --> 00:31:56,400
All right.

418
00:31:56,640 --> 00:31:59,400
So let's open one of these boxes up.

419
00:31:59,540 --> 00:32:03,520
That's how it is when we have the shrink wrap off.

420
00:32:03,580 --> 00:32:06,680
I'm always using this to open it up.

421
00:32:06,800 --> 00:32:10,600
It's a poor man's wrench, I guess.

422
00:32:11,140 --> 00:32:12,780
Come on, open.

423
00:32:13,080 --> 00:32:13,520
All right.

424
00:32:13,520 --> 00:32:17,340
So there we have a do -it-yourself model.

425
00:32:17,340 --> 00:32:41,200
I can tell because the do-it-yourself model has the black and white, cheap printed on a laser printer manual, whereas the more elegant model, that's the one that comes with the colorful frame, that comes with a color manual.

426
00:32:41,540 --> 00:32:49,060
And so the reason I want to show this is because I personally think this manual is the nicest part of the entire package.

427
00:32:49,060 --> 00:32:49,300
All right.

428
00:32:49,300 --> 00:32:58,300
If you're excited about holographic seals and photo emulsion, stereolithography and all that stuff, no, you got it wrong.

429
00:32:58,300 --> 00:33:02,840
This is definitely the nicest manual I've ever seen in my life.

430
00:33:03,440 --> 00:33:05,220
So the printers got it right.

431
00:33:05,220 --> 00:33:07,440
They put it on just the right gloss.

432
00:33:07,440 --> 00:33:09,500
They got the colors very good.

433
00:33:10,700 --> 00:33:22,320
But the main reason this thing looks beautiful is that we got lucky and a very talented illustrator and graphic designer contributed the design.

434
00:33:22,480 --> 00:33:25,440
I don't know if I'm allowed to say who it is.

435
00:33:25,440 --> 00:33:26,820
Can anybody guess?

436
00:33:30,340 --> 00:33:31,620
Revar, what do you think?

437
00:33:31,620 --> 00:33:32,520
Who is this?

438
00:33:33,340 --> 00:33:34,000
Really?

439
00:33:35,700 --> 00:33:37,860
No, that's not... yeah, that's him.

440
00:33:37,880 --> 00:33:38,500
All right, Revar.

441
00:33:38,540 --> 00:33:40,100
Revar got it right.

442
00:33:41,460 --> 00:33:42,200
Okay.

443
00:33:42,440 --> 00:33:45,180
So anyway, so this is the manual.

444
00:33:45,360 --> 00:33:47,000
We've got a quick start there.

445
00:33:47,000 --> 00:33:48,280
It's rather clear.

446
00:33:48,280 --> 00:33:49,720
It has a couple models.

447
00:33:49,720 --> 00:33:51,280
Their hands are on there.

448
00:33:53,020 --> 00:33:54,500
Lots of big writing.

449
00:33:54,500 --> 00:33:56,060
There's a bill of materials.

450
00:33:57,260 --> 00:34:01,720
There are a few people that participated and then it's double-sided.

451
00:34:03,120 --> 00:34:04,740
Yeah, I really like this.

452
00:34:05,800 --> 00:34:07,360
There is some code there.

453
00:34:07,360 --> 00:34:08,960
There's just enough.

454
00:34:08,960 --> 00:34:12,140
You know, this is not like a 60, a 50, 60 page manual.

455
00:34:12,140 --> 00:34:16,060
It's not stapled in the middle to make it read like a book.

456
00:34:18,620 --> 00:34:20,040
But you get the idea.

457
00:34:20,040 --> 00:34:21,960
I mean, this manual is just very, very nice.

458
00:34:22,860 --> 00:34:23,920
I don't know why.

459
00:34:25,220 --> 00:34:44,260
I mean, I'm just saying that my opinion is that it's very nice and that I wish that the illustrator and graphic designer would talk to us about it and to come on and explain his methods, his techniques, everything she or he does is open source.

460
00:34:44,260 --> 00:34:46,940
And so, I mean, the person is just wonderful.

461
00:34:47,380 --> 00:34:56,040
Anyway, so there's reasons which are not so interesting why we have a color manual and a black and white one.

462
00:34:56,040 --> 00:35:02,400
We had to do a second one because we got the idea to do a do-it-yourself model a bit late.

463
00:35:02,400 --> 00:35:06,800
And then we didn't want to have the frame on here, which was confusing.

464
00:35:06,800 --> 00:35:08,920
The do-it-yourself model doesn't come with a frame.

465
00:35:10,900 --> 00:35:13,500
That's what it comes with, but we'll get to that in a bit.

466
00:35:14,120 --> 00:35:18,160
And so, we needed kind of a different, basically a different manual.

467
00:35:18,160 --> 00:35:27,180
So, this tells you how to put it together, which really only makes sense if you have a parts kit, like a do-it-yourself parts kit.

468
00:35:27,960 --> 00:35:28,180
Right?

469
00:35:28,180 --> 00:35:34,660
So, this is kind of similar, but it's just not as beautiful, not the printing, you know, glossy paper, not as large.

470
00:35:36,080 --> 00:35:41,100
But you do get a manual either way, which I think is kind of important anyway.

471
00:35:41,100 --> 00:35:48,580
So, that's how we got to the inside of this do-it-yourself kit, right?

472
00:35:48,580 --> 00:36:02,160
So, this is the do-it-yourself, the less expensive one, the one that I actually recommend to all the hardware hackers, because let me tell you, after you remove all of this foam and stuff, what you end up with is the raw PCB like this.

473
00:36:02,160 --> 00:36:05,580
I mean, it does have assembled switches and ICs.

474
00:36:06,500 --> 00:36:25,560
But what I'm saying is that instead of an already placed piece of leather here, which blocks the circuits, what you end up with, if you receive a do-it-yourself model, is the surfaces which you can solder on.

475
00:36:25,560 --> 00:36:34,720
You can inspect them, you can attach probes, you can put a multimeter, an oscilloscope on there, and you don't have to rip the leather off.

476
00:36:35,280 --> 00:36:49,640
It's a bit unfortunate, let me say, not really disingenuous, but unfortunate that when you put the leather on, that's this stuff over here.

477
00:36:49,640 --> 00:36:56,660
When you put the leather on the back, the adhesive is so strong that it's kind of difficult to get it off.

478
00:36:57,440 --> 00:37:02,680
So then you have the problem, if you want a lanyard on there, are you going to drill through the leather?

479
00:37:02,680 --> 00:37:08,480
There's all this stuff that is easier to do before you assemble it.

480
00:37:08,480 --> 00:37:27,280
So that's the reason that you may like a do-it-yourself model instead of the fully assembled, fully luxurious, the most elegant one with the made-for-you color translucent SLA photo emulsion frame, all that stuff, right?

481
00:37:27,280 --> 00:37:28,280
And the color manual.

482
00:37:28,280 --> 00:37:31,020
I mean, I don't know, I'm just trying to give people a choice.

483
00:37:31,020 --> 00:37:32,260
I think choices are good.

484
00:37:32,260 --> 00:37:35,940
So you can do what you want.

485
00:37:35,940 --> 00:37:40,500
Anyway, this is what comes in the do-it-yourself model.

486
00:37:41,500 --> 00:37:52,070
You take this out and then you receive three components.

487
00:37:52,550 --> 00:37:58,370
It's quite obvious that the assembled PCB is there.

488
00:37:58,370 --> 00:38:15,570
We didn't want to send these out unassembled to the do-it-yourselfers because, and it's not going to, I don't think it will focus, but because the integrated circuits are so small that it's really difficult.

489
00:38:15,570 --> 00:38:17,550
Let me just show you in comparison.

490
00:38:18,110 --> 00:38:22,750
I do have somewhere, here they are.

491
00:38:26,280 --> 00:38:30,040
So I do have somewhere some standard size parts.

492
00:38:31,640 --> 00:38:38,960
And so we can, for a quick comparison, we can show, great, I lost it.

493
00:38:38,960 --> 00:38:40,300
All right, here it is.

494
00:38:40,300 --> 00:38:47,180
So we can show the size of a normal part, the SMT surface mounted technology part.

495
00:38:49,460 --> 00:38:57,380
And if you look beneath them, that's where the ICs are for the intervillage batch.

496
00:38:57,380 --> 00:38:58,720
That's how big they are.

497
00:38:58,720 --> 00:39:14,300
And what that tells you is that if these PCBs, printed circuit boards, really did arrive in your mailbox as a do-it-yourself parts kit, and you had to solder these integrated circuits onto the board, you just might go crazy.

498
00:39:14,300 --> 00:39:19,140
I mean, you definitely would abandon the project, give up, and you would not have a working badge.

499
00:39:19,140 --> 00:39:31,220
That's why we have shipped even the do-it-yourself models in a partially assembled state.

500
00:39:31,220 --> 00:39:34,240
These switches are a bit difficult to get on there as well.

501
00:39:34,240 --> 00:39:45,560
And the manual pages, which would be required to explain how to do this and get it centered just right, and how to understand that the circuit is not shorted or anything, would be another 10 pages.

502
00:39:45,560 --> 00:39:51,140
It just makes everything sloppy, difficult, unappealing, and yeah, we don't need that.

503
00:39:53,420 --> 00:40:04,520
Right, so now you know what components you receive in the bag when you receive a kit of parts.

504
00:40:04,520 --> 00:40:05,880
That's these here.

505
00:40:05,880 --> 00:40:12,320
This is the deconstruction or the before you build and construct your DIY model.

506
00:40:12,740 --> 00:40:21,320
And I think it's clear enough already, because we've talked about it, that the membrane overlay or the front cover, this goes on here, right?

507
00:40:21,320 --> 00:40:24,040
You have to peel off the back.

508
00:40:24,040 --> 00:40:25,880
It's kind of like a sticker.

509
00:40:25,880 --> 00:40:32,200
So you peel that off, put that on there, it's going to be all crooked, right?

510
00:40:32,200 --> 00:40:34,900
I mean, I may give some tips later on.

511
00:40:34,900 --> 00:40:37,640
It's, you know, if you get it crooked, you can readjust it.

512
00:40:37,640 --> 00:40:39,220
It's quite easy to do that.

513
00:40:40,220 --> 00:40:42,260
So, and then you turn it over.

514
00:40:42,980 --> 00:40:44,720
And that's the leather.

515
00:40:44,720 --> 00:40:50,660
You take the peel off of the leather, the adhesive peel, and then put it on there.

516
00:40:51,700 --> 00:40:57,420
And after you do that, you end up with almost the same thing.

517
00:40:58,760 --> 00:41:00,880
God, this place is a mess.

518
00:41:02,000 --> 00:41:08,340
Would one of the village people please come over here and clean this up?

519
00:41:08,900 --> 00:41:20,260
Because it's really difficult to give a presentation at the same time as... So I do need an assistant to come over to this table and clean up my just load of crap here.

520
00:41:20,380 --> 00:41:20,840
All right.

521
00:41:20,840 --> 00:41:24,700
So that was a joke in case you don't know, there's nobody else in this room, right?

522
00:41:24,700 --> 00:41:27,120
I keep saying, please raise your hands.

523
00:41:27,460 --> 00:41:28,580
All right.

524
00:41:28,860 --> 00:41:30,120
Nice jokes.

525
00:41:30,400 --> 00:41:30,760
Okay.

526
00:41:30,760 --> 00:41:36,580
So this is the pre-assembled, no, not pre-assembled, what do you call that?

527
00:41:36,580 --> 00:41:42,600
The unassembled, the not yet pre-assembled kit of parts for the do-it-yourself.

528
00:41:42,600 --> 00:41:48,780
And after you put the front overlay on and the back leather, then it ends up like this.

529
00:41:48,780 --> 00:41:51,040
You cannot choose a color for the DIY.

530
00:41:51,040 --> 00:42:05,500
We're just considering, okay, people can choose five colors for the pre-assembled, five for the do-it-yourself, then they can choose what, if they get a frame as well, you know, no, we don't want more than like a half dozen choices.

531
00:42:05,680 --> 00:42:09,360
This starts to get too difficult to service, right?

532
00:42:09,360 --> 00:42:13,540
So once you, if you do choose a DIY, it seems that they were quite popular.

533
00:42:13,540 --> 00:42:19,060
Most people want these because I don't know why, but it's more fun to put it together yourself, right?

534
00:42:19,240 --> 00:42:28,740
There's a few disadvantages like, well, whatever, but you get that, then it turns into this after you're finished building it yourself.

535
00:42:28,880 --> 00:42:33,660
You'll have to print your own 3D frame at the hackerspace.

536
00:42:33,660 --> 00:42:36,560
And then you put that on and that completes your device.

537
00:42:36,740 --> 00:42:37,080
All right.

538
00:42:37,080 --> 00:42:44,800
If you like the idea of receiving a color manual, I mean, anybody can do that as a beauty of open source.

539
00:42:44,800 --> 00:42:50,980
You can even have a color manual for free because you can download it, right?

540
00:42:50,980 --> 00:43:05,220
It's just a matter of if you print it, it's not going to be this size pre-folded by folding machines, perfectly 90 degree angles with no bleed to the edge printing and glossy ink, right?

541
00:43:05,220 --> 00:43:08,020
It's just, but you don't need that anyway.

542
00:43:08,020 --> 00:43:09,000
What do you need?

543
00:43:09,000 --> 00:43:14,180
You need a file download, which you can find on our shop.

544
00:43:14,180 --> 00:43:22,720
That's where you purchase, you receive a device, but you can download the free of charge user manuals as well.

545
00:43:22,720 --> 00:43:28,520
The black and white one, the color one, you get all that stuff.

546
00:43:28,520 --> 00:43:31,560
I mean, there's not a whole bunch of files to download there.

547
00:43:31,560 --> 00:43:46,900
What it's really meant for, the shop.monero devices.com, it's really meant for distribution, for helping us replace this physical model where people without masks are walking next to each other and saying, hi, I want a badge.

548
00:43:46,900 --> 00:43:50,900
And then we say, okay, there you go.

549
00:43:50,900 --> 00:43:52,520
Put it in your hands, right?

550
00:43:52,520 --> 00:44:02,120
We have to replace that pre-pandemic model with a virtual, what distributed nobody in the same room model.

551
00:44:02,120 --> 00:44:08,440
And that's why we created the shop, the factory shop called shop.monerodevices.com.

552
00:44:08,680 --> 00:44:20,360
That's where you can download manuals, but it's not made, it is made to replace the personal meeting in a room, pick up your hardware device system.

553
00:44:20,360 --> 00:44:31,740
What it's not made for is to replace the public repository where all of the design files, the archives and other things are found.

554
00:44:31,740 --> 00:44:37,680
Like for example, the source code for the manual is there.

555
00:44:37,680 --> 00:44:45,680
The PDF itself, the finished proof and copy is on the shop, as you might expect.

556
00:44:45,740 --> 00:44:48,940
And the source code for this is in the repository.

557
00:44:50,200 --> 00:45:00,120
Yeah, I'm not very well equipped, organized to start opening screen scraped and websites.

558
00:45:00,120 --> 00:45:02,820
Let's do that tomorrow, shall we?

559
00:45:03,020 --> 00:45:08,140
But, and we'll continue on just inspecting the components right now.

560
00:45:08,140 --> 00:45:11,680
But there is the S, it's called SCM.

561
00:45:11,680 --> 00:45:13,400
I'll write that down.

562
00:45:20,260 --> 00:45:23,040
So a couple URLs to remember.

563
00:45:23,040 --> 00:45:25,700
We've already covered the shop.

564
00:45:31,860 --> 00:45:33,920
That's for distribution.

565
00:45:33,920 --> 00:45:38,560
Like we always do in the village physically, we are now doing online.

566
00:45:39,300 --> 00:45:40,680
There.

567
00:45:40,680 --> 00:45:43,660
And then we have SCM.

568
00:45:45,340 --> 00:45:48,220
Then we have the SCM, which stands for

569
00:45:53,560 --> 00:45:58,580
source code management.

570
00:46:01,960 --> 00:46:04,260
Do you like the way I did that sideways?

571
00:46:05,300 --> 00:46:11,000
Does that help you if you're side to side, can't deal with it?

572
00:46:11,420 --> 00:46:13,240
All right, so you get the idea.

573
00:46:13,240 --> 00:46:15,580
This is Monero devices.

574
00:46:17,380 --> 00:46:27,920
All right, and the SCM, the source code management system, that's where you get the raw sources.

575
00:46:27,920 --> 00:46:29,040
What else should I call it?

576
00:46:29,040 --> 00:46:39,340
So you, I don't think you can receive the PDF version of the manual there, but you can receive the SVGs there, the scaled vector graphics, right?

577
00:46:39,340 --> 00:46:47,880
And then it's a bit difficult to construct a PDF from the scaled vector graphics because of fonts and things like that and lines.

578
00:46:48,440 --> 00:46:50,880
But if you want the PDF, you get it there.

579
00:46:51,440 --> 00:46:54,820
All right, so where are we and how much time do we have?

580
00:46:54,820 --> 00:47:00,120
I'm going to just take a look, see if we're doing okay.

581
00:47:00,120 --> 00:47:09,160
Now, what I'm doing right now is I'm going to our Discord DefCon channel.

582
00:47:09,160 --> 00:47:11,020
It's the village.

583
00:47:11,200 --> 00:47:22,260
Just like we have SCM and shop.monerodevices.com, we have this year no room at Valley's and no room at Paris or anywhere else, Flamingo.

584
00:47:22,260 --> 00:47:29,160
Instead, we have a chat room, a series of chat rooms on the Discord server.

585
00:47:29,160 --> 00:47:49,760
So if you're just watching this online in video, you're not sure how to get involved in DefCon in general or walk in our village if you want to do that, then the way to do it is with the Discord server.

586
00:47:50,780 --> 00:47:57,320
All right, so just let me get to our room so I can try to see.

587
00:47:57,840 --> 00:47:59,840
God, there's a lot of channels.

588
00:48:01,560 --> 00:48:06,600
So there's a lot of content, even though it's virtual this year.

589
00:48:07,040 --> 00:48:18,840
And probably the next thing we will do is take questions and answers because we've covered all of the components that go into building a badge.

590
00:48:19,580 --> 00:48:26,320
And that's what we wanted to focus on in this hour.

591
00:48:26,680 --> 00:48:29,200
I'm just scrolling, scrolling, scrolling.

592
00:48:29,200 --> 00:48:33,020
There's the crypto village, the ethics village, and we're coming up soon.

593
00:48:33,140 --> 00:48:35,260
Ham and radio village.

594
00:48:35,920 --> 00:48:37,100
What's wrong with these people?

595
00:48:37,100 --> 00:48:39,060
Why aren't they part of the inner village?

596
00:48:39,940 --> 00:48:42,160
Oh, here is a hardware hacking.

597
00:48:42,460 --> 00:48:43,500
ICS.

598
00:48:43,500 --> 00:48:44,660
My goodness.

599
00:48:44,660 --> 00:48:47,220
IOT lock bypass.

600
00:48:47,220 --> 00:48:48,820
Lock picking.

601
00:48:48,880 --> 00:48:49,640
Here we are.

602
00:48:49,640 --> 00:48:51,500
Okay, Monero village.

603
00:48:51,680 --> 00:48:52,640
All right.

604
00:48:52,640 --> 00:48:55,800
So I don't see any questions yet.

605
00:48:55,800 --> 00:48:58,780
I'm sure that you're thoroughly bored.

606
00:48:59,020 --> 00:49:09,500
But I also don't have much more to say about the components that make up these badges.

607
00:49:09,500 --> 00:49:16,300
So it's time to either close early or ask for questions.

608
00:49:17,020 --> 00:49:20,220
And if anybody would please...

609
00:49:22,000 --> 00:49:22,760
Right.

610
00:49:22,760 --> 00:49:27,140
If you have a question... I actually don't know how this works.

611
00:49:27,140 --> 00:49:32,120
I assume that a moderator will... How does this work?

612
00:49:32,160 --> 00:49:39,720
If you're not on Discord and you're on IRC or something, somebody translate, put it on Discord.

613
00:49:39,720 --> 00:49:44,320
Otherwise, we're going to finish a few minutes early.

614
00:49:45,180 --> 00:49:48,740
So let me see what we're doing here.

615
00:49:52,040 --> 00:49:57,360
Yeah, the general channel is no questions.

616
00:49:57,360 --> 00:49:59,720
Off topic channel.

617
00:50:00,460 --> 00:50:01,980
No questions.

618
00:50:01,980 --> 00:50:07,080
And the office channel for office hours, I see no questions at all.

619
00:50:07,900 --> 00:50:13,640
Okay, so we're going to finish early.

620
00:50:13,640 --> 00:50:16,500
It's the last chance to ask your question.

621
00:50:17,060 --> 00:50:19,880
And nothing there.

622
00:50:19,880 --> 00:50:30,780
So please come back for the next presentation, which I can just find it.

623
00:50:36,290 --> 00:50:40,390
By the way, you cannot download these slides.

624
00:50:40,390 --> 00:50:41,070
Okay?

625
00:50:41,070 --> 00:50:42,850
You can't download them.

626
00:50:42,930 --> 00:50:44,950
Sorry about that.

627
00:50:45,670 --> 00:50:47,290
Because they're paper.

628
00:50:47,290 --> 00:50:48,790
Do you get it?

629
00:50:48,950 --> 00:50:49,290
All right.

630
00:50:49,290 --> 00:50:50,490
These slides are paper.

631
00:50:50,490 --> 00:50:51,870
Don't download them.

632
00:50:51,870 --> 00:50:52,130
All right.

633
00:50:52,130 --> 00:50:59,230
So the next presentation is by some jerk.

634
00:50:59,790 --> 00:51:00,390
Oh, no.

635
00:51:00,390 --> 00:51:01,030
Wait a minute.

636
00:51:01,030 --> 00:51:01,910
No, that's me.

637
00:51:01,910 --> 00:51:03,490
I'm giving the next presentation.

638
00:51:03,490 --> 00:51:07,130
It's called getting started with the intervillage badge.

639
00:51:07,270 --> 00:51:12,190
So what we will do there is learn how to actually use one, how to do something.

640
00:51:14,230 --> 00:51:17,430
Yeah, it's something useful with them.

641
00:51:17,430 --> 00:51:18,170
Okay.

642
00:51:18,990 --> 00:51:24,570
And that's going to be the other three, two days after today.
