[00:03.720 --> 00:05.280]  Okay, guys.
[00:07.000 --> 00:14.140]  But we will start the next presentation, which is called This Year's Village Badge.
[00:14.320 --> 00:20.960]  My name is Michael Schloff von Benevitz, and I believe that our AV is working very well.
[00:20.960 --> 00:29.000]  Thanks so much to SGP and to AGS. And let me just get started with this.
[00:29.000 --> 00:33.660]  We have some interesting devices to take a look at.
[00:36.700 --> 00:39.100]  To begin with, we have...
[00:41.640 --> 00:47.500]  To begin with, I should turn off my stream so there's no echo. Okay, that's better.
[00:48.680 --> 00:52.780]  So this is the high-tech slide deck that you may have heard of
[00:52.780 --> 00:56.980]  with the paper and the pencil. That's how we're doing it this year.
[00:56.980 --> 01:00.020]  This year's Village Badge.
[01:08.640 --> 01:16.040]  And what we have here, we've got basically three days. We've got Friday. We've got Saturday.
[01:18.140 --> 01:23.360]  Let me do this. We've got Friday, we've got Saturday, and we've got Sunday.
[01:23.900 --> 01:32.300]  So this is where we are. And I'm just explaining this because there's a little bit of organization.
[01:32.300 --> 01:40.000]  Some people are interested in beginner style, novice topics. Others are into the more advanced stuff.
[01:40.000 --> 01:50.900]  So we've got this presentation now. Later, we've got another one. It's called Getting Started.
[01:55.030 --> 02:00.970]  Okay, and in this one, we're going to talk about the construction,
[02:06.390 --> 02:08.290]  how it's made.
[02:10.570 --> 02:16.290]  A lot of people have been asking about, can they make it on their own? Is it open source? Are there
[02:16.290 --> 02:23.010]  design archives? This type of thing. So that's what we're going to do now on Friday in this first
[02:23.010 --> 02:29.310]  hour. Okay, so we're going to talk about the SCM, the source code management, the open source,
[02:29.310 --> 02:37.070]  all of the things that you can store on disk, like the design archives. And after this hour
[02:37.070 --> 02:43.510]  is over, we'll take a short break and we'll have another presentation with me as well. Just like
[02:43.510 --> 02:49.230]  Rira said before, this is the Michael evening. And we will talk about getting started with the badge.
[02:49.230 --> 02:55.230]  So this second hour, this will be things like, what is the first thing that I can do once I have
[02:55.230 --> 03:02.050]  it in my hands? This is the way it looks. So let me just put that on the side. And then we have on
[03:02.050 --> 03:18.050]  Saturday, I don't have the schedule. Let me make sure I get this right. And Saturday, there we have
[03:18.050 --> 03:34.270]  it. We have on Saturday, the badge clinic. And this is one full hour. During the badge clinic,
[03:34.270 --> 03:39.270]  we're going to get into some advanced use. We're going to do things like
[03:46.290 --> 03:52.090]  impersonation of other devices. We will do examination
[03:55.830 --> 03:58.930]  of other NDEF formats.
[04:00.850 --> 04:04.770]  So do you get the point? We're going to do some more advanced stuff here,
[04:04.770 --> 04:10.510]  but this is like office hours too. So you can ask easy questions if you like.
[04:13.330 --> 04:19.210]  I hope you can read my writing. Can you read my writing? Can everybody raise your hand
[04:19.210 --> 04:25.810]  that can read? Oh, you can't? No, you can't? Okay, then I'll just have to write a bit
[04:26.450 --> 04:32.070]  better. Okay, on Sunday, let me just check. We've got more things happening then.
[04:35.130 --> 04:40.490]  And Sunday, we have another badge clinic. So let's make a plan for that.
[04:45.230 --> 04:54.090]  And then this will be a free mic style. We can do anything we want on Sunday. Does that sound
[04:54.090 --> 05:03.770]  okay with you? Hands, please. So we're going to do on Friday today, a construction, a making of,
[05:03.770 --> 05:08.410]  and then we'll have a getting started, kind of a novice approach. Tomorrow, Saturday is going to
[05:08.410 --> 05:13.750]  be a badge clinic. Sunday will be a badge clinic. And tomorrow is where we get kind of more advanced
[05:13.750 --> 05:21.190]  with interesting things, backup and things like that. All right, so this kind of fell off to the
[05:21.190 --> 05:34.930]  side. Let's take a look at that. So this is the badge. Let's do this. It's basically a passive
[05:34.930 --> 05:44.430]  device. You can tell that there are no, there are no connectors on here. There are no batteries.
[05:47.040 --> 05:54.160]  There are no lights. Obviously, if there are no batteries and no connectors to put energy into
[05:54.160 --> 06:02.440]  this, right, like voltage, like current and amps, then you're not going to have much possibility
[06:02.440 --> 06:10.760]  to run, for example, actuators, things that act on the environment, like little fans that move air
[06:10.760 --> 06:17.640]  or lights that illuminate and emit photons, turn energy into photons. So it doesn't have any
[06:18.200 --> 06:24.760]  cable connectors, any batteries. There's no batteries inside. If you want to know how
[06:24.760 --> 06:30.760]  thick this is, let me just put a pen up to here. So this is kind of, you can see approximately
[06:31.480 --> 06:37.360]  the thickness. There would be possibly space for a very small battery, but it doesn't have one,
[06:37.360 --> 06:41.700]  trust me. We're going to take it apart soon. This is Friday. So we're going to talk about
[06:41.700 --> 06:47.460]  the construction and we'll take one completely apart. We will destruct one. No, how do you call
[06:47.460 --> 06:56.240]  that? We will disassemble, that's the word. We will disassemble one and then reassemble it again.
[06:57.220 --> 07:03.040]  Okay. So I don't know if the design is so artistic. The pyramid is symbolizes with all
[07:03.040 --> 07:09.540]  the various bricks. So the bricks are different topics or different things. At first,
[07:09.540 --> 07:14.780]  they were different NDEF pieces of information. And then there were different villages.
[07:16.220 --> 07:22.120]  Because after all, this is shared, the work to produce this intervillage badge is shared among
[07:22.280 --> 07:26.840]  a variety of villages. It's kind of, we're kind of in the middle of it, the Monero village,
[07:26.840 --> 07:33.420]  but we have a biohacking village, a red team village, IOT village. There is, and I don't want
[07:33.420 --> 07:39.940]  to miss anybody, but I'm saving the best for last because there is the rogues village as well. And
[07:39.940 --> 07:45.860]  I'm particularly happy that they've produced a game for this. Maybe we'll get to that, I think,
[07:45.860 --> 07:50.500]  tomorrow because I haven't figured out the game yet on my own. It really would be better if rogues
[07:50.500 --> 08:01.860]  village presented that. But let me just write those down. And so we, because after all, this
[08:01.860 --> 08:09.880]  slide system really is fantastically elegant. So let me just write that down. So these are the
[08:09.880 --> 08:23.160]  intervillages. We have Monero, we have biohacking,
[08:24.200 --> 08:38.560]  we have IOT, we have red team, and we have the rogues village.
[08:41.200 --> 08:48.980]  Okay. All right. So that's kind of what this crazy little pyramid symbolizes. I'm sure everyone in the
[08:48.980 --> 08:55.260]  world could do better. I'm really no artist there. And the rogues village folks from the rogues chose
[08:55.260 --> 09:05.680]  these very nice symbols, which are kind of a magical, yeah, magical enrichment to what we're
[09:05.680 --> 09:12.560]  doing here. Because before they were just numbers. I'm not sure if I have an old badge somewhere.
[09:13.000 --> 09:18.780]  You do have to be careful. There are a few photographs of old badges floating around.
[09:18.780 --> 09:23.220]  You look at one, you realize you like it because it has the numbers one, two, three. Well, be careful
[09:23.220 --> 09:29.260]  with that. The new ones, they don't have numbers. They have these symbols. All right. This is
[09:29.260 --> 09:34.920]  important for the game as well. These symbols have meaning during the rogues game adventure,
[09:34.920 --> 09:45.120]  which we'll get to that a bit later. Okay. So let's move to... where's all my paper?
[09:46.660 --> 09:58.910]  Let's move to components. Oops, that's a G. Let's do components.
[10:02.990 --> 10:09.150]  Let's do that next. This is a bit unorganized. We could talk about software. We could talk about a
[10:09.150 --> 10:23.270]  lot of things, but I'm going to talk about the hardware components first, not the parts.
[10:23.270 --> 10:30.250]  You'll see that in a minute. This is more or less the most important piece.
[10:30.250 --> 10:32.710]  Let's see if I can go downward.
[10:39.520 --> 10:49.930]  That zooms in a bit. So what we saw before was this thing here. And this is indeed...
[10:52.050 --> 10:57.570]  and this is indeed the interior. This is the PCB. So for all those who think, okay,
[10:57.570 --> 11:02.310]  this thing doesn't look like an electronic device. This is like a piece of plastic.
[11:02.310 --> 11:08.990]  Looks like a hockey puck. I think, yeah, the Monero hardware team probably just cut it into
[11:09.170 --> 11:15.210]  a triangle. It's a piece of plastic. So that's not true. It does have electronic circuits.
[11:15.410 --> 11:20.530]  You can even see the chips if I just get the lighting right. There are some integrated circuits,
[11:20.530 --> 11:26.750]  some switches, some traces, copper. If I turn it over, you really see that there's an electronic
[11:26.750 --> 11:35.670]  device because then we have a trace antenna for the radio transceiver inside. And then there's
[11:35.670 --> 11:43.570]  some hacking things that you can do with that as well. So that's the PCB. Okay. This is how
[11:43.570 --> 12:01.480]  it looks in the end. This is the finished piece. And this is the PCB. And what else is there?
[12:07.400 --> 12:15.140]  So we can go back even one more step. We can, let's see if I can remove this carefully.
[12:16.460 --> 12:29.950]  We can. We can see what the PCB looks like before it's assembled. All right. So
[12:32.290 --> 12:35.250]  I'm not sure if this works so well, but
[12:37.890 --> 12:46.050]  so this is, oh, I know what I'm doing wrong. That's what I need to do. There we go. So this
[12:46.050 --> 12:54.350]  is the panel. You can see that there are four PCBs in here, but they don't have any parts on them.
[12:54.350 --> 13:02.010]  If they did, they would look like this. See the difference? The parts are so small, in fact,
[13:02.010 --> 13:08.330]  it's a bit difficult to see them, but there are some parts here, one, two, three,
[13:08.330 --> 13:13.270]  and then there's one, two, three switches. These are kind of very slim devices.
[13:13.390 --> 13:18.670]  And this is the PCB as it starts. So let's go back to there.
[13:19.770 --> 13:25.250]  So that's what we're doing. We're starting with a PCB. We're starting with a PCB.
[13:25.870 --> 13:33.490]  We put the parts on the PCB, and then we end up with the assembled PCB. And from there,
[13:33.490 --> 13:47.060]  we're going to do a few other things like make it look like this. See how that's missing the plastic
[13:47.060 --> 13:56.700]  side? This is really just a PCB sandwiched in a front overlay and a back piece of leather.
[13:57.860 --> 14:02.520]  You can see one of them is orange and one is black. So now you're probably guessing there
[14:02.520 --> 14:10.100]  may be other colors as well, which is true. So from the ground up, we have the raw PCB,
[14:10.100 --> 14:17.000]  the assembled PCB. We place the membrane overlay is the proper name for it.
[14:20.140 --> 14:24.560]  And membrane overlays look like this. They come in a big sheet.
[14:28.330 --> 14:34.950]  And you can see that they are very thin. It's basically an adhesive. So I peel this off
[14:37.130 --> 14:38.650]  and place it
[14:41.070 --> 14:47.050]  on there. And that's what you get after that. The back is this piece of leather. You can see that
[14:47.050 --> 14:53.910]  I've cut these out with a laser. So the reason that we're putting leather on the back is because
[14:53.910 --> 15:03.790]  these badges often rub against other things. You place this back to back on, for example, a phone.
[15:04.550 --> 15:13.070]  So this is the classic use case. You take a badge, you put it on the phone,
[15:13.070 --> 15:23.890]  and then when it smacks on the phone there, it's going to scratch your lens unless it has,
[15:23.890 --> 15:28.690]  for more narrow village badges, right? Because we're using leather, we're using exotic stuff
[15:28.690 --> 15:33.610]  like front overlays. And so every year is a bit different. This year we have some unique
[15:34.230 --> 15:42.770]  materials, right? The only thing that's missing is the plastic piece. This is the frame.
[15:43.090 --> 15:49.170]  This is made from liquid plastic, which is ultraviolet hardened. So it's hard enough.
[15:49.170 --> 15:53.670]  It's somewhat brittle. If I really pull hard, I can break it. But you get the idea
[15:53.670 --> 16:01.070]  after you have sandwiched the PCB with a front overlay and the rear leather,
[16:01.070 --> 16:05.830]  and this is what you put on here to get to complete the device.
[16:07.250 --> 16:13.830]  It's not really so important to show how this is done properly because the do-it-yourself models
[16:13.830 --> 16:21.710]  do not come with a plastic frame because it would be very difficult to put on. It's actually,
[16:21.710 --> 16:29.090]  they usually break. But I got it. Okay, I think I got it. Yeah, you see that? You see,
[16:29.090 --> 16:34.650]  so this one broke. So that's the reason we're not sending these frames out in an unassembled
[16:34.650 --> 16:39.970]  manner. I mean, that's an excellent... I don't know. I don't know if that's good or bad, but
[16:39.970 --> 16:48.210]  this really proves the point. We have a need for helping people learn and sending do-it-yourself
[16:48.210 --> 16:53.890]  models, which cost us less time. And so they're less expensive. And the reason we didn't do it
[16:53.890 --> 17:00.270]  with a plastic frame is because they're brittle enough that it's very difficult to put them on.
[17:00.290 --> 17:05.730]  And so when we do this in the factory, we're breaking one, we take another one, that one
[17:05.730 --> 17:12.610]  doesn't break. We get our orange one or red one, the green one breaks. And so we're kind of allowed
[17:12.610 --> 17:18.790]  to get sloppy or to make these mistakes in the factory. But if we send one frame out, which with
[17:18.790 --> 17:24.470]  each of these sets, and the poor person, wherever they get it, maybe they're on a ship in the middle
[17:24.470 --> 17:29.130]  of the Atlantic, can't receive post for another three months. They break their frame, then they
[17:29.130 --> 17:35.230]  don't have, you know, it's just not nice. So we are sending do-it-yourself models
[17:35.890 --> 17:41.830]  without these plastic frames. And part of the do-it-yourself system, the approach, it's called
[17:41.830 --> 17:48.810]  you make your own frame. So you can probably order one. I mean, the open source archive shows
[17:48.810 --> 17:56.030]  how to construct the frame. But we prefer that you go, you walk down the street or across the city
[17:56.030 --> 18:02.890]  where you live, go to a hackerspace, a maker lab, where they have machines that can produce plastic
[18:03.610 --> 18:09.870]  parts. And you take the model, you download it off of the internet, where we've stored all of the
[18:09.870 --> 18:18.690]  design, and you produce your own plastic frame. I mean, it's not that difficult. It just,
[18:18.690 --> 18:22.790]  you have to be determined and motivated. And that's how you get a plastic frame
[18:22.790 --> 18:29.890]  if you don't want to receive one purchased in a kit with a badge like this.
[18:30.490 --> 18:36.950]  Right? So I kind of went all the way from the start of the unassembled board
[18:37.890 --> 18:40.570]  to the assembled device now.
[18:41.590 --> 18:48.190]  The intermediate steps like peeling off the adhesive paper and peeling of the leather,
[18:48.190 --> 18:56.450]  it's not that easy, but you get the picture. If you do receive a do-it-yourself or DIY badge,
[18:57.350 --> 19:04.330]  it's going to be quite obvious where the parts go, right? There is a user manual,
[19:04.330 --> 19:13.330]  but I'm hoping people aren't too confused about that. So this is where we're at now.
[19:15.430 --> 19:19.050]  What we can do next is take a look at...
[19:22.130 --> 19:27.710]  Oh, I kind of missed a couple things. So we're going to backtrack just a bit, shall we?
[19:28.270 --> 19:35.690]  So this is kind of what the pieces of plastic look like. This one, I got it wrong. So it's
[19:35.690 --> 19:40.310]  broken up here. It stopped working correctly. This is the green. And you can kind of see
[19:40.310 --> 19:47.790]  that it's translucent. So if you do a DIY attempt and you make your own plastic
[19:48.970 --> 19:54.370]  enclosure frame, you have a wide variety of choices. You can do clear plastic. This is
[19:54.370 --> 20:01.150]  why the ultraviolet cured method is so nice. Anyway, so I thought that might be worth
[20:01.150 --> 20:08.070]  demonstrating. This is approximately 20 frames, but the job stopped too early. So you can see
[20:08.070 --> 20:15.350]  that it's a bit messed up. And that's where the ICs come out of, tapes like this, right?
[20:15.350 --> 20:20.070]  So this is for those of you who are maybe a bit curious. I can't even get close enough,
[20:20.070 --> 20:22.990]  probably, to show you these parts. They are so small.
[20:25.110 --> 20:32.670]  And these are integrated circuits. So in an advanced badge clinic,
[20:33.430 --> 20:38.690]  I won't promise anything, but I do have a microscope. And I'm going to try to get a bit
[20:38.690 --> 20:46.610]  more wild and crazy with the OBS open source. What is it? Open Broadcasting System. I'm a big
[20:46.610 --> 20:53.010]  dummy with video. So if I get it right, then we can look at these integrated circuits under a
[20:53.010 --> 21:01.350]  microscope. But this is actually what is placed in these positions. One, two, three.
[21:01.350 --> 21:09.070]  Okay. So that's the construction. And here are the switches. If you can see
[21:09.070 --> 21:15.610]  that there are some switches on there. These are dome switches. This is not very typical.
[21:15.610 --> 21:21.090]  These dome switches are nearly never used. And you need a front overlay if you're going to...
[21:21.690 --> 21:30.690]  see how that's embossed there? And it makes a clicking sound when you click on there. That's
[21:30.690 --> 21:36.410]  because it's tactile. So it's a tactile switch. And it's embossed. And that's what the switches
[21:36.410 --> 21:43.710]  look like. They're called dome switches. Right. So... okay. I'm never going to get those out of
[21:43.710 --> 21:54.790]  it. Keep this place clean is what they always say at the lab. Here's a sample of the liquid plastic.
[21:54.990 --> 22:01.150]  So I'm not even going to open this up because it stinks quite bad. And it's photosensitive. It's
[22:01.150 --> 22:10.450]  the photo emulsion. So that's kind of how these badges are made. There's the frame. Okay. So
[22:12.270 --> 22:20.530]  once in a while, I'm just going to take a look on Discord because if you have questions in between...
[22:22.750 --> 22:27.510]  I'm not sure if I can do this Discord and OBS at the same time. Does that work?
[22:27.650 --> 22:37.720]  Justin, does that work? Answer me. Yeah. Okay. So let's see. I'm starting Discord now. And I will
[22:37.720 --> 22:43.520]  try to respond to questions because as we go, some of these things are extra interesting or
[22:43.520 --> 22:49.040]  extra confusing or you made one just like that, but you have this question. So I'm going to try
[22:49.040 --> 22:56.340]  to maybe field a few questions as we go. When we leave it towards the end and we're talking a whole
[22:56.340 --> 23:05.680]  hour, then you may forget the question. That would not be good. Here, check this one out. This is
[23:05.680 --> 23:12.300]  another frame. This is a kind of a... it's not white, but it's not clear either. What do you call
[23:12.300 --> 23:22.780]  that? Milk color or ice? I have no idea. Anyway, so that's kind of nice. And the advantage for all
[23:22.780 --> 23:30.340]  of you who maybe are experienced with fused deposition modeling style 3D printing, that's
[23:30.340 --> 23:40.600]  where you have hard plastic and you melt it into a new shape. The big advantage, in my opinion,
[23:40.600 --> 23:46.860]  to this liquid photo emulsion is that you can actually mix them. You take a bottle like this
[23:47.540 --> 23:54.460]  and you mix it with a blue and you mix the blue with a red, you end up with purple.
[23:54.460 --> 24:00.400]  Right? So that's pretty nice. And then you pour in some transparent, and so it makes the purple
[24:00.400 --> 24:05.580]  that was solid, it's translucent now. So yeah, those are some tips if you're going to make your
[24:05.580 --> 24:12.620]  own frame. You can do that and you can maybe... it depends on the printers. The SLA, the
[24:14.800 --> 24:18.540]  stereolithographic printers are a lot more expensive than the FDM, the fused deposition
[24:18.540 --> 24:23.480]  modeling printers. You can use either one. You may have to adjust the model just a bit
[24:23.990 --> 24:29.320]  if you use FDM because the technique is a bit different. So the overhangs, well, it's not
[24:29.320 --> 24:34.300]  important. We'll maybe get to that if there is a question and I'll make a drawing here on the paper.
[24:35.660 --> 24:39.580]  All right. So what we were going to do
[24:43.090 --> 24:55.220]  was move to the package contents. Shall we? Shall we do that? Can I find a package?
[24:57.200 --> 25:02.800]  Probably not. Yes, I found one. All right.
[25:06.600 --> 25:08.940]  So there's a package.
[25:10.160 --> 25:16.500]  They're going to always be black like this, so don't send back black packages. It's not the
[25:16.500 --> 25:23.800]  Mafia. It's Monero Devices. Sends you a black package in the mail just for extra hackiness.
[25:23.800 --> 25:29.240]  All right. So that's the only thing that's in there. So you get a pretty spiffy
[25:30.840 --> 25:38.480]  box this time. We had some problems last year with the... do you remember those?
[25:38.600 --> 25:46.000]  We had some problems with those. On the side there, these connectors were getting bent
[25:46.600 --> 25:51.120]  because we didn't have proper packaging. How can I focus on that?
[25:52.160 --> 26:01.080]  I don't want my fingerprint in there. No, it's not focusing, guys. But you get the idea. There is a
[26:01.080 --> 26:04.540]  metal piece on the side, and those were getting bent. I think some of us
[26:04.540 --> 26:10.980]  had to bend them back in shape. So we didn't have very good boxes last year,
[26:10.980 --> 26:15.580]  and we learned our lesson. That's kind of what this is about. We're always doing experiments,
[26:15.580 --> 26:19.760]  trying new things, and then about half of them work, and the other half, well, they don't.
[26:20.320 --> 26:24.800]  All right. So this is the box. It has a label on the side so we know what it is,
[26:24.800 --> 26:31.000]  because there is black, there's orange, red for the red team, blue, blue team, you know,
[26:31.000 --> 26:40.760]  green for Matrix Green and biohacking, and orange for Monero. So that's the back of the box. We have
[26:41.080 --> 26:47.600]  a great UPC code from our friends at Hack5, who is one of the premier shops as well as Cypher Market
[26:47.600 --> 26:54.440]  that are carrying this. We decided to test and experiment a bit with holographic seals
[26:55.040 --> 27:00.060]  on the side. I'm not sure who's doing this. I think there are a few other manufacturers of
[27:00.060 --> 27:05.440]  secure hardware that do this. I don't think... I mean, I'm going to keep... we're going to keep
[27:05.440 --> 27:15.380]  putting holograms on there, but not for security. Okay. I mean, think about it. If you have a
[27:15.380 --> 27:21.700]  hairdryer, you probably can get these holograms off quite easily. What do you do then? You open
[27:21.700 --> 27:28.960]  the package, you manipulate the thing, right? You program new identifiers on there or some
[27:28.960 --> 27:34.660]  other sloppy thing, anything you like, real dirty stuff. Then you put the device back in the package.
[27:35.520 --> 27:40.860]  You're very careful with the seals that you removed. I mean, I haven't tested this too much.
[27:40.860 --> 27:46.880]  I was hoping that the intrusion detection team, there's an actual village. I'm sorry, not team,
[27:46.880 --> 27:50.760]  it's a village. I was hoping that intrusion detection would be on board with the intervillage,
[27:50.760 --> 27:57.280]  that they would be one of the, whatever, five or 10 villages. But the intrusion detection village
[27:57.280 --> 28:04.140]  is not active or participating this year. This is like a few others. Sky team, Skytox, I'm sorry,
[28:04.140 --> 28:10.680]  Skytox is not participating. There are a few villages like that. So we got unlucky with
[28:10.680 --> 28:16.340]  that. And we just have to wait until we get a report from them, if this is good for any reason
[28:16.340 --> 28:25.600]  at all. The one thing that is very, very good about this, if we can get a focus, is that it is
[28:25.600 --> 28:36.660]  quite attractive. Do any of you see the symbol, which is inside the holographic 3D?
[28:37.980 --> 28:45.840]  You probably do. You're just all raising your hands and I can't see you. All right. So that's
[28:45.840 --> 28:51.860]  kind of a very, very, very cool appearance, right? That's one of the reasons we will keep using
[28:51.860 --> 29:00.420]  these. And maybe if we get lucky, we kind of learn how to use them, how to apply them in a manner.
[29:00.420 --> 29:10.180]  The truth is, if you remove this, it will leave a, what do they call it, self-destructive
[29:11.300 --> 29:17.080]  message behind. It says void. You can't choose too many. Void is one of them. So
[29:17.080 --> 29:22.220]  if you peel that off, I won't demonstrate now, but if you peel it off, it is pretty easy to
[29:22.220 --> 29:27.720]  see that there was a seal there and now there's not anymore. And if you put a new seal on,
[29:28.280 --> 29:35.220]  then it covers up the void marking. But if you look at it closely, there's something wrong with
[29:35.220 --> 29:42.760]  it. You can tell. So that's kind of, if we get far enough into examining this intrusion detection
[29:42.760 --> 29:50.360]  holographic seal system, we may get lucky enough to make it useful for us. It probably will at least
[29:50.360 --> 30:00.000]  solve the very low hanging fruit problem where a person would just go into the box,
[30:00.000 --> 30:04.280]  replace the badge with one that they have in their pocket because theirs is broken and yours
[30:04.280 --> 30:10.500]  is not. So this is kind of a low hanging fruit intrusion protection slash detection. We've got
[30:10.500 --> 30:16.980]  the shrink wrap to make it, you know, set up, put another five minutes of time for an attacker.
[30:16.980 --> 30:23.720]  We've got the holographic seals and the only, there's not a good reason for this. I mean,
[30:23.720 --> 30:32.080]  we do pre-program these three EEPROMs with data out of the factory and they're random data. So
[30:32.080 --> 30:40.360]  we don't store them, which means it's impossible to track or obtain, you know, any organization,
[30:40.360 --> 30:47.860]  institute, agency. It would be impossible to capture the database of all of these factory
[30:47.860 --> 30:54.100]  programmed identifiers because we don't store them, right? It makes no sense. We're just
[30:54.100 --> 30:59.940]  writing random data to each one. But if there were a meaning, if we had some reason
[31:01.280 --> 31:08.440]  to ensure that they're unique or something like that, to use them for signing documents,
[31:08.440 --> 31:16.120]  you know, like a public address or something like that, then these holographic seals may
[31:16.120 --> 31:21.080]  help a bit. They would at least protect and defend against the low hanging fruit attacks where
[31:21.080 --> 31:25.120]  without the shrink wrap, without the holographic seal, it would just be another
[31:25.640 --> 31:32.540]  15 minutes faster to make that replacement and intrusion. All right. So that's just what I wanted
[31:32.540 --> 31:38.420]  to show is kind of a generic thing that we can reuse maybe for the next couple of months or a
[31:38.420 --> 31:45.640]  it's really laborious, time consuming and boring to design, make, and communicate with gift box
[31:45.640 --> 31:50.820]  manufacturers. So I don't want to ever do that again. And so we're going to have quite a few
[31:50.820 --> 31:57.960]  runs at this generic packaging, and this will be the first one. All right. So let's open one
[31:57.960 --> 32:05.460]  of these boxes up. That's how it is when we have the shrink wrap off. I'm always using this to
[32:05.460 --> 32:15.660]  open it up. It's a poor man's wrench, I guess. Come on, open. All right. So there we have a
[32:15.660 --> 32:24.040]  do-it-yourself model. I can tell because the do-it-yourself model has the black and white,
[32:24.040 --> 32:34.180]  cheap printed on a laser printer manual, whereas the more elegant model, that's the one that comes
[32:34.180 --> 32:43.360]  with the colorful frame, that comes with a color manual. And so the reason I want to show this is
[32:43.360 --> 32:49.300]  because I personally think this manual is the nicest part of the entire package. All right.
[32:49.300 --> 32:57.000]  If you're excited about holographic seals and photo emulsion, stereolithography and all that stuff,
[32:57.000 --> 33:02.840]  no, you got it wrong. This is definitely the nicest manual I've ever seen in my life.
[33:03.440 --> 33:09.500]  So the printers got it right. They put it on just the right gloss. They got the colors very good.
[33:10.700 --> 33:16.880]  But the main reason this thing looks beautiful is that we got lucky and a very talented
[33:16.880 --> 33:24.800]  illustrator and graphic designer contributed the design. I don't know if I'm allowed to say who it
[33:24.800 --> 33:37.860]  is. Can anybody guess? Revar, what do you think? Who is this? Really? No, that's not... yeah, that's him.
[33:37.880 --> 33:45.180]  All right, Revar. Revar got it right. Okay. So anyway, so this is the manual.
[33:45.360 --> 33:51.280]  We've got a quick start there. It's rather clear. It has a couple models. Their hands are on there.
[33:53.020 --> 33:56.060]  Lots of big writing. There's a bill of materials.
[33:57.260 --> 34:01.720]  There are a few people that participated and then it's double-sided.
[34:03.120 --> 34:08.960]  Yeah, I really like this. There is some code there. There's just enough.
[34:08.960 --> 34:14.700]  You know, this is not like a 60, a 50, 60 page manual. It's not stapled in the middle to make
[34:14.700 --> 34:21.960]  it read like a book. But you get the idea. I mean, this manual is just very, very nice.
[34:22.860 --> 34:29.560]  I don't know why. I mean, I'm just saying that my opinion is that it's very nice and that I wish
[34:31.640 --> 34:39.580]  that the illustrator and graphic designer would talk to us about it and to come on and explain
[34:39.580 --> 34:45.200]  his methods, his techniques, everything she or he does is open source. And so, I mean,
[34:45.200 --> 34:52.160]  the person is just wonderful. Anyway, so there's reasons which are not so interesting why we have
[34:52.320 --> 34:59.780]  a color manual and a black and white one. We had to do a second one because we got the idea to do
[34:59.940 --> 35:05.660]  a do-it-yourself model a bit late. And then we didn't want to have the frame on here,
[35:05.660 --> 35:08.920]  which was confusing. The do-it-yourself model doesn't come with a frame.
[35:10.900 --> 35:16.040]  That's what it comes with, but we'll get to that in a bit. And so, we needed kind of a different,
[35:16.940 --> 35:20.200]  basically a different manual. So, this tells you how to put it together,
[35:20.580 --> 35:27.180]  which really only makes sense if you have a parts kit, like a do-it-yourself parts kit.
[35:27.960 --> 35:32.540]  Right? So, this is kind of similar, but it's just not as beautiful, not the printing,
[35:32.540 --> 35:37.860]  you know, glossy paper, not as large. But you do get a manual either way,
[35:38.640 --> 35:46.700]  which I think is kind of important anyway. So, that's how we got to the inside of this
[35:46.700 --> 35:51.140]  do-it-yourself kit, right? So, this is the do-it-yourself, the less expensive one,
[35:51.140 --> 35:55.760]  the one that I actually recommend to all the hardware hackers, because let me tell you,
[35:55.760 --> 36:02.440]  after you remove all of this foam and stuff, what you end up with is the raw PCB like this. I mean,
[36:02.440 --> 36:09.280]  it does have assembled switches and ICs. But what I'm saying is that instead of
[36:10.080 --> 36:15.720]  an already placed piece of leather here, which blocks the circuits,
[36:16.360 --> 36:24.400]  what you end up with, if you receive a do-it-yourself model, is the surfaces which
[36:24.400 --> 36:30.180]  you can solder on. You can inspect them, you can attach probes, you can put a multimeter,
[36:30.180 --> 36:40.020]  an oscilloscope on there, and you don't have to rip the leather off. It's a bit unfortunate,
[36:40.020 --> 36:47.240]  let me say, not really disingenuous, but unfortunate that when you put the leather on,
[36:47.240 --> 36:54.380]  that's this stuff over here. When you put the leather on the back, the adhesive is so strong
[36:54.380 --> 37:00.120]  that it's kind of difficult to get it off. So then you have the problem, if you want a lanyard
[37:00.120 --> 37:05.660]  on there, are you going to drill through the leather? There's all this stuff that is easier
[37:05.660 --> 37:13.520]  to do before you assemble it. So that's the reason that you may like a do-it-yourself model
[37:13.520 --> 37:22.440]  instead of the fully assembled, fully luxurious, the most elegant one with the made-for-you color
[37:22.440 --> 37:29.040]  translucent SLA photo emulsion frame, all that stuff, right? And the color manual. I mean,
[37:29.040 --> 37:32.800]  I don't know, I'm just trying to give people a choice. I think choices are good. So you can
[37:35.020 --> 37:42.740]  do what you want. Anyway, this is what comes in the do-it-yourself model. You take this out
[37:44.000 --> 37:54.410]  and then you receive three components. It's quite obvious that the
[37:56.210 --> 38:02.470]  assembled PCB is there. We didn't want to send these out unassembled to the do-it-yourselfers
[38:02.470 --> 38:09.290]  because, and it's not going to, I don't think it will focus, but because the integrated circuits
[38:09.290 --> 38:20.070]  are so small that it's really difficult. Let me just show you in comparison. I do have somewhere,
[38:21.370 --> 38:30.040]  here they are. So I do have somewhere some standard size parts.
[38:31.640 --> 38:40.300]  And so we can, for a quick comparison, we can show, great, I lost it. All right, here it is.
[38:40.300 --> 38:47.180]  So we can show the size of a normal part, the SMT surface mounted technology part.
[38:49.460 --> 38:57.380]  And if you look beneath them, that's where the ICs are for the intervillage batch.
[38:57.380 --> 39:02.980]  That's how big they are. And what that tells you is that if these PCBs, printed circuit boards,
[39:02.980 --> 39:08.920]  really did arrive in your mailbox as a do-it-yourself parts kit, and you had to solder
[39:09.440 --> 39:15.360]  these integrated circuits onto the board, you just might go crazy. I mean, you definitely would
[39:15.360 --> 39:19.140]  abandon the project, give up, and you would not have a working badge.
[39:19.140 --> 39:23.580]  That's why we have shipped even the do-it-yourself
[39:26.140 --> 39:33.700]  models in a partially assembled state. These switches are a bit difficult to get on there
[39:33.700 --> 39:38.200]  as well. And the manual pages, which would be required to explain how to do this
[39:38.200 --> 39:42.660]  and get it centered just right, and how to understand that the circuit is not
[39:42.660 --> 39:47.140]  shorted or anything, would be another 10 pages. It just makes everything sloppy,
[39:47.140 --> 39:51.140]  difficult, unappealing, and yeah, we don't need that.
[39:53.420 --> 40:02.460]  Right, so now you know what components you receive in the bag when you receive a
[40:03.180 --> 40:10.040]  kit of parts. That's these here. This is the deconstruction or the before you build and
[40:10.040 --> 40:16.040]  construct your DIY model. And I think it's clear enough already, because we've talked about it,
[40:16.040 --> 40:22.700]  that the membrane overlay or the front cover, this goes on here, right? You have to peel off
[40:23.200 --> 40:28.520]  the back. It's kind of like a sticker. So you peel that off, put that on there,
[40:28.520 --> 40:35.440]  it's going to be all crooked, right? I mean, I may give some tips later on. It's, you know,
[40:35.440 --> 40:41.580]  if you get it crooked, you can readjust it. It's quite easy to do that. So, and then you turn it
[40:41.580 --> 40:49.240]  over. And that's the leather. You take the peel off of the leather, the adhesive peel, and then
[40:49.240 --> 40:57.420]  put it on there. And after you do that, you end up with almost the same thing.
[40:58.760 --> 41:08.340]  God, this place is a mess. Would one of the village people please come over here and clean this up?
[41:08.900 --> 41:14.600]  Because it's really difficult to give a presentation at the same time as... So I do
[41:14.600 --> 41:21.040]  need an assistant to come over to this table and clean up my just load of crap here. All right. So
[41:21.040 --> 41:25.580]  that was a joke in case you don't know, there's nobody else in this room, right? I keep saying,
[41:25.580 --> 41:34.760]  please raise your hands. All right. Nice jokes. Okay. So this is the pre-assembled, no,
[41:34.760 --> 41:39.180]  not pre-assembled, what do you call that? The unassembled, the not yet pre-assembled
[41:40.380 --> 41:46.780]  kit of parts for the do-it-yourself. And after you put the front overlay on and the back leather,
[41:46.780 --> 41:53.640]  then it ends up like this. You cannot choose a color for the DIY. We're just considering, okay,
[41:53.640 --> 41:58.220]  people can choose five colors for the pre-assembled, five for the do-it-yourself,
[41:58.220 --> 42:03.340]  then they can choose what, if they get a frame as well, you know, no, we don't want more than
[42:03.340 --> 42:10.620]  like a half dozen choices. This starts to get too difficult to service, right? So once you,
[42:10.620 --> 42:14.560]  if you do choose a DIY, it seems that they were quite popular. Most people want these
[42:15.060 --> 42:19.680]  because I don't know why, but it's more fun to put it together yourself, right? There's a few
[42:19.680 --> 42:26.160]  disadvantages like, well, whatever, but you get that, then it turns into this after you're finished
[42:26.860 --> 42:34.160]  building it yourself. You'll have to print your own 3D frame at the hackerspace. And then you put
[42:34.160 --> 42:41.900]  that on and that completes your device. All right. If you like the idea of receiving a color manual,
[42:41.900 --> 42:46.960]  I mean, anybody can do that as a beauty of open source. You can even have a color manual
[42:48.340 --> 42:53.420]  for free because you can download it, right? It's just a matter of if you print it,
[42:53.420 --> 42:59.940]  it's not going to be this size pre-folded by folding machines, perfectly 90 degree angles
[43:00.620 --> 43:07.340]  with no bleed to the edge printing and glossy ink, right? It's just, but you don't need that
[43:07.340 --> 43:14.180]  anyway. What do you need? You need a file download, which you can find on our shop.
[43:14.180 --> 43:21.360]  That's where you purchase, you receive a device, but you can download the free of charge user
[43:21.360 --> 43:28.700]  manuals as well. The black and white one, the color one, you get all that stuff. I mean,
[43:28.700 --> 43:33.980]  there's not a whole bunch of files to download there. What it's really meant for, the shop.monero
[43:33.980 --> 43:41.400]  devices.com, it's really meant for distribution, for helping us replace this physical model where
[43:41.400 --> 43:47.400]  people without masks are walking next to each other and saying, hi, I want a badge. And then we
[43:47.400 --> 43:56.100]  say, okay, there you go. Put it in your hands, right? We have to replace that pre-pandemic model
[43:56.100 --> 44:03.640]  with a virtual, what distributed nobody in the same room model. And that's why we created the
[44:03.640 --> 44:11.280]  shop, the factory shop called shop.monerodevices.com. That's where you can download manuals,
[44:11.280 --> 44:18.480]  but it's not made, it is made to replace the personal meeting in a room, pick up your
[44:18.480 --> 44:27.440]  hardware device system. What it's not made for is to replace the public repository where all of the
[44:27.440 --> 44:35.580]  design files, the archives and other things are found. Like for example, the source code
[44:35.580 --> 44:43.820]  for the manual is there. The PDF itself, the finished proof and copy is on the shop,
[44:43.820 --> 44:48.940]  as you might expect. And the source code for this is in the repository.
[44:50.200 --> 44:56.200]  Yeah, I'm not very well equipped, organized to start opening screen scraped and
[44:58.780 --> 45:06.080]  websites. Let's do that tomorrow, shall we? But, and we'll continue on just inspecting the
[45:06.080 --> 45:13.400]  components right now. But there is the S, it's called SCM. I'll write that down.
[45:20.260 --> 45:25.700]  So a couple URLs to remember. We've already covered the shop.
[45:31.860 --> 45:38.560]  That's for distribution. Like we always do in the village physically, we are now doing online.
[45:39.300 --> 45:43.660]  There. And then we have SCM.
[45:45.340 --> 45:48.220]  Then we have the SCM, which stands for
[45:53.560 --> 46:04.260]  source code management. Do you like the way I did that sideways?
[46:05.300 --> 46:13.240]  Does that help you if you're side to side, can't deal with it? All right, so you get the idea.
[46:13.240 --> 46:24.520]  This is Monero devices. All right, and the SCM, the source code management system,
[46:24.520 --> 46:29.740]  that's where you get the raw sources. What else should I call it? So you,
[46:29.740 --> 46:35.900]  I don't think you can receive the PDF version of the manual there, but you can receive the SVGs
[46:35.900 --> 46:42.580]  there, the scaled vector graphics, right? And then it's a bit difficult to construct a PDF
[46:42.580 --> 46:47.880]  from the scaled vector graphics because of fonts and things like that and lines.
[46:48.440 --> 46:54.540]  But if you want the PDF, you get it there. All right, so where are we and how much time do we
[46:54.540 --> 47:02.340]  have? I'm going to just take a look, see if we're doing okay. Now, what I'm doing right now is
[47:02.340 --> 47:15.460]  I'm going to our Discord DefCon channel. It's the village. Just like we have SCM and shop.monerodevices.com,
[47:15.460 --> 47:22.260]  we have this year no room at Valley's and no room at Paris or anywhere else, Flamingo.
[47:22.260 --> 47:29.860]  Instead, we have a chat room, a series of chat rooms on the Discord server. So if you're just
[47:29.860 --> 47:37.540]  watching this online in video, you're not sure how to get involved in DefCon in general or
[47:37.540 --> 47:49.760]  walk in our village if you want to do that, then the way to do it is with the Discord server.
[47:50.780 --> 47:59.840]  All right, so just let me get to our room so I can try to see. God, there's a lot of channels.
[48:01.560 --> 48:09.180]  So there's a lot of content, even though it's virtual this year. And probably the next thing
[48:09.180 --> 48:15.440]  we will do is take questions and answers because we've covered all of the components
[48:16.040 --> 48:22.480]  that go into building a badge. And that's what we wanted to focus on
[48:24.540 --> 48:30.280]  in this hour. I'm just scrolling, scrolling, scrolling. There's the crypto village,
[48:30.280 --> 48:36.820]  the ethics village, and we're coming up soon. Ham and radio village. What's wrong with these
[48:36.820 --> 48:43.500]  people? Why aren't they part of the inner village? Oh, here is a hardware hacking. ICS.
[48:43.500 --> 48:51.500]  My goodness. IOT lock bypass. Lock picking. Here we are. Okay, Monero village.
[48:51.680 --> 48:59.500]  All right. So I don't see any questions yet. I'm sure that you're thoroughly bored. But
[49:01.560 --> 49:09.500]  I also don't have much more to say about the components that make up these badges.
[49:09.500 --> 49:20.220]  So it's time to either close early or ask for questions. And if anybody would please...
[49:22.000 --> 49:27.820]  Right. If you have a question... I actually don't know how this works. I assume
[49:27.820 --> 49:36.200]  that a moderator will... How does this work? If you're not on Discord and you're on IRC or
[49:36.200 --> 49:41.340]  something, somebody translate, put it on Discord. Otherwise, we're going to finish
[49:42.960 --> 49:48.740]  a few minutes early. So let me see what we're doing here.
[49:52.040 --> 49:59.720]  Yeah, the general channel is no questions. Off topic channel.
[50:00.460 --> 50:07.080]  No questions. And the office channel for office hours, I see no questions at all.
[50:07.900 --> 50:16.500]  Okay, so we're going to finish early. It's the last chance to ask your question.
[50:17.060 --> 50:30.780]  And nothing there. So please come back for the next presentation, which I can just find it.
[50:36.290 --> 50:44.950]  By the way, you cannot download these slides. Okay? You can't download them. Sorry about that.
[50:45.670 --> 50:51.870]  Because they're paper. Do you get it? All right. These slides are paper. Don't download them.
[50:51.870 --> 51:01.910]  All right. So the next presentation is by some jerk. Oh, no. Wait a minute. No, that's me.
[51:01.910 --> 51:07.130]  I'm giving the next presentation. It's called getting started with the intervillage badge.
[51:07.270 --> 51:12.190]  So what we will do there is learn how to actually use one, how to do something.
[51:14.230 --> 51:23.330]  Yeah, it's something useful with them. Okay. And that's going to be the other three, two days
[51:23.330 --> 51:24.570]  after today.
