WEBVTT 00:05.660 --> 00:09.130 Okay, I think things are okay now. 00:12.140 --> 00:21.840 Kind of okay, because I realize now that I forgot to change the title of this presentation from yesterday. 00:21.840 --> 00:27.840 Yesterday we did a presentation called Getting Started the Village Badge. 00:27.840 --> 00:31.260 And today it's called, what is it called? 00:31.260 --> 00:33.240 Today's the Badge Clinic. 00:33.680 --> 00:43.080 So this is, you know, a general purpose office hour style, ask questions and provide and share answers. 00:43.160 --> 00:44.100 Interactive. 00:44.100 --> 00:49.260 Okay, so I'm going to be checking in on the Monero. 00:49.260 --> 00:50.680 Let's see. 00:51.680 --> 00:56.600 On the Monero office text channel quite often. 00:56.600 --> 01:11.380 Okay, so it seems we have a visitor, AF3Arson there and I'll try to keep track of the general text channel as well, but maybe we should just have one channel next year. 01:11.380 --> 01:15.680 In any case, that's what the office hours channel is for now. 01:16.680 --> 01:25.080 And until any question or request comes in, I'll just go through some general purpose information. 01:25.080 --> 01:26.800 Does that work for you? 01:26.800 --> 01:28.000 Really? 01:28.820 --> 01:29.880 All right. 01:29.880 --> 01:31.220 I can't see anybody. 01:31.220 --> 01:38.040 Probably there's 3000 or maybe four people or one and a half people watching. 01:38.040 --> 01:39.500 I don't know. 01:40.640 --> 01:43.080 So we've got all of these badges here. 01:43.080 --> 01:45.060 We've got one from last year as well. 01:46.480 --> 01:56.220 Um, I don't have Yeah, I don't have from two years ago, the Becos badge, but we've got some other things to look at. 01:56.220 --> 01:57.340 We've got this. 01:57.600 --> 02:13.200 We've got this little thing here, kind of, this is, we may have some more advanced purpose, you know, for advanced people who have soldering skills and we can get into that, some impersonation, some copying of tags. 02:13.860 --> 02:16.220 And good news, folks, I have today. 02:17.520 --> 02:22.940 I have today a close circuit document. 02:23.040 --> 02:24.620 I'm sorry, a microscope. 02:24.620 --> 02:28.340 So we can take a look at some really small parts. 02:29.280 --> 02:31.100 Things like this little switch there. 02:31.100 --> 02:32.040 You see that? 02:33.680 --> 02:37.480 Right, so So we've got all of these options. 02:42.300 --> 02:45.120 So we've got all of these options is what I wanted to say. 02:45.920 --> 02:46.400 And 02:49.600 --> 02:52.880 Just checking the channels. 02:53.740 --> 02:56.360 I don't want that. 02:56.360 --> 02:58.220 No voice. 03:00.450 --> 03:01.750 This gets confusing. 03:01.750 --> 03:03.930 Okay, here's the right channel. 03:05.210 --> 03:16.210 All right, so these are the villages that are participating in the inter-village network project badge. 03:16.850 --> 03:28.830 And Monero is producing the hardware, Monero devices, in fact, that's a commercial group, a company, the biohacking village is involved, IoT as well. 03:28.890 --> 03:31.450 You have good friends there and the red team. 03:31.450 --> 03:36.970 Rogues Village produced a game. 03:37.130 --> 03:40.690 So if you look at the manual that comes with the badge. 03:40.730 --> 03:41.870 Let me just open that. 03:41.870 --> 03:44.890 It's so large that I can't even fit it on the camera. 03:44.890 --> 03:45.230 All right. 03:45.230 --> 03:46.630 Sorry about that. 03:46.650 --> 03:51.030 Here's another brought to you by just to kind of a reminder. 03:51.050 --> 03:59.690 And there's a few people not associated with villages who simply helped so much or provided and contributed things like artwork, legal advice. 04:01.990 --> 04:02.790 Materials. 04:03.070 --> 04:05.230 So that's why they're in there. 04:05.730 --> 04:07.890 It's maybe a good start to check out the manual. 04:07.890 --> 04:11.590 Each one of these blocks or pages describes something else. 04:11.610 --> 04:13.570 There's a quick start here. 04:14.210 --> 04:19.450 So whoever doesn't know what a badge looks like we can we can follow along this quick start. 04:20.630 --> 04:24.150 Yesterday I had Monero orange badges. 04:24.570 --> 04:30.490 Today I think I will change to the attack red style, if you don't mind. 04:30.490 --> 04:33.110 There's several colors. 04:34.490 --> 04:35.270 Right. 04:35.270 --> 04:42.150 So the one thing when you get started, before we get into the advanced portions. 04:42.790 --> 04:45.740 So you might have a phone like this. 04:46.480 --> 04:52.020 And you want to make sure that you're logged in. 04:52.020 --> 04:53.360 How do you even say that? 04:53.360 --> 05:05.080 If the screen is dark, if it's not active, if you can't use it actively, what's basically happening is asking, Are you a human? 05:05.080 --> 05:07.680 Do you have permissions to use this device? 05:07.920 --> 05:16.440 And if you haven't done your code or whatever you do to get in yet, then the NFC circuit will not accept any transmission. 05:16.440 --> 05:21.640 So you need to be inside the screen, you need to be able to swipe around and use your phone. 05:21.640 --> 05:29.080 Once you're inside, you need to make sure that your NFC circuit is turned on. 05:32.280 --> 05:37.400 And sometime today, maybe tomorrow, but probably today it may focus. 05:37.840 --> 05:39.180 Oh, goodness. 05:39.180 --> 05:40.360 Okay, folks. 05:41.940 --> 05:43.340 Camera is good enough. 05:43.340 --> 05:47.840 So anyway, you do maybe can tell that there's an NFC symbol there. 05:47.980 --> 05:51.620 There's an NFC symbol there and that needs to be turned on as well. 05:51.620 --> 05:58.300 So what are the situations where you cannot use your NFC powered badge is when it's turned off like this. 05:58.300 --> 06:04.540 When it's off, you're not able to use a phone, then nothing happens if I start pushing buttons and try to use the badge. 06:04.540 --> 06:06.780 Okay, you need to turn it on. 06:07.320 --> 06:08.840 Put your code in. 06:09.760 --> 06:14.060 And once you do that, at this time, you can use your badge. 06:14.060 --> 06:14.900 Let's see what happens. 06:14.900 --> 06:16.240 I'm quite curious. 06:16.720 --> 06:20.300 I'm going to push this moon button. 06:20.300 --> 06:22.640 Okay, you hear that button when you push that? 06:24.460 --> 06:26.080 So it's a tactile button. 06:26.080 --> 06:29.680 It gives you some feedback to tell you, yes, you pushed it. 06:30.340 --> 06:32.860 You idiot, you pushed the button. 06:33.220 --> 06:37.800 Okay, so I'm going to... Wow. 06:38.100 --> 06:39.520 Can you see my hands? 06:39.520 --> 06:41.880 That's from working on these badges. 06:41.880 --> 06:48.160 I got chemical injuries, chemical burns all over my hands from making the stupid badges. 06:48.220 --> 06:51.740 Alright, so that really zooms into the injuries. 06:51.740 --> 06:58.500 Anyway, I'm going to push on, I'm going to make sure it's turned on, and I'm going to push on the moon. 06:58.500 --> 07:03.400 And let's see what happens if I just do that correctly. 07:07.000 --> 07:08.280 Nothing happened. 07:08.720 --> 07:11.360 I was expecting it to go to the browser. 07:13.180 --> 07:15.600 Not sure what happens if I have the browser on. 07:18.060 --> 07:20.120 So that is surprising. 07:20.120 --> 07:21.600 Let's try another one. 07:21.900 --> 07:24.920 Maybe it doesn't have a URI programmed in. 07:25.920 --> 07:29.240 So let me push on this moon here. 07:36.810 --> 07:38.750 Yeah, okay, so I'm surprised. 07:38.750 --> 07:49.710 I thought that Android had a MIME type setup for URIs, that when it detects a URI, it opens the browser automatically. 07:50.930 --> 08:03.210 But it also could be that I have my NFC application turned on, so it's capturing all of the MIME actions. 08:03.510 --> 08:05.370 God, that's hard to push it. 08:07.450 --> 08:12.190 Oh, it also could be that I didn't program this one like a dummy. 08:12.190 --> 08:14.350 So let's try one that's programmed. 08:15.870 --> 08:18.010 That one's not programmed either. 08:24.530 --> 08:27.470 Okay, so now I'm finally... 08:29.710 --> 08:31.130 So let's just go back a bit. 08:31.130 --> 08:36.910 Now I'm finally reassured that my observation matches what I actually believe to be the case. 08:36.910 --> 08:52.510 When you have a badge, like this one, and you push a button on here, which is programmed with a URI, a Universal Resource Indicator, and that URI is a HTTP URI, right, then it will open your browser. 08:52.510 --> 09:04.230 Right, so you can see that I have this phone just to an empty page, and I'm going to push now on the moon button, which is per default out of the factory programmed with a URI. 09:06.030 --> 09:07.730 Gotta push that. 09:09.270 --> 09:14.570 Okay, opens the browser automatically to the URI that you programmed in. 09:14.570 --> 09:25.150 Okay, so the whole runaround about this is that the four suits, so that's the name of the group that is the team called Rogues Village. 09:25.150 --> 09:31.990 They created this game, and I've only gotten a few screens in, so I'm not a pro at this. 09:31.990 --> 09:35.890 I'm not in any shape to explain it. 09:35.890 --> 09:38.570 But the game works with this badge. 09:38.570 --> 09:41.290 All right, so that's the one thing. 09:41.810 --> 09:46.670 And you can see that, so we've kind of covered the quick start pretty well. 09:47.010 --> 09:51.030 You know, you have to push a button, and the thing needs to be turned on. 09:52.670 --> 09:58.130 On the last screen here, it kind of is telling you, okay, this is the URI. 09:58.130 --> 10:00.370 This is the one that's programmed into the badge. 10:01.010 --> 10:08.290 All right, so you can do all of these things using these two applications, and we hope that more people will develop applications or improve these. 10:08.290 --> 10:10.750 We can take a look at those in a minute. 10:10.750 --> 10:13.270 Let's see if there's any questions about that. 10:14.130 --> 10:15.630 Seems there isn't. 10:16.810 --> 10:19.990 Just wanted to make sure I haven't... 10:21.940 --> 10:22.680 Don't know. 10:22.680 --> 10:27.700 I guess that question, I guess there was a question, but it's crossed out, so... 10:29.280 --> 10:34.760 It's crossed out, so I must have answered it while speaking. 10:35.320 --> 10:38.520 All right, so what else can we look at in this manual? 10:38.520 --> 10:52.720 The Bill of Materials is okay if you kind of are experienced with hardware, but some of these things are understandable, like the faux leather, the leatherette, the PET plastic overlay is the thing on the front. 10:53.220 --> 10:56.600 For all of the different colors, it's the same overlay here. 10:56.600 --> 11:03.000 It's the DEF CON 28 color scheme with like a pastel green and some of these neon colors. 11:04.120 --> 11:14.320 Right, and the liquid photopolymer, that might be a bit confusing, but that's what creates these frame enclosures, right? 11:14.320 --> 11:24.250 They harden to standard rigid plastic when you shine a high intensity ultraviolet light into the liquid. 11:25.180 --> 11:29.280 Right, so that's just to answer a few questions. 11:29.340 --> 11:32.900 We can... Do you like the Gunther here? 11:33.000 --> 11:35.600 I'd like to know, Justin, do you like this Gunther? 11:35.880 --> 11:37.300 Say yes or no. 11:37.720 --> 11:39.540 I think he's wonderful. 11:39.880 --> 11:49.680 I mean this, this is a modern Gunther made specifically for us, contributed by Andres, who maybe he's watching. 11:49.680 --> 11:52.840 He's just one of the most wonderful illustrators in the world. 11:52.840 --> 12:00.880 And I mean, not just illustrators, but he created the design, the entire manual, pretty much. 12:00.880 --> 12:04.580 So I'm just astonished. 12:04.760 --> 12:16.960 Right, so we've got a big mix of a lot of different work from people like the Rogues Village, Monero Village, Monero Devices, me, Andres, a few other people that are mentioned on the front. 12:17.860 --> 12:20.760 And I just think it worked out very, very well. 12:23.140 --> 12:26.060 In any case, so that's the manual. 12:28.880 --> 12:30.200 Could you demo? 12:30.200 --> 12:31.440 Yes, that's a good idea. 12:31.440 --> 12:32.540 So we have a question. 12:32.540 --> 12:37.200 I'm going to read it out loud in case someone isn't on Discord. 12:37.380 --> 12:40.560 Could you demo the Bob Monero Devices Com app? 12:40.560 --> 12:46.220 I wasn't able to get any functionality to work, even using the links on the badge. 12:46.460 --> 12:48.740 Okay, so there's good news and bad news. 12:50.200 --> 12:52.420 Where is this headed, right? 12:52.580 --> 12:57.680 So the bad news is that the implementation is not finished yet, but we can take a look at it. 12:57.880 --> 13:07.990 Let's see, we can kind of try to understand the intention and figure out how to complete the implementation. 13:07.990 --> 13:12.990 All right, so village slides, camera, how do I go to... 13:14.610 --> 13:16.250 How do I go? 13:20.460 --> 13:22.340 I think this is it. 13:22.420 --> 13:23.420 Right. 13:24.240 --> 13:26.180 Okay, so yeah, exactly. 13:26.180 --> 13:30.400 I think, how can I, I'm not used to broadcasting. 13:31.560 --> 13:37.720 So if we have some, let me just go to some non-Monero page. 13:39.380 --> 13:41.080 Let's do Monero Village. 13:41.080 --> 13:44.520 These are the standard run of the URLs. 13:44.520 --> 13:51.780 The one that we're thinking of now that we want to reference, which is written in the manual as well. 13:51.780 --> 13:55.480 This is bob.monerodevices.com. 13:55.480 --> 13:57.940 Does anybody know what BOB stands for? 13:58.300 --> 13:59.580 I'll bet you don't. 13:59.580 --> 14:00.840 This time I'm not going to tell you. 14:00.840 --> 14:05.240 I'm just going to wait a whole hour until somebody comes up with the answer. 14:05.460 --> 14:06.280 BOB. 14:06.820 --> 14:09.880 All right, so I'm going to, I'm going to hit return there. 14:09.880 --> 14:18.540 And this is the front, the homepage for the intervillage badge, for this year's village badge. 14:19.040 --> 14:19.780 Okay. 14:20.320 --> 14:23.980 I wish we could have some camera at the same time. 14:24.100 --> 14:25.360 Messed that up a bit. 14:25.740 --> 14:32.220 So on the left, we've got all of these menu items, which we can toggle on and off. 14:32.220 --> 14:35.180 Obviously, this is just the beginning stuff, right? 14:35.180 --> 14:49.680 I know that, I know the thing that you're, you're probably wanting to see, but you can, you can kind of get informed as to the status of, okay, we can go to status as well, systems are in operation. 14:49.680 --> 14:57.340 But if we take a look at some of the more in depth things like the network, this is undergoing heavy development or go up here. 14:58.040 --> 15:08.680 And I think, okay, some of the actions, for example, expert mode, I'm hoping here that we can do some formatting of the NDEF EPROMs, things like that for experts only. 15:08.680 --> 15:21.340 So this mode, this is not yet implemented and keep checking back or develop it on your own and do a pull request and we'll get that done so that we can use these expert mode things with the badge. 15:21.340 --> 15:28.720 And then the status will probably write a better message than systems in operation will probably say, okay, expert mode is in operation now. 15:28.780 --> 15:33.220 All right, but this is very fundamental and very primitive at this time. 15:33.220 --> 15:35.440 So some of these buttons are there. 15:35.440 --> 15:37.760 But as you can see, they're not well aligned. 15:37.980 --> 15:38.900 This is going to be 15:43.700 --> 15:46.860 the entry point for programming your badge. 15:46.860 --> 15:50.680 If you don't want to use the NFC tools application. 15:50.780 --> 15:53.780 All right, the NFC tools application is very full feature. 15:53.780 --> 15:56.020 They've worked on it for years, three, four years, I think. 15:56.020 --> 16:01.020 So they have all of the functionality that you could wish for in the NFC tools application. 16:01.020 --> 16:20.140 And what we're doing here is trying to just very specifically implement the features that some of these villages, like for example, the biohacking village and Monero village might want to see in their badge in their, you know, inter-village badge. 16:20.460 --> 16:29.960 So, so I'll go back to that in just a minute, but I'd like to, I'd like to draw some things. 16:29.960 --> 16:40.140 So I'm going to get a new piece of paper to explain how this will look once, once we get it working as we want it to. 16:42.460 --> 16:44.900 Is this making sense to you? 16:45.400 --> 16:48.900 I don't know what this person... 16:49.380 --> 16:50.040 Interesting. 16:50.040 --> 16:53.700 There's no name attached to this. 16:53.700 --> 17:04.260 So if this is, if you have a specific question and you can ask it, but this is the, this is the Bob website. 17:04.400 --> 17:06.860 We're doing high tech slides today. 17:06.900 --> 17:13.380 So what you see here is really an elective paper thin e-paper electronic device, right? 17:13.380 --> 17:14.940 It has a battery connected. 17:14.940 --> 17:17.540 This is, this is really high tech folks. 17:17.540 --> 17:19.460 It only looks like paper. 17:19.460 --> 17:22.980 It's not really, it's really, it's, this is high, high tech. 17:22.980 --> 17:23.820 This is high tech. 17:23.820 --> 17:24.500 Okay. 17:24.500 --> 17:25.180 All right. 17:25.180 --> 17:27.700 So this is a Bob website slide. 17:27.700 --> 17:30.640 And you're seeing this created by me live. 17:30.920 --> 17:31.560 All right. 17:31.560 --> 17:39.460 So the Bob website, we took a look at it on the web browser before, and we've got the thing over there. 17:40.440 --> 17:42.940 This is a start. 17:43.900 --> 17:46.520 And this is network. 17:46.520 --> 17:50.100 The rest of them, this is status, help, and so on. 17:50.100 --> 17:53.540 We've got a few things up here, like expert mode. 17:56.760 --> 17:57.800 You read that okay? 17:57.800 --> 17:59.040 I think it's okay. 17:59.640 --> 17:59.900 So. 18:01.540 --> 18:05.580 So start is going to give you choices for... 18:05.580 --> 18:07.620 Maybe I should... 18:08.920 --> 18:11.160 Some of the fine things. 18:11.260 --> 18:13.000 So start is going to give you 18:17.260 --> 18:18.140 village choices. 18:18.140 --> 18:20.420 We've got Monero, we've got biohacking. 18:21.420 --> 18:24.160 We've got rogues, you get the idea. 18:26.840 --> 18:29.960 So I'm going to check off biohacking and Monero. 18:29.960 --> 18:31.620 Those are my two favorite. 18:33.020 --> 18:39.040 And at the bottom, then we're going to have three buttons, we're going to have... 18:40.880 --> 18:44.060 So this is kind of, this is approximate, right? 18:56.840 --> 18:58.380 I think you can read that. 18:58.380 --> 18:59.600 Can you read that Rerar? 18:59.600 --> 19:01.220 Is Rerar even here? 19:03.420 --> 19:07.300 What happens when you go to school and you miss your class Rerar? 19:07.300 --> 19:09.660 I think we'll have to take points off. 19:11.020 --> 19:19.460 So the whole idea of this start menu item is that this is where we're going to be able to write and read profiles. 19:19.460 --> 19:28.440 If we're unhappy with the factory default profile, which is really generic, it doesn't have any village identifiers at all. 19:28.440 --> 19:33.820 It's basically an FUD, which we can even see here. 19:33.820 --> 19:35.760 Let's quickly... 19:35.760 --> 19:37.220 This could be interesting. 19:37.220 --> 19:40.620 I'll take a better, better get a badge that's working. 19:40.680 --> 19:44.600 So I'm going to use the NFC tools application. 19:44.600 --> 19:49.000 And then I'm going to push the star button this time. 19:49.000 --> 19:51.840 All right, push the star button. 19:54.880 --> 19:58.720 All right, so here we have an FUD. 19:58.720 --> 20:01.520 FUD, what does that stand for, Justin? 20:01.660 --> 20:03.200 You don't know? 20:03.200 --> 20:04.460 AJS, do you know? 20:04.460 --> 20:13.400 Okay, FUD stands for Factory Unique Dentifier. 20:13.740 --> 20:14.400 All right. 20:15.140 --> 20:17.140 So FUI just doesn't do it for me. 20:17.140 --> 20:18.380 I needed FUD. 20:18.600 --> 20:22.680 And to do that, we need to call it Factory Unique Dentifier. 20:23.100 --> 20:32.940 All right, so that's what's programmed into most of these badges, except for the middle one, the moon, which comes out of the factory with the game. 20:36.580 --> 20:43.520 So if you look at the record zero there, the data, that's what's programmed into the moons. 20:43.520 --> 20:44.180 Okay. 20:44.220 --> 20:51.340 And if I didn't have this application running, then it would go right to the website. 20:51.340 --> 20:54.220 So let's keep that in mind. 20:54.220 --> 20:59.940 We can consider that when we're thinking of how this start menu works. 20:59.940 --> 21:07.160 So I click on read and the profile that comes up, it's going to say something like factory profile. 21:09.260 --> 21:11.600 With a FUD identifier. 21:11.600 --> 21:12.320 All right. 21:12.320 --> 21:14.880 Now what happens if we're not happy with this? 21:14.880 --> 21:19.960 We then check our villages, the ones that we like the most, we can check more than one, hopefully. 21:20.680 --> 21:27.540 And then click right, and this writes a new profile. 21:28.400 --> 21:37.420 All right, so after we click Monero and biohacking and click right, we will need to place the badge against the phone. 21:38.260 --> 21:46.460 Push one of the three buttons and your new profile will be written to the location in question, the one that you pushed. 21:46.460 --> 21:50.620 If you want to write a profile to the sun, you push the sun, you know what I mean. 21:50.620 --> 22:05.640 You could do the sun, you could do Monero alone, you could do moon for just Rogues Village alone, and the star could program Red Team, IoT, biohacking, and wireless. 22:05.880 --> 22:09.540 No, wait a minute, crypto privacy, they're kind of on board as well. 22:09.540 --> 22:17.180 All right, so that's the whole idea behind this custom tailored application. 22:17.180 --> 22:21.540 Kind of making it easier for you to hop on to the what? 22:21.680 --> 22:25.060 To the village, to the intervillage network. 22:25.280 --> 22:27.140 All right, so how's that going to work? 22:27.140 --> 22:28.960 I'm going to use a different page. 22:29.180 --> 22:31.920 Just check quickly for a Discord question. 22:32.800 --> 22:35.120 All right, so I'm going to go to a different page. 22:35.120 --> 22:38.560 This was explaining the start menu button. 22:39.300 --> 22:42.920 Now we're going to talk about the Bob website. 22:49.180 --> 22:53.480 And we'll focus on... 22:54.200 --> 22:57.840 Is this marker on paper working for you, Justin? 22:57.840 --> 23:01.360 Because this is, this is for you. 23:01.800 --> 23:04.180 So this is a website. 23:05.720 --> 23:08.900 And we've got start up here. 23:09.560 --> 23:12.980 And then we've got net. 23:12.980 --> 23:16.460 It actually says network, I think you get the idea. 23:16.760 --> 23:18.920 Now we've got a few more down here. 23:19.300 --> 23:22.740 All right, so this one is what we're talking about now. 23:23.260 --> 23:29.000 And let me see what it was. 23:29.720 --> 23:31.000 Oh, yeah. 23:31.120 --> 23:39.020 Okay, so according to my memory, because I don't have my notes, we're going to have a few different commands for the network. 23:39.020 --> 23:43.840 This is the backend network that connects the different villages that are participating. 23:44.040 --> 23:52.100 This may have a proxy, a bridge to Discord, to IRC, to some other networks like that, but really it's based on MQTT. 23:52.840 --> 24:01.260 So when everything is broken as, for example, I've heard, we heard from the PHV, the Packet Hacking Village that Discord is having some problems that they're working on. 24:01.260 --> 24:12.560 When all of the networks are broken and not working, as long as you have IP connectivity to our MQTT network, then these commands will still function. 24:13.120 --> 24:16.240 Right, the other things are just kind of bridges, which are optional. 24:17.500 --> 24:28.380 But for the village network, we will have these commands. 24:28.380 --> 24:34.900 We will have, first of all, sorry. 24:35.780 --> 24:36.780 Sorry. 24:36.780 --> 24:38.960 So first of all, we will have connect. 24:40.540 --> 24:44.520 This will simply do a ping out to the network. 24:44.520 --> 24:53.860 And if there is no return to the ping, it means that you're like, you're mobile and your battery's dead or, you know, you're in airplane mode, something like that. 24:53.860 --> 24:55.520 So we connect to the network. 24:55.520 --> 24:58.220 The next one will be authenticate. 24:59.000 --> 25:00.500 This is optional. 25:00.500 --> 25:09.080 Maybe some networks, I'm sorry, some channels or network topics are simply there for test purposes. 25:09.080 --> 25:10.540 You don't need to authenticate. 25:10.540 --> 25:12.540 So in some cases, you do need to authenticate. 25:12.540 --> 25:13.900 In others, you don't. 25:13.900 --> 25:20.240 I think authentication is maybe relevant when we need to have a unique user so that people can talk to each other. 25:20.240 --> 25:24.240 Just like modeled after IP itself, the internet protocol, right? 25:24.240 --> 25:28.580 Different nodes, computers, devices, objects on the internet protocol network. 25:28.580 --> 25:35.020 They can't talk to one another if they're not assigned a unique number, which is called IP number. 25:35.020 --> 25:36.660 So we'll have a similar thing here. 25:36.660 --> 25:44.060 In fact, that's why at the factory we program these factory unique identifiers. 25:45.040 --> 25:52.560 And once we, once we, so, so, let's see. 25:53.200 --> 26:14.920 So once we use the start and write our own unique identifiers, like we were big fans of biohacking, for example, so we use the biohacking write data, it will no longer be a factory unique identifier, it will then be a, starts with S, it will then be a sensitive , 26:14.920 --> 26:23.140 unique identifier, no, S-U-I, sensitive, unique identifier. 26:23.140 --> 26:27.960 Imagine that, we'll say the word as is it written in the dictionary. 26:28.220 --> 26:34.640 Alright, so the S-U-I will lead you to these numbers which you can authenticate with. 26:34.960 --> 26:39.860 Alright, so the third command will be knock. 26:44.300 --> 26:49.560 And this basically takes a parameter, an argument we want to knock on. 26:49.580 --> 26:55.100 I don't know how we're going to code these arguments, probably as buttons, because this is all HTML. 26:55.400 --> 27:00.280 But we'll probably be able to knock on the, what's a good village? 27:04.120 --> 27:06.140 Intrusion detection village. 27:07.160 --> 27:12.720 ID, IDV, which doesn't exist in safe mode this year. 27:12.720 --> 27:15.600 It's a good village to choose, isn't it. 27:15.600 --> 27:26.880 So we're going to knock on a village door, and assuming that they have not locked the door, or that the Discord channel is not set to close, then this automatically opens the door. 27:26.880 --> 27:30.560 So you kind of understand where this system is headed. 27:31.800 --> 27:36.680 This is what is commonly known as, let me just find it. 27:36.680 --> 27:38.320 It's on the other side. 27:38.320 --> 27:55.740 So this is what's commonly known as a village network story, kind of a gentle gamified step by step type of introduction to the intervillage network using badges. 27:55.740 --> 27:58.740 Okay, but this is not my decision where this is all headed. 27:58.740 --> 28:05.600 This could go anywhere, anybody can influence how this story appears. 28:05.600 --> 28:23.060 In fact, my original idea, folks, which we had to cancel because too few people were interested, was to make a kid's version, a kid's story, something like memory with, you know, dogs, cats, rock players, guitars, things that kids like. 28:23.060 --> 28:31.960 So there was a kid's story, which is slightly different than this, but made sense to those young hackers under 15. 28:31.960 --> 28:40.140 So if you're a hacker, that's only 8, 9, 10 years old, you should have a service from us that represents your interests. 28:40.140 --> 28:41.160 That's my opinion. 28:41.160 --> 28:47.920 Okay, so I was really interested in having a kid's story, which didn't work, so we'll probably get it done next year. 28:47.920 --> 28:50.160 But we had to cancel it for this year. 28:50.340 --> 28:53.480 And in this year's version, we just have these two. 28:53.480 --> 29:01.300 We have the Rogues Village game, and then we have the portal that allows you to choose profiles. 29:02.660 --> 29:04.460 Right, and so what comes after knock? 29:04.460 --> 29:14.020 What traditionally happens after you knock on a door, the door opens, because it's automatic, you know, no human is there, but you can go in the door. 29:14.020 --> 29:18.760 Or a human is standing there, you know, maybe the human wants to know what you want. 29:18.760 --> 29:20.180 They're saying, what's your name? 29:20.180 --> 29:21.680 Do you have permission to enter? 29:21.680 --> 29:22.820 These types of things. 29:22.960 --> 29:26.180 So any command that could follow here is kind of up to you and me. 29:26.180 --> 29:27.580 It's our imagination. 29:28.880 --> 29:35.080 And I'll tell you, it's quite a lot of fun to design and implement a whole new network using all of these opcodes, right? 29:35.080 --> 29:39.560 Especially if the job is easy, because you're limiting this to like a half dozen opcodes. 29:39.560 --> 29:43.940 And so I don't think it will be too difficult. 29:44.120 --> 29:45.740 But the bad news is, so that's the good news. 29:45.740 --> 29:48.480 The bad news is that this just isn't finished yet. 29:48.820 --> 29:56.140 Yeah, I was working until the last minute, soldering and pasting, adhering, creating these hardware devices. 29:56.440 --> 29:57.940 So that's why I didn't get to this. 29:57.940 --> 30:01.120 And the other people who said they would get to this kind of didn't either. 30:01.240 --> 30:04.540 So that's why it's not well... 30:04.540 --> 30:07.980 It is well designed, but it's not well tested. 30:07.980 --> 30:11.660 So the things that we have working, they're kind of in different pieces. 30:12.240 --> 30:17.140 And there is like, the checkboxes are on one page. 30:17.140 --> 30:23.340 And then there's a tab, which doesn't belong in this user interface. 30:23.340 --> 30:25.820 And the tab was giving us right. 30:25.840 --> 30:28.920 And then there's another place, which is a button for read. 30:28.920 --> 30:32.540 So that's why you're not seeing this because it's just too poorly organized. 30:32.540 --> 30:38.840 And the part that is well organized, which is on the website running right now. 30:39.160 --> 30:41.080 That's this thing here. 30:42.340 --> 30:52.700 There's a, there's a little bit of eye candy there from Andres, so it's really nice stuff. 30:53.180 --> 31:01.580 And this is the part that's well organized, you know, it's got fading in and out and things and illustrations. 31:01.880 --> 31:05.760 However, it doesn't have the functionality. 31:05.760 --> 31:07.680 So we've got to combine these things. 31:07.680 --> 31:08.160 Right. 31:08.600 --> 31:12.660 It might be worth, it might be worth mentioning. 31:14.940 --> 31:17.080 There is a connection here as well. 31:17.080 --> 31:26.380 You know, if you're interested in using a hardware badge, the one that actually is in circulation, there's a few different places you can find them and I think this is working. 31:26.380 --> 31:27.860 I'm actually not sure. 31:29.040 --> 31:30.580 Let's check this out. 31:31.210 --> 31:33.340 Alright, so that's hack five. 31:33.340 --> 31:37.240 That's the one place you can find the black badges. 31:40.240 --> 31:44.660 This is kind of testing in action, real time. 31:44.660 --> 31:55.240 Here is a Cypher market, the premier place for Monero merchandise, everything from shirts to stickers to badges. 31:55.240 --> 32:01.580 Alright, so here you can get more than just the black badges, you can receive, you can get all these these different colors. 32:02.160 --> 32:03.080 All right. 32:03.820 --> 32:08.480 And let's see what's the very last one is the factory store. 32:09.920 --> 32:11.220 How do I get to that. 32:11.220 --> 32:12.360 Okay, here. 32:12.420 --> 32:26.400 And this is a different yet a different store where you can find things like last year's Monero Ising badge, for example, I got a few of these done I think there's five or six which are ready to go. 32:26.700 --> 32:28.180 Not very many. 32:28.780 --> 32:46.960 And another thing that's maybe interesting because this is commonly confused I think it's only, and I couldn't convince other folks to carry this so this is the DIY the do it yourself version, which looks like this, it doesn't have a enclosure, and you have to put the parts together yourself. 32:46.960 --> 33:00.140 So it's much more inexpensive, and it gives you an option to really look at the circuits before the leather comes onto it, which can be an advantage. 33:00.760 --> 33:04.880 Right, so that's the only place to get the DIY badges. 33:05.240 --> 33:06.980 And that's up here. 33:07.680 --> 33:08.880 The. 33:09.280 --> 33:20.180 So because the start ops and the read write buttons are not connected to actual JavaScript which does those operations. 33:21.540 --> 33:26.800 We'll have to use NFC tools during this office hours during this badge clinic. 33:26.800 --> 33:32.280 What I also want to mention is that. 33:33.060 --> 33:35.560 Is it here, it's still not here. 33:36.020 --> 33:37.300 Unfortunately. 33:38.980 --> 33:41.200 Unfortunately, okay so. 33:45.680 --> 33:55.840 Yeah, so unfortunately, there is something you need to do in order to use phones with. 33:55.840 --> 34:01.080 I'm sorry not phones but websites with the village badge. 34:02.340 --> 34:11.620 The Chrome team had a program, I won't make it a long story, but a program that ended on July the 29th. 34:11.780 --> 34:17.560 Really nice guys right to end the program, the thing that we really need to use. 34:17.760 --> 34:22.440 On the 29th, could they not wait a week or two. 34:22.440 --> 34:29.420 No, they ended it on the 29th, which means that you need to do, you need to jump through hoops in order to use a web browser. 34:30.620 --> 34:34.760 With, with anything that's NFC powered. 34:36.720 --> 34:39.520 I can do this on the on the larger. 34:39.520 --> 34:49.040 So I will go through the steps now just, just in case it gets confusing later you do have this demonstration then. 34:49.040 --> 34:54.260 So this is going to be well documented here in the welcome part of the site. 34:54.260 --> 34:55.140 Okay. 34:55.680 --> 34:57.720 But the thing that you need to do. 34:57.720 --> 35:04.300 I thought I had this somewhere, but it caught me off guard that they ended the program on the 29th. 35:04.660 --> 35:15.760 So the first thing is unfortunately Firefox hasn't been able to make it work, and all the Apple things they've decided they don't like NFC at all in their websites. 35:16.380 --> 35:23.700 So, so this is Apple that I think it took them eight years to put an NFC circuit in their phones. 35:23.700 --> 35:31.900 So it might take them very, very long time folks I would not wait for Apple to actually start implementing the things that are available in Android today. 35:32.620 --> 35:36.840 So if you type on version, you can see what version of Chrome you're using. 35:37.840 --> 35:40.720 And what we really want is flags. 35:43.140 --> 35:45.280 Okay, do you see that URL there. 35:45.620 --> 35:47.360 Chrome flags at the top. 35:47.940 --> 35:51.360 Okay, this is all what this is in German I'm sorry about that. 35:51.960 --> 36:08.080 But it's clear enough because lots of stuff here is in English, so I'm just going to leave the German stuff up here basically says, be careful warning these are experimental features, only turn them off, only turn them on if you know what you're doing. 36:08.180 --> 36:13.720 So we're going to search for, I think it's called something platform. 36:13.720 --> 36:15.060 There it is. 36:15.060 --> 36:17.380 Alright, so I just had to search for platform. 36:17.440 --> 36:20.940 And there's a few things that come up, but the very first one. 36:20.940 --> 36:22.160 This one here. 36:23.020 --> 36:25.340 Experimental web platform features. 36:25.580 --> 36:34.040 So this is disabled, because in my case I'm using a computer, a big computer that has no NFC circuit. 36:34.160 --> 36:36.060 That's why I don't need this. 36:36.060 --> 36:39.520 But if I do enable this, just like this. 36:39.560 --> 36:44.900 And then I relaunch, I'm not going to relaunch folks but you know you understand that the procedure here. 36:45.080 --> 36:51.520 And this will be enabled and if it's on a running on a phone any device with an NFC circuit. 36:52.100 --> 37:01.940 That's when you can start to use NFC from your phone in a website, together with your intervillage badge. 37:01.980 --> 37:04.580 I hope I explained that well enough. 37:05.280 --> 37:08.700 I'm going to look and see if there's any questions about it. 37:10.280 --> 37:12.220 Seems there's not. 37:12.280 --> 37:14.920 Unless it's up here on general. 37:15.760 --> 37:18.240 Let me check the general text. 37:20.180 --> 37:21.880 Alright, so everything's fine. 37:21.880 --> 37:28.060 If you're watching and you kind of got the picture about this, where you're going to need this turned on. 37:28.060 --> 37:34.840 Unless the Chrome team re-enables the NFC for certain sites. 37:36.000 --> 37:40.720 All right, and after you do this with the Chrome flags, then you can go to Bob. 37:41.550 --> 37:59.500 The website is there but it's not hooked into the NFC JavaScript features which you'll probably want to use and probably want to onboard to your village of choice, like the Monero village or the Rogues village, Red Team, crypto privacy, all of these different villages that are participating, 37:59.500 --> 38:03.020 like biohacking and IoT. 38:03.020 --> 38:05.960 You can first read data if you're feeling a bit. 38:06.460 --> 38:08.140 If you're feeling a bit. 38:08.140 --> 38:11.300 If you want to test it to know if your badge is working. 38:11.300 --> 38:13.340 And once you do that there will be a... 38:13.960 --> 38:18.920 There will be text that comes below that telling you which profile you have. 38:19.180 --> 38:26.400 Probably it has the factory default profile with FUDs, the factory unique identifiers. 38:26.400 --> 38:31.780 All right, then write data will simply write what you have selected in onboard village. 38:31.780 --> 38:40.000 So if you have all of the villages selected, which means biohacking, Rogues village, Monero village, Red Team, IoT, crypto privacy. 38:40.000 --> 38:41.240 Is that the name? 38:41.240 --> 38:45.520 I think it is the name cryptography and privacy village. 38:45.520 --> 38:57.780 So that's when your write data will simply write unique identifiers which are SUIs, sensitive unique identifiers to your badge for all of those different villages. 38:57.780 --> 39:13.000 All right, so that's kind of the cheap way to describe and demonstrate what happens with the BOB application, which is the main website for the intervillage badge this year. 39:13.000 --> 39:19.000 All right, that's the website, the homepage and the portal for making everything work over JavaScript. 39:19.000 --> 39:28.460 Don't forget that you need to turn on the NFC Chrome feature, the experimental platform, in order to use the BOB website correctly. 39:29.560 --> 39:31.460 Until the 29th, you didn't have to. 39:31.460 --> 39:32.460 And right now you do. 39:32.460 --> 39:37.620 Who knows if in another week or so, the Chrome team will make that work again. 39:37.620 --> 39:46.620 And if we're really lucky, then in less than five years, Apple will actually make NFC available to people using Apple devices with websites. 39:46.620 --> 39:49.960 All right, so that's what we have here. 39:49.980 --> 40:06.300 We're going to be able to connect to the backend, to the MQTT network, we're going to be able to authenticate with our FUD or our unique identifier. 40:06.900 --> 40:08.060 What is it? 40:08.300 --> 40:09.960 Sensitive unique identifier. 40:09.960 --> 40:10.880 That's it. 40:10.880 --> 40:19.760 So that's how that's going to work, authenticate, and if we just provide nothing at all, then we will have access to some of the test channels. 40:20.100 --> 40:32.240 And then we can knock on a village, and if it maps to a village, a real village name that's on Discord, there will probably be a bridge, which will then write a knock knock message to that village. 40:32.240 --> 40:39.260 In fact, if you look on the Monero villages channels, you will find one that's called mv-proxy. 40:39.260 --> 40:41.220 And that proxy channel. 40:41.220 --> 40:44.920 Okay, I'll finish the sentence mv-proxy-text. 40:44.920 --> 40:46.380 Okay, it's a text channel. 40:46.440 --> 40:58.900 And what that is intended for is are these type of applications, you know, bots and automated applications that work with the Discord channel system. 40:58.900 --> 41:08.240 AJS had a very, very, well, he does have a very, very nice and interesting bot that is a tip bot. 41:08.560 --> 41:17.020 The reason for that is very similar story to Chrome teams deciding to block NFC on the 29th of July. 41:17.140 --> 41:28.280 The folks that are running Discord for us, they're doing a great job, we're very grateful and thankful that they're running and maintaining Discord channels for DEF CON. 41:28.280 --> 41:31.420 They just couldn't get all of the bots online. 41:31.420 --> 41:32.600 It was too much. 41:32.600 --> 41:41.960 It was just too much work and too high a risk without being able to be certain that every bot was doing as they were told, right. 41:41.980 --> 41:46.520 So they kind of, they kind of canceled the bot system. 41:46.520 --> 41:52.960 That's why we couldn't get AJS's tip bot onto our proxy channel. 41:53.260 --> 41:54.960 How can I... 41:54.960 --> 42:02.940 Yeah, it's too... I wonder if I can very quickly add a source in OBS show you these channel names. 42:03.720 --> 42:05.460 This will be kind of difficult. 42:05.460 --> 42:07.600 I'm not going to be able to do it in time. 42:07.720 --> 42:14.700 In any case, this will simply be another application running through these proxy channels. 42:14.860 --> 42:23.780 And that's the best answer I have to the question that we got before about could you demonstrate the Bob application, right. 42:23.780 --> 42:27.820 So not all of this is, is working completely. 42:27.820 --> 42:33.980 The hardware is complete, everything is finished from the membrane overlays that's in the front. 42:34.340 --> 42:38.580 The embossed places, full color. 42:38.580 --> 42:42.920 On top of that the parts inside, which look like this. 42:43.960 --> 42:48.420 And basically everything's finished with the hardware, just not the software. 42:48.420 --> 42:50.580 The backend system is kind of working. 42:50.580 --> 42:56.200 I mean, it's working great, but it's just not very, very rich, very primitive system. 42:56.680 --> 43:02.600 Alright, so what we can do is take a look maybe under the microscope at some of these things now. 43:03.120 --> 43:09.500 Just to change, switch gears a bit from this that we had before. 43:10.540 --> 43:13.540 So I'll find a blank piece of paper. 43:13.760 --> 43:28.620 I'm sorry, blank piece of electronic EPD high tech, cutting edge, foldable screen, multi thousand euro devices. 43:30.540 --> 43:32.940 There is a badge, this is a prototype. 43:33.500 --> 43:45.880 And what you can do if, for example, especially if you pick up one of the DIY, the cheapest models, which, which, which when you get it out of the box, it looks like this. 43:45.880 --> 43:46.920 It is here. 43:46.920 --> 43:47.920 Okay, there we go. 43:47.920 --> 43:49.380 You can see that pretty well. 43:49.380 --> 43:51.680 So it is assembled for you. 43:51.680 --> 43:56.140 And the reason is that some of those parts on there are very, very small. 43:56.140 --> 44:04.240 Okay, so it just wouldn't make any sense at all to send a package of parts which you need to very carefully put down with tape. 44:04.240 --> 44:07.120 Get the contacts right with these dome switches. 44:08.120 --> 44:14.080 And the ICs that are involved there that just will, they're two by three millimeters large. 44:14.080 --> 44:29.680 Okay, and if you can imagine like these, these dome switches they just slide around as you can see they go all over the place you've got to perfectly align all three without the use of tools and then get the right kind of tape on there that's trapezoidal shape and then put, 44:29.680 --> 44:33.680 you know, avoid the, avoid the through hole gold contacts. 44:33.680 --> 44:40.000 So a lot of that stuff I just thought it would be probably too difficult, especially soldering these parts. 44:40.000 --> 44:46.980 So this is how your do-it-yourself kit arrives, you receive this, you receive. 44:49.280 --> 44:55.240 So my workplace here it's just a big mess and I'm not seeing where. 44:55.660 --> 44:57.220 Oh here I found it. 44:57.560 --> 45:01.920 It's a small miracle but I found a do-it-yourself kit. 45:01.920 --> 45:05.580 So you get a front overlay. 45:06.640 --> 45:09.160 I can't get the light just right here. 45:09.320 --> 45:15.680 But you can tell this is a overlay with a adhesive back, right, and you get there are two pieces. 45:16.440 --> 45:23.300 So there's a, there's a piece of leather which this is all adhesive so you don't need to mess around with glue. 45:23.300 --> 45:25.520 No glue and no tools required. 45:25.520 --> 45:27.420 This is really for novice users. 45:27.420 --> 45:34.420 If you want to assemble your own PCB, you can probably do that. 45:34.420 --> 45:41.760 In fact, I don't know if this is secret or not, the very first hundred devices that we sold. 45:42.280 --> 45:47.180 They had, they included a bare PCB with no parts at all. 45:47.180 --> 45:50.020 So I was thinking, will people assemble them? 45:50.020 --> 45:51.320 Probably not. 45:51.320 --> 46:01.860 But if you were one of the lucky first hundred then you got a bare PCB, and I guess you know, I don't know how to distribute them because it's all going by post now but I have no problem. 46:01.860 --> 46:04.680 I have enough bare PCBs if other people want those. 46:05.180 --> 46:11.060 Just have to let me know, tell me and we'll have to discuss and figure out a way to distribute them to you. 46:11.340 --> 46:14.500 So while I was talking about these very small pieces. 46:14.500 --> 46:20.620 I think I can finally demonstrate because we do have a microscope now. 46:20.620 --> 46:25.380 Just have to switch to the microscope screen. 46:26.280 --> 46:37.460 Alright, so let's just start with a... let's start with the back of a... 46:38.500 --> 46:41.920 This is a Monero Rising. 46:43.020 --> 46:46.260 I'm not sure where it says rising, you will just have to trust me. 46:46.260 --> 46:47.840 This is how the front looks. 46:50.320 --> 46:53.720 So there you can see that it is truly a Monero Rising. 46:55.260 --> 47:03.560 There's always a problem with microscopes, with document cameras, you can have it big, you can have it small, but you can't have both. 47:05.060 --> 47:07.260 So okay, here are some of the parts. 47:08.100 --> 47:18.300 There is the PMIC, the power management IC that belongs on the Monero Rising, which controls all of the various lights. 47:18.300 --> 47:20.040 Here's the microcontroller. 47:21.280 --> 47:26.600 Alright, so now we're going to take a look at the size in comparison. 47:28.480 --> 47:30.700 Maybe I'll have to focus a bit. 47:31.460 --> 47:44.760 In comparison to the very standard size microcontroller, here is the size of the NFC EEPROMs that we're using this year. 47:45.440 --> 47:46.940 You see the difference? 47:47.700 --> 47:49.020 It's giant. 47:49.020 --> 47:53.460 And even that one microcontroller is really not that big. 47:54.380 --> 47:55.500 Right. 47:55.500 --> 47:57.760 So let me just take this over here. 47:58.740 --> 48:00.620 This is what we were just looking at. 48:02.060 --> 48:03.740 Can you see the microcontroller? 48:03.740 --> 48:05.920 Can you identify the part that we were just looking at? 48:05.920 --> 48:10.400 Well, not if it's not in focus, but if it is focused... 48:11.480 --> 48:13.000 Put my finger on there. 48:14.760 --> 48:16.140 There we go, now it's focused. 48:16.700 --> 48:19.600 So the microcontroller that we were just looking at is right here. 48:19.600 --> 48:21.660 It's really not a very large piece. 48:22.600 --> 48:29.960 And if we compare that with the parts that are on this year's badge, they're very, very small. 48:29.960 --> 48:31.920 Alright, so I keep saying it's small and small and small. 48:31.920 --> 48:33.380 You get the point, right? 48:34.560 --> 48:36.460 We can go back to the microscope. 48:38.700 --> 48:40.880 And look at some of the other things. 48:40.940 --> 48:42.800 Microscopes are always very intriguing. 48:42.800 --> 48:47.680 So it's a very simple system this year. 48:47.680 --> 48:51.580 We don't have 100 or 120 parts as we did last year. 48:52.620 --> 48:54.620 You can see the traces. 48:56.200 --> 49:01.000 All of the schematics, which means where these traces go. 49:01.280 --> 49:04.000 Here's a tip of a ballpoint pen. 49:04.000 --> 49:09.480 So all of these traces, they're basically connecting legs or parts. 49:09.480 --> 49:10.540 No, not parts. 49:10.540 --> 49:18.150 They're connecting the contacts of these integrated circuits with other things like the antenna, for example. 49:18.540 --> 49:20.120 You see a hole here. 49:20.120 --> 49:21.180 This is quite interesting. 49:21.180 --> 49:23.020 This is called a via. 49:23.500 --> 49:27.480 And this via simply traverses the board. 49:27.480 --> 49:31.740 Because the board is 1.6 millimeters thick. 49:31.740 --> 49:33.200 Is that how thick they are? 49:33.200 --> 49:34.740 Yeah, 1.6 millimeters. 49:34.960 --> 49:37.380 And it goes to the bottom. 49:37.380 --> 49:43.300 And if we turn the board over, which I'll do quickly now, we can see holes on the bottom as well. 49:43.300 --> 49:50.280 So basically, that via is connecting a track from the bottom to the top. 49:51.340 --> 49:53.140 Right, so that's what vias do. 49:53.140 --> 49:55.840 And that's how we connect the different parts together. 49:55.840 --> 50:01.660 And if you want to be a hardware hacker and solder some headers on to this, I did make a mistake. 50:01.660 --> 50:07.300 I made them separated only, what, they're two millimeters apart. 50:07.300 --> 50:09.540 They should be 1.27. 50:10.520 --> 50:16.920 So I kind of, there's a few mistakes that will cause you a few headaches, but you can still solder headers on there. 50:16.920 --> 50:22.160 They just won't line up to the traditional, what, Arduino and breadboards. 50:22.280 --> 50:25.620 So here is the, that's really fine etching, isn't it? 50:25.620 --> 50:28.800 So one of our subcontractors did a good job this year, the etchers. 50:29.340 --> 50:31.300 And this is the antenna. 50:31.940 --> 50:36.460 Right, and you can see where the antenna connects to the front, because somewhere there must be a what? 50:36.600 --> 50:37.360 A hole. 50:37.360 --> 50:38.400 It's called a via. 50:38.820 --> 50:39.980 And there it is. 50:40.200 --> 50:42.260 So this hole is connecting to the front. 50:42.260 --> 50:46.460 And in this manner, we're getting the, now I just put some ink on there. 50:47.440 --> 50:57.980 And in this manner, we're getting the antenna, which is on the back, going to a track, which is on the front, connected to these three parts. 50:57.980 --> 51:02.140 U1, U2, and U3. 51:02.140 --> 51:08.840 And those U1, U2, and U3 connect to, can you guess? 51:09.200 --> 51:10.980 To these. 51:10.980 --> 51:17.720 Okay, it doesn't make sense to use a microscope for already very large things. 51:17.720 --> 51:29.040 And those three EEPROMs, integrated circuits, which you can actually see, because we made the windows, we made the front overlay transparent. 51:29.040 --> 51:32.580 We put windows in so you can see your electronics. 51:32.920 --> 51:39.320 I mean, you could chip away the plastic and connect taps to the legs of the EEPROMs. 51:39.500 --> 51:41.580 But I don't know, I don't recommend that. 51:41.580 --> 51:43.360 So anyway, that's how you do this. 51:43.360 --> 51:49.360 So as a last demonstration, before we end, because we're getting close to the end, aren't we, Justin? 51:49.360 --> 51:50.840 And there are no more questions. 51:50.840 --> 51:59.140 So last demonstration, I will show you how I write information to my badges. 52:00.200 --> 52:06.320 So I'm going to go away from the browser and I'm going to use NFC tools. 52:06.480 --> 52:09.920 You can do pro or tools, doesn't matter which one. 52:09.920 --> 52:10.600 All right. 52:10.600 --> 52:11.940 So I'm going to do write. 52:12.640 --> 52:14.140 I'm going to add a record. 52:14.940 --> 52:16.120 Going to do a URL. 52:16.120 --> 52:17.400 Did you see all of the different? 52:17.400 --> 52:21.720 I mean, this is all the things that you can do with a badge. 52:21.720 --> 52:24.020 You can even put a Bitcoin address on there. 52:24.160 --> 52:27.820 This is what most people will probably do in the Monero village. 52:28.760 --> 52:29.260 All right. 52:29.260 --> 52:30.380 That was a joke, by the way. 52:30.380 --> 52:33.120 OK, so you can put your your email address on there. 52:33.120 --> 52:34.880 You can do and you can do multiple. 52:34.980 --> 52:35.300 All right. 52:35.300 --> 52:36.620 So I'm going to do a demonstration. 52:36.620 --> 52:38.000 I'm going to put a URI. 52:38.000 --> 52:40.100 I'm going to choose HTTPS. 52:40.120 --> 52:44.720 I'm going to choose RERAR's excellent website. 52:47.260 --> 52:51.980 RERAR, is it an excellent website or is this just kind of a half, not very good website?
