3720	5280	Okay, guys.
7000	14140	But we will start the next presentation, which is called This Year's Village Badge.
14320	20960	My name is Michael Schloff von Benevitz, and I believe that our AV is working very well.
20960	29000	Thanks so much to SGP and to AGS. And let me just get started with this.
29000	33660	We have some interesting devices to take a look at.
36700	39100	To begin with, we have...
41640	47500	To begin with, I should turn off my stream so there's no echo. Okay, that's better.
48680	52780	So this is the high-tech slide deck that you may have heard of
52780	56980	with the paper and the pencil. That's how we're doing it this year.
56980	60020	This year's Village Badge.
68640	76040	And what we have here, we've got basically three days. We've got Friday. We've got Saturday.
78140	83360	Let me do this. We've got Friday, we've got Saturday, and we've got Sunday.
83900	92300	So this is where we are. And I'm just explaining this because there's a little bit of organization.
92300	100000	Some people are interested in beginner style, novice topics. Others are into the more advanced stuff.
100000	110900	So we've got this presentation now. Later, we've got another one. It's called Getting Started.
115030	120970	Okay, and in this one, we're going to talk about the construction,
126390	128290	how it's made.
130570	136290	A lot of people have been asking about, can they make it on their own? Is it open source? Are there
136290	143010	design archives? This type of thing. So that's what we're going to do now on Friday in this first
143010	149310	hour. Okay, so we're going to talk about the SCM, the source code management, the open source,
149310	157070	all of the things that you can store on disk, like the design archives. And after this hour
157070	163510	is over, we'll take a short break and we'll have another presentation with me as well. Just like
163510	169230	Rira said before, this is the Michael evening. And we will talk about getting started with the badge.
169230	175230	So this second hour, this will be things like, what is the first thing that I can do once I have
175230	182050	it in my hands? This is the way it looks. So let me just put that on the side. And then we have on
182050	198050	Saturday, I don't have the schedule. Let me make sure I get this right. And Saturday, there we have
198050	214270	it. We have on Saturday, the badge clinic. And this is one full hour. During the badge clinic,
214270	219270	we're going to get into some advanced use. We're going to do things like
226290	232090	impersonation of other devices. We will do examination
235830	238930	of other NDEF formats.
240850	244770	So do you get the point? We're going to do some more advanced stuff here,
244770	250510	but this is like office hours too. So you can ask easy questions if you like.
253330	259210	I hope you can read my writing. Can you read my writing? Can everybody raise your hand
259210	265810	that can read? Oh, you can't? No, you can't? Okay, then I'll just have to write a bit
266450	272070	better. Okay, on Sunday, let me just check. We've got more things happening then.
275130	280490	And Sunday, we have another badge clinic. So let's make a plan for that.
285230	294090	And then this will be a free mic style. We can do anything we want on Sunday. Does that sound
294090	303770	okay with you? Hands, please. So we're going to do on Friday today, a construction, a making of,
303770	308410	and then we'll have a getting started, kind of a novice approach. Tomorrow, Saturday is going to
308410	313750	be a badge clinic. Sunday will be a badge clinic. And tomorrow is where we get kind of more advanced
313750	321190	with interesting things, backup and things like that. All right, so this kind of fell off to the
321190	334930	side. Let's take a look at that. So this is the badge. Let's do this. It's basically a passive
334930	344430	device. You can tell that there are no, there are no connectors on here. There are no batteries.
347040	354160	There are no lights. Obviously, if there are no batteries and no connectors to put energy into
354160	362440	this, right, like voltage, like current and amps, then you're not going to have much possibility
362440	370760	to run, for example, actuators, things that act on the environment, like little fans that move air
370760	377640	or lights that illuminate and emit photons, turn energy into photons. So it doesn't have any
378200	384760	cable connectors, any batteries. There's no batteries inside. If you want to know how
384760	390760	thick this is, let me just put a pen up to here. So this is kind of, you can see approximately
391480	397360	the thickness. There would be possibly space for a very small battery, but it doesn't have one,
397360	401700	trust me. We're going to take it apart soon. This is Friday. So we're going to talk about
401700	407460	the construction and we'll take one completely apart. We will destruct one. No, how do you call
407460	416240	that? We will disassemble, that's the word. We will disassemble one and then reassemble it again.
417220	423040	Okay. So I don't know if the design is so artistic. The pyramid is symbolizes with all
423040	429540	the various bricks. So the bricks are different topics or different things. At first,
429540	434780	they were different NDEF pieces of information. And then there were different villages.
436220	442120	Because after all, this is shared, the work to produce this intervillage badge is shared among
442280	446840	a variety of villages. It's kind of, we're kind of in the middle of it, the Monero village,
446840	453420	but we have a biohacking village, a red team village, IOT village. There is, and I don't want
453420	459940	to miss anybody, but I'm saving the best for last because there is the rogues village as well. And
459940	465860	I'm particularly happy that they've produced a game for this. Maybe we'll get to that, I think,
465860	470500	tomorrow because I haven't figured out the game yet on my own. It really would be better if rogues
470500	481860	village presented that. But let me just write those down. And so we, because after all, this
481860	489880	slide system really is fantastically elegant. So let me just write that down. So these are the
489880	503160	intervillages. We have Monero, we have biohacking,
504200	518560	we have IOT, we have red team, and we have the rogues village.
521200	528980	Okay. All right. So that's kind of what this crazy little pyramid symbolizes. I'm sure everyone in the
528980	535260	world could do better. I'm really no artist there. And the rogues village folks from the rogues chose
535260	545680	these very nice symbols, which are kind of a magical, yeah, magical enrichment to what we're
545680	552560	doing here. Because before they were just numbers. I'm not sure if I have an old badge somewhere.
553000	558780	You do have to be careful. There are a few photographs of old badges floating around.
558780	563220	You look at one, you realize you like it because it has the numbers one, two, three. Well, be careful
563220	569260	with that. The new ones, they don't have numbers. They have these symbols. All right. This is
569260	574920	important for the game as well. These symbols have meaning during the rogues game adventure,
574920	585120	which we'll get to that a bit later. Okay. So let's move to... where's all my paper?
586660	598910	Let's move to components. Oops, that's a G. Let's do components.
602990	609150	Let's do that next. This is a bit unorganized. We could talk about software. We could talk about a
609150	623270	lot of things, but I'm going to talk about the hardware components first, not the parts.
623270	630250	You'll see that in a minute. This is more or less the most important piece.
630250	632710	Let's see if I can go downward.
639520	649930	That zooms in a bit. So what we saw before was this thing here. And this is indeed...
652050	657570	and this is indeed the interior. This is the PCB. So for all those who think, okay,
657570	662310	this thing doesn't look like an electronic device. This is like a piece of plastic.
662310	668990	Looks like a hockey puck. I think, yeah, the Monero hardware team probably just cut it into
669170	675210	a triangle. It's a piece of plastic. So that's not true. It does have electronic circuits.
675410	680530	You can even see the chips if I just get the lighting right. There are some integrated circuits,
680530	686750	some switches, some traces, copper. If I turn it over, you really see that there's an electronic
686750	695670	device because then we have a trace antenna for the radio transceiver inside. And then there's
695670	703570	some hacking things that you can do with that as well. So that's the PCB. Okay. This is how
703570	721480	it looks in the end. This is the finished piece. And this is the PCB. And what else is there?
727400	735140	So we can go back even one more step. We can, let's see if I can remove this carefully.
736460	749950	We can. We can see what the PCB looks like before it's assembled. All right. So
752290	755250	I'm not sure if this works so well, but
757890	766050	so this is, oh, I know what I'm doing wrong. That's what I need to do. There we go. So this
766050	774350	is the panel. You can see that there are four PCBs in here, but they don't have any parts on them.
774350	782010	If they did, they would look like this. See the difference? The parts are so small, in fact,
782010	788330	it's a bit difficult to see them, but there are some parts here, one, two, three,
788330	793270	and then there's one, two, three switches. These are kind of very slim devices.
793390	798670	And this is the PCB as it starts. So let's go back to there.
799770	805250	So that's what we're doing. We're starting with a PCB. We're starting with a PCB.
805870	813490	We put the parts on the PCB, and then we end up with the assembled PCB. And from there,
813490	827060	we're going to do a few other things like make it look like this. See how that's missing the plastic
827060	836700	side? This is really just a PCB sandwiched in a front overlay and a back piece of leather.
837860	842520	You can see one of them is orange and one is black. So now you're probably guessing there
842520	850100	may be other colors as well, which is true. So from the ground up, we have the raw PCB,
850100	857000	the assembled PCB. We place the membrane overlay is the proper name for it.
860140	864560	And membrane overlays look like this. They come in a big sheet.
868330	874950	And you can see that they are very thin. It's basically an adhesive. So I peel this off
877130	878650	and place it
881070	887050	on there. And that's what you get after that. The back is this piece of leather. You can see that
887050	893910	I've cut these out with a laser. So the reason that we're putting leather on the back is because
893910	903790	these badges often rub against other things. You place this back to back on, for example, a phone.
904550	913070	So this is the classic use case. You take a badge, you put it on the phone,
913070	923890	and then when it smacks on the phone there, it's going to scratch your lens unless it has,
923890	928690	for more narrow village badges, right? Because we're using leather, we're using exotic stuff
928690	933610	like front overlays. And so every year is a bit different. This year we have some unique
934230	942770	materials, right? The only thing that's missing is the plastic piece. This is the frame.
943090	949170	This is made from liquid plastic, which is ultraviolet hardened. So it's hard enough.
949170	953670	It's somewhat brittle. If I really pull hard, I can break it. But you get the idea
953670	961070	after you have sandwiched the PCB with a front overlay and the rear leather,
961070	965830	and this is what you put on here to get to complete the device.
967250	973830	It's not really so important to show how this is done properly because the do-it-yourself models
973830	981710	do not come with a plastic frame because it would be very difficult to put on. It's actually,
981710	989090	they usually break. But I got it. Okay, I think I got it. Yeah, you see that? You see,
989090	994650	so this one broke. So that's the reason we're not sending these frames out in an unassembled
994650	999970	manner. I mean, that's an excellent... I don't know. I don't know if that's good or bad, but
999970	1008210	this really proves the point. We have a need for helping people learn and sending do-it-yourself
1008210	1013890	models, which cost us less time. And so they're less expensive. And the reason we didn't do it
1013890	1020270	with a plastic frame is because they're brittle enough that it's very difficult to put them on.
1020290	1025730	And so when we do this in the factory, we're breaking one, we take another one, that one
1025730	1032610	doesn't break. We get our orange one or red one, the green one breaks. And so we're kind of allowed
1032610	1038790	to get sloppy or to make these mistakes in the factory. But if we send one frame out, which with
1038790	1044470	each of these sets, and the poor person, wherever they get it, maybe they're on a ship in the middle
1044470	1049130	of the Atlantic, can't receive post for another three months. They break their frame, then they
1049130	1055230	don't have, you know, it's just not nice. So we are sending do-it-yourself models
1055890	1061830	without these plastic frames. And part of the do-it-yourself system, the approach, it's called
1061830	1068810	you make your own frame. So you can probably order one. I mean, the open source archive shows
1068810	1076030	how to construct the frame. But we prefer that you go, you walk down the street or across the city
1076030	1082890	where you live, go to a hackerspace, a maker lab, where they have machines that can produce plastic
1083610	1089870	parts. And you take the model, you download it off of the internet, where we've stored all of the
1089870	1098690	design, and you produce your own plastic frame. I mean, it's not that difficult. It just,
1098690	1102790	you have to be determined and motivated. And that's how you get a plastic frame
1102790	1109890	if you don't want to receive one purchased in a kit with a badge like this.
1110490	1116950	Right? So I kind of went all the way from the start of the unassembled board
1117890	1120570	to the assembled device now.
1121590	1128190	The intermediate steps like peeling off the adhesive paper and peeling of the leather,
1128190	1136450	it's not that easy, but you get the picture. If you do receive a do-it-yourself or DIY badge,
1137350	1144330	it's going to be quite obvious where the parts go, right? There is a user manual,
1144330	1153330	but I'm hoping people aren't too confused about that. So this is where we're at now.
1155430	1159050	What we can do next is take a look at...
1162130	1167710	Oh, I kind of missed a couple things. So we're going to backtrack just a bit, shall we?
1168270	1175690	So this is kind of what the pieces of plastic look like. This one, I got it wrong. So it's
1175690	1180310	broken up here. It stopped working correctly. This is the green. And you can kind of see
1180310	1187790	that it's translucent. So if you do a DIY attempt and you make your own plastic
1188970	1194370	enclosure frame, you have a wide variety of choices. You can do clear plastic. This is
1194370	1201150	why the ultraviolet cured method is so nice. Anyway, so I thought that might be worth
1201150	1208070	demonstrating. This is approximately 20 frames, but the job stopped too early. So you can see
1208070	1215350	that it's a bit messed up. And that's where the ICs come out of, tapes like this, right?
1215350	1220070	So this is for those of you who are maybe a bit curious. I can't even get close enough,
1220070	1222990	probably, to show you these parts. They are so small.
1225110	1232670	And these are integrated circuits. So in an advanced badge clinic,
1233430	1238690	I won't promise anything, but I do have a microscope. And I'm going to try to get a bit
1238690	1246610	more wild and crazy with the OBS open source. What is it? Open Broadcasting System. I'm a big
1246610	1253010	dummy with video. So if I get it right, then we can look at these integrated circuits under a
1253010	1261350	microscope. But this is actually what is placed in these positions. One, two, three.
1261350	1269070	Okay. So that's the construction. And here are the switches. If you can see
1269070	1275610	that there are some switches on there. These are dome switches. This is not very typical.
1275610	1281090	These dome switches are nearly never used. And you need a front overlay if you're going to...
1281690	1290690	see how that's embossed there? And it makes a clicking sound when you click on there. That's
1290690	1296410	because it's tactile. So it's a tactile switch. And it's embossed. And that's what the switches
1296410	1303710	look like. They're called dome switches. Right. So... okay. I'm never going to get those out of
1303710	1314790	it. Keep this place clean is what they always say at the lab. Here's a sample of the liquid plastic.
1314990	1321150	So I'm not even going to open this up because it stinks quite bad. And it's photosensitive. It's
1321150	1330450	the photo emulsion. So that's kind of how these badges are made. There's the frame. Okay. So
1332270	1340530	once in a while, I'm just going to take a look on Discord because if you have questions in between...
1342750	1347510	I'm not sure if I can do this Discord and OBS at the same time. Does that work?
1347650	1357720	Justin, does that work? Answer me. Yeah. Okay. So let's see. I'm starting Discord now. And I will
1357720	1363520	try to respond to questions because as we go, some of these things are extra interesting or
1363520	1369040	extra confusing or you made one just like that, but you have this question. So I'm going to try
1369040	1376340	to maybe field a few questions as we go. When we leave it towards the end and we're talking a whole
1376340	1385680	hour, then you may forget the question. That would not be good. Here, check this one out. This is
1385680	1392300	another frame. This is a kind of a... it's not white, but it's not clear either. What do you call
1392300	1402780	that? Milk color or ice? I have no idea. Anyway, so that's kind of nice. And the advantage for all
1402780	1410340	of you who maybe are experienced with fused deposition modeling style 3D printing, that's
1410340	1420600	where you have hard plastic and you melt it into a new shape. The big advantage, in my opinion,
1420600	1426860	to this liquid photo emulsion is that you can actually mix them. You take a bottle like this
1427540	1434460	and you mix it with a blue and you mix the blue with a red, you end up with purple.
1434460	1440400	Right? So that's pretty nice. And then you pour in some transparent, and so it makes the purple
1440400	1445580	that was solid, it's translucent now. So yeah, those are some tips if you're going to make your
1445580	1452620	own frame. You can do that and you can maybe... it depends on the printers. The SLA, the
1454800	1458540	stereolithographic printers are a lot more expensive than the FDM, the fused deposition
1458540	1463480	modeling printers. You can use either one. You may have to adjust the model just a bit
1463990	1469320	if you use FDM because the technique is a bit different. So the overhangs, well, it's not
1469320	1474300	important. We'll maybe get to that if there is a question and I'll make a drawing here on the paper.
1475660	1479580	All right. So what we were going to do
1483090	1495220	was move to the package contents. Shall we? Shall we do that? Can I find a package?
1497200	1502800	Probably not. Yes, I found one. All right.
1506600	1508940	So there's a package.
1510160	1516500	They're going to always be black like this, so don't send back black packages. It's not the
1516500	1523800	Mafia. It's Monero Devices. Sends you a black package in the mail just for extra hackiness.
1523800	1529240	All right. So that's the only thing that's in there. So you get a pretty spiffy
1530840	1538480	box this time. We had some problems last year with the... do you remember those?
1538600	1546000	We had some problems with those. On the side there, these connectors were getting bent
1546600	1551120	because we didn't have proper packaging. How can I focus on that?
1552160	1561080	I don't want my fingerprint in there. No, it's not focusing, guys. But you get the idea. There is a
1561080	1564540	metal piece on the side, and those were getting bent. I think some of us
1564540	1570980	had to bend them back in shape. So we didn't have very good boxes last year,
1570980	1575580	and we learned our lesson. That's kind of what this is about. We're always doing experiments,
1575580	1579760	trying new things, and then about half of them work, and the other half, well, they don't.
1580320	1584800	All right. So this is the box. It has a label on the side so we know what it is,
1584800	1591000	because there is black, there's orange, red for the red team, blue, blue team, you know,
1591000	1600760	green for Matrix Green and biohacking, and orange for Monero. So that's the back of the box. We have
1601080	1607600	a great UPC code from our friends at Hack5, who is one of the premier shops as well as Cypher Market
1607600	1614440	that are carrying this. We decided to test and experiment a bit with holographic seals
1615040	1620060	on the side. I'm not sure who's doing this. I think there are a few other manufacturers of
1620060	1625440	secure hardware that do this. I don't think... I mean, I'm going to keep... we're going to keep
1625440	1635380	putting holograms on there, but not for security. Okay. I mean, think about it. If you have a
1635380	1641700	hairdryer, you probably can get these holograms off quite easily. What do you do then? You open
1641700	1648960	the package, you manipulate the thing, right? You program new identifiers on there or some
1648960	1654660	other sloppy thing, anything you like, real dirty stuff. Then you put the device back in the package.
1655520	1660860	You're very careful with the seals that you removed. I mean, I haven't tested this too much.
1660860	1666880	I was hoping that the intrusion detection team, there's an actual village. I'm sorry, not team,
1666880	1670760	it's a village. I was hoping that intrusion detection would be on board with the intervillage,
1670760	1677280	that they would be one of the, whatever, five or 10 villages. But the intrusion detection village
1677280	1684140	is not active or participating this year. This is like a few others. Sky team, Skytox, I'm sorry,
1684140	1690680	Skytox is not participating. There are a few villages like that. So we got unlucky with
1690680	1696340	that. And we just have to wait until we get a report from them, if this is good for any reason
1696340	1705600	at all. The one thing that is very, very good about this, if we can get a focus, is that it is
1705600	1716660	quite attractive. Do any of you see the symbol, which is inside the holographic 3D?
1717980	1725840	You probably do. You're just all raising your hands and I can't see you. All right. So that's
1725840	1731860	kind of a very, very, very cool appearance, right? That's one of the reasons we will keep using
1731860	1740420	these. And maybe if we get lucky, we kind of learn how to use them, how to apply them in a manner.
1740420	1750180	The truth is, if you remove this, it will leave a, what do they call it, self-destructive
1751300	1757080	message behind. It says void. You can't choose too many. Void is one of them. So
1757080	1762220	if you peel that off, I won't demonstrate now, but if you peel it off, it is pretty easy to
1762220	1767720	see that there was a seal there and now there's not anymore. And if you put a new seal on,
1768280	1775220	then it covers up the void marking. But if you look at it closely, there's something wrong with
1775220	1782760	it. You can tell. So that's kind of, if we get far enough into examining this intrusion detection
1782760	1790360	holographic seal system, we may get lucky enough to make it useful for us. It probably will at least
1790360	1800000	solve the very low hanging fruit problem where a person would just go into the box,
1800000	1804280	replace the badge with one that they have in their pocket because theirs is broken and yours
1804280	1810500	is not. So this is kind of a low hanging fruit intrusion protection slash detection. We've got
1810500	1816980	the shrink wrap to make it, you know, set up, put another five minutes of time for an attacker.
1816980	1823720	We've got the holographic seals and the only, there's not a good reason for this. I mean,
1823720	1832080	we do pre-program these three EEPROMs with data out of the factory and they're random data. So
1832080	1840360	we don't store them, which means it's impossible to track or obtain, you know, any organization,
1840360	1847860	institute, agency. It would be impossible to capture the database of all of these factory
1847860	1854100	programmed identifiers because we don't store them, right? It makes no sense. We're just
1854100	1859940	writing random data to each one. But if there were a meaning, if we had some reason
1861280	1868440	to ensure that they're unique or something like that, to use them for signing documents,
1868440	1876120	you know, like a public address or something like that, then these holographic seals may
1876120	1881080	help a bit. They would at least protect and defend against the low hanging fruit attacks where
1881080	1885120	without the shrink wrap, without the holographic seal, it would just be another
1885640	1892540	15 minutes faster to make that replacement and intrusion. All right. So that's just what I wanted
1892540	1898420	to show is kind of a generic thing that we can reuse maybe for the next couple of months or a
1898420	1905640	it's really laborious, time consuming and boring to design, make, and communicate with gift box
1905640	1910820	manufacturers. So I don't want to ever do that again. And so we're going to have quite a few
1910820	1917960	runs at this generic packaging, and this will be the first one. All right. So let's open one
1917960	1925460	of these boxes up. That's how it is when we have the shrink wrap off. I'm always using this to
1925460	1935660	open it up. It's a poor man's wrench, I guess. Come on, open. All right. So there we have a
1935660	1944040	do-it-yourself model. I can tell because the do-it-yourself model has the black and white,
1944040	1954180	cheap printed on a laser printer manual, whereas the more elegant model, that's the one that comes
1954180	1963360	with the colorful frame, that comes with a color manual. And so the reason I want to show this is
1963360	1969300	because I personally think this manual is the nicest part of the entire package. All right.
1969300	1977000	If you're excited about holographic seals and photo emulsion, stereolithography and all that stuff,
1977000	1982840	no, you got it wrong. This is definitely the nicest manual I've ever seen in my life.
1983440	1989500	So the printers got it right. They put it on just the right gloss. They got the colors very good.
1990700	1996880	But the main reason this thing looks beautiful is that we got lucky and a very talented
1996880	2004800	illustrator and graphic designer contributed the design. I don't know if I'm allowed to say who it
2004800	2017860	is. Can anybody guess? Revar, what do you think? Who is this? Really? No, that's not... yeah, that's him.
2017880	2025180	All right, Revar. Revar got it right. Okay. So anyway, so this is the manual.
2025360	2031280	We've got a quick start there. It's rather clear. It has a couple models. Their hands are on there.
2033020	2036060	Lots of big writing. There's a bill of materials.
2037260	2041720	There are a few people that participated and then it's double-sided.
2043120	2048960	Yeah, I really like this. There is some code there. There's just enough.
2048960	2054700	You know, this is not like a 60, a 50, 60 page manual. It's not stapled in the middle to make
2054700	2061960	it read like a book. But you get the idea. I mean, this manual is just very, very nice.
2062860	2069560	I don't know why. I mean, I'm just saying that my opinion is that it's very nice and that I wish
2071640	2079580	that the illustrator and graphic designer would talk to us about it and to come on and explain
2079580	2085200	his methods, his techniques, everything she or he does is open source. And so, I mean,
2085200	2092160	the person is just wonderful. Anyway, so there's reasons which are not so interesting why we have
2092320	2099780	a color manual and a black and white one. We had to do a second one because we got the idea to do
2099940	2105660	a do-it-yourself model a bit late. And then we didn't want to have the frame on here,
2105660	2108920	which was confusing. The do-it-yourself model doesn't come with a frame.
2110900	2116040	That's what it comes with, but we'll get to that in a bit. And so, we needed kind of a different,
2116940	2120200	basically a different manual. So, this tells you how to put it together,
2120580	2127180	which really only makes sense if you have a parts kit, like a do-it-yourself parts kit.
2127960	2132540	Right? So, this is kind of similar, but it's just not as beautiful, not the printing,
2132540	2137860	you know, glossy paper, not as large. But you do get a manual either way,
2138640	2146700	which I think is kind of important anyway. So, that's how we got to the inside of this
2146700	2151140	do-it-yourself kit, right? So, this is the do-it-yourself, the less expensive one,
2151140	2155760	the one that I actually recommend to all the hardware hackers, because let me tell you,
2155760	2162440	after you remove all of this foam and stuff, what you end up with is the raw PCB like this. I mean,
2162440	2169280	it does have assembled switches and ICs. But what I'm saying is that instead of
2170080	2175720	an already placed piece of leather here, which blocks the circuits,
2176360	2184400	what you end up with, if you receive a do-it-yourself model, is the surfaces which
2184400	2190180	you can solder on. You can inspect them, you can attach probes, you can put a multimeter,
2190180	2200020	an oscilloscope on there, and you don't have to rip the leather off. It's a bit unfortunate,
2200020	2207240	let me say, not really disingenuous, but unfortunate that when you put the leather on,
2207240	2214380	that's this stuff over here. When you put the leather on the back, the adhesive is so strong
2214380	2220120	that it's kind of difficult to get it off. So then you have the problem, if you want a lanyard
2220120	2225660	on there, are you going to drill through the leather? There's all this stuff that is easier
2225660	2233520	to do before you assemble it. So that's the reason that you may like a do-it-yourself model
2233520	2242440	instead of the fully assembled, fully luxurious, the most elegant one with the made-for-you color
2242440	2249040	translucent SLA photo emulsion frame, all that stuff, right? And the color manual. I mean,
2249040	2252800	I don't know, I'm just trying to give people a choice. I think choices are good. So you can
2255020	2262740	do what you want. Anyway, this is what comes in the do-it-yourself model. You take this out
2264000	2274410	and then you receive three components. It's quite obvious that the
2276210	2282470	assembled PCB is there. We didn't want to send these out unassembled to the do-it-yourselfers
2282470	2289290	because, and it's not going to, I don't think it will focus, but because the integrated circuits
2289290	2300070	are so small that it's really difficult. Let me just show you in comparison. I do have somewhere,
2301370	2310040	here they are. So I do have somewhere some standard size parts.
2311640	2320300	And so we can, for a quick comparison, we can show, great, I lost it. All right, here it is.
2320300	2327180	So we can show the size of a normal part, the SMT surface mounted technology part.
2329460	2337380	And if you look beneath them, that's where the ICs are for the intervillage batch.
2337380	2342980	That's how big they are. And what that tells you is that if these PCBs, printed circuit boards,
2342980	2348920	really did arrive in your mailbox as a do-it-yourself parts kit, and you had to solder
2349440	2355360	these integrated circuits onto the board, you just might go crazy. I mean, you definitely would
2355360	2359140	abandon the project, give up, and you would not have a working badge.
2359140	2363580	That's why we have shipped even the do-it-yourself
2366140	2373700	models in a partially assembled state. These switches are a bit difficult to get on there
2373700	2378200	as well. And the manual pages, which would be required to explain how to do this
2378200	2382660	and get it centered just right, and how to understand that the circuit is not
2382660	2387140	shorted or anything, would be another 10 pages. It just makes everything sloppy,
2387140	2391140	difficult, unappealing, and yeah, we don't need that.
2393420	2402460	Right, so now you know what components you receive in the bag when you receive a
2403180	2410040	kit of parts. That's these here. This is the deconstruction or the before you build and
2410040	2416040	construct your DIY model. And I think it's clear enough already, because we've talked about it,
2416040	2422700	that the membrane overlay or the front cover, this goes on here, right? You have to peel off
2423200	2428520	the back. It's kind of like a sticker. So you peel that off, put that on there,
2428520	2435440	it's going to be all crooked, right? I mean, I may give some tips later on. It's, you know,
2435440	2441580	if you get it crooked, you can readjust it. It's quite easy to do that. So, and then you turn it
2441580	2449240	over. And that's the leather. You take the peel off of the leather, the adhesive peel, and then
2449240	2457420	put it on there. And after you do that, you end up with almost the same thing.
2458760	2468340	God, this place is a mess. Would one of the village people please come over here and clean this up?
2468900	2474600	Because it's really difficult to give a presentation at the same time as... So I do
2474600	2481040	need an assistant to come over to this table and clean up my just load of crap here. All right. So
2481040	2485580	that was a joke in case you don't know, there's nobody else in this room, right? I keep saying,
2485580	2494760	please raise your hands. All right. Nice jokes. Okay. So this is the pre-assembled, no,
2494760	2499180	not pre-assembled, what do you call that? The unassembled, the not yet pre-assembled
2500380	2506780	kit of parts for the do-it-yourself. And after you put the front overlay on and the back leather,
2506780	2513640	then it ends up like this. You cannot choose a color for the DIY. We're just considering, okay,
2513640	2518220	people can choose five colors for the pre-assembled, five for the do-it-yourself,
2518220	2523340	then they can choose what, if they get a frame as well, you know, no, we don't want more than
2523340	2530620	like a half dozen choices. This starts to get too difficult to service, right? So once you,
2530620	2534560	if you do choose a DIY, it seems that they were quite popular. Most people want these
2535060	2539680	because I don't know why, but it's more fun to put it together yourself, right? There's a few
2539680	2546160	disadvantages like, well, whatever, but you get that, then it turns into this after you're finished
2546860	2554160	building it yourself. You'll have to print your own 3D frame at the hackerspace. And then you put
2554160	2561900	that on and that completes your device. All right. If you like the idea of receiving a color manual,
2561900	2566960	I mean, anybody can do that as a beauty of open source. You can even have a color manual
2568340	2573420	for free because you can download it, right? It's just a matter of if you print it,
2573420	2579940	it's not going to be this size pre-folded by folding machines, perfectly 90 degree angles
2580620	2587340	with no bleed to the edge printing and glossy ink, right? It's just, but you don't need that
2587340	2594180	anyway. What do you need? You need a file download, which you can find on our shop.
2594180	2601360	That's where you purchase, you receive a device, but you can download the free of charge user
2601360	2608700	manuals as well. The black and white one, the color one, you get all that stuff. I mean,
2608700	2613980	there's not a whole bunch of files to download there. What it's really meant for, the shop.monero
2613980	2621400	devices.com, it's really meant for distribution, for helping us replace this physical model where
2621400	2627400	people without masks are walking next to each other and saying, hi, I want a badge. And then we
2627400	2636100	say, okay, there you go. Put it in your hands, right? We have to replace that pre-pandemic model
2636100	2643640	with a virtual, what distributed nobody in the same room model. And that's why we created the
2643640	2651280	shop, the factory shop called shop.monerodevices.com. That's where you can download manuals,
2651280	2658480	but it's not made, it is made to replace the personal meeting in a room, pick up your
2658480	2667440	hardware device system. What it's not made for is to replace the public repository where all of the
2667440	2675580	design files, the archives and other things are found. Like for example, the source code
2675580	2683820	for the manual is there. The PDF itself, the finished proof and copy is on the shop,
2683820	2688940	as you might expect. And the source code for this is in the repository.
2690200	2696200	Yeah, I'm not very well equipped, organized to start opening screen scraped and
2698780	2706080	websites. Let's do that tomorrow, shall we? But, and we'll continue on just inspecting the
2706080	2713400	components right now. But there is the S, it's called SCM. I'll write that down.
2720260	2725700	So a couple URLs to remember. We've already covered the shop.
2731860	2738560	That's for distribution. Like we always do in the village physically, we are now doing online.
2739300	2743660	There. And then we have SCM.
2745340	2748220	Then we have the SCM, which stands for
2753560	2764260	source code management. Do you like the way I did that sideways?
2765300	2773240	Does that help you if you're side to side, can't deal with it? All right, so you get the idea.
2773240	2784520	This is Monero devices. All right, and the SCM, the source code management system,
2784520	2789740	that's where you get the raw sources. What else should I call it? So you,
2789740	2795900	I don't think you can receive the PDF version of the manual there, but you can receive the SVGs
2795900	2802580	there, the scaled vector graphics, right? And then it's a bit difficult to construct a PDF
2802580	2807880	from the scaled vector graphics because of fonts and things like that and lines.
2808440	2814540	But if you want the PDF, you get it there. All right, so where are we and how much time do we
2814540	2822340	have? I'm going to just take a look, see if we're doing okay. Now, what I'm doing right now is
2822340	2835460	I'm going to our Discord DefCon channel. It's the village. Just like we have SCM and shop.monerodevices.com,
2835460	2842260	we have this year no room at Valley's and no room at Paris or anywhere else, Flamingo.
2842260	2849860	Instead, we have a chat room, a series of chat rooms on the Discord server. So if you're just
2849860	2857540	watching this online in video, you're not sure how to get involved in DefCon in general or
2857540	2869760	walk in our village if you want to do that, then the way to do it is with the Discord server.
2870780	2879840	All right, so just let me get to our room so I can try to see. God, there's a lot of channels.
2881560	2889180	So there's a lot of content, even though it's virtual this year. And probably the next thing
2889180	2895440	we will do is take questions and answers because we've covered all of the components
2896040	2902480	that go into building a badge. And that's what we wanted to focus on
2904540	2910280	in this hour. I'm just scrolling, scrolling, scrolling. There's the crypto village,
2910280	2916820	the ethics village, and we're coming up soon. Ham and radio village. What's wrong with these
2916820	2923500	people? Why aren't they part of the inner village? Oh, here is a hardware hacking. ICS.
2923500	2931500	My goodness. IOT lock bypass. Lock picking. Here we are. Okay, Monero village.
2931680	2939500	All right. So I don't see any questions yet. I'm sure that you're thoroughly bored. But
2941560	2949500	I also don't have much more to say about the components that make up these badges.
2949500	2960220	So it's time to either close early or ask for questions. And if anybody would please...
2962000	2967820	Right. If you have a question... I actually don't know how this works. I assume
2967820	2976200	that a moderator will... How does this work? If you're not on Discord and you're on IRC or
2976200	2981340	something, somebody translate, put it on Discord. Otherwise, we're going to finish
2982960	2988740	a few minutes early. So let me see what we're doing here.
2992040	2999720	Yeah, the general channel is no questions. Off topic channel.
3000460	3007080	No questions. And the office channel for office hours, I see no questions at all.
3007900	3016500	Okay, so we're going to finish early. It's the last chance to ask your question.
3017060	3030780	And nothing there. So please come back for the next presentation, which I can just find it.
3036290	3044950	By the way, you cannot download these slides. Okay? You can't download them. Sorry about that.
3045670	3051870	Because they're paper. Do you get it? All right. These slides are paper. Don't download them.
