00:00:00.834,00:00:02.836 [background music playing] >>Well goodmorning everybody. How's everybody doing?[light 00:00:02.836,00:00:07.808 applause and cheer] Good? [cheers] Aright. How many people drink coffee? How many people 00:00:07.808,00:00:12.813 like good coffee? Well, if you like good coffee, you're gonna learn what you can do with that 00:00:15.215,00:00:21.021 Keurig during this uhh during this talk because Keurigs uhh produce mostly garbage but 00:00:21.021,00:00:26.026 really cool stuff. So let's uhh let's give Evan a big round of applause. [crowd applauds] 00:00:32.065,00:00:37.070 [music changes] >>Thank you. Everybody hear me alright? Sound good? Awesome I'm Evan umm as as 00:00:40.340,00:00:44.478 the gentlemen said. Uhh we're gonna start off today uhh with my uhh shotgun of random. I need 00:00:44.478,00:00:48.148 to put a a few rounds through real quick. [shotgun cocks over video] Just to get us going 00:00:48.148,00:00:50.918 [shotgun fires] So a lot of these guys around these protocols they're gonna become 00:00:50.918,00:00:55.355 more popular. Um uh uh companies like this are going to start adopt adopting them and then 00:00:55.355,00:00:59.726 they're gonna get cheaper and cheaper, cheaper and cheaper and then eventually it's going to be 00:00:59.726,00:01:03.130 in uh new construction and then everyone will have this connected home thing, right? And 00:01:03.130,00:01:08.302 so um eventually uh the audio will be connected, uh lights in your home will be connected, and 00:01:08.302,00:01:12.572 then someone's gonna find a a God awful exploit and then ah I really hope that it's one of you 00:01:12.572,00:01:17.577 and you have a sense of humor and one of you uh does this. [Video begins] [gunshot sound] 00:01:22.516,00:01:28.422 [gunshot sounds] [gunshot sound][gunshot sounds][gunshot sound] It's murder night! Yeah! 00:01:28.422,00:01:33.427 Wooo! And also this, umm [coughs] Alright. [audience murmurs] [shotgun cocks] Cool 00:01:42.169,00:01:47.841 [shotgun fires] So the next time that you tell a joke that's uhhh that everyone in your in your 00:01:47.841,00:01:52.045 aud in your crowd should get and then umm they're a jerk about it and they don't get it, er I 00:01:52.045,00:01:56.083 don't know say this, say "Hey look man, I'm sorry, it it was an inside joke, this thing we 00:01:56.083,00:02:01.254 all had to learn in elementary school like you really, you just had to be there I guess." So. 00:02:01.254,00:02:06.259 [shotgun cocks] Alright. [Video begins, outdoor noises] >>Fwha? Is that a goat? I just redid my 00:02:11.932,00:02:15.168 deck [goat noise]. >>I have a deck goat. [clears throat] Officially. [shotgun cocks] This 00:02:15.168,00:02:19.806 is all random stuff. [shotgun fires] Cool. Wouldn't it be terrible if you had some 00:02:19.806,00:02:24.177 condition where like all of your inner dialogue was in garden path sentences? So you'd be like 00:02:24.177,00:02:30.117 "Did I leave the bathroom light on... toilet... paper? Dangit." Great [shotgun cocks] Google 00:02:30.117,00:02:34.021 that later. Okay well [shotgun fires] those guys who were jerks that were like who says like 00:02:34.021,00:02:37.124 someone walks by quickly and they're like "Hey where's the fire?" Like that is the one time 00:02:37.124,00:02:41.428 that I really wish that I could produce fire out of my hands. That would be the best time for 00:02:41.428,00:02:47.300 that. [shotgun cocks] Alright. [shotgun fires] Is Deviant in here? Deviant? [silence] Cool 00:02:47.300,00:02:51.905 watch it later. Okay so umm yeah so Deviants a uh we were all sitting around at CarolinaCon 00:02:51.905,00:02:56.743 having a conversation, umm, and he got paid a compliment by uh Shaf and uh just wanted to let 00:02:56.743,00:03:00.113 you know that Shaf was absolutely right about that one hundred percent. And while we're 00:03:00.113,00:03:06.286 here umm anyone like yard sale in here? Anyone like yard salers? Anybody? Someone needs 00:03:06.286,00:03:09.423 to make an app because sometimes you find stuff that's still like in the package you know? Someone 00:03:09.423,00:03:12.659 needs to find an app that you can just like scan that and uh it'll tell you where to return 00:03:12.659,00:03:18.698 it and how much you can get for it right? [chuckles] hmmm. [shotgun cocks] Cool [shotgun 00:03:18.698,00:03:23.336 fires] ooop [shotgun cocks] Alright well ok cool. Okay so this is Jittery Macgyver. That 00:03:23.336,00:03:26.807 was a shotgun of random, sorry. Umm we're today we're going to be talking about finding 00:03:26.807,00:03:31.745 potential, and uh I guess another way of looking at this is uh is "Macgyvering" right? So 00:03:31.745,00:03:36.216 who watched Macgyver growing up, in here? Should be a lot of you right? So if you if you're the 00:03:36.216,00:03:40.487 uninitiated Mac- Macgyver you could uhh you could put him in any situation give him any any 00:03:40.487,00:03:44.825 stuff right and he can like use that stuff and and like find a solution and get his you know 00:03:44.825,00:03:50.030 get him in back in to safety, right? So umm really cool guy, a lotta fun to watch, uh and I I'm 00:03:50.030,00:03:54.134 I really love that that kind of problem solving that kind of engineering. So umm let's look 00:03:54.134,00:03:59.072 at a couple examples of of like solid Macgyvering throughout history. Ready? So um the first 00:03:59.072,00:04:05.378 one is George Washington Carver. Uh this guy is is a complete and utter badass. So um he uh he 00:04:05.378,00:04:10.450 arrived actually at a at a new job, he's like the director of ag- agriculture at uh um uh some 00:04:10.450,00:04:15.055 college in Georgia right? And uh they didn't have money to buy his lab equipment didn't even 00:04:15.055,00:04:19.259 tell him about it right? And so like instead of like you know rage quitting he uh he took his 00:04:19.259,00:04:23.697 students and he like he, they went and scavenged like junkyards and stuff and found 00:04:23.697,00:04:26.766 lab equipment and like eventually got all the stuff they needed to you know make 00:04:26.766,00:04:31.338 cool stuff happen. And you guys probably know umm uh Mr. Carver for his work on the peanut 00:04:31.338,00:04:35.041 right, he made you know a couple of things with that. So he looked at that and he said "You 00:04:35.041,00:04:38.612 know there's there's some potential here in this little thing." And uh he did a whole 00:04:38.612,00:04:44.851 whole lot with it. Another really cool example is um uh uh Cuba. Right so like in in '91 uh 00:04:44.851,00:04:50.290 when the um uh Soviet Union dissolves they uh uh Cuba found themselves in a in a really bad 00:04:50.290,00:04:54.327 financial crisis, right? Uhh they couldn't like trade with anybody and so they they sorta 00:04:54.327,00:04:59.166 had this stuff and they had to really make do with what they had. Uh just to just to get by. 00:04:59.166,00:05:03.170 So I mean the the whole whole place turned into a bunch of Macgyvers right? And the 00:05:03.170,00:05:06.006 government knew that it'd take them a long time to like work work their way out of this 00:05:06.006,00:05:10.076 problem, so they put out these two publications. One was "The Book for the Family" and the 00:05:10.076,00:05:14.481 other is uh uh "With Our Own Efforts." And basically these are like giant compilations of 00:05:14.481,00:05:19.519 like popular mechanics, and like recipes, and how to guides and just using stuff that they 00:05:19.519,00:05:24.191 already had right? So this this book is really interesting, it's uh it's pretty long it's like 00:05:24.191,00:05:28.028 three hundred pages long. Uhh I'll highlight some some of the the really interesting things 00:05:28.028,00:05:34.134 for you here. So um, I've first off is uh is this cutout of the person with like a a an 00:05:34.134,00:05:38.772 uncomfortable amount of attention paid to the nipular region,for [audience 00:05:38.772,00:05:43.043 chuckles]God knows why. Umm. This is uh it looks like plans for a for a primitive kill 00:05:43.043,00:05:48.748 yourself device hhh.[audience chuckles] And if you like the AK-47 you're gonna love AK-47 on 00:05:48.748,00:05:53.553 a stick for...[audience laughs] reasons [more laughter] This one's my favorite though this is 00:05:53.553,00:05:58.758 the the "Desplasmatizador" and uh this you take jars and you connect them with either wires 00:05:58.758,00:06:04.497 or tubes or something maybe some needles, this is uhh I think that's uh maybe like uh like 00:06:04.497,00:06:09.603 unsettled uh uh Italian dressing or something? I don't know. But anyways you you plug all that 00:06:09.603,00:06:14.140 into what looks like uh either a motor or a or a uh compressor from a refrigerator and then you 00:06:14.140,00:06:18.144 plug that immediately into the wall. And I think this probably opens up a a portal to a to an 00:06:18.144,00:06:23.083 alternate dimension where terrible ideas come from. But uhh One thing that everyone had 00:06:23.083,00:06:28.555 is is this Aurika washer slash dryer combination. And everybody's dryer, part of this 00:06:28.555,00:06:32.659 thing, cracked out, right? Something went wrong with it, and couldn't use it anymore, so 00:06:32.659,00:06:36.863 like this this spawned a whole like underground industry of people who were crafty enough to 00:06:36.863,00:06:41.234 take these things and like most of the time they would just cut it right in the middle and 00:06:41.234,00:06:46.106 discard the uh the dryer part. But the motors in them were still good. So they used those 00:06:46.106,00:06:50.910 motors for everything. Like this is shredding coconut, this is a key duplication machine, um this 00:06:50.910,00:06:56.349 I mean it's like a outboard motor ep em empeller er propellor and um slapped it on 00:06:56.349,00:07:00.887 the motor and made a fan, right? Pretty awesome. And everything was like this. So umm if you 00:07:00.887,00:07:05.025 wanted something you had to build it. And so you had like glasses like these, which would 00:07:05.025,00:07:09.596 like earn you plus ten charisma for even looking at them I think. [audience laughs] Holy 00:07:09.596,00:07:14.301 crap [audience laughs] And like these locks are look they look pretty secure, right? I dunno. 00:07:14.301,00:07:19.706 Uh yeah maybe those are they have some in the lock pickers I dunno. Uh this thing, uh 00:07:19.706,00:07:24.978 supposedly this this uh like refreshed uh hearing aid batteries. Umm also if you if 00:07:24.978,00:07:29.115 you were drinking while you used it it would remove the need for hearing aids all together 'cause 00:07:29.115,00:07:34.287 you would be dead a lot. [audience laughs] So um this is actually like [chuckles] like 00:07:34.287,00:07:39.125 homemade plastic extrusions stuff, right? So like if if OG like Cuban Baine was around he'd 00:07:39.125,00:07:44.364 be like "Ugh you merely adopted 3D printing erherher." Right? And everything's like this. So 00:07:44.364,00:07:50.036 they use these metal food trays as a as antennas. It's amazing stuff so uh a lot of really 00:07:50.036,00:07:53.173 really interesting stuff. There's I guess a whole website uh it's called Technological 00:07:53.173,00:07:58.778 Disobedience uhh just like dedicated just for this stuff, right? So another er really 00:07:58.778,00:08:04.718 great example it comes from 1970 and uh April 11th we launched Apollo thirteen. And you guys 00:08:04.718,00:08:08.288 know that you know we got into space okay there were a few hiccups here and there and we 00:08:08.288,00:08:13.126 were you know trucking along and all of a sudden [Voice over video] ...Houston we have a 00:08:13.126,00:08:17.931 problem here. >>This is Houston say again please. >> Uh Houston we've got a problem. Now Houston 00:08:17.931,00:08:21.768 we've got a problem. Right so they got uh uh they thought they got hit by hit by an asteroid at 00:08:21.768,00:08:25.839 first but turns out it was just uh just a short in some some Teflon insulation on some wires. 00:08:25.839,00:08:30.710 Tt caused a fire it caused an oxygen tank to explode and then all of the sudden like they 00:08:30.710,00:08:35.515 don't have any life support. So they had to tunnel over to the lunar module and stay over there 00:08:35.515,00:08:39.919 'cause that had a separate life support module but uh the problem was that they uh were 00:08:39.919,00:08:44.991 clogging the the lithium hydroxide filters which scrub the you know the the air um from 00:08:44.991,00:08:48.728 you know for the like the of C2 and it it makes it breathable again right? So you've got all 00:08:48.728,00:08:51.898 of the astronauts uh in this thing and they need to be in there for four days, that's way 00:08:51.898,00:08:57.404 too long. So NASA they they you know anticipated this and uh they got busy right? So they're 00:08:57.404,00:09:01.875 back at home base and like "well they've got filters but you know they're they're square and they 00:09:01.875,00:09:06.546 need to fit in a round hole" and that's like the literally the the the peg scenario, right? So 00:09:06.546,00:09:10.750 they came up with this. This is the mailbox rig. Basically they just took like, you know, the 00:09:10.750,00:09:15.355 the cardboard cover off the flight plan and a piece of you know plastic here and a tube 00:09:15.355,00:09:19.159 there and all this stuff, and they they you know made it back on Earth and then they sent them 00:09:19.159,00:09:22.128 the instructions. And they're astronauts so they figured it out you know and they made one 00:09:22.128,00:09:27.133 themselves. Look how calm he looks, just like "Yeah, I just made a mailbox rig." [audience 00:09:27.133,00:09:30.970 chuckles] Saved, uh, everybody's life right? So you guys probably know this story, but my favorite 00:09:30.970,00:09:35.442 part is this guy, Ed Smylie. He's the uh the was the chief of pre-systems division at the time 00:09:35.442,00:09:40.447 and he spearheaded the design and the the testing of the mailbox rig and uh he's amazing. 00:09:40.447,00:09:43.850 And something that he said later, like after they landed, was this: "So when I found out 00:09:43.850,00:09:48.855 we had duct tape on board, we were pretty well homefree." [audience laughs and claps] 00:09:55.128,00:10:00.800 Crazy. So those are a few great examples in history that I love. Umm wanna talk about the few 00:10:00.800,00:10:04.471 things that I've done personally, right? So um, the first thing is everyone's got 00:10:04.471,00:10:08.808 like a Big Ben of of cables in your in your home in your office, in your closet, 00:10:08.808,00:10:13.413 somewhere right? I I was no exception and I I you know found that thing and I was like "You 00:10:13.413,00:10:17.717 know I ki- I wanna do something with this." So I made a universal serial bullwhip. And 00:10:17.717,00:10:22.622 this is uh uh uh eight foot, uh eighteen blunt bullwhip [audience stirs and murmurs] And 00:10:22.622,00:10:28.495 there's a uh a very thin leather belt on the end with a regular nylon cracker and um there's one 00:10:28.495,00:10:35.435 thick like DVI cable like as the trunk in the middle you know. And uhh you think it cracks? You 00:10:35.435,00:10:40.907 wanna see? [Video plays] [Video freezes] Uh well, tell you what, hang on. I've got it right here. 00:10:40.907,00:10:45.912 Let's do this thing live, alright? [audience claps] So this is probably the first time 00:10:49.849,00:10:54.854 ever that uh you guys need to pray to the demo gods huh? [audience laughs] [strong whip 00:11:07.400,00:11:13.072 crack] [audience claps] That's a bunch of metal. It'd probably tear your face off. Alright. So 00:11:13.072,00:11:17.210 another one I was going down to a conference in Atlanta and I I brought this giant uh pelican 00:11:17.210,00:11:23.116 case just full of office stuff, right? So I immediately got to the hotel room and don't tell 00:11:23.116,00:11:29.455 them that I uhh well...I took everything apart and from the ashes arose Milton! And Milton, 00:11:29.455,00:11:34.060 I don't even know what it is, exactly, but it's like a a really heavy spiky bat thing 00:11:34.060,00:11:39.699 with a with a red swing line on the end. Um...for the name [audience laughs] Dude, paper 00:11:39.699,00:11:44.337 shredder heads are are like they're gnarly man like good grief [audience laughs] I got so 00:11:44.337,00:11:48.341 many like little pricks and cuts and that's RJ45 just wrapping everything everything together 00:11:48.341,00:11:52.645 like a boss. So basically just took uh, like you guys ever heard of like an all in one 00:11:52.645,00:11:57.116 printer? It's like gears and rods and like demons hah it's like I don't even know how it 00:11:57.116,00:12:01.921 works man. There's there's a spell on all of them. And I took like the long you know sturdy 00:12:01.921,00:12:06.559 pieces and then I wrapped them all in like some uh uh like case metal right? And I duct taped 00:12:06.559,00:12:11.564 all that. And this is the size of it. Umm. Compared to uh, to two Evans. And um, it's uhh I 00:12:13.866,00:12:18.871 guess around around 13-14 pounds so, let's see what it does here. [Video plays][smashing noise] So 00:12:21.341,00:12:26.346 that was a coconut [audience murmurs] Here's slow-mo [slow smashing noise] The resolution 00:12:28.648,00:12:35.555 on this video is practically hand drawn. [laughs] [audience laughs] Alright let's see if he 00:12:35.555,00:12:41.294 can do anymore here. [smashing sound] Oh! Man. You would not want to get racked with that. 00:12:41.294,00:12:44.330 Alright, so.[audience murmuring] Uh, that was Milton. Another thing I worked on was Terminal 00:12:44.330,00:12:48.434 Cornucopia and this is something I did uh a couple years ago and uh the project itself spanned 00:12:48.434,00:12:52.872 about a year and a half an uh basically I I uh hypothesized that a a potential attacker 00:12:52.872,00:12:56.809 could go into an airport with nothing but cash, right? Maybe like a small travel proof 00:12:56.809,00:13:01.881 multi-tool and um they could having successfully gotten through security for there's no 00:13:01.881,00:13:06.085 reason not to, just go like to the shops you know and get things that anyone can grab and 00:13:06.085,00:13:10.123 then make potentially de- deadly weapons with it right? So I wanted to to figure out if that 00:13:10.123,00:13:14.927 was uh if that was the case and so I set up some rules. So you can only use materials that can 00:13:14.927,00:13:18.598 be sourced inside the terminal after security screening. Can't walk in with anything but cash 00:13:18.598,00:13:22.902 and a small travel approved multi-tool. And anything you'd get yelled at for taking or 00:13:22.902,00:13:27.106 messing with is completely off limits, right? And I found some crazy stuff in airports in my 00:13:27.106,00:13:32.111 day. Like, uh drills and all sorts of stuff. So I went to a bunch of airports. And things 00:13:34.681,00:13:39.085 that I I like couldn't uh buy commonly you know on the store I would get at the airport 00:13:39.085,00:13:44.590 otherwise I'd just shop at like Walmart or something. Made for some really creepy purchases but 00:13:44.590,00:13:49.629 [audience laughs]. So um I worked on this for about a year, and sort of like you know scaled 00:13:49.629,00:13:54.634 up the uh complexity as I went and here is a supercut of the uh the results. [video begins] 00:14:12.985,00:14:18.324 [background sounds] [classical music plays][blowgun sound][audience laughs][smashing 00:14:18.324,00:14:23.329 sound][audience murmurs][arrow fires][arrow fires][mechanical sound] You use condoms, right? 00:14:55.661,00:15:00.600 [classical music continues] [drill sound] Boop. [click][click] So, completely 00:15:06.272,00:15:11.277 remote incendiary device there. Then I put it in a suitcase. [tiny explosion][larger 00:15:23.156,00:15:28.161 explosion][largest explosion][music begins] >>I came in like a wrecking ball. I 00:15:47.947,00:15:52.952 never hit so hard at love. >>It's a long story. [classical music plays] [smashing sound] 00:16:44.370,00:16:49.375 [classical music continues] [music stops] Safety first guys. [music continues] [explosion] 00:17:12.231,00:17:17.236 [explosion repeats] [music plays] [blowtorch sounds] [metal tearing] [music] [smashing 00:17:58.744,00:18:03.683 sound] [ignition sound] [explosion] [music] [click] [steam hissing] [explosion with 00:19:22.361,00:19:27.366 glass breaking] [music continues] [blade unsheathing] [audience laughs] Yup. [click] 00:19:31.671,00:19:36.675 [audience chuckles] [audience claps] [explosion] [audience laughs] [explosion] [classical 00:20:06.705,00:20:08.741 music continues while rubble falls] [speaker chuckles] [audience laughs] Agh run away! 00:20:08.741,00:20:10.743 [small explosion] [larger explosion] [more explosions] This went on for like half an 00:20:10.743,00:20:12.745 hour. [explosions] Yeah like everywhere. [music and explosions] [sniffs] [explosion] 00:20:12.745,00:20:16.582 [music fades] So hey, you can make weapons ha out of uh stuff you buy in airports [chuckles] 00:20:16.582,00:20:18.584 [audience applauds and cheers]. Awesome. That's a lotta fun. Alright so that was actually the 00:20:18.584,00:20:20.820 really long version of the video I thought that was so I'm going to go through this quickly. So 00:20:20.820,00:20:24.990 this is practical post-apocalyptic electronics. Um I I wa- was worried tha- that 00:20:24.990,00:20:28.060 more and more people don't really understand anything about electricity whatsoever but 00:20:28.060,00:20:32.064 everyone sort of relies on it, right? That's a problem. So I kind of set out to figure out 00:20:32.064,00:20:35.835 like like what's the, what's the least amount of information someone would need to know to to 00:20:35.835,00:20:39.972 like make practical work happen with electricity, right. If they just have the stuff in their 00:20:39.972,00:20:44.210 house. No tools re anything like that. So I so I stayed in a shack in Kentucky. That's like a 00:20:44.210,00:20:50.483 six and a half foot by eleven foot shack with no power in Kentucky, um for about a week 00:20:50.483,00:20:55.488 [video begins] and um it'd been about fifteen years since I'd been in there, it's secure. 00:20:58.257,00:21:03.195 Totes. Aaaaaand there he is. Okay. That is a giant spider [clears throat] so the shack is 00:21:09.168,00:21:12.972 gone and [audience chuckles] Just kidding. [audience laughs] I'm kidding I like lined the 00:21:12.972,00:21:17.343 walls with uh with tarp like I used that foam stuff like all of it [chuckles] in that whole 00:21:17.343,00:21:21.814 city. Uh so yeah I just started building stuff. So um used a you know one of those tchotchke 00:21:21.814,00:21:25.518 flashlights LED flashlights. Mounted that to a full bottle uhl bottle of water acts as a 00:21:25.518,00:21:30.122 diffuser made a nice little centerpiece there. Strung up some lights. Um this is power 00:21:30.122,00:21:34.393 management. I had several ways to power I wanted uh, I wanted to end up with twelve volts and 00:21:34.393,00:21:38.464 five volts, right? Twelve volts is is common with like you know vehicles and um and automotive 00:21:38.464,00:21:43.702 and then uh five obviously is common USB so you're gonna have a a billion batteries that's uhh 00:21:43.702,00:21:47.673 you know regulate at five volts and then um a lot of stuff that consumes five volts, right? So 00:21:47.673,00:21:54.446 um and there's a strong set. Uhh let's see so yeah put this this uh control panel on the wall and 00:21:54.446,00:21:58.651 uh this you know does uh different things. I found a a relay some place. Uh let's see 00:21:58.651,00:22:03.889 this actually uh arms my uh security system in there. So you have to have a key to to disable 00:22:03.889,00:22:07.993 it [laughs]. Or just rip it out the wall I dunno. So uh yeah so the first thing I wanted to do 00:22:07.993,00:22:14.333 is like like sorta like automate things right? So um I found this uh momentary switch, and a leaf 00:22:14.333,00:22:19.338 blower and I wanted to make it so when I walk in, I have it taped down, [bird sounds on 00:22:22.007,00:22:25.945 video] That the light would automatically cut on for me. Isn't that nice?I wanted an 00:22:25.945,00:22:30.049 alarm too right? 'Cause it's Kentucky and you you're just gonna die any minute. So I took 00:22:30.049,00:22:35.554 a head unit out of an old Honda and uh specifically the uh little uh umm uh gear assembly 00:22:35.554,00:22:40.559 that it ejects the uh cd rom, cd rom, cd. And I made a uh a really redneck latching relay. 00:22:44.530,00:22:47.633 [clicking over video] So I wanted uh I wanted this set up to where like when you trigger 00:22:47.633,00:22:51.904 it it's uh it does not be you know become undone by you know undoing the thing you just did 00:22:51.904,00:22:56.041 to trigger it, right? So in this case opening the door. And how this works basically is this um, 00:22:56.041,00:23:00.679 this little mechanism starts winding up and that's uh starts pulling on that that trot line 00:23:00.679,00:23:04.316 which yanks the little piece of plastic out of the way between uh the closepin that have two 00:23:04.316,00:23:08.954 leads on it. That is the only thing separating uh those leads from connecting and um 00:23:08.954,00:23:13.392 completing the circuit on this uh thirty two volts er, er rated nine volts. So. And all of that 00:23:13.392,00:23:18.397 runs down to the weasel. [sniffs] On the wall. [audience laughs] Of course. [sound from 00:23:48.260,00:23:50.262 video] [ignition] [flames crackling and popping ] Ahh friggin' spiders. How's that?! 00:23:50.262,00:23:52.464 [audience chuckles] So yeah. So I got I got off that and and I uh I thought you know the scope 00:23:52.464,00:23:55.668 is a bit too broad. Ss it it it's tough for people to connect with that. So I started looking 00:23:55.668,00:24:00.839 at specific uh pieces of hardware. So like what is our Aurika washer dryer combo? Like 00:24:00.839,00:24:06.745 you know the like for US. So I I started looking at Keurigs and um Keurigs are interesting to me 00:24:06.745,00:24:10.215 for a couple reasons, right? So Keurigs like uh they're in nearly one in every three homes; 00:24:10.215,00:24:15.220 that's a survey done last year. And um uh the the um no lack of critical issues for sure like 00:24:18.090,00:24:22.795 these things break all the time for different reasons across generations and uh if you guys 00:24:22.795,00:24:26.098 you guys've like ever pulled one apart or pulled one open uh, there's a lot of really cool 00:24:26.098,00:24:30.336 stuff in there, right? So, that's a nice recipe. 'Cause you have a lotta a lotta these being 00:24:30.336,00:24:35.474 thrown out and a lot of the the components are still good, right, minus one. And um I 00:24:35.474,00:24:38.811 wanted to know what you can do with that. So I wanted to find like "what's the potential of a 00:24:38.811,00:24:42.948 Keurig?" So I've gotten started on that and here we are. So uh just quick review of the common 00:24:42.948,00:24:47.052 internals, so you'll have a display of some sort. This is usually connected to uh like you 00:24:47.052,00:24:52.791 know you're user interface stuff so maybe some buttons, umm. The more recent models they upgraded 00:24:52.791,00:24:58.230 a bit and they have uh just a a four conductor uh uh resistant touch screen so it kinda cleans 00:24:58.230,00:25:04.036 things up. Um this is kinda the the sort of the main board and this is sort of like a molotov 00:25:04.036,00:25:08.240 of PCB's right so it's like like service mount on the front through a hole in the back. 00:25:08.240,00:25:11.176 Yeeeah. [audience chuckles] Although that's the front I think but it doesn't work as 00:25:11.176,00:25:15.280 well for the joke. So uh lots of little ribbon cables and wires here and there. Uh some of these 00:25:15.280,00:25:19.718 transformers these have like some of them have discrete you know power uh regulation boards 00:25:19.718,00:25:23.155 and all that. Yeah you can like find like nice little breakouts here and there, this is a a 00:25:23.155,00:25:28.394 momentary switch with a couple LEDs. Um you'll find some of these um nice um reed switches 00:25:28.394,00:25:32.631 here, uh these magnetic switches, these uh make sure that you get the lid closed and 00:25:32.631,00:25:37.636 all that. You'll find some bottle caps in there for scale. Uh anyone know what this is? 00:25:40.272,00:25:43.442 [silence] So this is the guy responsible for the DRM In the two dot oh models, 00:25:43.442,00:25:49.515 alright.[audience murmurs] Yeah its a it just reads the levels of uh RGB and A I think. So yeah 00:25:49.515,00:25:53.952 you'll find one of these at least uh one, some kind of pump, uh or some kind of motor 00:25:53.952,00:25:59.124 assembly. Uh uh some of these are really nice, right? This one came out of a Vue and uh it's a 00:25:59.124,00:26:03.896 nice depo motor it's got like built in uh speed control uh it's got a brake on it, it's got 00:26:03.896,00:26:07.800 reverse, it's got a hall effect sensor built in, all this stuff. Uh the newer ones the two dot 00:26:07.800,00:26:11.670 ohs they don't have that they got a regular DC brushless- brushless motor but uh that's 00:26:11.670,00:26:15.774 ok. You'll find some of these uh that's an air pump here and there there's a water pump on 00:26:15.774,00:26:19.978 the right. The old ones have these solenoids which is nice. Uh the new ones they they sorta 00:26:19.978,00:26:24.983 did away with that. All of them will have a boiler of some sort. Here's one right here. And um a 00:26:29.388,00:26:33.992 ton of uh both flexible and rigid tubing and uh there's all these connectors and stuff that 00:26:33.992,00:26:38.130 you would put in a sock if you wanted to kill someone in prison [audience chuckles]. And a whole 00:26:38.130,00:26:42.935 lotta plastic right? Different types of plastic, brittleness, thickness, you know all that 00:26:42.935,00:26:47.473 stuff right. So, man! You could do a lotta stuff with that, right? Anyone's like, you know, 00:26:47.473,00:26:53.645 wheels turning here? Mine surely were. So uh just a quick disclaimer um I don't represent 00:26:53.645,00:26:58.050 Keurig in any way. I I'm actually a customer I use mine a couple times a day I work at 00:26:58.050,00:27:02.888 home. Uh I say what I want uh spaghetti. So [audience chuckles] um first thing I 00:27:02.888,00:27:08.961 wanted to do is is look at look at uh a thermal energy of a Keurig working normally and so 00:27:08.961,00:27:13.499 um I did that. Basically um who in here thinks that that Keurigs when they boil they boil under 00:27:13.499,00:27:18.504 pressure, when the water heats up? There's one guy, so. No they actually they boil into the 00:27:22.307,00:27:26.111 atmosphere so that was disappointed about that. So basically water heats up in the 00:27:26.111,00:27:30.916 boiler and then um uh a different pump rams air into that and forces it out over your 00:27:30.916,00:27:36.455 coffee grounds into your cup, right? Excellent. So I wanted to figure out how to really disturb 00:27:36.455,00:27:40.926 that process so I started working on WoRPaW! Which is an acronym for the worst part of 00:27:40.926,00:27:45.164 waking up. [Audience chuckles] So I you know started taking it apart and and keep in mind guys 00:27:45.164,00:27:50.369 this is not like an exploit or anything this is like straight up sabotage [chuckles] right? 00:27:50.369,00:27:54.206 [laughs] Like there there's no uh [laughs] there's no disclosure here. Yeah so uh you 00:27:54.206,00:28:00.579 know yg- you got AC comin' in and um that connects here to our main board, right? And then it 00:28:00.579,00:28:05.183 eventually goes back out to these heating elements. But not before passing through uh these 00:28:05.183,00:28:11.390 two guys. And umm these are both uh uh heat related. So the bottom one is a uh an SE fuse, 00:28:11.390,00:28:17.095 it's got a little um uh organic thermo uh sensitive compound, and it's it's uh crafted in such 00:28:17.095,00:28:20.499 a way that if it gets you know reaches a cer- certain temperature it melts down, 00:28:20.499,00:28:26.071 spring disengages, and it it you know separates your your um uh your your circuit forever right? 00:28:26.071,00:28:29.641 The top one it just uh either stays on or off until it reaches a certain temperature and then 00:28:29.641,00:28:34.680 it it flip flops. Also this guy, it's a little pressure sensor right? Little tube running into 00:28:34.680,00:28:37.583 the bottom. I would imagine that probably has something to do with whether or not they're 00:28:37.583,00:28:44.590 going to power you know the the uh heating element on the boiler. Bless you. So um if only 00:28:44.590,00:28:49.394 there was a way to uh to bypass you know all of this logic- oh right wire ties! So 00:28:49.394,00:28:54.099 yeah.[audience chuckles] Um now we've got a you know one twenty volt AC going directly to the 00:28:54.099,00:28:57.803 the heating element, so that should be good. But we still have the the issue of these 00:28:57.803,00:29:02.741 three guys here right? Oh yeah right so uh JB valve. That'll do it. Cool so yeah. Umm now we've 00:29:05.644,00:29:11.116 got a boiler that's got water in it, that is uh should be sealed, right? and umm [video begins] 00:29:11.116,00:29:16.121 Let's see what happens. [steaming sound] Awwwwwww. [continued steaming] All of our 00:29:27.466,00:29:32.471 precious pressure. [more steaming sounds] And it's. Look at it thermally, it looks 00:29:36.375,00:29:41.380 normal. Until it just like all of the sudden turns into satan's butthole and the thing just goes 00:29:44.116,00:29:49.187 sideways.[sounds continue] So I actually left this on to see if like anything else would happen. 00:29:49.187,00:29:52.658 I didn't figure it would, it just got hotter and hotter until like the the whole house started 00:29:52.658,00:29:56.461 smelling like sat- satan's butthole, and then I cut it off [audience chuckles] Because it 00:29:56.461,00:30:01.500 was on fire pretty much, you know? [audience laughs] It got super melty [laughs] It really 00:30:01.500,00:30:05.637 smelled awful. Good grief. But yeah no I figured that you know our our seals failed but they 00:30:05.637,00:30:10.976 did not! Actually uh it was a different result and um both of er were uh all three of our 00:30:10.976,00:30:17.382 seals were intact. What happened was um, it just got too hot. Like the whole top sorta like 00:30:17.382,00:30:21.987 melted and slid to the side and just let all the pressure out, right? So that was kind of a 00:30:21.987,00:30:26.191 bummer, I wanted it to explode and all that. But it's okay, because science, right? That's a 00:30:26.191,00:30:31.697 result, now we know, so uh we can sorta move on to to new things. So um the next thing I I 00:30:31.697,00:30:35.767 worked on right, er actually this was at during a conference I um I built a DeBBUG.And this 00:30:35.767,00:30:41.740 is uh th- a delicious uh beverage dispensing badge of unmitigated glory. And so 00:30:41.740,00:30:48.246 basically um you got a uh solenoid and an air pump. Uh uh one button pumps air into the uh 00:30:48.246,00:30:52.451 container with the delicious beverage, and then um when you um press the other button to 00:30:52.451,00:30:58.256 disengage the solenoid. That uh has to go somewhere so it comes out the little spout just like 00:30:58.256,00:31:03.195 this. [video begins] [liquid dripping] Ahh. [liquid dripping] Good job fella. [audience 00:31:11.870,00:31:15.073 chuckles] So when I travel with this, I like to leave a note, just to be just to be nice I 00:31:15.073,00:31:20.645 guess, 'cause it looks, it looks sketchy man. [audience laughs] Seriously [laughter] although I 00:31:20.645,00:31:25.917 must say every time I've traveled with this my my luggage has not been searched. Soo... 00:31:25.917,00:31:27.919 [audience chuckles] Or at least they're not leaving notes any more I don't know. Do they leave 00:31:27.919,00:31:32.924 notes still? They leave notes, right? Oh man. Anyways so yeah um mov- moves on to my uh, my my 00:31:36.361,00:31:39.865 big bill here and this is this is HEDBERG [light audience noise] And uh, that's not an 00:31:39.865,00:31:43.735 acronym at all. Uh so I, I wanted t- I wanted to build something that was um, 00:31:43.735,00:31:48.974 moderately complex, it had to had to have some precision to really sort of work well, and um 00:31:48.974,00:31:54.146 I started looking at at these uh prosthetic hands, right? And these are cool because like 00:31:54.146,00:31:56.948 there's some really nice ones. This one's like I think eighty grand, something like that 00:31:56.948,00:32:01.253 something insane. But also there's some really great work happening in like the 3D space, 00:32:01.253,00:32:04.923 right? Like you could print these for ten bucks! And they they function they're great. You 00:32:04.923,00:32:07.893 get to like as soon as you outgrow them you just print another one, so not a big deal, 00:32:07.893,00:32:13.398 ya know? Um and it's all open source, and it's great right? So I kinda wanted to see where umm 00:32:13.398,00:32:17.502 where I could get you know um just eh relative to both the you know I guess the commercial 00:32:17.502,00:32:21.439 product, right, which is crazy and then sort of what uh people are doing with uh with additive 00:32:21.439,00:32:26.912 printing. So uh I started making some junk prototypes just to sort of feel out um what was 00:32:26.912,00:32:32.484 possible. Get a get an idea of how the materials work together and so I you know I just started 00:32:32.484,00:32:37.689 tinkering with uh with different mechanisms just to, I don't know see what works and what didn't. 00:32:37.689,00:32:41.126 [sound from video] So there's that. I started uh you know dealing with these little finger 00:32:41.126,00:32:45.263 guys. 'Cause really I think the the digits were were the thing I wanted to to really kinda nail, 00:32:45.263,00:32:49.467 that's sort of the uh the linchpin right? So I tried a different couple different 00:32:49.467,00:32:54.372 designs, did a lot of research, saw what other people were doing. And um I felt like you 00:32:54.372,00:32:58.043 know based on all that knowledge, I I could go ahead and start my build right? So I 00:32:58.043,00:33:03.448 started working on HEDBERG and um a couple things to uh to note here I used a one single Keurig, 00:33:03.448,00:33:08.453 right? Uh one single um K three fifty err three hundred kinda the same thing. And um uh only 00:33:10.555,00:33:15.827 external materials in in the um in the head the end products are adhesives, and I think there 00:33:15.827,00:33:20.565 were a couple of iterations in design. You probably uh do away with a lot of that. I just used 00:33:20.565,00:33:25.704 basic tools. You know I didn't wanna like you know how you watch a uh a video on youtube or 00:33:25.704,00:33:28.540 something and someone makes something cool and it's like well yeah they've got a pristine 00:33:28.540,00:33:33.178 shop with like every tool imaginable, right? So we're like I don't know, that's kinda 00:33:33.178,00:33:38.016 cheating right? So I just use a a dremel basically and a heat gun and some hand tools, files, 00:33:38.016,00:33:43.655 stuff like that. Uh no plans for this just uh just sort of you know making it up as I go along 00:33:43.655,00:33:47.692 [breathes] and so um at the end of the day it was uh a hundred and ninety nine hours sixty-six 00:33:47.692,00:33:53.565 minutes and thirty-six seconds of working time. So that's that's uh time at the bench, um 00:33:53.565,00:33:57.769 you know with my hands on materials doing things and manipulating stuff. And guess 00:33:57.769,00:34:02.707 what? I recorded every second of that. And you're gonna see it now [audience laughs]Settle in. 00:34:17.956,00:34:22.961 [video begins] [box moving] You have to drum on it to get it started. [more box sounds] It's 00:34:42.781,00:34:47.786 every second of this whole build, settle in [Clair De Lune plays] [music continues][video 00:38:06.985,00:38:11.990 ends]Heyyy!! [audience applauds] That's HEDBERG! [more applause] [HEDBERG working] Beautiful. 00:39:40.678,00:39:47.151 Thank you for working. [audience applause] So of course I made a case for it, and uh of course it 00:39:47.151,00:39:52.156 was a an issue with TSA [laughs] [audience laughs] So yeah uh let's talk about the features 00:39:52.156,00:39:55.560 real quick so it's got distributed grip pressure. I used a sort of a fulcrum here in 00:39:55.560,00:40:01.065 the middle so um if uh if there's some more pressure on like one side of the hand or 00:40:01.065,00:40:03.935 some side of the fingers or the other it it sort of like compensates with the other uh 00:40:03.935,00:40:09.507 other side. It has a an official gangster electronic speed controller on it so uh there are 00:40:09.507,00:40:14.212 no like five five five timers or no like components necessary to build a traditional one. So uh 00:40:14.212,00:40:18.016 the issue was the the regular motor. It just moves too quickly right? Your hand would just be 00:40:18.016,00:40:21.719 like going crazy it has no control so umm I had to improvise. So usually the way 00:40:21.719,00:40:25.690 this is done is with a pulse with modulation. Umm so like think about an LED it's either 00:40:25.690,00:40:30.228 on or off, right? But you could dim them by turning them on and off really really fast and then 00:40:30.228,00:40:34.532 like it d- gets more dim when you have it on less than you have it off. Makes sense? So 00:40:34.532,00:40:39.671 yeah um the way I did that uh is I basically took uh one of those motors and I took a piece of 00:40:39.671,00:40:43.074 plastic in the middle and uh mounted a magnet on one side of the thing that spins in the 00:40:43.074,00:40:48.079 middle. And then uh on the other side I just mounted a magnetic switch, right. So uh you end up 00:40:50.348,00:40:55.887 with something like this and there's the little uh screw there to adjust the um uh the 00:40:55.887,00:41:01.893 amount of of uh exposure that umm uh magnetic switch actually gets with the magnet. So it it 00:41:01.893,00:41:07.632 it actually increases or decreases the pressures. You can see it working here. [mechanical 00:41:07.632,00:41:14.472 noise]Makes sense? So every time that magnet swings around and it trips that se- sensor it puts uh 00:41:14.472,00:41:18.109 twelve volts in that that motor, your hand moves forward just a little bit more. So slowing it 00:41:18.109,00:41:21.946 down, I thought about using friction but that's probably a bad idea so uh you have to drop 00:41:21.946,00:41:26.918 the voltage. Tried a voltage divider. The the resistors actually in in the um uh Keurig 00:41:26.918,00:41:32.023 were were not rated high enough and these started smoking, that's bad. So um eventually um 00:41:32.023,00:41:36.627 my I call my brother and he was like "yeah just, you know diodes they they drop the voltage about 00:41:36.627,00:41:39.997 point seven volts". And there were like nine of them in the Keurig, so I just chained a 00:41:39.997,00:41:44.202 bunch of them together so. [chuckles] It works just fine, doesn't get too hot. You know 00:41:44.202,00:41:47.805 there are some room for improvements of course I built it so to me it's perfect. Umm 00:41:47.805,00:41:51.175 but yeah you know if you put a microcontroller and a few components in this thing, like 00:41:51.175,00:41:55.713 it would be ridiculous right? So you could you could start using that uh color sensor.You could 00:41:55.713,00:41:59.684 use that to get feedback on where the fingers are potentially uh all sorts of 00:41:59.684,00:42:04.255 things. You could um actually like you implement analog input you could you know control the 00:42:04.255,00:42:08.626 uh you know the speed and all that stuff. Umm you know just using a microcontroller would be 00:42:08.626,00:42:14.332 really simple, um of course I I didn't have that luxury here. Um but yeah you can um do all this 00:42:14.332,00:42:18.536 cool stuff. So what's next for this the Keurig stuff? Um I want to look at like water filtration 00:42:18.536,00:42:22.874 and purification. I want to look at cooking, I think that'd be fun. Uh I think uh there's some 00:42:22.874,00:42:27.178 like i- interesting applications for gardening maybe some hydroponics? Uhh I would like to 00:42:27.178,00:42:31.449 build an aquarium 'cause that'd be funny. Um meta what ab- what about like building something 00:42:31.449,00:42:35.753 that would help you build other stuff? Eh? Uh but one thing that I I've actually started on and 00:42:35.753,00:42:40.658 and got some headway going here are uh firearms. So I might be the first person to actually 00:42:40.658,00:42:45.229 shoot a Keurig. Uh so where do we go from here? Uh real quick 'cause we're we're like short on 00:42:45.229,00:42:51.102 time. Guys the stuff surrounding us all the time has like huge amounts of potential. Huge! Like 00:42:51.102,00:42:57.208 everybody everybody long pants long pants right.Humongous. And um if the if the thing that like 00:42:57.208,00:43:00.778 gives you like mediocre coffee every day could could actually like help someone pick something 00:43:00.778,00:43:05.483 up who normally couldn't like like that that represents a huge gap in in like what we're using 00:43:05.483,00:43:08.953 it for and what what the act- actual potential this thing is, right?So, um frequent 00:43:08.953,00:43:14.892 Macgyvering it it lets you, it let's your brain naturally find more uh interesting and and 00:43:14.892,00:43:19.464 clever solutions to everyday problems. It's just a good like mental exercise. Uhh also if 00:43:19.464,00:43:23.301 you're stubborn enough, everything is sandpaper [audience laughs] [coughs].And 00:43:23.301,00:43:26.904 winter is coming! So [sighs] for this project it was it was all it was almost two hundred two 00:43:26.904,00:43:29.273 hundred hours long and like the first part was great 'cause I got the fingers going and I was 00:43:29.273,00:43:32.577 like "yeah fingers!" And now I'm like aw crap now I've gotta like actually make make this work 00:43:32.577,00:43:37.348 consistently and like, you know like drudge through the the slow and tedious parts and you know 00:43:37.348,00:43:42.520 fail and try things again and all that stuff so. That was umm that was tough. And it's it's 00:43:42.520,00:43:47.625 good to it's good to know that going in and like get mentally prepared for it just so you can 00:43:47.625,00:43:53.064 actually finish finish the project right? Uh big one is man take everything apart. This is a 00:43:53.064,00:43:59.904 huge skill. I don't care if it's yours or not, I'm not the police but dude like like if you get a 00:43:59.904,00:44:03.541 enough experience with this thing right. Taking something apart will eventually become 00:44:03.541,00:44:08.246 like having a conversation with the engineer who built it. Which is pretty cool, because like as 00:44:08.246,00:44:11.949 I'm taking stuff apart I'm like "Why is this here?" Like "Ohhh this is this is pressure fit I 00:44:11.949,00:44:15.720 don't have to use any screws here, that that's great."So yeah um I wanted to thank a few 00:44:15.720,00:44:19.624 awesome people real quick. Uh my mom first and foremost. The the the time lapse video, I knew I 00:44:19.624,00:44:24.328 wanted Clair De Lune in it 'cause that's one of my favorite like Vegas songs, I- for a lot 00:44:24.328,00:44:28.799 of reasons, and um it's actually in public domain but all the recordings uh were were kinda 00:44:28.799,00:44:34.672 pricey. Uh my mom is uh a a pianist um and so I eh my wife had the idea was like "call your 00:44:34.672,00:44:39.310 mom" I was like "ehh y'know eh okay" and she like ran off in a storm and recorded that for me. 00:44:39.310,00:44:43.214 And uh that will be available in the public domain uh if you guys wanna download it. Uh I'll put a 00:44:43.214,00:44:48.219 link in my twitter. Eventually. Umm [audience applauds]Yeah thanks mom. [applause]Uh Dan 00:44:51.055,00:44:56.060 Teller right here umm he he let me borrow his uh thermal cam for like like months and uh and last 00:44:58.262,00:45:02.900 night I was like you know I had an I need some Vegas footage here. It was like nine o'clock. 00:45:02.900,00:45:06.871 I was like Dan, do you wanna shoot some stuff? And a couple like a couple drinks later it 00:45:06.871,00:45:11.876 was like two AM we had some like freakin' amazing footage so thanks for that, Dan. Uh my 00:45:11.876,00:45:14.779 brother Taylor he would uh be available on the phone for like electronics questions he's an EE 00:45:14.779,00:45:19.383 and all that stuff. And most of all you guys, right? So I"m talking to you guys and uh and 00:45:19.383,00:45:23.321 you guys absolutely blow me away with the stuff you're working on. And like and the struggles 00:45:23.321,00:45:26.757 that you're going through with it and I it occurs to me that like, a lot of you you probably 00:45:26.757,00:45:31.062 like carrying the flag, you know all by yourself on a lotta this stuff. And a lot of this stuffs 00:45:31.062,00:45:34.932 like all your projects are really important. Even like your side projects. So I just wanna 00:45:34.932,00:45:39.337 encourage you guys like like like, keep your head up with that. Like even if the the 00:45:39.337,00:45:43.808 number of people supporting you is zero like, that's alright, you know? Come to these things 00:45:43.808,00:45:49.480 and find people who who get you and help you you know be you and and like get your get your 00:45:49.480,00:45:54.485 awesome projects going. So. Guys thanks so much go build some stuff. [audience applauds 00:45:56.921,00:45:59.590 heartily] Awesome!
