WEBVTT 00:00:00.080 --> 00:00:06.640 Every so often, some brand or another takes a stab at a modular or upgradeable 00:00:04.640 --> 00:00:11.759 laptop. And as someone who does an awful lot of PC building and is very pright to 00:00:09.200 --> 00:00:16.000 repair, I am so here for it every single time. I even invested my own money in 00:00:14.400 --> 00:00:20.880 framework to show my support for the dream. But alas, a dream remains because 00:00:18.880 --> 00:00:24.960 almost all of these efforts end up discontinued before they even become a 00:00:22.960 --> 00:00:31.359 real product. Which raises the question, if all these big companies can't do it, 00:00:27.680 --> 00:00:33.760 how come this guy can? Byron here 00:00:31.359 --> 00:00:39.520 customd designed, built, and open-sourced his own ARMPowered laptop 00:00:36.719 --> 00:00:45.360 in just 6 months. But it's a shockingly potent machine. I'm talking a 4K AMOLED 00:00:42.640 --> 00:00:50.800 screen, CherryMX mechanical keyboard, and a custom machined aluminum chassis. 00:00:47.920 --> 00:00:54.239 And the guy's still in high school. Then he casually throws together this highly 00:00:52.800 --> 00:00:58.239 polished video showing how he did it. I mean, have you seen my first videos? 00:00:56.399 --> 00:01:03.199 Obviously, I had to meet this guy. So, uh, hang on one second. Hey, Byron. Zoom 00:01:00.640 --> 00:01:07.520 is just so impersonal. So, I flew Byron out here so I could check out 00:01:05.000 --> 00:01:12.799 the Anonyi. Yes, Anonyi. Yes, in person. And my 00:01:10.720 --> 00:01:17.920 first question for you is, do you dance? I do. Really? Do you know the uh here? 00:01:15.840 --> 00:01:21.920 Do you know the segue?

Didn't notice how bad the quality was. 00:01:54.399 --> 00:02:01.520 It was funny you say that because as I was walking up to set earlier, I saw 00:01:58.640 --> 00:02:07.560 your machine. I thought it was mine. I am impressed at how good it looks. 00:02:04.880 --> 00:02:14.000 Actually, this is incredible. Oh no, you broke it already. 00:02:12.080 --> 00:02:16.480 Wow, that was actually really quick even for me. Okay. What happened? It's all 00:02:15.360 --> 00:02:21.360 right. I don't really know. Wait, did you just throw it away? Yeah, that was a 00:02:18.640 --> 00:02:24.480 screw. It's okay. Screw, you know, bad quality. But the important thing is that 00:02:22.640 --> 00:02:27.120 it's still all together, right? Do you want to put the screw back? No, it's all 00:02:25.840 --> 00:02:31.760 right. Cuz I think I have the perfect tool for you. What is it? 00:02:30.400 --> 00:02:36.720 What are you talking about? From ltstore.com. Yeah, let's go. My first 00:02:34.640 --> 00:02:40.400 and maybe most important question is why? When I set out to b make this 00:02:38.720 --> 00:02:44.319 laptop, I really wanted to focus on creating something. 00:02:43.120 --> 00:02:50.959 That's going to be the memes forever now, right? That's going to that's going to be in the drop reels going on in the 00:02:48.319 --> 00:02:54.239 future. You set me up. I did. You set me up. I did. Yeah. It looks like you 00:02:52.239 --> 00:02:58.239 didn't watch the video I made. I skipped through a little bit. Yeah, I can tell. 00:02:55.920 --> 00:03:01.440 Well, see, here's the thing. Whenever I know that we're going to be making a 00:02:59.680 --> 00:03:05.920 video about something, I go out of my way to cloister myself. I don't want to 00:03:03.840 --> 00:03:11.519 learn any more about it than I have to. The keyboard. Yep. I know it's Cherry 00:03:08.239 --> 00:03:13.920 MX. That's right. Um I know that it was 00:03:11.519 --> 00:03:17.120 custom made including the key caps. That's right. You know that there are 00:03:15.280 --> 00:03:21.599 commercially available laptop keyboards, right? So what inspired you to take this 00:03:19.760 --> 00:03:24.959 detachable approach? So when I set out to make it, I really wanted to focus on 00:03:23.519 --> 00:03:28.959 creating something that the keyboard will be a centerpiece of the laptop. And 00:03:27.360 --> 00:03:33.599 when I can't focus on the performance of the chip itself, I'm limited to, you 00:03:30.879 --> 00:03:36.879 know, a crappy rock chip RK3588. I wanted to make the laptop stand out in 00:03:34.959 --> 00:03:41.360 other aspects like the 4K AMOLED display and of course this wireless removable 00:03:38.959 --> 00:03:44.640 keyboard. The entire battery is enclosed in here and it is a fully wireless 00:03:43.360 --> 00:03:48.799 Bluetooth keyboard. So it just, you know, simply slots in to the laptop 00:03:46.560 --> 00:03:51.519 chassis magnetically like so. And you can use it on another laptop, you can 00:03:50.319 --> 00:03:56.959 use it on this laptop, whatever you want. Putting in Cherry MX mechanical switches was a challenge that I really 00:03:54.799 --> 00:04:00.879 wanted to do cuz I I love mechanical keyboards. You never actually answered 00:03:58.560 --> 00:04:04.239 the question of why. So, in the past, I really worked on a lot of open source 00:04:02.239 --> 00:04:07.599 electrical engineering projects. And so, I've worked on various parts of what 00:04:06.000 --> 00:04:13.519 might be considered a laptop system like power systems, um, keyboard, compute, 00:04:11.120 --> 00:04:16.799 display driving, human input. I worked for Keyron in the past designing a new 00:04:15.360 --> 00:04:21.680 product. After making all those things, I really wanted to put everything together into this one cohesive package 00:04:20.079 --> 00:04:26.400 and make it open source for everyone to see. I'm going to try to use the keyboard first cuz we haven't even 00:04:24.960 --> 00:04:29.280 powered this on yet. I want to have that experience a little bit later. I want to 00:04:28.080 --> 00:04:35.040 connect the keyboard to my laptop. All right, great. So, I would assume there's a pairing button. So, no, there isn't. 00:04:33.680 --> 00:04:40.240 There is not. There's also no off button on this keyboard. It's always on. Wow. 00:04:37.520 --> 00:04:44.000 Yeah. Uh, good. Yeah, of course. Convenient. It is. It's always on. And 00:04:42.800 --> 00:04:48.000 the reason it can do that is cuz it's on ZMK, so it runs almost a year on a 00:04:46.160 --> 00:04:54.479 single charge. No way. Yeah, almost a year. I haven't charged it really since I I built it. 94%. It even has battery 00:04:52.560 --> 00:04:59.600 life reporting. Yep. You got to be kidding me. Yeah, that is very cool. 00:04:57.520 --> 00:05:03.840 Also, I cheated a little bit while you were distracted. I pressed down on one 00:05:01.440 --> 00:05:08.320 of the keys. That is a shocking amount of travel. 00:05:06.800 --> 00:05:12.720 That's right. Considering how thin this thing is. Yep. Yep. Like it's it's like 00:05:10.400 --> 00:05:16.000 it goes all the way down to the PCB. Every single slice of this keyboard has 00:05:14.320 --> 00:05:20.320 been designed to be as thin as possible. If someone brought this to me as a V1 00:05:17.759 --> 00:05:25.440 prototype of a product, I'd be like, "Fuck, send it." Yeah. Cuz this is 00:05:23.759 --> 00:05:30.639 awesome. I don't know if you know this, but I'm actually a 915 TKL user. And 00:05:28.880 --> 00:05:34.479 what I love about it is that it's a desktop keyboard, but it's it's super 00:05:32.720 --> 00:05:38.240 low profile, and I love the I love the feel of the key switches. I would say 00:05:36.639 --> 00:05:42.479 there's a little work to do on the profile of this before it was a retail 00:05:39.840 --> 00:05:47.360 product, but in terms of the feel, like what you've accomplished here is 00:05:44.800 --> 00:05:50.800 outstanding. Yes, he knows it. Thank you so much. Thank 00:05:48.960 --> 00:05:55.680 you. He knows it. Thank you. It has a 00:05:52.360 --> 00:05:57.199 shockingly typewriteresque sound. Yeah, 00:05:55.680 --> 00:06:01.280 I actually kind of love it. Here, hold on. You got to kind of here. You got to kind of hear it up 00:06:02.039 --> 00:06:09.319 close. Like it almost it has a bit of a clang, which in the mechanical keyboard 00:06:06.479 --> 00:06:14.319 space is not quote unquote desirable, but it does it in kind of a 00:06:11.680 --> 00:06:17.680 cool way. I guess my next question is how confident were you going into this 00:06:16.240 --> 00:06:23.440 that you would be able to build something resembling like I said I 00:06:20.000 --> 00:06:26.400 mistook it for my own machine right a 00:06:23.440 --> 00:06:31.680 real laptop. I'm calling mine a fake. No. Uh I'm calling it not commercial. Ah 00:06:29.840 --> 00:06:35.919 yeah. Yeah. I set myself really really high bars. Like I looked at a Framework 00:06:33.919 --> 00:06:40.800 13 and I looked at a 14-inch MacBook Pro. I tried to make as many comparisons 00:06:37.680 --> 00:06:42.639 as I could to them and accomplish as, 00:06:40.800 --> 00:06:45.600 you know, as close as I possibly could. The confidence pretty much zero. Why 00:06:44.400 --> 00:06:50.400 don't we talk about the thing that really sets this machine apart from 00:06:47.520 --> 00:06:55.639 other DIY laptops, and that is the machined body. There's less flex than 00:06:52.160 --> 00:07:00.080 yours. Hold on. Let's validate this. 00:06:55.639 --> 00:07:02.319 Okay. Okay. That's a lot of flex. 00:07:00.080 --> 00:07:06.080 Pretty good. I think that is I've never done that to it. I'm just too scared. 00:07:04.160 --> 00:07:11.360 Yeah. Well, it didn't break. So, that's a 00:07:08.240 --> 00:07:13.680 Yeah. Yeah. Let's go. So, in choosing 00:07:11.360 --> 00:07:16.800 the chassis design and the material and the annotization, I made a bunch of 00:07:14.880 --> 00:07:20.960 these cubes. This is half of the cubes I evaluated. And so, in the end, I settled 00:07:18.720 --> 00:07:24.479 on this one. The reason I know it's this one is cuz I actually like milled into 00:07:22.240 --> 00:07:28.880 it. So, I knew how malleable the metal was if I had to modify it later on. Oh, 00:07:26.720 --> 00:07:33.840 got it. So you were looking both at the finish and at the actual material 00:07:31.360 --> 00:07:38.639 because we say, "Oh, it's made of aluminum, but almost nothing is made of 00:07:36.960 --> 00:07:42.319 pure aluminum. It's made out of some aluminum alloy and they have very 00:07:40.720 --> 00:07:47.360 different properties potentially. The unibody design is quite special than a 00:07:44.639 --> 00:07:51.599 traditional laptop. The palm rest or the mid plate as I call it actually screws 00:07:49.280 --> 00:07:55.680 in from the top and the the reason stems from the actual keyboard being a 00:07:53.360 --> 00:08:00.479 removable detachable piece. So, I wanted it to just slide right in. And the most 00:07:58.639 --> 00:08:03.680 optimal position to do way to do that would be by having the bottom completely 00:08:02.319 --> 00:08:08.400 screwless. There's nothing behind it. And you just machine out basically this 00:08:05.759 --> 00:08:13.039 bottom shell and then the top shell. And then you put framework hinges this 00:08:10.720 --> 00:08:17.199 closure, right? Yeah. Yep. All right. So, you put these hinges in and you 00:08:14.960 --> 00:08:20.720 just, you know, it'll come together just like that. Obviously, it's a it's a 00:08:19.199 --> 00:08:25.680 function first design, but I want to have a quick philosophical conversation 00:08:22.319 --> 00:08:27.599 with you. Personally, I don't like 00:08:25.680 --> 00:08:33.519 seeing the function of a product harmed by this. I feel irrational desire to 00:08:30.240 --> 00:08:35.760 hide screws. Y do you think it's okay to 00:08:33.519 --> 00:08:40.320 just have some screws visible on something? Of course. I mean, why not? 00:08:38.399 --> 00:08:43.760 If you get to where you need to go, screws are the way. I also have duct 00:08:41.919 --> 00:08:47.920 tape there, you know. Okay. There's only two types of screws. Uh there's only 00:08:45.120 --> 00:08:51.519 Torx and Phillips on there. Nice and repairable. And now we're pulling up the 00:08:49.360 --> 00:08:57.200 CAD. So, this is the bottom chassis itself. And no wonder it's so rigid. 00:08:54.000 --> 00:08:59.200 Yeah, it is fully CNCed and and heavy. 00:08:57.200 --> 00:09:06.800 What? It's a little heavy. Oh, yeah. Oh, yeah. Hefty. Yeah, hefty. Yeah, I missed 00:09:01.839 --> 00:09:09.200 the F. He t There's a lot of different 00:09:06.800 --> 00:09:13.360 parts that come fitting that comes to fit into the actual chassis, including 00:09:11.120 --> 00:09:17.040 the two framework 13 hinges. Yeah. And then so the powertrain board mounts 00:09:15.279 --> 00:09:21.279 right over here. Yeah. And then the actual main compute board, I call it the 00:09:19.200 --> 00:09:24.800 main board or the motherboard goes right here. Do you call it that? Did you come 00:09:22.720 --> 00:09:29.839 up with that term? No. Main board. I didn't, but I call it that. Um, and so, 00:09:28.160 --> 00:09:32.800 and then here we have four individual battery cells. And I wanted to make 00:09:31.200 --> 00:09:35.920 these battery cells separate. One is for safety. I didn't want to blow up like 00:09:34.399 --> 00:09:40.959 the entire laptop when I was sleeping, but it also allows me to build a custom 00:09:38.720 --> 00:09:45.279 battery pack so I can specify to however much I want. This can actually discharge 00:09:43.040 --> 00:09:48.399 150 watts at any given moment, but obviously it won't ever do that. But, 00:09:46.640 --> 00:09:54.640 you know, just for a rock chip, not on a rock chip. Here on the left side, we 00:09:50.399 --> 00:09:56.320 have um two USB-C 3.1 Gen 2 ports. I 00:09:54.640 --> 00:09:59.040 don't have the firmware to support a external display on them just yet, but 00:09:57.760 --> 00:10:03.680 you know, maybe in the future. In the many revisions I made with the laptop, I actually have three separate designs for 00:10:01.839 --> 00:10:06.640 the main board. I switched from an HDMI, which didn't really work, and the signal 00:10:04.959 --> 00:10:10.560 integrity was a little off. I switched to a USB 2.0 port at the very end. And 00:10:09.040 --> 00:10:15.279 also just cuz I was mad that you know how how how can a MacBook not fit a USB 00:10:12.880 --> 00:10:18.240 2.0, you know, a USBA port in there. And this is no thinner. This is This is no 00:10:16.880 --> 00:10:25.519 thicker. Since we're at it, why don't we look at the rest of the IO? You've got a micro SD reader. Nice to see. Headphone 00:10:22.560 --> 00:10:29.440 jack. Doesn't work. Oh, yeah. Bad engineering. Oh, yeah. It just didn't 00:10:27.600 --> 00:10:33.040 work. I don't know why. And then this is a power only input, right? So, you 00:10:31.600 --> 00:10:36.079 cannot charge the battery from this side, I would assume. Fortunately, no. 00:10:34.720 --> 00:10:39.440 The reason you can't charge from these USBC ports is because I wanted to 00:10:38.160 --> 00:10:44.959 separate the compute and the power system so they individually function first to save the timeline. This looks 00:10:43.279 --> 00:10:47.920 great, by the way. This is very classy. Yeah, I really like that. So, did you 00:10:46.480 --> 00:10:55.680 just take it to a third party shop to have it machined out? I did. I got it CNC by JLC. It didn't cost that much. It 00:10:52.000 --> 00:10:57.600 only costed around what $300 to $500 00:10:55.680 --> 00:11:01.120 really for the entire chassis, every metal piece combined. And that included 00:10:59.360 --> 00:11:04.640 the cost of the metal? Yes, it does. And the anodization. So, it came to me fully 00:11:02.880 --> 00:11:08.320 blacked out already. Oh, dude. I would have guessed over a,000 for sure. You 00:11:06.800 --> 00:11:12.399 want to take a guess at how much this laptop costed? R&D everything added up 00:11:10.240 --> 00:11:16.959 together. How are you calculating the R&D? What are you billing out at? Every 00:11:15.680 --> 00:11:22.480 everything that I bought, everything that I bought to make this laptop. So, just parts. Just parts. Every failed 00:11:20.320 --> 00:11:25.360 revision, every, you know, misinput, everything that I had to buy cuz I 00:11:23.680 --> 00:11:28.880 burned it. All of that added up. So, really, I should be looking more at you 00:11:27.040 --> 00:11:36.640 than at that because it's like, how much would he burn? How much would he 00:11:32.360 --> 00:11:40.240 destroy? a lot. I'm going to say what? 00:11:36.640 --> 00:11:44.079 5K. You're spot on. It's around 4.8. 5K. 00:11:40.240 --> 00:11:46.399 Yeah. Yeah. I still got Oh my god. Yeah. 00:11:44.079 --> 00:11:52.000 Well, look, we've developed a number of products ourselves. So, I have some idea 00:11:49.040 --> 00:11:55.279 of what the failure rates are like when you're trying to figure stuff out. This 00:11:53.760 --> 00:11:58.800 is it. Big moment. I get to turn it on now. I have expected it to make like a 00:11:57.120 --> 00:12:03.120 MacBook noise or something. I I don't know if you're an Apple fan. Turns on a 00:12:00.160 --> 00:12:07.120 bit. There it goes. Oh, dude. You got like a you got like a splash screen and 00:12:04.959 --> 00:12:10.560 everything. That's cool. Thank you. I still remember when I set up my old 00:12:08.720 --> 00:12:16.720 machine when I was about your age to have a uh to have a Jolly Rodger for the 00:12:13.680 --> 00:12:19.680 Windows XP loading screen and it said 00:12:16.720 --> 00:12:26.399 Windows XP Pirate Edition. I might not be alive for that. 00:12:23.040 --> 00:12:28.560 Okay, let's get through this video and 00:12:26.399 --> 00:12:32.480 then I retire. Is reception an issue? Where did you put 00:12:30.399 --> 00:12:36.480 your antennas? Yeah. So the antennas are actually underneath the space between 00:12:34.720 --> 00:12:42.160 the battery and the palm rest. So there's metal in front of them. Yes. Ah 00:12:39.120 --> 00:12:44.160 but you know metal and air are just you 00:12:42.160 --> 00:12:49.519 know the difference of molecules right basically. I mean yeah. Are you sure you 00:12:48.000 --> 00:12:54.320 wouldn't have considered maybe you know running them up here like they do on 00:12:51.040 --> 00:12:57.360 other laptops? Yeah but I got lazy from 00:12:54.320 --> 00:12:59.519 my past having done 2.4 GHz and 5 GHz 00:12:57.360 --> 00:13:04.000 and RF engineering. It doesn't really matter if you're going through um metal 00:13:02.320 --> 00:13:08.800 that much. All right, let's see this display. Okay, man. This display looks 00:13:06.399 --> 00:13:12.320 incredible. Okay, so let's talk a little bit about that. Where on earth do you go 00:13:10.240 --> 00:13:16.160 about getting a 4K AMOLED panel if you need one? I was just looking through 00:13:14.000 --> 00:13:21.519 scrolling and I found this panel, the ATNA 33TP11 from Samsung. That's the 4K 00:13:19.519 --> 00:13:26.079 AMOLED display panel you see here. It was on some old ASUS laptops from 3 4 00:13:24.320 --> 00:13:30.880 years ago. And I really liked it cuz it looks so good and yeah, looks awesome. 00:13:28.320 --> 00:13:34.639 So, I bought some off of Tao or the Chinese AliExpress basically. And the 00:13:32.880 --> 00:13:39.120 hard part was running it directly from the RK3588 over embedded DisplayPort, 00:13:37.120 --> 00:13:43.440 right? Cuz here's the thing. Embedded DisplayPort theoretically is a 00:13:40.800 --> 00:13:50.240 standard, but everyone both on the system side and the panel side around 00:13:46.639 --> 00:13:54.120 with it. So, how did you get it working? 00:13:50.240 --> 00:13:56.560 Yeah. One sec. He's gone. He 00:13:54.120 --> 00:14:00.920 left. I mean, I broke his laptop. I guess I kind of had it coming. When I 00:13:58.320 --> 00:14:04.639 first started the project, I chose this RK3588 system on a module. Yeah. So, it 00:14:03.279 --> 00:14:08.079 slots into this development board just like that. You know, just pop it pops 00:14:06.320 --> 00:14:10.959 right in. Beautiful. This is that thing that we featured, the little NAS thing. 00:14:09.680 --> 00:14:14.240 It is. You were the one that inspired it. Oh. Oh, that's cool. Great. Nice 00:14:13.360 --> 00:14:18.880 little board. And, you know, you can make a laptop. Yeah, it's a really cool little board. We're probably going to 00:14:17.279 --> 00:14:21.320 have a Floatplane behind the scenes for this with some extras. So, uh check it 00:14:20.399 --> 00:14:26.560 out. lg.gg/flowplane. It's for the w What the 00:14:24.959 --> 00:14:31.120 Yeah. Sir, now when you talked about different 00:14:28.800 --> 00:14:35.600 pinouts, different protocols, OLED panels actually have a different pin out 00:14:32.720 --> 00:14:39.519 than LCDs. And since no one DIYs OLED panels, I had to reverse engineer them 00:14:37.120 --> 00:14:43.519 from a data dump on Linux from the Asus laptop that used to have them. So after 00:14:41.920 --> 00:14:46.720 doing some reverse engineering and maybe procuring a data sheet, this is the 00:14:45.199 --> 00:14:51.760 cable that is needed to drive the display. Very, very fine pitch 40 pin 00:14:49.279 --> 00:14:55.600 cable and it's impedance matched to the EDP specifications. And that's at least 00:14:53.920 --> 00:14:58.320 one thing that you know they go by somewhat. How do you source one of 00:14:57.199 --> 00:15:05.360 these? How do you know it's the right one? Yeah. So on Tao they actually sell 00:15:01.360 --> 00:15:07.360 um OLED EDP cables. And so I just bought 00:15:05.360 --> 00:15:10.480 one and pray that it works. Unfortunately it didn't really work 00:15:08.880 --> 00:15:14.399 because these cables actually convert from a standard LCD pin out to an OLED 00:15:13.279 --> 00:15:19.440 pin out which is not what I actually want. Oh cuz you want to go native. Yes. 00:15:16.560 --> 00:15:23.920 I want to go OLED to OLED. OLED. Yes. So then what did you have to do? So, what I 00:15:21.680 --> 00:15:26.639 did was I made two of these boards. They look wildly different from one another 00:15:25.440 --> 00:15:31.279 because one of them works and one of them doesn't. Can you guess which one works and which one doesn't, Lionus? I'm 00:15:29.839 --> 00:15:37.120 going to say this one works. How did you know? Because it's just simpler. He's 00:15:34.079 --> 00:15:38.720 right. He's right. So, actually, it 00:15:37.120 --> 00:15:42.320 came. Again, we've designed a couple products. RF engineering is kind of 00:15:40.560 --> 00:15:47.600 black magic. So, a lot of the signals you can't really probe. You just have to guess based on vibes. So, my guess was 00:15:45.600 --> 00:15:52.560 that this was just too much loss. And you know it looks really really cursed 00:15:49.199 --> 00:15:55.839 plug in its HDMI but actually the chips 00:15:52.560 --> 00:15:57.920 the chip the RK3588 itself convert uh 00:15:55.839 --> 00:16:02.320 has a multiplexer inside the chip that takes either HDMI or embedded display 00:16:00.240 --> 00:16:06.720 port and sends it out. Right. So what I actually did was I changed the Linux 00:16:03.759 --> 00:16:11.839 kernel driver or the device tree to output EDP off of this HDMI port 00:16:09.000 --> 00:16:17.759 instead. And um then you went straight into here. Boom. Yeah. And after a lot 00:16:15.199 --> 00:16:22.320 of kernel development and some device a lot of device redefinition development, 00:16:20.160 --> 00:16:26.959 it just works. Plug it in and it just works as a native display. Let's talk 00:16:24.079 --> 00:16:32.240 about the trackpad. This thing feels great. Yeah. Is this glass? It is glass. 00:16:29.600 --> 00:16:36.880 Glass topped. Man, everyone should just use a trackpad 00:16:35.120 --> 00:16:40.920 with a glass top like this. Sorry. What gesture did you want me to? If you do 00:16:38.720 --> 00:16:47.040 three finger like that, I got a Mac with Hey, look at that. 00:16:44.160 --> 00:16:52.160 Oh, I love it. Fun fact, by the way, Linux had that like a decade before 00:16:50.000 --> 00:16:56.800 anyone else did. I have a spare trackpad right here. It's a module from Aotech. A 00:16:54.720 --> 00:17:01.279 Zotch. A Zotch. So, they're an OEM trackpad manufacturer. I decided to just 00:16:58.560 --> 00:17:03.600 buy a module and modify it to fit within this laptop. They don't actually don't 00:17:02.720 --> 00:17:10.319 make it anymore. I think they were losing money selling them. So, it's too bad that they don't continue to sell 00:17:07.120 --> 00:17:12.079 them because for DIYers that dev kits 00:17:10.319 --> 00:17:16.480 can be an absolute lifesaver. I want to hear the speakers. Your speakers? Oh, 00:17:14.079 --> 00:17:21.679 they will shock you. What flavor of Linux are we on right now? Almost 00:17:18.240 --> 00:17:23.439 identical. Yeah. Also going to You know 00:17:21.679 --> 00:17:29.640 the crazy thing is if you press it down back lit and not full lit 00:17:27.480 --> 00:17:35.600 whereas I'm just lit. Why am I flat? I'm drinking. I 00:17:34.320 --> 00:17:39.120 I said I was going to blow you away, right? Yeah. You didn't say if it was 00:17:37.679 --> 00:17:43.600 going to be in a good way or a bad way. Well, I certainly can't call you a liar 00:17:40.960 --> 00:17:48.880 then. Now, I have a question for you. You obviously are using an ARMbased chip 00:17:45.840 --> 00:17:50.799 for cost and power efficiency reasons 00:17:48.880 --> 00:17:54.000 and also because there's no way Intel's going to send you, you know, the 00:17:52.480 --> 00:17:57.679 drawings that you would need to develop an Intelbased laptop or whatever. Did 00:17:56.240 --> 00:18:02.640 you really feel like that was that much of a compromise these days? I think with 00:18:00.160 --> 00:18:06.080 the RK 3588, it really wasn't that big of a compromise because you can do 00:18:04.240 --> 00:18:10.640 pretty much everything that you'd expect on a mid low-end laptop. Of course, you 00:18:09.280 --> 00:18:14.799 can't play, you know, Balders's Gate or something, but sure, you know, you can 00:18:12.400 --> 00:18:18.720 do, you know, regular everyday tasks on it, no problem. Theoretically, there is 00:18:16.720 --> 00:18:24.320 a project that's working on having Windows run on RK3588 based chips. But 00:18:22.240 --> 00:18:27.919 the development it requires to support custom hardware like mine where I made a 00:18:26.320 --> 00:18:31.679 motherboard and I made the power system and driving the display. It require a 00:18:29.919 --> 00:18:35.760 lot of work on to develop the firmware itself to boot the laptop and get it to 00:18:33.840 --> 00:18:40.880 a working state. That's super cool. I want to see Minecraft. 00:18:37.640 --> 00:18:43.840 So, you said 4K 60. I guess you meant 4K 00:18:40.880 --> 00:18:47.280 60 Hz, not 4K 60 frames per second. Well, you see, if you look down at the 00:18:44.880 --> 00:18:52.799 ground, you get 60 FPS. I see. Yeah. But, you know, it's 00:18:50.799 --> 00:18:56.480 playable. It's playable. Especially on Bedwars Hypixel where you're actually 00:18:54.400 --> 00:19:00.160 rendering a lot less than a world. You actually hit quite high frame rates. It 00:18:58.080 --> 00:19:05.039 looks great, right? It does. It does look great. There's no webcam. No. What 00:19:02.480 --> 00:19:08.880 was your reason though? Well, publicly, it's for 00:19:06.200 --> 00:19:11.919 privacy, but honestly, it's just so difficult to implement something so 00:19:10.320 --> 00:19:15.280 thin. I didn't have the time and the capability to fit in a full webcam and 00:19:13.520 --> 00:19:20.320 run it through the dis hard display. And it's easy to complain about webcams. 00:19:17.600 --> 00:19:26.080 It's really hard to make a better one. I am playing video games right now on this 00:19:22.559 --> 00:19:28.960 laptop which looks like a real laptop 00:19:26.080 --> 00:19:33.360 and obviously has some rough edges. Yep. It's falling apart a little. What would 00:19:30.960 --> 00:19:38.880 you say is your biggest specialty that helped you execute this? It's the making 00:19:35.679 --> 00:19:40.559 these circuit boards myself. Yeah. And 00:19:38.880 --> 00:19:46.880 you can see here he's got his own silk screening. This board here is clearly a 00:19:44.799 --> 00:19:51.360 lot smaller than the development board here. Got your own socketed M.2, your 00:19:49.200 --> 00:19:57.280 own socketed Wi-Fi module slot. The fact that this works is a small miracle. Are 00:19:55.280 --> 00:20:00.240 you doubting my skill, Lionus? Nope. I'm saying that the fact that your skill 00:19:58.559 --> 00:20:05.919 exists is a small miracle. Thank you. Thank you. I'm calling you a miracle. Take a compliment. Thank you, Lionus. I 00:20:03.200 --> 00:20:10.160 appreciate it. Wow. And that's it. Sorry. I have this one 00:20:07.600 --> 00:20:15.000 too. And then we just put the uh the rock chip, daughter board, brain board, 00:20:13.760 --> 00:20:23.280 whatever you want to call it, on on there. Boom. Just like that. 00:20:20.160 --> 00:20:26.720 This is outstanding. Like the density 00:20:23.280 --> 00:20:29.200 here. I would be impressed if I saw this 00:20:26.720 --> 00:20:34.880 on a professional product, let alone, no offense, but from like some kid. How 00:20:31.760 --> 00:20:37.280 many layers is this? Six layers. So I 00:20:34.880 --> 00:20:40.799 have the top and bottom layer for signal and power. The second two layers for 00:20:39.280 --> 00:20:47.440 impedance matching as a ground reference plane and the middle two layers as power 00:20:44.679 --> 00:20:52.799 rails. So every trace on the high-speed signaling like the USBC, USBA, SD card, 00:20:51.360 --> 00:20:55.919 they are all impedance match in particular the u uh embedded display 00:20:54.400 --> 00:20:59.200 port signaling. Everything in this region is impedance controlled and 00:20:57.440 --> 00:21:03.120 impedance calculated, simulated, all of that to make sure that the signals don't 00:21:01.200 --> 00:21:08.159 get interfered with on its way to whatever we need to do. And that stuff 00:21:04.320 --> 00:21:11.280 is a that stuff is a and a half. Like, 00:21:08.159 --> 00:21:13.520 wow. Now, the last question that I'm 00:21:11.280 --> 00:21:17.440 sure people are going to be asking is this project obviously raised your 00:21:15.280 --> 00:21:22.559 profile a fair bit. Have you gotten any interesting job offers? Yeah, I can't 00:21:19.679 --> 00:21:25.679 disclose much, but I did get uh more job offers than the number on my hands, 00:21:24.159 --> 00:21:29.679 which is great. I'm super grateful for that. Yeah. And I got to make a a video 00:21:28.000 --> 00:21:34.799 with you. Well, I mean, that's the best thing I got. Sure. 00:21:32.480 --> 00:21:39.280 Yeah. Yeah. The guys who work here can see how excited they are about it. Wow. 00:21:37.120 --> 00:21:44.159 Really? But I bet whoever gave them to him doesn't dance around topless like a 00:21:42.080 --> 00:21:48.880 firefighter. It's a little traumatizing. 00:21:47.039 --> 00:21:52.400 I can send you the design files for the circuit boards because a lot of people 00:21:50.400 --> 00:21:57.200 wonder how you make circuit boards like this. pretty much anyone can get a 00:21:54.559 --> 00:22:00.880 circuit board made. This cost $60. $60? Yeah. Like it is shockingly affordable. 00:21:59.679 --> 00:22:07.360 With this out of the way, what's your next big project? Yeah. So, I have two projects I'm trying I'm trying to get to 00:22:04.400 --> 00:22:10.559 right now. One is a super super light mouse that doesn't have a battery, and 00:22:09.520 --> 00:22:14.480 I'm going to leave it at that. It's going to be super light. There's no battery, but it's wireless. Okay. No 00:22:13.200 --> 00:22:19.440 spoilers. You'll have to subscribe to his channel. What's the other one? I hopefully in the future I'll get to 00:22:17.520 --> 00:22:24.080 making a second revision of the laptop. or I'm gonna have a better chip, better 00:22:21.360 --> 00:22:26.400 everything, and maybe maybe get to making some kits. Yeah, that would 00:22:25.280 --> 00:22:31.840 actually be really cool. I mean, you've open sourced all of this, right? That's right. Yeah. Uh everything you see on 00:22:29.760 --> 00:22:35.039 this table is completely open source on my GitHub. That's super cool. So, we're 00:22:33.840 --> 00:22:39.039 going to have that linked in the video description. I love this keyboard. The 00:22:36.880 --> 00:22:42.320 the keyboard, dude. I This is really cool. This is a really cool showcase 00:22:40.720 --> 00:22:47.600 piece. But you really like the keyboard, but this is this is this is a product. 00:22:44.240 --> 00:22:49.760 This is that that's that's very cool. 00:22:47.600 --> 00:22:53.760 Thank you. Yeah. And you know what else is cool? Firing Colton shouldn't be a 00:22:51.919 --> 00:22:58.240 joke. What we actually take to fire Colton. Okay, Dennis, we talk about this 00:22:56.240 --> 00:23:02.000 every month. ODO is sponsoring this video. Take this. All right, sit down. 00:23:00.240 --> 00:23:05.679 Let's talk. Let's check his attendance. We got to find something. Oh, man. He's 00:23:03.919 --> 00:23:09.039 actually been really reliable. Wait, what? And he's been doing all this OT. 00:23:07.840 --> 00:23:12.960 He might actually be working really hard. Dennis, showing up to work doesn't 00:23:10.960 --> 00:23:17.039 mean he's actually working. Yeah, that's true. Let's check his goals, then. 00:23:14.799 --> 00:23:20.880 Excuse me. He actually accomplished all of his goals. Dennis, you need to pay me 00:23:18.640 --> 00:23:25.679 more. Okay. What if he's been expenses his personal stuff as work? That can be 00:23:23.120 --> 00:23:32.159 a big problem. Oh, wow. He's expensed like $3,000 in March. What? Pizza party 00:23:28.880 --> 00:23:33.600 with friends for $900. That sounds very 00:23:32.159 --> 00:23:38.720 suspicious. Yeah, I didn't get invited to this party. Con, you're so fire. Con, 00:23:36.080 --> 00:23:43.840 you're fire. Happy birthday. Never mind. If you guys enjoyed this video, then you 00:23:40.799 --> 00:23:45.840 will enjoy Byron's deeper look, which as 00:23:43.840 --> 00:23:50.400 I admitted before, I have only skimmed. But now I get to watch fully. Um, and 00:23:48.880 --> 00:23:55.360 I'm really excited for that because he goes into a little bit more depth on 00:23:53.039 --> 00:23:59.280 some of the individual design choices as well as like the specs which we kind of 00:23:57.919 --> 00:24:02.960 glossed over here. So guys, you're going to want to check out his video. You're going to want to check out his GitHub. 00:24:01.840 --> 00:24:08.480 Is there anything else you want to shout out since you're here? Thank you to everyone for supporting me. Hi mom. 00:24:07.200 --> 00:24:11.960 Thank you for having me. Oh yeah, my pleasure, dude. Uh 00:24:12.240 --> 00:24:15.640 oh my god. 00:24:16.400 --> 00:24:20.320 Really nice to meet you, man. They see me less.
