WEBVTT 00:00:00.480 --> 00:00:08.080 now this doesn't look very much like a macbook because 00:00:04.480 --> 00:00:10.400 it's actually the latte panda alpha but 00:00:08.080 --> 00:00:16.880 in terms of the actual hardware on this thing it is nearly identical to the 2015 00:00:14.400 --> 00:00:21.840 macbook so it's got a dual core Intel processor eight gigs of RAM and 00:00:19.760 --> 00:00:27.359 what's very interesting is that it has two pci express expansion slots on it so 00:00:25.920 --> 00:00:32.559 we're going to be using one of those for storage and the other to simulate what 00:00:30.240 --> 00:00:39.360 it would be like if you could hook a titan rtx graphics card up to a 2015 00:00:36.640 --> 00:00:42.160 macbook bottleneck city here we come oh yeah 00:00:43.440 --> 00:00:48.879 oh speaking of bottlenecks this segway was bottlenecked by me not remembering 00:00:47.440 --> 00:00:53.120 who the sponsor is ruggable rugs are machine washable spill 00:00:51.200 --> 00:00:55.680 and stain resistant and they're non-toxic 00:00:54.559 --> 00:01:00.640 they're great for protecting your hardwood floors and with code fun Linus 00:00:58.160 --> 00:01:05.780 15 you can get 15 off your order and free shipping at the link below they're 00:01:02.239 --> 00:01:13.760 available in the us and canada 00:01:13.760 --> 00:01:19.600 now the latte panda alpha is more than just 00:01:17.360 --> 00:01:23.200 you know the original macbook on a single pcb here in fact it's not 00:01:21.920 --> 00:01:27.600 intended for what we're going to be using it for today at all do you want to 00:01:25.840 --> 00:01:31.759 walk us through some of the things that make this particular device kind of 00:01:30.400 --> 00:01:37.360 special here i don't know i guess there's only really two things it's really small and there's an arduino 00:01:34.960 --> 00:01:42.880 right here along with rs there's a 232 and just a bunch of 00:01:40.079 --> 00:01:48.240 general input output stuff so what this is is effectively like the same kind of 00:01:46.159 --> 00:01:53.840 computer as uh something like a raspberry pi where everything is very 00:01:51.119 --> 00:01:58.000 very embedded so there's your micro st expansion there's your display output 00:01:56.079 --> 00:02:04.000 with a little nice little ribbon cable there and all that good stuff except it 00:02:00.479 --> 00:02:07.920 is way more powerful so this thing runs 00:02:04.000 --> 00:02:10.160 a core m3 7y30 CPU like i said before 00:02:07.920 --> 00:02:16.640 eight gigs of RAM and there it is on the back the magic special sauce we're going 00:02:12.640 --> 00:02:17.920 to be using today the dual m.2 adapters 00:02:16.640 --> 00:02:22.480 in terms of the rest of the i o we've got touch interface for the display 00:02:19.760 --> 00:02:28.000 Intel wireless over here nice got that rj45 Ethernet this HDMI port can do up 00:02:25.360 --> 00:02:33.920 to 4k 60 which is really nice to see we've also got a headphone jack usb type 00:02:30.080 --> 00:02:36.480 c and over on the other side three usb 3 00:02:33.920 --> 00:02:41.200 type a's cooling is taken care of by this heatsink fan up here and that's 00:02:38.319 --> 00:02:45.360 pretty much it so we can go ahead and uh get this thing set up on our box 00:02:43.599 --> 00:02:51.480 test bench here shall we yeah sounds good to me 00:02:47.599 --> 00:02:51.480 what what you doing 00:02:53.760 --> 00:03:01.280 yes we have the same shirt on do do we want to address that or just 00:02:58.720 --> 00:03:04.280 keep going lttstore.com 00:03:04.879 --> 00:03:12.800 that's the good stuff right there literally costs more than 2x the entire 00:03:10.239 --> 00:03:16.959 rest of the computer literally so 00:03:14.560 --> 00:03:23.920 let's see here this is my old nemesis 00:03:19.200 --> 00:03:25.280 the exp gdc beast that thing's back yeah 00:03:23.920 --> 00:03:29.519 this thing's back we had so much trouble with this thing 00:03:28.000 --> 00:03:34.799 the first time we tried to do a project with it and by we i mean alex 00:03:32.400 --> 00:03:39.519 yeah it turns out that although it uses an m.2 adapter the signal is kind of 00:03:37.280 --> 00:03:44.879 crap so depending on what laptop you put it in and how long the traces are 00:03:41.360 --> 00:03:46.879 between the m.2 key and the CPU it can 00:03:44.879 --> 00:03:52.239 just not work sometimes for no reason okay so we want to use our 00:03:49.760 --> 00:03:56.080 m.2 key m for our graphics card is that correct 00:03:54.000 --> 00:03:59.840 yeah and so this is where the keen among you have probably 00:03:57.680 --> 00:04:05.280 realized that we have a bit of an issue because that is not an m.2 key or it is 00:04:02.560 --> 00:04:10.879 an m.2 key yeah but it's not an m it's not an m key yeah it's a m.2 key e so 00:04:09.200 --> 00:04:16.479 anything that you would want to put in there basically you can't the main 00:04:13.280 --> 00:04:19.040 difference between a key m and a key e 00:04:16.479 --> 00:04:22.960 m.2 is actually the number of well aside from the number of pci express lanes the 00:04:20.959 --> 00:04:27.600 position of the notch so there's a notch right here to ensure that you don't plug 00:04:24.880 --> 00:04:33.440 the wrong thing into the wrong slot and the key e ah so the notch is way over 00:04:30.479 --> 00:04:40.320 here now key m is intended for things like NVMe storage and in this case 00:04:37.040 --> 00:04:42.880 our adapter to this pci express 16x slot 00:04:40.320 --> 00:04:48.000 which should theoretically now have a 4x worth of bandwidth 00:04:44.400 --> 00:04:49.919 key e is generally used for like wi-fi 00:04:48.000 --> 00:04:54.479 cards so obviously we're not going to have any storage 00:04:52.000 --> 00:04:59.520 if we don't find a way to put an SSD in here there actually are 32 gigabytes of 00:04:56.800 --> 00:05:02.160 storage on the latte panda but that's enough not enough for like a game or 00:05:00.880 --> 00:05:07.039 anything so oh well we could have just plugged an external drive in and ran our steam 00:05:04.639 --> 00:05:10.240 library off that that would been slow no that would have been perfectly fast 00:05:09.039 --> 00:05:15.919 you mean we waited around for this adapter for nothing i didn't know it had storage on it it 00:05:13.199 --> 00:05:19.600 has storage on it well speaking of waiting around we had 00:05:17.840 --> 00:05:24.960 to wait around because like you'd think that this would work it's a wi-fi 00:05:21.440 --> 00:05:26.400 adapter to pci slot thing yeah you use 00:05:24.960 --> 00:05:30.080 that use this guy right here plug it in like 00:05:28.800 --> 00:05:36.639 so you'd think it would work but it just doesn't 00:05:33.440 --> 00:05:39.840 okay cool which is why we need 00:05:36.639 --> 00:05:39.840 this right here 00:05:40.160 --> 00:05:45.919 did you just like stash pieces of this project all over the room 00:05:44.400 --> 00:05:50.720 yes all right so this is from syntek 00:05:48.639 --> 00:05:54.320 electronic co-limited and it appears to be 00:05:52.400 --> 00:05:57.680 an e key to 00:05:55.440 --> 00:06:01.520 m key adapter this is definitely increasing the bulk of our solution a 00:05:59.520 --> 00:06:06.720 little bit but if it works then i'll be i'll be pretty pleased 00:06:03.680 --> 00:06:08.960 curiously even though latte panda has a 00:06:06.720 --> 00:06:13.039 key e here which normally is actually used with short cards like this one they 00:06:11.360 --> 00:06:16.160 don't actually have like a mounting spot for it they've got an 80 millimeter 00:06:14.639 --> 00:06:20.479 mounting spot just like if you were to plug in an SSD what were they thinking 00:06:18.400 --> 00:06:25.039 um i just turned it over and figured that gravity would keep it in 00:06:22.880 --> 00:06:27.919 good guy gravity all right so now that we've got our 00:06:26.080 --> 00:06:33.479 single board computer our unnecessary storage and our pci express slot all 00:06:30.319 --> 00:06:36.720 that we need to do now is plug in our 00:06:33.479 --> 00:06:38.880 330 watt power brick to the beast here 00:06:36.720 --> 00:06:42.400 look at this thing it's awesome so then we get power for 00:06:41.520 --> 00:06:46.880 our car have you noticed a problem here yeah we 00:06:45.039 --> 00:06:49.919 need two eight pins yeah let me guess you stashed it in a drawer 00:06:48.800 --> 00:06:57.840 somewhere oh do you want to know where it is can you find it okay um 00:06:54.720 --> 00:06:57.840 not in the banana cup 00:06:58.319 --> 00:07:00.960 not in there 00:07:01.360 --> 00:07:07.280 no you're like way off 00:07:05.280 --> 00:07:11.599 we can play hot and cold if you want you're getting hotter much hotter 00:07:09.680 --> 00:07:15.440 and a bit hotter you know you're getting colder now 00:07:13.440 --> 00:07:22.800 you're getting colder in your pocket no it's not okay you're like pretty close 00:07:18.960 --> 00:07:24.080 that's no you're you're colder now 00:07:22.800 --> 00:07:28.800 do you want me to just get it for you this is painful yeah 00:07:26.880 --> 00:07:31.840 oh we need a second yeah we have a whole power supply 00:07:32.960 --> 00:07:39.280 so then can i summarize for the people at home now yep we've got the single 00:07:37.360 --> 00:07:45.120 board computer with the e key to m key adapter for the 00:07:41.440 --> 00:07:48.479 unnecessary storage we've got the m-key 00:07:45.120 --> 00:07:49.759 2 pci express slot adapter for our titan 00:07:48.479 --> 00:07:56.000 rtx now the beast down here is powered by 00:07:52.960 --> 00:07:57.759 this dell power brick and then the plugs 00:07:56.000 --> 00:08:03.280 at the top of the card are handled by this seasonic prime gold power supply 00:08:00.639 --> 00:08:06.639 850 watts now we can turn it on well that's not plugged in but 00:08:04.960 --> 00:08:10.800 other than that yeah type c power and i'm assuming this is 00:08:08.800 --> 00:08:16.800 the power button here yep hey there we go nice okay so now it's just time for 00:08:14.479 --> 00:08:20.800 gaming yeah you know what i don't see anything wrong in the menus so far 00:08:19.120 --> 00:08:25.520 yeah it's going not bad everything here seems fine i'll just hit r and go 00:08:23.440 --> 00:08:29.759 the uh the fan's definitely ramping up though yeah so you might have noticed 00:08:27.360 --> 00:08:35.279 that we have a ping pong table over here yeah i did uh that's because the loading 00:08:32.640 --> 00:08:39.120 times are absolutely atrocious so we're supposed to play 00:08:37.039 --> 00:08:42.560 games while we wait for our video games yeah there's no point in like just 00:08:40.560 --> 00:08:45.760 sitting in front of it like now my understanding is you're actually pretty 00:08:43.839 --> 00:08:48.640 good at ping pong i'm like not bad 00:08:50.240 --> 00:08:53.800 oh nice shot 00:08:54.080 --> 00:08:56.399 ah 00:09:00.800 --> 00:09:07.120 oh it's loaded now that's actually not that bad yeah 00:09:04.959 --> 00:09:13.680 it's not great i was running these settings on an rtx 2080 mobile with a 00:09:11.120 --> 00:09:17.360 mobile core i9 and i was getting about anywhere from double to triple that this 00:09:15.680 --> 00:09:20.959 part's not bad with fewer people in the scene it's actually keeping up a little 00:09:19.200 --> 00:09:25.680 bit better the part that i'm more concerned about is you can see some real 00:09:22.560 --> 00:09:28.800 stutters like that 00:09:25.680 --> 00:09:32.160 like it says 50 but it's like 00:09:28.800 --> 00:09:33.360 the frame times are not 00:09:32.160 --> 00:09:37.920 necessarily keeping up here yeah it gets pretty hot 00:09:35.839 --> 00:09:42.080 yeah it actually smells hot you know like the smell of hot electronics 00:09:41.040 --> 00:09:44.880 not really so technically we got a benchmark score 00:09:44.080 --> 00:09:51.839 there uh but i get the feeling that this is kind of where the system 00:09:49.760 --> 00:09:57.120 wasn't running properly okay we're going to call that a fail 00:09:54.080 --> 00:09:58.560 oh wow our CPU was pinned at 100 the 00:09:57.120 --> 00:10:03.760 whole time yeah holy banana sacks okay you want to 00:10:01.519 --> 00:10:06.480 go ahead and fire up game number two all right well we have city skylines 00:10:05.360 --> 00:10:11.839 here this is a trip this is even more CPU 00:10:09.279 --> 00:10:14.079 intensive yeah also RAM what are you trying to do to this poor 00:10:13.279 --> 00:10:19.519 thing we're pushing its limits you could say 00:10:17.519 --> 00:10:24.240 cities on the brink of bankruptcy except the bailout i just reject it reject the 00:10:21.360 --> 00:10:26.880 bailout yeah we're already 34 million dollars in the hole so 00:10:25.839 --> 00:10:32.959 i don't think there's much coming back wow this is running at crud-tastic 00:10:29.519 --> 00:10:38.000 details how's it doing about the same as 00:10:32.959 --> 00:10:39.040 before looks like about 10 FPS 15 FPS 00:10:38.000 --> 00:10:44.160 that might have been no it might have been more like 18 or so 00:10:41.279 --> 00:10:49.440 yeah i've seen worse but like it works yeah it does work you could play this 00:10:46.240 --> 00:10:50.800 yeah it's not a great experience no 00:10:49.440 --> 00:10:54.160 we're definitely not getting the most out of our titan rtx time for our last 00:10:53.360 --> 00:11:00.760 game the appropriately named doom oh yeah we can probably play ping pong 00:11:04.640 --> 00:11:06.880 no 00:11:07.680 --> 00:11:12.640 i'm trying to snipe the corner there i think it's my serve well actually we 00:11:10.800 --> 00:11:16.640 just got to the main screen wow that was just launching the game 00:11:14.640 --> 00:11:21.440 that's fantastic okay so we're vulcan ultra 1440p hey 00:11:19.760 --> 00:11:27.519 that looks better this is actually not that bad 00:11:25.839 --> 00:11:31.440 now it's not great to be clear 00:11:29.360 --> 00:11:36.880 and you can also really see like the gpus serving frames about every three to 00:11:34.000 --> 00:11:41.040 four milliseconds and the CPU is taking about every 00:11:38.480 --> 00:11:46.720 20 or so so that is what is known as a severe CPU 00:11:44.800 --> 00:11:50.880 yeah i'm pretty confident that if we put like 00:11:48.959 --> 00:11:53.360 a 1060 into this the performance is going to be exactly 00:11:52.160 --> 00:12:00.240 the same low ammo yes glory killed 00:11:56.640 --> 00:12:02.000 like this is actually quite playable 00:12:00.240 --> 00:12:05.279 so given how bottlenecked we are i guess that's the point of this then 00:12:04.160 --> 00:12:11.200 yeah i'm very confident that we'll get the same performance with a 1060 as we did 00:12:09.360 --> 00:12:14.880 with the titan so we were looking at about 50 to 60 frames per second in that 00:12:13.360 --> 00:12:19.440 level of doom so why don't we fire it up with a gtx 1060 and see if we're looking 00:12:16.880 --> 00:12:19.440 about the same 00:12:21.120 --> 00:12:26.720 okay and that's it fire it up yeah 00:12:25.120 --> 00:12:31.279 i mean it's now a good opportunity to talk about what this is actually for 00:12:29.040 --> 00:12:35.200 sure i made this because it's the first 00:12:33.200 --> 00:12:38.079 sensor that i could find there we go 00:12:36.800 --> 00:12:43.440 and i think it's just running right now so going back to what i said earlier what 00:12:40.560 --> 00:12:47.839 have you had to eat today uh i had a subway sandwich and a 00:12:45.600 --> 00:12:52.160 crepe this morning hmm so i have built a fart detector 00:12:50.320 --> 00:12:57.600 so this light right here turns on when this detects methane gas fascinating 00:12:55.839 --> 00:13:02.800 so is the main benefit of this then that you can program your arduino on the 00:13:00.079 --> 00:13:05.519 machine that also contains your arduino yeah and i think it would be really 00:13:03.839 --> 00:13:09.120 useful if you're doing like iot stuff and you just had your arduino 00:13:07.360 --> 00:13:11.760 like stuffed behind a mirror or something in your house and you could 00:13:10.639 --> 00:13:16.320 just have Ethernet going to it and then you could 00:13:14.240 --> 00:13:20.639 change everything right on your little computer from far away now the intent 00:13:18.560 --> 00:13:24.560 was to use this in the bathroom right but it's not sensitive enough 00:13:22.560 --> 00:13:28.959 yeah so we wanted to make the bathroom that never smells so instead of turning 00:13:26.959 --> 00:13:32.639 a light on like on a breadboard it would turn it on outside of the bathroom and 00:13:30.399 --> 00:13:35.360 turn the fans on so you'd know like someone really dropped a bomb in there 00:13:34.560 --> 00:13:41.760 yeah but the problem is that methane only about 50 of people really produce it 00:13:39.839 --> 00:13:45.120 when they flatulate so you want what is it 00:13:43.839 --> 00:13:50.560 um dihydrogen oxide or dihydrogen sulfide 00:13:49.120 --> 00:13:55.440 there we go which it turns out is really hard to get 00:13:52.880 --> 00:13:58.240 sensitive sensors for got it that are like cheap so it would have 00:13:56.720 --> 00:14:03.839 been like two grand or something dumb like that 00:14:00.240 --> 00:14:04.639 is that worth it i don't know maybe 00:14:03.839 --> 00:14:10.560 like i have definitely like walked into the bathroom and it's some unfortunate times 00:14:08.079 --> 00:14:16.959 recently so and there we are we're running at 00:14:12.959 --> 00:14:19.040 anywhere from 50 to 60 frames per second 00:14:16.959 --> 00:14:22.399 exactly the same as we were on the rtx titan 00:14:20.720 --> 00:14:26.959 that's pretty brutal so that my friends is what a CPU 00:14:24.800 --> 00:14:32.079 bottleneck looks like you install a graphics card that's 00:14:28.839 --> 00:14:34.800 literally half the performance and you 00:14:32.079 --> 00:14:39.440 get zero change in FPS so all that's left for this video then is to light up 00:14:36.959 --> 00:14:44.000 that blue light is it weird to message the group chat if 00:14:41.120 --> 00:14:47.040 anyone like has gas today yes 00:14:45.839 --> 00:14:51.600 but i think that if you acknowledge that it's weird it's fine okay 00:14:49.279 --> 00:14:55.440 all right well no one heated our call so it also detects propane and butane so 00:14:53.600 --> 00:15:01.680 we're just gonna blow some gas at it so if you guys are 00:14:58.880 --> 00:15:05.199 into this kind of like uh iot maker stuff we actually have a really cool 00:15:02.800 --> 00:15:10.480 video coming on pie hole which is a way of using a raspberry pi as 00:15:07.839 --> 00:15:13.839 a better than a
