1
00:00:00,480 --> 00:00:08,080
now this doesn't look very much like a macbook because

2
00:00:04,480 --> 00:00:10,400
it's actually the latte panda alpha but

3
00:00:08,080 --> 00:00:16,880
in terms of the actual hardware on this thing it is nearly identical to the 2015

4
00:00:14,400 --> 00:00:21,840
macbook so it's got a dual core Intel processor eight gigs of RAM and

5
00:00:19,760 --> 00:00:27,359
what's very interesting is that it has two pci express expansion slots on it so

6
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

7
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

8
00:00:36,640 --> 00:00:42,160
macbook bottleneck city here we come oh yeah

9
00:00:43,440 --> 00:00:48,879
oh speaking of bottlenecks this segway was bottlenecked by me not remembering

10
00:00:47,440 --> 00:00:53,120
who the sponsor is ruggable rugs are machine washable spill

11
00:00:51,200 --> 00:00:55,680
and stain resistant and they're non-toxic

12
00:00:54,559 --> 00:01:00,640
they're great for protecting your hardwood floors and with code fun Linus

13
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

14
00:01:02,239 --> 00:01:13,760
available in the us and canada

15
00:01:13,760 --> 00:01:19,600
now the latte panda alpha is more than just

16
00:01:17,360 --> 00:01:23,200
you know the original macbook on a single pcb here in fact it's not

17
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

18
00:01:25,840 --> 00:01:31,759
walk us through some of the things that make this particular device kind of

19
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

20
00:01:34,960 --> 00:01:42,880
right here along with rs there's a 232 and just a bunch of

21
00:01:40,079 --> 00:01:48,240
general input output stuff so what this is is effectively like the same kind of

22
00:01:46,159 --> 00:01:53,840
computer as uh something like a raspberry pi where everything is very

23
00:01:51,119 --> 00:01:58,000
very embedded so there's your micro st expansion there's your display output

24
00:01:56,079 --> 00:02:04,000
with a little nice little ribbon cable there and all that good stuff except it

25
00:02:00,479 --> 00:02:07,920
is way more powerful so this thing runs

26
00:02:04,000 --> 00:02:10,160
a core m3 7y30 CPU like i said before

27
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

28
00:02:12,640 --> 00:02:17,920
to be using today the dual m.2 adapters

29
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

30
00:02:19,760 --> 00:02:28,000
Intel wireless over here nice got that rj45 Ethernet this HDMI port can do up

31
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

32
00:02:30,080 --> 00:02:36,480
c and over on the other side three usb 3

33
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

34
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

35
00:02:43,599 --> 00:02:51,480
test bench here shall we yeah sounds good to me

36
00:02:47,599 --> 00:02:51,480
what what you doing

37
00:02:53,760 --> 00:03:01,280
yes we have the same shirt on do do we want to address that or just

38
00:02:58,720 --> 00:03:04,280
keep going lttstore.com

39
00:03:04,879 --> 00:03:12,800
that's the good stuff right there literally costs more than 2x the entire

40
00:03:10,239 --> 00:03:16,959
rest of the computer literally so

41
00:03:14,560 --> 00:03:23,920
let's see here this is my old nemesis

42
00:03:19,200 --> 00:03:25,280
the exp gdc beast that thing's back yeah

43
00:03:23,920 --> 00:03:29,519
this thing's back we had so much trouble with this thing

44
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

45
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

46
00:03:37,280 --> 00:03:44,879
crap so depending on what laptop you put it in and how long the traces are

47
00:03:41,360 --> 00:03:46,879
between the m.2 key and the CPU it can

48
00:03:44,879 --> 00:03:52,239
just not work sometimes for no reason okay so we want to use our

49
00:03:49,760 --> 00:03:56,080
m.2 key m for our graphics card is that correct

50
00:03:54,000 --> 00:03:59,840
yeah and so this is where the keen among you have probably

51
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

52
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

53
00:04:09,200 --> 00:04:16,479
anything that you would want to put in there basically you can't the main

54
00:04:13,280 --> 00:04:19,040
difference between a key m and a key e

55
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

56
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

57
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

58
00:04:30,479 --> 00:04:40,320
here now key m is intended for things like NVMe storage and in this case

59
00:04:37,040 --> 00:04:42,880
our adapter to this pci express 16x slot

60
00:04:40,320 --> 00:04:48,000
which should theoretically now have a 4x worth of bandwidth

61
00:04:44,400 --> 00:04:49,919
key e is generally used for like wi-fi

62
00:04:48,000 --> 00:04:54,479
cards so obviously we're not going to have any storage

63
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

64
00:04:56,800 --> 00:05:02,160
storage on the latte panda but that's enough not enough for like a game or

65
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

66
00:05:04,639 --> 00:05:10,240
library off that that would been slow no that would have been perfectly fast

67
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

68
00:05:13,199 --> 00:05:19,600
has storage on it well speaking of waiting around we had

69
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

70
00:05:21,440 --> 00:05:26,400
adapter to pci slot thing yeah you use

71
00:05:24,960 --> 00:05:30,080
that use this guy right here plug it in like

72
00:05:28,800 --> 00:05:36,639
so you'd think it would work but it just doesn't

73
00:05:33,440 --> 00:05:39,840
okay cool which is why we need

74
00:05:36,639 --> 00:05:39,840
this right here

75
00:05:40,160 --> 00:05:45,919
did you just like stash pieces of this project all over the room

76
00:05:44,400 --> 00:05:50,720
yes all right so this is from syntek

77
00:05:48,639 --> 00:05:54,320
electronic co-limited and it appears to be

78
00:05:52,400 --> 00:05:57,680
an e key to

79
00:05:55,440 --> 00:06:01,520
m key adapter this is definitely increasing the bulk of our solution a

80
00:05:59,520 --> 00:06:06,720
little bit but if it works then i'll be i'll be pretty pleased

81
00:06:03,680 --> 00:06:08,960
curiously even though latte panda has a

82
00:06:06,720 --> 00:06:13,039
key e here which normally is actually used with short cards like this one they

83
00:06:11,360 --> 00:06:16,160
don't actually have like a mounting spot for it they've got an 80 millimeter

84
00:06:14,639 --> 00:06:20,479
mounting spot just like if you were to plug in an SSD what were they thinking

85
00:06:18,400 --> 00:06:25,039
um i just turned it over and figured that gravity would keep it in

86
00:06:22,880 --> 00:06:27,919
good guy gravity all right so now that we've got our

87
00:06:26,080 --> 00:06:33,479
single board computer our unnecessary storage and our pci express slot all

88
00:06:30,319 --> 00:06:36,720
that we need to do now is plug in our

89
00:06:33,479 --> 00:06:38,880
330 watt power brick to the beast here

90
00:06:36,720 --> 00:06:42,400
look at this thing it's awesome so then we get power for

91
00:06:41,520 --> 00:06:46,880
our car have you noticed a problem here yeah we

92
00:06:45,039 --> 00:06:49,919
need two eight pins yeah let me guess you stashed it in a drawer

93
00:06:48,800 --> 00:06:57,840
somewhere oh do you want to know where it is can you find it okay um

94
00:06:54,720 --> 00:06:57,840
not in the banana cup

95
00:06:58,319 --> 00:07:00,960
not in there

96
00:07:01,360 --> 00:07:07,280
no you're like way off

97
00:07:05,280 --> 00:07:11,599
we can play hot and cold if you want you're getting hotter much hotter

98
00:07:09,680 --> 00:07:15,440
and a bit hotter you know you're getting colder now

99
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

100
00:07:18,960 --> 00:07:24,080
that's no you're you're colder now

101
00:07:22,800 --> 00:07:28,800
do you want me to just get it for you this is painful yeah

102
00:07:26,880 --> 00:07:31,840
oh we need a second yeah we have a whole power supply

103
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

104
00:07:37,360 --> 00:07:45,120
board computer with the e key to m key adapter for the

105
00:07:41,440 --> 00:07:48,479
unnecessary storage we've got the m-key

106
00:07:45,120 --> 00:07:49,759
2 pci express slot adapter for our titan

107
00:07:48,479 --> 00:07:56,000
rtx now the beast down here is powered by

108
00:07:52,960 --> 00:07:57,759
this dell power brick and then the plugs

109
00:07:56,000 --> 00:08:03,280
at the top of the card are handled by this seasonic prime gold power supply

110
00:08:00,639 --> 00:08:06,639
850 watts now we can turn it on well that's not plugged in but

111
00:08:04,960 --> 00:08:10,800
other than that yeah type c power and i'm assuming this is

112
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

113
00:08:14,479 --> 00:08:20,800
gaming yeah you know what i don't see anything wrong in the menus so far

114
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

115
00:08:23,440 --> 00:08:29,759
the uh the fan's definitely ramping up though yeah so you might have noticed

116
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

117
00:08:32,640 --> 00:08:39,120
times are absolutely atrocious so we're supposed to play

118
00:08:37,039 --> 00:08:42,560
games while we wait for our video games yeah there's no point in like just

119
00:08:40,560 --> 00:08:45,760
sitting in front of it like now my understanding is you're actually pretty

120
00:08:43,839 --> 00:08:48,640
good at ping pong i'm like not bad

121
00:08:50,240 --> 00:08:53,800
oh nice shot

122
00:08:54,080 --> 00:08:56,399
ah

123
00:09:00,800 --> 00:09:07,120
oh it's loaded now that's actually not that bad yeah

124
00:09:04,959 --> 00:09:13,680
it's not great i was running these settings on an rtx 2080 mobile with a

125
00:09:11,120 --> 00:09:17,360
mobile core i9 and i was getting about anywhere from double to triple that this

126
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

127
00:09:19,200 --> 00:09:25,680
bit better the part that i'm more concerned about is you can see some real

128
00:09:22,560 --> 00:09:28,800
stutters like that

129
00:09:25,680 --> 00:09:32,160
like it says 50 but it's like

130
00:09:28,800 --> 00:09:33,360
the frame times are not

131
00:09:32,160 --> 00:09:37,920
necessarily keeping up here yeah it gets pretty hot

132
00:09:35,839 --> 00:09:42,080
yeah it actually smells hot you know like the smell of hot electronics

133
00:09:41,040 --> 00:09:44,880
not really so technically we got a benchmark score

134
00:09:44,080 --> 00:09:51,839
there uh but i get the feeling that this is kind of where the system

135
00:09:49,760 --> 00:09:57,120
wasn't running properly okay we're going to call that a fail

136
00:09:54,080 --> 00:09:58,560
oh wow our CPU was pinned at 100 the

137
00:09:57,120 --> 00:10:03,760
whole time yeah holy banana sacks okay you want to

138
00:10:01,519 --> 00:10:06,480
go ahead and fire up game number two all right well we have city skylines

139
00:10:05,360 --> 00:10:11,839
here this is a trip this is even more CPU

140
00:10:09,279 --> 00:10:14,079
intensive yeah also RAM what are you trying to do to this poor

141
00:10:13,279 --> 00:10:19,519
thing we're pushing its limits you could say

142
00:10:17,519 --> 00:10:24,240
cities on the brink of bankruptcy except the bailout i just reject it reject the

143
00:10:21,360 --> 00:10:26,880
bailout yeah we're already 34 million dollars in the hole so

144
00:10:25,839 --> 00:10:32,959
i don't think there's much coming back wow this is running at crud-tastic

145
00:10:29,519 --> 00:10:38,000
details how's it doing about the same as

146
00:10:32,959 --> 00:10:39,040
before looks like about 10 FPS 15 FPS

147
00:10:38,000 --> 00:10:44,160
that might have been no it might have been more like 18 or so

148
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

149
00:10:46,240 --> 00:10:50,800
yeah it's not a great experience no

150
00:10:49,440 --> 00:10:54,160
we're definitely not getting the most out of our titan rtx time for our last

151
00:10:53,360 --> 00:11:00,760
game the appropriately named doom oh yeah we can probably play ping pong

152
00:11:04,640 --> 00:11:06,880
no

153
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

154
00:11:10,800 --> 00:11:16,640
just got to the main screen wow that was just launching the game

155
00:11:14,640 --> 00:11:21,440
that's fantastic okay so we're vulcan ultra 1440p hey

156
00:11:19,760 --> 00:11:27,519
that looks better this is actually not that bad

157
00:11:25,839 --> 00:11:31,440
now it's not great to be clear

158
00:11:29,360 --> 00:11:36,880
and you can also really see like the gpus serving frames about every three to

159
00:11:34,000 --> 00:11:41,040
four milliseconds and the CPU is taking about every

160
00:11:38,480 --> 00:11:46,720
20 or so so that is what is known as a severe CPU

161
00:11:44,800 --> 00:11:50,880
yeah i'm pretty confident that if we put like

162
00:11:48,959 --> 00:11:53,360
a 1060 into this the performance is going to be exactly

163
00:11:52,160 --> 00:12:00,240
the same low ammo yes glory killed

164
00:11:56,640 --> 00:12:02,000
like this is actually quite playable

165
00:12:00,240 --> 00:12:05,279
so given how bottlenecked we are i guess that's the point of this then

166
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

167
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

168
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

169
00:12:16,880 --> 00:12:19,440
about the same

170
00:12:21,120 --> 00:12:26,720
okay and that's it fire it up yeah

171
00:12:25,120 --> 00:12:31,279
i mean it's now a good opportunity to talk about what this is actually for

172
00:12:29,040 --> 00:12:35,200
sure i made this because it's the first

173
00:12:33,200 --> 00:12:38,079
sensor that i could find there we go

174
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

175
00:12:40,560 --> 00:12:47,839
have you had to eat today uh i had a subway sandwich and a

176
00:12:45,600 --> 00:12:52,160
crepe this morning hmm so i have built a fart detector

177
00:12:50,320 --> 00:12:57,600
so this light right here turns on when this detects methane gas fascinating

178
00:12:55,839 --> 00:13:02,800
so is the main benefit of this then that you can program your arduino on the

179
00:13:00,079 --> 00:13:05,519
machine that also contains your arduino yeah and i think it would be really

180
00:13:03,839 --> 00:13:09,120
useful if you're doing like iot stuff and you just had your arduino

181
00:13:07,360 --> 00:13:11,760
like stuffed behind a mirror or something in your house and you could

182
00:13:10,639 --> 00:13:16,320
just have Ethernet going to it and then you could

183
00:13:14,240 --> 00:13:20,639
change everything right on your little computer from far away now the intent

184
00:13:18,560 --> 00:13:24,560
was to use this in the bathroom right but it's not sensitive enough

185
00:13:22,560 --> 00:13:28,959
yeah so we wanted to make the bathroom that never smells so instead of turning

186
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

187
00:13:30,399 --> 00:13:35,360
turn the fans on so you'd know like someone really dropped a bomb in there

188
00:13:34,560 --> 00:13:41,760
yeah but the problem is that methane only about 50 of people really produce it

189
00:13:39,839 --> 00:13:45,120
when they flatulate so you want what is it

190
00:13:43,839 --> 00:13:50,560
um dihydrogen oxide or dihydrogen sulfide

191
00:13:49,120 --> 00:13:55,440
there we go which it turns out is really hard to get

192
00:13:52,880 --> 00:13:58,240
sensitive sensors for got it that are like cheap so it would have

193
00:13:56,720 --> 00:14:03,839
been like two grand or something dumb like that

194
00:14:00,240 --> 00:14:04,639
is that worth it i don't know maybe

195
00:14:03,839 --> 00:14:10,560
like i have definitely like walked into the bathroom and it's some unfortunate times

196
00:14:08,079 --> 00:14:16,959
recently so and there we are we're running at

197
00:14:12,959 --> 00:14:19,040
anywhere from 50 to 60 frames per second

198
00:14:16,959 --> 00:14:22,399
exactly the same as we were on the rtx titan

199
00:14:20,720 --> 00:14:26,959
that's pretty brutal so that my friends is what a CPU

200
00:14:24,800 --> 00:14:32,079
bottleneck looks like you install a graphics card that's

201
00:14:28,839 --> 00:14:34,800
literally half the performance and you

202
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

203
00:14:36,959 --> 00:14:44,000
that blue light is it weird to message the group chat if

204
00:14:41,120 --> 00:14:47,040
anyone like has gas today yes

205
00:14:45,839 --> 00:14:51,600
but i think that if you acknowledge that it's weird it's fine okay

206
00:14:49,279 --> 00:14:55,440
all right well no one heated our call so it also detects propane and butane so

207
00:14:53,600 --> 00:15:01,680
we're just gonna blow some gas at it so if you guys are

208
00:14:58,880 --> 00:15:05,199
into this kind of like uh iot maker stuff we actually have a really cool

209
00:15:02,800 --> 00:15:10,480
video coming on pie hole which is a way of using a raspberry pi as

210
00:15:07,839 --> 00:15:13,839
