now this doesn't look very much like a macbook because
it's actually the latte panda alpha but
in terms of the actual hardware on this thing it is nearly identical to the 2015
macbook so it's got a dual core Intel processor eight gigs of RAM and
what's very interesting is that it has two pci express expansion slots on it so
we're going to be using one of those for storage and the other to simulate what
it would be like if you could hook a titan rtx graphics card up to a 2015
macbook bottleneck city here we come oh yeah
oh speaking of bottlenecks this segway was bottlenecked by me not remembering
who the sponsor is ruggable rugs are machine washable spill
and stain resistant and they're non-toxic
they're great for protecting your hardwood floors and with code fun Linus
15 you can get 15 off your order and free shipping at the link below they're
available in the us and canada
now the latte panda alpha is more than just
you know the original macbook on a single pcb here in fact it's not
intended for what we're going to be using it for today at all do you want to
walk us through some of the things that make this particular device kind of
special here i don't know i guess there's only really two things it's really small and there's an arduino
right here along with rs there's a 232 and just a bunch of
general input output stuff so what this is is effectively like the same kind of
computer as uh something like a raspberry pi where everything is very
very embedded so there's your micro st expansion there's your display output
with a little nice little ribbon cable there and all that good stuff except it
is way more powerful so this thing runs
a core m3 7y30 CPU like i said before
eight gigs of RAM and there it is on the back the magic special sauce we're going
to be using today the dual m.2 adapters
in terms of the rest of the i o we've got touch interface for the display
Intel wireless over here nice got that rj45 Ethernet this HDMI port can do up
to 4k 60 which is really nice to see we've also got a headphone jack usb type
c and over on the other side three usb 3
type a's cooling is taken care of by this heatsink fan up here and that's
pretty much it so we can go ahead and uh get this thing set up on our box
test bench here shall we yeah sounds good to me
what what you doing
yes we have the same shirt on do do we want to address that or just
keep going lttstore.com
that's the good stuff right there literally costs more than 2x the entire
rest of the computer literally so
let's see here this is my old nemesis
the exp gdc beast that thing's back yeah
this thing's back we had so much trouble with this thing
the first time we tried to do a project with it and by we i mean alex
yeah it turns out that although it uses an m.2 adapter the signal is kind of
crap so depending on what laptop you put it in and how long the traces are
between the m.2 key and the CPU it can
just not work sometimes for no reason okay so we want to use our
m.2 key m for our graphics card is that correct
yeah and so this is where the keen among you have probably
realized that we have a bit of an issue because that is not an m.2 key or it is
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
anything that you would want to put in there basically you can't the main
difference between a key m and a key e
m.2 is actually the number of well aside from the number of pci express lanes the
position of the notch so there's a notch right here to ensure that you don't plug
the wrong thing into the wrong slot and the key e ah so the notch is way over
here now key m is intended for things like NVMe storage and in this case
our adapter to this pci express 16x slot
which should theoretically now have a 4x worth of bandwidth
key e is generally used for like wi-fi
cards so obviously we're not going to have any storage
if we don't find a way to put an SSD in here there actually are 32 gigabytes of
storage on the latte panda but that's enough not enough for like a game or
anything so oh well we could have just plugged an external drive in and ran our steam
library off that that would been slow no that would have been perfectly fast
you mean we waited around for this adapter for nothing i didn't know it had storage on it it
has storage on it well speaking of waiting around we had
to wait around because like you'd think that this would work it's a wi-fi
adapter to pci slot thing yeah you use
that use this guy right here plug it in like
so you'd think it would work but it just doesn't
okay cool which is why we need
this right here
did you just like stash pieces of this project all over the room
yes all right so this is from syntek
electronic co-limited and it appears to be
an e key to
m key adapter this is definitely increasing the bulk of our solution a
little bit but if it works then i'll be i'll be pretty pleased
curiously even though latte panda has a
key e here which normally is actually used with short cards like this one they
don't actually have like a mounting spot for it they've got an 80 millimeter
mounting spot just like if you were to plug in an SSD what were they thinking
um i just turned it over and figured that gravity would keep it in
good guy gravity all right so now that we've got our
single board computer our unnecessary storage and our pci express slot all
that we need to do now is plug in our
330 watt power brick to the beast here
look at this thing it's awesome so then we get power for
our car have you noticed a problem here yeah we
need two eight pins yeah let me guess you stashed it in a drawer
somewhere oh do you want to know where it is can you find it okay um
not in the banana cup
not in there
no you're like way off
we can play hot and cold if you want you're getting hotter much hotter
and a bit hotter you know you're getting colder now
you're getting colder in your pocket no it's not okay you're like pretty close
that's no you're you're colder now
do you want me to just get it for you this is painful yeah
oh we need a second yeah we have a whole power supply
so then can i summarize for the people at home now yep we've got the single
board computer with the e key to m key adapter for the
unnecessary storage we've got the m-key
2 pci express slot adapter for our titan
rtx now the beast down here is powered by
this dell power brick and then the plugs
at the top of the card are handled by this seasonic prime gold power supply
850 watts now we can turn it on well that's not plugged in but
other than that yeah type c power and i'm assuming this is
the power button here yep hey there we go nice okay so now it's just time for
gaming yeah you know what i don't see anything wrong in the menus so far
yeah it's going not bad everything here seems fine i'll just hit r and go
the uh the fan's definitely ramping up though yeah so you might have noticed
that we have a ping pong table over here yeah i did uh that's because the loading
times are absolutely atrocious so we're supposed to play
games while we wait for our video games yeah there's no point in like just
sitting in front of it like now my understanding is you're actually pretty
good at ping pong i'm like not bad
oh nice shot
ah
oh it's loaded now that's actually not that bad yeah
it's not great i was running these settings on an rtx 2080 mobile with a
mobile core i9 and i was getting about anywhere from double to triple that this
part's not bad with fewer people in the scene it's actually keeping up a little
bit better the part that i'm more concerned about is you can see some real
stutters like that
like it says 50 but it's like
the frame times are not
necessarily keeping up here yeah it gets pretty hot
yeah it actually smells hot you know like the smell of hot electronics
not really so technically we got a benchmark score
there uh but i get the feeling that this is kind of where the system
wasn't running properly okay we're going to call that a fail
oh wow our CPU was pinned at 100 the
whole time yeah holy banana sacks okay you want to
go ahead and fire up game number two all right well we have city skylines
here this is a trip this is even more CPU
intensive yeah also RAM what are you trying to do to this poor
thing we're pushing its limits you could say
cities on the brink of bankruptcy except the bailout i just reject it reject the
bailout yeah we're already 34 million dollars in the hole so
i don't think there's much coming back wow this is running at crud-tastic
details how's it doing about the same as
before looks like about 10 FPS 15 FPS
that might have been no it might have been more like 18 or so
yeah i've seen worse but like it works yeah it does work you could play this
yeah it's not a great experience no
we're definitely not getting the most out of our titan rtx time for our last
game the appropriately named doom oh yeah we can probably play ping pong
no
i'm trying to snipe the corner there i think it's my serve well actually we
just got to the main screen wow that was just launching the game
that's fantastic okay so we're vulcan ultra 1440p hey
that looks better this is actually not that bad
now it's not great to be clear
and you can also really see like the gpus serving frames about every three to
four milliseconds and the CPU is taking about every
20 or so so that is what is known as a severe CPU
yeah i'm pretty confident that if we put like
a 1060 into this the performance is going to be exactly
the same low ammo yes glory killed
like this is actually quite playable
so given how bottlenecked we are i guess that's the point of this then
yeah i'm very confident that we'll get the same performance with a 1060 as we did
with the titan so we were looking at about 50 to 60 frames per second in that
level of doom so why don't we fire it up with a gtx 1060 and see if we're looking
about the same
okay and that's it fire it up yeah
i mean it's now a good opportunity to talk about what this is actually for
sure i made this because it's the first
sensor that i could find there we go
and i think it's just running right now so going back to what i said earlier what
have you had to eat today uh i had a subway sandwich and a
crepe this morning hmm so i have built a fart detector
so this light right here turns on when this detects methane gas fascinating
so is the main benefit of this then that you can program your arduino on the
machine that also contains your arduino yeah and i think it would be really
useful if you're doing like iot stuff and you just had your arduino
like stuffed behind a mirror or something in your house and you could
just have Ethernet going to it and then you could
change everything right on your little computer from far away now the intent
was to use this in the bathroom right but it's not sensitive enough
yeah so we wanted to make the bathroom that never smells so instead of turning
a light on like on a breadboard it would turn it on outside of the bathroom and
turn the fans on so you'd know like someone really dropped a bomb in there
yeah but the problem is that methane only about 50 of people really produce it
when they flatulate so you want what is it
um dihydrogen oxide or dihydrogen sulfide
there we go which it turns out is really hard to get
sensitive sensors for got it that are like cheap so it would have
been like two grand or something dumb like that
is that worth it i don't know maybe
like i have definitely like walked into the bathroom and it's some unfortunate times
recently so and there we are we're running at
anywhere from 50 to 60 frames per second
exactly the same as we were on the rtx titan
that's pretty brutal so that my friends is what a CPU
bottleneck looks like you install a graphics card that's
literally half the performance and you
get zero change in FPS so all that's left for this video then is to light up
that blue light is it weird to message the group chat if
anyone like has gas today yes
but i think that if you acknowledge that it's weird it's fine okay
all right well no one heated our call so it also detects propane and butane so
we're just gonna blow some gas at it so if you guys are
into this kind of like uh iot maker stuff we actually have a really cool
