mario kart live home circuit isn't the kind of thing that we would normally
cover in a dedicated video on Linus tech tips but as one of the coolest
applications of augmented reality that i have seen
well ever it merited us giving it a try even
if it cost us almost 2 000 dollars in
equipment and pushing it to its limits as you can see under normal
circumstances you can race with up to four carts that is assuming that you
have four switches and perhaps the most difficult part for friends
with money but as we're about to see under more challenging circumstances
it doesn't necessarily pan out like this
the insane course that you're looking at here is not only enormous but we worked
around nintendo's multi-level limitation and we're gonna have some incredible
stakes the winner is going to end up with extra
vacation time for the year of 2020
that's right one good thing is finally coming out of this godforsaken year like
my segway to our sponsor ridgeball wants to redefine the wallet with its compact
frame and rfid blocking plates check out how they can keep your wallet bulge down
and use our offer code Linus to save 10 at the link in the video description
this is so cool i love this course
there's like there's obstacles lttstore.com
it's got everything you've got all these different surfaces that we're gonna
drive over like smooth reflective ones
crunchy ones metal ones we're gonna go over grates it was challenging to get it
up to this level though because the game actually doesn't recognize multi-level
courses and the cars aren't actually very powerful because the cars have to
go up really gradual incline or else they just get stuck and roll back down
and one more fun challenge recording the gameplay for you guys to enjoy now
normally the nintendo switch supports natively recording your gameplay onto
the device itself but whether it's because the camera is
running or the processing is too intensive or whatever the reason is
privacy nintendo doesn't allow you to record gameplay while mario kart live
home circuit is running so we had to set up external recording devices and of
course webcams get them face reactions for each one of our four switches
there's no limit to how big of a course you can make except for the distance
between all the multiplayer switches because there's one host switch and all
the other switches need to be near it and distance from each person's switch to the car we needed the switches to all
be in range no matter where in the room the cars went the thing to remember guys
is even under ideal conditions wi-fi particularly low latency video streaming
over wi-fi is challenging and as soon as
you've got a combination of multiple wireless devices all streaming video at
the same time along with additional peripherals like wireless controllers
you are basically creating a hot ugly soup of wireless signals bouncing all
over the place all in all this cost us i don't know somewhere between two and
three grand worth of hardware plus the recording setups plus all the time to
set it up so i really hope you guys enjoy it because i might be out more
money by the end of it mapping out your course is actually really easy all you
do is set it up and then drive the car where you want the course to be kind of
painting on the ground you set your gates up in order and drive through them and the one thing to be aware of is
drops the wheels need to stay in contact with the ground so in the case like over
here we actually put some tape on the on the course to make it more of a steep
hill than a drop off i'm ready to race boys
i'm just going to follow at a safe distance here so i can go around all the
people oh no no no i was in front of my controls are
not working oh man
come on you can do it buddy what why are you going back someone just bumped me
and moved me up the ramp yes nice i'm telling you the opposite there
we go there we go oh come on luigi
i gotta oh there's items
i want me them items
oh no i didn't get that oh get out of the way Anthony
hello
i can't move i know just stop stop for a second who's luigi stop
oh my gosh
uh i think i'm fine no i'm good i'm good i i i'm stuck i
think i think wait someone's got a laugh already
Linus get the out of my way get out you get out of my way

cannot control it oh
hey i need help i'm stuck
oh wait wait no no i'm okay i'm okay i'm okay what just happened to me i'm okay
i am not gonna fall yeah baby i'm gonna
pass get out of my lane
get out of the highway god
oh if Linus hadn't done that i had that i set up the drift perfect hadn't done
what raced properly
oh i guess oh my god
i'm stuck on the ramp oh laggy
i am not going to fall baby
you could say i'm a mario oh i'm stuck i'm stuck yeah
riley's a low priority what the heck oh yes yes
it's fine i didn't need you who just did someone just hit me
hello move it mario
you're mario okay okay wait i'm under the ramp right now come on wow is this
actually seven laps i can't
no
Anthony get the hell out of my way back up you're in my way no you're in my way
Anthony move you don't even need to pass me
go yes
Anthony doesn't deserve our sympathy there's a lot of crazy stuff in this
course but that one corner oh god i haven't been able to get through it
without reversing once your feed is so much better than mine look at mine
what are you talking about
i can't okay hold on i'm going to use your feed to drive my car here can i use
the truck you know i'd i'd just like to thank the uh mushroom the toadstool
brothers and uh for this uh for this wonderful occasion
you know i just um hey it's okay you know i can show i
can give you guys lessons at any time oh my god
the t is done you need a second winner i would
love to be but i'm stuck on this for some reason oh god what is this
out of my way oh my god lightning deal
sarah
okay it's kind of working right now or not
that's thousands of dollars well spent
what uh what a gaming experience i don't mind losing honestly but i don't like
losing because my equipment's malfunctioning i want to try like other
people's cars to see if it was like significantly worse
oh my god how did you not win by more yeah true i think i won by like two laps
this actually works oh this is really bad
oh my god riley's is so much better
tell you what sarah consolation prize you can have a day too because this is
clearly not fair that's so nice this is so stupid well
that was a total cluster but what went wrong
our Floatplane viewers who've had this video for over a week now had some
suggestions some of them i'm not sure if
i buy we had people saying they think it's because of our incline but honestly
testing worked just fine before everybody showed up and actually tried
to race and we had others suggesting that wiring up the switches for
networking would fix it now that's a good idea and that's one of the
things that i thought of at first except that our main problem was really the
video feed between the switch and the cart which is going to be wireless
regardless of how the switch itself connects to the internet for updates or
whatever so realistically what i think went wrong is a combination of factors
one there is a ton of rf
traffic going on in here everything from our studio lights to our microphones to
obviously all the wi-fi devices in this office
is running over the air and we have had weird problems like microphones going
suddenly or stuff like that the other one which i actually think is
the bigger one is that we had no control over which frequency our wi-fi was
running on so if it was on 2.4
i mean oh my goodness anything even a microwave could have interfered with the
signal and whether you're running 2.4 or
5 gigahertz large bodies of water can have disastrous effects on wireless
connectivity so even in our better scenario when we ran it upstairs and did
manage to have a successful race after the fact in fact you can see i'm still
connected to that one here some of our racers who were just three or four
meters away from me experienced some issues with their video feeds when their
carts were just driving around me lying there on the
floor so in conclusion when it works and works
well it is a ton of fun but if you push it to its limits
i wouldn't be surprised if you run into some problems the good news is most
people probably won't do that because it's like two grand in equipment to run
for racers just like it's
