oh
are
you
waiting
on
me
okay
well
you
might
think
that
this
is
some
kind
of
knock-off
emulator
handheld
like
an
rk2020
or
one
of
the
raspberry
pi
powered
ones
like
the
g
pi
or
the
pi
boy
but
no
this
is
a
real
honest-to-goodness
nintendo
wii
that
can
play
wii
games
gamecube
games
and
more
i
built
it
and
you
can
too

g-boy
is
the
brainchild
of
long-time
console
portabilizer
g-man
and
it
was
originally
called
the
wee
boy
on
his
development
blog
the
case
is
3d
printed
by
shapeways
using
nylonpowder
and
is
roughly
the
size
and
shape
of
an
og
nintendo
gameboy
having
finalized
the
project
roughly
halfway
through
2019
it's
now
available
for
purchase
as
a
kit
on
hopi's
site
bit
built
to
put
it
all
together
you'll
need
obvious
things
like
an
original
wii
console
and
a
micro
sd
card
to
hold
your
files
but
you'll
also
need
a
d-pad
and
face
buttons
from
a
nintendo
ds
lite
two
18650
lithium-ion
batteries
just
make
sure
you
get
these
from
a
reputable
source
to
avoid
counterfeits
and
some
tools
a
temperature
controlled
soldering
iron
and
a
rotary
cutting
tool
are
two
absolute
must-haves
to
make
it
work
i
mean
i
guess
you
could
use
a
saw
instead
of
a
dremel
but
come
on
to
make
life
easier
here's
a
list
of
some
other
stuff
you'll
need
with
the
most
important
being
the
wire
and
the
screwdriver
an
ifixit
protect
tool
kit
can
get
your
wii
apart
but
isn't
going
to
reach
far
enough
to
assemble
the
gboys
as
i
discovered
early
on
you'll
also
need
some
time
about
a
day
for
a
first
time
build
and
a
lot
of
patience
my
day
started
with
some
prep
work
which
included
soft
modding
a
stock
wii
console
using
letterbomb
which
allows
it
to
run
a
homebrew
software
and
setting
up
bitbelt's
bb
loader
which
allows
us
to
boot
into
a
new
home
screen
rather
than
the
nintendo
default
one
then
taking
it
all
apart
for
some
[Music]
physical
modding
as
you
might
imagine
fitting
one
of
these
into
this
involves
more
than
just
removing
the
motherboard
from
the
wii
it
actually
needs
to
be
cut
in
a
pattern
that's
lovingly
referred
to
as
the
omg
wtf
trim
yes
my
friends
this
is
literally
all
of
the
original
motherboard
i
am
going
to
keep
there
are
components
mounted
to
the
rest
of
the
board
like
the
real-time
clock
if
you
want
to
play
animal
crossing
and
the
bluetooth
chipset
if
you
want
to
connect
a
wiimote
that
will
need
to
be
harvested
and
reattached
if
you
wanted
to
do
that
but
that's
a
small
price
to
pay
time
to
get
out
the
dremel
before
assembly
the
edges
had
to
be
smoothed
out
in
order
to
prevent
anything
from
shorting
how
do
i
do
this
you
ask
sandpaper
it's
recommended
to
finish
it
with
no
lower
than
600
grit
and
focus
on
removing
any
copper
on
the
edges
by
going
in
at
an
angle
once
that's
done
a
little
desoldering
and
relocating
components
later
and
its
assembly
time
ltdstore.com
this
is
almost
entirely
just
a
matter
of
dropping
things
into
place
and
screwing
them
into
the
chassis
there's
a
lot
of
wires
that
need
soldering
and
power
needs
to
be
attached
to
the
correct
pads
and
only
those
pads
or
else
you're
looking
at
chopping
up
another
wii
bit
belt
recommends
using
some
extra
lengths
of
wire
as
impromptu
cable
ties
to
keep
this
mess
under
control
the
final
step
is
to
install
a
safety
thermistor
that
automatically
cuts
power
once
the
wii
reaches
70
degrees
that's
far
short
of
dangerous
thermals
and
the
only
time
this
should
happen
is
if
it
powers
on
in
an
enclosed
space
like
a
backpack
or
something
like
that
and
there
you
go
one
portable
wii
let's
take
it
for
a
spin
shall
we
and
just
like
that
here
we
are
in
an
open
space
for
the
linus
who
is
currently
fascinated
i
can't
believe
that
this
is
all
you
actually
need
from
the
original
wii
for
it
to
function
that's
all
the
logic
yep
the
ram
the
soc
gpu
i
mean
cognitively
i
know
that
yeah
you
know
uh
yep
okay
yep
there's
the
ram
there's
a
cpu
just
the
idea
of
chopping
up
a
pcb
of
a
device
this
complex
and
then
just
kind
of
trying
to
find
the
right
daughter
points
and
turn
it
into
something
like
this
is
just
unreal
to
me
i
love
it
well
i
mean
the
wii
is
one
of
the
more
researched
consoles
out
there
as
far
as
like
more
modern
machines
go
so
it's
not
really
that
surprising
that
people
are
like
hey
we
only
need
you
know
this
voltage
from
here
and
this
voltage
from
there
and
away
you
go
you
know
so
this
is
the
kit
that
you
use
then
yes
this
is
the
g
boy
rev3
i
want
to
try
it
yeah
i'll
go
over
here
okay
this
is
kind
of
where
i'm
gonna
live
for
the
rest
of
the
video
okay
cool
let's
crack
open
my
copy
of
legend
of
zelda
twilight
princess
and
uh
yeah
now
would
be
a
good
time
to
mention
that
you
should
probably
rip
your
games
from
the
wii
before
you
do
the
mod
this
thing's
got
no
optical
okay
this
is
so
cool
i
mean
the
battery
life
can't
be
very
good
though
i
haven't
really
tested
the
battery
life
i
think
it's
a
couple
of
hours
like
it's
not
amazing
but
so
it's
like
the
game
boy
experience
in
more
ways
than
one
kind
of
wish
the
screen
was
a
little
better
than
this
but
uh
that's
the
screen
that
comes
with
it
i
think
if
you
really
had
a
mind
too
there
are
probably
some
ips
displays
that
have
like
independent
brightness
controls
and
all
that
kind
of
stuff
the
menu
where
you
were
on
is
called
bb
loader
and
that
was
created
especially
for
this
kind
of
device
like
a
portable
device
that
doesn't
necessarily
have
uh
shall
we
say
uh
motion
controls
built
in
right
so
they
were
cut
off
yeah
i
don't
remember
if
i
put
the
bluetooth
module
back
in
that
so
pairing
a
wiimote
is
gonna
be
hit
or
miss
the
sound
is
surprisingly
good
even
if
the
screen
ain't
great
uh
yeah
if
you
wanted
to
uh
turn
the
volume
up
you
should
just
be
able
to
hold
the
y
button
and
the
z
button
and
press
up
on
the
d-pad
yeah
sorry
is
the
z
rear
is
that
is
where
uh
we're
right
but
it's
above
the
trigger
oh
okay
it
distorts
a
little
but
that's
fine
it
was
already
very
loud
before
that
yeah
the
amplifier
circuit
i
think
uh
kind
of
goes
a
little
bit
too
hot
for
those
speakers
yeah
if
you
put
it
too
high
but
you
know
that's
how
you
know
that's
how
you
know
it's
good
link
a
nope
this
is
crazy
yeah
it's
not
an
emulator
it's
straight
up
playing
the
game
like
what
fun
fact
twilight
princess
is
reversed
on
the
wii
versus
gamecube
i
did
know
that
because
link
is
left-handed
yep
whereas
the
majority
of
the
population
is
right-handed
i
don't
know
where
the
horse
is
one
thing
that
you
do
lose
with
a
control
setup
like
this
is
analog
triggers
so
those
are
just
straight
up
digital
but
of
course
if
you
just
wanted
to
play
wii
games
on
the
go
there
are
maybe
less
legal
well
i
don't
know
i
mean
does
this
the
fact
that
i'm
running
okay
so
i'm
running
ripped
software
but
on
nintendo's
own
hardware
what
is
nintendo's
take
on
this
i
think
nintendo's
take
is
you
need
to
buy
it
again
you
gotta
buy
it
again
but
this
is
my
hardware
right
that's
your
hardware
but
you
only
have
a
license
to
run
that
game
on
that
disk
on
that
disk
whereas
you
know
there
are
laws
that
say
that
format
shifting
is
a
thing
that
you
can
do
nintendo
doesn't
necessarily
agree
with
that
nintendo
doesn't
agree
okay
so
then
you
know
since
we're
doing
something
nintendo
doesn't
approve
of
anyway
here
there's
definitely
ways
that
you
can
more
easily
and
more
cheaply
play
wii
games
on
the
go
so
this
is
going
to
have
to
justify
its
existence
in
some
other
ways
fortunately
it
is
homebrewable
af
so
why
don't
we
go
back
to
that
launcher
and
have
a
look
at
what
else
we've
got
on
here
just
power
it
off
and
back
on
again
oh
is
that
the
only
way
i
don't
know
if
it's
the
only
way
but
there's
not
a
whole
lot
of
documentation
on
the
like
button
shortcuts
does
it
have
like
an
ac
plug-in
so
that
you
can
uh
just
run
it
not
on
batteries
oh
i
guess
it's
got
type
c
yeah
oh
that
is
so
cool
and
when
the
unit
is
off
type
c
actually
automatically
switches
it
over
to
the
internal
storage
so
you
can
just
connect
it
up
to
your
pc
and
browse
the
files
this
just
blows
my
mind
okay
so
right
now
i
only
see
gamecube
games
okay
if
you
use
the
right
stick
yeah
that'll
bring
up
a
radial
menu
so
you
can
choose
wii
games
uh
the
hbc
logo
is
for
homebrew
channel
games
which
would
be
things
like
snes
emulator
and
a
few
other
things
uh
i
think
this
early
version
of
the
software
doesn't
currently
support
running
we
wear
titles
and
virtual
console
but
that
is
something
that's
going
to
be
coming
okay
so
virtual
console
okay
so
that's
gamecube
games
for
some
reason
uh
yeah
the
virtual
console
menu
doesn't
work
so
it'll
just
keep
you
where
you
are
i
see
okay
what
about
wii
games
wii
games
don't
work
oh
hey
there
we
go
wii
games
do
work
wow
sick
so
like
yeah
mario
kart
wii
suckas
this
uses
a
compatibility
layer
slash
hack
called
hedra
which
allows
it
to
actually
emulate
the
wii
mode
so
you
don't
have
to
worry
about
having
to
hook
up
an
external
wiimote
you
can
use
the
sticks
it's
actually
not
crazy
worm
no
it
shouldn't
get
that
hot
well
i
don't
know
i
mean
it's
a
home
it's
a
living
room
console
like
i
i
didn't
i've
never
given
much
thought
to
how
much
heat
it
outputs
well
the
full
unit
only
really
has
a
tiny
little
heat
sink
and
fan
on
it
yeah
i
guess
that's
all
we
got
on
there
now
nah
i
missed
okay
no
come
on
so
lame
[Music]
who
blue
shells
you
right
before
the
finish
line
bad
people
that's
who
mario
you
piece
of
human
garbage
well
we
all
know
and
have
known
forever
that
the
ai
cheats
in
mario
kart
yeah
just
like
oh
stop
all
right
yes
i
reign
supreme
so
how's
the
experience
with
wii
games
great
perfect
yeah
the
fact
that
it's
actually
a
good
experience
is
the
result
of
quite
a lot
of
community
effort
it's
not
just
gman
i
believe
um
some
of
the
pcbs
that
were
custom
built
were
made
by
aurelio
on
the
bit
built
forums
and
there
are
several
others
who
contributed
um
all
kinds
of
research
and
time
and
effort
into
all
of
this
so
it's
really
a
very
team
effort
kind
of
thing
it
was
just
all
kind
of
put
together
by
g-man
uh
9x
gx
is
the
super
nintendo
emulator
that
you
can
use
in
lieu
of
virtual
console
which
currently
doesn't
work
sick
most
of
these
menus
don't
do
anything
yeah
this
is
really
early
software
got
it
they
just
released
it
back
in
june
okay
got
it
yeah
so
it's
nest
nine
and
xgx
holy
smokes
this
is
it
this
is
everything
okay
what
i
need
to
know
though
is
super
mario
world
does
it
actually
run
well
[Music]
i
have
my
doubts
love
this
4x3
display
well
yeah
i
have
my
doubts
because
like
getting
the
latency
good
is
something
i've
seen
a
lot
of
people
screw
up
there
would
be
more
latency
with
a
wiimote
though
okay
we're
going
to
try
it
we're
going
to
try
playing
super
mario
world
with
a
analog
stick
i've
never
actually
done
this
before
and
it
feels
a
little
bit
a
little
spongy
i
guess
the
nintendo
ds
lite
had
kind
of
spongy
buttons
anyway
didn't
it
it's
hard
to
play
super
mario
world
on
anything
other
than
a
snes
controller
especially
if
you're
used
to
that
sort
of
thing
like
to
be
clear
it's
not
like
i'm
missing
my
jumps
and
stuff
here
[Music]
but
these
yeah
these
buttons
are
really
not
they're
really
really
not
great
that
may
be
a
side
effect
of
the
3d
printed
shell
maybe
some
sanding
would
help
with
that
what
other
consoles
can
you
run
emulated
games
for
uh
well
anything
that
has
a
wii
emulator
for
it
so
dosbox
is
available
scum
vm
so
like
old
lucasfilm
or
lucasarts
games
psychogenesis
regular
nintendo
there's
an
n64
emulator
that's
sort
of
okay
what
else
gpa
regular
game
boy
game
gear
master
system
okay
so
yeah
the
the
wii
is
actually
a
really
good
like
retro
console
emulating
emulating
system
why
this
over
someone
like
one
of
those
super
portable
pcs
well
i
mean
there's
the
simplicity
of
the
interface
for
one
and
two
i
mean
did
you
build
that
super
portable
pc
okay
that's
fair
oh
no
yoshi
oh
wow
that
was
some
hardcore
slow
down
right
there
yeah
this
this
d-pad
leaves
a
lot
to
be
desired
it's
starting
to
heat
up
a
little
bit
too
i
can
feel
it
the
good
thing
about
the
d-pad
and
the
buttons
and
everything
like
that
that's
all
stuff
that
you
can
swap
out
yourself
so
you
can
get
different
rubber
membranes
you
can
get
different
you
know
d-pad
face
buttons
that
kind
of
stuff
if
you
really
didn't
like
it
ah
no
not
the
big
crushing
things
i
thought
these
were
swamps
for
the
longest
time
because
i
was
a
little
kid
and
i
couldn't
actually
like
get
very
far
in
the
game
and
like
i
read
the
manual
obsessively
remember
when
like
reading
the
game
manual
was
as
much
fun
as
playing
the
game
i
used
to
do
it
in
the
car
all
the
time
oh
yeah
it's
not
that
heavy
no
oh
well
there's
your
cooling
problem
we
have
tape
over
the
vent
come
on
boys
let's
give
it
some
breathing
room
there
we
go
and
look
if
i
get
straight
onto
the
camera
that
actually
gives
you
guys
a
better
look
at
what
it
looks
like
if
you're
straight
onto
it
it's
not
that
bad
no
yoshi
very
cool
i
don't
know
that
i
would
personally
put
the
time
and
effort
into
building
one
of
these
versus
like
you
know
using
a
um
a
gpd
type
device
or
something
like
that
instead
but
there
is
absolutely
nothing
else
like
it
and
look
at
that
it's
got
a
headphone
jack
at
325
dollars
plus
the
cost
of
batteries
sd
card
face
buttons
and
a
wii
this
project
is
not
for
the
faint
of
heart
it's
really
less
of
a
practical
thing
and
more
of
a
passion
project
sort

video
for
the


it's construction time again so on the one side of my home office I've got that server cabinet that's full of networking gear gaming rig servers battery backups the whole nine yards and on the other side of it in this room I've got a whole lot of nothing time to fix that today I will be constructing what I call TM the world's most comfortable gaming setup so come along for the ride cooller masters master case maker five features they're freeform modular system allowing you to customize adjust and upgrade make it yours at the link in the video description so first things first we're going to take this Samsung 65 inch curved su HDTV up to the room and do a test fit something that I actually have not done yet so the position of the TV is actually going to be one of the things that makes this the most comfortable gaming setup we could have just put it against the wall right here and put like a chair over here and call it a day but no that is not the world's most comfortable so now the TV is actually going to mount to this 55 degree wall and the viewer will actually sit right here there we go of course this is not that comfortable and this the pillow sack provided by loveSac comm is the solution to that problem let's get this in there so what makes this the optimal piece of furniture a beanbag chair is that I can get the user reclined at exactly the angle that the TV will be at above him see that oh yeah hey do you guys mind throwing the TV up here so I can see what the viewing distance is gonna look like I'd imagine this is what it's like to be ludicrously wealthy you wouldn't actually mount anything you would just have like you would just have staff on hand that would just move things and hold them wherever you need them so it'll probably be about eight or twelve inches off the wall this is going to be freaking sick okay thanks guys awesome let's get started but we've got some challenges to overcome in here first the Kenai dam um you might have noticed that this room other than this horrible light fixture up here has no power no network and in fact has no insulation just like the one on the other side and if you're going to have a most comfortable gaming setup well the plan better be to have it in an insulated room don't you think in fact the only electronics in this room right now are this Chubb caretaker from what appears to be this chip was manufactured in 92 okay somebody spread that insulation around well that explains why the garage was so cold during the early days of lioness Media Group we were all working over there there was no insulation if we want to come quite low because remember it's little kids okay so I'm thinking for instead of trying to match the base in here we'll just go with a flat stock trip with everything ripped off the wall let's go through the plan in a little bit more detail it's changed a fair bit from the original concept and now it's going to be kind of like a cool kids play area as well so this hunk of wall right here is actually going to have a framed like metal plate that goes down to about here it's going to be like a cool magnet wall this right here is going to be power for a reading lamp and right here is going to be another beanbag kind of a lounger that's kid sized for them to sit and read the bookshelves will be covered in books and DVDs and games and then here we've roughed in the spot where the TV is going to go so we play it around with our mount a little bit and it looks like it's going to end up on I believe it was yep it's going to go as far left as it can on these two so our power is going to come out kind of in the center and then our data connection so we're going to have Ethernet for the back of the TV as well as Samsung's one connect do that right here so that way all of our HDMI inputs can actually be over here on this wall and just this one cable needs to run between that and the TV itself over on this wall I'm going to have everything wall mounted PC Xbox Network switch so that everything has networking running over to the other room and anything else that I could see fit including this one connect box itself which is going to be powered Oh doesn't use separate power that's cool I guess it's powered by the TV this box right here is going to provide power for everything that's mounted to this wall and is also going to give us with the access panel that we're going to build in over here the ability to vent this room later on in the future if we decide to do that but we may not up here we're going to do two 6-inch dimmable pot lights and then the room itself I believe the ceiling is going to be black and the walls are going to be kind of brightly colored and and fun so hopefully we have enough light but we can get it dark enough for a really great movie gaming experience this crappy little side table from Ikea is going to be cut off and is going to be beanbag chair height and is going to sit right here next to the beanbag with another little lamp on it just in case you want to sit on this one and read and the carpet is going to be replaced because who puts artificial turf in their house ok Linus so that's great that's what everyone but you is doing what are you actually contributing to this project ah yes I have something I am going to be building a sick wall-mounted computer to go in that room to power the gaming experience on the ceiling mounted TV how do you build a wall-mounted computer well you could DIY it I guess but I'm going to be taking the easy route using a Lele PCO 6sx let's get this baby put together so for the motherboard we went with a Maximus 8 Jean this is pretty much the no compromises M ATX board for LGA 1150 it's a Ford's SLI and crossfire it's got all the outputs you could want and build quality to match our CPU and RAM choices are admittedly kind of overkill we're using a core i7 6700 K quad core with hyper threading and 32 gigs of Corsair Vengeance lpx ddr4 memory but I mean hey maximum comfort requires maximum performance right right this is a really cool case they've got some cases astonishingly to add thermals see it's a lot of things like this that drive me crazy with not just lately all case manufactures you couldn't spring for three more zip locks every computer manufacturer hates me personally gtx 1070 feels like a perfect choice for this machine cross threading it all right so this baby's ready let's bring it back upstairs and find something else to do I'm going to be taking some of the leftover cat 5e cable from my how to run Ethernet outside your house video which you can check out right over here I'm going to be running it from my server room across the peak I'm actually going to have to crawl through a crawl space in my attic over to the new room so that you know whether it's games or whether it's Netflix I don't have to worry about a wireless connection being a bottleneck wired only baby you know what I'm gonna get myself a head lamp hold on I'm gonna poke a wire through over there first did ya go well I'm back in so are you going to the other side now yeah I'm gonna fall all the way to the other side can't wait for you to add the other side yeah you might be able to see me if you poke your head in okay so this clip is having just gone in from the server room I have to crawl through that hole oh my god Dennis just fell down yes what the hell Dennis please don't fall through my ceiling Dennis did you put your foot through my ceiling oh my god you oh my god I always been up on your phone your cookstove crotch oh man yeah I know the thud oh god dammit Dennis I almost died so we interrupt this program to bring you stunning footage of the damage that Dennis has done to my house there's the brand-new hole in my ceiling of my garage that we had not intended to put there is this a bit of a blue no it is not supposed to be made of wood Dennis not it's supposed to invade a drywall so from now on I'm gonna call this the Dennis hole hi Dennis serious thing and cheese all right okay come on back up here and let's see if I can crawl back where I'm supposed to be I could have done so you know I only step on the pieces of wood dentist that is how you're supposed to do it how did you know that um I thought everything not that I would let Dennis have any but blue apron allows you to create delicious chef inspired food at home they deliver all the farm-fresh ingredients you need right to your doorstep in exactly the right proportions no trip to the grocery store no waste from unused ingredients they've got a couple of different plans there's the two-person plan and the family plan and blue aprons recipes are delivered in a refrigerated box so the ingredients will stay fresh even if you're not at home when your package arrives they offer a huge selection of recipes and are always adding new dishes to the menu every week there is no commitment you can skip or cancel the service at any time if you're going on vacation or you've got a special occasion and each menu is between 800 and 500 calories per person but the best part for me is that all the meals can be prepared in 40 minutes or less meaning that blue apron actually takes less time than going out to eat not to mention that you're learning to make these recipes so hey you're picking up a new life skill while you're at it it's available in the USA and the first 200 people will get three free meals off their first order using the link in the video description so I think I've got enough for today let's call that part one of the world's most comfortable gaming setup we'll be back with the finished product in part two but in the meantime guys if you dislike this video hit that dislike button if you liked it hit the like button get subscribed maybe even consider supporting us you can buy a cool shirt like this one at the link in the video description you can join our community forum where you can ask questions get questions and

oh
hi
everybody
me
moudahar
welcome
to
today's
video
brought
to
you
by
our
friends
over
at
manscape.com
the
people
who
are
taking
over
the
world
and
yes
you
heard
me
taking
over
the
world
they
just
introduced
the
fourth
generation
electric
body
trimmer
the
lawnmower
4.0
into
the
market
globally
which
means
international
shipping
to
the
united
states
canada
australia
the
uk
basically
all
of
europe
singapore
and
south
africa
the
first
stop
to
the
galaxy
of
luxury
nut
shaving
comes
down
to
the
lawnmower
4.0
which
actually
comes
these
replaceable
ceramic
blades
with
skin
safe
technology
and
a
built-in
led
by
the
way
so
basically
you
can
shave
your
balls
without
worrying
about
any
nicks
and
bruises
and
let
me
tell
you
right
now
okay
before
i
used
to
be
scared
of
putting
the
blade
up
to
my
balls
now
my
pews
fly
away
like
harry
houdini
let
me
tell
you
they
just
disappear
and
if
you're
worried
about
shaving
that
black
hole
of
yours
trust
me
it's
it's
safe
all
the
way
down
there
too
and
if
you
don't
trust
me
i'll
do
it
with
you
i
promise
apparently
the
big
brains
over
at
manscape
were
so
inspired
by
nasa
that
they
had
to
make
the
brand
new
cool
wireless
charging
system
so
you
can
actually
see
how
much
battery
you
have
down
here
i
don't
even
wirelessly
charge
my
own
phone
but
when
it
comes
to
my
ball
trimmer
you
bet
i'm
gonna
use
that
new
technology
they
also
have
this
new
travel
lock
feature
they
want
me
to
tell
you
about
which
is
great
if
you're
ethnically
challenged
like
me
imagine
going
into
an
airport
and
then
just
having
an
actual
live
blade
in
your
luggage
not
exactly
the
thing
you
want
in
fact
it's
so
easy
to
use
even
a
monkey
could
do
you
just
tap
like
three
times
over
here
and
bang
it
won't
let
me
use
my
blade
don't
worry
it's
as
easy
to
unlock
don't
worry
and
if
you
get
into
the
launch
plan
right
now
they
actually
come
with
the
crop
preserver
ball
deodorant
and
crop
reviver
ball
toner
spray
and
these
are
perfect
for
those
little
asteroids
when
they're
orbiting
around
the
sun
all
day
manscape
decides
they
want
to
go
for
company
in
the
millennium
by
actually
having
a
good
old-fashioned
nose
and
ear
hair
trimmer
the
weed
whacker
to
be
more
specific
have
you
ever
tried
pulling
a
nose
hair
how
things
hurt
like
no
tomorrow
but
with
the
weed
whacker
oh
life
just
gets
a
lot
easier
and

you
get
that
full
performance

thank
you
oh
muda
that's
a
juicy
title
right
there
you
made
the
muda
phone
well
kind
of
uh
ladies
and
gentlemen
over
a
week
ago
i
ripped
on
something
called
the
freedom
phone
a
phone
that
was
completely
uncensored
with
unsensitable
app
stores
pre-loaded
applications
the
first
privacy
free
speech
operating
system
i
guess
now
ladies
and
gentlemen
there
is
clearly
a
political
side
this
phone
caters
to
it's
not
just
making
america
great
but
also
making
a
great
phone
uh
of
course
news
media
ripped
on
this
a
fair
bit
okay
they
they
definitely
didn't
like
this
the
meant
for
trump
supporters
straight
up
telling
you
warning
over
the
new
freedom
phone
that
claims
to
protect
your
privacy
now
ladies
and
gentlemen
i
i
laughed
at
this
phone
because
i
think
it's
a
grift
okay
at
the
end
of
the
day
it
seems
like
a
grift
for
me
uh
it's
a
it's
most
likely
a
hundred
to
two
hundred
dollar
phone
that
has
a
custom
privacy
rom
probably
something
like
lineage
os
flashed
onto
it
and
sold
right
to
you
or
sorry
freedom
os
now
back
when
i
made
the
freedom
phone
video
i
was
laughing
at
the
idea
of
this
being
a
grip
but
if
you
think
i'm
laughing
at
the
idea
of
this
actually
being
a
logical
idea
you're
wrong
because
i
think
having
a
phone
that's
detached
from
google
amazon
microsoft
really
big
tech
in
general
uh
is
a
good
idea
okay
having
a
phone
that
isn't
constantly
being
pinged
for
its
location
camera
microphone
accesses
is
a
good
thing
now
i
laughed
at
this
because
this
is
a
500
device
that's
again
may
i
reiterate
in
my
opinion
a
like
one
to
two
hundred
dollar
device
being
just
dropshipped
to
you
with
a
custom
rom
installed
and
it's
something
that
you
can
do
yourself
now
of
course
while
i
laugh
at
something
i
think
it's
unfair
for
me
to
just
laugh
at
this
and
not
show
you
how
to
do
it
which
is
what
this
video
is
all
about
so
how
are
we
going
to
build
this
for
one
this
is
a
android
only
affair
so
if
you're
on
an
apple
device
well
this
isn't
going
to
be
for
you
apple
devices
are
different
okay
apple
it
makes
the
hardware
they
write
the
software
and
they
converge
it
together
there
is
no
open
source
in
the
world
of
apple
now
android
is
not
the
same
across
the
board
you
can't
modify
every
phone
my
daily
driver
is
a
samsung
fold
and
while
i
love
this
thing
to
death
you
can't
modify
it
with
any
google
device
at
all
that's
because
android
requires
you
if
you're
going
to
write
it
yourself
to
have
device
vendor
ids
and
hardware
ids
and
a
lot
of
android
phones
specifically
in
that
higher
end
market
are
actually
very
proprietary
see
android
is
kind
of
like
a
foundation
okay
and
a
lot
of
manufacturers
like
samsung
like
sony
uh
asus
oneplus
will
actually
build
their
own
proprietary
stuff
on
top
now
some
companies
are
real
nice
like
oneplus
from
what
i
know
just
ends
up
making
everything
open
source
which
is
great
oneplus
devices
are
awesome
to
make
things
easier
for
myself
i
decided
to
go
to
google
and
buy
their
pixel
now
you
might
be
like
whoa
moody
you're
talking
about
decoupling
from
google
okay
you're
buying
one
of
their
phones
to
build
the
muda
phone
yes
okay
the
reason
why
i'm
doing
this
is
because
google
pixel
devices
or
nexus
devices
if
they
still
even
make
them
are
sort
of
like
the
origin
point
for
android
launches
all
right
this
is
the
first
device
that
basically
gets
the
newest
version
of
android
if
you
want
that
pure
stock
android
experience
i
don't
think
you're
gonna
get
much
better
than
a
pixel
the
reason
why
i'm
also
picking
this
is
for
349
dollars
you're
getting
a
far
better
device
now
the
and
the
google
pixel
4a
in
this
case
isn't
the
most
expensive
device
you
can
get
you
can
get
a
499
device
with
5g
you
can
even
get
a
pixel
5
which
is
like
600
700
us
that
is
far
better
now
this
is
these
aren't
like
super
amazing
devices
isn't
like
the
highest
end
like
two
thousand
dollar
smartphone
android
ranges
but
just
to
tell
you
they
end
up
getting
5.8
inch
full
hd
oled
displays
which
i
would
say
are
probably
some
of
the
best
in
the
market
that
you're
gonna
get
you
get
a
pretty
good
battery
uh
4g
or
5g
depending
on
how
much
money
you're
deciding
to
drop
a
12
megapixel
dual
pixel
camera
okay
which
as
far
as
the
google
cameras
go
i'm
not
a
camera
aficionado
go
watch
a
marquis
brownlee
video
for
that
they
look
good
to
me
and
they
come
with
a
snapdragon
730
or
a
765
g
which
again
those
are
pretty
decent
gr
processors
i've
been
able
to
play
most
of
my
games
on
there
and
the
system
the
entire
phone
runs
smooth
so
again
this
isn't
a
phone
review
for
349
in
my
opinion
you're
getting
a
better
device
than
the
freedom
phone
okay
so
now
that
we
have
basically
gone
on
what
device
i'm
buying
all
you
really
need
to
do
is
buy
the
device
grab
it
in
your
hands
and
start
flashing
a
custom
rom
onto
it
now
at
this
point
i
could
tell
you
to
download
any
of
the
privacy
focused
open
source
roms
out
there
like
lineage
os
and
just
install
it
and
that
would
be
the
end
of
the
video
see
if
you
really
care
about
your
privacy
and
freedom
and
want
to
go
every
step
of
the
way
maybe
you
should
build
the
entire
operating
system
on
your
own
device
and
that's
where
the
real
fun
begins
buckos
so
building
android
isn't
exactly
the
toughest
thing
that
you're
gonna
do
you're
gonna
want
some
g-fuel
in
your
system
because
it's
gonna
take
a
long
time
all
right
code
sog
by
the
way
now
building
android
is
a
bunch
of
little
steps
that
you're
gonna
have
to
go
through
it's
more
time
consuming
than
it
is
actually
technical
but
uh
you're
gonna
need
a
pretty
strong
system
to
do
it
okay
and
something
along
the
veins
of
six
threads
minimum
so
here's
the
system
specifications
for
my
virtual
machine
now
in
this
system
i've
got
12
threads
that
i'm
passing
through
so
i
guess
it's
kind
of
like
if
you
wanted
to
compare
to
a
real
system
like
six
cores
hyper-threaded
right
you're
also
going
to
want
to
have
to
have
52
000
gigabyte
sorry
52
gigabytes
of
memory
if
that
sounds
like
a
typo
it's
not
okay
initially
i
gave
this
32
gigs
of
ram
because
i
thought
that
was
enough
but
it
actually
crashed
during
the
build
so
i
ended
up
giving
it
like
52
000
didn't
use
anywhere
close
to
the
full
amount
but
at
least
it
finished
a
build
and
uh
that's
pretty
much
it
ladies
and
gentlemen
now
if
that
sounds
like
a
lot
of
memory
we're
building
an
os
okay
if
you
don't
have
this
stop
the
video
right
now
you're
not
going
to
be
able
to
build
the
operating
system
so
now
that
that's
done
we
need
to
have
an
operating
system
right
and
for
this
we're
going
to
use
linux
now
you
don't
have
to
install
linux
to
a
computer
you
can
do
this
all
under
a
virtual
machine
so
go
and
download
vmware
or
virtualbox
i
went
with
vmware
vmware
player
which
is
actually
free
to
use
for
personal
reasons
download
that
and
then
go
to
ubuntu.com
and
download
the
ubuntu
basically
go
to
their
website
click
on
download
and
under
desktop
you
want
to
click
21.04
okay
you
can
go
the
lts
but
just
go
with
the
newest
one
and
it'll
let
you
download
an
iso
file
now
under
vmware
which
is
what
i
used
install
the
actual
thing
like
you
normally
would
so
basically
create
a
new
virtual
machine
follow
the
steps
and
it
actually
should
auto
install
ubuntu
uh
if
it
doesn't
installing
ubuntu
isn't
that
terribly
difficult
you
boot
into
it
you
click
next
a
bunch
of
times
and
it
should
be
okay
all
right
follow
the
instructions
now
when
all
of
that
is
done
you
should
be
at
the
ubuntu
home
screen
now
yours
is
going
to
look
a
little
bit
different
meaning
that
you
don't
actually
have
all
these
extra
folders
most
likely
uh
these
two
in
specific
but
uh
you're
gonna
be
at
this
home
screen
right
and
that's
two
testicles
by
the
way
i'm
sorry
ubuntu
that
wallpaper
is
too
dirty
for
me
to
have
around
the
house
here
you
can
actually
read
what
google
is
using
to
build
the
operating
system
they've
got
72
core
machines
with
64
gigs
of
ram
yeah
no
it
doesn't
crash
for
you
google
that
takes
40
minutes
by
the
way
so
you're
probably
not
gonna
have
that
system
unless
you're
like
one
of
those
thread
ripper
boys
and
girls
so
in
that
case
it's
gonna
take
a
lot
longer
for
you
all
right
i'm
going
to tell
you
this
process
is
a
long
one
the
sun's
going
to
come
up
before
we're
even
done
so
the
first
things
first
we
have
to
install
the
necessary
packages
on
the
workstation
okay
so
number
one
let's
click
on
this
link
and
basically
takes
us
to
this
page
where
we're
going
to
establish
a
build
environment
now
again
do
this
underneath
linux
because
that's
what
google
wants
you
to
use
all
right
don't
try
doing
this
on
a
mac
i
don't
even
think
you're
going
to
be
doing
this
on
windows
so
what
you're
going
to
do
is
you're
going to
go
to
the
very
first
line
where
it
says
ubuntu
18.04
you're
going
to
copy
the
code
sample
by
clicking
this
button
right
here
and
then
you're
going
to
click
these
uh
nine
squares
so
the
application
drawer
and
you're
going
to
type
in
the
words
terminal
now
this
takes
you
to
your
home
directory
right
so
thickens
dash
virtual
machine
that
comes
is
the
name
of
the
virtual
machine
okay
if
you
couldn't
figure
it
out
now
you're
going
to
right
click
and
you're
going
to
paste
this
all
right
this
is
basically
going
to
be
all
of
the
dependencies
that
you're
going
to
download
now
one
of
the
things
that
you
also
want
to
do
is
type
in
lib
n
curses
five
they
actually
include
this
like
right
here
on
on
this
part
of
the
actual
line
but
uh
you're
gonna
want
this
as
well
because
it
actually
crashes
during
the
build
for
some
reason
so
hit
enter
and
you're
gonna
enter
the
password
so
this
is
the
root
password
for
your
account
so
your
login
account
password
mine
is
one
two
three
hit
enter
and
basically
it's
gonna
tell
you
it's
telling
me
that
it's
already
installed
but
for
you
it's
gonna
install
this
it's
gonna
ask
you
if
you
to
install
it
hit
yes
and
it's
going
to
do
all
the
work
for
you
once
that's
done
it's
time
for
you
to
go
back
to
this
page
and
in
number
two
while
still
in
a
terminal
install
repo
and
gain
credentials
so
this
is
the
repository
tool
that
we're
going
to
be
using
in
order
to
actually
build
or
sorry
download
the
source
tree
okay
so
in
this
where
it
says
working
directory
let's
call
this
moda
phone
all
right
just
for
the
sake
of
clarity
now
what
it's
going
to
do
is
going
to
ask
you
to
make
directory
moda
phone
now
again
you
want
to
use
the
same
terminal
why
that's
because
it's
set
to
the
home
directory
okay
you
see
how
it
has
the
tilde
key
it's
in
the
home
directory
so
you're
going
to
type
make
dir
moda
phone
you
could
have
just
copied
it
but
i'm
just
showing
you
it
by
typing
then
you're
going
to
do
cd
which
is
change
directory
and
then
you're
going
to
do
mooda
phone
pro
tip
in
the
terminal
use
the
tap
key
and
it'll
just
autofill
everything
for
you
so
it's
like
terminal
tricks
right
just
do
it
right
do
it
real
quick
so
here
you're
going
to
make
sure
you
set
your
git
all
right
to
a
registered
google
account
uh
i'm
just
going
to
call
it
mudahar
on
us
which
is
my
name
and
i'm
going
to
call
it
muda
admuddafuda.com
all
right
again
i'm
just
doing
this
for
the
sake
of
you
know
uh
for
the
sake
of
the
video
use
your
actual
registered
google
accounts
okay
this
is
what
you're
going
to
be
using
if
you
want
to
do
code
reviews
right
so
again
you're
going
to
copy
this
and
you're
going
to
paste
this
and
i'm
actually
going
to
use
my
real
account
so
i'm
just
going
to
copy
and
paste
this
the
way
that
i
wanted
so
we'll
just
skip
that
so
once
you've
copy
and
pasted
all
these
two
lines
then
you're
going
to
run
repo
init
all
right
now
if
you
run
repo
in
it
like
itself
it's
probably
not
gonna
work
for
you
okay
and
that's
because
you
need
to
get
something
called
repo
okay
and
that's
where
you're
gonna
have
to
initialize
it
so
click
on
this
little
link
up
here
called
installing
the
repo
client
and
here
you're
going
to
install
repo
by
following
these
exact
steps
so
you're
going
to
make
directory
and
you're
just
going
to
do
this
make
bin
you're
going
to
do
path
all
right
right
here
and
you're
going
to
do
and
you're
just
going
to
copy
and
paste
these
lines
then
you're
going
to
download
the
repo
launcher
ensure
it's
executable
so
again
copy
this
so
curl
which
is
where
we're
going
to
download
this
uh
this
tool
from
hit
enter
it's
going
to
download
it
then
we're
going
to
use
chmod
to
make
that
executable
so
again
it's
just
copy
and
pasting
right
very
simple
a
monkey
could
do
it
then
you
can
optionally
verify
that
the
launcher
matches
the
signature
so
you
can
paste
these
lines
in
and
that's
just
to
make
sure
all
of
it
is
from
google
and
you
didn't
get
hacked
in
any
single
way
and
get
something
sort
of
weird
once
that's
done
now
you
can
go
back
to
the
initializing
a
repo
client
page
so
where
we
entered
these
lines
and
go
back
to
it
so
here
we're
going
to
copy
this
all
right
this
is
the
latest
version
of
repo
with
its
most
recent
bug
fixes
now
you
can
always
do
repo
init
u
and
get
the
master
branch
for
the
absolute
master
this
is
the
one
with
some
bug
fixes
but
if
you
do
dash
b
space
master
at
the
end
you
can
get
the
master
branch
okay
now
at
this
point
i
actually
went
with
the
master
branch
if
i'm
not
mistaken
but
either
or
you
know
you
probably
want
to
go
with
this
one
so
as
you
do
the
repo
once
it's
doing
its
job
basically
getting
all
of
the
repo
sources
it's
going
to
ask
if
you
want
to
enable
color
display
to
this
account
uh
just
hit
enter
and
eventually
it'll
say
repo
has
been
initialized
in
home
slash
that
comes
slash
moto
phone
now
at
this
point
you're
going
to
write
the
words
repo
sync
c
j12
so
dash
c
j12
is
important
if
you
do
this
if
you
basically
take
these
words
out
it's
going
to
take
even
longer
but
if
you
type
in
dash
c
and
j12
where
12
is
the
amount
of
threads
you
have
for
this
system
it
is
12
so
i'm
getting
it
i'm
giving
it
12
threads
i
think
it
could
be
11
or
12.
point
is
once
you
enter
this
it's
gonna
take
a
few
hours
to
potentially
a
day
because
this
is
downloading
over
a
hundred
gigabytes
of
source
code
and
even
on
gigabit
connection
it
takes
time
so
once
you
run
this
feel
free
to
walk
away
play
a
video
game
or
whatever
because
it's
not
going
to
be
done
in
a
few
minutes
it's
going
to
take
hours
to
a
day
i'm
telling
you
so
anyways
once
that's
done
all
right
uh
time
has
passed
all
right
i've
already
done
it
you've
noticed
that
i've
changed
to
droid
build
you
don't
need
to
do
that
i've
only
done
it
because
droid
build
is
the
directory
where
i've
already
downloaded
this
stuff
to
i'm
just
doing
it
for
the
sake
of
the
video
but
you're
probably
still
going
to
be
in
that
mooda
phone
directory
right
once
it's
all
downloaded
and
ready
to
go
so
the
next
thing
to
do
is
to
have
all
of
your
proprietary
binaries
now
this
is
where
i
said
not
every
device
could
be
modified
because
samsung
doesn't
give
its
proprietary
binaries
out
so
you
can't
build
aosp
on
it
you
also
can't
even
unlock
the
bootloader
as
far
as
i
know
now
certain
manufacturers
like
oneplus
or
whatever
will
give
you
those
binaries
but
we're
building
it
on
that
google
pixel
4a
so
we're
going
to
need
the
4a
binaries
now
at
this
point
what
we're
going
to
be
doing
is
we're
going
to
either
click
the
first
link
if
you
didn't
download
the
master
branch
like
we
talked
about
earlier
or
if
you
did
download
the
master
branch
they're
telling
you
to
use
the
binary
preview
now
i
use
the
master
branch
so
i'm
going
to
click
on
this
what
you
have
to
do
is
you
have
to
find
the
google
pixel
4a
and
ours
is
non
5g
so
it's
going
to
be
all
the
way
down
here
in
google
pixel
4a
which
is
the
4a
binaries
754367
okay
so
this
is
this
is
the
binary
that
we
need
again
if
you
bought
the
4a
with
the
5g
or
the
pixel
5
or
even
the
pixel
3
if
they
even
still
sell
that
you're
going
to
be
clicking
the
appropriate
one
for
you
so
in
our
case
we're
going
to
download
the
google
vendor
image
and
the
qualcomm
image
okay
so
we're
going
to
download
both
of
these
and
we're
going
to
save
those
files
so
now
in
the
moda
phone
directory
when
you
click
on
it
the
directory
you'll
be
working
in
i'm
clicking
on
droid
build
because
i've
already
done
it
you'll
see
all
these
folders
once
the
repo
has
been
downloaded
once
you've
gotten
the
source
code
what
you're
trying
to
do
is
you're
trying
to
get
those
vendor
proprietary
binaries
ready
for
when
we
build
because
without
those
we're
not
going
to
be
able
to
boot
android
on
that
4a
pixel
device
that
we
just
got
so
you're
going
to
basically
download
those
files
which
i
have
right
here
so
google's
devices
and
qcom
devices
so
you're
going
to
open
both
these
zip
files
and
you're
just
going
to
drag
them
into
this
folder
right
the
folder
that
we're
working
in
so
both
of
them
eventually
they'll
be
right
here
so
extract
google
and
extract
sunfish
so
in
order
to
do
this
now
we're
going
to
basically
run
these
scripts
because
these
are
dot
sh
shell
scripts
so
again
if
you
have
a
terminal
close
just
right
click
open
terminal
and
you're
going
to
type
dot
slash
extract
all
right
google
all
right
the
whole
thing
again
use
tab
to
autofill
save
yourself
some
time
and
insanity
hit
enter
and
it's
going
to
ask
you
the
license
will
now
be
displayed
so
hit
enter
and
blah
blah
blah
hold
space
down
and
eventually
get
to
this
bottom
line
so
type
in
i
accept
and
it's
going
to
install
all
of
these
to
vendor
slash
google
devices
so
in
this
little
folder
right
here
once
you've
done
that
do
the
exact
same
thing
for
the
qcom
sunfish
so
extract
qcom
sunfish.sh
hit
enter
hit
enter
hold
space
down
go
back
type
in
i
accept
in
all
caps
and
it'll
do
all
this
for
you
so
now
you've
extracted
all
those
proprietary
binaries
now
we
can
get
to
the
fun
stuff
which
is
actually
building
the
damn
thing
so
okay
now
in
the
build
system
it's
going
to
tell
you
about
the
soon
build
system
you
don't
really
need
to
know
a
whole
lot
of
this
let's
just
go
to
the
actual
build
android
side
okay
so
here
we're
going
to
be
running
a
couple
scripts
ourselves
so
go
back
to
our
build
folder
right
where
all
those
files
were
you
want
you
to
well
let
me
close
the
terminal
real
quick
right
click
open
a
terminal
and
inside
over
here
we're
going
to
be
typing
in
a
few
commands
all
right
and
it's
just
copy
and
pasting
so
let
me
show
you
what
we're
doing
so
in
order
to
do
this
what
we're
going
to
do
is
we're
going
to
build
our
source
all
right
so
we're
going
to
do
source
build
and
environment
setup.sh
so
hit
enter
and
it's
going
to
you
know
basically
set
up
our
environment
right
now
to
see
if
we're
actually
good
on
that
type
in
hmm
and
it's
going
to
show
you
all
of
this
okay
so
you're
good
so
far
type
in
clear
to
clear
all
of
this
out
and
let's
use
something
called
lunch
okay
so
when
we
type
in
lunch
all
right
lunch
gives
us
this
whole
list
real
quick
it's
going
to
take
a
little
bit
of
seconds
or
a
little
bit
of
time
but
it's
going
to
give
us
54
options
because
we're
installing
on
the
google
pixel
4a
we're
going
to
find
one
that
says
sunfish
so
you
see
how
we
have
aosp
rm64
this
would
be
number
27.
so
aosp
user
sorry
sunfish
user
debug
user
debug
basically
means
that
it's
the
standard
android
build
but
it's
already
rooted
anyways
which
means
you
get
all
the
elevated
privileges
again
please
look
up
based
on
what
pixel
device
you
bought
because
let's
say
you
bought
a
pixel
4
a
with
5g
you
might
be
redfin
you
might
be
something
for
the
base
4a
that
we
have
i
know
that
we
are
aosp
sunfish
so
once
you
know
that
your
number
27
type
in
number
27
here
and
hit
enter
and
it's
going
to
configure
this
all
right
the
target
right
here
so
make
sure
all
of
this
checks
out
for
you
and
once
it
does
let's
move
on
to
the
actual
fun
stuff
now
to
build
this
all
we
have
to
type
is
the
word
m
okay
it's
that
simple
hit
enter
and
now
we
get
to
the
magic
fun
stuff
of
actually
building
the
entire
thing
so
it's
going
to
run
something
called
ninja
and
whatnot
and
this
is
where
the
build
actually
begins
so
you
can
walk
away
for
a
few
hours
while
this
is
actually
doing
its
job
there's
not
much
you
can
do
okay
this
will
take
several
hours
a
few
hours
depending
on
how
fast
your
computer
is
and
whatnot
now
when
i
showed
you
earlier
why
i
got
52
gigs
of
storage
that's
literally
because
this
thing
crashed
with
32
gigs
of
ram
at
some
point
when
it
was
building
its
neural
engine
neural
network
stuff
whatever
that
project
file
was
it
apparently
ballooned
memory
usage
to
like
32
gigs
it
started
using
the
swap
space
which
is
an
entirely
separate
range
of
like
memory
that
you
rely
and
back
up
on
crash
that
so
provided
you
followed
all
the
steps
up
until
this
point
you're
good
to
go
walk
away
you
know
get
a
coffee
you
know
have
some
beers
play
some
video
games
because
it
ain't
going
to
be
done
for
a
while
now
if
we
haven't
actually
done
anything
yet
we
need
to
make
sure
usb
access
works
okay
so
underneath
this
page
for
the
android
developers
we're
going
to
make
sure
that
our
ubuntu
linux
device
works
absolutely
well
so
what
you're
going
to
do
is
you're
going
to
go
down
over
here
and
you're
going
to
copy
sudo
user
mod
a
capital
g
plug
dev
into
the
log
name
okay
so
just
paste
that
in
there
hit
enter
enter
your
root
password
all
right
is
it
working
there
it
is
it
works
and
after
all
that
you're
going
to
basically
uh
just
do
apt
pseudo
install
so
again
just
do
sudo
and
copy
that
string
in
here
and
hit
enter
and
install
that
now
you
should
just
re-log
in
for
all
of
this
to
actually
take
effect
but
once
it's
done
you're
ready
to
move
on
to
the
next
step
okay
now
at
this
point
to
flash
the
device
what
you
want
to
do
is
you
want
to
make
sure
that
you
follow
these
combinations
so
turn
off
your
google
device
so
for
example
the
4a
that
we
have
we're
going
to
first
power
off
the
device
so
we're
going
to
power
it
off
like
this
all
right
and
here
it
tells
us
to
hold
volume
down
and
hold
the
power
button
so
if
i
hold
volume
down
and
hold
the
power
button
this
should
boot
into
yeah
right
here
so
fastboot
okay
this
is
basically
the
screen
you
want
to
see
on
your
google
pixel
4a
so
at
this
point
what
you
want
to
do
is
you
want
to
connect
it
to
the
actual
device
you
want
to
connect
it
via
usb
to
your
virtual
machine
under
vmware
it's
probably
going
to
ask
you
if
you
want
to
connect
to
the
host
or
a
virtual
machine
always
pick
virtual
machine
and
make
sure
you
check
it
so
that
it
doesn't
even
have
to
ask
you
it
again
okay
just
to
save
yourself
some
time
and
sanity
now
you're
going
to
type
in
fastboot
flashing
unlock
okay
so
once
you
type
that
in
it'll
basically
change
this
screen
and
it'll
ask
you
do
you
want
to
unlock
the
bootloader
now
you
actually
have
to
use
the
volume
keys
to
make
the
selection
but
you
want
to
hit
yes
and
once
that's
done
it's
time
for
you
to
actually
start
flashing
the
device
now
at
this
point
it's
going
to
delete
everything
off
the
device
so
if
you
were
using
it
to
store
all
your
personal
stuff
for
some
reason
before
doing
all
this
you
want
to
back
that
up
because
this
is
going
to
flash
the
device
entirely
so
once
you
have
it
basically
connected
into
your
system
you
want
to
make
sure
you
type
in
adb
reboot
boot
loader
okay
and
the
reason
you're
going
to
do
that
is
so
that
you
can
actually
get
into
the
bootloader
and
once
that's
all
good
to
go
in
fastboot
which
is
where
we
were
at
this
screen
all
right
this
one
right
here
you're
going
to
type
in
fastboot
flash
all
dash
w
alright
so
at
this
point
all
right
if
the
device
is
connected
do
not
touch
it
it
will
do
it
all
for
you
this
is
where
it's
going
to
send
that
built
android
that
we
have
and
flash
it
onto
the
device
okay
so
provided
you
did
everything
right
it
should
all
just
flash
up
perfectly
fine
and
you're
good
to
go
and
there
you
go
the
muda
phone
is
finally
ready
to
use
now
it's
not
really
the
mooda
phone
it's
whatever
you
want
it
to
be
called
baby
because
you
built
it
yourself
congratulations
you
built
android
and
deployed
it
on
your
own
device
you're
a
good
job
it's
that
easy
okay
we
did
this
within
30
minutes
all
right
again
discounting
for
the
amount
of
hours
we
lost
so
if
you
have
a
powerful
enough
system
you
just
built
your
own
os
and
you
know
it's
squeaky
clean
it's
got
no
google
to
it
see
this
is
android
in
its
purest
form
all
the
google
stuff
fails
to
work
because
the
apis
just
aren't
there
this
is
what
android
is
like
without
google
now
of
course
this
comes
with
its
own
problems
google
does
provide
a
lot
of
good
back-end
api
stuff
to
android
it
makes
it
really
fun
and
easy
to
use
but
if
you
remove
all
that
it's
not
that
android
is
unusable
it's
just
you're
gonna
be
missing
a
lot
of
that
magic
okay
so
you
do
get
a
little
bit
of
an
inconvenient
system
but
hey
it's
all
yours
nobody's
tracking
you
congratulations
you're
innocent
and
safe
now
if
you
want
to
re-implement
google's
proprietary
user
space
apps
and
libraries
you
can
use
this
thing
called
micro
g
which
i
think
actually
comes
from
the
lineage
os
people
and
basically
all
you
have
to
do
is
really
download
a
lot
of
these
apks
and
install
them
onto
the
device
okay
basically
just
connect
this
to
a
usb
to
your
computer
drag
and
drop
these
apks
open
the
file
app
and
install
them
one
by
one
and
follow
the
on-screen
instructions
and
you're
good
to
go
now
as
far
as
app
stores
go
there's
plenty
of
app
stores
for
you
to
pick
from
so
pick
your
poison
download
it
uh
some
of
them
even
belong
to
amazon
or
samsung
so
you
know
you
can
still
have
the
big
tech
you
in
in
your
device
if
you
wanted
it
as
far
as
the
applications
go
there's
a
few
app
stores
that
you
can
download
and
get
running
some
of
them
belong
to
amazon
some
of
them
are
as
free
as
the
ratchetest
river
that
you
can
find
and
ladies
and
gentlemen
once
you
get
the
stuff
installed
you
can
basically
install
all
of
those
freedom
phone
applications
like
parlor
like
brave
like
firefox
like
whatever
you
want
on
your
device
now
you've
effectively
got
your
own
freedom
phone
congratulations
now
i'm
not
going
to
say
that
this
is
unusable
it's
absolutely
a
very
usable
phone
there's
nothing
wrong
with
using
android
this
way
but
like
i
said
earlier
without
google
you
are
going
to
have
to
come
across
a
little
bit
of
an
inconvenient
use
okay
it's
going
to
take
a
bit
of
time
to
truly
um
settle
in
okay
you're
gonna
have
to
break
this
device
in
your
own
way
i
think
the
best
comparison
is
kind
of
like
linux
we're
using
ubuntu
which
is
very
user
friendly
anybody
can
get
those
going
even
your
grandma
and
then
you've
got
arch
linux
and
gen2
which
are
more
so
for
people
who
are
really
there
to
build
their
own
experience
and
if
you
can
handle
all
the
technical
hurdles
and
the
headaches
that
come
with
it
it's
absolutely
a
great
choice
but
this
is
android
without
google
and
this
is
effectively
the
same
thing
as
that
freedom
phone
that
you're
getting
now
let's
say
you
don't
want
to
go
through
all
that
effort
okay
let's
say
you
want
to
make
this
life
even
easier
for
you
this
is
lineage
os
okay
something
that
i
actually
used
to
use
for
a
long
time
and
it's
actively
being
updated
all
right
last
update
last
change
log
was
april
1st
2021
so
here
you
go
on
to
download
and
you
got
a
whole
range
of
devices
they
constantly
build
for
so
if
you
have
something
like
a
asus
rogue
phone
you
can
go
for
that
if
you
have
a
uh
what
is
i
think
i
saw
razer
right
here
you
can
go
for
that
if
you
have
an
older
samsung
device
before
they
decided
to
get
real
douchey
with
their
bootloader
you
can
pick
some
of
those
now
if
you
have
a
google
device
you
can
go
to
google
and
you
can
go
get
the
google
pixel
4a
this
takes
you
to
this
page
what
you
want
to
do
is
you
want
to
download
the
latest
both
these
files
and
you
want
to
click
installation
instructions
and
basically
follow
this
down
to
a
t
and
it's
not
too
different
than
what
we
just
did
except
this
one's
a
bit
curated
by
a
team
again
you're
still
going
to
be
detached
from
google
so
they're
not
going
to
be
pinging
your
location
that
is
until
you
install
the
google
apps
but
that
puts
you
in
the
same
position
as
having
google
stock
android
running
on
its
own
why
the
you
would
go
down
that
road
why
would
you
would
go
through
this
trouble
and
then
reinstall
the
google
apps
makes
no
sense
to
me
but
some
people
do
it
and
hey
who
am
i
to
tell
you
how
to
live
your
life
right
ladies
and
gentlemen
let's
recap
this
is
a
long
video
already
my
recording's
looking
at
like
an
hour
and
a
half
but
uh
ladies
and
gentlemen
what
have
we
learned
today
okay
you
don't
need
to
pay
somebody
500
to
get
a
freedom
focused
privacy
phone
okay
they're
just
grifting
off
you
most
likely
they're
trying
to
sell
you
a
phone
that's
very
cheap
with
a
lineage
os
rom
probably
installed
onto
it
i
mean
even
one
of
the
features
they
have
called
trust
actually
was
a
built-in
feature
for
lineage
os
so
make
that
what
you
will
but
uh
why
we
did
this
was
that
you
can
buy
yourself
a
better
quality
device
and
i
can
almost
assuredly
tell
you
these
pixel
devices
are
probably
a
lot
better
than
whatever
anybody's
trying
to
sell
you
from
any
other
part
of
the
world
okay
and
you
don't
even
need
a
pixel
device
you
can
literally
buy
yourself
something
from
one
plus
something
from
asus
something
from
a
bigger
better
brand
for
the
same
price
if
you're
going
to
spend
500
spend
it
on
the
best
hardware
that
that
money
is
going
to
get
you
because
a
software
as
you've
seen
is
actually
quite
easy
to
get
going
i
mean
it's
not
like
you
need
a
whole
lot
even
if
you
don't
want
to
build
it
there's
plenty
of
roms
that
exist
already
built
for
you
that
you
can
just
download
within
a
minute
and
already
start
flashing
on
a
device
through
a
virtual
machine
this
whole
process
if
you're
using
something
like
lineage
os
could
have
taken
you
15
minutes
to
do
on
your
own
building
the
whole
android
source
like
we
did
was
the
real
meat
and
potatoes
of
truly
doing
all
of
this
on
your
own
and
that
if
you
have
the
most
powerful
hardware
available
right
now
is
only
a
matter
of
a
few
hours
just
to
download
and
build
the
damn
thing
it's
not
the
technic
it's
not
the
most
technically
advanced
thing
to
do
the
reason
why
after
that
original
product
the
freedom
phone
was
that
the
device
you're
getting
at
least
to
me
looks
like
it's
not
the
best
quality
and
the
software
side
of
it
is
something
that
anybody
could
have
done
within
20
minutes
do
not
discount
your
talents
if
you
think
you
are
technically
illiterate
don't
worry
if
a
dumbass
like
me
could
do
it
bro
you
could
do
it
a
lot
better
i'm
just
saying
okay
so
ladies
and
gentlemen
we
built
our
own
freedom
phone
our
mood
os
or
at
this
point
it's
whatever
os
you
want
it
to
be
hell
call
it
the
whatever
your
name
is
and
then
add
os
at
the
end
of
it
and
bam
you're
done
so
that's
pretty
much
how
you
do

hi what is a brushed DC motor it's a motor that runs on DC voltage how to drive it you just stick it to a DC voltage okay hey Khan your sheet shaft I said calm your shaft what you have to keep it exists everywhere from your hairdryer yes it's a DC motor they pass the AC through the heater element to drop the voltage and then pass it through a full bridge rectifier to give it to the model the existing cordless drills although some drills have brushless DC motors but that's another story and they exist in fans and toys and drones and vibrators of your mobile phones let's make a simple one first I want to make this state or the stationary part of the motor out of these plastic old CD covers I just cut some walls out of it then we glue the walls together they're a tiny little stator box then we need two permanent magnets with North on one side and South on the other side then we just glue the magnet north in on one side and South in on the other side like this then we just poke two holes right between the magnets on the walls not to make the rotor they're part of the motor that rotates we take a nail and cut the end off then we take some steel wire and twist it around the nail to shape a cross something like this a little bit off-center and the same length on both sides now we get some magnet wire which is basically coated copper wire and we can get this from old wall adapters and wrap it always in the same direction around the steel wire [Music] so we make something like this then we remove the coating from the end of the wires then we place the nail in the holes of our stator now you see if I pass electricity through the coil it tries to array align itself if I can grab it okay see it tries to realign itself with the magnetic fields and rotate now we put some electric tape on the nail to isolate it move the wires to a location perpendicular to the coil and cut the extra pieces and remove their coating now we need to make something called a commutator which is just contacts to these wires and brushes that will touch them I made my rotor too small maybe you want to make yours a little bit larger so it's easier to work with for the contacts I need something rugged so I'm gonna cut the metal off of this food can I have to sand the surface to expose the conductive metal I can even solder my wires to them very well not bad eh okay the moment of truth I'm connecting my power supply using these wires as brushes over my commutator or let's see if it turns [Music] success see how much ARC's are flying off of the commutator the amount of heat and current is damaging my contacts and blues I should have made it better but the commutator and brushes are the downside of brushed DC motors this is an actual rotor I took from a small motor and can work in the same setup there we go no what do you know design much better than my rotor they don't make to pole roll towards anyway it's always three and above now there are tons of different motor designs and you have to pick one for your actually the proper torque depending on your room to use gears to increase your select what RPM the motor should grow you need to study torque and speed limited by the space and weight in your design and maximum voltage and current is typically stronger turning one way than the other what I'm trying to say is that there are a bunch of mechanical considerations to pick a proper motor and you let your mechanical engineer minions to take care of those low level stuff you are here to drive it now there are a bunch of challenges driving any motor which is typically at startup and shutdown and during the operation so let's see what they are but a lot of what I'll say applies to all electric motors the brushes and contacts of a motor which is called the commutator is an interesting arrangement if you think about it it converts the DC input to AC over the coil because as the rotor turns it flips the polarity over the coil if we turn the motor manually if we generate electricity simply because we are moving the rotor coils through magnetic fields this generates AC over the coils say around hundred Hertz but the commutator rectifies it at the input and if you look closely you will see that I have a brand new four channel keysight scope they just came up with this scope this is the new brother of our sister I mean I'm not sure I don't want to assume it's gender the new model of my to Channel school it has all the great features of my beloved school comes in Batman black 4 channel 2 megahertz and I'll give away four of these at the end of the video you can sign up from the link in the description which also puts you in keysight's wave 2019 equipment giveaway which happens in March more detail at the end now I'm going to spit out a ton of information around DC motor drive it is guaranteed to hurt your brain so save yourselves or buckle up so a motor with permanent magnets acts as a generator to outputting a bumpy voltage but even when we run it from a power supply that generation action still happens and creates electromotive force or voltage that comes back from the motor that we call back EMF a simplified model of the motor winding looks like this the inductance of the winding in series with the resistance of the wires in series with an AC source for back EMF this regenerative voltage source exists on all the windings of the rotor and it's voltage is dependent on the speed of the motor starting from zero when the motor is not turning and goes up by speed all the way close to the supply voltage the back EMF sources of different windings get rectified through the commutator similar to a three-phase even fuller bridge rectifier and create a bumpy DC source so you can model the DC motor at the supply lines like this the inductance of the winding series with the total resistance of the motor series with a rough DC voltage supply now here's the interesting part for a well-made and lubricated motor we expect a small input current when no load is attached to the motor it is because when we start a motor and it speeds up the back EMF voltage Rises close to the supply voltage creating a small voltage drop across the motor resistance which means small current draw the winding inductance is short circuit for DC but as you load the motor it slows down and so the back EMF voltage drops causing a higher voltage across resistance or higher current draw the higher current results in a stronger magnetic field and so the motor turns with a stronger torque to keep up with the load this is why if the motor ceases to rotate it can burn because the back EMF drops to zero and the entire supply voltage falls across there is store knowing all these let's start a motor using a battery and measure the current on the scope see the current spikes to around 80 amps even for this tiny motor and then drops to around 3 amps it is because at the beginning there is no back EMF to lower the current and the current drops as the back EMF Rises with the rise of the motor speed they call this initial spark the inrush current motors like engine starters draw over 200 amps of inrush we had a motor at work that would draw over 800 amps of inrush this imposes a huge startup challenge for systems that can't handle this much current you might say the motor has a series inductor that should limit the current know the electrical time constant being L over R is very small in milliseconds much smaller than the mechanical time constant so the current jumps to maximum which is the supply voltage divided by resistance very quickly around 2 milliseconds here before the motor has time to speed up and lower the current over 100 milliseconds here now let's turn off the motor and look at it voltage look at that I turn off the motor around here then it's kind of flat for around 6 microseconds then there is a huge negative spike of over hundred volts the reason it's flat at the beginning is that when I disconnect the wires there is a tiny arch between them for a few microseconds that limits the motor voltage but as soon as the arc goes away BAM there's a huge voltage spike when we discharge an inductive load like a motor they induct hands energy discharges creating a large negative voltage spike that can create an arc across the contacts this arc momentarily shorts the discharge energy this initially limits the voltage across the motor but when the arc goes away the voltage jumps to minus hundred volts as we saw if there was no arc the voltage would jump thousands of volts without protection any circuit would blow up this is one of the main reasons that the commutator brushes get burned and wear away the main downside of brushed DC motors because when those brushes switch around there will be high temperature arcs between the contacts that wear them away if we look at the shutdown voltage again over a longer period you see after the negative inductive spark the voltage returns positive and declines slowly this is the back EMF at work the motor hasn't stopped yet as it has momentum the fuzzy noise is due to commutator switching so the back EMF voltage goes down as the motor stops this can cause us trouble later or we can suck the back EMF energy out and use it which would result in the motor stopping faster that's called regenerative braking now I'm running the motor from my power supply measuring the current and if I short the contact see it draws around 70 amps from the motor sucking the back EMF energy I'm stopping the motor quickly ok so there are problems driving motors let's calm down and try to solve them first the high voltage spike at shutdown it's a simple one as a good solution we can just add a reverse diode across the motor this diode is called the flyback or freewheeling diode when we run the motor that diode is off but when we disconnect the motor and the voltage of the motor flips the diode turns on and the current loops through the diode for the short time constant of the inductor so the reverse voltage across the motor will be limited to the diode voltage around minus 1 volt and after the inductive energy goes away the back EMF kicks in hmm let's try it I put a diode across the motor contacts and if I turn it on my diode blew up it was in Reverse so in this method we can only run the motor in one direction trying again I turn it off and you see the voltage only goes negative a little bit there are no arcs and the voltage rises back up due to back EMF ok one problem solved now how do we help the large start of inrush current one good solution would be to raise the supply voltage slowly to have a limited current while the motor Rams stop and that's exactly what we do we limit the supply applied to the motor using PWM or pulse width modulation imagine we have a switch and we turn it on and off quickly at a fixed frequency initially we get a short on time so the motor has time to ramp up and we increase the on time until it reaches the maximum speed the switches we use in our circuits are fast in channel MOSFET transistors because they have a very small on resistance and wastes little power I'm not going to talk about MOSFETs on how to drive them properly that's a whole other topic if we turn on the motor straight up the inrush current rises to maximum with the time constant of L over R then drops slowly as the motor ramps up first off your initial pwm on time should be shorter than this rise time which is in mini seconds otherwise the current reaches maximum and it defeats the purpose now picking up the PWM frequency is important for best control the PWM period should be shorter than this inductive rise or fall time say smaller than three time constants and that's me talking from experience it might be written somewhere more formally let me explain imagine the motor is running and we have this voltage across it then we turn it off we have the negative inductive kick clamped by the diode and then the back EMF if the pwm goes on during the back EMF we are letting some of the back EMF during the off time then the voltage goes back up and the cycle continues this means that the motor current drops to zero every cycle this results in an unpredictable voltage across the motor because this regeneration voltage depends on speed and rpm and things so for better control we pick a higher frequency to keep this voltage out this way the motor voltage would be nice and square with its average equal to the duty cycle times the supply voltage and the motor current would be a nice ripple e DC equal to the supply current average divided by the duty cycle here I have a MOSFET transistor series with my motor and I'm driving its gate from my function generator and I'm measuring the motor voltage and PWM input I'm running the PWM at 50% and you see if I change the frequency it doesn't affect the speed of the motor until I lower it so far that the regeneration voltage gets into the off time you see the motor is running faster with the same TWM this additional back here voltage is raising the average voltage across the motor which also changes by load and speed that's why we keep the frequency higher to keep the voltage across the motor constant for better control now you see changing the pwm can nicely change their speed and this is how we manage the inrush current by controlling the motors of life instead of turning the motor dead on we PWM it on and off and control the current until it hits the curve we want we can control it to completely remove the inrush or allow some acceptable inrush to get in if you raise the current slowly the motor ramps up slowly so in some application that we need a more responsive motor we allow some inrush currents so that the motor can kick on faster now let me show you some current plots the motor draws current from the supply in the on time and loops the current through the diode in the off time so the supply current is the same as the motor in the on time and zero in the off time which is the same as the transistor current and the diode current is zero in the on time and the same as the motor current in the off time now this is important we have to pick our components so that they can handle this current also you see that we are switching large currents through the supply and diodes so the electromagnetic radiations become an issue filtering for those is a whole other issue I won't discuss here are you tired yet but wait there's more so far we have been driving the motor through a puny single transistor it's time for a half bridge driver see running the current through the diode wastes some good power so if instead we replace it with a low on resistance transistor we could save much more power like with this toggle switch I can switch it on and off but I guess I can switch it at kilohertz frequency remember when switching the motor voltage with the flyback diode at low frequency PWM the back EMF voltage would get in during the off time because the diode would turn off but if we replace the diode with a switch like I did or a MOSFET it won't turn off shorting the back EMF voltage and breaking the motor so this is important when using a half bridge the PWM frequency must be fast faster than the inductive discharge time otherwise you will stop the motor every cycle now let me turn on the motor using my half bridge if I can turn on the PWM that's know clearly at the moment I don't have the means to drive the half bridge an important thing running a half bridge is that the two switches must never turn on at the same time otherwise they'll short the power supply a huge current will shoot through them and they'll blow up the control signals must be such that one transistor turns off before the other one turns on and for safety we keep a time gap between them called a dead time during which both transistors are off for better control though we want that time to be as short as safely possible you might ask if both transistors are off at the same time then what will absorb that high voltage inductive kick well the good thing about MOSFETs is that they naturally have these internal diodes that do the job so let's see what happens when we PWM the motor the motor can connect to the ground or positive doesn't make a difference in control first the top FET is on and the current flows through the motor and the motor voltage is positive then the top FET turns off and the motor current runs through the body diode of the lower FETs and the motor voltage drops below ground for the short period of dead time until the low FET turns on and the current runs through it then the low FET turns off and the current runs through the body diode again until we turn the top FET on this is what you see if you probe the motor voltage so at start off we ramp up the PWM duty cycle to limit the inrush current and it's powered down we can just turn off the switch s and let the motor stop on its own or ramp down the duty cycle if we ramp down the duty cycle faster than the National motor slow down rate this act will suck the back EMF energy from the motor and force it to slow down faster by pumping current back into the power supply you can use this current to charge a battery as in regenerative braking what if you don't have a battery or supplier to absorb this current it will push your supply voltage high probably too high and kills all your circuits this has have before the easiest solution in this case is to turn off all the switches when a high voltage is detected and stopped pumping the current I think we took care of everything but no so using a half bridge you can change the duty cycle to change the energy input to the motor and control the speed but not the direction that's why we put two half bridge drivers together to make a full bridge driver which they also call an H bridge because it looks like an H there are four switches and the motor connects between the two halves if you turn these two switches on the motor turns one way and if you turn these two on the motor turns the other way there are different ways to drive an H bridge but for example we can turn this off and that on continuously and PWM these two for one direction or turn this off and that on continuously and PWM this one for the opposite direction I think we successfully scratched the surface of how to drive brushless DC motors there's not much left the rest would be how to choose transistors problems right the switches properly features to expect from a driver I

[Music] welcome back to China uncensored I'm Chris Chappell this episode isn't sponsored by surf shark protect your privacy online now my team of high-powered market researchers has told me I need to make China uncensored more appealing to Generation Z and that's why I joined the tik-tok it's just exactly fine tick tock tick tock has 500 million active users worldwide and including pretty much everyone under 25 it's fire weird flex but ok why are you how do you even get in here okay boomer look I get that tick tock is the coolest new app or Lidice or most goo chief am i hate myself right now but the biggest problem other than my own looming mortality is that tick tock is owned by a Chinese company back in 2017 a Chinese company called byte dance bought the social media app musically for close to 1 billion dollars musically was based in Shanghai but most users were in the US where it caught on with American teens then they merged music leads user base into tick tock and that allowed them to slide tick-tock into the US market now you might think so what if tick tock is owned by a Chinese company well if you're worried about FBI man watching you you should be way more concerned about MSS man watching you MSS is China's Ministry of State Security they're seriously scary dudes or whatever Zoomer is called dudes these days and China has very different laws about data privacy namely in China there's no privacy Chinese law says Chinese companies that collect user data have to share that data with the Chinese government upon request it's not the Chinese authorities actively monitor every users data in real time but the reality is that if and when Beijing makes a demand it's hard for Chinese based companies to say no and that's why it might be concerning that a Chinese company buy dance owns tik-tok since tik-tok collects so much user data that data includes your user name what you like where you are in the world what's being recorded by your camera and microphone etc and it's not just me speculating about security risks the US government has just opened a national security investigation into tick-tock the investigation is led by Sophia's the committee on foreign investment in the United States Sophia's is an interdepartmental group of federal government agencies it investigates and sometimes blocks deals by foreign companies that might pose a risk to US national security for example last year cepheus blocked Chinese owned and financial from buying financial services company MoneyGram Sophia's also blocked IDG energy investment from buying a bunch of oil and gas assets in Texas and now cepheus is forcing a Chinese company to sell Grindr a gay dating app Chinese gaming company Kunlun tech had purchased Grindr last year without going through Sophia's review Sophia's didn't disclose specifically why the Chinese buy out of Grindr was a national security concern but I can just imagine what would happen if the Chinese intelligence service knew private information about Americans like who's gay who's hiv-positive and had access to the pics that may occasionally get sent by men using the grinder app imagine all the blackmail opportunities anyway back to tik-tok earlier this year there were also some concerns about tick-tocks censorship it came after the Guardian got its hands on tik toks content moderation policy each show tik-tok had been censoring content that was embarrassing to the Chinese regime for example there were reports that videos about the Hong Kong protests were either blocked completely or quietly labeled as viz able to self so other users couldn't see them and this apply to the American app tik-tok not the Chinese version which goes by a different name but it seems that since May this year tik-tok has changed its policies to distance itself from Beijing tick tock now claims that it does not censor content while also not specifically admitting that they ever did in an official statement tick tock said their data centers are located entirely outside of China and none of their data is subject to Chinese law they also said they have never been asked by the Chinese government to remove any content and they would not do so if asked which is funny because bite dance the company that owns tick tock is completely governed by Chinese law that means the Chinese government could in theory require bike dance to require tick tock to give up user information which means tick tock would give it to bite dance which would give it to the Chinese government but I see no reason why the US government should ban a Chinese own social media app even though the Chinese government bans pretty much all American social media apps like Twitter and Facebook but still sophia's is investigating tick tock as a potential national security risk cepheus just won't reveal why since they do not comment on information relating to specific cases there are a few things that could happen after this review process sophia's could decide tick tock is a risk and ban it outright that's unlikely Cepheus could decide that tick tocks owner bike dance needs to sell off tick talked to an american company that's what happened with Grindr although the difference is that tick tock wasn't an American company to begin with or see if he's good to side there is no problem and then tick tock would be free to do whatever tick tock does because frankly I still don't get the appeal what are you still doing here anyway this episode has been sponsored by surf sharp you should be using a VPN
