wow that is actually i know it vibrates
in your head so is this this is it
didn't sound right this is more on yeah
okay you have two i am i am actually
trying to learn here and i
i've learned a few valuable things so
far like you can't have enough blocks
it's one of them yeah so here's the
thing paul will use this amount of flux
like this right right this is paul
that's okay this is proper
okay got it
it didn't have fan spin you put your
soldering iron to the board it had fan
spinning all right everybody you're in
for a treat today we got somebody here
from north carolina to do a board repair
that's right i'm
i've never actually done any kind of
repair i've only made things worse well
there's one there's a place to start
sorry here we are sir all right all
right so what is what's the story of the
board what do i know about what do you
see let's see i'll switch over to
overhead i see red i see oh there you go
that's a good shot
so i see some of uh let's point with
this
whatever that is
either
either a um
high c like you know the fruit drink
yeah or
something else i don't know
uh
that looks like
maybe that's wi-fi card that's optional
no but i mean like the do you see that
right yeah the red stuff that mud or
what
it's from a construction site
that looks like the sticker stuff leaked
off okay that's wi-fi they don't need
wi-fi they can use ethernet they have a
dongle for that um
that's corroded by the screen area yeah
so that's going to cause no backlight
this is corrosion by a circuit that may
that's a power circuit that's going to
create the main power rail that starts
the computer turning on that i actually
don't know off the top of my head what
it is
which one
where would you start on this so you
have you have corrosion
on the wi-fi card the screen and a power
rail where would i start it yes i would
start with a new board
isn't that cheaper i don't know
so you think let's give everyone a
perspective i guess
from
so if you looked at this
if you had the rough estimate how long
it's gonna how long are you gonna stare
at this thing before you fix it it's
like 15 minutes 15 minutes okay so
everyone i want to remember that for
when lewis has to come in and fix it
because it takes me an hour to do one
thing so first thing we have to do is
come up with an order of operations so
you have some corrosion on here you have
corrosion by the screen
wi-fi card and a power rail right which
one is the one that you would address
first i feel like the power rail is
yeah it's maslov's hierarchy it's
maslov's hierarchy of needs so first you
need to turn on then you need a screen
then you need internet right right so
so power rail so that's the power rail
and then what did you say these
that's for the screen that's for the
backlight those caps are white they
could use a flashlight they don't yeah
those are capacitors okay so what we're
gonna do is switch over to microscope
have you used a microscope before
uh sort of yeah all right this is gonna
be fun not competently i have used one
we have a similar setup not as not as
nice but okay
so you're gonna move this to where your
eyes are however your eyes are now the
beauty of this
is 90 of this job
yeah is flux
and hot air it's kind of like being a
janitor like it's not you know it's just
like clean up an aisle yeah okay yeah so
this is kind of like you're mr clean
over here so this sure this is kind of
like like bleach
and then this is your mop okay you just
kind of point it at the area and see the
sea should start to melt
right right yeah okay
um so what uh
how do you choose between flux and hot
air what's your i want to make this
clear for
everyone on whoever's watching too like
this i i was telling luis i don't have
much soldering or board repair or any
kind of experience like even working
with flux
not much so there's two things to know
so i'm looking forward to it the first
is you can never use too much of this
okay there's no such thing as too much
of this it'll always just burn away so
you could literally just pile it on that
seems to disagree with you earlier on he
seems like seems like he thinks you
maybe use a little too much we're polar
opposites in that particular area you
can never use too much flux okay and
then once you have the flux on there
you're going to heat the board from far
away like this got it but yeah
and then get a little closer and then
get a little closer and then get closer
stay there for a bit once you see that
it's melted take it away okay and then
we'll see if it turns on got it so the
first thing i need to do is get you a
flux container that has the proper
amount of flux because that that that
that that's barely anything so a lot
yeah you it you need this and we're
planning to use all of this right a good
amount of it no we're going to use all
of that you said
he said it's only only good if it's
we're going to get along really well
here all right so
now this is the hot air station over
here so every time you put the hot air
back in here it's going to
cool down and then when you take it out
it's going to turn on okay
so
if you don't burn this keyboard i will
consider today a win
you already push the keyboard back
that you should push the keyboard i hate
that thing it makes so much [ __ ]
noise so if you burn it it actually
would be a window
i can't stand those mechanical keyboards
that go to the clickity clack so i don't
know
how well they can hear you now that uh
the thing's running the the fume i guess
that's the fume extractor
yeah
all right so
let me look at this closer
am i targeting
sort of that area right there yeah okay
so what we want to do is do we care
about that dot
uh up at those two caps or there's
mlcc's right there which dot uh right
here that looks like liquid or glue or
something oh that's that's embedded the
water can't get under there so that
that's some like some uh protective
bubble thing that
they put over those two caps
yeah okay
uh
well
let me test
what's the second i'm getting out of
water
[Music]
okay we're gonna lewis has has abandoned
me
i don't know what i'm doing
so i don't know what his stream setup is
it sounds he was telling me that he's um
recording himself on his mic and then
he's gonna i guess edit it and put it up
on his youtube channel later
so you said they can't hear you right
now right on your mic you can only hear
me through yours okay is that too much
what what are you thinking that's not
enough it's too much
okay lewis is that's that's not that
right that's how i apply thermal paste
yes that's okay got it
supplied flux the way apple applies
thermal paste okay okay got it i can
definitely all you had to say was do it
like you apply thermal phase and i would
have been on board so am i switching to
the yeah so now hot air yeah okay so
pull it up does it automatically turn on
yep that thing automatically goes on you
hear it all right and this is where it
shows you what the temperature is over
here it's going to go up to 500 degrees
in a moment is that a c yeah
there we go
and what's what's my objective right now
mel the like so see this watershed over
here we're waiting for this whole blob
to look like a giant thing of water
farther away closer is that what you do
you're gonna do is first you're gonna
preheat the board before you can
actually heat the chips so if you put
500 celsius on the chip you're not
really going to it's
500 celsius right on the chip the board
is cold so the board is going to absorb
all the heat so you're not melting the
solder and the chip itself is going to
burn so you want to slowly get the board
preheated from a little further away so
is this any kind of distance right a
little too far too far a little closer
in there okay a little closer in there
lewis has advised me that there's
nothing i can screw up that he can't fix
and uh
i hope he's right i mean paul by that he
says he means paul by the head
all right now see over here you see this
like you see a solder joint but then you
see that this is just the pile of [ __ ]
over here yeah yeah on the bottom of the
chip right when you reflow when this
gets reflowed that's going to go away
and also make sure that the nozzle is
pointing right at that chip
specifically the black this little black
rectangle got it okay and then go closer
in on how close right here i would say
even a little bit closer than that okay
and have it there for about 10 seconds
three four five six seven eight nine ten
should i stop
yep okay now take it away all right
socket it
and now it's going to cool off now that
right now the air is running through it
but the heater is turned off so that
this doesn't boil and burn got it okay
now the next up is going to be kind of
like filing your nails so the way i like
to describe it
these are kind of like your nails over
here okay lewis is right to re-repair
this board hey have some confidence in
him jim
this isn't australia we do [ __ ] right
here
so
australian currency so it's going to be
this iron over here
as uh
all these irons that i have have special
tips that looks diff so this iron is
shaped like a knife okay let's see if i
can get it on the screen for
dirty can you all hear lewis okay right
now they'll hear me in the in the
recorded version nobody watches the live
channel anyway okay well they might be
because i tweeted it but oh [ __ ] yeah
okay [ __ ]
so this see see how this is shaped like
a knife you're going to kind of want to
be adding solder but kind of like filing
your nails like back and forth over here
so the whole idea is to reflow these
joints in the bottom right that look
like [ __ ] got it so what um
sorry are you joining now again are you
i want to see you at the right amount of
flush
don't do that [ __ ] is it
a how much are you scraping with this
versus just running across that just
gently like this just across yeah okay
so don't dig in other words yeah we're
not digging we want to be making contact
on those joints is uh you want the same
amount of flux as you did a minute ago
or should i use that that's that's
that's a little sufficient that's good
now you're going to go back and forth
but while adding solder and here's the
thing the excess solder that you're
adding is going to go up on there okay
and then after the excess solder that's
up on there you're going to clean it off
and this little uh and that thing over
there
at home do you use a sponge or do you
have one of those little things yeah
yeah the sponge never works right okay
so
first step am i just going across it
without the solder uh
while adding solder while adding some
hair okay
so using the
the scope versus looking at it you're
going to want to use the microscope you
have to get it yeah so before you even
use the iron i want you to get used to
looking inside the microphone okay yeah
i'm i'm over here looking at the screen
so
looking at the screen will [ __ ] up your
head i did that in the beginning yeah
this is the chip i'm working on right
the worst thing you could that can
happen here is you kill an apple product
and honestly that's i'm okay with that
so that is the chip right uh-huh okay
and the left leg is good but the three
right legs are covered in that corrosion
corroded [ __ ] got it okay
so what am i don't be afraid go for it
go for it run for it
yeah all right all right i'll do that
again all right and just going back and
forth like filing your nails
we're stuck
we'll move the board up a little bit so
that's easier for them to see in them oh
sure go for it there you go you want me
to demonstrate the idea on the donut
that would be great yeah let me show you
the idea that would actually be the
proper thing to do here
i'm a schmuck of the teacher so so let's
say we have
okay so let's say i'm looking at the
right side of this chip sure you're
gonna do something like
this
okay
make contact and it's kind of like
filing your nails
how do you deal with the blobs that the
blob just gets sucked right up onto the
iron i got it and the excess goes there
you'll actually do better at this than i
do i don't do this much anymore because
of the shaky hands
wow there's a much better view than i
had a second ago all right
yes file
okay
any guidance here i love it that's good
okay now clean your iron okay
all right that was a good filing now you
have three joints okay
cool next up i would
see this one over here this little
resistor yeah on each side i would do
the same thing
so yeah just don't push it too hard
because it's very tiny i pointed out
with the solder here so i make sure i
got the right one that one
yep there yes sir okay and i'm going for
both sides of the top and bottom
basically
yeah
wow i i think my worst skill here is
the scope there we go
the hardest thing is proprioception it's
like knowing where you are without
seeing like i'm bad at this at the gym
my trainer used to go on about this it's
the the ability to tell where a part of
your body is without seeing it
and i'd wind up losing my balance in the
middle of exercises and falling over
yeah is that something i need to worry
about or no
just wait no no just go smell it okay
and
just a little bit more filing more
filing yeah like a file in a nail and on
the other side as well the reason i'm
doing that is because on the other side
of you see that green [ __ ] yeah anywhere
that that green [ __ ] went like corrosion
stuff
should i turn the board for this one or
would you just go in through i would
just go on the top like that okay
solder the
bonus points if you don't touch the
capacitor above that resistor so you're
going to have to angle your iron so
instead of being like this it's more
like this
i see the
oh that's not an inductor that is a cap
okay gotcha you mean the large one right
yeah okay
i was thinking that's uh
inductor but it is a cap
more yeah okay make contact
there you go yeah
that wasn't great
so how do we get rid of the it's not
soldered on there just poke it with your
with your tweezer with tweezer okay yeah
there's no way that there was enough
there was no heat there so that that
ball is not stuck to that cap
don't you have to pick it up just poke
it just poke it yeah uh
it feels feels kind of odd
yeah go for it
oh okay all right it was it was
superficial yes
i'm a little worried about stabbing too
hard on something that you're going to
have to clean up later what brings steve
to new york is vikkason he said he was
considering moving here he considered it
way more relaxing and affordable than
north carolina that's right yeah he said
he was uh we were actually gonna switch
yeah
that's right we're uh
you're gonna you're gonna move to my
headquarters and i'll move into this one
and
everything will be great
i i don't know how you can handle new
york i felt like i was gonna have a
breakdown just walking around outside
with a because like certain parts of the
city it's so loud yeah i have my i have
my uh my iems in for most of the time so
i can't hear any of it i got them in
2004 and i always have a mom when i'm
outside and if i forget them at home for
one day
and i actually realize how loud
everything is it [ __ ] with my head yeah
all right so uh so shouts out to
catherine anna hauserman for buying mr
clinton a set of greenies i'm going to
do a video of that later tonight thank
you so much
so do i need to do more work on the top
side of that i think i think that's
better now i want to see if it turns on
okay let's see if we have a fence all
right
you have a fan spin on your first try
because i yeah we're gonna have a
backlight issue in a while maybe a wi-fi
issue but
back like that stuff's optional
you know what
so we're looking for fan spin
yeah
this comment is actually uh oh wait the
actually helpful to me
is it spinning oh wow
so i want to come back to this in a
second but they come out from a
stational list saying just pretend it's
a poorly manufactured riser cable poked
all you want that actually is helpful to
me because that tells me how much
pressure i can apply
uh do you know the story of the riser
cables i don't know anything about riser
cable tell me there's a there was a
riser cable that was in
a mini itx case for pcie
riser cable and they had a
12 volt power plant at the top
that was getting clipped when they would
put the screw in
and uh it's getting clipped because the
screw was too large for the hole
and so it was actually screwing into the
pcb and not into the case
and uh
and also if you scratch the surface of
it then you get like a 12 volt plane so
you could short it to ground into the
case what company made this ship nzxt
uh they have since recalled it and think
well the government made them do a
recall but they got that far better now
yeah it got that far cpsc got involved
did they know that they were selling it
at the time that they were selling it
they knew they were uh who nzxt did they
know that that flaw existed did the
government tell them hey by the way this
is a product you may not know as an
issue no or did they know it was an
issue and they're not not getting it
they know it was an issue they started
shipping plastic screws as a fix which
is really only our concern with that was
like then you're gonna have long term
uh if the riser gets used later and they
put a metal screw in it because they
think it's better you know now it's the
issue's still there and um also buy from
that company and they were not even
shipping it was taking them months to
get the plastic screws out to people
jesus christ they have fixed it now but
you know only after when we applied
months of pressure and i would never buy
[ __ ] then they fixed it so
there's your story time for it you fixed
the maxwell so okay can you
and hopefully they can hear you okay um
the editor
can you explain to me what exactly
uh got fixed here sure
so the it had no green light in the
charger and in order for it to be able
to communicate with the charger there's
a chip called the smc okay over here
uh system management controller
has to work let's find it on the screen
this software was made in australia by a
man named paul daniels
what's it called
flex board view flex board view okay
okay yeah so this chip needs to work
this chip is powered by a rail called
pp3v42 okay and that rail was missing so
what i usually do when i look at the
board is i'll take a look over here and
try to figure out which rail uh where
the corrosion is and what what's what is
that is that for so this area was
corroded
and when you scroll down over here it
says backlight
backlight you know fine but it's
backlight is not necessary for it to
turn on then there's this
where this thing's plugged in and this
is airport wi-fi wi-fi that's even less
important they can use ethernet oh you
go over here
and this thing was corroded
and
this is a 3.42 volt power supply your
corrosion was on these three things here
so pins two three and four
and that so two
three and four so
this over here
all of this was shorted together is this
the chip name right here yeah okay so
what this thing does is
let's get schematic only
it takes the 18 volts from the charger
and turns it into 3.42 volts uh for the
system okay got it
i see
and so at this point
now this if you were
uh
working on this for i guess for a full
repair for a customer at this point do
you basically
just make sure it's all working and
you're done or do you go through and
clean up the other spots you would i
really like your computer down here on
the floor by the way yeah i like the
fact that the radiator does is outside
the computer because i'm an idiot that
doesn't know how to no it's great put it
together that's yeah lewis has a
got what looks like maybe a not a 680x
oh it's a corsair air carbide or
something i think that it's a very
overrated case
and uh he's got the um
fans mounted outside of the case
with uh the front of the case has been
replaced with
a dust filter there's no more front of
the case
the side panel's off there's a water
water cooling hose handing out of it
steve was gracious enough to ask would
you want us to make you a computer
that's the politest way i've ever heard
somebody say this computer looks like
[ __ ]
i i yes sir uh
twitch chat right there there you go can
we hook lewis up with the new pc i
offered that's what he was just saying
for his mic
i'm a cheapskate i'm going to be using
this i appreciate the offer i'm going to
be using this computer until 2035.
because the computer i had before this
one that i put together a few years ago
i was using for
about 10 years or so
so you think this will last you for
another decade
probably
so now
what are you working on now just clean
up the other spots yeah any area that
had even the tiniest bit of corrosion i
am i am actually trying to learn here
and i
i've learned a few valuable things so
far like you can't have enough blocks
it's one of them yeah so here's the
thing paul will use this amount of flux
like this right right this is paul
that's okay this is proper okay got it
okay
never use a paul amount of flux it'll
backfire on a okay
do you you know those motivational
posters they do in offices have you ever
thought of getting that made and just
putting it up
you need like a door cam so you can get
people popping in
it just the whole idea is to put back
together every joint that is either
shorted to something else or that is no
longer connected and 99 of the time
this really is just a janitor's job okay
you're just being a janitor
now sometimes there are capacitors that
look like again i don't know if that
burn mark is from the liquid or if that
burn mark
is from uh
yeah something else getting stabbed or
something yeah so
what are we looking at i see an inductor
are those two two caps this capacitor
scares me okay it looks like it could be
short at the ground
but it's not where are you seeing
where were you saying you thought was
the short uh see this yeah
that was just dust
i thought that was an exploded cap but
yeah
three three thousand ohms yeah that's
fine that's that's a thousand i [ __ ]
up my scenes in obs that's why you can't
see okay the thing
that's there and then you just go
through every section of the board where
you see like
see over here there's uh
what what would be a warning sign to you
on that the one you just looked at
like just zero or yeah if it was zero or
like it was zero point zero zero zero
but that also had a k in it that you
couldn't see on the screen because i
suck at using obs but that was three
thousand ohms
and then you see over here where the
solder is starting to come off yeah so
you want to go through the this is going
to come off in the ultrasonic cleaner
but my idea is if the solder is coming
off that means that these components are
barely hanging on there
so
so i want to go through each one of
those components and kind of juice up
the joints a little bit right so what um
i know you've done this in a video i
actually watched on your videos i was
years old
about flux
what uh
can you explain to me like the core
function of flux what
it allows solder to flow so i'll show
you what this is what happens without
flux let's see if i have an example
there does it just stick without flux
basically oh [ __ ]
so i'm going to burn out all of the flux
over here okay
just turn the hdr back on and for twitch
he's demoing flux versus no flux
all right
see see how it looks like a hershey's
kiss
you have a spiky jaw yeah
it doesn't flow okay
it looks like that
is flux something that you need to uh
thoroughly clean up is it conductive at
all this flux is not conducting it's not
conductive you could leave it there it's
not
now this is with flux
creates a nicer little
right way way better
okay
they're saying your sound is fine right
now that's good okay cool yeah for those
who showed up late i only have one
wireless transmitter at the store so i'm
recording my audio track to my zoom and
i'm gonna put it on the main channel
version sorry
why does this guy sound like steve from
gm do i sound like do i sound like that
guy
you sound very similar i sound like
steve from gm that's weird
oh or something like this
you want to go through what is that it
looks like it's a scene from alien or
something like
nasty corroded [ __ ] uh
is that really just corrosion yeah
it
and this is how you learn it's yeah
there are all these areas that are
corroded and the way you learn what each
area does is like the computer comes in
with x problem and it's corroded in y
spot so then you you realize that
corrosion matters in this spot means you
don't have wi-fi but corrosion in the
spot means that it'll be taking 20 mil
amps instead of 500 pounds okay
is most of this all water damage
basically yeah liquid damage i guess
more
[Music]
appropriately when do you feel like you
got good at this like
how how
far sort of into
playing around with it you know do you
feel like you actually got pretty good i
started trying to do this in 2009 and i
didn't feel comp semi-competent until
2014. okay so five years what i had the
slowest learning curve i mean it took me
a long time to figure out what i'm doing
too it's weird because there are people
on my in my comments that'll say you
know i wish i was that good like i'm 18
months in and i'm like 90 of the way
there it's like it took me five good
yeah but it's like it took me five years
to even remotely i i was probably the
slowest learner of including most of the
people that actually listen and watch
this channel right right yeah
i just didn't record it because well
that nobody would send anything what um
which skills do you think
were like is there a certain skill you
can remember was particularly difficult
for you to learn
reballing a chip
okay wear one of these
and the rest of the junk is going to
come off in the ultrasonic cleaner all
that little little rubbish so like this
up here is that something you're going
to clean yeah like the the ultrasonic
clean is going to get rid of all that
got it the the part that's hard is let's
say a chip like this has 96 balls under
it and you have to take
uh i would have to take this chip off
and then
take manual for yeah and then to reball
it
there's a jig but you have to find the
jig for each chip and if you don't have
a jig for that chip then you have to
tape the chip to the desk and then find
a stencil or if you don't have a stencil
then you have to manually put each of
the individual balls there which i have
seen people do before
but that's no fun so
for um
for
revolving is it basically it's like a
stencil then i guess and then
um
do you use a special machine to flow at
all when you're done
or do you just heat it with a hot air
gun or whatever you just heat it with
this oh that's it okay yeah there's a
paste that you put on there
so here you got a paste the paste goes
in the top
you wipe it off the paste fills up all
the little holes in the stencil okay you
use that is it a solder paste is that
what it is yeah in an ideal world that
would work half the time the balls try
to jump out of the holes that you and
then combine into the other hole and
become a bigger ball
right
that's that's all part of the fun
i've seen this
in large quantities at um motherboard
factories where i don't know if you ever
see like a motherboard get made
uh like i've never seen a board get made
okay you should uh
uh we've got videos on it but if you
ever get over to taiwan there's a good
factory but anyway
they have um
i guess i don't know if solder mask is
the right word i think that's the right
word but they have a mask
that they apply to the blank pcb
uh
and then there's this big brush like um
i was like just like a toothbrush except
ginormous and all it does is apply like
solder paste across the whole board just
the mask they pull the mask off and then
they send it through the oven and that's
it like it's taking all the soda that
sounds very sexy it's i gotta watch it
it's super cool that's why i was asking
if there's like a machine you can use
but uh there probably is it's just the
cost of the machine
and the space cost for you right in new
york like
well you also have to have the balls be
the right size so they're soldering it
after they're soldering something on
after it's already balled i imagine yeah
because when they manufacture the chips
they come with the solder balls on them
right right right
kick that off please the uh down here i
have to get a remote for it paul is a
remote in his desk thank you very much
so you fixed the board
it didn't have fan spin you put your
soldering iron to the board it had fans
hey good job
lewis good job you nah i i do genuinely
appreciate the coaching though like
because
um
so i've a few key areas i know i'm
pretty weak in
knowledge-wise and i don't do much
soldering
uh whenever i do though every time like
i really need to find time to sit down
and just work on basic skills so like
for me it's been my biggest problem has
been um
i think some stuff that would be
extremely basic for you like like um
determining is this the right type of
head on the soldering iron right like
uh or when you're making contact or not
because like you could sometimes people
will grab will touch the chip like this
instead of like this ah right like
what i see a lot of people do is like
they'll have a giant a joint that looks
like this and they'll have an iron that
looks like like this and they'll do this
instead of this got it right it's like
800 this little 800 degrees is the same
technically 800 degrees as this but it's
a lot less effective okay yeah
and then uh
i i feel a little bit better using the
microscope after being here um
but one of the things i do at home and i
should probably switch to the actual
like
optics because i try to use a monitor
and i feel like i'm
nothing makes sense
because you got the monitor off at a 45
degree angle from where you're working
i've tried looking into a monitor with a
digital microscope because everybody you
know that you can get them cheaper i've
never been able to i feel nauseous like
it makes me sick trying to actually look
at it while i'm doing it i can't figure
out how to do that
yeah so what um
i guess for working on boards like this
is this kind of the most common type of
issue you see at this point like like
corrosion and
liquid damage yeah it's an easy repair
or
well depending on the model of the board
some of them it's just you know an easy
peasy
three volt circuit that doesn't work on
some boards the liquid always goes where
uh on a something that turns 12 volts
into one volt for the cpu those suck
because it's the exact same thing it's
just you know that the cpu got 12 volts
every single time and they don't they
don't like that
the core 2 duo you could send 12 volts
to and it it's okay but it's that that
was a really really really long time
yeah that doesn't that doesn't happen no
like modern little like kb lake or sky
like you're like one point something now
like one one point
1.5 is getting kind of dangerous yeah
like with liquid nitrogen the max will
go up to is
you get into like one eight 1.8 1.9
territory
even a quart to do i think was 1.65 1.3
volts but they could survive a quick 12
volt hit before it turned off this a
quick 12 volts it's just it's completely
dead and destroyed yeah that makes sense
which so on a lot of the new it really
whether or not it's easy to fix or hard
to fix depends on where the water tends
to land in that model and what is
usually there
they're saying new intern
can i have a job absolutely okay all
right and now i can i'll get a mop and
start cleaning the floor i have a place
that works here i can we should switch
let's do a week of switching yeah
no you do board repair here i pretend i
build computers that look like this
there well i'll edit in a picture of
this [ __ ]
for the video
that goes in the main channel
uh i want to do a build for uh we'll see
what we can work out i think you would
take some motherboards do paul's build
or do a new one for you here i think you
would fix motherboards way better than i
would build computers
i give it a week or two i don't know
about that i don't have i don't think i
have the patience to do what you do i
don't have the patience to even put my
case back together yeah well but that's
different type of patience this doesn't
it doesn't need the case doesn't need to
be it also works like high high it was
making a weird noise the other day and
then i noticed the water loop had
bubbles all over it and it's like i
don't know what the [ __ ] i'm doing it
could be
the loop had bubbles like like air
bubbles are like water
oh it's like air bubbles and then the
reservoir was almost all the way down to
repair here and it's gonna come out of
there yeah
yeah yeah it could be um a fitting
because the each of the fittings has an
o-ring at rubber o-ring and that's the
most common point of failure on an open
loop is uh
the o-ring will dry and crack i thought
i was too stupid to put together my own
loop so i bought that enter max tr4 and
then it started making weird noises and
then i looked at your review of it and i
face palmed immediately forever buying
that piece of [ __ ] almost i think they
recalled
all of them i doubt they got them all
back but it was like basically a 100
defect rate
so
did they great did they refund people
for those
they said they were going to i helped
several people get refunds because they
were being denied
and then they would email us and then i
would email enter max and say
i never got my money back for that i
figured i could just buy like if they're
not going to refund me i could just do
the old school buy another one and
return the old one in the box thing but
then i just have another piece of [ __ ]
so by not by not ever releasing a
version that doesn't suck they [ __ ] up
my ability to even scam them to get my
money back yeah yeah they they tried
several times but i think most people
just gave up and got a different cooler
well steve clinton later on cat
collaboration my cat is not here
unfortunately mr clinton
i've seen a lot of mr clinton in the
videos i anna sent me all those greenies
thank you anne oh really i have to give
them to my kitty green is from uh
viewer
yeah
she's a mod and okay my cat's gonna
scream when he gets those yeah he's a
crackhead
does he chase him if you throw him or
does he uh look at you like you've done
him wrong no if i throw it like he'll
see where it's about to land and
immediately jump okay great yeah yes
still active then
yeah so the board
i feel
um i think the the biggest differences
here with your setup and mine other than
the professional level of tools and
everything but i don't have
a hot air gun so that's the difference
uh i've got a board heater that
it's it's just like um
you know just uh
i don't know like some heating elements
under a grid and then you suspend the
board
um
so i have that i don't have an air gun
though
and i felt like that made things a
little bit easier than what i'm used to
what do you ever use board heaters here
or
uh yeah they have a pre-heater over
there and when you're replacing a cpu or
a gpu on a board that the machine has a
pre-heater built into it i see for these
i just wind up preheating it just using
that like i just hold it from far away
and then i slowly go on
cool
then the other thing is uh the
tip you have on the soldering iron here
is much finer than what i'm working with
but i don't know i was working on
different stuff so yeah if you tried to
use that for something like a gpu shunt
resistor it would just get destroyed
just because it's not enough
it's so yeah it's pulls all the heat out
of it way too tiny yeah we i have a big
i have a 250 watt iron that i'd probably
use for that that's the one that i use
for for bike stuff i see yeah
yeah cause i mostly work with like the
shunt like the five million shot
resistors does it is the iron you have
work or does it take feel like it's
taking forever and the board is eating
up all the heat uh
it feels like it's the last time that it
felt like it was taking forever and like
i would have to like kind of wait till
it hit the max temperature and then try
how often do you do this
twice a year and every time i do it's
like maybe
eight shunt resistors do you plan to do
it again yeah yeah i have something for
you to take and try okay
[Music]
he's louis is getting something from off
off camera what video card is being
worked on so i wasn't working on a video
card i was working on a board he had
here from what was it from
macbook air
yeah it's a macbook air 2004 15.
and uh as for to answer the question
though
the video cards i was working on
in confidently i'm not good at this was
uh they were 30 90s and 3080s i did get
the mod done but
um
so the mod that we showed on the channel
was a piggyback shunt resistor mod where
you take like a five million resistor
put on top of another one and
nvidia's logic
uh uses those shunt resistors to try and
evaluate how much power is going to the
core
and it limits it to a certain wattage so
if you put another one on there
uh you can trick it to consume more
power than it will normally allow which
is only useful for overclocking and
nothing practical but that's why i was
doing it try this
oh wow
you don't need this
can i pay you for it i crimp now
okay
enjoy i got a free labor of you fixing a
board
yeah but you taught me to do it i do
crimping for all of my electric bike
stuff now okay my controller is sealed
so there's no repair so
um so the way this works is when you
plug it in
any settings or anything are you just
plugging in you got on and on okay
on and more on
so
this is it
okay
so this is a little on
and that's a lot on got it
and it it the is it just this one
head for it this is all you get okay
this one head this one tip and then uh
and it but
it doesn't matter how much the board
absorbs heat this is going to heat it up
because it's 260 watts you just have to
make sure that this is screwed in
properly because it can become loose and
once it becomes loose it doesn't conduct
properly okay but you do this and
so for and i guess the reason the um
the
smaller soldering tips for something
that's it so is the problem that it's
what i'm working on is a larger
component like a shunt resistor or is
the problem that
the board is soaking so much heat
uh it could be the well the shunt
resistor is going to be in an area where
all the power that goes to the card is
passing through it or all the power that
passes that particular chip is passing
through it so it's going to be the board
as heat is is take grabbing a lot of it
away from you the board is soaking all
of it away from you right so you could
either a heat preheat the board and then
use a smaller iron or b just you know
use a bigger
yeah i appreciate it also if you if i
plug this in and you try hitting the
trigger one thing that's really cool is
you can actually feel the transformer
vibrating in your hand
wait yeah try this
wow that is actually i know it vibrates
in your head so is this this is it
didn't sound right this is more on yeah
okay you have to
rossman real estate
what is he fixing
knob and okay i don't know what the
question is there
steve this is super heavy duty stuff for
gpu power that one will be plentiful
plenty powerful
it definitely uh is a lot more than what
i'm
what i've been trying to use also a few
i'll let you know how it goes because i
have one i want to do some work on soon
so if you want to deal with like four
gauge or eight gauge wire for your
electric bicycle yeah
yeah my uh
my completely street legal
electric bike
that was the most believable
it's
i i can ride it uh as long as nobody
sees it then
there's not a problem really
i'm surprised that in new york city i've
never been pulled over with an e-bike
that is clearly illegal
and and and you actually get regulated
harder in north carolina with an
electric bicycle that you bought you
didn't build any crazy [ __ ] yeah and
then use a controller that puts four
times the rated wattage into your motor
so that you can go 50 miles an hour
right you are using a store-bought ass
no store-bought e-bike built by somebody
else probably certified ul all that [ __ ]
and you get pulled over yeah i ride some
crazy-ass [ __ ] that i put together here
in the back of my store that's because
nobody gives a [ __ ] they see yours and
they're afraid it's gonna explode or
something
they don't want to stop you because
they're afraid of it
i don't want to be near that thing or
they know you as the guy with the other
e-bike that's it right there right yeah
fire one
that that was scary when you posted
about that that made me
sort of question
my uh
it's like when we were working with the
ndxc riser cable with the fire hazards
where every now and then you see
something bad enough and you're like wow
this makes me question all electronics
now yeah one of the things that i do
with any of the e-bike batteries that i
buy before i actually use them
is uh do you have a tester or something
one thing i like to do is
i actually open them and inspect them
now before i put them in my bike i want
to see what you create how do you wire
it right do you actually use the cells
you claim you use because the big thing
with e-bikes is they'll lie they'll tell
you we're using samsung 35e or 30q or
whatever and they'll put some other
[ __ ] in it so if you open the e-bike
batteries that you get you'll often
realize that the seller didn't sell you
what they claim they sold you
so i open up all the stuff before i
actually put it in my bike that's what
happened to you on this one right it was
not this one that was the other oh that
has a frame the one that i that other
one like the frame is literally just
poof yeah okay they they claimed they
were giving me samsung 35e cells i paid
extra for it you open it it's just
[ __ ] no name no brand no nothing
right so i i like em 3v i'm a big show
for them because the the the
internal construction no sponsor or
anything it's [ __ ] beautiful like you
pay more money but there's craftsmanship
that goes into how they put that
together
and it's it's absolutely beautiful like
the way the the there's temperature
sensors it'll automatically turn off if
it's too hot too cold they very very
conservatively rate their power ratings
like that one that can easily do rms of
3000 and they rate it at rms of 1500.
there's a
you you might like this there's an
attachment i wired into mine that it's
just a small computer with a micro sd
card reader on it and um it'll do gps
tracking of the bike and it'll do uh
which is useful for multiple things with
theft being one of them but um it'll do
gps tracking and then it also does a
logging of temperature of the internal
components and speed
so you can create like a gps map of your
route if you want you can check the
temperature like whatever component it's
monitoring over time but
i it was cool because um i used it for
hub motor temperature and tried
attaching different heat sinks to the
hub motor externally
and there are all these heat sinks that
are marketed for this online and none of
them did anything like they because it's
too far removed from the source of the
heat at that point
it's on the outside of the motor right
so
um
but uh yeah they're pretty cool you just
wire right into the i actually have that
same
uh readout on mine
wired in and
you get a computer on your bike
another computer on your bike i like the
thing that it tells the one that i have
it's a cycle analyst it'll tell me how
many watt hours a mile i'm using and all
that stuff
so i can i can try to learn how to ride
more efficiently like i always try to
see can i get myself down to 20 watt
hours a mile from my trip home
do you actually try to ride more
efficiently on it yeah just go full
throttle i guess you probably can't even
go full throttle with the traffic here
anyway but if you go on the side of it
but that's another story all together
thank you very much no thank you i
really appreciate it no i i appreciate
the education i learned a lot i feel
like i can
make use of some of that and look
forward to your next gpu shunt video yes
you will see that 260 watt done you'll
see that in the next one
thank you see you sorry for the [ __ ]
audio on the main channel i'm going to
upload this i'm a schmuck i forgot to
bring my wireless transmitter with me so
i'm actually recording this to my inter
this thingy and then i have to put it
into the main audio later anyway
see y'all see you next one
