i can't wait to show you guys this it's finally here my diamond play button
you're probably thinking to yourself gee Linus you have like 13 million
subscribers how did it take you so long to make a video about your time and play
button that is because this is a diamond play button like no other diamond play
button guys this is mother Linus tech tips
this diamond play button is gonna have a pc in it

step one of building your very own diamond play button pc is of course
getting a diamond play button the process is super simple all you have to
do is get you 9 million hundred ninety nine thousand nine hundred and ninety
nine of your friends to all subscribe to the same youtube channel then you
request your reward from youtube directly and they send it in the mail by
the way guys thanks for your help with that step two finding a pc that will fit
in a diamond play button the x y dimensions actually not that hard to
deal with but the z height is not that
thick by the time you factor in cooling so we went with this Intel nook it's got
support for an m.2 SSD up to two slots
of sodium memory and this right here is a core i7 10 710u now going with 10th
gen we do give up Intel's tiger lake xc graphics but what we gain in return is
six cores and with this particular model the ability to go real fast if we can
provide adequate cooling and the reality of it is guys is if we really wanted
fast gaming performance out of this thing we would use an external GPU with
Thunderbolt anyway so this feels like a great choice massive shout out by the
way to simply nook for sending this thing over to us they do sell this and
many different models of nooks usually they look more like computers than this
so you'll have to check that out man the job they did on this thing is oh yeah
it's beautiful like are these beveled edges oh yeah there's no sharp edges on
there this is unreal craftsmanship but we'll get more into that later for now i
want to show you guys how the pc goes in here so you see these four standoffs
right here it's just going to go a little something like that and the
reason that we want to lift the pc up off the bottom of the play button is
because that's going to give us room to kind of jam our cables down there and
also give us enough clearance to run our cooling over to this heatsink i o access
is right there see that
this is cool pretty much everything i'm showing you guys today by the way i am
seeing for the first time because alex did this project almost entirely
unsupervised so this appears to be my CPU cold plate yep and then these
are presumably wow that's a snug boy fit
isn't it i mean that's good for you know thermal transfer and all that but these
are heat pipes oh okay so i'm gonna
screw this onto the CPU then right well first you need to put all the heat pipes
in and you asked for us to solder them i
don't know if you still want to do that but we can how much work is it to solder
them the thing about solder is that it needs to melt onto the surfaces that
you're trying to bond and the thing about heat pipes is that it's designed
to move heat away really fast so heating
up a heat pipe enough at the point where you want to melt the solder without
heating up the entire thing so much that it explodes
is a bit of a tricky matter we've never really successfully done it before yeah
we should be able to with that okay smooth flow solder paste slow temp may
be possible let's do it before we actually put that in place though
there's three more smaller heat pipes that we're going to use just to
spread the heat out within our heat sink here so the idea here is that we've got
heat pipes carrying the heat from the CPU transferring it to these heat pipes
which spread it out in this heat sink now we probably could have gone fully
passive but we're gonna add a fan too so this thing is going to perform like
pretty amazing we hope it's never actually been fully assembled i've never
soldered a heat pipe before basically just rough it up with a little bit of
scotch brite is this kind of like a less is more situation or do you even know
i'm not totally sure but you know that it flows at 138 degrees though and this
is what people use for soldering heat pipes i'm sure that i'm doing this
completely wrong uh it's what i was told
by the internet yes here we go so
i mean hey the good news is it's kind of like looby compared to before well no it
goes in a little easier alex am i even sort of doing this the way you're
supposed to because that would be really good to know like in the video where
they told you to use this stuff did they at all show you how to put it on they
kind of just put it on and put the heat pipes in well i definitely am doing that
it didn't look like this okay i think
i think they're in so theoretically this will melt and it will solder this to
this oh wow look at it go holy i think it's working oh yeah damn i wish i'd
applied it a little more cleanly but we won't really see this it shows on the
flare that it's above 130 degrees celsius i guess that's as high as this
goes i mean that looks pretty darn
soldered to me if you want we can also try soldering in the other heat pipes
since that seemed to work well but i think that'll take way longer yeah i
think it might be okay though okay i think this is the coolest build we've
done in a long time it's the Linus ego build i think that was the gold
controller i'm gonna be like celery sticks you know kind of spreads like
peanut butter too actually we're doing two things right now we're heating this
up to melt our solder flux paste and
then we're also heating it up so that we can push out the plastic or whatever
it's made of diamond oh wait we like basically can't thermal image of this oh
because it's too shiny yeah it's way too shiny you know what would be great is if
we put a piece of tape on it or something because we really do kind of need to know how hot it is i think a
little bit that i could see melted uh what's the temperature of the tape
tape's 106 degrees so yeah you must be good let's also pop out the button like
very soon don't touch this hey yep it's a little toasty okay
oh it's out it is way deeper than i thought it was yeah that's one of the
reasons that it was so hard to find a pc to fit in while i wait for this to cool
down i can go ahead and remove this electrical tape oh
it's leaving a nasty residue unfortunately we had no choice because
in order for our thermal camera to be able to read the temperature of this
reflective surface we had to put something non-reflective on it which
actually leads into a really cool story how on earth did we see and see out a
diamond play button without a cad model well you can't so we had to get one now
the most obvious way to get one would be to ask youtube for it i mean they
designed it so they should probably have it and they do but unfortunately
youtube's lawyers would not allow our contact to send it to us for the
purposes of modifying it to put a pc in so we had to 3d scan it which
guys is no mean feat because the way 3d scanners work is they bounce light off
of the object and then record it in order to you know get all of its shapes
and curves and oh no this thing is a freaking mirror how do you 3d scan a
curved mirror you give it to a professional so we enlisted the help of
le mans designs in north vancouver and omid over there i don't know how he did
it but it freaking worked and um great
job guys this is the raw scan file how
i don't even they should be cooled down now so we can test if these are in oh oh it's still
hot but it okay ah balls does it do aluminum because it
seems like it just didn't really adhere to the aluminum after further research
it appears that our nc 191 lt50 solder
paste is not ideal for aluminum and
copper so we roughed up the aluminum again
put a little bit more of it on this time and we're gonna see if we got a good
joint otherwise we're gonna have to go to thermal paste or thermal epoxy
actually i think it fell i think it uh wow bonded oh heck yeah
well that cools there's two things that we can do we need to put i o in here
this needs the chop yeah we're gonna just steal this epoxy it in here oh we
need to solder the front panel connectors onto
here where the hell is the power button you know well we kind of get to just put it wherever i want because the hole
isn't drilled yet but you can go like here or here or here what do you want
for colors i'm thinking i'll just do like a rainbow sure actually hey Linus
yo i just realized something the uh wi-fi antennas are just hanging out in
here should we take those out and put them in like a spot they might work uh
yeah i would like to have wi-fi for the i o we didn't want to cut it into the
actual play button because for one it's just difficult to cut in here and also
like if you get it a little bit wrong you're kind of just screwed so instead
uh story simply knock but the thing that you're sent to us is about to die
and pencils down are you done yeah i'm just waiting for you at this point well
i did a really good job i don't even need shrink wrap i think you should still put it on there okay just can you
please appreciate that i did a good job and i probably don't need it i did a good job Linus i'm proud of you actually
i just realized something we should probably add some like connectors or
something to this because otherwise we're going to have to install this
power button and that board at the same time it's going to suck oh i have an
idea Linus we just take some of these male and female little pluggy chummies
solder them onto there and solder them onto this so then when we want to put it
together we just so really i soldered the wrong wires
here though so i'm doing completely unnecessary soldering a wire to another
wire well but now you can solder another wire to that wire and it'll be not that
hard yeah just what i could have just cut off of those wires and then the
connector would have already been on them yeah details okay so we now have to
properly decide where this power button is going to go oh this is real final
isn't it yeah oh that diamond cutout that looks so cool oh yeah it looks so
sick especially with the fan underneath it where exactly do we want this so i
don't know like here here you went up here i thought we said
it was going to go down here how about like here here yeah sure uh
see why do you ask me to pick and then tell me it's not a freaking option put
it wherever the hell you want i don't care anymore that sounds good
i like this
that's a nice hole check this out we're freaking good to go boys oh god wow
that's really tight that is actually a really cool tool that
i have never seen before and i love it but you've never seen a deburring tool
before okay that worked perfectly is this it do we assemble leds this is what
we're using wait what let's light up your wonderful life and then we're using
this what and the fan's also being powered by this wait what
why because the nok only does 5 volt for
fans and there wasn't a five volt fan that would fit in here correctly put it
there tape it or hot glue it take the next one oh my god that's horrendous
well we could also have done a completely custom solution this is faster yes there's only one way to know
for sure if these strips will
bond to cyanoacrylate that's to use my finger and try and stick it to it maybe
you should double check with your hair too so what about we use this moment oh
god that's a lot of ca i don't think ca sticks to aluminum fortunately we have
this bond aid epoxy putty stick alex
wouldn't let me handle this with no gloves it's not good for your skin so i
just mush this up then yeah it should be a bit hot while i'm working on that is as good a time as any to talk about the
actual design of the pc itself so what i'm holding in my hand as you can see is
not made of metal this is a 3d printed
mock-up so that we could do a test fit and also just kind of a general sanity
check it's all fine and good for alex to create it in solidworks based on that 3d
scan that we got but it's another one entirely to double check make sure the
scan was actually freaking accurate and make sure that our components are going
to fit so because our printer bed isn't big enough we printed it in two pieces
and it was great so from there alex was able to send our
file along with our diamond play button to a bloke named amish this kind of
machining is very out of our depth at least for now but holy frank did amish
do a great job of it using his dmg mori
dmu-65 monoblock a 5-axis cnc machine
with a whopping 46 horsepower spindle it
could have made very quick work of this but believe it or not amish went out of
his way to make the tool paths complicated so that the cutting would
look extra sick on camera for all of y'all
one unfortunate thing we learned while cutting though is that although the play
button is made of aluminum and youtube actually told me that it is solid
polished aluminum and nothing else it has actually been electroplated in
copper and then chrome so what that meant was that no matter how much we
polished the aluminum back panel we made it could never have the same super shiny
surface finish as the rest of the play button i do think that the cut out
diamond looks absolutely so good
crap even this epoxy came off nothing sticks to these stupid things look it's
not that we wanted to use double-sided tape so i wanted to use double-sided
tape and tuck tape we didn't ask for this
how freaking awesome does that look we don't
actually need this much of this adhesive to keep the diamond in place but what
we're doing is trying to ensure that we have a consistent look to this shiny
piece that goes under it so we're covering the entire thing
i see what you mean about it being hard to get it like centered
oh jeez Linus you know what we're rolling with it alex so this is gonna go
here we could like spend an hour cable managing this but i really don't think
it serves much purpose are you sure this usb port has enough power for everything
that plugs into it uh pretty sure i guess that's only six leds and a fan
that should be fine yeah okay honestly i think we can just pressure
fit that i'm down yeah like that's awesome that's not going anywhere in a
perfect world i wouldn't use thermal pads for where we're crossing our heat
pipes here but the truth is we don't know how well this is gonna work so at
least this allows us to run the machine and
validate the concept this thing's sick 32 gigs RAM well it's not perfect by any
stretch i mean for extra credit we could have soldered to these little tiny usb
headers and put like an RGB controller in it and stuff like that but honestly i
am super happy with what i think is about to be the result are we ready to close
it up i think so yeah fans in
computers in the i o looks amazing oh my god that looks
so sick man been planning this build since before we even had 10 million
subscribers this is freaking incredible check out that i o david is that clean
or what alex you did a great job of that that is custom built
let's get hardware info up here gets in a bench up oh my god this is so
freaking cool my computer is a play button and my play button is a computer
okay we ready minimum test duration
test for thermal throttling CPU multicore here we go are you rolling on
this right now because our load temps
are like 60 65 degrees mind you you know we're
maxing out at like 2.85 gigahertz because this is a u-class processor but
still come on it's a play button how quiet is it though
it's whisper quiet oh my god this thing
is so far beyond cool alex you
did an amazing job on this this is
nothing futs get it get it i don't even care that the jewel has a crack in it
that just adds character at this point what i want to know is how much it'll
turbo okay CPU single core man you could
game on this puppy fine just fine we are
getting four flippin gigahertz on it hold on a second
no no no no hold on hold on don't turn that off yet we were hitting like four
point three four point four four we we touched 4.5 for a second there i think
there were some background like app updates that were hitting multiple cores
man when this thing's gaming like external GPU or something it's gonna be
a freaking beast i love it and you know what else i love i was gonna segue to
our sponsor but first you guys i know it
took a while for us to get this project done but thank you very much 10 million
subscribers is an absolutely unbelievable accomplishment that we
achieved a long time ago and we really appreciate everything that you guys do
to make this possible and we also appreciate our sponsor the drop enter
keyboard is a new keyboard from drop.com made of course with high grade
enthusiast class materials it's got an aluminum top plate with white leds so
you can read the keys in dark conditions it's got double shot pbt keycaps and
weighs in at 964 grams so it's heavy enough to stay in place on your desk but
not so heavy that it's impossible to take with you on the go which you just
might do thanks to its 10 keyless layout it's available in three colors with your
choice of mechanical switches so don't wait buy it today at the link in the
video description i feel like normally when people do their 10 million
subscriber videos there's a lot of like soul searching and you know heartfelt
talking at their audience but the truth is i think i already did enough of that for
like four plus their apology videos so you guys
can go watch that to see how i feel about
all of that today it's just about being
cool like that's a computer oh it's warm it's
warm it's a warm boy
