I am going to blow up this power supply
with the tester behind me in fact if all
goes according to plan I'm going to be blowing up a lot of power supplies
that's right it's time for another lab update and this time we have got the
goods I'm talking finished metal 3D prints Machine Vision automated game
benchmarking and a special room to host
my own legally dubious 5G Network why
would I spend all this money in Risk prison time you ask for science now the
clever among you probably noticed that this was the first big piece of
equipment we purchased and it's taken us a pretty long time to get it running
what's the deal with that well there's a couple reasons first we needed an
adequate power hookup then we needed an appropriate
oscilloscope actually we'd still need an oscilloscope we'll get to that in a
moment finally we needed someone as knowledgeable about Electronics as he is
tall that's where this guy comes in because I mean who knows what would
happen if I came over here and twisted this style or pushed this button or
wait what does this one do
Segway sponsor the ridge upgrade your everyday
carry with the ridge wallet it's RFID blocking technology protects your cards
from digital theft while its durable materials ensure it lasts for years to
come even once the apocalypse starts click the link below and use code Linus
to save 10 off your purchase and get free shipping and we're back what you're
looking at is every harness coming off of the power supply connected through
these wagos to our power supply tester now the reason that we can't just twist
them together for our testing is that we also need the sense wires that are also
running back to our power supply tester so that we can see what voltages those
rails are actually running at because spoiler alert
3.35 12 yeah in your dreams Premiere
more like 12.34 actually the five volts really
close 3.3 is a little low these are all
well within spec though but we aren't drawing any power from it yet let's see
what happens when we change that sitch
I guess we are drawing a little bit like I don't know 40 Watts or 50 Watts or
something like that give me 150 watts
wait 150 on the 5 volt rail are you mad
wait oh this is a really old power supply 22 amps on the 5 volt rail
whew should I be touching this
it's shut off like that was it it's gone already I thought I only asked for 150
watts well hey that means the overcurrent protection worked though we
tried to draw a 150 watts on a rail that's only rated for
110 and it was like no okay so you got
50 Watts on the 12 volt rail okay how about 100 Watts
oh my God it's off again okay we're at 65 Watts
can't believe you've done this you know this was a very sentimental
power supply for me I've had it since before you were born
you can tell by looking at it I've seen comments questioning if we need such a
fancy tester and the truth is guys if
all we want is to test basic over current protection circuits or to see if
it just immediately fails when we try to draw power from it the answer is no but
we don't want to stop at complete garbage and well seems safe
enough good luck we want to put real pressure on manufacturers and in order
to do that we needed to close the gap between the professional gear that's
used to design these products and the hobbyist level equipment that many Tech
media Outlets have been stuck with so in order to do that we got some help from
reputable manufacturers see Sonic helped us spec this unit to begin with and
Johnny from Corsair AKA The One and Only Johnny Guru gave us some tips on how to
best use it we've also recently just completed our on-site training from
chroma and every component in this stack plays an important role starting at the
bottom where you'll find our AC power supply that's this guy right here this
can not only Supply an ample amount of power but it can also simulate a variety
of distortions which will allow us to test a power supplies behavior during
non-ideal conditions such as during a brown note this feeds into our big
switch as we call it which I've just been informed is completely redundant
the AC Source can also turn the power on
and off so why we need an on off controller I don't know and that
okay then we have our DC Supply which is
used to supply additional DC power to our over voltage protection slash short
circuit testing device above the desk thing we've got the jack-in panel this
allows us to plug AC power into our power supply and then also plug our
power supply into all the diagnostic equipment here including our timing and
noise analyzer as well as our programmable loads these can be adjusted
to simulate any kind of device you want though obviously we are most interested
in creating loads that will behave like a PC
why do we need so many of them you might ask well each of these can pull about
400 watts so say we wanted to test a
1500 watt power supply a 2000 watt power supply we would need a lot more than one
of them it's also really helpful for testing multi-rail designs now a really
cool aspect of programmable loads is that they can simulate the behavior of
real components like the big transient spikes that made the 3090 ti so famous
finally at the top we've got our multimeter and power meter which give us
all sorts of information about our circuit and would plug into our oscilloscope if I had one
seriously it's in the mail already and the first video we're planning is a
budget power supply Roundup does anyone actually make a sub 40 power supply you
can trust speaking of trust the Telecommunications industry am I right
we're gonna get it there behind me is our new EMC chamber Electronics go in
no electromagnetic radiation gets in or out that means we can put whatever we
want in here and cut it off completely from the outside world we can test Wi-Fi
we can test 5G we can test Bluetooth within this chamber we could simulate a
noisy environment or we could simulate a distant access point which can tell us
not just how fast and reliable connection can be or what bands the
device supports but even how battery life might be affected by having to
crank the transmit power due to crummy reception now you might be thinking whoa
slow down there turbo how are you going to test 5G in an impenetrable box
well with my own cell phone network of course
if I had one thanks to the crtc and
similar regulatory bodies you have to get permission to use the parts of the
electromagnetic spectrum that are reserved for cell phone service and that
permission is expensive Canadian Telco
spent a collective 3.5 billion for
licenses to the 600 megahertz band that's just one bed I can't do that so
instead we're going to be purchasing a fire cell lab kit we're going to go into
way more detail in a future video but here's the quick and dirty version if
you're a big company big like apple or BMW you would likely get corporate and
Regulatory approval to run your tests using an actual cell like the antenna on
a cell tower these are very expensive though full of corporate secrets and
frankly overkill for our purposes anyway the fire cell on the other hand is one
of if not the only off-the-shelf testing units and it allows us to test 4G 5G and
after an incoming update even millimeter wave and because the government can't
detect our Network as long as it stays in this box I am very unlikely to get
arrested for broadcasting on reserved frequencies in fact no one can even hear
you scream watch this
I couldn't help noticing the fire cell stuff is not here that's right so it's
arriving on June 6th uh it's you know
early birthday present for my wife
and dog house no it arrives on June 6th
okay uh we're going to have it positioned here on a desk we're actually
gonna have to get some floor cutouts done so we can spread some of the weight we don't want the table punching through
the the styrofoam here right right because these foam things you didn't see
these in the construction video These are the negative of the carbon
impregnated foam here and it allows us to just walk on it I guess they have no
function RF wise uh very very minimal reflection got it and they can hold
enough weight kalinam was in here with me no problem
wow you're gonna call them I don't like that he called himself out first his
nickname is Nick he gave it to himself yeah yeah okay but you'll have to
explain to me what's the usefulness of testing a 4G network from like four
meters away that's not realistic well effectively what we can do is we can
control the power levels that we're broadcasting at to simulate different
distances the way that these Chambers work and with the frequency bands we're
testing we need to be able to have the broadcast equipment a certain distance to the wall and a certain distance from
the device under test that's why I've got this kind of C shape here so we can
get over here this is where the broadcast equipment will be and then over there we're gonna have a pedestal
with the device under test how do we simulate things like obstructions
because those exist in the real world one of the cool things with that is we
actually have a fair bit of leftover foam including some of the flat lossy
absorber so we can position that in between the device that's broadcasting
and the device under test we can also bring in other larger pieces wood
framing walls a sheet of drywall if we wanted to to see how that actually
impacts things and I can tell you on millimeter wave if you have even a pane
of glass in between you in the broadcast antenna you'll lose connection
we go into a lot more depth about the actual construction of the chamber in
another video we're going to have that Linked In the description and if you want to hear even more about it Jake
Danes from the lab recorded a deeper dive that's going to be coming soon at Floatplane.com LTT coming back to the
outside world as outside as we get these days let's
take a look at our benchmarking situation it's never been a problem to
script performance testing for games that include canned benchmarks and some
of you helpfully pointed that out when I talked about how cool mark bench was
going to be because we could automate all this stuff
but what's not that easy is running pre-done repeatable benchmarks for games
that don't include Ken benchmarks well guess what we can do that now and I
would love to interview the team that has been working on it but Nick's on
vacation Jesse's shy and these two are on probation so
Tim will be helping us behind us we've got three separate benches running
through our Graphics testing Suite right now but the key night among you will
have noticed that there's a fourth monitor that's doing something called
OCR or optical character recognition why
do we need that when we could just run an auto hotkey script yeah yeah totally
Auto hotkey strips are dumb and we don't want to use those because if they run
into problems they have no way to solve them and so the way that we're moving
forward with developing the harnesses for the games that we want to test is
making sure that they're flexible they're reliable and if a new screen
pops up because of a new season update or something that we haven't yet caught
is is just kind of buggy we want to be able to click on those things reliably
and repeatably got it so okay that just changed why are we looking at that
monster yeah what you can see is there are some green boxes around various
pieces of text that it sees every screen that it shows there is a failure to find
what it's looking for it's looking for a specific set of characters or a specific
word to click on it next action and each
screen that we're looking at is it not finding it yet
pretty cool theoretically it's scalable too we're running three right now but we
can connect a whole bunch more and Adam said that we weren't going to talk about
this but I decided it's really cool we are going to talk about it what Jesse's
been working on mostly is taking this entire dump of recorded footage and
chopping out all the crap we don't need so we don't see any menus or any junk
like that it's just all Benchmark runs which is going to be super cool when
we're editing them down for you guys to see side-by-side gameplay yeah that's
the bulk of our work when we're trying to trying to get through an embargo or a
review of something and we're trying to make sure that that doesn't need to be
done anymore sick I noticed something else that's really cool this keyboard says recording
on it right now and my understanding is that it's red for a reason yeah so we
are working in RGB but we've got R right now
um the reason that we have R is because we actually found that alt tabbing in
some games was causing performance issues we were not getting repeatable
results by switching to mark bench starting recording switching back to the
game and we needed a way to know is that recording running rather than having it
on the screen which was also a performance impact so once RGB is
working you said we're going to have a progress indicator meaning that these
keyboards are basically acting as glorified LED strips and recording lamps
thanks steel series ah a wild time it appears we have
completed our first test print on our metal 3D printer and naturally we chose
oh
a scale replica of the LTT screwdriver
handle now we can't show you guys the inside of the oven NDA and all of that
noise but we can talk a little bit about our experience with the rapidia metal 3D
printer I see you did an end cap as well I see it in a completely different
finish what are we even looking at right now I printed both of these and did
vastly different post processes on these after it came out of our furnace
rapidia generally suggests sanding it before it even goes in because sanding
steel is a lot harder than sanding essentially clay
wait that's what it starts with yeah so
shut up that is so cool okay just a second here so so this is what you put
in and this came out yeah it's so much
bigger there's about a 16 shrink rate for the parts after they come out 16
1 6. you mean 60 that looks so much bigger that's a 16 difference yep
interesting when it's in three dimensions it looks a lot bigger than it
is so wait what so this is just a support
thing then oh my God look it's totally 3D printed supports and the steel is
just embedded in the clay yeah so it's it's
part of it and I use the term clay it's not really clay it's steel and a binding
material but it just it's a very similar texture to like a clay pot before it's
fired at this wow so for a bit of
reference this is a support piece that I printed for something else uh-huh break
that easy pretty much like it's nothing okay
now where's a metal printed support piece okay now you want me to break this
you can try don't do that
I noticed that you haven't actually assembled this into a screwdriver I
assume because it's difficult to press fit a shaft into did you think of that
before you started yes and since we're
not actually making a metal screwdriver at least to my knowledge
um what is the point of this project doing this project is building knowledge
within the team of how to use this equipment so when we need to use it for
either a video or for prototyping merch merch items we have the expertise and
don't need to rush to try to build the expertise when we want to shoot a video
in a week got it now tell me something is there a structural disadvantage to
this like can I just like is it just a hunk of stainless
steel or is it like other 3D printed plastic objects where the structural
Integrity of it is inferior to a cast piece
it is a little bit inferior in terms of like overall mechanical properties but
for anything we're gonna do yeah it's essentially solid steel not a
scratch can we even show like oh we can show this yeah we can show this oh cool
okay you're printing keycaps because of course you are
yeah I have one they're
there so this is what it actually comes off the printer as we have two nozzles
one that does the metal paste and one that does a support So for all of these
pieces the actual part you want is separated from the base by an aluminum
material which is essentially a ceramic otherwise it's going to bond together
and you are not getting it apart right to get this thing off of its support and
it had proper separation I still had to whack it with a hammer a whole bunch of
times sick are we doing a middle screwdriver
maybe oh yeah and then all the excitement I almost forgot to update you
guys we've officially moved in I've got procurement over here on my right I've
got Logistics over here on my left they're very proud of their new cable
ties that are color coded for different cable lengths no I it's a good thing
someone is that a bell is that a bell what that's the doorbell
that is an awful doorbell also it is getting awfully hot in here we actually
booked air conditioning for this Warehouse a year ago and we are still
waiting for air conditioning units so it's going to get a little stuffy over
the next little bit here RAM storage now
that's a creative use of server rack shelves ah
my intention was to introduce you guys to our community manager and talk to the
social team here but I guess they're all on lunch so cool I'm sure glad we
delayed this shoot from after hours yesterday to today so that everyone
would be here anyway the point is they only just moved in why because of this
the server room that is next door to them it was so freaking loud in that
room that we had to add Sound Treatment to all of the walls and ceiling of this
room just to make sure that it would be quiet! enough so you could hear yourself
think over there unfortunately even after we added our three layer solution
of sonopan Rockwall and duveteen it was
still loud and it turned out there was some annoying buzz from one of the
Transformers that's directly above them I bet Jake that we would actually have
to replace that Transformer he bet that we could just use some isolation pads
under it and long story short I owe Jake two lunches it's pretty good in there
Old Trafford here this is where you'll find the Mac Address folks and Jake
bellavonts is usually here our ShortCircuit Channel lead so this is what I'm
talking about we're trying to show a building full of people we moved in with
and the no no you're good you're good Sam go go lunch lunch The Writer's area
is fully moved into Jake and James haven't taken over that office that I'm
sure inevitably they will take over at some point Emily's desk Tanner Jordan
what are you working on what the hell is this
not this that what is that that's not working right now what the heck Adam and
Pluto you know yeah I I know where my office is it's
still very not set up um
as it turns out I have more important things to do than arrange things in my
office let's go figure
look I mean yeah I have an assistant but it turns out he has more important
things to do than arrange things in my office where the hell is everybody
well Brandon Dickerson's space is here
he's set up this like neutral gray over everything so that he can do display
testing I was told that these two Scopes
cost the same as like a decent car
um they're for color
I'm sure Brandon's gonna have a big update for you guys once he's got his
proper space set up out in the warehouse but at least this is getting us some
data in the meantime and he can work on his testing methodology
what is this secret for you is this PoE
powered I think it's security cameras
security camera what no I think it's going to be security cameras it's LTT
store okay what is this thing what is the point of it ubiquity makes a display
now um it's like a PoE power touchscreen oh
okay for what I don't know you can show
the cameras but you can upload any Android app I was thinking for LTX this would be like a really dope way for
people to be able to just like pre-brow stuff oh yeah oh I know for some of you
that must feel like not enough progress like what's going on this is taking
forever to get Labs going but the reality is we're taking the time
that we need to do it right I mean think about it app slash roaming data wasn't
built in a day that's some computer humor for you and I'm gonna follow it up
with this segue to our sponsor vesi looking for a new pair of kicks to wear
during the summer pick up a pair of vessies but hey Riley aren't vessi's
only good as rain shoes which is a previously existing phrase apparently
nope vessey's dimetex technology is
designed to keep their shoes kicking it animal style rain or shine I don't know
what I'm saying check out the boardwalk slip-on sneakers with a classic design
fit for summer they're also made to let sweat and heat Escape keeping your feet
dry oh and on that note of course vesi also claims their shoes are 100
waterproof an Eva midsole cushions your feet without added weight for unmatched
Comfort during prolonged use these puppies are ready for the beach check
out the vessey boardwalk and other styles at vesi.com Linus Tech tips and
use code LTT for 15 percent off your entire order
if you guys enjoyed this video why don't you check out the one where we shoved a
computer into an environmental chamber to see how much we could overclock it
