it may not be the DIY more economical
environmental chamber that I asked for but with adjustable temperature and
humidity it'll allow us to simulate the environmental conditions just about
anywhere on this beautiful blue orb and that's a good thing because if my tablet
breaks then damn it I want it to be for a good
reason not because I had the audacity to live somewhere hot and tropical like
here's a good reason so I could get this segue to our sponsor

environmental Chambers are one of the most is
environmental Chambers like this one are one of the most important pieces of
equipment in a manufacturer's Arsenal and the reason for that is even if
they're not building a rugged device designed for Arctic expeditions
even devices that are destined to spend their lives indoors can be subjected to
vastly different environmental conditions I mean take something as
simple as room temperature that is culturally dependent and room
temperature can be as high as 28 degrees Celsius in Nigeria and minus 28 degrees
Celsius in Europe in the winter in an
energy crisis that is where the
sch-512-4 comes in with our humidity
range extension option this bad boy will fit so much humidity 98 to be exact so
it'll go all the way from 5 to 98 relative humidity meaning that we can
simulate environments as demanding as southeast Asia where as we alluded to
before Electronics failure rates can be as high as two to three times what you
might find in a more moderate operating environment of course humidity is not
the entire story and we want to talk about temperature as well this is a big
one because while humidity is going to affect a device's ability to work at all
or not work at all temperature could
affect its efficiency say a GPU for
example I need a GPU whether it's something as small as finding that a
particular GPU runs three percent slower in Texas than it does in Oregon or
something as big as finding that a mobile phone manufacturer has a big
battery controversy on their hands because at low temperatures their
battery life Falls far lower than the competition this is going to help us
root it out and while we might not be looking at the most interesting side of
it there are certainly some things we can talk about back here for starters
there's power this bad boy calls for up to 40 amps of 208 volt single phase
power and Peaks at 8 000 Watts that allows it to go up or
down five degrees in temperature per minute that's all handled by the HVAC
system here which based on the size of the condenser could probably handle a
small apartment if it didn't need to go up and down five degrees a minute moving
down we've got another optional accessory or wait this can't be optional
is it like a bigger one or something that's the humidity control I guess if
you just want to do temper control you wouldn't need this right correct cool
they make it very clear that you may not use deionized water you must use
demineralized water and I guess that's just to keep it from getting schmooed up
inside or is that to do with the actual Vapor it'll be due to not getting schmut
up inside thank you our water up here it's nice and clean so hose it is not
really no this is this is where the liquid goes it looks like there's a
small filter on it and then you hook it up to the water inlet right here which I
think we've got to open this up and have a look right like did we sign some kind
of NDA for this thing double blue so okay cool yeah you know what's funny is
you make your way from Etsy to consumer electronics to Scientific equipment as
your price goes up the diy-ness curve kind of looks like this yeah yeah
anywho it's the opposite of the Dunning Kruger curve all right here's our water
inlet here's a something yeah it's insulated
thanks so well there's some wires yeah
what this likely is is this is going to be the heater slash cooler for the
actual water for the humidity control in order to make sure that we hit an
optimal temperature gradient right cool and then this looks like it's sleeved
like it might be a temp probe or something yeah those look like thermocouples cool this looks very hand
built I think they all are actually hand assembled yeah I mean yeah
ooh gn2 Purge yes we have a gaseous
nitrogen Purge which does
it gets everything that isn't nitrogen out of it oh I think it uses gaseous
nitrogen to purge right so that would get everything that isn't nitrogen out
of it okay yeah not strictly speaking behind a door but
this is our desiccant system now what we
just have to like keep refilling it with like desiccant crystals or I mean we
have an apple Supply them Yo Logistics can you guys just save every desiccant
package that you get from now on actually no this is a closed system we
shouldn't have to refill the desk again uh frequently by any means so how does
it desiccate how does it desiccate well let me pull out this handy manual
so uses this to control the humidity this is our air dryer yeah humidity it
delivers wet air doesn't excess Purge uh so it'll be part of the gn2 so I'm not
gonna have to like buy nitrogen cylinders and crap uh
that's a good question oh speaking of nitrogen cylinders one of the features
of this chamber though I don't actually see any way to do it is that you can
hook up dry ice or liquid nitrogen to
vastly reduce your pull down time do you have any idea how that works our model
didn't come out with it with that however it is an optional add-on that we could talk with AES and get sent out oh
so yeah okay we we don't need it though
five degrees per minute is pretty good and if you're complaining about a
nitrogen tank you really want to store dry ice now from what I heard AES
included an Easter egg for you really they did oh I found it
thank you honestly I assumed it was whatever was inside here but that's amazing
um like shout out AES by the way I we
did pay for it right yes we have but I'm pretty sure we got a deal on it because
like so many scientific equipment manufacturers these guys are like wow
it's so cool someone other than a manufacturer is finally doing this and
have uh decided to help us out which is really cool not just for us but also for
all the consumers who are going to be more educated thanks to this gear that
is a lot of glass and this is really
cool we actually got what is supposedly like filming grade glass or something so
if you go on the other side David it should be no problem for us to film
things that are inside the environmental chamber which to my understanding is not
a standard feature would they typically have no glass at all or they could have
oh it would just happen it would just be a solid plate wow this seems like really
fancy like does this triple pained it's quadruple pained
now this is cool they've actually got oh
I guess this is just a grounding strip or something they've got these strips on
the outsides of the glass that seem to be soldered to something
actually I think those might be the lights oh shut up there's lights so that way we
can film through once those lights are on it should be a clear picture through
the glass that's so cool small correction apparently these might be
heating strips because the glass is heated to prevent condensation from
forming on it correct that's freaking cool yeah these guys went all out with
making sure we could actually film through here oh amazing now the kinds of
things that we might end up filming then I think certain things are obvious like
phones I mean you could do a whole Army
of phones like is that the kind of thing that we would do oh yeah I plan on
having 25 devices under test at any given time for the most part so we're
going to be able to have 25 devices in here all at the same temperature we'll
be able to record their battery drain at different levels now tell me something
do you need to have them plugged in in order for you to record all that diagnostic data or everything Wireless
everything over the network that's
look in the back we have pass-through wait that stays open and it still stays
at the right humidity except shut up but there's holes yep I mean you would at
least plug them if you're not yes and of course the beefiest Environmental
they're foam so you can keep your cables them oh that's so cool this is the most
satisfying squishy toy I want to ask
them what this is made of so we can do like a stress ball for LTT Store feel it
that looks like a neoprene composite this goes in here
probably on the outside for our user friendliness these will be especially
useful for categories of devices that cannot be operated wirelessly like say
for example a PC power supply the home for the environmental chamber is
actually going to be right next to our power supply testing unit so I think the
idea is that while we can't necessarily run efficiency tests while it's wait
yeah how are we going to do that because we'd want the cables to be the stock
cables plugged into the PSU tester like is that going to reach
we're right next to it so yeah realistically we could
um but but I believe that we are going to have some longer cables from the
chroma that'll plug in okay but then we wouldn't be able to evaluate efficiency
at high temperatures we are going to be able to
um that's a good point Gaines is the
mobile guy in the long term so realistically that's not going to be his problem but it is one that we are going
to have to solve because the efficiency of a power supply can be dramatically
different at zero degrees compared to what it is at 40 degrees both of which
are perfectly realistic operating environments this makes sense then you'd
have your pass-throughs for the top shelf and your passengers for the bottom shelf and while you can put the Shelf
absolutely at any height that you want probably I suspect what we do is end up
with it kind of in the middle most of the time yeah I would say so you could
probably if we put a base plate down fit six laptops in here if you put them if
you pivoted them 90 degrees yeah that could work so that way they're side facing would you get enough air
circulation if you had a solid itself though you wouldn't have to fully cover
the shelf so you just make sure underneath the laptops it was flat
oh that's still getting dangerously not that real world because you know two
inch buffer all the way around it you're fine it are you well let's find out well
yeah I mean I guess we could test that and that's why we're here yeah right
okay fair enough I was told this could be used to test desktop computers not
this stuff hold on see look perfectly normal gaming desktop doesn't
even fit in my environmental chamber Gary I know we just cut a little here oh
my God yeah is that how you did things back at ASUS absolutely in all seriousness
though guys this is a much more typical mid-tower size computer
which is this a threadripper pro yeah is this
new threadripper Pro what new
oh okay I thought it was like very new but tell me something this thing could
easily be kicking a thousand fifteen hundred watts of heat out into the
chamber if we tell this thing cool it down we're probably not going to get
five degrees a minute out of it no so your pull down or your rise up rates are
going to vary depending on what's actually in there sure you've got a thermal load right yeah sure empty five
degrees per minute got it with this in here
oh I know what this is as1 connect we
got an extra system that allows us to connect this thing to the network and
it'll log over a span of like years or
something like that like every humidity every temperature how often does it log
do we know I don't know the exact polling rate but
it is I believe it's just logging all the time that is that is an incredible
oh my God yeah what the hell am I
looking at you weren't expecting that when you open it up were you I was expecting something but that's beautiful
you can tell they take seriously you
know what I'm saying yeah proper Cable Management so circulation Motors
compressor we've got heat power supply humidity heat here's our window heat if
we wanted to trace those wires yep now we can't turn it on today unfortunately
uh because we don't have the power plug installed yet but what I can do is
further demonstrate the size by showing that we can fit a whole human inside the
environmental chamber how long would I last in here at the extremes of what
this chamber can do not vary but we could make it very comfortable
you know man I could be so comfortable
in here if it was working right now we
could keep it at a healthy 25 degrees just like I'd be comfortable telling you
