okay so we've all been there you need to run a video signal like really far away
but you don't have a long enough cord well easy right just
buy a longer HDMI cable wrong
if you need to go more than about 40 45 feet you're gonna have to get an
expensive active cable or you're gonna have to get a booster from someone like
sewell direct that'll give you another 175 feet but what if
you lived in a world where your shed was like two miles away first of all good on
you great property you got yourself there second of all we gotta get HDMI
out there introducing
this jank cheap wire that we found in a bin
we're going to use this also the hd link hl24
to send HDMI well it's not two miles but
however long this wire we found is speaking of wires none
Corsair's line of unplug and play wireless peripherals lets you game with
no compromises and no wires check them out now at the link in the video
description
so let's gather up everything we're going to need for our demo first my
lovely assistant james thank you james james is equipped with
aside from a stunning intellect you really wouldn't know looking at him he's
got the hdlink hl24 sender so this is
the base unit he's got our video source
a wet lg gram because it's raining today
he's got a battery pack to power our hd
link sender outdoors because we're doing this outside for some idiotic reason and
a big spool of wire for my end i'm gonna
need the extender receiver unit
another battery pack mine bigger than his and a monitor because i have to
power a monitor i need to find some cover here
ah needs to be bigger all right
i think there's really only two words to describe what i've done here
stable and genius
there we go let's go to the other end only
one small problem our wire doesn't go to the shelter
so these just look like kind of standard almost like a speaker connection so you
can either just go through the side like this or you can use a banana plug
so you can tell it's already engaged because of this blinking green light
that means it's sending data okay there's another light on the other side
that's going to blink when it's receiving enough data okay
all right trudging through the wilderness
no sign of civilization
anywhere but i gotta watch my tv
and thank god i got this wire oh man that uh
that 4x4 really is gonna smoke me if it falls
guys don't bump that
why does he run like that okay
does it go on the black one or the red one black
main screen turn on
james i've got a signal
yes yes with this technology the sand people could watch television
now you can probably even tell through a
video of a screen of a youtube video
that we have got some serious compression issues here
marquez's uh crispiness is not up to its
usual level of crisp so here it is working we've got video
and audio this is at 1080p 60 hertz which is pretty darn impressive
over a single wire here but it should be noted that i wouldn't recommend a
solution like this for gaming for example it's fine for
watching tv but there are going to be some compression artifacts if you look
up close there's some color depth loss and most importantly there is some added
latency so the compression that happens in the box on that end and then the
decompression that happens on this end does add a significant delay to the
video signal okay now you're probably thinking to yourself
sureliness and also james pretty impressive demo but this seems
like fairly ideal wire as far as wire goes
well first of all no not really because something insulated would be a little
bit easier to work with we had some issues with this making contact with the
wet ground causing us to have some signal drop off
and second of all to prove that you could really use not
just any wire but any conductive conductor we are taking it to the next
level this is water regular
tap water and we are going to send an HDMI signal
through it so to conduct
this phase of our experiment james took the included banana plugs and then
electrical taped them to some cable that we had lying around and all we've got to
do is plug this into here
run my end into the ordinary tap water
no it's working
so now that we've got the laptop and the monitor a little bit closer together
this gives us a better look at the delay between the source and the output
it's not that bad but like we said before it's not
something that you'd be able to game on but of course if we can get a video
signal running through regular tap water
over a span of about six inches
then with salt water which is about a million times as conductive we should be
able to go much further shouldn't we all right james
let's do this so we've got here
two water cooling reservoirs
and a ten foot tube you might be thinking to yourself this is probably
some kind of like weird drinking game with like the butt
but it isn't
not yet not on camera no we won't need a funnel no no we got this here line of spill
tips check this out check this out how much water is on the counter put that on
the floor is that one vented
i don't think it's vented no it doesn't need to be it's fine you gotta um
you gotta spread it out a little more though i think this video already has enough
assault in it wait what are we talking about okay okay
is that enough salt jesus
no no i'm just regular Linus you're thinking of my cousin
he lives in mexico
are we getting the salt down there wow you can really see the salt moving
there it's a salt migration
it's like basically opaque over here this hasn't dissolved at all
look at that
oh lordy saturated the entire volume
so we want to see 10 feet
of HDMI through water oh crap keep that away from the laptop
that will kill it for sure oh mine's leaking now too
this million times more conductivity is not uh
giving us million times better results i was thinking we could do HDMI over the
ocean oh we're close we're close
we just need more salt
sticking them further in did not seem to
actually generate better results
okay should we shorten it just a little bit more
wait wait oh
it's so close
still no clean signal
come on i thought for sure a million
times more conductivity okay here's an idea
oh crap that wasn't the idea
what if we just go right into the tube maybe something about the reservoir
that's a lot of blinking there we go
hey we got it 1080p
60 hertz five feet through a tube now for our last trick
we're going to take it to another level
if it can pass through 100 water plus some salt then it should be able to
pass through 60 water
laser james
oh come on no just put on your hands no they're
salty enough no
i had a cut it's like split now
let's try let's try this one on like the ring
will that work
there it is hey not bad there it is there it is HDMI through humans
yeah let's get that thumbs up in there yeah
what i'll bow i'll bow
i'll shake hands no oh it's weird
okay so that was a lot of fun but if you've stayed for this long you probably
deserve some kind of explanation as to
legitimately why this exists honestly
it seems pretty niche to us too for most
long distance HDMI applications you would probably use HDMI over Ethernet
since Ethernet is available in all kinds of different
configurations for indoor or outdoor use it has multiple conductors and it also
has quite a significant range but in an application like a digital
signage billboard out in the middle of absolute nowhere literally two miles
away from the source
this could make sense another potential pitch is to use them as an emergency
backup in the event that a cable gets severed and you like
absolutely have to connect the two ends together
the hl24 could be used for that as well
so nice within a niche but definitely
