 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 got to get HDMI out there introducing this Jank cheap wire that we found in a bin we're gonna use this Also the HD link HL 24 to send HDMI Well, it's not two miles, but however long this wire. We found is speaking of wires none Corsairs 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 gonna 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 HD link HL 24 sender So this is the base unit. He's got our video source a Video source a Video source a HL 24 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 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 gonna 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 then that That four by four really is gonna smoke me if it falls Guys don't bump that I don't know why I'm doing this. I'm just trying to figure out what's going on I'm just trying to figure out what's going on Why does he run like that? Does it go on the black water the red one black main screen turn on? Yes, James I've got a signal Yes, yes with this technology the sand people could watch television now Through a video of a screen of a YouTube video that we have got some serious compression issues here Marquez's 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 gonna 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 Sure Linus 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 gonna 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've got this line of spill tips Check this out. Look how much water is on the counter already. Just put that on the floor Is that one vented? I don't think it's vented. No, it doesn't need to be that's fine. You gotta You gotta spread it out a little more though I think this video already has enough of salt in it. Wait, what are you talking about? Okay. Okay Is that enough salt? Jesus line No, no, I'm just regular Linus. You're thinking of my cousin He lives in Mexico. Hey, there's Linus Are we getting the salt down there? Wow, you can really see the salt move in there. It's a salt migration It's like basically opaque over here This hasn't dissolved at all. Look at that Oh lordy. We 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 Giving us million times better results. I'm gonna go ahead and do that I'm gonna do 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 gonna take it to another level If it can pass through a hundred percent water Plus some salt then it should be able to pass through 60 percent water Laser James Oh, come on No, just put out your hand. Oh, 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 So let's try it on like the ring 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 Okay what Come on. 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 Uh 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 hl-24 could be used for that as well.
