HDMI Over...The HUMAN BODY?!

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 by 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 hundred and seventy-five 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 Jake cheap wire that we found in a bin we're gonna use this also the HD link HL 24 to send HDMI Watts 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 gain with no compromises and no wires check them out now at the link in the video description [Music] 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 hl2 for 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 mind bigger than his and a monitor because I have to power a monitor I need to find some cover here that 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 black hole there that taw about four by four really is gonna smoke me if it falls guys toe pump why did you run like that does it go on the black one or the red one black bean screen turned on yes James I've got a signal yes yes with this technology the send 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 marques is uh Chris penis 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 with you look up 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 tape 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 10-foot tube and you might be thinking to yourself this is probably some kind of weird drinking game with like the but but it isn't not yes not on camera now we won't need a funnel no no we got this here - ill tips check this out check how much water's all the counter I put that on the floor that's not what invented I don't think it's been did you know it doesn't need to be it's fine you got you got to spread it out a little more though I think this video already has enough assault in it wait what are you talking about okay okay is that enough salt Jesus luck no no I'm just regular like this you're thinking of my custom Mexico are we getting the salt down there wow you can really see the salt move in there some salt migration 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 mines leaking now to this million times more conductivity is not 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 Lincoln 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 themselves then it should be able to pass through sixty percent water Laser James split down let's try it let's try this one on liquor 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 guess what I'll bow a bow I'll shake hands no 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 to 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 HL 24 could be used for that as well so nice within a niche but definitely really cool to check out and you know else is cool to check out I fix it I fix it as leading the charge on DIY electronics repair they've got over 25,000 free guides for taking apart repairing replacing batteries in your electronics and they've also got their fantastic lineup of tools including their pro Tech tool kit which is now just 5995 the Pro Tech tool kit includes their 64 bit driver kit a wide variety of prying tools and sputters and picks as well as ESD safe tweezers a suction cup for moving displays an ESD safe strap and more and the best part is it comes with a lifetime warranty so stop paying people to repair your devices learn to do it yourself you'll save some money and you might even have fun in the process visit ifixit.com slash Linus to get your protec toolkit today we're gonna have that linked below so thanks for watching guys if you just like this video you can hit that button but if you liked it hit like got subscribed maybe consider checking out where to buy the stuff we featured if you have an application for it at the link in the video description now while you're down there you can check out our merch store which has cool shirts like this one and our community for oh no we don't have shirts like this one maybe we should do like a floatplane shirt ah and our community forum which you should totally join
