If it doesn't work out to use it for other things, they'll lose the cost of disposal. Paying a company to come and take that away for disposal would not be cheap.
I'm like 75% certain that was the chamber I disassembled when I was in college working in a microelectronics lab, fun fact the dust that foam creates gets into your sinuses and makes your mucus black for weeks in the disassembly process.
@Mouseythegreat nah anyone whose ever been grinding, cutting, or sanding knows if you don't wear respiratory protection or do it with good ventilation your mucus can and will turn whatever color the material is (bc your mucus will trap the particles you're breathing in)
I spent years working in the space industry and we had chambers with similar foam (usually significantly larger, like 100m x 40m x 40x with foam pyramids ~1m in size. The tips would blacken/smoke when testing extremely high power RF links such as geostationary communication satellites (Eurostar 3000 bus) which normally have to transmit huge distances with relatively focused beams. All that power going into the foam caused them to smoke/melt. Perhaps these foam panels were used in a similar high power chamber.
A friend went to a small technical college that was expanding in to electronic technician programs. They hired a professor to lead it and part of what he said they needed for the courses was an EMC chamber, but the college refused to use contractors that were experienced with such installations and used their general contractors instead who didn't have any idea what was required. They did really dumb stuff like cut holes for the sprinkler system. The professor when demonstrating the chamber to the students had his phone ring and had to explain to the group of students why that meant their EMC chamber was just for show and didn't actually work.
Our college has countless labs. One of them directly above a lecture theater In that lecture theater, you'll be foolish to think you can get a cellular signal. WiFi works fine because there are access points in the room.
That is an egregious act of stupidity on the colleges part. Oh let's spend 40000 on a sound proof chamber. What?? 10k to install? I think well just take our chances and risk 20 years of students having access to a real emc chamber. Wont affect our tuition prices or accreditation anyways
I'd say it's in no way ruthless to charge these people for storage. You contacted them 2 months ago and they ignored you AFTER sending you the "wrong" thing, it's 100% on them. A warehousing/logistics company I used to work for would've charged a minimum of $15-$20/week/pallet and that's if they were being nice.
I work in telecom and we are handling this kind of issue with a GC, having stored equipment in their warehouses before the customer (US Carrier) cancelled the site. They're trying to charge us $20k USD for 1.5 months storage of 2x pallets of hardware (antennae and modems/cables). Shits bonkers
I'd imagine the likely result from that, would be more ghosting as they simply ignore the invoice. At which point you'd probably be forced to try and bring them to court to get actual action enforced upon it. Charging them a fee to which they didn't agree to might not hold up in court, and whilst there's surely some general fraud charge you could pin on them, it may not be worth the legal fees, time and hassle to pursue. Or maybe it would be plenty worthwhile. Lucrative even. I dunno, I'm not a lawyer. Please don't sue me. Either way, Linus is probably far more concerned with just doing fun tech geek stuff, so long as he's not actually lost anything.
As radio ham I'm glad someone is taking notice of the spurious emissions a lot of devices are emitting. Despite having FCC certifications printed on their labels. You should see the mess it is in urban areas. Switching power supplies are the main culprits. I have to use a cross phase interference eliminator to operate my radio now.
@@thesocker7920 TL;DR they are very cheeky with LTT. Had LTT build them a very huge unnecessary pyramid computer and changed what they wanted done on purpose several times just to mess with them. Bad LTT publicly said how annoying they were being (all in fun mind you). I suggest looking it up, pretty funny overall
This was a win win for them. They now have new contacts to work with and they made the money, they would have spent, back in just a couple of videos. Not to mention that the foam and framing are still useable for another project
Yeah, today's title annoyed me a little. They've been using Clickbait titles for a little while now, which I can't blame them for because it works, but todays title is just plain lying. Still love their content, but I hope they don't start following the trend of twisting the truth so much that it becomes lying.
They chose the clickbait of course. That said they did try to sell the stuff fraudulently to Linus so he is free to say whatever at this point. Whoever did this probably wanted to be rid of the stuff as much as it wanted to make money off it. It's great Linus didn't pay in advance.
I love how Linus is all "they shipped us all this stuff, but they haven't taken payment?" "Let's make a video for content so we can profit off of it anyway" LOL.
Linus is a consumer like everyone else, and he wants to use his platform and resources to hold the companies accountable for the bs they tell everyone.
This feels like every HVAC contractor I had to deal with. They knew every one in the industry locally. It got to the point that every time I, or my boss,found something used online: I would send the info to a contractor plus $100 Target card just to get the real deal so my boss wouldn't decide to buy used HVAC stuff. Good job making lemonade out of lemons from a decade ago
$45,000 is great deal if you got what was pictured. I have spent many weeks in EMC chambers testing products. Some of the chambers I used are well over $1,000,000. The hourly rate to use these chambers can be $250 or more. I hope your engineers like EMC testing as most do not. It is like watch paint dry if you have no issues. It can quickly becoming very challenging when you have issues. It is going to cost a decent about of money every year to keep your equipment in calibration.
there was no deal here. someone needed to dispose of a shit load of beat up, stained and old foam and their answer was to hopefully trick someone into buying it as that would have been cheaper than proper disposal lol
That carbon electron field graphic represented energy levels, electrons don't slide smoothly based on the energy in the system, but they nearly instantly jump or fall to appropriate energy levels when the system reaches the threshold.
Love the concept of incompetent scammers. They send you their bogus product but then forget to collect the money and then are too embarrassed to try again 😂
Quite competent actually. They got rid of a whole heap of worthless junk for the price of transport, instead of having to pay the price of transport and commercial dumping fees. Of course maybe they had the stuff in the first place because someone did the same thing to them - which might mitigate that competency assessment.
"Hey, I can get rid of this junk for you if you pay me x dollars" Proceeds to not sell it but gets rid of it and gets the money through other means most likely
It's weird seeing the same foam that we use at my aerospace job in a LTT video, but it was actually pretty informational for me since I see it around a lot but since they are not in my department, I didn't know the use. Very cool!
@@drinkscoffeealot I was busy being 8 years old getting my Tonsils surgically removed in 2010 lol. But nice, you still with AMD 12 years later? Or did you go green at some point
You mentioned that the one you bought was carbon-impregnated and not Ferrite-impregnated because of cost and lack of need for the frequency ranges you're working with, but the advertisement you showed said that it had ferrite tiles strategically placed on the testing-side wall and floor.
FYI you can remove creases from some foam using a hair dryer. Your interns may be able to straighten them up. I'm curious how much of an improvement new foam would be, I doubt it will be a big difference. Free is a good deal (you are not developing cell phones).
Hey Linus, the model train could be a throwback to the arctic fire truck, one of the most popular videos on your main channel. Would be an awesome addition.
honestly: done right the train could serve a legit purpose. Some people place mechanical clocks into the EMC chamber to verify that the video stream is in fact a stream and not a frozen image. Now, you can argue the EMC cameras don't do that crap, but when you test cameras, looking at a screen that is looking at a screen... yeah: Placing a Stirling engine or drinking bird into the EMC chamber is no joke. The train set off course is electrically and optically nosy - but... place that in the camera lab as a literal moving target and... well: It is a legit focus tracking test that is somewhat repeatable and fair.
It would probably cost them more money to take it back, store it, and try and find another potential buyer who WON'T be turned off by the broken tips and degrading foam, than it is to write the whole thing off as a loss.
i love this channel, keep bringin us this gerat content......you guys investing on all this shows just how committed you are to all of us, for that thank you. edit: please never cut something whiles holding it on your knee specially like how linus cut the foam...it legit made clutch my a**.
Yeah that seriously freaked me out, I mean obviously they wouldn't post anything that has that type of accident in it but still, cutting over your leg like that should never be done.
Yeah I kinda noticed it but looking at footage. He’s forcing it way too much. It had a lot of force when it launched out. Had he hit his leg, it would have been bad.
Dude, you got all the parts to build your own highly sound dampened room, I'm kinda jealous. I wonder how quiet it will be when it's assembled, I've heard stories of special chambers that when you walk into them you can't hear your own voice.
You were not far off gashing your thigh open with a Stanley and then decided to test a foam blocks fire resistance when you're sitting underneath a mountain of the stuff. I thought I was watching that show "destroyed in seconds" for a minute.
The only part of this video I had to rewind to hear again was when (I swear) he said, "double set of Gerbil Ball Bearings" (11:55) when covering the MSI card. Say what? Those poor gerbils.
I worked some time in an company which tested testet stuff on electro magnetic compatibility. we often heard Russian AM Radio in Germany probably by a atmosphere bounce (it depends on the weather) even in the even more expensive chambers xD they got some pretty strong radios antennas over in Russian haha
The dust from that stuff is pretty toxic I wouldn’t roll around in it. Also if it catches fire it’s super hard to put out. We have sprinklers on the outside to keep the rest of the building from burning down not to put it out.
Pretty psyched you're going to do camera reviews. In the last year I have utterly rekindled my photography hobby by way of work asking "hey do you know anything about cameras?" and moving that into basically being the sole photographer on any project. SURPRISE, there is a lot more to photography than your cell phone has led you to believe, and if you can add "emotion" to report photos, that only helps. In this process, I have heard SO MANY TIMES "why not just use a phone...". There are many reasons, and the deal breakers aren't even photographic. But then I got to thinking, I *have* old Androids going back several years, and on looking up their specs, they should produce "identical" photos. My hypothesis is that actual camera quality from flagship phones hasn't gotten better since roughly 2015, because physics. Just software has improved photos beyond this point, and is that even taking a photograph?
I have bad news for you; the use of foam for sound insulation is a well sold myth; it does not work. It does do "something" to the acoustics of a room, to be sure; but it does not "kill" sound reflections; it merely diffuses them. The difference is that while a naked cement wall reflects sound like a mirror reflects light, and a thick fiber-glass covered wall absorbs sound like black telescope interior paint absorbs light, foam acts like a light gray, matte paint that doesn't reflect specular-ly, like a mirror reflects light, but that merely disperses or randomizes the angle of reflection, like matte materials of any color or shade do to photons. If you need to know why foam is not a good sound absorber, think of it from an energy point of view. When sound waves try to traverse a space full of glass fibers, it is, at a microscopic level, like wind trying to pass through a kilometer thick jumble of heavy metal wires, where each time it hits a wire, the bad aerodynamics of the wire cause turbulence and its associated loss of energy (wind energy conversion to heat energy). Thus, a thick layer of fiber-glass causes enough microscopic turbulence to convert most of the sound into heat. Foam, on the other hand, is not as heavy as glass, and not as dispersed as fiberglass within a volume. It partly reflects sound, and partly refracts it, but in neither case does it convert its energy to heat; thus the sound persists, only having been reflected at odd angles. The final result is that in a room covered with fiberglass, you clap your hands with your eyes closed and it sounds like being in the middle of a vast field with no walls. But you do the same in a room covered in foam and it simply sounds like you are in a room with walls covered in foam. But be warned, this post will probably attract heat from ignorant audiophiles, self-proclaimed sound experts, and foam pushers alike; they are some of the worst people in the planet, together with socialists, fascists, religious fanatics, skeptics, politicos and tyrants.
OMG did anybody else cringe at Linus cutting that stiff foam DIRECTLY TOWARD HIS INNER THIGH?!?!?! JerryRigEverything needs to teach him how to use his knife.
I know in the USA, depending on state residence, if something I left in your residence for 90 days and you can't get ahold of the owner than you claim ownership by default. If it works the same in Canada, than you just got that foam for free. I'd definitely inspect that stuff for bugs before installing it anywhere since it was outside for some time.
I find that restarting my phone usually causes it to give an accurate signal reading. The fact that it normally doesn't drives me insane. How companies get away with charging for 5g, that they don't actually provide, is a clear sign of corruption.
In the interest of self preservation. Maybe you shouldn't cut anything in a way, that could cause a razor to maybe cut into and across your FEMORAL ARTERY! (this would be during your internal foam demonstration) FYI, The average bleed out time is 2-5 minutes. While the average EMS response time is 7-10 minutes. Soooooooo...... Stay Safe
For a moment i thought Linus was gonna cut an artery in his leg...NEVER cut towards body parts, especially those containing critical organs and arteries!
This is signal toward -or away from the device? I would love to see the panels flipped, to block more incoming and see if anything really changes, or if orientation is not that important in this case.
