They even pulled the ultimate power move of a sponsorship. Not telling the guy his EM chamber is free. Linus literally states that it cost "thousands of dollars" before the re-take of "Whoops we got it for free 🤷🏼♂" Honestly that made it the most memorable sponsorship I have seen *anywhere* in a long time. But I'm also not in the market for a EM chamber.

Been around these things too many times. If you think this chamber itself is something worth then think again. Kudos for business acumen of this company installing this chamber for free 😂 this is like drug dealer giving you first time free. Only accessories will set you off hundreds of thousands like all rotational tables, myriad of antennas, etc… then all equipment which will probably take few mil. And then salaries of people who actually know what they are doing. This is the reason why you don’t see this kind of setups even in very wealthy companies. All is nowadays outsourced to specialist certification establishments.

Those two people, if they're in the market for it, are the kinds of people who have probably been tearing their goddamn hair out looking for a company that can just do this one goddamn thing correctly. And seeing it done correctly is often a lot more than you tend to get from most businesses like this. Usually you get a spec sheet, some technical video full of roses and spit polish, maybe a written review from somebody you've never heard of... that's it. Industry folks usually figure out which companies to hire based on who their peers are hiring. In competitive industries, they'll even keep that info secret because they don't want anyone else knowing about their suppliers. So a sponsorship like this could mean bagging some big clients.

My only rule for a router is no Broadcom chips as Broadcom has bad support for things like OpenWrt. I found a nice Qualcomm router which might I add is very overspeced called the DynaLink DL-WRX36, it is a WiFi 6 router with 1, 2.5G WAN port, a quad core Qualcomm IPQ8072A, 1GB of ram (doesn't sound like a lot but many routers have wayyyy less than this), 256MB Flash (again, might not sound like a lot but many routers have less), has OpenWrt support and have been running it stable for months on that (even though it is still on a snapshot release), the only caveat is that I would not trust the default firmware that comes with it just because the company is unknown so I would recommend installing OpenWrt and the most important thing (yes, even more important than these overkill specs) is the device uses Qualcomm and not Broadcom, I made the mistake of going for an Archer AX21/AX20/AX1800 (yes, Web UI, UART, and sticker on the bottom all said different model numbers) and it was painful, Dynalink has been working beautifully

@@Spushed Honestly, for most of that, just unplug any external cables and disconnect any antennas and it'll probably be fine. If you want details, well, they're actually a little hard to find precise details on what an EMP actually looks like and you start running into needing actual RF test equipment to figure out how good your enclosure really is. Also, exactly how bad an EMP will be in your precise location is a REALLY complicated question, even if you have the rest of that. RF engineering isn't called black magic for no reason - things like geometry, materials, and a whole lot more matter alot. A metal container will probably help (assuming it has no wires running in or out) enough, but most devices are designed with quite alot of tolerance to damage from high frequency RF. It isn't done for EMP protection, it's done for electrostatic discharge and EMI regulations, but for an unplugged device during EMP, that's really the parts you worry about. The low frequency parts of an EMP are mostly a worry for stuff with long wires or connected to the grid (which is long wires) which can act as antennas at those frequencies.

@@ccoder4953 yeah our issue was always the accuracies that we needed... frequency response/flatness was a specific one that was always tough when you went cheaper and more portable. Putting our consistent -10 DB signal in and then checking it you know every 200 meg they would all drift really badly at some point or another in the spectrum. If you just need one to do basic checks and looking for harmonics or signals you can get away pretty cheap. We rarely needed absolute RF power accuracy because every test we did needed an accuracy that required us to use a thermistor or power sensor but then we had to rely on the s accuracy to verify a signal generator all the way out to fifty for example. I'm guessing that these guys don't really need too much absolute accuracy since they only have one analyzer and they're not calibrating signals, only measuring for relative values. If they're off by three DB and measure - 30 instead of - 27 it's not going to change the outcome of their review when the other phone they're comparing it to would also be 3 DB off at the same frequency.

Been to a big lab for some certification testing recently. They had all kinds of cool stuff in there from big turn tables to sensors powered over fiber optic. Most interesting difference between yours and theirs is they had the power and data cables come into the chamber under the turn table in the floor. As long as they are part of the system it appears it is not a problem.

The LTT team building such a state of the art, modern lab for testing feels like they're making a library of Alexandria of sorts, a place where tons of knowledge is gathered and the fact that they put it up on KZitem for everyone to watch feels like such a philantropic endeavour.

Your explanation confirmed quite a few of my theories, and illuminated a couple new ones that I hadn't considered.

@Macree I highly doubt they gifted the whole chamber for the cost of 30 seconds of sponsorship. In linus video where he talks about how much LMG makes he gives the average cost of a sponsorship. That chamber probably cost 50× the cost of a sponsorship. They probably gave him money off the cost but who knows. Maybe sponsoring a LTT video is now the same price as a superbowl commercial

That's actually pretty typical for engineers working on RF stuff. I work for a major semiconductor manufacturer and alot of our facilities have a room like that. It's essential if you're designing RF chips and want to get good measurements. Your typical tech KZitem channel won't have that, but rooms like that are more common than you might think, at least if you're in the tech industry.

@@pedro4205 There's more than you think, you've probably just never heard of most of them. We don't normally sell to consumers, we sell to other companies who put our chips in your products. So you'll probably never hear about Skyworks, Semtech, Navitas, Richtek, Nordic Semiconductor, Silicon Labs, Microchip, Renesas, and many others. Not all those are "major", but many of them will have an RF room for doing either RF testing or EMI validation. I myself work for Analog Devices, who is a major semiconductor manufacturer, but not exactly a household name (even though you almost certainly own products with our chips in them). Even back when I worked for Linear Technology (before the acquisition), several of our facilities had rooms like this and LTC was sort of a medium sized company.
