  1. Pure alcohol evaporates hard. So what's your plan for making a sealed enclosure that still has IO ports? But in general if no one has done something it's almost always for a reason. Probably no one wants to handle gallons of a volatile solvent when there's other stuff out there that is much safer.
  2. He still hasn't learned from Whole Room Watercooling: glycol isn't antimicrobial by itself. It relies on whatever you're cooling being 100C to be sterile so it's going to be screwed up shortly. You have a 3d printer and a CNC and that's your manifold situation with silicone holding it together? I'd have spaced everything out with a 1U gap and put drip trays with drain ports between each machine. And put a contact sensor on the drain so if water ends up in there you get an alarm.
  3. All thermal pastes are near-as-makes-no-difference the same performance. Sub zero you might need a different paste that won't freeze, direct die you can run liquid metal if you want to insulate the area around the die. Other than that, there's no difference between $1 generic and $10 Kryonaut.
  4. Didn't forget about ya, it just took a month to get the printed parts delivered. Looks like the dude use .1mm layer height cause it's finer than I've seen before. Anyhoo HOLY SHIT does the air guide work a treat. The videos make it much more obvious than the screenshots here but without the guide the stream breaks up within 18". With it, it's solid out to 3' easy. (the smoke is burning mineral oil, meant for this type of purpose) Video without the air guide: Video with the air guide: Turns out I also stumbled on the correct size of the funnel "vents" to not retrict the fan with the engine running. I measure about 11mph peak speed on the fan with no restriction, it drops to about 9.7mph with the engine off, and goes back to about 11mph again with the engine on indicating it's full flow. I don't have a great means of visually showing it, but I can feel the warmth of the exhaust on my hand much further behind the car so it's *throwing* it like I wanted.
  5. This was my question. "why is he trying to make 1U systems in the first place?" Fuck the rackmount, get some shelves and put a stack of narrow ATX cases on it. Oh look .... it's actually what "pros" do too: I see this a lot in my day job. They're so eager to dive into the "solution space" of cramming shit into a 1U case that they need an adult there to say "hey why are you having this problem in the first place? " He's not a datacenter where rackspace and floor space is revenue.
  6. Nothing about that sentence implies the lenses are permanently installed or can't be removed for resale. Kinda jumping to conclusions eh? I'm also doubtful that Zeiss is pre-making and "stocking" every prescription combination. It's literally tens of thousands of possibilities when you factor in astigmatism and the axis angles. They would do what every other eyeglass / lens lab does which is made-to-order. It's probably the Bloomberg guy misunderstanding the supply chain and *really* Apple just doesn't want to deal with separate lens orders and packaging and shit when they can deliver a prescription package in one shot.
  7. Yup. This isn't even a step in the right direction it's a waste of time. They won't even go offshore they'll just switch their AWS region for storage to Oregon or Texas and "oh look we don't have any data in CA anymore" Prop 65...for data.
  8. This was my $20 take on the headrest mount, since it only needs a saw and a quick welder zap (shaft collar is the keyword). If you've got a CNC you should have a welder...doesn't take much effort to learn either. This is also a repurposed VESA mount so it takes regular monitors up to 24".
  9. Sigh....it's like every year or so someone thinks they've discovered peltiers. The end of this story is just use a water chiller if you want slightly cooler water. It's not going to improve your overclocks by enough to make it worth the electricity cost.
  10. This is the one I'm currently using and seems to work fine plugged into a USB 3 hub: https://www.amazon.com/gp/product/B0B3JTLQ9S/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1 Basically every component is $160. USB, 3x monitors, $640 for the whole harness to run my desktop in the utility closet.
  11. The problem in the really small form factors is heat management more than anything. I use a thermaltake core g3 with a 3090 + 9900 (think it's discontinued now) as my PDXLan rig because it fits in a suitcase and I Can put a 27" monitor on top of it neatly, and even being larger than carryon size (it probably could fit in a carryon if I significantly reduced the padding around it) it's still really hard to extract heat off it. And that's with the whole thing watercooled where I just need to slam the beefiest fans possible on the front of the case. Have you considered something like the Core eGPU or similar TB3 enclosure with a laptop?
  12. Ya it was a weird dance combo of having a powered hub but not powering the receiver itself. And getting ground loop noise if I powered the receiver and the hub but the hub wouldn't work if it wasn't powered. And then I came to the conclusion there's probably only 1 chinese silicon chip that all these "brands" put in a plastic box. Similar deal with the USB hub chips where I had to go through like 5 of them before I found one that worked and figuring that even within the motherboard by itself there's like 3 layers of hubs baked in as it goes through the chipset through something else where it splits front panel and rear panel, through something else and then it ends up on the back of the motherboard.
  13. The video is talking about USB over ethernet, not USB over IP which is incredibly niche to where I can't think of any scenario a normal user would want that. VNC-like software probably dominates most every place it could be contemplated.
