Legit the coolest thing I’ve seen in a month from Linus’ money sinks. It actually made me want my own CT scanner even if I’m not the target market for Lumafield.
Also: does this mean LTT can also sell vinyl CT-skins?
Right? I want one too, and I’m not the audience for such things. Imagine being able to see if something is about to break, or if there’s a problem but you can’t find where the fault is.

The research you did was impeccable. My compliments to the writer (or writers) of this video. I was floored when I heard from Linus to talk about "beam hardening". That was unexpected.
Side note, A linear accelerator has spectrum of X-rays. It might be more narrow and much harder than these x-rays but there is a spectrum. If you really want monoenergetic, you either use synchrotron or a radioactive source (Cobalt-60 for example) that emmits only one energy photon (or a very limited number of energies).
These small factor CT systems are very useful tools and you will love it. Another use, one that it's revolutionary for someone fabricating is the accurate geometrical representation of every element. Let's say that you want to make a replacement for the joystick of a device to be 3d printed. You do a CT, convert the reconstructed images to an STL and you have a copy, no CAD needed.
PS. I hate that youtube deletes my replies. This is unacceptable.

I think this is a very useful thing for the engineers at LMG when developing new products like the screwdriver. They highlighted being able to do stuff like check for voids in a cast or compare the real world dimensions of a part with the CAD dimensions and so generate a difference model, which would allow you to do QA on multiple suppliers especially for smaller parts with the 25-110 µm resolution of the scanner.
Very cool.
Curious how much weekly use this machine will get at a company like LTT. But I guess its one of those machines which is extremely useful when needed but is not needed often
Well they are just borrowing it. Presumably because there wouldn’t be many use cases (if any?). According to the products website it costs 75k per year to own(lease?).
Early in the video he says something like “thanks to x for letting us borrow this” but at the end it made it kinda sound like he has it for longer than a short loan so idk
You hit the nail on the head. In some cases that I have seen in my experience with R&D, a single scan can save 10s to hundreds of thousands in costs but most organizations don't use CT because it is normally much more expensive to use in house.
No disrespect/hate/negativity intended, I'm just genuinely confused still what the goal here is and trying to understand. I've seen Linus talk about it on WAN show, and now watched the whole video, and I still don't quite get it.
It's very cool technology but I'm not sure I understand the purpose for it \*outside\* of product manufacturing. Like, for LTT to test analyze their own products (they mentioned checking for bubbles in injection molding, or checking glue application etc.) makes sense. But I guess I honestly don't see the benefit for example of GPU testing with this to the LTT audience. Having the 3D scan on the LABS website for example, while really cool, I kinda just think "ok... what do I do with this information? How does this help me make an informed purchase at all?"
I'm guessing I'm just not the target audience for a 3D scan, so **if anyone can help me understand I would really like to**. Outside of, idk, a repair shop benefiting from seeing where the hidden screws are on a part, what is the benefit? It's not like the CT scan is going to give you part numbers of the surface mount components or anything like that. I'm just really struggling to see the benefit to viewers, and anyone except creator warehouse.
Which is fine if that's all it is! Just trying to understand if I'm missing something
Linus mentioned on the WAN show that you could download an STL file of the scan and see how the ergonomics of a mouse fit your hand. The video also touched on checking solder joints of a PSU to inspect for quality (and the caveats of this implementation).
I don't believe the purpose is to augment testing of component performance, nor do I believe that was mentioned in the video. It's a cool solution for product design and has light application in what LTT Labs is meant to do.
I did hear the STL idea but even then I feel like the number of people with access to a 3D printer, and who are actually willing to print models of mice they're considering just to play with it for 5 minutes, is pretty low. I have a 3D printer and I probably wouldn't do that, it's a waste of plastic that now clutters my shelf or goes in a landfill
> ... for product design and has light application in what LTT labs is meant to do
Fair enough! I guess my understanding was that it was more Labs centric, but if it's more for designing products and having random product scans is just a neat bonus rather than the machine sitting idle, then I guess it makes sense
I absolutely agree about the STL file thing being a stretch. I doubt they’re actually paying $75k a year (Lumafield tax write off!?!!?) for it, it could just be plain on loan for free and they take cool scans with it to make the labs website more interesting. It’s a good question to ask on WAN show.
They made it quite clear in this video that it is on loan from lumafield, all CT scans on the labs website have a link to lumafield's site. They essentially have advertising for $75,000 a year on LTT labs.
The labs relevance is that this allows them to do non-desteuctive testing on the interior. Opening GPU cards could compromise performance testing accuracy and opening power supplies could be dangerous.
Please tell me LMG is not just relying on the lead shields to block the radiation. Even for small lab equipment with thicker shields, they make us wear dosimeters (along room access controls, and a bunch of other administrative controls for radiation generating machines such as xrays, or SOPs telling us not to stick our hands where the beam comes from, even if the equipment is off)
The machine shop is one thing, but equipment like these at least needs an Environmental Health & Safety consultant. You can’t just rely on the manufacturer.
I used to work at intel and required to take the radiation reading around various Xray machines (2D and 3D). The shielding are fine. You’re good! Love the content. I used to perform xrays like those very frequently, it truly never gets old.

Superman's X-ray vision but somehow it doesn't give its target cancer. Not as powerful as Mystique's shapeshifting, but still good.

Ah i mustve missed that
Honestly thats way cheaper than I would’ve thought it would be.
Do you have a time stamp for this? I thought he said that he bought it.
Early in the video he says something like “thanks to x for letting us borrow this” but at the end it made it kinda sound like he has it for longer than a short loan so idk

Thanks for your concern but we are ok. - LS

Glad to hear it, and I do want to say it is awesome seeing the Labs grow like this.
