Nota bene that author asks that folks use the printables link so they can earn filament from the downloads. It's linked in that thingiverse entry but here's the direct link:

Does the software have an option for closing the session? Some burning software lets you leave the session open so that you can burn additional files to the disc later if it's not completely full yet, but many dedicated DVD players will only actually play the disc if the session is closed.

(This knowledge pulled from the dim recesses of my memory, which, like DVD, isn't what it used to be, so bear with me if I'm mistaken.)

Hey now, this isn't one of those trivial "do it on a computer" patents. This is a "do it on two computers" patent.

NVidia Shield K1 was pretty great too. It was also $200, about the same size (8"), 1920x1200 screen, fairly stock android, and had a pretty speedy chipset. It even had decent speakers. Came out 2014. I really liked that thing. I got it to replace my first Nexus 7 (2012), whose storage had decayed really fast, to the point it wasn't really usable anymore.

I've had pretty good results with photogrammetry, although the software I use is Meshroom, which isn't available for Mac. There are alternatives like Regard 3D and Agisoft Metashape, but I haven't tried them.

I do find it's pretty important to get a good surface for scanning, though. The technique that's worked best for me is to apply a thin layer of white tempera paint, and then flick on tiny spatters of blue tempera for texture. Tempera is nice because it washes off with water even after it's dried, and it has a nice matte quality that's useful for getting even lighting, which is important for the scan. If you've got an object where this is an unacceptable thing to apply to the surface, there are self-evaporating surface treatments you can get specifically for scanning, but they're crazy expensive, so I rely on tempera whenever I can get away with it.

I've looked at several of the scanners that are available, but for the price I'm not satisfied that they're enough better to make it worth it. Surface prep is still important, and the scanning software itself seems like a weak point for a lot of them. Meshroom is kinda slow, especially if you don't have an nvidia gpu, but it's free, which is hard to beat, and it's pretty surprisingly usable.

If you look on YouTube there are a bunch of folks who have made reviews of the Revopoint and Creality scanners. They seem alright, but not good enough to be worth hundreds of dollars to me.

There are two basic ways I can think of that you could still end up using OpenDNS without setting it as your DNS server in the private DNS settings. The first is simply if it's the default DNS that your ISP (in this case the phone company, since you mention you're not on WiFi) supplies. If you don't set a DNS server, then your system will obtain one at the same time it obtains an IP address via DHCP during the initial handshake with the ISP, because it needs to use something to translate website names into IP addresses. So if the ISP is configured to suggest OpenDNS, that'll still be what you'll use. You can override this by manually setting another DNS server. Note though that many DNS services (including a Google, if I recall correctly) use OpenDNS as a fallback setting, so if the main DNS site is down for some reason, you might still get OpenDNS results.

The other possibility is if have a VPN enabled, like Adguard or DNS66. These often affect DNS resolution as part of an effort to block ads. Again, manually setting a DNS, or disabling the VPN, should override this.

One last note is that there's a setting in Chrome that lets it bypass your DNS settings and use Google's own DNS for that app, so if you're using Chrome and Google's DNS server is down or doesn't have an entry for a particular site, that could still lead to OpenDNS being used for resolution. I haven't really found turning off that setting to work in getting Chrome to use my configured DNS, which is part of why I now use Firefox on Android, but in theory it should be possible to fix with "settings-privacy and security-secure DNS-use current provider," or with a custom configuration in the same setting, in Chrome, or by turning off secure DNS in the same spot.

Note that all these settings do have privacy implications, so it might be worth reading about those before mucking with any of them!

If you've got a 3d printer, an old phone is often a great octoprint host. It's got a built-in camera and everything.

Thanks for clarifying that! I didn't have to sign in again, but my account is on kbin.social, so I guess that's why.

Does this affect kbin.social? I know we federate with Lemmy, but I think there are also code differences.

If you're using Chrome, that's why. Chrome bypasses your DNS settings and uses Google's DNS because they found using the system settings was affecting their ad revenue. Using Firefox fixes this, although in Firefox you can just use ublock origin anyway, which works even better.
