Not so long ago I bought my first 3D printer. It hasn’t shipped yet, but I’m gathering knowledge so hopefully I’ll be able to use it when it arrives....
I was playing with my POP2 3D scanner, scanned this toy fish of my kid’s and 3D printed the resulting scan. I had to manually draw the spots on it, but really happy with how it turned out. Pictures don’t do it justice just how exactly the same they are in hand. Not all of the textures came through though.
Well, this is with a RevoPoint Pop2. This is 2 or 3 scans merged into 1, no editing outside of the scanning software. I’ve been extremely impressed at how well this can scan and produce a 3D printable STL. The only thing I haven’t figured out is how to get a file with the surfaces usable in CAD software. I can pull the STL in and see it, but not constrain it or create intersections with it.
For scanning, Epic Games has a phone app that I’ve seen seriously impressive results from just photogrammetry. I did not have very good luck with it, but it is definitely capable of great results. If you have a newer iphone, some of them have a depth sensor and apps available that can 3D scan.
If you want to scan primarily 3-8" objects the Pop2 is great. It’s even at what are probably clearance prices at Amazon right now ($400-450 USD). I bought mine used/open box directly from Revopoint via ebay for $400. Definitely get the turntable. It is definitely worth the extra $50.
your reference. Solidworks does have a point cloud tool but no idea how good it is. Working with surfaces in Solidworks usually is not hugely fun.
All I really need is to get the surface data into something other than a “mesh” format. My actual job is working with Catia V5, but my work does not have any of the applicable Catia licenses to directly work with mesh files (such as STLs). If I can get to that point I’m golden. I have plenty of experience working with and creating surfaces.
FreeCad can apparently make a step file from meshes with a few steps, but when I did that with a simple 1 2 3 block scan, the result was about 2.5GB’s, and tends to lock up anything that tries to open it. I may look into an open source program to create usable surfaces from point clouds instead of trying to use meshes.
I really love the way Kde 2 and 3 looked back in the day. I love KDE Plasma, but KDE 3’s design just hits differently. Maybe I should try one of the KDE3 forks again for nostalgia’s sake. I think one of them added start menu search, which was the main pain point last time I tried one. Now to figure out how to install Trinity.
Wow this sounds a lot like my outlook with Ff7 remake. I begrudgingly bought it on steam when it was on “sale” for the still too high price of $40, and when it was good it was great, but other than one mission it is just the story of Final Fantasy VII up through Midgar with a stupid amount of boring fetch quests to pad the time. Saying it is maybe 33% fun engaging game/story 67% boring fetch missions or “go kill this boring monster” over there is in my opinion being very charitable.
It is my opinion that it should be legal to paint said stripes on someone’s car if they park over the line. Should really hammer just how much of an asshole someone is if they have multitudes of stripes.
I just recently got a Revopoint Pop 2, and I’ve been thoroughly impressed by it. I feel anyone looking at 3D scanners needs to keep expectations in check (they are not magic), and it takes work to get good scans, but personally I think it’s well worth looking at Revoscan. For hand size and up, the Pop 2 or Pop 3 are great size. The mini is for very small objects, and I’m not sure of the Range can do that small (but it looks SIGNIFICANTLY better for larger objects). I’ve only had it for a week, but do you have any questions on it?
Also, check their ebay store. I got the Pop 2 openbox that way directly from Revopoint, and it was only $350 for the base, or $400 for the complete kit with turntable, battery bank, and case. The turntable alone is DEFINITELY worth the extra $50.
Sorry, it’s revopoint not revoscan. It’s easy to say the wrong one when all you see if the software day to day… I fixed my comment above. I’ll try to get some screenshots up later today, but I’ve scanned lots of things with the turntable and I scanned my 21 month old when he was asleep on his beanbag.
Have you tried the reality scan app by Epic games? I did not get great results from the one scan I tried, but I’ve seen really good scans, and it doesn’t care how fast you go or what direction.
That being said, as long as the revopoint keeps tracking: no errors. The only times I’ve had it lose tracking were when scanning a 1 2 3 block without spray (shiny metal) and when trying to scan my car dash in a fairly dark garage (high gloss black). For anything shiny and maybe very dark, you need spray of some sort; either the purpose made stuff or talc free foot spray.
The meshes can vary from mostly smooth with some bumps to kind of having a fish scale effect, but the later is from over scanning. Apparently you should always scan either one rotation on the table or only roughly 300 frames at a time for the cleanest result. You can convince as many scans as you want though. As I said below I’ll screenshots of my results later tonight.
For 6" objects the POP line is perfect. For people or people sized objects the Range looks significantly better, but the range might struggle with 6" objects. I guess it’s pretty common for people who get into 3d scanning to have multiple scanners based on what size you are scanning. The POP 2 can scan people, but you have to move a maybe 5x5 or 6x6 “window” around them to get all the detail. The Range had a significant larger view/window to scan people much much faster. The faster you can scan the less likely it is to lose tracking.``
Here are some screenshots of scans. The head is my scan of the included sample part, and the 1 2 3 block is a machinist tool that is exactly 1 x 2 x 3 inches. I 3D printed it, and with calipers it checked about .010" off per 1", or roughly 1% “small”. That is with zero CAD work or scaling.
Quick T Rex toy scan (~4-5" long); the black claws didn’t show up. scanned on the side they did, but they didn’t merge well. Coelacanth figure again ~5" long. The texture of individual scans on this guy looks amazing, but falls apart when merged together. The mesh itself looked quite decent with the merge though. Both of these could be 3D printed as is.
My honest advice is don’t worry about the old lenses. Any camera should come with a comparable lens to the 18-55, and the 55-200 is not anything to base camera choice on. The only compact cameras that can properly use those lenses will be Canon’s discontinued EOS M series. It is a totally dead end system which has ceased development. I don’t think your lenses would work on the crop bodies of their new system, but the difference in price would make it a bad choice anyways. You can technically get an adapter to use the lenses on Sony’s cameras, but they will not work quite right in my opinion, will probably work much slower, have focus issues, and maybe even have issues with the stabilization causing blur.
That being said, I really think the Sony cameras would be the way to go, but look at the used market. At least in the US, Sony made so many cameras that the used older models go for a lot less money, so they are really cheap to pick up. The A5100 would be a great balance of small, good image quality (24MP), and I assume very cheap. The A6000 line would add an eye piece but be larger. The A5000 would be good but lower resolution (20MP), and the entire Nex line are older yet and mostly cap at 16MP. The 16-50 lens is super tiny when off, and in my opinion a very under rated lens.
I understand setting your DNS to cloudfare helps staying anonymous out there. So if someone sets a Pi Hole linked to Cloudfare does it cover one’s tracks? Together with a VPN.
With that being said, as others have said, a DNS is like a phone book. By using PiHole with it going to a privacy respecting DNS service, you in theory eliminate being tracked by a DNS provider, but you do nothing to prevent your isp from tracking which ip addresses you access, and you do nothing to prevent search engines tracking which results you click on, you do nothing to prevent your web browser from tracking your browsing (especially on Chrome and Edge).
In summary:
DNS lookups: yes
ISP with IP addresses: no you would need a GOOD VPN or TOR and either one properly configured
Web browser: no, you need at least Firefox with data collection turned off, preferably with something like ublock installed.
Search engine: no, requires more research but supposedly duckduckgo and eccosia are privacy respecting *citation required
I thought a hacked 3DS couldn’t play original NDS games without one of those ROM cards for the original DS. Can you run original DS games without it now?
It's possible, but I don't know for sure. I refuse to run Chrome because we don't need another browser monopoly to stifle innovation.
The Internet Explorer era was terrible, and we STILL have broken things that only support a now dead browser. So many things went all in on proprietary Microsoft standards for Internet Explorer, and now you cannot use them. Most older camera DVRs and stand alone ip cameras fall into that category.
Another example: I can't say which company, but a very large company you've almost definitely heard of, required that all of their vendors buy all raw material from their subsidiary, but you had to use a site that not only was Internet Explorer only, but an extremely out of date Internet Explorer only. basically you had to have an xp machine up to a couple years after xp was no longer supported, to order several thousands of dollars of raw material.
All it would take for this to happen again is for Google to release a new API or "feature" that legally or technically a browser like Firefox cannot implement. Then if they decide they don't like that standard or Google actually miraculously gets broken up for being a monopoly/anti competitive everything that uses it will again no longer be usable.
