That Veritasium Video is the reason I now use QR codes with UUIDs inlaid into my art and other projects as a digital signature. I know when something I share has been tampered with because the whole thing is itself, a QR code.
I'd suggest you use a special hash algorithm. QR code is supposed to survive a big lot of tampering. If you want to detect any tampering a hash of you picture would be a great solution. You could use a small convolutional network like ResNet if you'd like to ignore compression algorithms tampering with your picture)
Also, if you're worried about AI using it as training data, Nvidia and others made tools to poison art and make it absolutely destroy the training data
19:25: This is due to tile tick priorities. A repeater facing into another repeater will always be ticked before a repeater facing into redstone.

I did not expect the first time finite (Galois) fields to become relevant again in my life to be in QR codes lol. I remember learning about them while taking abstract algebra but we mainly studied them because they’re interesting and we only vaguely got references to them being used in cryptography
Btw if anyone is curious what they are, here’s the wikipedia article (GF(256) is the finite field of order 2^8) en.wikipedia.org/wiki/Finite_field?wprov=sfti1
except in a sudoku you know witch numbers are missing, the cool thing about error correction is that you have no ideea witch numbers are missing, you just get a filled up sudoku table with wrong numbers and you have to guess the original table, you cant just resolve it any way you want
@@FractalINDthat's true about sudoku as well, a proper sudoku table has one unique solution and you do NOT know what they are, you are filling in the unknowns using properties you know to be true, thus the same principle applies and the anology is true. Also it's spelled which not witch, tho that's not rly important
omg i knew it bro this is a gigantic coincidence, 1st a guy from synergy of all places made a qr code maker, 2nd the veritasium vid, 3rd this! what is happening
You are a madman, and I mean that in the best way possible! It's insanely impressive that you managed to pull this off! Can't wait to see what you come up with next!!
I saw that same qr code video like a month or 2 ago. Its crazy how interesting they are compared to how boring they sound. Perfect example of don't judge a book by its cover.
this was a very interesting project! i highly enjoyed watching this video, you explained the concepts behind the qr code generation really well and it made me appreciate your redstone in a new way as i was able to understand which parts do what and why. i'm going to send this video to my friends :D
19:25 Explanation! So when there is a repeater (facing the same direction or to the side or a comparator facing the the same direction or to the side) in front of normal repeater it has a priority over a normal repeater while torches have less priority than both of them and I also have to say that if the repeater gets depowered and repowered before it depowers it never depowers. What exactly happens is that when the torch turns off 2 ticks later repeater turns off first and then torch turns on (because repeater has priority) then 2 more ticks later next repeater doesn’t turn off because the one before it has priority (because it has a repeater in front of it) More info there: m.th-cam.com/video/03eaDmffj5Q/w-d-xo.html
maybe the problem at 19:25 is schedule list. If not, then it is an interesting thing to discover. TL;DR: lv 1 + lv 2 repeater is different than Lv2 + Lv 1 repeater. Someone named cubicmetre has a video (the wonderful world of wireless redstone) about how to use it for wireless redstone at any distance apart (as long as the chunks are loaded of course).

19:28 This is, because there's a."hidden" mechanic in minecraft, which decides, which way the redstone or signal (I'm not sure which one) travels in which direction first. So, if you mirror a Redstone build, it could happen, that it doesn't work correctly. It has also something to do with the alignment, where the signal/redstone has to travel. Sry, I'm not really good at redstone (I need 3 hours to get a basic door working 😂😂😂), but I saw this in a video of phoenix or so, where he explained it. I remembered the important part, but the rear is lost in the void for me, sry 😂😂😂

Thanks for the shout-out matt! It was a lot of fun working with you on this project and helping along the way.
Pretty cool dude
Wait, HOW DO YOU TYPE THIS?
@@Creeper_Pro_ what?
@@kai-EqF It says 5 hours ago, and the video was released 30 mins ago

Rickroll?
It got me ):
You MEMORIZED the rickroll url?
I only remember the w4w9W
Cuz it's like www with a 49 as the spaces.

Ah of course, it’s all so obvious now
0:37 I recognize that URL anywhere
even pixelated it still scares me
Only one on yt that ends on xcq
Rick rolled
@@Papasot ru sure? i feelt like there's gotta be more
@ I’ve never seen any other video that has a url ending on xcq. There are definitely more videos than rickroll.
The part at the end, when he blows up the QR code and it still worked actually left me in awe. Outstanding video Matt!

3:12 I'm pretty sure that's a rickroll link as I recognize the dQw4w lmao
HOW DO YOU RECOGNIZE A TH-cam URL?!

Ah, he didn't hack Linus using only redstone
I love this!! It's like the perfect sequel to Veritasium's video!
Heartbreaking: computational redstoner discovers tile tick priority
the next challenge is now
*READ THE QR CODE*
21:52 Thank you so much for that, I was having a bad day. Those were the words I needed.
As someone who knew about Hamming codes, seeing the Reed-Solomon algorithm is fascinating.
Choosing version 3 and error correction L was a wise choice.
16:11 Amongus in the QR Code
If you're still confused on how Error Correction works, think of it like a sudoku. You can still solve the sudoku, even if most of it is missing.
;)
cool!
except in a sudoku you know witch numbers are missing, the cool thing about error correction is that you have no ideea witch numbers are missing, you just get a filled up sudoku table with wrong numbers and you have to guess the original table, you cant just resolve it any way you want
idk how this relates to the explanation(which i understood) but okay if u think so
@@FractalIND yup exactly

I’m always amazed by what you build, thanks for making content❤
ok, what about a qr code reader? (in redstone)
just watch the video in reverse
omg i knew it bro this is a gigantic coincidence, 1st a guy from synergy of all places made a qr code maker, 2nd the veritasium vid, 3rd this! what is happening
16:11 when the QR code is sus.
loved the silent humor here and there throughout the vid :-D

Amazing video! When is the next episode of minecraft cpu though ?
3:19 You should look what a Data Matrix is. I think it’s like a QR-Code but without the error correction.
I think bro did an even better job than veritasium explaining the operations. Epic build!
I tested every QR Code you showed. no damn rick roll
The best prank on people is making them be in a constant state of fear
@teknoshadowwashere right
i love this, i love it when the projects are "useful", im aware all projects are useful. yah know what i mean

omg cool idea to make qr code generator with redstone i never seen this
Polenomial divsion itself does not sound that difficult but making in redstone is on a another level
0:12 from the thumbnail, I knew this has something to do with Veritasium's QR video
this guy! insane! you are a real legend keep it up!
I can’t even do this in python, truly magician
making a game engine in minecraft next?

i thought 4:55 is gonna be rick roll
I didn't expect that 7:20 even it was so obvious. I don't believe how much a laughed at that shit

The fact that you made the display only 43 characters long triggers me so much
ngl kinda hype. i have been curious about how QR codes kinda work for a long time so it is super neat to see it explained in minecraft
I don't even play minecraft anymore like when I did as a kid. Now I just watch your videos and do this crazy stuff
Now add a display to your redstone computer and program in in assembly
Veritasium!
Now make a V40 one
just kidding this is crazy impressive!!!
Don't forget the recently added rectangular QR Codes.
I heard you say QR code generator in minecraft and dropped my jaw lmao
1:20 but the maker made qr codes open acces to everyone
It would be fun, if you made this render as a map.
Great
I made a qr code display recently showing 20 of my fav ones not custom ones
This is awesome!
i would say thank you for helping people
16:12 among us spotted on the left side of the qr-code🔥
Dude great respect for doing all this in a kids game I would have never got this right
LETS GOOO
great vid
Watching this as a break from studying for my computer architectures exam is ironic.
suddenly i want to see someone implement the USB protocol in redstone
This guys doen't make minecraft in minecraft, no no no, he makes real life in minecraft
3:12 I can't believe I've been rickrolled like that
bro explains better than my math teacher
Cool!
Now someone just needs to add a rickroll qr
Vertuisum reference, (he did the same thing)
Before yall say anything i just opened the video
16:11 ඞ
Damn, I didn't watch the vid yet but damn, he had to do red-salomon in redstone
My guy... at what point do we need to acknowledge the fact that you're probably a threat to national security with skills like this?
everyone know its a good day when mattatwings makes a new video
matt>crafty
This is epic!
The QR code at 3:55 takes you to a video that is not appropriate for the viewers of this channel.
This was an interesting experiment
Would it have been possible to program this with the redstone computer you previously built?
Matt have a beef with Crafty with those QR codes 2:06 💀💀💀
Awesome, more plz, like Redstone pc made with create mod.
do you have a redstone texture pack for bedrock i cant Offord java so i have to play on bedrock
2:03 whyuscan?
2:06 subtomattbatwings
mattbetterthancrafty
(i couldn't scan v40 qr code)
16:11 how did a Impostor get there?😅
Time to break my brain and do a break down of the build, just to answer one question can I transfer this to bedrock.
we already have doom now idk what else to comment chat...
Next:
I made chat gpt with redstone
YAY
