No.3797

Anylain know of free QR code generator websites that allow QR customization like the one I made shown in the picture? I made this one with a non-free site that has a temporary redirect before taking you to https://lainchan.org but I'd like a 100% free QR gen that I can make lainQR's and print them off and leave random places.

if you do a search on github there are a ton of qr generators that you could probably edit a bit to get what you want. Or maybe just do a bit of digging and find one that suits your need. Basically all you'd need to do is be able to select the color for your squares and make the background transparent so you could put an image under the code.

Kind of surprised that this works so well.

Here you go: http://cgv.cs.nthu.edu.tw/Projects/Recreational_Graphics/Halftone_QRCodes/

You can even import gifs into them and they'll still be able to scan.

yeah that's pretty beautiful. How much would it cost you to remove that redirect or is that just not possible?

Not OP but i experimented with GIMP.
I think if i made the "eyes" on the corners more distinguishable i might need less contrast in the middle.

Also in theory QR code should also work light on dark but it doesn't always work in practice.

That site is pretty neat, even though it only lets you export so low resolution images.
I played a little bit with that and photoshop, but it's really hard to get something scanable and still good looking. Right now I hit neither.

Actually these don't work at all, I think they atleast worked on the website, but not even with a neutral gray. Probably should try a different design, maybe back to the stars. It's really interestingly done in op, maybe I should just try to recreate that.

I can go 300x300 if I don't crop the QR I have. I didn't save the gimp project so I'll have to re-make the custom one. I like making these large enough for sticker sizes so I can sticker bomb things.

512x512 will work for a 3" ish sticker. Maybe Kalyx will take your design and print them on stickermule.

I'll generate a QR around that size and see what I can make out of it. I want to make a ton of LainQR and sticker bomb my city in the alley ways and parking garages.

Hey I really like that one, and it validates perfectly! I'm working on another right now. I like the design idea with lain backgrounds but I'm going to try something different with this one that may look cool once it's stuck on a wall somewhere.

I made these two, I like how the image comes through the QR itself instead of being transparent through the background. Both validate.

it'd be a cool project to make a lot of these and make like a lainchan quilt of qr codes that lead to schway soykaf

acid tab sheet style

  No.4458

What other services do you think would be good to provide through subtle placements of QR codes in the wild? I'm considering turning a Pi-sized board into a server where I can host files and users can leave a message for me to put something up. It'd be a comfier piratebox, basically. Strategically placing QR codes that scan to its domain name would be a clever way of restricting access. Maybe change the name + IP every month and print a new set of QRs so people have to keep hunting and word of mouth could spread but not for too long.

Here's the code by the way. I just the generated overlay with underlay.png in gimp, no layer mask.

this picture I've had the most success with, in the sense that I don't have to fiddle with the focus as much and it will scan from a bit further away (maybe 2 feet from the screen)
