Yesterday I started building out some qrcode tooling for myself starting with qrcode.waylonwalker.com. This is part of my tinyapps project.
Also dug into qr codes in python to try to get some easy and small qrcodes that I could add to my blog posts for others who find a post on desktop and want to open on mobile.
This is what I am going for with qrcodes on my blog posts.
