Amazing. I literally did this and then decided it was overkill. Almost with the same hardware!

Lol that's awesome

EDIT - I had an idea that I'm currently working through that I like but am a little stuck so taking a break before I revisit. TLDR is to use an ATTINY85 to auto-"type" the password in for folks who bring a laptop and can't scan the QR code. I wrote the Python code to generate the .ino script that would actually do the writing, but I'm having a little bit of trouble getting micronucleus to write the script to the ATTINY without an un/re plug. You can see the WIP on my digispark branch in that repo

Wouldn’t it be easier/maybe more practical to print the password to the e-ink screen as well?

(QR code error correction is usually enough to let you just knock out part of it and put the text right there.)

Maybe! The problem I was trying to solve was that a 30 character password randomly generated is a pain to type out by hand haha. That said I think having the text would be a step in the right direction

Bootstrap it with a shorter password:

1. Have the display show a 5-digit PIN (TOTP or something that changes every minute or few)

2. Let anyone connect to your network, if they go to a browser window it will show the capture portal

3. Enter the 5-digit PIN and press "enter" and the page will show the 30-digit password so the user can copy+paste

4. User pastes password into WiFi screen and logs in

Make sure to rate-limit this endpoint to prevent random PIN attacks.

Yeah that's certainly another solution. I haven't played around much with the captive portal capabilities of my networking gear but maybe I should

Just use diceware; 3-4 randomly selected words is enough entropy but still easy to type.

It took me a second to understand what this does, but wow what a neat project!

Thanks for sharing, this sort of overkill is my favorite kind~ Cheers @koins!

Lol thanks! I strive to bring more nerd-value than real-value :P
