So i collect playing cards and today I got two new decks, one was the theory11 deck by neil patrick harris (link for reference) and one of the special cards at the back was this:

(if the picture breaks, its a black card that says "This is going to be a challenge. Just as a spider spins it's web, I've taken a page out of Cardano's book and created a puzzle. Look upon photos and images inside this deck. You can do this - just look closely at the cards. Good Luck! -NPH)
I looked it up and this has been around for at least four years but nowhere online has answers to the passwords, hints sure, but no real answers.
I followed the clues (going to nph.cards and completing everything on there i can) but now I'm stuck on the fifth puzzle, the Cassette. It looks like this, the russian translates to "Happy Birthday" and all the buttons work. Someone hinted to reverse the audio but i have minor auditory processing issues so even though I reversed it, it's still not clear enough to make sense to me. Since it says Happy Birthday, nph, and its a deck by nph, I tried to enter his birthday (and...a whole bunch of other dates) as a password but it didn't work.
I don't want to give out the answers since it's fun to solve them yourself, but if anyone does want to help figure it out, pm me and I'll send you a picture of the card needed to actually get to the puzzles and a list of the hints or answers i do know. (or if you have solved it and are willing to give hints p l e a s e pm me i've been staring at this cassette for hours lol)
