@selmins @smallcircles what are those things on the back of the big phone lens and what is the person doing with it
@v0idness @selmins @smallcircles
It's a rotary dial, which is the tool that old land line phones used to enter numbers to initiate phone calls before touch tone keypads were adopted

@lilbatscholar @selmins @smallcircles ok so its like outdated ancient technology, nice
@v0idness @selmins @smallcircles yeah, it's like the phones get more and more "advanced" and built out and suddenly we're back at the really old phones
@lilbatscholar @selmins @smallcircles idk man i just use an old ass android phone from like 5 years ago

Funny thing with that is, the disc thing was just riding off a sequence of metal contacts introducing signal interruptions on the line just like the one when you'd hang up the phone by putting the receiver on the hook. Well if you knew that, you could still dial out by clicking that hook manually multiple times fast, corresponding to each number you wanted to dial in, so you could get around any parental lock your parents might put on to hold the disc in place while they were away from home. 😈
