A flip-flop would work to convert the analog to 1-bit digital, but you could also tweak the magnetics and with a better ADC get velocity measurements! Add some software and you can type ANGRY MESSAGES by just pounding on your keyboard, no shift/cruise control needed!

Realforce did this a few years ago with Topre switches (which are capacitive). Here's a video demonstration of someone using a keyboard like that as a piano [1].

Cute idea but I’m not sure of that. The sensing method is by multiplexed polling.

that's a cool idea!
