I remember hearing about a study on very simple electronic voting machines. These machines had a bunch of buttons representing the candidates. And in the study, they were able to make a decent guess of who voted what by looking at the rf emissions from the machine from a distance. I could imagine a whole computer being there could make the rf emissions less predictable. I can definitely think of some ways of making a simple machine like that more resistant against an attack like that. Idk if the study looked into that, I can't find the study anywhere.

Run a low power spark gap transmitter nearby to prevent snooping lol

Timing attacks and similar methods of vote snooping is definitely a big issue I've been thinking about for a very simple calculator like this. At first you'd think you could mitigate that with some sort of analog capacitor timer buffer thing somewhere in the chain but then you screw up a lot of predictablity needed to trust such a device...
