Where can hobbyists purchase hackable/programmable internet buttons such as this for a reasonable price? I've seen a few around the place but the costs are exorbitant for what they are, and hacking the Amazon buttons is too much effort (and they're hard to get outside the US)

Is the $15 AWS IoT Button[1] too expensive?

For a fun side project probably not, no. Anything past that (even a small scale beta) and yes $15 is quite expensive for what you are getting.

As said, doesn't ship outside US

esp32 + button + lipo ~= [9,15]

Nice thing is you could easily have multiple buttons and lights for feedback.

That's the route I'm going down, but for someone not so skilled in electric engineering, there's a bit of work getting the battery working and wiring up the switch, then making a suitable case. I'd like to just focus on the programming side of things, and am a little surprised there isn't an off the shelf solution.
