You jest, but I've heard a tale from a local engineering college: they regularly give to the graduating-year students a task to design some system which, after you remove all the fancy wordings, is basically insides of a toilet cistern/tank. Year after year, the students keep producing astonishingly convoluted designs.
- jazzyjackson 5y agoI once re-invented the whistling teapot while deeply engrossed in using Arduino for anything and everything. I had only saucepans to boil water with and wished they could alert me once the water reached temp, perhaps optically sensing the turbulance of the surface. My roommate could not roll their eyes enough.
- Joker_vD 5y agoWell, if you put a lid on a saucepan (and you should, it conserves energy and makes water boil faster) you can detect it clattering when the water starts to boil! So you don't need any optical input, a microphone will suffice ― which is cheaper, too. Filter out the low frequencies of water humming, amplify the rest, and you got a (not-so-nice-sounding, because it rattles, not whistles) boiling point alarm!
