That’s perhaps a testament to our dependence on modern machinery, if the skills did exist once.

- svachalek 5y agoIt's fairly simple to construct a way to see your own face. All you need is a high-grade color LCD or OLED display, a high-resolution digital camera, a power source, a few controls and a logic board. Too bad none of this was available before 2010, those poor ancients must have always wondered what they looked like.
- Joker_vD 5y agoYou 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.

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!
