This enlightened forum already discussed pot watchers (link), but since the cruel world out there is science based the eyeballs will not work except for cauldrons with magic potions. Therefore I suggest the science based bubble watcher. It consists of a microphone, signal processor, and buzzer. The device is packaged so it easily hooks onto the rim of any pot or hangs on the lid with a suction cup.
The signal processor analyzes the sound from the pot. When it hears popping bubbles at a preset frequency the buzzer goes off to warn the cook of an upcoming spill. If you are lucky enough to have a Bluetooth enable stove the device can adjust the heat by its own.-- kbecker, Aug 11 2003 (???) Pot Watchers http://www.halfbake...idea/Pot_20Watchers [kbecker, Oct 04 2004, last modified Oct 05 2004] I was going to say - why not a thermometer or pressure gauge? But then it wouldn't be the same, would it.-- Detly, Aug 11 2003 [det] A thermometer doesn't work because of changes in atmospheric pressure, tried it, made a mess. A pressure gauge works, but you need a closed pot....and yes I was looking for widget that could sell Brookstones if someone would build it.-- kbecker, Aug 11 2003 Will there be an aftermarket urinal-mounting kit for this?-- DeathNinja, Aug 11 2003 I meant some sort of pressure gauge submerged in the liquid, but I know little about pressure gauges. Still, it would be kinda fun to clip on your own little "Bubble Watcher."
[DN] : What?-- Detly, Aug 11 2003 [DN] I know, the words "bubble" and "bladder" sound kind of alike, but still the category (kitchen appliances) should have given you a hint that we don't do urinals here.
However, I have been thinking for a while now about a "Direct waste water recycling" appliance. Once it has wound its way through my head and guts I'll post it here so you can ask this question again.-- kbecker, Aug 11 2003 I'll take that as a "no" then ;)-- DeathNinja, Aug 11 2003 Yes ;)-- kbecker, Aug 12 2003 Why not a thermometer, and a pressure gauge for the AIR, and then a computer to calculate the right temp? Should be easy enough.-- zigness, Feb 16 2004 random, halfbakery
