> I'm so glad that smoke detectors have built-in batteries that last 10 years now, no more checking your batteries or looking for a 9V somewhere when it starts beeping.
My local code requires these in all residences, actually.
I'm not opposed to them, but I, uh, may be violating that ordinance in one location so I can get a better alarm. That takes an AA though, so no weird 9V thing.
(The motivation is as follows. Wait, I mean the motivation would be if I were to be violating the ordinance, yes that's it. Anyway, there are two kinds of smoke detectors -- ionization and photoelectric sensors. Each has strengths in terms of what kinds of fires it can detect better than the other; ionization detectors do better when you have a fast burning fire, while photoelectric does better when it sits there smoldering for a while. Both kinds of fires are realistic threats in a home. But you don't have to pick one or the other -- there are dual-sensor alarms that have both. However, you can't, or at least couldn't when I was outfitting my house, get these with a lifetime battery -- only with a normal, replaceable battery, or hard-wired with battery backup. But I'm also somewhat okay about testing them.)
Nothing yet, haven't completed the build, but I got 2 flame-activated stove-hood extinguisher cans. It will make a right mess of the printer if it ever triggers, but they were cheap and are effective. I am also going to build an ardino electronic flame detector, hack on a $20 smoke alarm and have both the ardino and octopi capable of killing the power to the printer via a 110v relay board if they receive an adverse sensory input.
