Safe shutdown on unplug

[eliddell]

So I know how to create a switch to turn off a pi safely, but with this mirror and the tendencies of my fiance to just unplug things, I was thinking of using something like that adafruit power boost 500 to basically have a small lipo battery supply that charges when plugged in to the wall, but then sends a power down command when unplugged while supplying power via the lipo. Problem is the powerboost isn’t really designed for that… it can be used to send a soft shutdown when the battery but is low, but I really want it to shutdown when not charging.

Has anyone else implemented something like this… really just looking for a good hardware solution.
