hi again, since i had a bad idea in my last post i wanted to try again to get some feedback i could understand and apply.
the idea is to make a vacuum (the appliance) play a few seconds of r2d2 sounds. the vacuum is hauled around on the scaffolding on a construction site and wont be necessarily standing upright (while idle or in used).
my original idea was to have some kind of trigger through a sensor (SW-18010, or something) that draws zero power (like a tilt switch, but position independent). that trigger should pull a pin high on the dfmini mp3 player (cheap player board) which in turn would play a few audio files while powered.
so sensor -> 555 astable -> df mini player -> speaker (piezzo maybe).
any ideas or pointers? is the idea of zero power in this case even possible (never used the 555 before), is maybe a attiny a better idea while in deep sleep?
battery life of 1year + would be ideal.
