Audible alarm for blind person [RE-wrenches]

[Bob-O Schultze, Electron Connection]

Frank,
Tons of options for this. A Link 10 Choice (or an old E-meter with 
the LLO option) would be best because you could do the alarm based on 
A/hrs, not volts.
Failing that, if she's got an SW, use one of the voltage controlled 
relays. An old Trace C-30, a simple switch (anyone making them these 
days?) Whatever you use to trigger it, a piezo alarm is LOUD, 
obnoxious, very low wattage, and cheap. Hosfelt Electronics, All 
Electronics, Jameco, even (dare I say it?) Radio Shack! all carry 
those.
Good Luck, Bob-O
