Can a 12v windshield wiper pump be run from a wall wart? I am putting
together a mist system for a terrarium, so it will run about 1 minute
2-3 times a day or so. If it will run from a wall wart any suggestions
would be great.

Wall warts ONLY handle currents up to about 1 Amp - MAX.

Um, not to give the op hope, but ...
See cat# dctx 1215 from http://www.allelectronics.com/
for a 1.5 amp 12 volt wall wart and cat # 16760 from
http://www.mpja.com/ for a 2 amp 12 volt wall wart.


Yes, these are OLD surplus designs -- new mfg. are generally now avoiding
(that is why they are on the surplus web sites/resellers).
They usually do not stay in the duplex outlet without screw attachment to
cover plate.
Readily available 1 and 2 foot line cord jumpers --- help with this problem.
These older designs stretched the definition of WallWart -- due to
transformer's weight !

New ones are more "brick like" with short AC cord OR use standardized IEC
jack.


Back to the original problem. If you want to pump mist into a terrarium,
how about a perfume atomizer driven by an aquarium air pump? Or, for
real tech overkill, an ultrasonic nebulizer?
