I don't like watering things by hand, so one of the first things done when 
we bought this house was to run a lot of irrigation pipe...  The control 
system is currently based on an old USB-connected GPIO device thingy, but 
I've been considering using the nearby arduino (currently used for flow 
monitoring) instead.

It's kind of embarassing, that whole spaghetti-pile up there.  OTOH, it's 
in place, and has worked for many years....  must... not... needlessly....

Meh.  Buy one, play.  Not an expensive toy, really :-)  And there's *lots* 
of easy-to-follow tutorials out there.
