Garden hose automation - suggestions?

[Jack Edin <nospam@xxxxxxxxxxxxxxxxxx>]

Hi guys!

Turns out I am one lazy bastard!

I am just too lazy to walk around and turn on the garden hose... then
come back later and turn it off...

Sheesh!

But my Elk M1 has a spare output I could employ to activate a valve, etc.

Home Depot has battery operated digital timers that screw onto an
outside faucet, then you attach the hose to it.

Not good enough. I've tried them before!

Anybody have a solution?

I would like to power it externally, as opposed to battery power
internally...

Perhaps a normally closed valve that requires, say 12 volts, to hold it
open...??

Keep in mind this isn't a sprinkler system, just a faucet on the side of
the house. With a hose hooked to it...

Thankx!

Jack
