Hello all.
I'm hoping you'll find this backstory somewhat amusing, and I'm including it for the purpose of its entertainment quality and to see if anyone has any better ideas.
For context, please view this http://3.bp.blogspot.com/-ZHweCp1Yfr8/Tn-CTr0P6_I/AAAAAAAAB80/bixPQ7-yarM/s1600/nytt+bad21.jpg
Anyone having cats will understand the obvious attraction this marvel has to felines. Now I have two cats interested in it. Cat one will balance at the edge of the sink, yelling loudly to DEMAND having the water flow, cat two... not so much. Cat two will happily turn on the sink with her paw, and she doesn't really care about the amount of flow or temperature...
Besides the obvious waste, it could be dangerous with the hot water.
Closing the door to the bathroom isn't an option as the cats will claw at the door, it's a very popular spot because of the underfloor heating.
Using a rubber band or some other sort of obstruction works, but we forget to put it back on after using the sink and she'll chew through duct tape when we're on holiday. (It's like a time pencil: you can see how far she is from getting through)
I want to do solve this by using some water valve solenoids, a li-ion battery, switching regulator and some sort of timed button.
I want to be able to press a button, which turns on the NC solenoids for say 5 minutes. I'm having trouble finding the timed button. I also want it to be as power efficient as possible.
