Back in 2014 the irrigation setup in my house needed some serious work. I had to change the location of one of the valves, and all of the wires between controller and all of the valves were ruined and had to be changed.
I started looking for a way to connect the valves I had to the controller I had, BUT without running any wires. After all, it was 2014 and everything has gone wireless "allegedly" and naturally someone or some company had done it. It has to be on the shelf somewhere, right?
After more than 2 or 3 trips to local hardware stores and various distributors and a handful of phone calls to different companies I found out there is no such thing. I did get few laughs and some strange looks in the stores when I asked for a wireless retrofit gizmo. But I could not find anything that would do the job.
So, natural thing was to post the question online which of course brought out all the smart A... ligators and definitely got some good laughs.
Few told me to change everything to DC-latched valves (hockey pucks) and be done with it, and some told me to just rewire the system and forget the whole thing. To make the story short, I got a bunch of advice and some hot air here and there, but it was all good. Couple folks told me "if" there was such a thing, then they can use it.
So, I built it because I needed it for my own use. I was NOT going to rewire the system and definitely wasn't going to get any DC valves. Plus, the challenge of building the darn thing was an added bonus.
Well, a neighbor saw it, asked for it, and then one thing led to another and here it is!
Maybe this can save someone some digging, some frustration, and some time that goes with debugging bad wires and such.
