I normally don’t play much with hardware, mainly because there isn’t/wasn’t much I want to do that tends to require hardware that’s not a regular PC or maybe a phone or tablet. This one is different, because no self-respecting geek would want the usual rotary control “programmable” timer to run their sprinkler system, would they?

We do live at the edge of the desert and we have pretty strict watering restrictions here. I’m all for it - water being a finite resource and all that - and I want to improve our existing sprinkler system at the same time. It doesn’t help that the people who set up the sprinklers were probably among the lower bidders, to put it politely. OK, to be blunt they seem to have failed the “giving a shit” test when they put the system together. I’ve spent a lot of  last year’s “gardening hours” just trying to make it work somewhat. Not well, just “somewhat”. Time to fix that.
