My Raspberry PI-based pool controller has been running our pool pumps faithfully for the past 18 months. Every morning, it switches the two pumps on (first one, then the other), and runs them for a few hours (switching them off in reverse sequence). It is really nice to sit out on the deck, go to…
(Previously I discussed the the why of this project, the parts I selected to build with, setting up the Raspberry Pi itself, the electronic assembly, the mechanical assembly in the backyard, and the Rasptimer software I wrote for it.) Here’s the project bill of materials, not counting things like that I replaced or improved “while…
(Previously I discussed the the why of this project, the parts I selected to build with, setting up the Raspberry Pi itself, the electronic assembly, and the mechanical assembly in the backyard. Now we need real software to run.) So far, I’ve switched the pumps on and off with the way of least resistance: piStatus.pl.…
(See post on the why of this project. In this post, I describe how I arrived at the picking the parts that I did, assuming it might be useful for others considering similar projects.) I start by investigating suitable hardware platforms, and quickly figure it will have to be either an Arduino or a Raspberry…
(There will be more parts.) Here’s my problem: The filter and the sweep of my pool need to be run every day for a few hours. The corresponding pumps are controlled by two electromechanical timers, one of which failed recently after probably more than 20 years of service. (Timer shown to the right.) Turns out…
