My Raspberry Pi Pool Timer Project — Bill of Materials
(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…

My Raspberry Pi Pool Timer — Software: Rasptimer
(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.…
