My Pool Timer is working fine in the back yard. It's really cool to drive it from a web browser, and track when it's running graphically. The Raspberry Pi is working fine. But, the Raspberry Pi is really not the answer for this kind of project. In fact, I'm not entirely sure what project the…

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.…

My Raspberry Pi Pool Timer — Mechanical Assembly

(Previously I discussed the the why of this project, the parts I selected to build with, setting up the Raspberry Pi itself, and the electronic assembly In this post, it's getting serious: I put all the parts together in place in the back yard.) Recall that I got into this project because an old electromechanical…

My Raspberry Pi Pool Timer — Electronic Assembly

(See this post on the why of this project, this post on the parts I selected to build with, and this post on setting up the Raspberry Pi itself. In this post, I describe my travails assembling the electronics.) Disclaimer: don't do what I do in this post. It's not safe. You or others might…
