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…

My Raspberry Pi Pool Timer — Setting up the Raspberry Pi
(See this post on the why of this project, and this post on the parts I selected to build with. In this post, I describe setting up the Raspberry Pi itself.) Update 2013/01/12: Using wpa_supplicant to automatically reconnect to WiFi base station when needed. This turns out to be remarkably simple: Steal the HDMI cable…

My Raspberry Pi Pool Timer — Selecting the Parts
(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…
