We have a nice big tree in the front garden. For Christmas I set it up with some tinsel and a star on top. Of course the star has to turn on at night and back off in the daytime. I could have used a cheap wall timer, but in the spring I want to build a more sophisticated controller for watering our plants which knows about the weather etc. So I ran some speaker wire and set up a Pi to do scheduling.

Wiring pieces together and writing code doesn’t take very long. Most of the time is spent

  1. Tinning wire, and
  2. Debugging group permissions for GPIO on the RRi

Why does the world work like this I wonder?

Code is here.
