Some weather & energy data has been coming in over here for over a month now, logged to text files, and patiently awaiting further processing. Here are the results of a few days of hacking around on the software side of things:

This is a test page served by a custom web server, with all data now stored in a database. I’ve used several bits of software which are dear and near to me:

  • the database used is my own trusty Metakit
  • the custom software is written in Tcl
  • the web server is based on my Rig modules
  • the plots are generated in the browser by Flot
  • it’s all in two files using using Tclkit / Starkits

The code is portable and works on Mac OS X, Windows, and Linux. The system requirements are minimal, so it runs just fine on my NSLU2 and Bubba NAS boxes.

Things are starting to come together nicely…
