weeWX: open source software for your weather station

  • Some schools did experiment with a change in methodology ie how to teach students today. They are going for project based teaching. One of them could be the setup of a weather station! Obviously it involves the collaboration of several teachers and students but that is a great asset for students today as nobody can work all alone. They see the example of teachers helping each other. They see various students giving their input,comments, questions…..and that makes teaching and learning real fun!  It could be the best preparation for their future when they would be called to work with different type of people!

    Today we are presenting an open source program called weeWX. On the same page one can: download; read documentation; go through the users’ group; learn how to publish readings etc…...If one prefers youtube videos in order to learn, here is the link. An interesting factor is that most schools are using the raspberry pi 3 in order to maintain the weather station!!

    The weeWX program can do several things:

  • Support for many popular weather stations;
  • Uploads to popular weather sites including WeatherUndergroundPWSweather.comCWOPWOW, and AWEKAS and others;
  • Uploads to your website using FTP or rsync;
  • Extensive celestial almanac;
  • Ability to create or modify skins (the look and feel of your weather site);
  • Support for localization;
  • Simple, but extensible templating system;
  • Native support for US or Metric unit systems;
  • Support for sqlite or MySQL databases;
  • Calibration corrections;
  • Filtering of anomalous values;
  • An easy to understand, simple, extensible micro-kernel architecture;
  • Ability to extend weeWX with new services and reports.

    Creating and maintaining projects in school : GanttProject


    Some schools are leaving the lecture lesson type and moving towards the hands on experience. Not only students need to work directly on a project but they need to work with others, collaborate and change throughout the experiment. It’s the learning process where students learn to edit all the way through, as they interact with other students and teachers.

    The world they’re going to work in one day, is based on projects. Hence it makes sense if they start preparing for the future. Today we’re presenting another tool in the hands of educators in order to help their students write their projects: GanttProject. Some functions done by GanttProject are:

    • Create tasks and milestones. Aside from the start date and duration, every task may have priority, cost New in 2.7, color and fill pattern, text notes and user-defined custom fields.
    • Organize tasks in a work breakdown structure. Hierarchical tree where progress, dates or costs of lower level tasks is summarized on the higher levels. Summary tasks can be collapsed to hide tasks which are not important at the moment.
    • Draw dependency constraints between tasks, like "start X when Y finishes" and GanttProject will take care of enforcing these constraints. You can add a lag or use other types of constraints.
    • Create baselines to be able to compare current project state with previous plans..
    • PERT chart for read-only view can be generated from the Gantt chart.
