Davis Vantage Pro2^TM Weather Station

The basic Vantage Pro 2 includes an integrated rain collector, temperature and humidity sensor, and an anemometer.

The Vantage Pro2 software provides forecasting features, a wide range of on-screen graphing, a variety of measurement systems, and much more than can be describe in this brief post. The web page located at http://www.wsd1.org/weather/ shows the data that can be collected with the basic Vantage Pro2.

Scratch is a programming language from MIT’s Media Lab that makes it easy for students to develop programs.

Scratch is not so much a procedural language as a drag and drop environment for creating interactive animations, annotated stories, slideshows, prototypes and games. It’s designed to be as simple to use as possible, so students as young as 7 can create their own animations.

The design philosophy behind Scratch was “don’t design something for kids that you don’t also find engaging and interesting,”

To create programs in Scratch, one simply adds “sprites” onto a work area and then attaches actions to each sprite to make them move, change color, bounce off other objects, and make sounds.

Scratch is available for Mac OS X and Windows, and can be downloaded for free at scratch.mit.edu.

Scratch Extensions – New Versions by Other Authors (blog site)

• BYOB – A version of Scratch that allows one to create their own blocks (updated – based on Scratch 1.4)
• Some of the features of BYOB (these features are unique to the modified version of Scratch 1.4)
  • custom blocks (functional recursion)
    • includes majority of Scratch 1.4 features (esp. string functions)
    • can open/import any Scratch project
    • arguments now take  both numerical and text input (and reporters)
    • double click on a custom reporter block to show its result
    • the block editor’s answer field includes drag & drop functionality
    • improved debugging functions (error blocks are displayed red)
    • escaping out of infinite atomic loops
    • block editor is resizable
  • nestable sprites (structural recursion)
    • create composite sprites (made out of subsprites)
  • • sprites can be nested infinitely, making them “parts” of more complex simulations
    • subsprites follow their owner’s motion, heading, resizing and graphical effects, and serve as their owner’s extended sensors
    • subsprites can be set to follow their owner’s rotation, or to rotate independently
  • other
    • share sprites in a mesh network (this includes nested sprites)
    • built-in compiler lets you convert any Scratch/BYOB project into an .exe (Windows only)
    • autoscrolling
    • scrolling by dragging
    • undo
