processing ical-flowers-2.0

2009-02-15T08:15:00+01:00

I made a new version of the ical flowers sketch i wrote in dezember. This time it doesn't only show a flower for every event in my calender, it also shows

the current weather (using the rubyweather library)
the current temperature outside
the min/max temperature outside
the current temperature inside ( using my arduino i2c thermometer sketch)
the sky color changes depending on the current time

the system consists of a ruby-proxy, an arduino sketch and a processing sketch.

the ruby proxy starts a web-server on port 2000. It fetches the current weather using the rubyweather gem, fetches the events from the configured caldav calenders, and fetches the current temperature from the arduino using ruby-serial

the arduino sketch is basicaly the same as in this blog post. the only change is that the arduino only sends the temperature when the host sends a 'C' over the serial line

the processing sketch finally fetches the data via http from the proxy and displays it ( using my icap4p library. the screen is updated every 1/2 hour using the method described here

the code can be downloaded here

it's published under the LGPL

have fun :-)

I just made a processing sketch using my ical4p library. The programm draws a flower for every event in a given ical-file. The more events the calender has, the more beautifull the flower-garden is :-)

ical4p Processing lib

i have written a small wrapper around ical4j written by Ben Fortuna. This allows to write processing sketches, that visualize data from ical files.

i included a small example in the lib showing how to draw a timeline based on an ical file.

i also have set up a project-page for it. The libray is released under the LGPL.
