Training Bike Visualization

Nikolaus Gradwohl2008-12-08T14:58:00+00:00

i wrote a processing sketch to visualize and record sessions on a training bike. To calculate the rotation-speed of my training bike i hooked up 2 reed-switches to my arduino and taped them to my training bike. Than i sticked a rare earth magnet on each pedal.

the processing sketch draws a small figure on a bike which is animated at the same speed as the bike.

the sketch also records the timestamps to a log file for later analysis.

ical4p Processing lib

Nikolaus Gradwohl2008-12-06T22:26:00+00:00

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.
