modularizing chuck files

Nikolaus Gradwohl2009-01-17T13:11:00+01:00

I wrote a simple chuck script that generates a drum loop and a bass-sequence. later i wanted to reuse the sounds and started to search how to modularize the code.

so i started to convert my instrument declarations in classes. The instrument classes don't get connected to 'dac' directly. They have a "connect"-method that can be used by the main script.

to run the loop all the scripts must be given on the commandline

chuck Bass.ck DrumSet.ck loop.ck

The main script (loop.ck) instanciates a DrumSet and a Bass class and connects them to "dac". Than it generates a walking bass and a simple electronic drum loop.

DrumSet drm;
drm.connect( dac );

Bass bass;
bass.connect( dac );

[ 41, 41, 44, 46] @=> int bline[];
0 => int pos;
0 => int count;

while ( true ) {
    drm.hh();
    if ( count % 2 == 0 ) { drm.bd(); }
    if ( count % 4 == 2 ) { drm.sn(); }

    if ( count % 2 == 0 ) { spork ~ bass.bass( bline[ pos % 4 ]); }
    if ( count % 2 == 1 ) { spork ~ bass.bass( 12 + bline[ pos % 4 ]); }


    1 + count => count;
    if ( count % 4 == 0 ) { 1 + pos => pos; }
    250::ms => now;
}

I recently installed python3. While scanning through the module directory a package named "antigravity" catched my eye.

when i typed "import antigravity" python opend a browser-window with this link

i really like python - and xkcd :-)

Visiting the Mailüfterl

Nikolaus Gradwohl2009-01-11T16:10:00+01:00

Today i was visiting the Technical Museum of Vienna and while standing in front of favourite exhibit - the Mailüfterl which is
the first european full transistorized computer - i thought it would be cool to see some code running on this machine.

back home i googled a bit and - tata - someone has written a emulator of the mailüfterl!

Training Bike Visualization

Nikolaus Gradwohl2008-12-08T14:58:00+01:00

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.

processing ical-flowers

Nikolaus Gradwohl2008-12-06T22:42:00+01:00

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

Nikolaus Gradwohl2008-12-06T22:26:00+01:00

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.

where do my readers come form?

Nikolaus Gradwohl2008-12-05T05:35:00+01:00

out of couriousity i took the access.log from my blog for the last 5 days, extracted the ip-adresses and looked up the countries my readers come from using hostip.info

so here is a list ordered by count of uniqe ip-adresses. (i even have readers from andorra! more than from swizerland and austria together!)
