Site prototype 2 / Workshop Open Circuit
Tuesday, October 20th, 2009
So, what I’m currently working on is a website for my prototype 2, a wiimote gestural MIDI/OSC controller made in the scope of my master’s thesis. The site will feature some explanation about the concept and source code for anyone interested in using it/developing it further.
This weekend I also went to a kickass workshop in KC België (Hasselt) that was about circuitbending, chiptune, and everything related. We (Jim Bollansée, Danny Leen, Tom Luyten, Peter Briers, Ruud Denivel, Olivier Berger and me) got our very own private workshop from Jethro Volders (The Rottchilds, El Guapo Stuntteam) to create visuals for the The Vermin Twins (Lotte Vanhamel – Micha Volders (The Sore Losers, El Guapo Stuntteam)) performance at the end of the workshop.
We followed a tutorial made by little-scale (Sebastian Tomczak) about hacking VGA plugs to send out RGB signals of your own via an Arduino.
More info and a video after the break!

Processing sound libs problems #2
Saturday, April 18th, 2009
I sent an email to Damien from the minim library with a recording of the glitch, and here’s what he said:
“Ugh, that is a weird glitch. I’d agree that it’s not buffer underrun. It
probably has something to do with the particular version of Java you are
using on your particular macbook. My understanding is that Apple has not
been very good about keeping the JVM for macs in good shape.”
Also, I got some proper sound out of it after I started up Ableton Live to record the glitch. But as mysteriously as it got fixed, it got broken again. Maybe I should switch to a windows system for this prototype. Or Pure Data, I haven’t decided yet.

Processing sound lib problems
Wednesday, April 15th, 2009
The Minim as well as the Ess library, how great they might be, both produce really strange glitchy sounds that aren’t part of the waveforms. Currently thinking of switching to Pure Data for the synthesizer.
In other news, I’ve checked out gesture recognition with wiimotes. There’s a java library that focuses on this, WiiGee, but it doesn’t support multiple wiimotes — edit: it does. So I’m checking out Hidden markov models and their use in gesture recognition. Since this is computer science stuff it’s a bit over my head…
I’ll keep you posted! The waveshaping synth prototype should be finished soon.

Processing sound libs
Sunday, March 29th, 2009
I’m trying to get the waveforms I draw in processing into some kind of oscillator using the minim library. Somehow it should work.
I also added some toggles to my wiimote analysing app for easily comparing waveforms. (click for a full scale version)
I’m also preparing for the trip to Berlin this week with school from monday to thursday. Weela!

Processing wiimote analysis – Prototype idea
Friday, March 27th, 2009
I made some applications in Processing to further investigate the wiimotes, and how they react to different movements. I’m using all of the indications of movement possible with the wiimote (except for the IR camera, for freedom of movement); Pitch, Roll, Yaw, overall Acceleration (these are calculated by OSCulator) and also the raw X,Y,Z accelerations.
While waving the wiimotes around I noticed some things. If you’re making round movements, the graphs become a fluent curve, almost a sinewave sometimes. If you’re moving really wildly, it gets closer to a sawtooth or pulse wave. This made me thinking that maybe the most direct connection between your movements and the sound that you produce, is through these waves that you draw. The “buffer” above is 500 samples long. In a second of “CD quality” sound there go 44100 samples. So if you repeat one of these waveforms 88,2 times per second in an oscillator, you undoubtedly would get a very “own” sound.
This is definitely something I’m going to explore, I can barely wait!
