Went to hear Steven Mitchell play class at the National Ballet of Amsterdam today. He has a rich sound and strong touch--quite nice to listen to. Afterward I went to the Flea Market behind the opera house to pick up a few things, including a Hi-8 video cassette with case. I promptly threw away the tape, because I just wanted the plastic case for a portable wireless sensor prototype (more on that story below). Then this evening I saw a performance by the Netherlands Dance Theatre. What gorgeous dancers! And really nice choreography, very sophisticated high Euro-style. Back to the sensor...I want a wireless control button that I can put onto any instrument I'm playing anywhere in the space, for recording loops into my new Max/MSP looper patch. So after I came home from the flea market, I went into the STEIM workshop and put this little baby together. Jun here is so helpful—he uploaded a new sketch to the Funnel i/o (I don't know what I'm going to do when I get home, because this is custom code and I'm not sure I can get it from him) and gave me a switch for the gizmo. He then gave me a place to work, and a little while later, Violá!—I had the sensor finished. It works perfectly. I put velcro on the drum, and it's cool how I can just move it around, and stick it to instruments that I have at hand. It's not as full featured as a wii, but it's light weight (eventually I'll get it to be much smaller (Arduino minipro, xBee, smaller battery) and I will be able to quickly stick anywhere. I might just keep it to one switch only—just that, a one-purpose thing, bucking the trend of one thing doing everything.

The case is great for prototyping because it has a nice door for accessing the electronics.
