I am slowly constructing my first intelligent instrument. It will be an instrument that learns the acoustic radiation pattern emitted by a speaker. It is not a perfect acoustic experiment—nor is it meant to be. Uncertainties and errors abound, especially since I am using the Lego NXT Mindstorms system to construct the instrument.
The design is sufficiently complex that I found that I need to document it using the LDraw system, specifically MLCAD. I have been practicing my animation skills as well. Here you can see a short animation of the central drive shaft for the acoustic platform. The gears are turning at the appropriate rates and everything. However, there is an aliasing effect in this downsampled image (which used to be referred to as the wagon wheel effect). So it may look as if some gears are rotating backwards, or not at all. If you click on the image, you can download a 6 MB version that is much smoother.
The longer animation will appear in two talks I am giving at the University at Albany this week:
NTIR 2007 and PASCAL 2006.
