In order to document the sensor apparatus for students to understand, I had planned to draw a schematic in Eagle. Last night, I ran across Fritzing, though, and thought I would give that a try. The results are edited a bit. Fritzing didn’t have a part for the magnetopots, so I drew one — hoping to create a part out of it. Unfortunately, when I tried to follow the part creation procedure, I found that the Fritzing part template file appeared to have slightly less that 1 mil hole spacing, so it wasn’t compatible with the part I drew. Bummer, but maybe it saved me some time in the end?

I wrote two programs which demonstrate the basic workflow necessary to create a movie with a transparent background.
transparent_png_writer_bare.zip contains a Processing sketch which writes out a variable sequences of .png files with a transparent background.
framewriter is a Max patch that loads all of the .png files in a specified directory and dumps them frame-by-frame into a .mov file encoded using the “Animation” codec (which supports transparent backgrounds).
