Here we have early projects. These were the first scratches of the paintbrush. Art? Sometimes yes, but often, no. What mattered was that they worked at some level, and taught me new things for the next go-around. These projects were the foundational experience for all that followed.

The highlight of this section is the subwoofer article. It has some rough edges that properly qualify it for the "early projects" section, but it also represents a transition point. Nearly everything that came after it took on a noticeably improved form as a result of what was learned during the year-long subwoofer build.

Please pardon the lousy photo quality throughout. I didn't have any good digital cameras until much later, so it was kind of impressive that some of this stuff was photographed at all. §
