Project MoodJar: Aluminum Solder Joints

In my last post, Capacitive Touch Testing Platform, I experimented with soldering to aluminum. I had read about all kinds of tricks for such soldering: solder under oil, scratch the surface with a wire brush first, etc. I cheated and scratched the surface of the aluminum with the iron under a ball of solder. This post is just about the resistances of those joints, as well as some finishing touches on the CTTP.
