Thoughts

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.

I've been working on a project for a while now... about a year or more. Originally, I was going to call it SunJar, but that concept has already been developed and sold, and I intend to incorporate more functionality. And color. So it is going to be called MoodJar. Anyway, the last post I had on it was quite some time back, when I talked about solar cell characteristics . This post is going to be about the capacitve-touch I intend to incorporate.
