Day 74

Morning
Getting to work on S9 beam patterns. I had Dean help me with the work order so I could go down to North Coast and buy an end cap for the Compact Logix here in the office. After getting stung by a bee in the truck, I got my cap and put it on. With minimal fiddling I managed to get the unit working. With some plc programming I was able to make cosine waves and other oscillations on the oscilloscope. I was even able to make the full equation that I wanted. I realized that it would be impossible to make a parametric view of this that would show what the beam pattern will look like.

Afternoon
I worked on the documentation for the beam patterns. I wanted to get a pot on the plc, but that will have to wait until tomorrow. I wrote up all of the math concepts (two waves with tunable frequencies). I haven't hit any problems yet. I also took a :30 minute ethics course online. I don't know where they come up with some of these things, but if they want me to watch it, I guess I will.
