  • Wes will be giving a demo of how the learning structure will be conducted going forward from this point.
  • Students will learn what pieces of equipment they may purchase to participate.
  • The cost for all components is estimated to be from $75 to $150 depending on what options the student selects.
  • Wes has written up a blog post to loosely define his idea of how we will be proceeding.
  • Wes has prepared a lecture for this first session on capacitive reactance. The experienced electronic technician will be bored to tears with the lecture part but the lab part makes up for it. You will get a solid feel for what the Smith Chart is all about. Likely we will not get that far saving it for next week. More than likely we will spend the entire hour learning the basics of the nanoVNA and giving students a better idea of what they ought to be buying for this class.
  • More than likely, in next week’s class we will be repeating what was intended for this week. I expect that we will bogg down in the nanoVNA itself, the fragile patch cables, and the RF Demo board itself. The notes slides shown at the bottom of this page will, no doubt, be refined.
  • But there is also a good case that can be made that in TWO weeks (class after next) we will still be on the first element of the RF Demo Board (the LPF). This is because there are many, many ways that what we have observed with the LPF relate to the nanoVNA. Recall, the purpose of the class is not to learn the nanoVNA but the Smith Chart.
