Did more research on the RF lightning detector and looked at some options for the flash detector.
I plan to keep both simple so that they are easy to build for others interested in duplicating my work.
I was hoping to make some measurements over the weekend, but in true murphy fashion, none of the thunderstorms triggered.
I also ordered part of my surprise.
I will get some pictures soon, but in another expected result, the camera battery was dead.
I am encouraged that the other people in the challenge are getting their boards and their projects underway.
Looks like some good applications.
