February 5, 2021 Update: Project Ghost Eagle continues to be my focus.  This week I made good progress on design of the fire control group.  I also filmed a quick video following up on my study of practical accuracy and beginning to look specifically at the effect of optics on practical accuracy, and I recorded some footage for a video I plan to make about working with agates and other semi-precious rocks that I frequently find here in Idaho.  However, I'm still working on filming the agate study, and then I'll have raw video for about three episodes that I need to get around to editing.  Anyway, this weekend I think I will upload the video I made about building a solar dehydrator.
