I'm still sweeping away, getting lots of random things done. Praise the Lord for time to do this! I even had a chance to work on the PIC/PC data transfer code, which I enjoy.
I saw some solar cells from Edmund Scientific that output 8.5 V at 250 mA. That sounds fairly attractive, since it should avoid most of the boost/charge pump frustrations for the team.
I got an e-mail from a faculty member adopting the book I co-authored. That's very encouraging!
