Sounds to me like we can skip something electronic for the day. Most of us want to try cornstalks, and we all need tombstones. Somebody does need to yell 'focus' at us now and then. There is only 2 weeks left to decide, and we are still discussing cornstalk supplies. Electronics would be a day on its own due to the complexity.
We may need to experiment with different cornstalk methods, which sounds easy but may need more time than you would think.
If we want to add one other project, than a simple static one would be best. Not Sams, not everybody wants one of those. I can make that on my own following other people's directions. If see if I can come up with something by this weekend.
