Hi, I just discovered this site and it Rocks! I've got several projects I'm working on right now and I wonder if anybody has feedback on these ideas.

  1. A better (cheaper) Batt-Latch - basically just a timer that releases a pin, from there the Rube Goldberg possibilities are endless.

  2. Hypar roof for chicken tractors - advantage being perfect rainwater catchment in the low corners, disadvantage is difficulty covering it with a flat sheet, and vulnerability to high wind.
