Please keep the [OT] in the subject, unless you go back directly on pics, so people who want can filter the fringe discussions.. Interesting aside, (I have a friend who survived a double chute failure by managing to get 1/2 of the reserve chute open, so I have an interest in that area. BTW, he has never since jumped out of a good airplane. Decided not to do it again when he looked up and saw the reserve spiral wrapped around the unopened main chute..) but the example was a rough one to try to illustrate the problem with the logic, not to give a good example for it. About the last place I'd want a microcontroller.. Alan Dave Mullenix wrote: > I vote for a loud "BEEP!" when something malfunctions. > > Dave Mullenix
