I thought the automatic F made his intentions pretty clear. It was the same deal with 'goto' statements in any high level programming class, instant F.

The problem with one shot timers is, they are temperature dependant, voltage dependant, and rely on the RC time constant, which also can create a wide range of tolerance issues.

The real problem with one-shot timers is they act sort of like digital circuits, in that they have two states: on and off. BUT real digital logic is controlled and regulated by a clock. Every state should be registered relative to a well defined clock

a one shot timer by contrast is more like lighting a fuse. Asychronous logic is one of the fundemental causes of system instability, design bugs, and system failures. Its better in the long run to design a good, deterministic digital solution (with a clock) than to mess around with asychronous logic. You end up spending more time and money designing and debugging asynch circuits than just doing it right the first time.

hence, the automatic F :^)
