I don't think we can count on the magnet leaving as being a safety feature.

If a stray magnet goes by it will trigger the spark no matter what we do. Rising edge, falling edge, or even both will end up with the same effect. The only way to prevent accidental firing would be measuring the length of the activation and only firing if it fell within the proper range.

I don't think even that would work because transient magnetic fields would still set it off since they would likely be very short and fall within the timing range. If I can figure how to make the unit safer I certainly will. With the new 1840 chip we'll have the processing power to make more measurements and handle things in a smarter way.
