Dave,
One time I went to the Microchip Master's Conference, a guy gave a talk
about how he makes fuses for high end fireworks with PICs. These PICs ride
in the fireworks and then detonate them at the right time. Pretty cool how
he does it actually. Anyway, he had the same issue, and he just potted the
whole thing and never had any problems after that.

Hi

This is a bit of a strange question. I keep stumbling into strange (but
interesting)
projects to play with.

What is the maximum vibration level and/or G force standard smt or thruhole
will tolerate ?

I've been asked if I could figure out a electronic detonator for an
airburst charge
for snow guns. These are the guns/mortars they use to fire 4-8lb charges at
potential slides to trigger them. The trigger will be a pic that simply
counts
and then fires a electric match after the preset delay.

I'm hoping this will prove tremendously difficult so I get to "work" and
have to blow
things up all winter ;-]

Tia
