Yep, blown two garage door openers, wiped my Alarm system memory and blew
a stereo in the garage. Wife will not allow me to run coils in the garage
now, so out in the backyard @ http://www.youtube.com/watch?v=BDqPdNdE6L8 .

Working for Intel designing new chips (22 years now); the gates are
getting smaller and smaller. Great for speed and power reduction, however
the gate oxide is so thin it does not take much to punch a hole. Keep
Tesla coils total away from electronics to be safe and the wife happy!

I did the same. Blew one of three or four boards. It
cost $85 to replace. As far as I know, there's not
much you can do. If you have a removable antenna
that'd be a good place to start, but your whole door
and frame are probably a giant antenna. I've turned on
my neighbor's flood lights at nearly 75 feet away, set
off battery powered alarm clocks around 25 feet away,
killed a computer PSU, and have seen wrenches on my
wooden bench arc to each other while my coil was
running ten feet away.
