Build Your Own Tesla Coil

screenbert writes "Ever wanted to keep stray dogs or neighbors from trampling your backyard, but just couldn't find the system to really deter them? Well this site shows how they built a bi-polar Tesla Coil system. I've always loved the Tesla coils on C&C when they'd zap the units as they went by. "

Everyone's afraid of a new class of terrorism that seems to be emerging. Bombing and shooting people is for dumbos. These days, smart terrorists disrupt the use of technologies like phone, cell phone and computers. This is a device for them. Imagine this device placed near a major phone line hub... within view of a cell phone transmitter... on a highway bridge, the latest "drive-by-wire" cars passing beneath it... on an airport... at a stock exchange... Devices like this, at a handy size, could be as dangerous to economics as a gun is to an individual. I wonder if there is a law against things like that.
