I remember freaking out another techo doing a Magnetotelluric (MT) survey in Indonesia - I took a photo (with a flash) while he was sitting in a small tent with a laptop hooked up to sensors that were in turn hooked up to several thousand metres of copper cable. Lightening storms tend to make these guys _very_ twitchy despite the isolation devices. I have to agree with Steve that you should be a little careful about stringing out your own copper cable - you might be fine (esp around Auckland), but a lighting strike passes a hell of a lot of current. --gb ------------------------------------------------------------------- To remove yourself from this list, email nzlug-request@linux.net.nz with "unsubscribe" in the body of the message.
