I have had my Canon 20D lock up 5 times on different occasions filming coils where I had to remove the battery to "reboot" it since it got hung up. Of course I had it lock up under the 345kv lines at work too and in a 500 mRem/hr radiation environment too. So maybe my camera is more sensitive to these things. The digital Sony video camera occasionally gets some effects. On one occasion the camera had a bunch of menus pop up on the recorded video. When heavy ground strikes occur, some additional electrical noise (hiss and pops) is picked up audio circuits.
I think making sure that the coil is tuned up well and making sparks is probably important too to reduce the radiated noise that will affect the cameras.
It can be pretty amazing how electronics respond to intentional abuse.The Geek Group did a thing where they were hitting a computer running windows with streamers from a big coil. It was doing pretty well. Started to reboot a bunch of times and then eventually died. But I think they had to remove some metal in order to really get it to die.
The great pictures that you can get from that camera is worth the risk. Good luck Neal. Jeff Neal Namowicz wrote:
