Re: Garage door opener vs. Tesla coil

Thanks everybody for the many suggestions on protecting garage door 
openers and also for ideas on not getting the wife mad about coiling 
mishaps (as a side note - surprisingly, she didn't get as upset this 
time as she did the last time my TC destroyed something.  Maybe she's 
getting used to it...at any rate, I don't want to push it).

I will try a number of your suggestions.  I guess the salient point 
is that coiling at increased power eventually gets to a point where 
you just don't plug it in & go.  Set up & damage prevention measures 
now seem to be taking more time than the time I spend actually 
running the thing!  Dennis Hopkinton MA

Dennis,
I had a similar experience with loss of a garage door opener circuit 
card from my TC operations. The coil was far enough away that it did 
not strike the opener but the receiver apparently did not like the TC 
RF emissions. The replacement card was $90 and my wife was not too 
keen on using the push button operator I rigged while waiting for the 
new card.

I now always unplug the door opener when I run small coils in the 
garage. When I run my medium coil (which does strike the opener 
rail), I unplug it and remove the PC card. - after dozens of runs at 
different times there has been no further loss.

I looks like my coil murdered my garage door opener. While running
the coil in the garage, the garage door opened on it's own & then
died. I now have to open & close the door manually. I was careful to
position the coil far enough away so that no arcs could strike the
opener or anything connected to it, and it still seems to have
succumed to the coils effects somehow.

My question is, other than unplugging the opener, are there any
preventative measures I can take to protect the garage door
motor/receiver? Or is there just no safe way to run the coil indoors?
I imagine the repairs won't be cheap so I'd like to avoid a
repeat. Thx for any advice. Dennis Hopkinton MA
