Re: [TCML] Pictures of my Tesla Coil

["Barton B. Anderson" <bartb@xxxxxxxxxxxxxxxx>]

Hi Ed,

Power on those particular photos is in the range of 1500W (much more 
than Dirks coil).

It is a powerful little coil. Important to keep the garage door open for 
ventilation (especially during my endurance runs). I've had no problems 
at all. But, I did manage to put too much power to the little coil and 
cause it to burn. I fixed this by removing some of the bottom secondary 
turns (the burned area). This reduced k a little (3/8"). It burned a 
second time and I did the same. After this second removal of turns and a 
little lower k, I've been able to run this coil continuously for 30 
minutes without problems. The sparks are still just as long and powerful.

As a matter of fact, I ran it last night for about 5 minutes continuous 
(for giggles).

That little coil is painted demon red these days. In some of those 
photo's you probably saw the streamers hitting my slightly larger coil 
next to it (my 8.5" high turn coil). What I did was ground the larger 
coils toroid with a wire (to send those sparks safely to ground). It 
also provided a grounded target in the process. So of course the sparks 
found their way to that coil.

Take care,
Bart
