Hi All -

I need to throw in some cautionary statement. If you click on the 
sparklength text in the RSG and Static Gap sections in Javatc, I show the 
method used to identify the sparklength discussed. I also indicate the 
equation is experimental. The accuracy is not known without a lot of 
comparisons, and there haven't been enough comparisons to make a 
determination. I want everyone to be aware of that.

While I'm on the subject of Javatc. There will be an update coming soon to 
the Static Gap Arc Voltage. Following Dr. R's spark gap measurements, I 
started investigating as much work on the subject as I could find. This 
past month has been spent studying spark gaps, arc formation, streamer 
formation processes, etc... One thing I've learned is our sparkgaps 
settings can vary more than I expected. I have updated this section in 
Javatc to include sphere-sphere, sphere-plane, rod-rod w/hemispherical 
ends, rod-rod w/ flat ends, and rod-rod w/ flat ends slightly rounded. I 
haven't uploaded this update yet, but it finished and will be coming soon. 
The current sphere-sphere isn't much help to anyone as it pertains to 
spheres. Also, pipe gaps probably won't be possible. Arc voltages just get 
too nasty with all the variables involved with these gap styles and they 
increase with each cylinder. In the end, the best method has been and may 
always be calibrating the gap to the transformer.

I'm currently in the process of trying to help out a Mac user. There are a 
lot of problems if browsers have Java Sun loaded (Opera, Netscape, 
Mozilla). Java Suns JVM is less tolerant when passing arguments between 
java and javascript. Thus, the drawing applet often fails to work (except 
IE6 [unless IE6 is using Java Sun, then it fails also.]). When I upload the 
update, your browser will be sniffed and if it's not IE6 or up, then a 
slimmed down version without the applet will load which will hopefully 
enable most browsers to use Javatc (say 4.x and higher), well assuming we 
can can the Mac up and running.

Take care,
Bart
