Re: [TCML] 2008 Tesla Fest aka Lightning on the Lawn



Okay. I should have my coil done by then. 

So for power hookup what are we looking at? 

I am designing my coil to run off a standard four prong 50A 
stove outlet. I don't want to push the PT past 30A or so and
the ballast is only using #10 wire, so maybe we pull 50A for
a short period but nominally 30A. ASRG is gonna pull about
10-15A through a separate circuit.

The coil is basically %90 done, now I'm working on the power
control components, ground, finishing safety touches etc...

I just measured everything physically and electronically (LCR) 
and fed it all into JavaTC and it looks great! (attached.)

Have you got any 6x7x8" x 24"ish spun aluminum toroids that 
you'll be wanting to get rid of? :)
