Hi All,

I didn't take any photos of the Maker Faire event but here's a few that 
have surfaced on the Web, which are usually better quality than I could 
produce anyway.  This was a daytime event, and though the ambient 
lighting washed out most of the finer streamers, the event offered an 
opportunity to shake down the system for the first time and explore some 
of the interesting twin coil dynamics.

It was a pleasant change of pace to setup and run a simple coil system 
where everything is hand-carryable. The two coil structures stand about 
10ft high and 18ft center to center.

Here's the power supply and timing controls:

Here's a pic from the one time we were able to dim a few courses of lights:

Here's a closer view of the arc structure:

And here's a video clip of the coils operating.  Again, sorry about the 
ambient light!
