This weekend I spend most of my time working on the primary coil for the Tesla coil. I was very surprised that I actually managed to get this done.  It is made from copper piping and a hacked up cutting board.  I found it surprisingly fun figuring out the best way of assembling this.  Though I have to admit, I made a really stupid mistake when buying the copper, turns out the circumference of a circle is 2*Pi*r, not Pi*r.  An embarrassing mistake that ended up giving me exactly half the copper piping I needed for the coil.  As the old adage goes calculate twice, cut once.

This will be used in a series of videos that will be posted to YouTube, assuming everything works.  Which is a big assumption.  Fingers crossed that this makes one kick ass piece of demo equipment and not a death trap.
