Green Meanie SSG and SRSG

Green meanie because this coil has an angry spark gap.
SSG: Static Spark Gap
The very basic type of coil, a couple of NST's, a capacitor bank, and a spark gap, as can be seen the 'powerwall' provides the motive force

SRSG: Synchronous Resonant Spark Gap
This uses the same powerwall, but instead of the static spark gap, a rotary gap is used, basically a motor to spin a disc that has electrodes to make and break the gap, but the motor synchronises to the mains frequency with a bit
of modification.

The primary for both of these coils is the same, it is also made from acrylic, The arm slots were made in a jig that fits on the router table, these were screwed from underneath to the base disc. And of course I wanted to be different with the strike rail supports, so acrylic rod was used, I made a former from wood, then heated the rods over my 100W soldering iron while slowly spinning it, when it started to soften, I placed it in the jig and bent it to the desired angle, the rods are fitted into holes in the disc and epoxied.

Being acrylic I wanted to make it glow, I chose green led's, there's a ring of 6 to light the disc, 6 more pointing up to light the secondary, then there's 2 sets of 6 individually wired for the arms and strike rail supports, the latter sets connect to a couple of 4017 ic's to make them rotate., how long the ic's last when the coil is powered is something to find out.
