Sorry for the newbie question,

But will this kit be beginner friendly and how long until it's released?

Thanks,
jazzman

Our goal is to make it as beginner-friendly as possible; expect a launch in the next couple months.

 		That's a great design! I admire your work. I've recently started playing around with the FGH60N60SMD myself - amazing part. The only time I've killed one it was a deliberate effort in a test jig.

 		An interesting phenomenon: ground strikes appear to propagate like lighting, with a leader starting from the ground and extending to meet the streamer from the coil. At least that's what my camera says...it could be a figment of my imagination, or possibly a camera artifact tongue

 		cjtenny just told me about the Kickstarter campaign; I'd been looking at this thread every so often for a while, but never in much detail. Selling a reliable small DRSSTC is a pretty good accomplishment; the user's manual looks great. Great work, all around.

been thinking about it...on one hand, it's a handful of components that makes the coil a lot more reliable; on the other hand, I've yet to blow up the coil (and this includes a couple of runs where the interrupter latched up high because I didn't shield it).
