I had to bump this thread, It deservers to be on front page.. Where are the updates man?
Hey Ben,

Thanks for the kind words. I've been working hard on this project and made a ton of progress in the past few months, but the progress has been much slower than I had hoped. It's almost done, but I anticipate running into a lot of trouble with the projectile feed mechanism so it might be a few more months until it's done.

As best as I can tell so far, overvotlage killed the IGBT. I think the communtation resistor I used is too high of a value.
