Status
Completed, and I believe the circuit has been debugged. It sparks well, but I think the voltage boost is not enough to jump a decent sized gap to allow thermal convection to occur and let the spark rise. Still looking into it.
Justification
Come on, a desktop Jacob's Ladder run off AA batteries? Too Fucking Cool.
