Hebdarole

Hebdarole is a period-7 oscillator that was found by Noam Elkies in November 1997. It was originally found in the larger but more symmetric induction coil form shown below that creates 2 sparks. The smaller version shown to the right was found soon after by Alan Hensel using a component found by David Buckingham in June 1977, but that only creates one domino spark.

gollark: Meanwhile on Trade Hub Feedback: People attempt to puzzle out rules!
gollark: Eh, doesn't matter that much, it's still quite a sensible thing to do.
gollark: Anyway, if this works I shall be very happy, and also probably get a bunch of cool rares or something.
