Hot Diggity, that's spiffy.  <img src="/images/graemlins/smile.gif" alt="" />
My only concern about this is the plastic vial and glue to seal it up.  Isn't the Miox using a glass chamber?  But it looks like one could replicate the anode and cathode used pretty effectively.  I don't think I would worry about the plastic & glue at first, but I expect they might break down over time.
That's pretty damn cool Bill.
