hi wayneh.
sorry for the long absence. work tears me away from the human race occasionally and my computer giving up the smoke right before i left didn't help either.

as for the multi layer i was thinking more i terms of the tongue electrode. it is 9x16 terminals so im not sure how i would construct that with only one layer. and as you pointed out it cant have any nasty stuff in it as it will be in the mouth and potentially electrolizing.

 

Nathan i am trying to do exactly the same thing. If you are still on this group I would very much like to discuss.

Nathan hasn't been seen here for 8 years, so I doubt he'll answer.
