Update, I am having construction issues that maybe someone here can help with. As this is only a test cell I am looking for proving a concept not trying to win any cell building awards.
With a single cell i had exposed wire wrapped around the external tube and a split pin spread out with a wire connected to make the connection to the inner tube. This worked fine for a single cell. Now i need to connect all of them in parallel. This will also need to be encased in the water container. NOw here lies the issue, all exposed connections must be "contained" within their alloted fields (in other words no direct lines between opposing charges, as this causes leakage and an unreliable connection. if the connecting wires are too long the measurable capacitance is not stable.
I am trouble shooting some ideas but i keep running into too much leakage or the capacitance isn't stable enough to work with. Any ideas here would be nice, at this stage i am considering a water tight base and running the connections through there. this will require more construction time then i would of hopped for.
