Awesome. Thanks for posting the update !!

Welcome back, Eric! The Arduino software based on your work has been successfully in use in my subs for about a year now. I would suggest using a genuine Arduino for reliability. (I have had problems with cheap clones). My Github site has my updated software.

Ivan, I don't want to curb your enthusiasm but making your own piston tank for a first model may be a lot to take on. You will, I think, need a lathe to make a piston tank. And yes one of the advantages is that you can custom build a tank for the model. I have made about 4!

Some different construction ideas over here:

Also if you Google: submarine piston tanks lothar mentz

You should find a very useful guide by Lothar on building tanks. (It is a pdf file so I can't post it here.)
