Thanks, I'll have to aspire to get one. I'm an electronics dummy.

By the way--when you build your subs with their modular capsules, Captain, what's your preferred method to accommodate electrical connections that have to penetrate the hull?

I'm finding that connections onto a bolt with its head held to the outside of the hull (a flat resin end cap, that is) hold up ok, but I can't shortcut by just having a wire through the hull and putting silicone around.
