[PSUBS-MAILIST] next project

[Alan via Personal_Submersibles]

Hank,
yes mad! I'll send you over the some control electronics once I've
made mine up.
Keep it in mind that those solenoids  may require pressure to assist opening
in case the last bit of air isn't coming out.

This will be a real easy job and quick to install.  Gamma will be out of Quarantine in a week so I need to have these things done.  I am trying to get permission to dive in Lake Louise in the Banff National Park.
