Tired.

So tired. Not really sure why, but meh. Trucking on.
How would I determine the crush pressure of a submersible. Obvious idea would be building it and then applying pressure until it cracked like an egg. Of course while commuting home with the Wif last night I remembered that mineral oil is electrically chill. I could just fill it with mineral oil. I’d have to check the pressure characteristics. Probably decide on the scope of the project.
I want to see the bottom of Greenlake. Blackman’s Lake would be dope as well.
If I went longer on the deployment, I’d need a charging system. I was thinking bring out to neutral buoyancy a few inches under the waters surface. Sugar cells on the top should be able to charge during peak hours, and then it could sink down again when the light is no longer enough. Just an idea.
